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.
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.
.Wax your vehicle only after a thorough
washing. Follow the instructions sup-
plied with the wax.
CLEANING EXTERIOR

.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 duringwinter.
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 maybe 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 movingparts.
.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.
.Because the fuel lines are under high
pressure even when the engine is off,
it is recommended you visit an
INFINITI retailer for service of thefuel filter or fuel lines.
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.10-24).)
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.

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufacturer
for the possible influences before use.
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 “Tire Pressure Low - Add
Air” warning appears in the vehicle informa-
tion display, one or more of your tires is
significantly 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

TIRE LABELING
Federal law requires tire manufac-
turers to place standardized informa-
tion on the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.
SDI1606
Example
Tire size (example: P215/60R16
94H)
1. P: The “P” indicates the tire is
designed for passenger vehicles.
(Not all tires have this informa-
tion.)
2. Three-digit number (215): This
number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge.
3. Two-digit number (60): This num-
ber, known as the aspect ratio,
gives the tire’s ratio of height towidth.
4. R: The “R” stands for radial.
F: The “F” after “R” indicates Self-
Supporting type run-flat tire.
5. Two-digit number (16): This num-
ber is the wheel or rim diameter in
inches.
6. Two- or three-digit number (94):
This number is the tire’s load index.
It is a measurement of how much
weight each tire can support. You
may not find this information on all
tires because it is not required by
law.
7. H: Tire speed rating. You should
not drive the vehicle faster than
the tire speed rating.

TYPES OF TIRES
WARNING
.When changing or replacing tires, be
sure all four tires are of the same type
(Example: Summer, All Season or
Snow) and construction. An INFINITI
retailer may be able to help you with
information about tire type, size,
speed rating and availability.
.Replacement tires may have a lower
speed rating than the factory
equipped tires, and may not match
the potential maximum vehicle speed.
Never exceed the maximum speed
rating of the tire.
.Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
.For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety
Information” (Canada) in the War-
ranty Information Booklet.
All season tires
INFINITI specifies all season tires on some
models to provide good performance allyear, including snowy and icy road condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S (Mud and Snow) on
the tire sidewall. Snow tires have better
snow traction than All Season tires and may
be more appropriate in some areas.
Summer tires
INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is
substantially reduced in snow and ice. Sum-
mer tires do not have the tire traction rating
M&S on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, INFINITI recommends the
use of SNOW tires or ALL SEASON tires on
all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires, they must be thesame size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires. Skid and
traction capabilities of studded snow tires,
on wet or dry surfaces, may be poorer than
that of non-studded snow tires.
Run-flat tires
Your vehicle is equipped with run-flat tires.
You can continue driving to a safe location
even if they are punctured. Always use run-
flat tires of the specified size on all four
wheels. Mixing tire sizes or construction may
reduce vehicle handling stability. If neces-
sary, contact an INFINITI retailer for assis-
tance.
Frequently check the tire pressure and adjust
pressure of each tire properly. The tire
pressure can be also checked in the vehicle
information display.
It can be difficult to tell if a run-flat tire is
under-inflated or flat. Check the tire pres-
sures as described earlier in this section. If
the tire becomes under-inflated while driv-
ing, the low tire pressure warning light will
illuminate. If the tire becomes flat while
driving, the low tire pressure warning light

TIRE CHAINS
CAUTION
Tire chains/cables should not be in-
stalled on P255/40RF19,
P255/35R20, 255/35R20 and
275/30R20 tires. Doing so will cause
damage to the vehicle. If you plan to use
tire chains/cables, you should install
245/40RF19 run-flat tires or
245/40R19 non run-flat tires on your
vehicle.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size
for the tires on your vehicle and are installed
according to the chain manufacturer’s sug-
gestions.Use only SAE Class S chains.Class
“S” chains are used on vehicles with re-
stricted tire to vehicle clearance. Vehicles
that can use Class “S” chains are designed to
meet the SAE standard minimum clearances
between the tire and the closest vehicle
suspension or body component required to
accommodate the use of a winter traction
device (tire chains or cables). The minimum
clearances are determined using the factory
equipped tire size. Other types may damageyour vehicle. Use chain tensioners when
recommended by the tire chain manufac-
turer to ensure a tight fit. Loose end links of
the tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire (if so equipped). Never
install tire chains on a punctured run-flat tire
(if so equipped), as this could damage your
vehicle.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.
SDI1662
CHANGING WHEELS AND TIRES
Tire rotation (models equipped with
same size tires on all wheels)
INFINITI recommends rotating the
tires at the specified interval shown
in the maintenance schedule. (See the
"9. Maintenance and schedules" sec-
tion. For tire replacing procedure, see
“Jacking up the vehicle and replacing
tires” (P.8-38).)
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
