c) Push, then quickly release the ªACCELº set
switch. Each time you do this, the set speed
will increase by about 1 MPH (1.6 km/h).
To reset at a slower cruising speed,follow
either of these three methods:
a) Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
ªCOAST/SETº switch and release it.
b) Push and hold the ªCOAST/SETº switch.
Release the switch when the vehicle slows
down to the desired speed.
c) Push, then quickly release the
ªCOAST/SETº switch. Each time you do
this, the set speed will decrease by about 1
MPH (1.6 km/h).
To resume the preset speed,push and re-
lease the ªRESUMEº set switch. The vehicle
will resume the last set cruising speed when
the vehicle speed is over 30 MPH (48 km/h).
Precautions
IThe cruise indicator may sometimes blink
when the cruise control switch (Main
switch) is turned ªONº while pushing the
ªRESUME/ACCELº switch or
ªCOAST/SETº switch or ªCANCELº switch
(located on the steering wheel). To properly
set the cruise control system perform thesteps above in the order indicated. (This is
a fail-safe mode. Turn the main switch
ªOFFº and turn it ªONº again without push-
ing the set switch to return to normal opera-
tion.)
IIf the cruise control system malfunctions, it
will cancel automatically. The cruise indica-
tor in the meter assembly will then blink to
warn the driver.
IWhen the cruise indicator blinks, turn the
cruise control switch (Main switch) ªOFFº
and have the system checked by your
NISSAN dealer.
Avoid using the cruise control when driv-
ing under the following conditions:
Iwhen it is not possible to keep the vehicle at
set speed.
Iin heavy traffic or in traffic that varies in
speed.
Ion winding or hilly roads.
Ion slippery roads (rain, snow, ice, etc.)
Iin very windy areas.
On the manual transmission model, do
not shift into neutral position without
depressing the clutch pedal when the
cruise control is on. This could cause
engine damage. If you shift into neutral
without depressing the pedal, depress
the clutch pedal and turn the main
switch off immediately.

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 con-
trol and helps to minimize swerving and spin-
ning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.It is
not necessary to pump the brake pedal.
Doing so may result in increased stopping
distances.
Normal operation
The 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 pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.
If a tire slips on rough roads for more than
10 seconds, the ABS brake warning light
may come on. Turn OFF the ignition key,
restart the engine and drive the vehicle at
speeds above 20 MPH (30 km/h). If the
warning light does not go out, have the
vehicle checked at a NISSAN dealer.
Self-test feature
The anti-lock brake system consists of elec-
tronic sensors, electric pumps, and hydraulic
solenoids controlled by a computer. The com-
puter 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 ªself-testº occurs, you may
hear a ªclunkº noise and/or feel a ªpulsationº 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 ªABSº
brake warning light in the dashboard. The
brake system will then behave normally, 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 your NISSAN dealer for repair atyour earliest convenience.
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces, even with the anti-lock sys-
tem. Stopping distances 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.
IWhen replacing tires, install the
specified size of tires on all 4 wheels.
Refer to ªWheels and tiresº in the
ªDo-it-yourself operationsº section.
IWhen 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
ªTire placardº in the Owner's Manual
index.Freeing a frozen door lock
To prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into 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 ªEn-
gine Cooling Systemº in the ªDo-it-yourself
operationsº section.
Battery
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
ªBatteryº in the ªDo-it-yourself operationsº sec-
tion.
Draining of coolant water
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-
ing the drain valves located under the radiator
and on the engine block. Refill before operat-
ing the vehicle. For details, see ªChangingEngine Coolantº in the ªDo- it-yourself opera-
tionsº section.
Tire equipment
1. The SUMMER tires are of a tread design to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, Nissan rec-
ommends the use on all four wheels of
MUD & SNOW or ALL SEASON tires.
Please consult your Nissan dealer for the
tire type, size, speed rating and availability
information.
2. For additional traction on icy roads, studded
tires may be used. However, some Prov-
inces and States prohibit their use, so,
before installing studded tires, check local,
state and provincial laws.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
3. Snow chains may be used if desired. Make
sure they are of proper size for the tires on
your vehicle and are installed according to
the chain manufacturer's suggestions. Use
of tire chains may be prohibited according
to location. Check the local laws before

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:
To avoid the danger of being burned,
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.
1. Move the vehicle safely off the road, apply
the parking brake and move the gearshift
lever to the neutral position (automatic
transmission to ªPº).
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 ªmaximum
hotº and fan control to ªhigh speedº.
3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Wait until no
steam or coolant can be seen before pro-
ceeding.4. Open the engine hood.
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. 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
temperature gauge indication returns to
normal.
6. 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.
IBe careful not to allow your hands,
hair or clothing to come into contact
with, or to get caught in, the running
fan or belts.
IIf coolant is leaking, the cooling fan
belt is missing or loose or the cooling
fan does not run, stop the engine.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reservoir
tank if necessary. Have your vehicle re-
paired at the nearest NISSAN dealer.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution (anti-freeze/water mix-
ture ratio: 50/50) which will ensure protection
against freezing down to þ30ÉF (þ35ÉC). The
anti-freeze solution contains rust and corro-
sion inhibitors, therefore additional cooling
system additives are not necessary.
When adding or replacing the coolant,
be sure to use an ethylene glycol anti-
freeze with the proper mixture ratio of
50% anti freeze 50% soft water.

CHECKING COOLANT LEVEL
With coolant reservoir
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the ªMINº level, add coolant to the
ªMAXº level. If the reservoir tank is empty,
check the coolant level in the radiatorwhen
the engine is cold.If there is insufficient
coolant in the radiator, fill the radiator with
coolant up to the filler opening and also add it
to the reservoir tank up to the ªMAXº level.
