overheating NISSAN MAXIMA 2001 A33 / 5.G Owners Manual

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
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)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, thesystem 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.
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). 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 roadconditions 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.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-

WARNING
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 hot
and fan control to high speed.
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.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. 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
IBe careful not to allow your hands,
hair, jewelry or clothing to come intocontact with, or to get caught in the
cooling fan, or drive belt.
IThe engine cooling fan can start at
any time when the coolant tempera-
ture is high.
6. 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.

6. Start the engine, and warm it up until the
radiator fan operates. Then race the engine
two or three times under no load. Watch the
coolant temperature gauge for signs of
overheating.
7. 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.
8. Check the radiator drain plug and the drain
plug on the engine block for any sign of
leakage.
CHECKING ENGINE OIL LEVEL1. Park the vehicle on a level surface and
apply parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.

Octane rating tipsIn most parts of North America, you should use
unleaded gasoline with an octane rating of at
least 87 or 91 AKI (Anti-Knock Index) number.
However, you may use unleaded gasoline with
an octane rating as low as 85 AKI number in
these high altitude areas [over 4,000 ft (1,219
m)] such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada, south-
ern Idaho, western South Dakota, western
Nebraska, and that part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may
cause excessive fuel consumption or damage
to the engine. If any of the above symptomsare encountered, have your vehicle checked at
a NISSAN dealer or other competent service
facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.10-4

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.
IAlways secure items in the trailer to prevent
load shifts while driving.
IBe certain your rear view mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing be-
fore driving the vehicle.
Trailer towing tipsIn order to gain skill and an understanding of
the vehicle's behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability, and
braking performance will be somewhat differ-
ent than under normal driving conditions.
IAlways secure items in the trailer to prevent
load shift while driving.
IAvoid abrupt starts, acceleration or stops.
IAvoid sharp turns or lane changes.
IAlways drive your vehicle at a moderate
speed.
IAlways block the wheels on both vehicle
and trailer when parking. Parking on aslope is not recommended; however, if you
must do so, and if your vehicle is equipped
with automatic transmission, first block the
wheels and apply the parking brake, and
then move the transmission selector lever
into the P (Park) position. If you move the
selector lever to the P (Park) position be-
fore blocking the wheels and applying the
parking brake, transmission damage could
occur.
IWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift
the transmission to a lower gear and reduce
speed to reduce chances of engine over-
loading and/or overheating.
IIf the engine 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 windows, switching the fan
control to high and setting the temperature
control to the HOT position.
ITrailer towing requires more fuel than nor-
mal circumstances.
IAvoid towing a trailer for the first 500 miles
(800 km).
IHave your vehicle serviced more often thanat intervals specified in the recommended
maintenance schedule.
IWhen making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
ICrosswinds and rough roads will 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 immediately (but gradually) re-
duce vehicle speed. This combination will
help stabilize the vehicle. Never increase
speed.
IBe careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember the length of the trailer
must also pass the other vehicle before you
can safely change lanes.
ITo maintain engine braking efficiency and
electrical charging performance, do not use
fifth gear (manual transmission) or over-
drive (automatic transmission).10-18
