5-122Starting and driving
CAUTION
.Do not drive the vehicle in the 4HI
or 4LO position on dry hard sur-
face roads. Driving on dry, hard
surfaces in 4HI or 4LO may cause
unnecessary noise, tire wear and
increased fuel consumption.
If the Four-Wheel Drive (4WD)
warning light turns on when driv-
ing on dry hard surface roads:
— in the 4HI position, shift the
4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmis-
sion lever to the N (Neutral)
position with the brake pedal
depressed and shift the 4WD
shift switch to AUTO.
If the 4WD warning light is still
on after the above operation,
have your vehicle checked as
soon as possible. It is recom-
mended you visit a NISSAN
dealer for this service.
. The transfer case may be da-
maged if you continue driving
with the 4WD warning light blink-
ing. See “On-pavement and off-road driving
precautions” (P.5-9) for other precautions
for offroad driving.NISSAN ALL-MODE 4WD® SYSTEM
The all mode 4WD system provides 3
positions (AUTO, 4HI and 4LO), so you
can select the desired drive mode accord-
ing to the driving conditions.
4WD shift procedure:

The 4WD shift switch is used to select the
4WD mode depending on the driving
conditions. There are 3 types of drive
modes available, AUTO, 4HI and 4LO.
The 4WD shift switch electronically con-
trols the transfer case operation. Rotate
the switch to move between each mode,
AUTO, 4H and 4L.
You must depress the 4WD shift switch
to select 4L, and the vehicle MUST be
stationary and the shift lever in the N
(Neutral) position when changing into
or out of 4L.
WARNING
.When parking, apply the parking
brake before stopping the engine
and make sure that the 4WD shift
indicator is on and the ATP warn-
ing light turns off. Otherwise, the
vehicle could unexpectedly move
even if the automatic transmis-
sion is in the P (Park) position.
. The 4LO and 4HI indicators must
stop blinking and the 4LO or 4HI
indicator must remain illumi-
nated or turn off before shifting
the transmission into gear. If the
shift lever is shifted from the N
(Neutral) position to any other gear while the 4LO and 4HI in-
dicators are blinking alternately,
the vehicle may move unexpect-
edly.
CAUTION
.
Never shift the 4WD shift switch
between 4L and 4H while driving.
. The 4HI position provides greater
traction. Avoid excessive speed,
as it will cause increased fuel
consumption and higher oil tem-
peratures, and could damage dri-
vetrain component. Speeds over
62 MPH (100 km/h) in 4HI is not
recommended.
. The 4LO position provides max-
imum traction. Avoid raising ve-
hicle speed excessively, as the
maximum speed is approxi-
mately 31 MPH (50 km/h).
. When driving straight, shift the
4WD shift switch to the AUTO or
4H position. Do not move the 4WD
shift switch when making a turn
or reversing.
. Do not shift the 4WD shift switch
(between AUTO and 4H) while
driving on steep downhill grades. Use the engine brake and low
automatic transmission gears
for engine braking.
. Do not operate the 4WD shift
switch (between AUTO and 4H)
with the rear wheels spinning.
. Do not drive on dry hard surface
roads in the 4HI or 4LO position.
Driving on dry hard surfaces in
4HI or 4LO may cause unneces-
sary noise and tire wear. NISSAN
recommends driving in the AUTO
position under these conditions.
. The 4WD transfer case may not
be shifted between 4HI and 4LO
at low ambient temperatures and
the 4LO and 4HI indicators may
blink even when the 4WD shift
switch is shifted. After driving for
a while you can change the 4WD
shift switch between 4H and 4L.
When driving on rough roads,
. Drive carefully according to the road
surface conditions.
When the vehicle is stuck,
. Place stones or wooden blocks under
the tires to free the vehicle.
. Set the 4WD shift switch to 4H or 4L.

will either remain illuminated or blink.
If the 4WD warning light comes on, the
4WD shift indicator turns off.
High-temperature transfer case oil makes
the 4WD warning light blink rapidly (about
twice per second). If the warning light
blinks rapidly during operation, stop the
vehicle in a safe place immediately. Then
if the light turns off after a while, you can
continue driving.
A large difference between the diameters
of front and rear wheels will make the
4WD warning light blink slowly (about
once per two seconds). Change the 4WD
shift switch to AUTO and do not drive fast.
CAUTION
.If the 4WD warning light comes
on or blinks slowly during opera-
tion or rapidly after stopping the
vehicle for a while, have your
vehicle checked as soon as pos-
sible. It is recommended you visit
a NISSAN dealer for this service.
. Shifting between 4HI and 4LO is
not recommended when the 4WD
warning light turns on.
. When the 4WD warning light
comes on, the 2WD mode may be engaged even if the 4WD shift
switch is in AUTO or 4H. Be
especially careful when driving. If
corresponding parts are malfunc-
tioning, the 4WD mode will not be
engaged even if the 4WD shift
switch is shifted.
. Do not drive the vehicle in the 4HI
or 4LO position on dry hard sur-
face roads. Driving on dry, hard
surfaces in 4HI or 4LO may cause
unnecessary noise, tire wear and
increased fuel consumption.
If the 4WD warning light turns on
when driving on dry hard surface
roads:
— in the AUTO or 4HI position,
shift the 4WD shift switch to
AUTO.
— in the 4LO position, stop the vehicle and shift the transmis-
sion shift lever to the N (Neu-
tral) position and shift the
4WD shift switch to AUTO.
. If the 4WD warning light is still on
after the above operation, have
your vehicle checked as soon as
possible. It is recommended you
visit a NISSAN dealer for this
service. .
The transfer case may be da-
maged if you continue driving
with the warning light blinking.

Turn the wheels toward the side of
the road so the vehicle will move away
from the center of the road if it moves.

WARNING
.The sonar system is a conveni-
ence but it is not a substitute for
proper parking. Always look
around and check that it is safe
to do so before parking. Always
move slowly.
. Read and understand the limita-
tions of the sonar system as
contained in this section. Incle-
ment weather may affect the
function of the sonar system; this
may include reduced perfor-
mance or a false activation. .
This system is not designed to
prevent contact with small or
moving objects.
. The system is designed as an aid
to the driver in detecting large
stationary objects to help avoid
damaging the vehicle. The sys-
tem will not detect small objects
below the bumper, and may not
detect objects that are too close

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
damage 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, lu-
kewarm (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 components, caus-
ing 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 detergents, 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 da-
maged. .
Lock all doors before going
through automatic car wash.
Locking doors helps prevent
fuel-filler door from opening and
becoming 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.
A NISSAN dealer can assist you in choos-
ing the proper product.
CLEANING EXTERIOR

7-8Appearance and care
Temperature
A temperature increase will accelerate
the rate of corrosion to those parts which
are not well ventilated.
Air pollution
Industrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use will accelerate the corrosion process.
Road salt will also accelerate the disin-
tegration of paint surfaces.
TO PROTECT YOUR VEHICLE FROM
CORROSION
.Wash and wax your vehicle often to
keep the vehicle clean.
. Always check for minor damage to the
paint and repair it as soon as possible.
. Keep drain holes at the bottom of the
doors open to avoid water accumula-
tion.
. Check the underbody for accumula-
tion of sand, dirt or salt. If present,
wash with water as soon as possible.
CAUTION
.NEVER remove dirt, sand or other
debris from the passenger com-
partment by washing it out with a
hose. Remove dirt with a vacuum cleaner.
. Never allow water or other liquids
to come in contact with electronic
components inside the vehicle as
this may damage them.
Chemicals used for road surface deicing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor
pan and fenders.
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 you consult a
NISSAN dealer.

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.
