Open the glove box by pulling the handle.
CAUTION
Keep glove box lid closed while driving
to prevent injury in an accident or a
sudden stop.The fuel filler cap is a screw-on ratcheting
type. Tighten the cap clockwise until ratch-
eting clicks are heard.
WARNING
cGasoline is extremely flammable and
highly explosive under certain con-
ditions. You could be burned or se-
riously injured if it is misused or
mishandled. Always stop the engine
and do not smoke or allow open
flames or sparks near the vehicle
when refueling.cFuel may be under pressure. Turn
the cap one-half turn and wait for
any ``hissing'' sound to stop to pre-
vent fuel from spraying out and
causing possible personal injury.
Then remove the cap.
cDo not attempt to top off the fuel
tank after the fuel pump nozzle shuts
off automatically. Continued refuel-
ing may cause fuel overflow, result-
ing in fuel spray and possibly fire.
cUse only a genuine NISSAN fuel filler
cap as a replacement. It has a built-in
safety valve needed for proper op-
eration of the fuel system and emis-
sion control system. An incorrect
cap can result in a serious malfunc-
tion and possible injury.
cNever pour fuel into the throttle body
to attempt to start your vehicle.
CAUTION
cIf fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage.

cMake sure the area around the vehicle is
clear.
cCheck fluid levels such as engine oil,
coolant, brake and clutch fluid, and win-
dow washer fluid as frequently as pos-
sible, at least whenever you refuel.
cCheck that all windows and lights are
clean.
cVisually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
cLock all doors.
cPosition seat and adjust head restraints.
cAdjust inside and outside mirrors.
cFasten seat belts and ask all passengers
to do likewise.
c
Check the operation of warning lights when
key is turned to the ON (3) position. See
``Warning/indicator lights and chimes'' in
the ``Instruments and controls'' section.
WARNING
cDo not depress the accelerator pedal
while shifting from P (Park) or N
(Neutral) to R (Reverse), D (Drive), 2
or 1. Always depress the brake pedal
until shifting is completed. Failure to
do so could cause you to lose con-
trol and have an accident.
cCold engine idle speed is high, so
use caution when shifting into a for-
ward or reverse gear before the en-
gine has warmed up.
cNever shift to P (Park) or R (Reverse)
while the vehicle is moving. This
could cause an accident.
CAUTION
cWhen stopping the vehicle on an
uphill grade, do not hold the vehicle
by depressing the accelerator pedal.
The foot brake should be used for
this purpose.
cOn slippery roads, do not downshift.
This may cause a loss of control.
The automatic transmission in your vehicle
is electronically controlled by a transmission
control module to produce maximum power
and smooth operation.
The recommended operating procedures for
this transmission are shown on the following
pages. Follow these procedures for maximum
vehicle performance and driving enjoyment.
Starting the vehicle
cAfter starting the engine, fully depress
the foot brake pedal to ensure the vehicle
is at a complete stop before attempting to
shift the selector lever.
cKeep the foot brake pedal depressed and
shift the selector lever into a driving gear.
cRelease the foot brake, then gradually
start the vehicle in motion.
This automatic transmission is designed
so the foot brake pedal MUST be de-
pressed before shifting from P (Park) to
any drive position while the ignition
switch is ON.
The shift lever cannot be moved out of P
(Park) and into any of the other gear
positions if the ignition key is turned to
LOCK or if the key is removed.
If the battery charge is low, the shift lever
can be moved if the ignition switch is in
the ACC position.

Precautions
cThe cruise indicator light in the instru-
ment panel may blink when the cruise
control main switch is turned ON while
pushing the RES/ACCEL, COAST/SET,
or CANCEL switch. To properly set the
cruise control system, perform the pre-
ceding steps in the order indicated.
cIf the cruise control system malfunctions,
it cancels automatically. The CRUISE
light in the instrument panel then blinks to
warn the driver.
cIf the cruise light blinks, turn the cruisecontrol main switch off and have the
system checked by an authorized NIS-
SAN dealer.
WARNING
Don't use the cruise control when driv-
ing under the following conditions:
cit is not possible to keep the vehicle
at a set speed.
cin heavy traffic or in traffic that var-
ies 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 neutral without depress-
ing the clutch pedal when the cruise
control is on. Should this occur, de-
press the clutch pedal and turn the
main switch off immediately. Failure to
do so may cause engine damage.
The cruise control allows driving at a fixed
speed between 30 and 90 MPH (48 and 145
km/h) without keeping your foot on the
accelerator pedal.
To turn on the cruise control,push the
main switch on. The CRUISE CONT indica-
tor light comes on.

built-in diagnostic feature that tests the sys-
tem 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 an abnormality occurs in the system, the
anti-lock function will cease but the ordinary
brakes will continue to operate normally. The
ABS brake warning light will then come on.
If the light comes on while you are driving,
contact an authorized NISSAN dealer for
repair.
Using the System
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
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 under
some conditions, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances 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 may also affect
braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all four
wheels.
cWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. See
``Tire placard'' in the ``Technical and
consumer information'' section.Freeing a frozen door lock
To prevent a door lock from freezing, apply
de-icer or glycerin through the key hole. If
the lock becomes frozen, heat the key be-
fore inserting it in the key hole.
Anti-freeze
In 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 ``Engine cooling system'' in the ``Do-it-
yourself'' section of this manual.
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''
section of this manual.
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. Refill

before operating the vehicle. For details,
see ``Changing engine coolant'' in the ``Do-
it-yourself'' section of this manual.
Tire equipment
1. SUMMER tires have a tread designed 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 on all four
wheels of MUD & SNOW or ALL SEA-
SON tires. Please consult your NISSAN
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
U.S. states and Canadian provinces pro-
hibit 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. Tire chains may be used. Use of tire
chains may be prohibited according tolocation. 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 manufac-
turer's suggestions.Use only SAE
Class ``S'' chains.Other types may
damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose
end links of the tire chain must be se-
cured or removed to prevent the possi-
bility of whipping action damage to the
fenders or undercarriage. 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 af-
fected. Never install tire chains on a
TEMPORARY USE ONLY spare tire. Do
not use tire chains on dry roads.
Special winter equipment
It is recommended that the following items
be carried in the vehicle during winter:
1. A scraper and stiff-bristled brush to re-
move ice and snow from the windows
and wiper blades.2. A sturdy, flat board to be placed under
the jack to give it firm support.
3. A shovel to dig the vehicle out of snow-
drifts.
4. Extra window washer fluid to refill the
reservoir tank.
Driving on snow or ice
WARNING
cWet ice (32ÉF, 0ÉC and freezing rain),
very cold snow, or ice can be slick
and very hard to drive on. The ve-
hicle 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.
cWhatever 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.
c
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
cAllow greater following distances on
slippery roads.

If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power, or
detect abnormal noise, etc., take the follow-
ing steps:
WARNING
cDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
cTo avoid the danger of being
scalded, never remove the radiator
cap while the engine is still hot.
When the radiator cap is removed,
pressurized hot water will spurt out,
possibly causing serious injury.
cDo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road,
apply the parking brake and move the
gearshift lever to N (Neutral), or the au-
tomatic transmission into P (Park).
Do not stop the engine.
2.
Turn off the air conditioner (if so
equipped). Open all of the windows,
move the heater or air conditioner tem-perature control to maximum hot and fan
control to high speed.
3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 r/min)
until the temperature gauge indicator re-
turns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait until
no steam or coolant can be seen before
proceeding.
5. Open the hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or
looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water. If coolant is
leaking, or the water pump belt is missing
or loose, or the cooling fan does not run,
stop the engine.
WARNING
cBe careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or to get caught in, the
running fan or belts.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the res-
ervoir tank if necessary. Have your ve-
hicle repaired at an authorized NISSAN
dealer.
