7-6Appearance and care
.Use only genuine NISSAN floor
mats or equivalent floor mats
that are specifically designed for
use in your vehicle model and
model year.
. Properly position the mats in the
floorwell using the floor mat po-
sitioning hooks. See “Floor mat
installation” (P.7-6).
. Make sure the floor mat does not
interfere with pedal operation.
. Periodically check the floor mats
to make sure they are properly
installed.
. After cleaning the vehicle interior,
check the floor mats to make
sure they are properly installed.
The use of genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular clean-
ing and replaced if they become exces-
sively worn.

Floor mat installation
Your vehicle is equipped with floor mat
positioning hook(s). The number and
shape of the floor mat positioning hooks
for each seating position varies depend-
ing on the vehicle.
When installing genuine NISSAN floor
mats, follow the installation instructions
provided with the floor mat and the
following:
1. Position the floor mat in the floorwell so that the mat grommet holes are
aligned with the hook(s).
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is properly positioned.
3. Make sure the floor mat does not interfere with pedal operation. With
the ignition in the OFF position and
the shift lever in the P (Park) position,
fully apply and release all pedals. The
floor mat must not interfere with
pedal operation or prevent the pedal
from returning to its normal position.
It is recommended you see a NISSAN
dealer for details about installing the
floor mats in your vehicle.

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 precau-
tions which should be closely observed.
WARNING
.Park the vehicle on a level sur-
face, 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
performing any parts replace-
ment or repairs.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or auto-
matic transmission related com-
ponent harnesses disconnected
while the ignition switch is in the
ON position.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection
whenever you work on your ve-
hicle.
. 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
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid
injury, always disconnect the ne-
gative battery cable before work-
ing near the fan. .
Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
you visit a NISSAN dealer for
service of the fuel 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
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local 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 NISSAN Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-35).)
You should be aware that incomplete or
improper servicing may result in operat-
ing difficulties or excessive emissions, and
MAINTENANCE PRECAUTIONS

CAUTION
.Do not overfill.
. Use Genuine NISSAN PSF or
equivalent. For further brake fluid specification infor-
mation, see “Capacities and recom-
mended fluids/lubricants” (P.10-2).
WARNING
.
Use only new fluid from a sealed
container. Old, inferior or con-
taminated fluid may damage the
brake system. The use of impro-
per fluids can damage the brake
system and affect the vehicle’s
stopping ability.
. Be sure to clean the filler cap
before removing.
. Brake fluid is poisonous and
should be stored carefully in
marked containers out of the
reach of children.
CAUTION
.Do not add brake fluid with the
ignition switch in the ON position
or the engine running. Doing so
could make the brake fluid over-
fill when the ignition switch is
turned off. .
Do not spill the fluid on painted
surfaces. This will damage the
paint. If fluid is spilled, wash the
surface with water.

JUMP STARTING
If jump starting is necessary, see “Jump
starting” (P.6-12). If the engine does not
start by jump starting, the battery may
have to be replaced. It is recommended
you visit a NISSAN dealer for this service.CAUTION
.Do not ground accessories di-
rectly to the battery terminal.
Doing so will bypass the variable
voltage control system and the
vehicle battery may not charge
completely.
. Use electrical accessories with
the engine running to avoid dis-
charging the vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.

If replacement is required, it is recom-
mended you visit a NISSAN dealer for this
service.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-
tipped spark plugs as frequently as the
conventional type spark plugs since they
will last much longer. Follow the main-
tenance schedule shown in the “9. Main-
tenance and schedules” section, but do
not reuse them by cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.
