Infiniti QX50 (2019 year). Manual — part 28

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

3. Tire chains may be used. For additional

information, refer to “Tire chains” in the
“Do-it-yourself” section of this manual.

SPECIAL WINTER EQUIPMENT

It is recommended that the following items
be carried in the vehicle during winter:

∙ A scraper and stiff-bristled brush to re-

move 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 snow-

drifts.

∙ Extra

washer

fluid

to

refill

the

windshield-washer fluid reservoir.

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 cau-

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

∙ Allow more stopping distance under

these conditions. Braking should be
started sooner than on dry pavement.

∙ 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 steering 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 with
cold temperature starting.

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

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 en-
gine. Damage to the cord could result in
an electrical shock and can cause serious
injury.

5-192

Starting and driving

∙ Use a heavy-duty 3-wire, 3-pronged ex-

tension cord rated for at least 10 A. 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 out-
let can result in a fire or electrical shock
and cause serious personal injury.

To use the engine block heater:

1. Turn the engine 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

Fault

Interrupt

(GFI)

protected,

grounded 110-volt AC (VAC) outlet.

5. The engine block heater must be

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

6. Before starting the engine, unplug and

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

ACTIVE NOISE CANCELLATION

This system uses microphones

䊊

located in-

side the vehicle to detect engine booming
noise. The system then automatically gener-
ates a noise canceling sound through the
speakers and woofer (if so equipped) to re-
duce engine booming noise.

NOTE:

To operate the active noise cancellation sys-
tem properly:

∙ Do not cover the speakers or woofer (if

so equipped).

In case of emergency

To shut off the engine in an emergency situ-
ation while driving, perform the following
procedure:

– Rapidly push the push-button ignition

switch three consecutive times in less than
1.5 seconds, or

TIRE PRESSURE MONITORING
SYSTEM (TPMS)

This vehicle is equipped with Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires. When the low tire pres-
sure warning light is lit, and the “Tire Pressure
Low - Add Air” warning appears in the vehicle
information display, one or more of your tires
is significantly under-inflated. The system
also displays pressure of all tires (except the
spare tire) on the vehicle information display
screen by sending a signal from a sensor that
is installed in each wheel. 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 acti-
vate only when the vehicle is driven at speeds
above 16 mph (25 km/h). For additional in-
formation, refer to “Warning lights, indicator
lights and audible reminders” in the “Instru-
ments and controls” section and “Tire Pres-
sure Monitoring System (TPMS)” in the
“Starting and driving” sections of this manual.

WARNING

∙ Radio waves could adversely affect elec-

tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.

∙ If the low tire pressure warning light illu-

minates while driving, avoid sudden
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 recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
OFF. If you have a flat tire, replace it with
a replacement tire as soon as possible.

EMERGENCY ENGINE SHUT OFF

FLAT TIRE

In case of emergency

6-3

∙ When replacing a wheel without TPMS

such as the spare tire, TPMS will not
function and the low tire pressure warn-
ing 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 recommended that you visit
an INFINITI retailer for these services.

∙ Replacing tires with those not originally

specified by INFINITI could affect 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 pressure sensors.

RUN-FLAT TIRES

This vehicle is equipped with run-flat tires.
Run-flat tires can be used temporarily if they
are punctured. When the “Flat Tire — Visit
Dealer” warning appears in the vehicle infor-
mation display, one or more of your tires is
punctured. For additional information, refer
to “Run-flat tires” in the “Do-it-yourself” sec-
tion of this manual.

For additional information, refer to the tire
safety information in the Warranty Informa-
tion Booklet.

WARNING

∙ Although you can continue driving with a

punctured run-flat tire, remember that
vehicle handling stability is reduced,
which could lead to an accident and per-
sonal 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 dis-
tance the vehicle can be driven on a flat
tire depends on outside temperature, ve-
hicle 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 vi-

brations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously dam-
aged and need to be replaced.

CAUTION

∙ Never install tire chains on a punctured

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

∙ Avoid diving over any projection or pot-

hole, as the clearance between the ve-
hicle and the ground is smaller than
normal.

∙ Do not enter an automated car wash with

a punctured run-flat tire.

∙ Have the punctured tire inspected by an

INFINITI retailer or other authorized re-
pair shop. Replace the tire as soon as pos-
sible if the tire is seriously damaged.

6-4

In case of emergency

To start your engine with a booster battery,
the instructions and precautions below must
be followed.

WARNING

∙ If done incorrectly, jump starting can lead

to a battery explosion, resulting in severe
injury or death. It could also damage your
vehicle.

∙ Explosive hydrogen gas is always present

in the vicinity of the battery. Keep all
sparks and flames away from the
battery.

∙ Do not allow battery fluid to come into

contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a corro-
sive sulfuric acid solution which can cause
severe burns. If the fluid should come into
contact with anything, immediately flush
the contacted area with water.

∙ Keep battery out of the reach of children.

∙ The booster battery must be rated at

12 volts. Use of an improperly rated bat-
tery can damage your vehicle.

∙ Whenever working on or near a battery,

always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.

∙ Do not attempt to jump start a frozen

battery. It could explode and cause seri-
ous injury.

∙ The automatic engine cooling fan (if so

equipped) may come on at any time with-
out warning, even if the ignition switch is
in the OFF position and the engine is not
running. To avoid injury, keep hands and
other objects away from it.
