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
vehicle as soon as you can:
• Af ter a rainfall to prevent possible dam-age from acid rain.
• Af ter 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 ve-
hicle 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 sur-
face when putting on or removing the
body cover.
WASHING
Wash dirt off with a wet sponge and plenty
of water. Clean the vehicle thoroughly us-
ing 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 di-
rectly 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 vehicle. Use of
high-pressure washers over 1,200 psi
(8,274 kPa) can result in damage to or
removal of paint or graphics. Avoid
using a high-pressure washer closer
than 12 inches (30 cm) to the vehicle.
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 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 func-
tion 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 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 edges, seams and folds on the
doors, hatches and hood are particularly
vulnerable to the effects of road salt. There-
fore, 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.
CLEANING EXTERIOR
7-2Appearance and care

The high-mounted stop light must be
properly reinstalled before driving your ve-
hicle.
Use glass cleaner to remove smoke and
dust film from the glass surfaces. It is nor-
mal for glass to become coated with a film
af ter the vehicle is parked in the hot sun.
Glass cleaner and a sof t 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
disinfectant cleaners. They could dam-
age the electrical conductors, radio an-
tenna elements or rear window de-
froster elements.
ALUMINUM ALLOY WHEELS (if so
equipped)
Wash the wheels regularly with a sponge
dampened in a mild soap solution, espe-
cially 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
ambient temperature.
• Rinse the wheel to completely re-
move the cleaner within 15 minutes
af ter the cleaner is applied.
CHROME PARTS
Clean all chrome parts regularly with a
non-abrasive chrome polish to maintain
the finish.
TIRE DRESSINGS
NISSAN does not recommend the use of
tire dressings. Tire manufacturers apply a
coating to the tires to help reduce discolor-
ation of the rubber. If a tire dressing is ap-
plied to the tires, it may react with the coat-
ing 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
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 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 the tire dressing manufac-
turer.

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 fol-
lowing 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 ve-
hicle from moving. For manual trans-
mission models, move the shif t lever
to N (Neutral). For CVT models, move
the shif t lever to P (Park).
• Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing any parts replacement or repairs.
• 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 when-
ever 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 nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
• Because the fuel lines on gasoline
engine models are under high pres-
sure even when the engine is off, it is
recommended that you visit a
NISSAN dealer for service of the fuel
filter or fuel lines.
• Your vehicle is equipped with an au-
tomatic 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.
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. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
• Never leave the engine or the trans-
mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner's Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

If you have a flat tire, refer to “Flat tire” in
the “In case of emergency ” section of
this manual.
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 manufac-
turer for the possible influences before
use.
This vehicle is equipped with the Tire Pres-
sure Monitoring System (TPMS). It monitors
tire pressure of all tires except the spare.
When the low tire pressure warning light is
lit and warning is displayed in the odom-
eter, or the “Tire Pressure Low — Add Air”
appears in the vehicle information display,
one or more of your tires is significantly
under-inflated.
The TPMS will activate only when the ve-
hicle 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 additional information, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section, “Tire Pressure Moni-
toring System (TPMS)” in the “Starting and
driving” section, and “Flat tire” in the “In case
of emergency” section of this manual.Tire inflation pressure
Check the tire pressures (including
the spare) of ten and always prior to
long distance trips. The recom-
mended tire pressure specifications
are shown on the F.M.V.S.S./C.M.V.S.S.
certification label or the Tire and
Loading Information label under the
“Cold Tire Pressure” heading. The Tire
and Loading Information label is af-
fixed 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 af ter the
vehicle has been parked for 3 or
more hours, or driven less than 1 mile
(1.6 km) at moderate speeds.
The TPMS with Easy-Fill Tire Alert (if
so equipped) provides visual and au-
dible signals outside the vehicle for
inflating tires to the recommended
COLD tire pressure. For additional in-
formation, refer to “TPMS with Easy-
Fill Tire Alert” in the “Starting and driv-
ing” section of this manual.
Incorrect tire pressure, including
under inflation, may adversely af-
fect tire life and vehicle handling.
WHEELS AND TIRES
8-28Do-it-yourself

O1Tire size (example: P215/65R15
95H)
1. P: The “P” indicates the tire is de- signed for passenger vehicles (not
all tires have this information).
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 (65): This num-
ber, known as the aspect ratio,
gives the tire's ratio of height to
width.
4. R: The “R” stands for radial.
5. Two-digit number (15): This num- ber is the wheel or rim diameter in
inches. 6. Two- or three-digit number (95):
This number is the tire's load in-
dex. It is a measurement of how
much weight each tire can sup-
port. You may not find this infor-
mation 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.
WDI0395
Example
8-32Do-it-yourself

O6Term of “tubeless” or “tube type”
Indicates whether the tire requires
an inner tube (“tube type”) or not
(“tubeless”).
O7The word “radial”
The word “radial” is shown if the tire
has radial structure.
O8Manufacturer or brand name
Manufacturer or brand name is
shown.
Other Tire-related Terminology
In addition to the many terms that
are defined throughout this section,
Intended Outboard Sidewall is (1) the
sidewall that contains a whitewall,
bears white lettering or bears
manufacturer, brand, and/or model
name molding that is higher or
deeper than the same molding on
the other sidewall of the tire, or (2)
the outward facing sidewall of an
asymmetrical tire that has a particu- lar side that must always face out-
ward when mounted on a vehicle.
TYPES OF TIRES
WARNING
• When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow)
and construction. A NISSAN dealer
may be able to help you with infor-
mation 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 origi-
nally specified by NISSAN could af-
fect the proper operation of the low
tire pressure warning system. •
Always use tires of the same type,
size, brand, construction and tread
pattern on all four wheels. Failure to
do so may result in a circumference
difference between tires on the front
and rear axles which can cause the
Vehicle Dynamic Control (VDC) sys-
tem to malfunction resulting in per-
sonal injury or death, excessive tire
wear and may damage the transmis-
sion and differential gears.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
All season tires
NISSAN specifies All Season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S on the tire sidewall.
Snow tires have better snow traction than
All Season tires and may be more appropri-
ate in some areas.
8-34Do-it-yourself

Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer 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, NISSAN 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 rat-
ing to the original equipment tires. If you do
not, it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires have lower speed rat-
ings 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 the
same size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads, stud-
ded 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.
TIRE CHAINS
CAUTION
Tire chains/cables should not be in-
stalled on 215/50R17 and 215/45R18
size tires. Installation of the tire chains/
cables on 215/50R17 and 215/45R18
size tires will cause damage to the ve-
hicle. If you plan to use tire chains/
cables, you should install 205/60R16
size tires on your vehicle.
Use of tire chains may be prohibited ac-
cording 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 manufac-
turer's suggestions. Use only SAE class “S”
chains. Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve- hicle suspension or body component re-
quired to accommodate the use of a
winter traction device (tire chains or
cables). The minimum clearances are de-
termined using the factory equipped tires.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer 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
front wheels and not on the rear wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires ev-
ery 7,500 miles (12,000 km).
For additional information on tire replacing
procedures, refer to “Flat tire” in the “In case
of emergency” section of this manual.
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.Wheel nut tightening torque:
83 f t-lb (113 N·m)
The wheel nuts must be kept tightened
to specifications at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation inter-
val.
WARNING
• Af ter rotating the tires, check and ad-
just the tire pressure.
• Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
• Do not include the spare tire in the
tire rotation.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
