Infiniti QX50 (2021 year). Manual in english — page 26

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 dam-
age your vehicle.

•

Explosive hydrogen gas is always pres-
ent 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, imme-
diately 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 battery
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.

CAUTION

•

Always connect positive (+) to positive
(+) and negative (−) to body ground (for
example, strut mounting bolt, engine lift
bracket, etc.) — not to the battery.

•

Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal.

5. Start the engine of the booster vehicle and

let it run for a few minutes.

6. Keep the engine speed of the booster ve-

hicle at about 2,000 rpm and start the
engine of the vehicle being jump started.

CAUTION

Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, place the ignition
switch in the OFF position and wait 3 to 4
seconds before trying again.

7. After starting the engine, carefully discon-

nect the negative cable and then the posi-
tive cable.

In case of emergency

CAUTION

•

Continuously

Variable

Transmission

(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.

•

Do not push start this vehicle. The three-
way catalyst may be damaged.

WARNING

•

Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.

•

To avoid the danger of being scalded,
never remove the coolant reservoir cap
while the engine is still hot. When the
coolant reservoir cap is removed, pres-
surized hot water will spurt out, possibly
causing serious injury.

•

Do not open the hood if steam is coming
out.

If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc. take the following steps.

1. Move the vehicle safely off the road, apply

the parking brake and engage the P (Park)
position.

Do not stop the engine.

2. Turn off the air conditioner. Open all the

windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.

3. Get out of the vehicle. Look and listen for

steam or coolant escaping from the radia-
tor before opening the hood. (If steam or
coolant is escaping, turn off the engine.)
Do not open the hood further until no
steam or coolant can be seen.

4. Open the engine hood.

WARNING

If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.

5. Visually check drive belts for damage or

looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the
engine.

WARNING

Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.

6. After the engine cools down, check the

coolant level in the engine coolant reser-
voir tank with the engine running. Add
coolant to the engine coolant reservoir
tank if necessary. Have your vehicle re-
paired. It is recommended that you visit an
INFINITI retailer for this service.

When towing your vehicle, all jurisdictions
and local regulations for towing must be fol-
lowed. Incorrect towing equipment could
damage your vehicle. Towing instructions are
available from an INFINITI retailer. Local ser-
vice operators are generally familiar with the
applicable laws and procedures for towing.
To assure proper towing and to prevent ac-
cidental damage to your vehicle, INFINITI
recommends having a service operator tow
your vehicle. It is advisable to have the service
operator

carefully

read

the

following

precautions:

WARNING

•

Never ride in a vehicle that is being
towed.

•

Never get under your vehicle after it has
been lifted by a tow truck.

CAUTION

•

When towing, make sure that the trans-
mission, axles, steering system and pow-
ertrain are in working condition. Use dol-
lies or flatbed if any of the listed systems
are not working.

•

Always attach safety chains before
towing.

In order to maintain the appearance of your
vehicle, it is important to take proper care of
it.

To protect the paint surfaces, wash your ve-
hicle as soon as you can:
• After a rainfall to prevent possible damage

from acid rain.

• After driving on coastal roads.
• When contaminants such as soot, bird

droppings, tree sap, metal particles or bugs
get on the paint surface.

• When dust or mud builds up on the surface.

Whenever possible, store or park your vehicle
inside a garage or in a covered area.

When it is necessary to park outside, park in a
shady area or protect the vehicle with a body
cover.

Be careful not to scratch the paint surface
when putting on or removing the body cover.

WASHING

Wash dirt off with a wet sponge and plenty
of water. Clean the vehicle thoroughly using a
mild soap, a special vehicle soap or general
purpose dishwashing liquid mixed with clean,
lukewarm (never hot) water.

CAUTION

•

Do not concentrate water spray directly
on the sonar sensors (if so equipped) on
the bumper as this will result in damage
to the sensors. Do not use pressure
washers capable of spraying water over
1,200 psi (8,274 kPa) to wash your ve-
hicle. Use of high-pressure washers over
1,200 psi (8,274 kPa) can result in dam-
age to or removal of paint or graphics.
Avoid using a high-pressure washer
closer than 12 inches (30 cm) to the ve-
hicle. Always use a wide-angle nozzle
only, keep the nozzle moving and do not
concentrate the water spray on any one
area.

•

Do not use car washes that use acid in the
detergent. Some car washes, especially
brushless ones, use some acid for clean-
ing. The acid may react with some plastic
vehicle components, causing them to
crack. This could affect their appear-
ance, and also could cause them not to
function properly. Always check with
your car wash to confirm that acid is not
used.

•

Do not wash the vehicle with strong
household soap, strong chemical deter-
gents, gasoline or solvents.

•

Do not wash the vehicle in direct sunlight
or while the vehicle body is hot, as the
surface may become water-spotted.

•

Avoid using tight-napped or rough
cloths, such as washing mitts. Care must
be taken when removing caked-on dirt
or other foreign substances so the paint
surface is not scratched or damaged.

Rinse the vehicle thoroughly with plenty of
clean water.

Inside edges, seams and folds on the doors,
hatches and hood are particularly vulnerable
to the effects of road salt. Therefore, these
areas must be cleaned regularly. Take care
that the drain holes in the lower edge of the
door are open. Spray water under the body
and in the wheel wells to loosen the dirt and
wash away road salt.

A damp chamois can be used to dry the ve-
hicle to avoid water spots.

WAXING

Regular waxing protects the paint surface
and helps retain new vehicle appearance.
Polishing is recommended to remove built-up
wax residue and to avoid a weathered ap-
pearance before re-applying wax.

An INFINITI retailer can assist you in choos-
ing the proper product.

CLEANING EXTERIOR

7-2

Appearance and care

• Wax your vehicle only after a thorough

washing. Follow the instructions supplied
with the wax.

• Do not use a wax containing any abrasives,

cutting compounds or cleaners that may
damage the vehicle finish.

Machine compounding or aggressive polish-
ing on a base coat/clear coat paint finish may
dull the finish or leave swirl marks.

REMOVING SPOTS

Remove tar and oil spots, industrial dust, in-
sects, and tree sap as quickly as possible from
the surface of the paint to avoid lasting dam-
age or staining. Special cleaning products are
available at an INFINITI retailer or any auto-
motive accessory store. It is recommended
that you visit an INFINITI retailer for these
products.

UNDERBODY

In areas where road salt is used in winter, it is
necessary to clean the underbody regularly in
order to prevent dirt and salt from building up
and causing the acceleration of corrosion on
the underbody and suspension. Before the
winter period and again in the spring, the
underseal must be checked and, if necessary,
re-treated.

GLASS

Use glass cleaner to remove smoke and dust
film from the glass surfaces. It is normal for
glass to become coated with a film after the
vehicle is parked in the hot sun. Glass cleaner
and a soft cloth will easily remove this film.

CAUTION

When cleaning the inside of the windows,
do not use sharp-edged tools, abrasive
cleaners or chlorine-based disinfectant
cleaners. They could damage the electrical
conductors, radio antenna elements or rear
window defroster elements.

ALUMINUM ALLOY WHEELS

Wash the wheels regularly with a sponge
dampened in a mild soap solution, especially
during winter months in areas where road
salt is used. If not removed, road salt can
discolor the wheels.

CAUTION

Follow the directions below to avoid stain-
ing or discoloring the wheels:

•

Do not use a cleaner that uses strong acid
or alkali contents to clean the wheels.

•

Do not apply wheel cleaners to the
wheels when they are hot. The wheel
temperature should be the same as am-
bient temperature.

•

Rinse the wheel to completely remove
the cleaner within 15 minutes after the
cleaner is applied.

CHROME PARTS

Clean all chrome parts regularly with a non-
abrasive chrome polish to maintain the finish.

TIRE DRESSINGS

INFINITI does not recommend the use of tire
dressings. Tire manufacturers apply a coating
to the tires to help reduce discoloration of the
rubber. If a tire dressing is applied to the tires,
it may react with the coating and form a
compound. This compound may come off the
tire while driving and stain the vehicle paint.

If you choose to use a tire dressing, take the
following precautions:
• Use a water-based tire dressing. The coat-

ing on the tire dissolves more easily than
with an oil-based tire dressing.

• Apply a light coat of tire dressing to help

prevent it from entering the tire tread/
grooves (where it would be difficult to
remove).

Appearance and care

7-3

• Wipe off excess tire dressing using a dry

towel. Make sure the tire dressing is com-
pletely

removed

from

the

tire

tread/grooves.

• Allow the tire dressing to dry as recom-

mended by tire dressing manufacturer.

This vehicle has new and unique surfaces on
the center console and door pull finishers. If
cleaning is required use mild soap and water.
However if mild soap and water won’t clean
the center console and door pull finishers, use
Genuine INFINITI Vinyl and Leather Cleaner
(or equivalent).

Occasionally remove loose dust from the in-
terior trim, plastic parts and seats using a
vacuum cleaner or soft bristled brush. Wipe
the vinyl and leather surfaces with a clean,
soft cloth dampened in mild soap solution,
then wipe clean with a dry, soft cloth.

Regular care and cleaning is required in order
to maintain the appearance of the leather.

Before using any fabric protector, read the
manufacturer's

recommendations.

Some

fabric protectors contain chemicals that may
stain or bleach the seat material.

Use a cloth dampened only with water to
clean the meter and gauge lens.

Use a slightly moist (with water) microfiber
cloth to clean the wood trim. If necessary, use
water with natural soap or wood dedicated
cleaning products, such as furniture polish.

WARNING

Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can dam-
age the seat or occupant classification sen-
sor. This can also affect the operation of
the air bag system and result in serious per-
sonal injury.

CAUTION

•

Never use benzine, thinner, or any similar
material on the interior surfaces or sur-
face damage may occur. Such damage is
not

covered

under

the

INFINITI

warranty.

•

Small dirt particles can be abrasive and
damaging to leather surfaces and should
be removed promptly. Do not use saddle
soap, car waxes, polishes, oils, cleaning
fluids, solvents, detergents or ammonia-
based cleaners as they may damage the
leather's natural finish.

•

Never use fabric protectors unless rec-
ommended by the manufacturer.

•

Do not use glass or plastic cleaner on me-
ter or gauge lens covers. It may damage
the lens cover.

CLEANING INTERIOR

7-4

Appearance and care

LEATHER CLEANING KIT (if so
equipped)

Spray onto leather cleaning cloth, then gently
wipe the surface of the leather. Use a dry
towel to absorb any excess moisture.

Clean light-colored leather more frequently
because soiling on such surfaces is much
more visible.

Always follow the manufacturer’s instruc-
tions supplied with the leather cleaning kit.

You can obtain the leather cleaning kit from
an INFINITI retailer or other authorized repair
shop.

CAUTION

Do not leave the leather cleaning kit inside
the vehicle. The leather cleaning kit left in a
closed vehicle can become very hot.

AIR FRESHENERS

Most air fresheners use a solvent that could
affect the vehicle interior. If you use an air
freshener, take the following precautions:
• Hanging-type air fresheners can cause per-

manent discoloration when they contact
vehicle interior surfaces. Place the air fresh-
ener in a location that allows it to hang free
and not contact an interior surface.

• Liquid-type air fresheners typically clip on

the vents. These products can cause imme-
diate damage and discoloration when
spilled on interior surfaces.

Carefully read and follow the manufacturer's
instructions before using the air fresheners.

POWER MOONROOF (if so
equipped)

The sunshade is made from a tricot material.

CAUTION

To help prevent damaging the moonroof
while cleaning:

•

Do not rub the material with a cloth. Do-
ing so can damage the surface of the ma-
terial or cause a stain to spread.

•

Never use benzine, thinner or any similar
chemical to clean the sunshade. This may
discolor the moonroof and damage the
surface.

•

Clean water based stains by patting the
surface with a clean soft cloth dampened
in warm water. Press a clean dry cloth
onto the surface to remove as much
dampness as possible and then let air dry.

•

Clean oil based stains by patting the sur-
face with a clean soft cloth dampened in
warm water. Press a clean dry cloth onto
the surface to remove as much dampness
as possible and then let air dry.

Appearance and care

FLOOR MATS (if so equipped)

WARNING

To avoid potential pedal interference that
may result in a collision, injury or death:

•

NEVER place a floor mat on top of an-
other floor mat in the driver front posi-
tion or install them upside down or
backwards.

•

Use only Genuine INFINITI floor mats or
equivalent floor mats, specifically de-
signed for use in your vehicle model and
model year.

•

Properly position the mats in the floor-
well using the floor mat positioning
hook. For additional information, see
"Floor mat installation" (P. 7-6).

•

Make sure the floor mat does not inter-
fere with pedal operation.

•

Periodically check the floor mats to make
sure they are properly installed.

•

After cleaning the vehicle interior, check
the floor mats to make sure they are
properly installed.

The use of Genuine INFINITI floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular cleaning
and replaced if they become excessively
worn.

Floor mat installation

Your vehicle is equipped with floor mat re-
tainer clips. The number and shape of the
floor mat retainer clips for each seating posi-
tion varies depending on the vehicle.

When installing Genuine INFINITI floor mats,
follow the installation instructions provided
with the mat and the following:

1. With the ignition in the OFF position, the

shift lever in P (Park) position and with the
parking brake fully applied, position the
floor mat in the floorwell so that the floor
mat grommet holes are aligned with the
retainer clips.

2. Secure the grommet holes into the clips

and ensure that the floor mat is properly
positioned.

3. Make sure the floor mat does not inter-

fere with pedal operation. With the igni-
tion still in the OFF position, the shift lever
in the P (Park) position and with the park-
ing brake applied, fully apply and release
all pedals. The floor mat must not inter-
fere with pedal operation or prevent the
pedal

from

returning

to

its

normal

position.

It is recommended that you visit an INFINITI
retailer for details about installing the floor
mats in your vehicle.

LAI2094

7-6

Appearance and care

The illustration shows the location of the
floor mat retainer clips.

SEAT BELTS

The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solu-
tion. Allow the belts to dry completely in the
shade before using them. For additional in-
formation, see “Seat belt maintenance”
(P. 1-19).

WARNING

Do not allow wet seat belts to roll up in the
retractor. NEVER use bleach, dye or
chemical solvents to clean the seat belts,
since these materials may severely weaken
the seat belt webbing.

CLEANING THE SEAT TRACKS

CAUTION

Periodically clean the seat tracks to pre-
vent reduction of ability to move the seats.

Clean periodically with a high-powered
vacuum cleaner. Dirt and debris may reduce
the ability to adjust the seat. A wet cleansing
agent may be used if necessary.

MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION

Most vehicle corrosion is caused by:
• The accumulation of moisture-retaining

dirt and debris in body panel sections, cavi-
ties, and other areas.

• Damage to paint and other protective

coatings caused by gravel and stone chips
or minor traffic collisions.

ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION

Moisture

Accumulation of sand, dirt and water on the
vehicle body underside can accelerate corro-
sion. Wet floor coverings will not dry com-
pletely inside the vehicle and should be re-
moved for drying to avoid floor panel
corrosion.

LAI2095

Retainer clips

CORROSION PROTECTION

Appearance and care

7-7

Relative humidity

Corrosion will be accelerated in areas of high
relative humidity, especially those areas
where the temperatures stay above freezing
and where atmospheric pollution exists and
road salt is used.

Temperature

High temperatures accelerate the rate of cor-
rosion to those parts which are not well
ventilated.

Air pollution

Industrial pollution, the presence of salt in the
air in coastal areas, or heavy road salt use
accelerates the corrosion process. Road salt
also accelerates the disintegration of paint
surfaces.

PROTECT YOUR VEHICLE FROM
CORROSION

• Wash and wax your vehicle often to keep

the vehicle clean.

• Always check for minor damage to the

paint and repair it as soon as possible.

• Keep drain holes at the bottom of the doors

open to avoid water accumulation.

• Check the underbody for accumulation of

sand, dirt or salt. If present, wash with wa-
ter as soon as possible.

CAUTION

•

NEVER remove dirt, sand or other debris
from the passenger compartment by
washing it out with a hose. Remove dirt
with a vacuum cleaner or broom.

•

Never allow water or other liquids to
come in contact with electronic compo-
nents inside the vehicle as this may dam-
age them.

Chemicals used for road surface de-icing are
extremely corrosive. They accelerate corro-
sion and deterioration of underbody compo-
nents such as the exhaust system, fuel and
brake lines, brake cables, floor pan and
fenders.

In winter, the underbody must be cleaned
periodically.

For additional protection against rust and
corrosion, which may be required in some
areas, it is recommended that you consult an
INFINITI retailer.
