1. Apply the parking brake.
2.Automatic transmission:
Move the selector lever to P (Park) or N
(Neutral). (P preferred.)
The shift lever cannot be moved out of
P and into any of the other gear posi-
tions if the ignition key is turned to
OFF or if the key is removed from the
switch.
The starter is designed not to operate
if the shift lever is in one of the driving
positions.
Manual transmission:
Move the gearshift lever to N (Neutral),
and depress the clutch pedal to the floor
while cranking the engine.
The starter is designed not to operate
unless the clutch pedal is depressed.
3. Crank the enginewith your foot off the
accelerator pedalby turning the ignition
key to START. Release the key when the
engine starts. If the engine starts, but
fails to run, repeat the above procedure.
Ð If the engine is very hard to start in
extremely cold or hot weather, de-
press the accelerator pedal fully andhold it to help start the engine.
Ð In the summer, when restarting the
engine within 30 minutes after it has
been stopped, keep the accelerator
pedal fully depressed while starting.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, wait 10 seconds before crank-
ing again, otherwise the starter could
be damaged.
4.Warm-up
Allow the engine to idle for at least 30
seconds after starting. Drive at moderate
speed for a short distance first, especially
in cold weather.To engage:pull the lever up.
To release:pull the lever up slightly, push
the button and lower completely. Before
driving, be sure the parking brake warning
light goes out.

cAccelerate slowly and smoothly. Main-
tain cruising speeds with a constant ac-
celerator position.
cDrive at moderate speeds on the high-
way. Driving at high speed lowers fuel
economy.
cAvoid unnecessary stopping and brak-
ing. 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 main-
tenance schedule.
cKeep the tires inflated at the correct
pressure. Low pressure increases tire
wear and waste fuel.
cKeep the front wheels in correct align-
ment. Improper alignment causes not
only tire wear but also lower 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 condi-
tioner and leave the windows closed to
reduce drag.

cDriving with 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 pres-
sure on the brake pedal will be required
to stop the vehicle and the stopping
distance will be longer.
cDriving with the power assisted steer-
ing:
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
or at low speeds.
cWet 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 brakepedal 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.
cAvoid 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.
cTo help save the brakes 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.
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking actions or
sudden acceleration could cause the
wheels to skid.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 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 prevent-
ing wheel lockup, the system helps the
driver maintain steering control and helps to
minimize swerving and spinning on slippery
surfaces.
Using the system
Depress the brake pedal and hold it down.
It is not necessary to pump the brake
pedal.
Doing so may result in increased stopping
distances.
Normal operation
The anti-lock brake system does not oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h) to completely stop the vehicle. (The
speeds 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 pump-
ing the brakes very quickly). While the ac-

tuator is working, you may feel a pulsation in
the brake pedal and hear a noise or vibra-
tion 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.
Self-test feature
The anti-lock brake system consists of elec-
tronic sensors, electric pumps, and hydrau-
lic 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 ``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 then operates normally, but without
anti-lock assistance.
If the light comes on during the self check,
or while driving, take your vehicle to your
NISSAN dealer for repair at your earliest
convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent
accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces, but re-
member that the stopping distance on
slippery surfaces will be longer than on
normal surfaces, even with the anti-
lock system. Stopping distances may
also be longer on rough, gravel or
snow covered roads, or if you are using
tire chains. Always maintain a safe dis-
tance 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 may also affect
braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all 4 wheels.
c
When 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
placard'' in the Owner's Manual index.Refer to ``Wheels and tires'' in the ``Do-
it-yourself operations'' section of this
manual.

Freeing a frozen door lock
To 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-freeze
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check the anti-freeze (ethylene glycol base)
to assure proper winter protection. For de-
tails, see ``Engine cooling system'' in the
``Do-it-yourself operations'' section.
Battery
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Do-it-yourself
operations'' section.
Draining of coolant water
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the
radiator and on the engine block. Refillbefore operating the vehicle. See ``Chang-
ing Engine Coolant'' in the ``Do-it-yourself
operations'' section.
Tire equipment
1. The SUMMER tires are of a tread design
to provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all
four wheels. Please consult your NIS-
SAN dealer for the tire type, size, speed
rating and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
provinces and states prohibit their use.
Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
3. Snow chains may be used if desired.
Make sure they are of proper size for the
tires on your vehicle and are installedaccording to the chain manufacturer's
suggestions.
Use of tire chains may be prohibited
according to location. Check the local
laws before installing tire chains. When
installing tire chains, make sure they are
of proper size for the tires on your vehicle
and are installed according to the chain
manufacturer's suggestions.Use only
SAE Class ªSº chains.Use chain ten-
sioners when recommended by the tire
chain manufacturer to ensure a tight fit.
Loose end links of the tire chain must be
secured or removed to prevent the pos-
sibility of whipping action damage to the
fenders or underbody. If possible, avoid
fully loading your vehicle when using tire
chains. In addition, drive at a reduced
speed, otherwise, your vehicle may be
damaged and/or vehicle handling and
performance may be adversely affected.
Never install tire chains on T-type and
small size spare tires. Do not use the
chains on dry roads.

Cleaning interior
Occasionally remove loose dust from the
interior trim and seats using a vacuum
cleaner or soft brush. Wipe the vinyl and
leather surfaces with a clean, soft cloth
dampened in mild soap solution, then wipe
clean with a dry soft cloth. Before using any
fabric protector, read the manufacturer's
recommendations. Some fabric protectors
contain chemicals that may stain or bleach
the seat material.
CAUTION
cNever use benzine, thinner, or any
similar material.
cThe leather seats should be regularly
coated with a leather wax like saddle
soap. Never use car wax.
cNever use fabric protectors unless
recommended by the manufacturer.
Floor mat positioning aid
(Driver side only)
All models include a front floor mat bracket
to act as a floor mat positioning aid. NIS-
SAN floor mats have been specially de-
signed for your vehicle model. The driver's
side floor mat has a grommet hole incorpo-
rated in it. Simply position the mat by plac-
ing the floor mat bracket hook through the
floor mat grommet hole while centering the
mat in the floor pan contour.
Periodically check to make certain the mats
are properly positioned.
Floor mats
The use of genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. No
matter what mats are used, be sure they are
fitted for your vehicle and are properly posi-
tioned in the footwell to prevent interference
with pedal operation. Mats should be main-
tained with regular cleaning and replaced if
they become excessively worn.
Seat belts
The seat belts can be cleaned by wiping
them with a sponge dampened in a mild
soap solution. Allow the belts to dry com-
pletely before using them. Do not allow wet
belts to roll up in the retractor. NEVER use
bleach, dye, or chemical solvents since
these may severely weaken the seat belt

When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the gearshift
control lever to Neutral (N).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
cDo not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
cBe sure to turn the ignition key to the
OFF or LOCK position.
When the ignition key is in the ON or
ACC position, the cooling fan may
start to operate suddenly even when
the engine is not running.
cIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.cIt is advisable to remove ties and any
jewelry, such as rings, watches, etc.,
before working on your vehicle.
cIf you must run the engine in an en-
closed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
cNever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle, sup-
port it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel and battery.
cNever connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition is
on.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) system,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
cFailure to follow these or other com-
mon sense guidelines may lead to
serious injury or vehicle damage.cImproperly disposed motor oil and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid. Avoid contact with used motor
oil.
This ``Do-it-yourself operations'' section
gives instructions regarding only those
items which are relatively easy for an owner
to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by your NISSAN dealer.
