WARNING
cAlways have the doors locked while
driving. Along with the use of seat belts,
this provides greater safety in the event
of an accident by helping to prevent
persons from being thrown from the
vehicle. This also helps keep children
and others from unintentionally open-
ing the doors, and will help keep out
intruders.
cBefore opening any door, always look
for and avoid oncoming traffic.
cDo not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended
children could become involved in seri-
ous accidents.
LOCKING WITH KEY
The power door lock system allows you to lock or
unlock all doors at the same time.
Turning the key toward the front
s1of the vehicle
locks all doors.
Turning the key one time toward the rear
s2of the
vehicle unlocks that door. From that position,
returning the key to neutral
s3(where the key can
only be removed and inserted) and turning it
toward the rear again within 5 seconds unlocks
all doors
s4.
Opening and closing windows
The driver’s door key operation allows you to
open and close the front door windows at the
same time.
cTo open the windows, turn the driver’s door
key toward the rear of the vehicle forlonger
than 1 secondafter the door is unlocked.

TELESCOPIC OPERATION
Push the lever down and adjust the steering
wheel forward or backward to the desired posi-
tion.
Pull the lock lever up firmly to lock the steering
wheel in place.
WARNING
Do not adjust the steering wheel any
closer to you than is necessary for proper
steering operation and comfort. The driv-
er’s air bag inflates with great force. If you
are unrestrained, leaning forward, sitting
sideways or out of position in any way, you
are at greater risk of injury or death in a
crash. You may also receive serious or
fatal injuries from the air bag if you are up
against it when it inflates. Always sit back
against the seatback and as far away as
practical from the steering wheel. Always
use the seat belts.Slide the sun visor extension in or out as needed
(if so equipped) .
CAUTION
Do not store the sun visor before returning
it to its original position.
VANITY MIRRORS (if so equipped)
To access the vanity mirror, pull the sun visor
down and flip open the mirror cover. Some vanity
mirrors are illuminated and turn on when the
mirror cover is open.

CAUTION
cDo not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
cKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
cAvoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
cDo not race the engine while warming it
up.
cDo not push or tow your vehicle to start
the engine.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss of
control or an accident.
Be alert and drive defensively at all times. Obey
all traffic regulations. Avoid excessive speed,
high speed cornering, or sudden steering ma-
neuvers, because these driving practices could
cause you to lose control of your vehicle.As with
any vehicle, loss of control could result in a
collision with other vehicles or objects, or
cause the vehicle to roll over, particularly if
the loss of control causes the vehicle to
slide sideways.Be attentive at all times, and
avoid driving when tired. Never drive when under
the influence of alcohol or drugs (including pre-
scription or over-the-counter drugs which may
cause drowsiness) . Always wear your seat belt
as outlined in the “Safety – Seats, seat belts and
supplemental air bags” section of this manual,
and also instruct your passengers to do so.
Seat belts help reduce the risk of injury in colli-
sions and rollovers.In a rollover crash, an
unbelted person is significantly more likely
to die than a person wearing a seat belt.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood
of being involved in an accident injuring
yourself and others. Additionally, if you
are injured in an accident, alcohol can
increase the severity of the injury.
NISSAN is committed to safe driving. However,
you must choose not to drive under the influence
of alcohol. Every year thousands of people are
injured or killed in alcohol-related accidents. Al-
though the local laws vary on what is considered
to be legally intoxicated, the fact is that alcohol
affects all people differently and most people
underestimate the effects of alcohol.
Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter, pre-
scription, and illegal drugs) . Don’t drive if your
ability to operate your vehicle is impaired by alco-
hol, drugs, or some other physical condition.

minders” in the “Instruments and controls”
section of this manual.1. Apply the parking brake.
2.Automatic transmission:
Move the shift selector lever to P (Park) or N
(Neutral) . P (Park) is recommended.
The shift selector lever cannot be
moved out of P (Park) and into any of
the other gear positions if the ignition
key is turned to the OFF position or if
the key is removed from the ignition
switch.
The starter is designed not to operate if
the shift selector lever is in any of the
driving positions.
Manual transmission:
Move the shift lever to N (Neutral) . Depress
the clutch pedal to the floor while cranking
the engine.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
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.cWhen the engine is very hard to start in
extremely cold weather or when restart-
ing, depress the accelerator pedal a little
(approximately 1/5 to the floor) and hold it
and then crank the engine. Release the
key and the accelerator pedal when the
engine starts.
cWhen the engine is very hard to start
because it is flooded, depress the accel-
erator pedal all the way to the floor and
hold it. Crank the engine for 5-6 seconds.
After cranking the engine, release the ac-
celerator pedal. 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.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, turn the key off and wait 10
seconds before cranking again, otherwise
the starter could be damaged.

cHEADED UPHILL OR DOWNHILL, NO
CURB:
sC
Turn the wheels toward the side of the road
so the vehicle will move away from the cen-
ter 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.

If your vehicle is overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect abnormal
noise, etc. take the following steps.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause a ve-
hicle 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 com-
ing out.
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever to
N (Neutral) (manual transmission) or to P
(Park) (automatic transmission) .
Do not stop the engine.
2. Turn off the air conditioner (if so equipped) .
Open all the windows, move the heater or air
conditioner temperature control to maximum
hot and fan control to high speed.3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Wait
until no steam or coolant can be seen before
proceeding.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling
fan can start at any time when the coolant
temperature is high.6. After the engine cools down, check the cool-
ant level in the reservoir tank with the engine
running. Add coolant to the reservoir tank if
necessary. Have your vehicle repaired at a
NISSAN dealer.

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 completely in the shade
before using them. See “Seat belt maintenance”
in the “Safety – Seats, seat belts and supplemen-
tal air bags” section of this manual.
WARNING
Do not allow wet seat belts to roll up in the
retractor. NEVER use bleach, dye or
chemical solvents to clean the seat belts,
since these materials may severely
weaken the seat belt webbing.
MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
1. The accumulation of moisture-retaining dirt
and debris in body panel sections, cavities,
and other areas.
2. Damage to paint and other protective coat-
ings caused by gravel and stone chips or
minor traffic accidents.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on the ve-
hicle body underside can accelerate corrosion.
Wet floor coverings will not dry completely inside
the vehicle, and should be removed for drying to
avoid floor panel corrosion.
Relative humidity
Corrosion will be accelerated:
cin areas of high relative humidity.
cin areas where the temperatures stay above
freezing.
cwhere atmospheric pollution exists.cwhere road salt is used.
Temperature
High temperatures accelerate the rate of corro-
sion 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 acceler-
ates the corrosion process. Road salt also accel-
erates the disintegration of paint surfaces.
TO PROTECT YOUR VEHICLE
FROM CORROSION
cWash and wax your vehicle often to keep the
vehicle clean.
cAlways check for minor damage to the paint
and repair it as soon as possible.
cKeep drain holes at the bottom of the doors
open to avoid water accumulation.
cCheck the underbody for accumulation of
sand, dirt or salt. If present, wash with water
as soon as possible.
