1999 NISSAN MAXIMA engine overheat

ENGINE COOLANT
TEMPERATURE GAUGEThe gauge indicates the engine coolant tem-
perature.
The engine coolant temperature will vary with
the outside air temperature and driving condi-
tions.
If the gauge indicates engine coolant
temperature over the normal range, stop
the vehicle as soon as safely possible. If
the engine is overheated, continued op-
eration of the vehicle may seriously
damage the engine. See ªIf your vehicle
overheatsº in the ª6. In case of emer-
gencyº section.
FUEL GAUGEThe gauge indicates the approximate fuel level
in the tank.
The gauge may move slightly during braking,
turning, acceleration, or going up or down hill.
The gauge needle is designed to remain in
approximately the same position, even when
the ignition key is turned OFF.
Refill the fuel tank before the gauge regis-
ters Empty.

The front seats are warmed by built-in heaters.
The switches located on the center console
can be operated independently of each other.
1. Start the engine.
2. Select heat range.
IFor low heat, press the top of the switch.
IFor high heat, press the bottom of the
switch.
IFor no heat, the switch has a center OFF
position between low and high.
The indicator light in the switch will illumi-
nate when low or high is selected.The heater is controlled by a thermostat,
automatically turning the heater on and off.
The indicator light will remain on as long as
the switch is on.
3. When the vehicle's interior is warmed, or
before you leave the vehicle, be sure to turn
the switch off.
IThe battery could run down if the seat
heater is operated while the engine is
not running.
IDo not use the seat heater for ex-
tended periods or when no one is
using the seat.
IDo not put anything on the seat which
insulates heat, such as a blanket,
cushion, seat cover, etc. Otherwise,
the seat may become overheated.
IDo not place anything hard or heavy
on the seat or pierce it with a pin or
similar object. This may result in
damage to the heater.
IAny liquid spilled on the heated seatshould be removed immediately with
a dry cloth.
IWhen cleaning the seat, never use
benzine, thinner, or any similar mate-
rials.
IIf any abnormalities are found or the
heated seat does not operate, turn
the switch off and have the system
checked by your NISSAN dealer.

IThe exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust pipe.
IDo not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.IDo not use leaded gasoline. Deposits
from leaded gasoline seriously re-
duce the three way catalyst's ability
to help reduce exhaust pollutants.
IKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over-
rich fuel flow into the three way cata-
lyst, 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 an authorized
NISSAN dealer.
IAvoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three way catalyst.
IDo not race the engine while warming
it up.
IDo not push or tow your vehicle to
start the engine.
AVOIDING COLLISION AND
ROLLOVERFailure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden steer-
ing maneuvers, because these driving prac-
tices could cause you to lose control of your
vehicle.As with any vehicle, a loss of con-trol could result in a collision with other
vehicles or objects, or cause the vehicle to
rollover, particularly if the loss of control
causes the vehicle to slide sideways.Be
attentive at all times, and avoid driving when
tired. Never drive when under the influence of
alcohol or drugs (including prescription or
over-the-counter drugs which may cause
drowsiness). Always wear your seat belt. See
ªSeat Beltsº in the ª1. Seats, restraints and
supplemental air bag systemsº section. And
also instruct your passengers to do so.
DRINKING ALCOHOL/DRUGS AND
DRIVINGNever drive under the influence of alco-
hol or drugs. Alcohol in the bloodstream
reduces coordination, delays reaction
time and impairs judgment. Driving after
drinking alcohol increases the likeli-
hood of being involved in an accident
injuring yourself and others. Addition-
ally, if you are injured in the accident,
alcohol can increase the severity of the
injury.

The brake system has two separate hydraulic
circuits. If one circuit develops a problem, you
will still have braking at two wheels.
Vacuum assisted brake
The brake booster aids braking by using en-
gine 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 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.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This overheats the brakes, in-
creases 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 anddownshift 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.
IWhile driving on a slippery surface,
be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.
IIf 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)
(if so equipped)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 systemDepress the brake pedal and hold it down.Do not pump the brake pedal. Doing so
may result in increased stopping
distances.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 pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.

Self-test featureThe 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 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
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 at
your 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 thatthe 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 of tires may also
affect braking effectiveness.
IWhen replacing tires, install the
specified size of tires on all four
wheels.
IWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. See ªVe-
hicle identificationº in the ª10. Tech-
nical and consumer informationº sec-
tion for tire placard location.
On slippery surfaces such as wet asphalt
roads, vehicle wheels may spin when the
vehicle is accelerated. This wheel spin re-
duces acceleration, or causes the vehicle to
swerve, thus decreasing vehicle stability.
The traction control system helps limit wheel
spin on slippery roads. The system operates
only if it senses one or both of the front wheels
spinning or beginning to lose traction. When
this happens, the system reduces engine
power and may also upshift the transmission
to help limit wheel spin.
IIndicator light
If a malfunction occurs in the traction con-
trol system, the SLIP and
indicator
lights come on in the meter panel.
As long as these warning lights are on, the
traction control function is canceled. The
vehicle will behaves like a model without
the traction control system.
IThe traction control system is most
effective when the transmission gear
selector is in the D position.
IIf you drive in gear 1 or 2 with the TCS
on, this could cause the three way
catalyst to overheat and be damaged.TRACTION CONTROL SYSTEM (if

IDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
ITo avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
IDo 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 trans-
mission 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 hotand 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
temperature 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 pro-
ceeding.
5. Open the engine hood.
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.
IBe 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.
IThe fan motor can start at any time
when the coolant temperature is high.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. The anti-freeze solu-
tion contains rust and corrosion inhibitors,
therefore additional cooling system additives
are not necessary.When adding or replacing coolant, be
sure to use only a genuine NISSAN anti-
freeze coolant or equivalent with the
proper mixture ratio of 50% anti-freeze
and 50% demineralized water/distilled
water. The use of other types of coolant
solutions may damage your engine
cooling system.Outside temperature

CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below MIN, add coolant up to the MAX 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
MAX level.
If the engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.
