VEHICLE RECOVERY (freeing a
stuck vehicle)
WARNING
.Stand clear of a stuck vehicle.
. Do not spin your tires at high speed.
This could cause them to explode and
result in serious injury. Parts of your
vehicle could also overheat and be
damaged.
Pulling a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device
designed specifically for vehicle recovery.
Always follow the manufacturer’s instruc-
tions for the recovery device.
Attach the tow strap to the towing hook.
CAUTION
.Tow chains or cables must be at-
tached only to the main structural
members of the vehicle or the towing
hooks. Otherwise, the vehicle body
will be damaged. .
Use the towing hook only to free a
vehicle stuck in sand, snow, mud, etc.
Never tow the vehicle for a long
distance using only the towing hook.
. The towing hook is under tremendous
force when used to free a stuck
vehicle. Never pull the hook at an
angle.
. Always pull the cable straight out
from the front or rear of the vehicle.
. Pulling devices should be routed so
they do not touch any part of the
suspension, steering, brake or cooling
systems.
. Pulling devices such as ropes or
canvas straps are not recommended
for use in vehicle towing or recovery.
Rocking a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control
(VDC) system.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward.

7-2Appearance and care
In order to maintain the appearance of your
vehicle, it is important to take proper care of
it.
To protect the paint surface, wash your
vehicle as soon as you can:
.after a rainfall to prevent possible da-
mage 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 the vehicle 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,
especially brushless ones, use some
acid for cleaning. The acid may react
with some plastic vehicle compo-
nents, 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 de-
tergents, 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.
. Lock all doors before going through
automatic car wash. Locking doors
helps prevent fuel-filler door from
opening and becoming damaged.
Rinse the vehicle again 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 regularly cleaned. Make sure
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.
Avoid leaving water spots on the paint
surface by using a damp chamois to dry the
vehicle.
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 reapplying wax.
An INFINITI retailer can assist you in choos-
ing the proper product.
CLEANING EXTERIOR

.Wax your vehicle only after a thorough
washing. Follow the instructions sup-
plied with the wax.
. Do not use a wax containing any abra-
sives, cutting compounds or cleaners
that may damage the vehicle finish.
Machine compound 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 paint surface to avoid lasting
damage or staining. Special cleaning pro-
ducts are available at an INFINITI retailer or
any automotive accessory stores.
UNDERBODY
In areas where road salt is used in winter, the
underbody must be cleaned regularly. This
will 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 win-
dows, do not use sharp-edged tools,
abrasive cleaners or chlorine-based dis-
infectant cleaners. They could damage
the electrical conductors, radio antenna
elements or rear window defroster ele-
ments.
WHEELS
Wash the wheels when washing the vehicle
to maintain their appearance.
. Clean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
. Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
. INFINITI recommends that the road
wheels be waxed to protect against road
salt in areas where it is used during winter.
CAUTION
Do not use abrasive cleaners when
washing the wheels.
Aluminum alloy wheels
Wash regularly with a sponge dampened in a
mild soap solution, especially during winter
months in areas where road salt is used. Salt
could discolor the wheels if not removed.
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
ambient temperature.
. Rinse the wheel to completely re-
move the cleaner within 15 minutes
after the cleaner is applied.
Appearance and care7-3

7-4Appearance and care
Bright wheels (if so equipped)
The bright wheels use a different coating
process than typical aluminum alloy wheel
and they are not plated wheels. These
wheels are clear-coated and require the
following special cleaning. They should be
regularly washed with a soft sponge soaked
in a lot of water. After washing with water,
wipe clean with a dry, soft cloth and dry
completely. When there is chemical or tire
wax, or dirt such as an antifreeze agent on
the surface, wash them with water as soon
as possible.
CAUTION
.The surfaces of the wheels use a
different coating process than typical
aluminum alloy wheels. Do not use
aluminum alloy wheel cleaners or
abrasive cleaners to clean the wheels.
Using such cleaners could damage the
wheel surfaces.
. Do not use an automatic car wash if
the vehicle is equipped with bright
wheels. The wheel coating may be
damaged.
. Do not use a brush to wash the
wheels if the vehicle is equipped with
bright wheels. The wheel coating may be damaged.
CHROME PARTS
Clean chrome parts regularly with a non-
abrasive chrome polish to maintain the
finish.
TIRE DRESSING
INFINITI does not recommend the use of tire
dressings. Tire manufacturers apply a coat-
ing 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
coating 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
remove).
. Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is
completely removed from the tire tread/
grooves. .
Allow the tire dressing to dry as recom-
mended by tire dressing manufacturer.

8-2Do-it-yourself
When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
.Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the
vehicle from moving. Move the shift
lever to P (Park).
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. Never connect or disconnect the
battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.
. If you must work with the engine
running, 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 when-
ever you work on your vehicle.
. If you must run the engine in an
enclosed 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
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
. On gasoline engine models, the fuel
filter or fuel lines should be serviced
because the fuel lines are under high
pressure even when the engine is off. It is recommended you visit an
INFINITI retailer for this service.
CAUTION
.
Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
. Avoid direct contact with used en-
gine oil and coolant. Improperly dis-
posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items which
are relatively easy for an owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-34).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and could
affect your warranty coverage. If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.
MAINTENANCE PRECAUTIONS

SDI1729
Cargo light
SDI2032
Vanity mirror lightIf you have a flat tire, see “Flat tire” (P.6-3).
TIRE PRESSURE
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 CHECK TIRE PRESSURE
warning appears in the vehicle information
display, one or more of your tires is sig-
nificantly under-inflated.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not detect
a sudden drop in tire pressure (for example, a
flat tire while driving).
For more details, see “Low tire pressure
warning light” (P.2-15), “Tire Pressure Mon-
itoring System (TPMS)” (P.5-5) and “Tire
Pressure Monitoring System (TPMS) ” (P.6-
3).
Tire inflation pressure
Check the pressure of the tires (in-
cluding the spare) often and always
prior to long distance trips. The
recommended tire pressure specifica-
tions are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure” heading. The Tire
and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
.
Most tires naturally lose air over
time.
. Tires can lose air suddenly when
driven over potholes or other ob-
jects or if the vehicle strikes a curb
while parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle
has been parked for 3 or more hours,
or driven less than 1 mile (1.6 km) at
moderate speeds.
