2-41Interior Lamps Instrument Panel Intensity Control The instrument panel intensity control is located to the
right of the exterior lamps control.
Turn the thumbwheel up to adjust the instrument panel
lights. To turn on the dome lamps (with the vehicle's
doors closed) turn the thumbwheel all the way up.
Exit Lighting With exit lighting, the interior lamps will come on when
you remove the key from the ignition. The lamps will
not come on if the DOME OVERRIDE button is
pressed in.
Illuminated Entry Your vehicle is equipped with an illuminated
entry feature.
When a door is opened, the dome lamps and puddle
lamps will come on if the DOME OVERRIDE button is
in the ªoutº position. If the DOME OVERRIDE button
is pressed in, the lamps will not come on. Front Reading Lamps (If Equipped) If your vehicle has reading
lamps, press the button
located next to the lamp to
turn them on. The lamps
can be adjusted to point in
the direction you want.
Press the button again to turn the lamp off.
Your vehicle may also have reading lamps in other
locations. To turn on or off, press the button located next
to the lamp. The lamps are fixed and cannot be adjusted.

3-5Mode Knob
- Automatic Operation
When the system is set in AUTO mode, sensors will
control the air delivery mode. Air will come primarily
from the floor or instrument panel outlets, with some air
directed to the windshield to prevent fogging.
When the system is in AUTO mode, the air conditioning
light will turn on, and the recirculation and outside air
lights will turn off. With the system in full automatic
control (both the fan and mode knobs in AUTO), you
still have the ability to override any function. However,
continually overriding the outside air or the A/C
compressor will limit the ability of the system to cool
the vehicle quickly.
If you push a button for a function which is not
available, the light next to that button will flash three
times to alert you that it's not available.
To find your comfort zone, start with the 74
F (23
C)
setting and allow about 20 minutes for the system to
adjust the temperature if necessary. With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the
need for heat, the airflow will be directed out the floor
outlets. As the interior temperature approaches a desired
setting, the fan speed will decrease. To maintain interior
comfort, the airflow will adjust between the instrument
panel outlets and floor outlets. On bright sunny days
in cool weather, the airflow may come out of the
instrument panel and the floor outlets (bi
- level mode)
to maintain comfort and prevent stuffiness.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the coolant
warms up, the fan speed will gradually increase and
air will flow from the floor outlets, with some airflow
to the windshield to prevent fogging under most
normal conditions.
Be careful not to put anything over the solar sensor
located near the center of the instrument panel.
This sensor is used by the automatic system to
regulate temperature.
