Infiniti Q50 Hybrid (2018 year). Manual — part 20

wheel, may reduce the steering per-
formance.

Direct Adaptive Steering is designed to
control the steering force and steering angle
according to the vehicle speed and amount
of turning of the steering wheel.

The steering characteristic can be selected
using the INFINITI Drive Mode Selector. See
“INFINITI Drive Mode Selector” (P.5-21).

If the VDC system is turned off, the setting
of steering becomes Standard mode.

If the power steering warning light illumi-
nates while the hybrid system is running, it
may indicate that Direct Adaptive Steering is
not functioning properly and may need
servicing. It is recommended you have the
system checked by an INFINITI retailer. (See
“Power steering warning light” (P.2-14).)

When the power steering warning light
illuminates with the hybrid system running,
the power assist for the steering will cease
operation. You will still have control of the
vehicle. However, greater steering effort will
be needed, especially in sharp turns and at
low speeds.

If Direct Adaptive Steering is malfunction-
ing, the steering wheel may turn slightly even
when driving on a straight road.

Under the following conditions, the steering

wheel may turn slightly even when driving on
a straight road. This is due to a protection
mechanism for Direct Adaptive Steering. The
steering wheel will return to the normal
position after the protection mechanism is
deactivated.

Condition A
. When the engine is stalled or likely to be

stalled

. When the steering wheel is held in the full

lock position or when the front tire
touches an obstruction.

. When the battery is discharged
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and stop operating the steering wheel. Then
drive the vehicle for a short period of time.

Condition B
. When the steering wheel is operated

repeatedly or continuously while parking
or driving at a very low speed. In this
case, the power assist for the steering
wheel will be reduced.

To return the steering wheel to the normal
position, stop the vehicle in a safe location
and wait for a period of time, without
operating the steering wheel, until the
temperature of Direct Adaptive Steering
cools down. Avoid repeated steering wheel
operations that could cause Direct Adaptive
Steering to overheat.

When the vehicle is tested on the 2-wheel
dynamometer, the power steering warning
light may illuminate. To turn off the power
steering warning light, stop the vehicle in a
safe location, turn the hybrid system off,
restart the hybrid system, and then drive the
vehicle for a period of time.

The following conditions do not indicate a
malfunction of Direct Adaptive Steering.
. You may notice wider steering play when

the ignition switch is in the OFF or ACC
position compared to when it is in the
ON position.

. After the hybrid system is started, the

steering wheel may turn slightly even
when driving on a straight road. To
return to the normal position, drive the
vehicle on a straight road for a period of
time.

. After the hybrid system is started, the

steering wheel may move if the steering
wheel was turned to the fully locked
position while the ignition switch was in
the OFF position.

. After the vehicle is tested on the 4-wheel

dynamometer, the steering wheel may
turn slightly even when driving on a
straight road. To return the steering
wheel to the normal position, drive the
vehicle on a straight road for a period of
time.

Starting and driving

You may hear a noise under the following
conditions. However, this is not a malfunc-
tion.
. When the hybrid system is started or

stopped.

. When the steering wheel is turned in the

full lock position.

BRAKING PRECAUTIONS

This vehicle is equipped with two braking
systems.
. Hydraulic brake system

. Regenerative brake system

Hydraulic brake system

The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.

Regenerative brake system

See “Regenerative brake” (P.Hybrid System-
8).

Using the brakes

Avoid resting your foot on the brake pedal
while driving. This will cause overheating of
the brakes, wearing out the brake and pads
faster and reduce gas mileage.

To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance and
could result in loss of vehicle control.

WARNING

. While driving on a slippery surface,

be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.

. If the INFINITI Direct Response Hy-

brid

®

System is not running or is

turned off while driving, the power
assist for the brakes will be limited.
Braking will be harder.

CAUTION

You may hear a operational noise when
the brake pedal is depressed. This is not a
malfunction.

Wet brakes

When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be longer
and the vehicle may pull to one side during
braking.

To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake pedal

BRAKE SYSTEM

to heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.

PARKING BRAKE BREAK-IN

Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced, in
order to assure the best braking perfor-
mance.

This procedure is described in the vehicle
service manual. It is recommended you visit
an INFINITI retailer for this service.

BRAKE ASSIST

When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even with
light pedal force.

WARNING

The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.

ANTI-LOCK BRAKING SYSTEM
(ABS)

WARNING

. The Anti-lock Braking System (ABS)

is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that
stopping distances on slippery sur-

faces will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered roads,
or if you are using tire chains. Always
maintain a safe distance from the
vehicle in front of you. Ultimately,
the driver is responsible for safety.

. Tire type and condition may also

affect braking effectiveness.

— When replacing tires, install the

specified size of tires on all four
wheels.

— For detailed information, see

“Wheels and tires” (P.8-28) of
this manual.

The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during
hard braking or when braking on slippery
surfaces. The system detects the rotation
speed at each wheel and varies the brake
fluid pressure to prevent each wheel from
locking and sliding. By preventing each
wheel from locking, the system helps the
driver maintain steering control and helps to
minimize swerving and spinning on slippery
surfaces.

Starting and driving

5-129

BRAKE ASSIST

5-130

Starting and driving

Using the system

Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid
obstacles.

WARNING

Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.

Self-test feature

The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic
feature that tests the system each time you
start the hybrid system and move the vehicle
at a low speed in forward or reverse. When
the self-test occurs, you may hear a “clunk”
noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a mal-
function, it switches the ABS off and
illuminates the ABS warning light on the
instrument panel. The brake system then
operates normally, but without anti-lock
assistance.

If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked. It is recommended you visit
an INFINITI retailer for this service.

Normal operation

The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).

When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsation
in the brake pedal and hear a noise from
under the hood or feel a vibration from the
actuator when it is operating. This is normal
and indicates that the ABS is operating
properly. However, the pulsation may indi-
cate that road conditions are hazardous and
extra care is required while driving.

The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving
conditions, the VDC system helps to perform
the following functions.
. Controls brake pressure to reduce wheel

slip on one slipping drive wheel so power
is transferred to a non slipping drive
wheel on the same axle.

. Controls brake pressure and engine or

motor output to reduce drive wheel slip
based on vehicle speed (traction control
function).

. Controls brake pressure at individual

wheels and engine or motor output to
help the driver maintain control of the
vehicle in the following conditions:
— understeer (vehicle tends to not follow

the steered path despite increased
steering input)

— oversteer (vehicle tends to spin due to

certain road or driving conditions).

The VDC system can help the driver to
maintain control of the vehicle, but it cannot
prevent loss of vehicle control in all driving
situations.

When the VDC system operates, the VDC
warning light

in the instrument panel

flashes so note the following:
. The road may be slippery or the system

may determine some action is required to

VEHICLE DYNAMIC CONTROL
(VDC) SYSTEM

help keep the vehicle on the steered path.

. You may feel a pulsation in the brake

pedal and hear a noise or vibration from
under the hood. This is normal and
indicates that the VDC system is working
properly.

. Adjust your speed and driving to the road

conditions.

See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-15).

If a malfunction occurs in the system, the
VDC warning light

illuminates in the

instrument panel. The VDC system automa-
tically turns off.

The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator light
illuminates to indicate the VDC system is off.
When the VDC switch is used to turn off the
system, the VDC system still operates to
prevent one drive wheel from slipping by
transferring power to a non slipping drive
wheel. The VDC warning light

flashes if

this occurs. All other VDC functions are off,
except for rise-up and build-up, and brake
force distribution, and the VDC warning
light

will not flash. The VDC system is

automatically reset to on when the ignition
switch is placed in the off position then back
to the on position.

See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-15) and “Vehicle Dynamic

Control (VDC) off indicator light” (P.2-17).

The computer has a built-in diagnostic
feature that tests the system each time you
start the INFINITI Direct Response Hybrid

®

System and move the vehicle forward or in
reverse at a slow speed. When the self-test
occurs, you may hear a “clunk” noise and/or
feel a pulsation in the brake pedal. This is
normal and is not an indication of a mal-
function.

RISE-UP AND BUILD-UP

The system gradually adjusts braking power
during normal braking to help provide an
enhanced brake feel.

BRAKE FORCE DISTRIBUTION

During braking while driving through turns,
the system optimizes the distribution of
force to each of the four wheels depending
on the radius of the turn.

WARNING

. The VDC system is designed to help

the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed
and be especially careful when driving

and cornering on slippery surfaces
and always drive carefully.

. The rise-up and build-up, and brake

force distribution system may not be
effective depending on the driving
condition. Always drive carefully and
attentively.

. Do not modify the vehicle’s suspen-

sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not INFINITI recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the VDC warning light

may

illuminate.

. If brake related parts such as brake

pads, rotors and calipers are not
INFINITI recommended or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light

may illumi-

nate.

. If engine control related parts are not

INFINITI recommended or are extre-
mely deteriorated, the VDC warning
light

may illuminate.

. When driving on extremely inclined

surfaces such as higher banked cor-

Starting and driving

Starting and driving

ners, the VDC system may not oper-
ate properly and the VDC warning
light

may illuminate. Do not drive

on these types of roads.

. When driving on an unstable surface

such as a turntable, ferry, elevator or
ramp, the VDC warning light

may

illuminate. This is not a malfunction.
Restart the hybrid system after driv-
ing onto a stable surface.

. If wheels or tires other than the

INFINITI recommended ones are
used, the VDC system may not oper-
ate properly and the VDC warning
light

may illuminate.

. The VDC system is not a substitute

for winter tires or tire chains on a
snow covered road.

This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels to help smooth vehicle
response.

When the SPORT mode is selected by the
INFINITI Drive Mode Selector, the amount
of brake control provided by the active trace
control is reduced.

When the PERSONAL mode is selected, the
active trace control can be set to ON
(enabled) or OFF (disabled). See “INFINITI
Drive Mode Selector” (P.5-21).

When the VDC OFF switch is used to turn
off the VDC system, the active trace control
is also turned off.

ACTIVE TRACE CONTROL

JVS0249X

When the active trace control is operated
and the “Chassis Control” mode is selected in
the trip computer, the active trace control
graphics are shown in the vehicle informa-
tion display. (See “Trip computer” (P.2-27).)

If the chassis control warning message
appears in the vehicle information display,
it may indicate that the active trace control
is not functioning properly. It is recom-
mended you have the system checked by
an INFINITI retailer. (See “31. Chassis con-
trol warning” (P.2-23).)

WARNING

The active trace control may not be
effective depending on the driving con-
dition. Always drive carefully and atten-
tively.

When the active trace control is operating,
you may feel a pulsation in the brake pedal
and hear a noise. This is normal and indicates
that the active trace control is operating
properly.

Even if the active trace control is set to OFF,
some functions will remain on to assist the

driver (for example, avoidance scenes).

Starting and driving

WARNING

. Never rely solely on the hill start

assist system to prevent the vehicle
from moving backward on a hill.
Always drive carefully and atten-
tively. Depress the brake pedal when
the vehicle is stopped on a steep hill.
Be especially careful when stopped
on a hill on frozen or muddy roads.
Failure to prevent the vehicle from
rolling backwards may result in a loss
of control of the vehicle and possible
serious injury or death.

. The hill start assist system is not

designed to hold the vehicle at a
standstill on a hill. Depress the brake
pedal when the vehicle is stopped on
a steep hill. Failure to do so may
cause the vehicle to roll backwards
and may result in a collision or serious
personal injury.

. The hill start assist system may not

prevent the vehicle from rolling back-
wards on a hill under all load or road
conditions. Always be prepared to
depress the brake pedal to prevent
the vehicle from rolling backwards.
Failure to do so may result in a
collision or serious personal injury.

The hill start assist system automatically
keeps the brakes applied to help prevent the
vehicle from rolling backwards in the time it
takes the driver to release the brake pedal
and apply the accelerator when the vehicle is
stopped on a hill.

The hill start assist system will operate
automatically under the following condi-
tions:
. The transmission is shifted to a forward

or reverse gear.

. The vehicle is stopped completely on a hill

by applying the brake.

The maximum holding time is 2 seconds.
After 2 seconds the vehicle will begin to roll
back and the hill start assist system will stop
operating completely.

The hill start assist system will not operate
when the transmission is shifted to the N
(Neutral) or P (Park) position or on a flat and
level road.

The chassis control is an electric control
module that includes the following func-
tions:
. Log-in function (See “Log-in function”

(P.3-15).)

. INFINITI Drive Mode Selector (See

“INFINITI Drive Mode Selector” (P.5-
21).)

. Active Lane Control (if so equipped) (See

“Active Lane Control” (P.5-24).)

. Active Trace Control (See “Active trace

control” (P.5-132).)

FREEING A FROZEN DOOR LOCK

To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before insert-
ing it into the key hole or use the Intelligent
Key system.

ANTIFREEZE

In the winter when it is anticipated that the
outside temperature will drop below 32°F
(0°C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-5) and
“Inverter cooling system” (P.8-7).

12-VOLT BATTERY

If the 12-volt battery is not fully charged
during extremely cold weather conditions,
the battery fluid may freeze and damage the
12-volt battery. To maintain maximum effi-
ciency, the 12-volt battery should be
checked regularly. For additional informa-
tion, see “12-volt battery” (P.8-14).

DRAINING OF COOLANT WATER

If the vehicle is to be left outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For details, see “Engine cooling
system” (P.8-5) and “Inverter cooling sys-
tem” (P.8-7).

TIRE EQUIPMENT

SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels. It is
recommended you consult an INFINITI re-
tailer for the tire type, size, speed rating and
availability information.

For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.

Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.

Tire chains may be used. For details, see
“Tire chains” (P.8-35) of this manual.

Intelligent All-Wheel Drive (AWD)
models

If you install snow tires, they must also be
the same size, brand, construction and tread
pattern on all four wheels.

SPECIAL WINTER EQUIPMENT

It is recommended that the following items
be carried in the vehicle during winter:
. A scraper and stiff-bristled brush to

remove ice and snow from the windows
and wiper blades.

. A sturdy, flat board to be placed under

the jack to give it firm support.

. A shovel to dig the vehicle out of

snowdrifts.

. Extra window washer fluid to refill the

reservoir tank.

DRIVING ON SNOW OR ICE

WARNING

. Wet ice (32°F, 0°C and freezing rain),

very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip”
under these conditions. Try to avoid
driving on wet ice until the road is
salted or sanded.

. Whatever the condition, drive with

caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels will
lose even more traction.

Starting and driving

5-135

COLD WEATHER DRIVING

5-136

Starting and driving

. Allow more stopping distance under

these conditions. Braking should be
started sooner than on dry pave-
ment.

. Allow greater following distances on

slippery roads.

. Watch for slippery spots (glare ice).

These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steer-
ing maneuvers.

. Do not use the cruise control on

slippery roads.

. Snow can trap dangerous exhaust

gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.

ENGINE BLOCK HEATER (if so
equipped)

Engine block heaters are used to assist in
cold temperature starting.

The engine block heater should be used
when the outside temperature is 20°F
(−7°C) or lower.

To use the engine block heater

1. Turn the INFINITI Direct Response Hy-

brid

®

System off.

2. Open the hood and unwrap the engine

block heater cord.

3. Plug the engine block heater cord into a

grounded 3-wire, 3-pronged extension
cord.

4. Plug the extension cord into a Ground

F a u l t I n t e r r u p t ( G F I ) p r o t e c t e d ,
grounded 110-volt AC (VAC) outlet.

5. The engine block heater must be plugged

in for at least 2 - 4 hours, depending on
outside temperatures, to properly warm
the engine coolant. Use an appropriate
timer to turn the engine block heater on.

6. Before starting the hybrid system, un-

plug and properly store the cord to keep
it away from moving parts.

WARNING

. Do not use your engine block heater

with an ungrounded electrical system
or a 2-pronged adapter. You can be
seriously injured by an electrical
shock if you use an ungrounded
connection.

. Disconnect and properly store the

engine block heater cord before
starting the hybrid system. Damage
to the cord could result in an elec-
trical shock and can cause serious
injury.

. Use a heavy-duty 3-wire, 3-pronged

extension cord rated for at least 10A.
Plug the extension cord into a Ground
Fault Interrupt (GFI) protected,
grounded 110-VAC outlet. Failure
to use the proper extension cord or
a grounded outlet can result in a fire
or electrical shock and cause serious
personal injury.

HAZARD WARNING FLASHER SWITCH

ROADSIDE ASSISTANCE PROGRAM

To shut off the INFINITI Direct Response
Hybrid

®

System in an emergency situation

while driving, perform the following proce-
dure:
. Rapidly push the push-button ignition

switch 3 consecutive times in less than
1.5 seconds, or

. Push and hold the push-button ignition

switch for more than 2 seconds.

Your vehicle is equipped with run-flat tires
and you can continue driving to a safe
location even if they are punctured. (See
“Run-flat tires” (P.8-34).)

TIRE PRESSURE MONITORING
SYSTEM (TPMS)

This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit and the “Tire Pressure Low - Add
Air” warning appears in the vehicle informa-
tion display, one or more of your tires is
significantly under-inflated. If the vehicle is
being driven with low tire pressure, the
TPMS will activate and warn you of it by
the low tire pressure warning light. This
system will activate only when the vehicle is
driven at speeds above 16 MPH (25 km/h).
For more details, see “Low tire pressure
warning light” (P.2-12) and “Tire Pressure
Monitoring System (TPMS)” (P.5-5).

WARNING

. Radio waves could adversely affect

electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences

before use.

. If the low tire pressure warning light

illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
after adjusting the tire pressure, a
tire may be flat.

. When a wheel is replaced, the TPMS

will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on after 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended you visit an INFINITI retailer
for these services.

the proper operation of the TPMS.

. Do not inject any tire liquid or aerosol

tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.

RUN-FLAT TIRES

Run-flat tires are those tires that can be
used temporarily if they are punctured. See
“Run-flat tires” (P.8-34).

Also, refer to “Important Tire Safety Infor-
mation” (US) or “Tire Safety Information”
(Canada) in the INFINITI Warranty Informa-
tion Booklet.

WARNING

. Although you can continue driving

with a punctured run-flat tire, re-
member that vehicle handling stabi-
lity is reduced, which could lead to an
accident and personal injury. Also,
driving a long distance at high speeds
may damage the tires.

. Do not drive at speeds above 50

MPH (80 km/h) and do not drive
more than approximately 93 miles

(150 km) with a punctured run-flat
tire. The actual distance the vehicle
can be driven on a flat tire depends on
outside temperature, vehicle load,
road conditions and other factors.

. Drive safely at reduced speeds. Avoid

hard cornering or braking, which may
cause you to lose control of the
vehicle.

. If you detect any unusual sounds or

vibrations while driving with a punc-
tured run-flat tire, pull off the road
to a safe location and stop the vehicle
as soon as possible. The tire may be
seriously damaged and need to be
replaced.

CAUTION

. Never install tire chains on a punctu-

red run-flat tire, as this could damage
your vehicle.

. Avoid driving over any projection or

pothole, as the clearance between
the vehicle and the ground is smaller
than normal.

. Do not enter an automated car wash

with a punctured run-flat tire.

. It is recommended you have the

punctured tire inspected by an
INFINITI retailer or other authorized
repair shop. Replace the tire as soon
as possible if the tire is seriously
damaged.

If you have a flat tire and have to stop the
vehicle, follow the instructions below.

1. Safely move the vehicle off the road and

away from traffic.

2. Turn on the hazard warning flashers.

3. Park on a level surface and apply the

parking brake. Move the shift lever to the
P (Park) position.

4. Turn off the hybrid system.

5. Raise the hood to warn other traffic, and

to signal professional road assistance
personnel that you need assistance.

6. Have all passengers get out of the

vehicle and stand in a safe place, away
from traffic and clear of the vehicle.

For the tire removing procedure, see “Jack-
ing up the vehicle and replacing tires” (P.8-
39).
