6-18In 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
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 surface.
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

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 weath-
ered appearance before re-applying wax.
It is recommended that you visit a NISSAN
dealer to assist you in choosing the proper
product.
• Wax your vehicle only af ter a thoroughwashing. 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.
Machine compounding or aggressive pol-
ishing on a base coat/clear coat paint fin-
ish 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 last-
ing damage or staining. Special cleaning
products are available at a NISSAN dealer
or any automotive accessory store. It is
recommended that you visit a NISSAN
dealer for these products.
UNDERBODY
In areas where road salt is used in winter, it
is necessary to clean the underbody regu-
larly in order to prevent dirt and salt from
building up and causing the acceleration of
corrosion on the underbody and suspen-
sion. Before the winter period and again in
the spring, the underseal must be checked
and, if necessary, re-treated.
GLASS
When cleaning the rear window, it may be
easier to clean if the high-mounted stop
light is removed first.
Be careful when removing the high-
mounted stop light to reduce the risk of
damaging the high-mounted stop light
wires.
To remove the high-mounted stop light:
1. Push downward on the plastic shelf around the stop light
O1,liftupwardson
the stop light, releasing it from the shelf
O2.
LAI2116
Appearance and care7-3

2. Once it is released from the shelf, gentlypull the stop light towards the rear seat-
back
O3.
The high-mounted stop light must be
properly reinstalled before driving your
vehicle.
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.
To reinstall the high-mounted stop light,
reverse steps
O3, thenO2.
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 defog-
ger 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
remove).
• 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
manufacturer.

stall the oil filler cap securely.
For additional information about drain and
refill capacity, see “Recommended fluids/
lubricants and capacities” (P. 10-2). The
drain and refill capacity depends on the oil
temperature and drain time. Use these
specifications for reference only. Always use the dipstick to determine the proper
amount of oil in the engine.
10. Start the engine and check for leakage
around the drain plug and the oil filter.
Correct as required. Turn the engine off
and wait more than 15 minutes. Check
the oil level with the dipstick. Add en-
gine oil if necessary.
Af ter the operation
1. Reinstall undercover in reverse order ofremoval.
