TACHOMETERThe tachometer indicates engine speed in revo-
lutions per minute (rpm).
CAUTION
When engine speed approaches the red
zone, shift to a higher gear. Operating
the engine in the red zone may cause
serious engine damage.
ENGINE COOLANT TEMPERATURE
GAUGEThe gauge indicates the engine coolant tem-
perature.
The engine coolant temperature will vary with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates engine coolant
temperature over the normal range,
stop the vehicle as soon as safely pos-
sible. If the engine is overheated, con-
tinued operation of the vehicle may se-
riously damage the engine. See “If your
vehicle overheats” in the “6. In case of

The engine oil pressure warning light is not
designed to indicate a low oil level. Use the
dipstick to check the oil level.See “Engine
oil” in the “8. Maintenance and do-it-yourself”
section.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Turn off the engine as
soon as it is safe to do so.
Low tire pressure warning light
(if so equipped)
The light comes on for about 1 second when the
ignition switch is turned ON, and then it turns off.
NISSAN’s low tire pressure warning system is a
tire pressure monitoring system. It monitors tire
pressure of all tires except the spare. When the
tire pressure monitoring system warning light is
lit, one or more of your tires is significantly
under-inflated. You should stop and check your
tires as soon as possible, and inflate them to theproper pressure as indicated on the vehicle’s tire
information placard. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire malfunction. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stop-
ping ability. Each tire, including the spare, should
be checked monthly when cold and set to the
recommended inflation pressure as specified in
the vehicle placard and Owner’s Manual.
The recommended inflation pressure may also
be found on the Tire and Loading Information
label.
If the vehicle is being driven with very low tire
pressure (lower than 28 psi), the light will illumi-
nate and the chime will sound for about 10
seconds.
For additional information, see “Low tire pres-
sure warning system” in the “5. Starting and
driving” section and “Flat tire” in the “6. In case
of emergency” section. You can check the tire
pressure of all 4 tires on the trip computer
display. See “Trip computer” earlier in this sec-
tion.
WARNING

If the light does not come on with theignition switch turned ON, have the
vehicle checked by a NISSAN dealer
as soon as possible.

If the light comes on while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location
and stop the vehicle as soon as pos-
sible. Serious vehicle damage could
occur and may lead to an accident
and could result in serious personal
injury. Check the pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Infor-
mation label to turn the low tire pres-
sure warning light OFF. If the light
still comes on while driving after ad-
justing the tire pressure, a tire may
be flat. If you have a flat tire, replace
it with a spare tire as soon as pos-
sible.

When a spare tire is mounted or a
wheel is replaced, tire pressure will
not be indicated and the low tire
pressure warning system will not

The exhaust system and body should
be inspected by a qualified mechanic
whenever:
•The vehicle is raised for service.
•You suspect that exhaust fumes
are entering into the passenger
compartment.
•You notice a change in the sound
of the exhaust system.
•You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.THREE WAY CATALYSTThe three way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the converter are burned at high tem-
peratures to help reduce pollutants.
WARNING

The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-mals or flammable materials away
from the exhaust system compo-
nents.

Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
CAUTION

Do not use leaded gasoline. Deposits
from leaded gasoline seriously re-
duce the three way catalyst’s ability
to help reduce exhaust pollutants.

Keep 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
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by a NISSAN
dealer.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three way catalyst.

Do not race the engine while warm-
ing it up.

Do not push or tow your vehicle to
start the engine.
LOW TIRE PRESSURE WARNING
SYSTEM (if so equipped)The low tire pressure warning system displays
pressure of all tires (except the spare tire) on the
trip computer by sending a signal from a sensor
that is installed in each wheel.
Tire pressure rises and falls depending on the
heat caused by the vehicle’s operation and the
outside temperature. Low outside temperature
can lower the temperature of the air inside the
tire which can cause a lower tire inflation pres-
sure. This may cause the low tire pressure
warning light to illuminate.
If the warning light illuminates in low ambient
temperatures as described above, check the tire
pressure for all four tires. Adjust the tire pressure
to the recommended COLD tire pressure shown

BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.Vacuum assisted brakesThe 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.Using the brakesAvoid 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

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.Wet brakesWhen 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 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)The anti-lock brake system controls the brakesat 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).

7. After starting your engine, carefully discon-
nect the negative cable and then the positive
cable.
8. Replace the vent caps (if so equipped). Be
sure to dispose of the cloth used to cover the
vent holes as it may be contaminated with
corrosive acid.Do not attempt to start the engine by pushing.
CAUTION

Automatic transmission models can-
not be push started. Attempting to do
so may cause transmission damage.

Three way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.

Never 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.
WARNING

Do not continue to drive if your ve-
hicle overheats. Doing so could
cause 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
N (Neutral) position (automatic transmission
to the P (Park) position).
Do not stop the engine.
2. Turn off the air conditioner switch. Open all

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. Wait until no steam
or coolant can be seen before proceeding.
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 to get caught in the
cooling fan, or drive belt.

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.When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must
be followed. Incorrect towing equipment could
damage your vehicle. Towing instructions are
available from a NISSAN dealer. Local service
operators are generally familiar with the appli-
cable laws and procedures for towing. To assure
proper towing and to prevent accidental damage
to your vehicle, NISSAN recommends having a
service operator tow your vehicle. It is advisable
to have the service operator carefully read the
following precautions.
WARNING

Never ride in a vehicle that is being
towed.

Never get under your vehicle after it
has been lifted by a tow truck.
CAUTION

When towing, make sure that the
transmission, axles, steering system
and powertrain are in working condi-TOWING YOUR VEHICLE

thoroughly with soap or hand cleaner
as soon as possible.

Keep coolant out of reach of children
and pets.
1. Open radiator drain plug at the bottom of
radiator, and remove radiator filler cap.

Be careful not to allow coolant to con-
tact drive belts.

Waste coolant must be disposed of
properly. Check your local regulations.
2. Close the radiator drain plug securely after
the coolant is drained.3. Fill the radiator slowly with the proper mixture
of anti-freeze solution and demineralized
water/distilled water. Fill the reservoir tank up
to the MAX level. Then install the radiator filler
cap.
4. Start the engine and warm it up until it
reaches normal operating temperature. Then
race the engine 2 or 3 times under no load.
Watch the engine coolant temperature
gauge for signs of overheating.
5. Stop the engine. After it completely cools
down, refill the radiator up to the filler open-
ing. Fill the reservoir tank up to the MAX level.
