∙ 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. (For
additional information, refer to “Flat
tire” in the “In case of emergency” section
for changing a flat tire.) ∙ When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is re-
placed, tire pressure will not be indicated,
the TPMS will not function and the low
tire pressure warning light will flash for
approximately 1 minute. The light will re-
main 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 this
service.
∙ 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.
CAUTION
∙ The TPMS may not function properlywhen the wheels are equipped with tire
chains or the wheels are buried in snow.
∙ Do not place metalized film or any metal parts (antenna, etc.) on the windows.
This may cause poor reception of the sig-
nals from the tire pressure sensors, and
the TPMS will not function properly. Some devices and transmitters may tempo-
rarily interfere with the operation of the
TPMS and cause the low tire pressure warn-
ing light to illuminate.
Some examples are:
∙ Facilities or electric devices using similar radio frequencies are near the vehicle.
∙ If a transmitter set to similar frequencies is being used in or near the vehicle.
∙ If a computer (or similar equipment) or a DC/AC converter is being used in or near
the vehicle.
The low tire pressure warning light may illu-
minate in the following cases: ∙ If the vehicle is equipped with a wheel and tire without TPMS.
∙ If the TPMS has been replaced and the ID has not been registered.
∙ If the wheel is not originally specified by INFINITI.

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 apunctured 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 puncturedrun-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.
6-4In case of emergency

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 dam- age 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 sur- face.
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, 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 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 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.
∙ Wax your vehicle only after a thorough washing. Follow the instructions supplied
with the wax.
∙ Do not use a wax containing any abra- sives, cutting compounds or cleaners that
may damage the vehicle finish.
CLEANING EXTERIOR
7-2Appearance and care

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 permanent discoloration when they con-
tact vehicle interior surfaces. Place the air
freshener in a location that allows it to
hang free and not contact an interior sur-
face.
∙ Liquid-type air fresheners typically clip on the vents. These products can cause im-
mediate 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.
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.

Appearance and care7-5

CAUTION
∙ NEVER remove dirt, sand or other debrisfrom 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 fend-
ers.
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.
