2-70 Trunk Ajar Light (If Equipped)
This light comes on if your
vehicle's trunk is not
completely closed.
Fuel Gage
Standard Cluster Gage Cluster
Your fuel gage shows about how much fuel is in your
tank. It works only when the engine is on. When the
indicator nears EMPTY (E), you still have a little fuel
left. You need to get more fuel right away.Here are some things that some owners ask about. None
of these show a problem with your fuel gage:

At the service station, the gas pump shuts off before
the gage reads FULL (F).

It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank's capacity to fill
the tank.

The gage moves a little when you turn a corner,
speed up, or make a hard stop.

The gage doesn't go back to EMPTY (E) when you
turn off the ignition.
Low Fuel Warning Light (If Equipped)
If your vehicle has the gage
cluster, a light near the fuel
gage will turn on when you
are low on fuel. You should
get more fuel as soon as
you can.

VENT: This setting directs outside air through the
middle instrument panel outlets. The air conditioning
compressor is not working when VENT is selected.
HTR: This button directs air out of the heater outlets.
Most of the air will come from the floor outlets while
some air will flow through the windshield and side
window outlets. The air conditioning compressor is not
working when HTR is selected.
BLEND: When BLEND is selected, the airflow will be
split between the windshield and the floor outlets. The
air conditioning compressor will be operating.
FRONT: This setting directs most of the airflow toward
the windshield.
OFF: The ventilation system always allows fresh air to
flow through your vehicle when it is moving. The
system will try to keep the air at a previously chosen
temperature. When the system is off, the blower fan is
also off.
MAX: This setting directs airflow through the middle
instrument panel outlets. The amount of outside air
entering your vehicle is limited with this setting. The air
conditioning compressor is on in this mode.NORM: This setting cools the outside air entering your
vehicle and directs it through the middle instrument
panel outlets. The air conditioner is on in this mode.
BI
-LEV: This setting directs warm air to the floor and
cooler air to the middle instrument panel outlets. The air
conditioner is on in this mode.
Dual Automatic Comfortemp
Climate Control (If Equipped)
If your vehicle has the Dual Automatic Comfortemp
Climate Control option, the following information tells
you how it works.
You will hear a beep each time a button is pushed and a
light on the button will indicate which function is active.
The lights are on all buttons except TEMP, FAN and
AIR FLOW. The display will show fan speed, comfort
level setting and airflow direction for a few seconds
whenever AUTO is selected, and then it will display the
outside temperature. The outside temperature reading is
most accurate when the vehicle is moving. During stops,
the display shows the previous temperature for best
accuracy and system control.

On sunny days, when the air is moderately warm or
cool, use BI
-LEV to deliver warm air to the floor and
cooler air to the middle instrument panel outlets. On
days like these, the sun may adequately warm your
upper body, but your lower body may not be warm
enough. To warm or cool the air delivered, adjust the
TEMPERATURE lever.
The amount of fresh air entering the vehicle is limited
when RECIRC is selected. This is helpful when you are
trying to cool the air in your vehicle or limit the air
entering the vehicle.
If your vehicle has the Dual Automatic Comfortemp
system and it is set for AUTO, on very hot days, the
system will automatically enter the RECIRC mode and
the temperature door will be positioned at the full cold
position for maximum cooling. If the system is not in
the AUTO mode, RECIRC should be selected to provide
maximum cooling. You can choose the extreme comfort
setting of 60
F (16
C), but the system will not cool any
faster by choosing the extreme comfort setting.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle's engine speed and
power. This is normal because the system is designed to
cycle the compressor on and off to keep the
desired temperature.Heating
If your vehicle has the electronic touch system, on
cold days, use HTR with the TEMPERATURE lever
toward WARM.
If your vehicle has the Dual Automatic Comfortemp
system, and on cold days, if the AUTO mode is selected,
the system will automatically direct the air toward the
floor and the temperature door will be positioned at the
full hot position. You can choose the extreme comfort
setting of 90
F (32
C) but the system will not warm up
any faster by selecting the extreme comfort setting. If
the outside temperature is cold, the fan will be delayed
to avoid blowing cold air. Pushing the FAN, AIR FLOW
or FRONT buttons will override this delay, turn off the
AUTO mode and change the fan speed.
With each system, outside air will be brought in and sent
through the floor outlets. The heater works best if you
keep your windows closed while using it.
