Infiniti Qx (2009 year). Manual — part 22
CAUTION
Automatic transmission models cannot
be push-started or tow-started. Attempt-
ing to do so may cause transmission
damage.
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 radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant reser-
voir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
● Do not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading and
the illumination of the engine oil pressure/engine
coolant temperature high indicator light), 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 move the shift lever to
P (Park).
Do not stop the engine.
2. Turn off the air conditioner. Open all the
windows, move the heater or air conditioner
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 radiator
before opening the hood. (If steam or cool-
ant 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 en-
gine.
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 cool-
ant level in the engine coolant reservoir tank
with the engine running. Add coolant to the
engine coolant reservoir tank if necessary.
Have your vehicle repaired at an INFINITI
dealer.
When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must be
followed. Incorrect towing equipment could dam-
age your vehicle. Towing instructions are avail-
able from an INFINITI dealer. Local service opera-
tors are generally familiar with the applicable laws
and procedures for towing. To assure proper
towing and to prevent accidental 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
powertrain are in working condition. If
any unit is damaged, dollies must be
used.
● Always attach safety chains before
towing.
For information about towing your vehicle behind
a recreational vehicle (RV), refer to “Flat towing”
in the “Technical and consumer information” sec-
tion of this manual.

INFINITI recommends that your vehicle be towed
with the driving (rear) wheels off the ground or
place the vehicle on a flat bed truck as illustrated.
CAUTION
● Never tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground
(forward or backward), as this may
cause serious and expensive damage to
the transmission. If it is necessary to
tow the vehicle with the front wheels
raised always use towing dollies under
the rear wheels.
● When towing automatic transmission
models with the front wheels on the
ground or on towing dollies:
– Turn the ignition key to the OFF po-
sition, and secure the steering wheel
in a straight-ahead position with a
rope or similar device. Never secure
the steering wheel by turning the ig-
nition key to the LOCK position. This
may damage the steering lock
mechanism.
If the speed or distance must necessarily be
greater, remove the propeller shaft before towing
to prevent damage to the transmission.

In order to maintain the appearance of your ve-
hicle, it is important to take proper care of it.
To protect the paint surfaces, please wash your
vehicle 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 drop-
pings, 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 use car washes that use acid in
the detergent. Some car washes, espe-
cially brushless ones, use some acid for
cleaning. The acid may react with some
plastic vehicle components, causing
them to crack. This could affect their
appearance, 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 sun-
light 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 sub-
stances so the paint surface is not
scratched or damaged.
Rinse the vehicle thoroughly with plenty of clean
water.
Inside flanges, 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 vehicle 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 appearance before
re-applying wax.
An INFINITI dealer can assist you in choosing the
proper product.
● Wax your vehicle only after a thorough wash-
ing. 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 polishing
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, insects,
and tree sap as quickly as possible from the
surface of the paint to avoid lasting damage or
staining. Special cleaning products are available
at an INFINITI dealer or any automotive accessory
store.
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 un-
derbody and suspension. Before the winter pe-
riod and again in the spring, the underseal must
be checked and, if necessary, retreated.
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 electri-
cal conductors, radio antenna elements or
rear window defroster elements.
ALUMINUM ALLOY WHEELS
Wash the wheels regularly with a sponge damp-
ened 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
staining 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 rub-
ber. 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 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 re-
move).
● 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.

Occasionally remove loose dust from the interior
trim, plastic parts and seats using a vacuum
cleaner or soft bristled brush. Wipe the vinyl and
leather surfaces with a clean, soft cloth damp-
ened 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 manu-
facturer’s recommendations. Some fabric pro-
tectors contain chemicals that may stain or
bleach the seat material.
Use a cloth dampened only with water to clean
the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifica-
tion sensor. This can also affect the opera-
tion of the air bag system and result in
serious personal injury.
CAUTION
● Never use benzine, thinner or any simi-
lar material.
● 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, deter-
gents 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
meter or gauge lens covers. It may dam-
age the lens cover.
FLOOR MATS
The use of genuine INFINITI floor mats can ex-
tend the life of your vehicle carpet and make it
easier to clean the interior. No matter what
mats are used, be sure they are fitted for
your vehicle and are properly positioned in
the footwell to prevent interference with
pedal operation. Mats should be maintained
with regular cleaning and replaced if they be-
come excessively worn.
Floor mat positioning aid
This vehicle includes two driver’s side front floor
mat brackets and one passenger’s side front floor
mat bracket to help keep your floor mats in place.
INFINITI floor mats have been specially designed
for your vehicle model. The driver’s side floor mat
has two grommet holes incorporated in it and the
passenger’s side has one grommet hole. Position
each mat by placing the floor mat bracket hook
through the floor mat grommet holes while cen-
tering the mat in the footwell.
Periodically check to make certain the mats are
properly positioned.

SEAT BELTS
The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solution.
Allow the belts to dry completely in the shade
before using them. See “Seat belt maintenance”
in the “Safety – Seats, seat belts and supplemen-
tal restraint system” section of this manual.
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.
MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
● The accumulation of moisture-retaining dirt
and debris in body panel sections, cavities,
and other areas.
● Damage to paint and other protective coat-
ings caused by gravel and stone chips or
minor traffic accidents.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on the ve-
hicle body underside can accelerate corrosion.
Wet floor coverings will not dry completely inside
the vehicle, and should be removed for drying to
avoid floor panel corrosion.
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 corro-
sion 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 acceler-
ates the corrosion process. Road salt also accel-
erates the disintegration of paint surfaces.
TO 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 water
as soon as possible.

CAUTION
● NEVER remove dirt, sand or other de-
bris 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
damage them.
Chemicals used for road surface de-icing are
extremely corrosive. They accelerate corrosion
and deterioration of underbody components
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 corro-
sion, which may be required in some areas, con-
sult an INFINITI dealer.

Your new INFINITI has been designed to have
minimum maintenance requirements with long
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your INFINI-
TI’s good mechanical condition, as well as its
emission and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives proper
maintenance. You are a vital link in the mainte-
nance chain.
Scheduled maintenance
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “INFINITI Service and Maintenance
Guide”. You must refer to that guide to ensure
that necessary maintenance is performed on your
INFINITI at regular intervals.
General maintenance
General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
maintenance procedures regularly as prescribed.
Performing general maintenance checks requires
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by you,
a qualified technician, or, if you prefer, an INFINITI
dealer.
Where to go for service
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected by an INFINITI dealer.
INFINITI technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-dealership training programs. They
are completely qualified to work on INFINITI ve-
hicles before they work on your vehicle, rather
than after they have worked on it.
You can be confident that an INFINITI dealer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
in a reliable and economical way.
During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause or have an
INFINITI dealer do it promptly. In addition, you
should notify an INFINITI dealer if you think that
repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with “*” is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood Check that the doors
and engine hood operate properly. Also ensure
that all latches lock securely. Lubricate hinges,
latches, latch pins, rollers and links as necessary.
Make sure that the secondary latch keeps the
hood from opening when the primary latch is
released.

When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights* Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)* When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation* Tires should be rotated every
7,500 miles (12,000 km).
Tires* Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, adjust the pressure in all tires, including the
spare, to the pressure specified. Check carefully
for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Wheel alignment and balance If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for wheel
alignment. If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing may be
needed.
● For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet .
Windshield Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
Windshield wiper blades* Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the ve-
hicle, etc.
Additional information on the following
items with an “*” is found later in this sec-
tion.
Accelerator pedal Check the pedal for smooth
operation and make sure the pedal does not bind
or require uneven effort. Keep the floor mat away
from the pedal.
Automatic transmission P (Park) position
mechanism On a fairly steep hill check that your
vehicle is held securely with the shift selector
lever in the P (Park) position without applying any
brakes.
Brake pedal Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down fur-
ther than normal, the pedal feels spongy or the
vehicle seems to take longer to stop, see an
INFINITI dealer immediately. Keep the floor mat
away from the pedal.
Brakes Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake Check the parking brake opera-
tion regularly. The vehicle should be securely held
on a fairly steep hill with only the parking brake
applied. If the parking brake needs adjustment,
see an INFINITI dealer.
Seats Check seat position controls such as seat
adjusters, seatback recliner, etc. to ensure they
operate smoothly and all latches lock securely in
every position. Check that the head restraints
move up and down smoothly and the locks (if so
equipped) hold securely in all latched positions.
Seat belts Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,

and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Steering wheel Check for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimes Make sure all
warning lights and chimes are operating properly.
Windshield wiper and washer* Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defroster Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel).
Battery* Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake fluid level* Make sure that the brake fluid
level is between the MIN and MAX lines on the
reservoir.
Engine coolant level* Check the coolant level
when the engine is cold.
Engine drive belts* Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level* Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust system Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by an INFINITI dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Fluid leaks Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.
Power steering fluid level* and lines Check
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
Underbody The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield washer fluid* Check that there is
adequate fluid in the reservoir.

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
● Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift selector
lever to P (Park).
● Be sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
● Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition key is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
● If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
● It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle.
● If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
● Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
● Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
● On gasoline engine models, the fuel
filter or fuel lines should be serviced by
an INFINITI dealer because the fuel
lines are under high pressure even
when the engine is off.
CAUTION
● Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
● Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
● Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
● Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A genuine INFINITI service manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “Technical and consumer
information” section of this manual.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage. If in doubt about any servicing,
have it done by an INFINITI dealer.
