PRECAUTIONS ON CRUISE
CONTROL
cIf the cruise control system malfunctions, it
cancels automatically. The SET indicator light
in the instrument panel then blinks to warn the
driver.
cIf the SET indicator light blinks, turn the cruise
control main switch off and have the system
checked by a NISSAN dealer.cThe SET indicator light may blink when the
cruise control main switch is turned ON while
pushing the RES/ACCEL, COAST/SET, or
CANCEL switch (located on the steering
wheel) . To properly set the cruise control sys-
tem, use the following procedures.
WARNING
Do not use the cruise control when driving
under the following conditions:
cWhen it is not possible to keep the
vehicle at a set speed.
cIn heavy traffic or in traffic that varies in
speed.
cOn winding or hilly roads.
cOn slippery roads (rain, snow, ice, etc.) .
cIn very windy areas.
Doing so could cause a loss of vehicle
control and result in an accident.
CAUTION
On manual transmission models, do not
shift into N (Neutral) without depressing
the clutch pedal when the cruise control is
set. Should this occur, depress the clutch
pedal and turn the main switch off imme-
diately. Failure to do so may cause engine
damage.
CRUISE CONTROL OPERATIONS
The cruise control allows driving at a speed be-
tween 25 - 90 MPH (40 - 144 km/h) without
keeping your foot on the accelerator pedal.
To turn on the cruise control,push the main
switch. The CRUISE indicator light in the instru-
ment panel comes on.
To set cruising speed,accelerate the vehicle to
the desired speed, push the COAST/SET switch
and release it. The SET indicator light in the
instrument panel comes on. Take your foot off the
accelerator pedal. Your vehicle maintains the set
speed.
cTo pass another vehicle,depress the ac-
celerator pedal. When you release the pedal,
the vehicle returns to the previously set speed.
cThe vehicle may not maintain the set speed
when going up or down steep hills. If this
happens, drive without the cruise control.

cAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
cDrive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
cAvoid unnecessary stopping and braking.
Maintain a safe distance behind other vehicles.
cUse a proper gear range which suits road
conditions. On level roads, shift into high gear
as soon as possible.
cAvoid unnecessary engine idling.
cKeep your engine tuned up.
cFollow the recommended periodic mainte-
nance schedule.
cKeep the tires inflated to the correct pressure.
Low tire pressure increases tire wear and low-
ers fuel economy.
cKeep the front wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
cAir conditioner operation lowers fuel economy.
Use the air conditioner only when necessary.
cWhen cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.cUse 4H or 4L position only when nec-
essary. Four-wheel drive operation lowers fuel
economy.
To move the transfer case lever:
: Push down on the lever to shift
: Shift without pushing down on the lever

cDo not leave the transfer control lever in
the N (Neutral) position. Otherwise, the
vehicle could roll unexpectedly even if
the manual transmission is in any gear
or the automatic transmission is in the
P (Park) position. This could result in
serious personal injury or property
damage.
cFailure to engage the transfer control
lever in 2H, 4H or 4L could result in the
vehicle moving unexpectedly, which
could cause serious personal injury or
property damage.
CAUTION
Do not drive on dry hard surface roads in
four-wheel drive. Driving on dry hard sur-
faces in 4H or 4L may cause unnecessary
noise, tire wear, and increased fuel con-
sumption. NISSAN recommends driving in
the 2H position under these conditions.
2H— (2WD, high range) Only the rear wheels
are driven. Use for driving under the same condi-
tions as standard 2WD vehicles or state dyna-
mometer I/M testing.
4H— (4WD, high range) Four wheels are driven.
Use when driving on roads where it is difficult todrive in the 2H position (for example, driving at
normal speeds on snow covered, icy, wet, muddy
or sandy roads) .
The 4H position provides greater power and
traction. Avoid excessive speed as it will cause
increased fuel consumption, higher oil tempera-
ture and could damage drivetrain components.
Speed over 50 MPH (80 km/h) in 4H are not
recommended.
4L— (4WD, low range) Four wheels are driven.
Use when climbing or descending steep hills, or
during hard driving in sand, mud or deep snow.
The 4L position provides maximum power and
traction. Avoid raising vehicle speed excessively,
as the maximum speed is approximately 30 MPH
(48 km/h) .
N— No wheels are driven. Always keep the
transfer lever out of the N (Neutral) position. Shift
the lever quickly and smoothly when moving
across the N (Neutral) position with the vehicle
stopped.AUTO-LOCK FREE-
RUNNING HUBS
The auto-lock free-running hub is designed to
allow for automatic four-wheel drive engagement
when the shift lever is moved to the 4H or 4L
position. Follow these operational cautions:
CAUTION
cThe auto-locking hubs will make a
clicking noise when engaging and dis-
engaging. This is normal.

cAccelerating quickly from a stop after
shifting from two-wheel drive to four-
wheel drive may not allow engagement
of the auto-locking free-running hubs
and may cause a clattering noise. If this
occurs, release the accelerator pedal to
reduce the engine speed or stop the
vehicle. Continued use of the vehicle
with this noise may damage the hub
lock.
cIf the auto-locking hubs make a clatter-
ing noise after shifting from four-wheel
drive to two-wheel drive, stop and move
the vehicle in reverse gear, in a straight
line, about 7 to 10 feet (2 to 3 m) .
cUnder extremely cold conditions [below
5°F (-15°C)], the front axle shafts may
rotate even with the transfer lever in the
2H position. If this occurs, the auto-
locking hubs may make a clattering
noise. To avoid this, drive first in four-
wheel drive to warm up the vehicle and
differential gear oil. Then, shift to two-
wheel drive.
cIn cold weather, it may be necessary to
reduce speed or stop the vehicle in or-
der to shift from two-wheel drive to
four-wheel drive.cWhen shifting into or out of four-wheel
drive while driving, do not stop shift
lever movement midway. An incomplete
shift may cause a clattering noise from
the auto-locking hubs. Continued use
of the vehicle with this noise may dam-
age the hub lock. Drive in four-wheel
drive to stop the noise. Shift to two-
wheel drive as described.
For Automatic transmission models:
When moving the transfer lever from 4H or 4L to
4L or 4H, you must always move it quickly
through the N position. If you are slow to shift, the
engine idle speed will allow the transfer gears to
speed up and gear clashing will occur.
Do not move the transfer lever from 4H or 4L to
4L or 4H, from 2H to 4L and from 4L to 2H with
the engine turned off. Otherwise, you may have
difficulty in moving the transfer lever to the de-
sired position.
Do not leave the transfer lever in the N position
with the engine running. Stopping with the trans-
fer case in the N position may cause gear grind-
ing when selecting another gear. Changing the
transfer case gear quickly and smoothly will elimi-
nate this.

2.Manual transmission models:
Place the shift lever in the R (Reverse) posi-
tion. When parking on an uphill grade, place
the shift lever in 1st gear.
Automatic transmission models:
Move the shift selector lever to the P (Park)
position.
3. To help prevent the vehicle from rolling into
traffic when parked on an incline, it is a good
practice to turn the wheels as illustrated.
cHEADED DOWNHILL WITH CURB:
s1
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel gen-
tly touches the curb.
cHEADED UPHILL WITH CURB:
s2
Turn the wheels away from the curb and move
the vehicle back until the curb side wheel
gently touches the curb.
cHEADED UPHILL OR DOWNHILL, NO
CURB:
s3
Turn the wheels toward the side of the road so
the vehicle will move away from the center of
the road if it moves.
4. Turn the ignition key to the LOCK position
and remove the key.The power assisted steering is designed to use a
hydraulic pump, driven by the engine, to assist
steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, especially
in sharp turns and at low speeds.
WARNING
If the engine is not running or is turned off
while driving, the power assist for the
steering will not work. Steering will be
much harder to operate.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake linings and pads faster, and reduce gas
mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.

WARNING
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
cIf the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
ANTI-LOCK BRAKE SYSTEM (ABS)
The anti-lock brake system controls the brakes at
each wheel so the wheels do not lock when
braking abruptly or when braking on slippery sur-
faces. The system detects the rotation speed at
each wheel and varies the brake fluid pressure toprevent each wheel from locking and sliding. By
preventing wheel lockup, the system helps the
driver maintain steering control and helps to mini-
mize swerving and spinning on slippery surfaces.
Using the system (4-wheel ABS)
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Normal operation
The anti-lock brake system does not operate at
speeds below3-6MPH(5-10km/h) . (The
speeds vary according to road conditions.)
When driving, the anti-lock brake system con-
trols the wheels so they will not lock when brak-
ing abruptly or when braking on a slippery road.
Thus, difficult steering and swerving of the ve-
hicle due to locked wheels is minimized. The
system detects the wheel rotation rate and elec-
tronically controls the pressure applied to each
brake. Slight vibration on the brake pedal accom-
panied by noise usually occurs while the ABS
system is operating. Such vibration and noise
encountered during abrupt braking is not a prob-
lem, but indicates that the system is functioningproperly. However, the pulsation may indicate
that road conditions are hazardous and extra care
is required while driving.
Self-test feature
The anti-lock brake system consists of electronic
sensors and hydraulic solenoids controlled by a
computer. The computer has a built-in diagnostic
feature that tests the system each time you start
the engine and move the vehicle at a low speed in
forward or reverse. When the self-test occurs,
you may hear a ‘‘clunk’’ noise and/or feel a pulsa-
tion in the brake pedal. This is normal and is not
an indication of any malfunction. If the computer
senses any malfunction, it switches the anti-lock
brake system off and turns on the ABS brake
warning light on the instrument panel. The brake
system then operates normally, but without anti-
lock assistance.
If a malfunction occurs in the system, the anti-
lock function will not operate, but the standard
vehicle brake system will continue to operate
normally. The ABS brake warning light will then
come on.
If the light comes on during the self-test or while
driving, take the vehicle to a NISSAN dealer for
repair.

WARNING
cThe anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with the anti-lock brake
system. Stopping distances may also
be longer on rough, gravel or snow cov-
ered roads, or if you are using tire
chains. Tire type and condition may also
affect braking effectiveness. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the re-
sponsibility for safety of self and others
rests in the hands of the driver.
cTire type and condition of tires may also
affect braking effectiveness.
cWhen replacing tires, install the speci-
fied size of tires on all four wheels.cWhen installing a spare tire, make sure
it is the proper size and type as speci-
fied on the tire placard. For tire placard
location information, refer to “Tire plac-
ard” in the “Technical and consumer
information” section of this manual.
cRefer to “Wheels and tires” in the
“Maintenance and do-it-yourself” sec-
tion of this manual.When driving on slippery surfaces or suddenly
avoiding obstacles on roads, the vehicle might
swerve or slip. With the Vehicle Dynamic Control
(VDC) system, sensors detect these movements
and control the braking and engine output to help
improve vehicle stability while driving.
cWhen the vehicle dynamic control system is
operating, the slip indicator in the instrument
panel blinks.
cWhen only the traction control system portion
of the vehicle dynamic control system is oper-
ating, the slip indicator will also blink.
cIf the slip indicator blinks, the vehicle is under
slippery conditions. Be sure to drive carefully.
See “Slip indicator light”, and “Vehicle dy-
namic control off indicator light” in the “Instru-
ments and controls” section.
cIndicator light
If malfunction occurs in the system, the
andindicator lights come on in the in-
strument panel.
As long as these warning lights are on, the
traction control function is canceled.
The VDC system uses a Brake Limited Slip Dif-
ferential (LSD) system to improve vehicle trac-
tion. The brake LSD system works when one of
the driving wheels is spinning on a slippery sur-
face. The brake LSD system brakes the spinning
