HEADED UPHILL WITH CURB:
2
Turn the wheels away from the curband
move the vehicle back until the curb side
wheel gently touches the curb.

HEADED UPHILL OR DOWNHILL, NO
CURB:
3
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 switch 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 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.
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.
BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brake
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 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 tapping 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 cause overheating of the brakes,
increases wear on the brake linings and pads,
and reduces gas mileage.

To 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.
WARNING

While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an acci-
dent.

If 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 control and helps to
minimize swerving and spinning on slippery sur-
faces.
Using the systemDepress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.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 ABS operationmay indicate that road conditions are hazardous
and extra care is required while driving.
Self-test featureThe anti-lock brake system consists of electronic
sensors, electric pumps, 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 pulsation in the brake pedal.
This is normal and is not an indication of any
malfunction. If the computer senses any mal-
function, it switches the anti-lock brake system
OFF and turns on the ABS warning light in the
meter. The brake system will then behave nor-
mally, 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 a NISSAN dealer for repair at your
earliest convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-

WARNING

Do not continue to drive if your ve-
hicle overheats. Doing so could
cause engine damage or a vehicle
fire.

To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the ra-
diator cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.

Do not open the hood if steam is
coming out.
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:
1. Move the vehicle safely off the road, apply the
parking brake and move the shift lever to the
P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi-tioner temperature control to maximum hot
and fan control to high speed.
3. If engine overheating is caused by climbing a
long hill on a hot day, run the engine at a fast
idle (approximately 1,500 rpm) until the tem-
perature gauge indication returns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or coolant
is escaping, turn off the engine.) Do not open
the hood further until no steam or coolant can
be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check if the cooling fan is running.
The radiator hoses and radiator should not
leak water.
If coolant is leaking or the cooling fan does
not run, stop the engine.
WARNING

Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or get caught in, drive
belt, or cooling fan.

The engine cooling fan can start at
any time when the coolant tempera-
ture is high.
7. 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 the
nearest NISSAN dealer.

CHANGING ENGINE COOLANTContact a NISSAN dealer if replacement is
required.

Major cooling system repairs should be per-
formed by a NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN Service Manual.

Improper servicing can result in reduced
heater performance and engine overheating.
WARNING

To avoid being scalded, never change
the coolant when the engine is hot.

Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.

Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.

Keep coolant out of reach of children
and pets.
CHECKING ENGINE OIL LEVEL1. Park the vehicle on a level surface and apply
parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick as illustrated and wipe it
clean. Reinsert it all the way.5. Remove the dipstick again and check the oil
level. It should be between the H and L marks
1. If the oil level is below the L mark
2,
remove the oil filler cap and pour recom-
mended oil through the opening.Do not
overfill
3.
6. Recheck oil level with dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the severity
of operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the
engine, and such damage is not covered
by warranty.

aftermarket fuel additives (for example, fuel in-
jector cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for gum,
varnish or deposit removal may contain active
solvent or similar ingredients that can be harmful
to the fuel system and engine.Octane rating tipsUsing unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer or other competent service fa-
cility.
However, now and then you may noticelight spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.9-4

CAUTION
Vehicle damage resulting from im-
proper towing procedures are not cov-
ered by NISSAN warranties. A NISSAN
Trailer Towing Guide (U.S. only) contain-
ing information on trailer towing ability
and the special equipment required may
be obtained from a NISSAN dealer.MAXIMUM LOAD LIMITS
Maximum trailer loadsNever allow the total trailer load to exceed the
value specified in the Towing Load/Specification
Chart found later in this section. The total trailer
load equals trailer weight plus its cargo weight.

When towing a trailer load of 1,000 lbs. (454
kg) or more, trailers with a brake system
MUST be used.
The maximum GCWR (Gross Combined Weight
Rating) should not exceed the value specified in
the following Towing Load/Specification Chart.
The GCWR equals the combined weight of the
towing vehicle (including passengers and cargo)
plus the total trailer load. Towing loads greaterthan these or using improper towing equipment
could adversely affect vehicle handling, braking
and performance.
The ability of your vehicle to tow a trailer is not
only related to the maximum trailer loads, but
also the places you plan to tow. Tow weights
appropriate for level highway driving may have to
be reduced on very steep grades or in low
traction situations (for example, on slippery boat
ramps).
Temperature conditions also can affect towing.
For example, towing a heavy trailer in high
outside temperatures on graded roads can af-
fect engine performance and cause overheating.
The transmission high fluid temperature protec-
tion mode, which helps reduce the chance of
transmission damage, could activate and auto-
matically decrease engine power. Vehicle speed
may decrease to 40 to 50 MPH (65 to 80 km/h)
under high load. Plan your trip carefully to ac-
count for trailer and vehicle load, weather, and
road conditions.
WARNING
Overheating can result in reduced en-
gine power and vehicle speed. Also,when the high temperature mode oper-
ates, vehicle speed may be gradually
reduced. The reduced speed may be
lower than other traffic, which could
increase the chance of a collision. Be
especially careful when driving. If nec-
essary, pull to the side of the road at a
safe place and allow the engine to cool
or the transmission to return to normal
operation.
Tongue loadKeep the tongue load between 9 to 11% of the
total trailer load within the maximum tongue load
limits shown in the following Towing
Load/Specifications Chart. If the tongue load
becomes excessive, rearrange cargo to allow for
proper tongue load.

load shift while driving.

Avoid abrupt starts, acceleration or stops.

Avoid sharp turns or lane changes.

Always drive your vehicle at a moderate
speed. Some states or provinces have spe-
cific speed limits for vehicles that are towing
trailers. Obey the local speed limits.

When backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and back
up slowly. If possible, have someone guide
you when you are backing up.

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
first block the wheels and apply the parking
brake, and then move the shift lever into the P
(Park) position. If you move the shift lever to
the P (Park) position before blocking the
wheels and applying the parking brake, trans-
mission damage could occur.

When going down a hill, shift into a lower
gear and use the engine braking effect.
When going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine overload-
ing and/or overheating.
If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan con-
trol to high and setting the temperature con-
trol to the HOT position.

If the transmission fluid rises to an extremely
high temperature, a high fluid temperature
protection mode may operate. See page
5-13 for details. If necessary, pull to the side
of the road at a safe place and let the
transmission cool before continuing.

Trailer towing requires more fuel than normal
circumstances.

Avoid towing a trailer for the first 500 miles
(800 km).

Have your vehicle serviced more often than at
intervals specified in the recommended main-
tenance schedule.

When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this, make
a larger than normal turning radius during the
turn.

Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed bylarger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce ve-
hicle speed. This combination will help stabi-
lize the vehicle. Never increase speed.

Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal passing.
Remember the length of the trailer must also
pass the other vehicle before you can safely
change lanes.

Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking ef-
ficiency.

Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.

Do not use cruise control while towing a
trailer.

Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.

When stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position.
