2003 NISSAN MAXIMA heating

WARNING
IThe air conditioner cooling function
operates only when the engine is run-
ning.
IDo not leave children, impaired
adults, or pets alone in your vehicle.
On hot, sunny days, temperatures in
a closed vehicle could quickly be-
come high enough to cause severe or
possibly fatal injuries to people oranimals.
IDo not use the recirculation mode for
long periods as it may cause the
interior air to become stale and the
windows to fog up.
IPositioning of the heating or air con-
ditioning controls should not be done
while driving, so full attention may be
given to vehicle operation.

Operating tipsIKeep the windows and sun roof closed
while the air conditioner is in operation.
IAfter parking in the sun, drive for 2 or 3
minutes with the windows open to vent hot
air from the passenger compartment. Then,
close the windows. This will allow the air
conditioner to cool the interior more quickly.
IThe air conditioning system should be
operated for about 10 minutes at least
once a month. This helps prevent dam-
age to the system due to lack of lubrica-
tion.
IIf the coolant temperature gauge exceeds
the HOT position, turn the air conditioning
off. For additional information, see ªIf your
vehicle overheatsº in the ª6. In case of
emergencyº section.AIR FLOW CHARTSThe charts on the following pages show the
button and lever positions formaximum and
quickheating, cooling or defrosting.
The air recirculation button should be in
the OFF position for normal cooling, heat-
ing and defrosting.4-6

BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, 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 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 road

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.
