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
cWhile 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.
cIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
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 preventing wheel
lockup, the system helps the driver maintain
steering control and helps to minimize swerv-
ing and spinning on slippery surfaces.
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.
Normal operation
The anti-lock brake system does not oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h). 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 pres-
sure (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.
Self-test feature
The anti-lock brake system is sophisticated,
with electronic sensors, electric pumps, and
hydraulic solenoids controlled by a com-
puter. The computer has a built-in diagnos-
tic 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 indica-
tion 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-test or
while driving, take the vehicle to an autho-
rized NISSAN dealer for repair.

WARNING
c
The anti-lock brake system is a so-
phisticated device, but it cannot pre-
vent accidents resulting from care-
less or dangerous driving tech-
niques. It can help maintain vehicle
control during braking on slippery
surfaces, but the stopping distance
on slippery surfaces will be longer
than on normal surfaces, even with
the anti-lock system. 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 ve-
hicle in front of you. Ultimately, the
responsibility for safety of self and
others rests in the hands of the driver.
cTire type and condition may also
affect braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all four
wheels.c
When installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
``Tire placard'' in the Owner's Manual
index.
cRefer to ``Wheels and tires'' in the
``Do-it-yourself'' section of this
manual.
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 the anti-freeze (ethylene glycol base)
to assure proper winter protection. For de-
tails, 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
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
COLD WEATHER DRIVING

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.
cWatch 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 while
actually on the ice, and to avoid any
sudden steering maneuvers.
cDo not use cruise control on slippery
roads.
cSnow 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 an authorized NISSAN dealer.
WARNING
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.

CAUTION
cAutomatic transmission models can-
not be push started. This may cause
transmission damage.
cThree-way catalytic converter
equipped models should not be
started by pushing since the three
way catalyst may be damaged.
cNever try to start the vehicle by tow-
ing it; when the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle.If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power,
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
shift lever to N (Neutral) (manual trans-
mission) or the shift selector lever to P
(Park) (automatic transmission).
Do not stop the engine.
2. Turn off the air conditioner. Open all the
windows, move the heater or air condi-
tioner temperature control to maximumhot 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 rpm)
until the temperature gauge indication
returns 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, the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.

9. Stop the engine. After it completely
cools down, refill the radiator up to the
filler opening. Fill the reservoir tank up
to the MAX level.
10. Open and close the air release plug(s)
to release air. Then fill the radiator again
and install the radiator cap.
11. Check the drain plugs on the radiator
and the engine block for any sign of
leakage. Also check the air release plug
for any sign of leakage.CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Start the engine and let it idle until it
reaches operating temperature.3. Turn off the engine.Wait a few minutes
for the oil to drain back into the oil
pan.
4. Remove the dipstick 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
(High) and L (Low) marks. If the oil level
is below the L (Low) mark, remove the oil
filler cap and pour recommended oil
through the opening.Do not overfill.

normal, it may be due to a lack of adjust-
ment of the rear drum brakes. To adjust
apply the parking brake several times.
WARNING
See an authorized NISSAN dealer and
have it checked if the brake pedal
height does not return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it makes a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear
indicator sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
The rear drum brakes (if so equipped) do
not have audible wear indicators. Should
you ever hear an unusually loud noise fromthe rear drum brakes, have them inspected
as soon as possible by an authorized NIS-
SAN dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance'' section of this manual.Check the brake booster function as fol-
lows:
1. With the engine off, press and release
the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one pedal
application to the next, continue on to the
next step.
2. While depressing the brake pedal, start
the engine. The pedal height should drop
a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height
should not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it
off. Depress the brake pedal several
times. The pedal travel distance will de-
crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, see an
authorized NISSAN dealer.

Trailer lights
Trailer lights should comply with federal
and/ or local regulations. When wiring the
vehicle for towing, connect the stop and tail
light pickup into the vehicle electrical circuit.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is prop-
erly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if
it has an abnormal nose-up or nose- down
condition; check for improper tongue load,
overload, worn suspension or other pos-
sible causes of either condition.
cAlways secure items in the trailer to
prevent load shift while driving.cBe certain your rear view mirrors con-
form to all federal, state or local regula-
tions. If not, install any mirrors required
for towing before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability, and braking performance are
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
c
Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with an automatic transmission,
first block the wheels and apply the park-
ing brake, and then move the transmis-
sion shift selector lever into the P position.
If you move the shift selector lever to the P
position before blocking the wheels andapplying the parking brake, transmission
damage could occur.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
cIf the engine temperature 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 win-
dows, switching the fan control to high
and setting the temperature control to
the HOT position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for your vehicle's
first 500 miles (800 km).
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.

Due to legal requirements in some states
and Canadian provinces, your vehicle may
be required to be in the ready condition for
an Inspection/Maintenance (I/M) test of the
emission control system.
The vehicle is set to the ready condition
when it is driven through certain driving pat-
terns. Usually, the ready condition can be
obtained by ordinary usage of the vehicle.
If a powertrain system component is repaired
or the battery is disconnected, the vehicle
may be reset to a not ready condition. Before
taking the I/M test, drive the vehicle through
the following pattern to set the vehicle to the
ready condition. If you cannot or do not want
to perform the driving pattern, a NISSAN
dealer can conduct it for you.
WARNING
Always drive the vehicle in a safe man-
ner according to traffic conditions and
obey all traffic laws.
1. Start the engine when the engine coolant
temperature gauge needle points to C.
Allow the engine to idle until the gauge
needle points between the C and H (nor-
mal operating temperature).2. Accelerate the vehicle to 55 mph (88
km/h), then quickly release the accelera-
tor pedal completely and keep it released
for at least 6 seconds.
3. Quickly depress the accelerator pedal for
a moment, then drive the vehicle at a
speed of 53 to 60 mph (86 to 96 km/h) for
at least 5 minutes.
4. Stop the vehicle.
5. Accelerate the vehicle to 35 mph (55
km/h) and maintain the speed for 20
seconds.
6. Repeat steps four through five at least
three times.
7. Accelerate the vehicle to 55 mph (88
km/h) and maintain the speed for at least
3 minutes.
8. Stop the vehicle and turn the engine off.
9. Repeat steps one through eight at least
one more time.
If step one through seven is interrupted,
repeat the preceding step. Any safe driving
mode is acceptable between steps. Do not
stop the engine until step seven is com-
pleted.
