Battery Replacement
Replace the battery if the KEY FOB BATT LOW
message displays in the DIC. See “KEY FOB BATT
LOW” underDIC Warnings and Messages on page 3-46.
Notice:When replacing the battery, do not touch
any of the circuitry on the transmitter. Static
from your body could damage the transmitter.
To replace the battery:
1. Separate the transmitter with a at, thin object
inserted into the notch on the side.
2. Remove the old battery. Do not use a metal object.3. Insert the new battery, positive side facing up.
Replace with a CR2032 or equivalent battery.
4. Snap the transmitter back together.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine from outside
the vehicle. It may also start the vehicle’s heating or air
conditioning systems and rear window defogger. When
the remote start system is active and the vehicle has an
automatic climate control system, it will automatically
regulate the inside temperature. Normal operation of
the system will return after the ignition key is turned
to ON/RUN.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require
a person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time.

speed. The fan must be on to run the air conditioning
compressor.
Temperature Control:Turn the knob clockwise or
counterclockwise to increase or decrease the
temperature inside the vehicle.
When it is cold outside 0°F (−18°C) or lower, use the
engine coolant heater, if the vehicle has one, to quickly
provide warmer air. An engine coolant heater warms
coolant that the engine uses to warm the inside of the
vehicle. For more information, seeEngine Coolant
Heater on page 2-25.
Air Delivery Mode Control:Turn the knob clockwise
or counterclockwise to change the air delivery settings.
Select from the following modes:
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level):Air is divided between the air to the
instrument panel and oor outlets. Some air may
be directed toward the side windows.
3-20

6(Floor):Air is directed to the oor outlets with some
air directed to the side window outlets and windshield.
-(Defog):This mode clears the windows of fog
or moisture. Air is directed to the windshield and oor
outlets, with some air directed to the side windows.
When this mode is selected, the system automatically
turns off recirculation and tuns the air conditioning
compressor unless the outside temperature is at
or below freezing. The air conditioning compressor
operates although the indicator light is not on.
The air conditioning indicator light turns off when defog
is selected. If the air conditioning button is pressed
while in defog mode, the indicator light turns on.
If the button is pressed again, the light turns off.
The recirculation mode cannot be selected while in
the defog mode. Do not drive the vehicle until all the
windows are clear.
1(Defrost):This mode clears the windshield of fog or
frost more quickly. Air is directed to the windshield,
with some air directed to the oor vents. In this mode,
the system automatically forces outside air into thevehicle. The air conditioning compressor runs unless the
outside temperature is at or below freezing. The air
conditioning compressor operates although the indicator
light is not on. The air conditioning indicator light
turns off when defrost is selected. If the air conditioning
button is pressed while in defrost mode, the indicator
light turns on. If the button is pressed again, the light
turns off. Recirculation cannot be selected while in the
defrost mode.
To help clear the windshield quickly, do the following:
1. Select the defrost mode.
2. Select the highest temperature.
3. Select the highest fan speed.
:(Outside Air):Press the right side of the button to
turn the outside air mode on. An indicator light comes
on to show that it is on. Air from outside the vehicle
circulates throughout the vehicle. The outside air mode
can be used with all modes, except the recirculation
mode. Press
:again to cancel the recirculation mode.
3-21

?(Recirculation):Press the left side of the button
to turn the recirculation mode on. An indicator light
comes on to show that it is on. The air inside the vehicle
is recirculated through the climate control system and
throughout the vehicle, not from outside. This helps
to limit the odors entering the vehicle and maximize air
conditioning performance. The indicator light ashes
three times if you try to use recirculation in a mode that
it can not be used in. Use this mode only when it is
needed for comfort, since window fogging occurs if the
air conditioning compressor is not engaged.
Press
?to cancel the outside air mode. When you
switch to the defog or defrost modes the system
automatically moves from recirculation to outside air.
When the vehicle or fan is turned off and back on,
the system automatically defaults to outside air.
#(Air Conditioning):Press to turn the air conditioning
system on or off. An indicator light comes on to
indicate that the air conditioning is on.
The air conditioning system removes moisture from the
air, so sometimes a small amount of water drips
under the vehicle while it is idling or after the engine is
turned off. This is normal.
Maximum Air Conditioning
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the
Cvent mode.
2. Select the highest fan speed.
3. Select
#air conditioning.
4. Select the
?recirculation mode.
5. Select the coolest temperature.
Using these settings together for long periods of time
can cause the air inside of the vehicle to become
too dry. To prevent this from happening, after the air in
the vehicle has cooled, turn the recirculation mode off.

the vehicle and maximize air conditioning performance.
The recirculation mode cannot be used while in
defrost, defog, or oor mode. If recirculation is selected
while in these modes, the indicator light ashes three
times to let you know that it is not allowed. Use this
mode only when it is needed for comfort, since window
fogging occurs if the air conditioning compressor is
not engaged.
Press
?to cancel the auto recirculation feature.
Each time the vehicle is started, the system reverts to
the auto recirculation function.
When the weather is cool or damp, operating the
system in recirculation for extended periods of time can
cause fogging of the vehicle’s windows. To clear the
fog, select either defog or defrost. Make sure the
air conditioning is on.
#(Air Conditioning):Press to turn the air conditioning
on or off. A light above the button comes on while the
air conditioning is on.

When air conditioning is selected or in AUTO mode, the
system runs the air conditioning automatically to cool
and dehumidify the air entering the vehicle.
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for
the vehicle to cool down. Then keep the windows closed
for the air conditioner to work its best.
On cool, but sunny days while using manual operation
of the automatic system, use bi-level to deliver warm
air to the oor and cooler air to the instrument
panel outlets. To warm or cool the air, press
xorwto
the desired temperature setting.
In AUTO mode the system cools and dehumidies the
air inside the vehicle. Also, the system maximizes
its performance by using recirculation as necessary.
Heating:On cold days when using manual operation of
the automatic system, choose oor mode to deliver
air to the oor outlets. To warm or cool the air delivered,
adjust the temperature to the desired setting.
To use the automatic mode, turn the knob to AUTO and
adjust the temperature by pressing
xorw.

or off. An indicator light above the button comes on
to indicate that the rear window defogger is on.
If driving below 50 mph (80 km/h), the rear window
defogger turns off about 15 minutes after the button is
pressed. If turned on again, the defogger only runs
for about seven and one-half minutes before turning off.
If the vehicle’s speed is maintained above 50 mph
(80 km/h), the rear window defogger remains on once
the button is pressed.
If the vehicle has the remote start feature, the rear
defogger automatically turns on if it is cold outside,
but the indicator light does not come on. When
the vehicle transitions out of remote start mode the rear
defogger turns off.

If Steam Is Coming From The Engine
Compartment
{CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Turn it off and get everyone away from the
vehicle until it cools down. Wait until there is no sign
of steam or coolant before you open the hood.
If you keep driving when the vehicles engine is
overheated, the liquids in it can catch re. You or
others could be badly burned. Stop the engine if it
overheats, and get out of the vehicle until the
engine is cool.
SeeOverheated Engine Protection Operating Mode
on page 5-39for information on driving to a safe
place in an emergency.
If No Steam Is Coming From The
Engine Compartment
If an engine overheat warning is displayed but no steam
can be seen or heard, the problem may not be too
serious. Sometimes the engine can get a little too hot
when the vehicle:
Climbs a long hill on a hot day.
Stops after high-speed driving.
Idles for long periods in traffic.
Tows a trailer.
If the overheat warning is displayed with no sign of
steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and
to the highest fan speed. Open the windows as
necessary.
3. In heavy traffic, let the engine idle in N (Neutral)
while stopped. If it is safe to do so, pull off the road,
shift to P (Park) or N (Neutral) and let the engine idle.
If the temperature overheat gage is no longer in the
overheat zone or an overheat warning no longer displays,
the vehicle can be driven. Continue to drive the vehicle
slow for about 10 minutes. Keep a safe vehicle distance
from the car in front of you. If the warning does not come
back on, continue to drive normally.
