AUDIBLE REMINDERS
Key reminder chime
A chime sounds if the driver's side door is
opened while the key is left in the ignition
switch. Remove the key and take it with you
when leaving the vehicle.
Light reminder chime
With the ignition switch in the OFF position,
a chime sounds when the driver's side door
is opened if the headlights or parking lights
are on.
Turn the headlight control switch off before
leaving the vehicle.
Brake pad wear warning
The disc brake pads have an audible wear
warning. When a brake pad requires re-
placement, it makes a high pitched scraping
sound when the vehicle is in motion,
whether or not the brake pedal is de-
pressed. Have the brakes checked as soon
as possible if the warning sound is heard.Your vehicle has two types of security sys-
tems:
cNissan Vehicle Immobilizer System±
NVIS (if so equipped)
cVehicle security system (if so equipped)
NISSAN VEHICLE IMMOBILIZER
SYSTEM (NVIS) (if so equipped)
The Nissan Vehicle Immobilizer System
(NVIS) will not allow the engine to start
without the use of a registered NVIS key.
If the engine fails to start using a registered
NVIS key (for example, when interference iscaused by another NVIS key, an automated
toll road device or automated payment de-
vice on the key ring), restart the engine
using the following procedures:
1. Leave the ignition switch in the ON posi-
tion for approximately 5 seconds.
2. Turn the ignition switch to the OFF or
LOCK position, and wait approximately 5
seconds.
3. Repeat step 1 and 2.
4. Restart the engine while holding the de-
vice (which may have caused the inter-
ference) separate from the registered
NVIS key.
If the no start condition re-occurs, Nissan
recommends placing the registered NVIS
key on a separate key ring to avoid interfer-
ence from other devices.

The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
BRAKING 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 distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This overheats 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
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.
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 the brakes, drive the vehicle at a safe
speed while lightly pressing 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.
ANTI-LOCK BRAKE SYSTEM
(ABS) (if so equipped)
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
BRAKE SYSTEM
Starting and driving5-19
ZX

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 a sophisti-
cated device with electronic sensors, elec-
tric pumps, and hydraulic solenoids con-
trolled by a computer. The computer has a
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 op-erates normally, but without anti-lock assis-
tance.
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 remember that the stop-
ping distance on slippery surfaces
will be longer than on normal sur-
faces, even with the anti-lock brake
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 of tires may
also affect braking effectiveness.cWhen replacing tires, install the
specified tire size 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 ``Technical and
consumer information'' section of
this manual.
cFor additional information, refer to
``Wheels and tires'' in the ``Mainte-
nance and do-it-yourself'' section of

CHECKING BRAKE PEDAL
With the engine running, check the distance
between the upper surface of the pedal and
the metal floor. If it is out of the range shown
above, see an authorized NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front (and rear, if equipped) disc-type
brakes self-adjust every time the brake
pedal is applied. The rear drum-type brakes
also self-adjust every time the brake pedal
is applied.If the brake pedal goes down farther than
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 for a
brake system check if the brake pedal
height does not return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have
an audible wear indicator. 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. Shouldyou ever hear an unusually loud noise from
the rear drum brakes, have them inspected
as soon as possible by an authorized
NISSAN dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``NISSAN Service and Maintenance Guide''.
BRAKE BOOSTER
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.
CHECKING CLUTCH PEDAL
Press the pedal by hand and be sure the
free travel is within the limits shown above.
If free travel is out of the range shown
above, see an authorized NISSAN dealer.
CAUTION
Never use a fuse of higher amperage
rating than specified on the fuse box
cover. This could damage the electrical
system or cause a fire.
ENGINE COMPARTMENT
If any electrical equipment does not come
on, check for an open fuse.
1. Be sure the ignition switch and the head-
light switch are OFF.
2. Open the engine hood.

cDo not modify the vehicle exhaust
system, brake system, etc. to install
a trailer hitch.
cTo reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.
cAfter the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.
cRegularly check that all hitch mount-
ing bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (lo-
cated on the driver's side rear door
pillar).
cTrailer tire condition, size, load rating
and proper inflation pressure should be
in accordance with the trailer and tire
manufacturers' specifications.
Safety chains
Always use suitable safety chains between
your vehicle and the trailer. Safety chains
should be crossed and should be attached
to the hitch, not to the vehicle bumper or
axle. Be sure to leave enough slack in the
chains to permit turning corners.
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 unloadedtrailer 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.

cAlways 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 (Park)
position. If you move the shift selector
lever to the P (Park) position before block-
ing the wheels and applying 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 in the
ªNISSAN Service and Maintenance
Guideº.
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.
cCrosswinds and rough roads adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and imme-
diately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of thetrailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
cAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change the oil in
the transmission more frequently. For
additional information see the ``Mainte-
nance and do-it-yourself'' section earlier
in this manual.
