2004 NISSAN ALTIMA sensor

Air flow control
Pushing the manual air flow control button se-
lects the air outlet to:
— Air flows from center and side
ventilators.
— Air flows from center and side
ventilators and foot outlets.
— Air flows mainly from foot outlets.
— Air flows from defroster and foot
outlets.
To turn system off
Push the OFF button.
OPERATING TIPS
cWhen the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is
not a malfunction. After the coolant tempera-
ture warms up, air flow from the foot outlets
will operate normally.The sunload sensor, located on the top passen-
ger side of the instrument panel, helps the system
maintain a constant temperature. Do not put any-
thing on or around this sensor.The air conditioner system in your NISSAN ve-
hicle is charged with a refrigerant designed with
the environment in mind.
This refrigerant does not harm the earth’s
ozone layer.
Special charging equipment and lubricant is re-
quired when servicing your NISSAN air condi-
tioner. Using improper refrigerants or lubricants
will cause severe damage to your air conditioner
system. See “Air conditioner system refrigerant
and lubricant recommendations” in the “Techni-
cal and consumer information” section of this
manual.
A NISSAN dealer is able to service your “environ-
mentally friendly” air conditioning system.WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper equipment.

When driving, the anti-lock brake system con-
trols the wheels so they will not lock when brak-
ing abruptly or when braking on a slippery road.
Thus, difficult steering and swerving of the ve-
hicle due to locked wheels is minimized. The
system detects the wheel rotation rate and elec-
tronically controls the pressure applied to each
brake. Slight vibration on the brake pedal accom-
panied by noise usually occurs while the ABS
system is operating. Such vibration and noise
encountered during abrupt braking is not a prob-
lem, but indicates that the system is functioning
properly. However, the pulsation may indicate
that road conditions are hazardous and extra care
is required while driving.
Self-test feature
The anti-lock brake system consists of electronic
sensors and hydraulic solenoids controlled by a
computer. The computer 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 pulsa-
tion 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 brake
warning light on the instrument panel. The brake
system then operates normally, but without anti-
lock assistance.If a malfunction occurs in the system, the anti-
lock function will not operate, but the standard
vehicle brake system will continue to operate
normally. The ABS brake warning light will then
come on.
If the light comes on during the self-test or while
driving, take the vehicle to a NISSAN dealer for
repair.
WARNING
cThe 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 brake
system. Stopping distances may also
be longer on rough, gravel or snow cov-
ered roads, or if you are using tire
chains. Tire type and condition may also
affect braking effectiveness. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the re-
sponsibility for safety of self and others
rests in the hands of the driver.cTire type and condition of tires may also
affect braking effectiveness.
cWhen replacing tires, install the speci-
fied size of tires on all four wheels.
cWhen installing a spare tire, make sure
it is the proper size and type as speci-
fied on the tire placard. For tire placard
location information, refer to “Tire plac-
ard” in the “Technical and consumer
information” section of this manual.
cRefer to “Wheels and tires” in the
“Maintenance and do-it-yourself” sec-
tion of this manual.

When accelerating on slippery surfaces the tire
may spin or slip. With the vehicle traction control
system, sensors detect these movements and
control the braking and engine output to help
improve vehicle stability while accelerating.
cWhen the traction control system is operat-
ing, the slip indicator in the instrument panel
blinks.
cIf the slip indicator blinks, the vehicle is un-
der slippery conditions. Be sure to drive
carefully. See “Slip indicator light” and “Trac-
tion control off indicator light” in the “Instru-
ments and controls” section of this manual.
cIf a malfunction occurs in the system,
the
andindicator lights
come on in the meter panel.
As long as these warning lights are on, the trac-
tion control function is canceled. The vehicle will
behave like a vehicle without the system.
WARNING
cThe traction control system is designed
to help improve driving stability but
does not prevent accidents due to
abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful when
driving and cornering on slippery sur-
faces and always drive carefully.
cIf brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the traction control system
may not operate properly and the
indicator light may come on.
cDo not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs and bushings
are not standard equipment or are ex-
tremely deteriorated, the traction con-
trol system may not operate properly
and the
indicator light may come
on.cWhen driving on extremely inclined sur-
faces such as higher banked corners,
the traction control system may not op-
erate properly and the
indicator
light may come on. Do not drive on
these types of roads.
cIf wheels or tires other than the recom-
mended ones are used, the traction
control system may not operate prop-
erly and the
indicator light may
come on.
cThe traction control system is not a sub-
stitute for winter tires or tire chains on a
snow covered road.
