2-57 Anti-Lock Brake System Warning Light
United States Canada
The anti
-lock brake system warning light should come on
for a few seconds when you turn the ignition key to RUN.
If the anti
-lock brake system warning light stays on longer
than normal after you've started your engine, turn the
ignition off. Or, if the light comes on and stays on when
you're driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again while
you're driving, the anti
-lock brake system needs service
and you don't have anti
-lock brakes. The brake pedal may
be harder to push, or it may go to the floor. It may take
longer to stop. Adjust your driving accordingly.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Enhanced Traction System Warning Light
(3100 V6 Engine)
The Enhanced Traction System warning light may come
on for the following reasons:

If you turn the system off by shifting to
SECOND (2) or FIRST (1), the warning light will
come on and stay on. To turn the system back on,
shift to THIRD (3) or AUTOMATIC
OVERDRIVE (
). See ªEnhanced Traction
Systemº in the Index.

If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service. Adjust your driving accordingly.

On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI
-LEV and set the temperature levers to a
comfortable setting. The system will bring in outside air
and direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice this
temperature difference more at some times than others.
Push the A/C button on for cooling.
Dual Automatic ComforTemp Climate
Control (If Equipped)
With this system, you set a temperature. You can
then either let the system automatically control airflow
direction and force to maintain the temperature, or you
can manually adjust it. The system works best if you
keep your windows closed while using it.Automatic Control
For the most efficient operation, you should set the
system temperature and press AUTO. The system will
select the best fan speed and airflow settings to keep you
comfortable. The air conditioning compressor will run if
the outside temperature is above 40
F (4
C). You may
notice a delay of two to three minutes before the fan
comes on at start up in cool weather.
Temperature Control
The TEMP switch sets the temperature for the entire
system when the light on the DUAL button isn't lit.
If the DUAL button light is lit, this master temperature
control sets the temperature for the driver only. Press the
up arrow to raise the temperature and press the down
arrow to lower the temperature. The display will show
your selection for a few seconds, then the outside
temperature will be displayed. If you push the AUTO
button, the system will control the fan speed and airflow.
The driver's temperature and passenger's temperature
settings will be automatically maintained even if manual
overrides have been selected except for settings at 60
F
(15
C) and 90
F (32
C).
Setting the temperature to 90
F (32
C) will lock control in
full hot, direct air to the floor, and increase the fan speed to
high. The system will not return to automatic temperature
control until the temperature setting is lowered.

3-5
Setting the temperature to 60
F (15
C) will lock control
in full cold, recirculate interior air, direct air to outlets
on panel and increase blower speed to high. The system
will not return to automatic temperature control until the
temperature setting is raised.
Passenger's Temperature Control
The PASSENGER CONTROL buttons with the arrows
adjust the temperature on the passenger's side so it is
warmer or cooler than the temperature for the driver's
side. Push the DUAL button so that the indicator light is
lit. Press the right arrow button to raise the temperature.
Press the left arrow button to lower the temperature.
The display will not show the passenger's temperature,
only that of the driver. Indicators in the passenger
control section will show passenger's side temperature
relative to the driver's set temperature.

The amber light indicates the same temperature as
set for the driver.

The red lights indicate a warmer temperature than
that of the driver.

The blue lights indicate a cooler temperature than
that of the driver.Hot Weather Example: When you start the vehicle in
hot weather, 80F (27C) or after being parked during
the day in full sun, if your driver set temperature is 75F
(23C) and you are in full automatic mode, the system
will automatically move the temperature to full cold.
The fan will be at low speed momentarily and then go
to the high speed. The air intake will be recirculated for
maximum cooling performance. As the interior of the
vehicle cools down to your desired comfort point, the fan
speed will decrease and the temperature will move to a
warmer position to maintain your desired comfort. As the
interior cools down or the sun load decreases the system
could switch to air delivered to A/C vents and the floor.
Cold Weather Example: When you start the vehicle in
cold weather, (below freezing) or after being parked
overnight. If your Driver Set Temperature is 75F (23C)
and you are in Full Automatic mode, the system will
automatically move the temperature doors to full hot.
The fan will start out at a low speed and will increase to
a higher speed as the engine warms up. The air will be
delivered to the floor. As the interior of the vehicle
warms up to your desired comfort point, the fan speed
will decrease and the temperature will move to a cooler
position to maintain your desired comfort. As the cabin
warms up or the sun load increases the system could
switch to air delivered to the windshield and the floor
(DEFOG mode).
