ACCEL set switch. Each time you do this,
the set speed will increase by about 1 MPH
(1.6 km/h).
To reset at a slower cruising speed,follow
either of these three methods:
a) Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
COAST/SET switch and release it.
b) Push and hold the COAST/SET switch.
Release the switch when the vehicle slows
down to the desired speed.
c) Push, then quickly release the COAST/
SET switch. Each time you do this, the set
speed will decrease by about 1 MPH (1.6
km/h).
To resume the preset speed,push and re-
lease the resume set switch. The vehicle will
resume the last set cruising speed when the
vehicle speed is over 30 MPH (48 km/h).
PrecautionsIThe cruise indicator may sometimes blink
when the cruise control switch (Main
switch) is turned ON while pushing the
RES/ACCEL switch or COAST/SET switch
or CANCEL switch (located on the steering
wheel). To properly set the cruise control
system perform the steps above in theorder indicated. (This is a fail-safe mode.
Turn the main switch OFF and turn it ON
again without pushing the set switch to
return to normal operation.)
IIf the cruise control system malfunctions, it
will cancel automatically. The cruise indica-
tor in the meter assembly will then blink to
warn the driver.
IWhen the cruise indicator blinks, turn the
cruise control switch (Main switch) OFF and
have the system checked by your NISSAN
dealer.During the first 1,000 miles (1,600 km), follow
these recommendations for the future reliabil-
ity and economy of your new vehicle. Failure to
follow these recommendations may result in
vehicle damage or shortened engine life.
IDo not run the engine over 4,000 rpm.
Do not drive over the following speed limits:
Two wheel drive models:
Four wheel drive models
(2H position):
55 MPH (90 km/h)
Four wheel drive models
(4H position):
50 MPH (80 km/h)
Four wheel drive models
(4L position):
30 MPH (50 km/h)
IDo not accelerate hard in top gear.
IAvoid quick starts and full acceleration.
IAvoid hard stops as much as possible.
I
For the first 300 miles (500 km), it is rec-
ommended that you drive in the two wheel
drive (2H) position.
IDo not tow a trailer for the first 500 miles
(800 km).

IAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
IDrive at moderate speeds on the highway.
Driving at high speed will lower fuel
economy.
IAvoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
IUse a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
IAvoid unnecessary engine idling.IKeep your engine tuned up.
IFollow the recommended periodic mainte-
nance schedule.
IKeep the tires inflated at the correct pres-
sure. Low pressure will increase tire wear
and waste fuel.
IKeep the front wheels in correct alignment.
Improper alignment will cause increased
tire wear and lower fuel economy.
IAir conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.
IWhen cruising at highway speeds, it is
more economical to use the air conditioner
and leave the windows closed to reduce
drag.
I
Use 4H or 4L position only when neces-
sary. Four wheel drive operation lowers fuel
economy.

INever leave children unattended in
the vehicle.
The power assisted steering is designed to
use a hydraulic pump, driven by the engine, to
assist steering.
If the engine stops or drive belt breaks, you will
still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns or at low speeds.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 develops a problem, you
will still have braking at two wheels.
Vacuum assisted brake
The brake booster aids braking by using en-
gine 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
the stopping distance will be longer.
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 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.
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.

brakes from overheating, before going down a

slope or long grade, reduce speed and down-
shift to a lower gear.IWhile driving on a slippery surface,
be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.
IIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.ANTI-LOCK BRAKE SYSTEM (ABS)The anti-lock brake system controls the brakes
at each wheel so the wheels will not lock when
braking abruptly or when braking on slippery
surfaces. The system detects the rotation
speed at each wheel and varies the brake fluid
pressure to prevent each wheel from locking
and sliding. By preventing wheel lockup, the
system helps the driver maintain steering con-
trol and helps to minimize swerving and spin-
ning on slippery surfaces.
Using the systemDepress the brake pedal and hold it down.Do not pump the brake pedal. Doing so
may result in increased stopping
distances.Normal operationThe anti-lock brake system will not operate at
speeds below 3 to 6 MPH (5 to 10 km/h) to
completely stop the vehicle. (The speeds will
vary according to road conditions.) When the
anti-lock system senses that one or more
wheels are close to locking up, the actuator
(under the hood) rapidly applies and releases
hydraulic pressure (like pumping the brakes
very quickly). While the actuator is working,
you may feel a pulsation in the brake pedal
and hear a noise or vibration from the actuator
under the hood. This is normal and indicates
that the anti-lock system is working properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.
If a tire slips on rough roads for more than
10 seconds, the ABS brake warning lightmay come on. Turn OFF the ignition key,
restart the engine and drive the vehicle at
speeds above 20 MPH (30 km/h). If the
warning light does not go out, have the
vehicle checked at a NISSAN dealer.
Self-test featureThe anti-lock brake system consists of elec-
tronic sensors, electric pumps, and hydraulic
solenoids controlled by a computer. The com-
puter 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 pulsation 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 in the dashboard. The
brake system will then behave normally, but
without anti-lock assistance.
If the light comes on during the self check, or
while you are driving, you should take your
vehicle to your NISSAN dealer for repair at
your earliest convenience.

The 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 sys-
tem. Stopping distances may also be
longer on rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance from
the vehicle in front of you. Ultimately,
the responsibility for safety of self and
others rests in the hands of the driver.
Tire type and condition of tires may also
affect braking effectiveness.
IWhen replacing tires, install the
specified size of tires on all four
wheels.
IWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. SeeªTire placardº in the ª10. Technical
and consumer informationº section
for tire placard location information.
FREEING A FROZEN DOOR LOCKTo prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into the key hole.ANTI-FREEZEIn the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC), check
anti-freeze (ethylene glycol base) to assure
proper winter protection. For details, see ªEn-
gine Cooling Systemº in the ª8. Do-it-yourselfº
section.BATTERYIf the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
ªBatteryº in the ª8. Do-it-yourselfº section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-
ing the drain valves located under the radiator
and on the engine block. Refill before operat-
ing the vehicle. See ªEngine cooling systemº in

DRIVING ON SNOW OR ICEIWet ice (32ÉF, 0ÉC and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have a lot less traction or grip under
these conditions. Try to avoid driving
on wet ice until the road is salted or
sanded.
IWhatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels will
lose even more traction.
IAllow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
IAllow greater following distances on
slippery roads.
IWatch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake whileactually on the ice, and avoid any
sudden steering maneuvers.
IDo not use cruise control on slippery
roads.
ISnow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)An engine block heater to assist extreme cold
temperature starting is available through your
NISSAN dealer.Do not use your heater with an un-
grounded electrical system or two-
pronged (cheater) adapters. You can be
injured by an electrical shock if you use
an ungrounded connection.

CHANGING A FLAT TIREIf you have a flat tire, follow the instructions
below.Stopping the vehicle1. Safely move the vehicle off the road away
from traffic.
2. Turn on the hazard warning flasher.
3. Park on a level surface and apply the
parking brake. Shift the manual transmis-
sion into reverse (automatic transmission in
P).
The transfer control lever must
be in the 2H, 4H or 4L position.
Never place the transfer control lever in
the N position. Otherwise, the vehicle
could roll unexpectedly even if the
manual transmission is in gear or the
automatic transmission is in the P posi-
tion. This could result in serious per-
sonal injury or property damage.
4. Turn off the engine.5. Raise the hood to warn other traffic and to
signal professional road assistance person-
nel that you require assistance.
6. Have all passengers get out of the vehicle
and stand in a safe place away from traffic
and clear of the vehicle.
IMake sure that the parking brake is
securely applied and the manual
transmission is shifted into R (re-
verse), on the automatic transmis-
sion in P (Park).
INever change tires when the vehicle
is on a slope, ice or a slippery area.
This is hazardous.
INever change tires if oncoming traffic
is close to your vehicle. Wait for pro-
fessional road assistance.
Blocking wheelsPlace suitable blocks at both the front and
back of the wheel diagonally opposite the flat
tire.Be sure to block the wheel as the vehicle
may move and could cause personal
injury.

Jacking up the vehicle and removing
the damaged tireCarefully read the following instructions.
1. On models with 265/70 R15 size tires, put
the adapter stored in the tool bag on the
jack when jacking up the front side.
Do not use the jack adapter for the rear.
2. Place the jack directly under the jack-up
point.
The jack should be used on level firm
ground.3. Loosen each wheel nut one or two turns by
turning counterclockwise with the wheel nut
wrench.
Do not remove the wheel nuts until the tire
is off the ground.
4. Carefully raise the vehicle until the tire
clears the ground. To lift the vehicle, se-
curely hold the jack lever and rod with both
hands as shown above. Remove the wheel
nuts, and then remove the wheel. Do not
remove the brake drum with the wheel.
INever get under the vehicle while it is
supported only by the jack.
IUse only the jack provided with your
vehicle. Do not use the jack provided
with your vehicle on other vehicles.
The jack is designed only for lifting
your vehicle during a tire change.
IUse the correct jack up points; never
use any other part of the vehicle for
jack support.
INever jack up the vehicle more than
necessary.
INever use blocks on or under the
jack.
IDo not start or run engine while ve-
hicle is on the jack, as it may cause
the vehicle to move. This is especially
true for vehicle with limited slip dif-
ferential carriers.
IDo not allow passengers to stay in
the vehicle while it is on the jack

5. Securely store the spare tire and jacking
equipment in the vehicle.Always make sure that the spare tire and
jacking equipment are properly secured
after use. Such items can become dan-
gerous projectiles in an accident or sud-
den stop.
If you try to start your engine with a booster
battery, follow the instructions and precautions
below:IIf done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
IExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
it.
IDo not allow battery fluid to come
into contact with eyes, skin, cloth or
painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
IKeep battery out of the reach of chil-
dren.
IThe booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.IWhenever working on or near a bat-
tery, always wear suitable eye protec-
tors (for example, goggles or indus-
trial safety spectacles) and remove
rings, metal bands, or any other metal
jewelry. Do not lean over battery
when jump-starting.
IDo not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
IYour vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.JUMP STARTING

Always follow the instructions below
exactly. Failure to do so could result in
damage to the charging system and
cause personal injury.1. Position the two vehicles to bring their
batteries into close proximity to each other
if the booster battery is in another vehicle.
Do not allow the two vehicles to touch.
2. Apply parking brakes. Move the shift lever
to Neutral position (On automatic transmis-sion models, move the selector lever to P
(Park)). Switch off all unnecessary electri-
cal systems (light, heater, air conditioner,
etc.).
3. Remove vent caps on the battery (if so
equipped). Cover the battery with an old
cloth to reduce explosion hazard.
4. Connect jumper cables in the sequence as
illustrated.
IAlways connect positive (+) to posi-
tive (+) and negative (þ) to body
ground, (for example, engine lift
bracket, etc. Ð not to the battery).
IMake sure that cables do not touch
any moving parts in the engine com-
partment and that clamps do not con-
tact any other metal.5. Start the engine of the other vehicle and let
it run for a few minutes.
6. Keep the engine speed of the other vehicle
at about 2,000 rpm, and start your engine in
the normal manner.
Do not keep starter motor engaged for
more than 10 seconds. If the engine
does not start right away, turn the key
off and wait 3 to 4 seconds before trying
again.7. After starting your engine, carefully discon-
nect the negative cable and then the posi-
tive cable.
8. Replace the vent caps (if so equipped). Be
sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
