To replace the battery:
1. Separate the transmitter with aflat, thin object inserted into the
notch, located above the
metal base.
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
This feature allows you to start the
engine from outside of the vehicle.
It may also start up the vehicle's
heating or air conditioning systems
and rear window defogger. Normal
operation of the system will return
after the key is turned to the ON/
RUN position.
During a remote start, the climate
control system will default to a
heating or cooling mode depending
on the outside temperatures.
During a remote start, if the vehicle
has an automatic climate control
system and heated seats, the
heated seats will turn on during
colder outside temperatures and will
shut off when the key is turned to
ON/RUN. If the vehicle does not
have an automatic climate control
system, during remote start, you will
need to manually turn the heated
seats on and off. See Heated and
Ventilated Front Seats on page 3‑7
for additional information. Laws in some communities may
restrict the use of remote starters.
For example, some laws may
require a person using the 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 the vehicle is low on fuel. The
vehicle may run out of fuel.
If the vehicle has the remote start
feature, the RKE transmitter
functions will have an increased
range of operation. However, the
range may be less while the vehicle
is running.
There are other conditions which
can affect the performance of the
transmitter, see
Remote Keyless
Entry (RKE) System on page 2‑2 for
additional information.
/(Remote Start): This button will
be on the RKE transmitter if you
have remote start.

Engine Cooling System
Messages
ENGINE HOT A/C (Air
Conditioning) TURNED OFF
This message displays when the
engine coolant becomes hotter than
the normal operating temperature.
See
Engine Coolant Temperature
Gauge on page 5‑12. To avoid
added strain on a hot engine,
the air conditioning compressor
automatically turns off. When the
coolant temperature returns to
normal, the air conditioning
compressor turns back on. You can
continue to drive your vehicle.
If this message continues to appear,
have the system repaired by your
dealer as soon as possible to avoid
damage to the engine.

8-2 Climate Controls
O(Off):Press the driver side
temperature knob to turn the climate
control system off. Outside air still
enters the vehicle, and is directed to
the floor. This direction can be
changed by pressing the mode
button. The temperature can also be
adjusted using either temperature
knob. Press the up or down arrows
on the fan switch, the defrost button,
the AUTO button, driver side
temperature knob, or the air
conditioning button to turn the
system on when it is off.
Driver and Passenger Side
Temperature Knob
The driver and passenger side
temperature knobs are used to
adjust the temperature of the air
coming through the system on the
driver or passenger's side of the
vehicle. The temperature can be
adjusted even if the system is
turned off. This is possible since
outside air always flows through the system as the vehicle is
moving forward unless it is set to
recirculation mode. See
“Recirculation”
later in this section.
Turn the knob clockwise or
counterclockwise to increase or
decrease the cabin temperature.
The display will show the
temperature setting increasing
or decreasing.
Set the passenger's temperature
setting to match the driver
temperature setting by pressing the
passenger power knob.
When in defrost mode the
passenger temperature setting
cannot be changed.
Automatic Operation
AUTO (Automatic): When
automatic operation is active the
system will control the inside
temperature, the air delivery, and
the fan speed. Use the steps below to place the
entire system in automatic mode:
1. Press the AUTO button.
When AUTO is selected, the
display will change to show the
current temperature(s) and
AUTO will appear. The current
delivery mode and fan speed
will also be displayed for
approximately five seconds.
When AUTO is selected, the air
conditioning operation and air
inlet will be automatically
controlled. The air conditioning
compressor will run when the
outside temperature is over
about 4°C (40°F). The air inlet
will normally be set to outside
air. If it is hot outside, the air
inlet may automatically switch to
recirculate inside air to help
quickly cool down the vehicle.
The light on the button comes on
in recirculation.

8-4 Climate Controls
-(Defog):This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor
outlets, and side window vents. In
this mode, the system turns off
recirculation and runs the air
conditioning compressor unless the
outside temperature is close to
freezing. The recirculation mode
cannot be selected while in the
defog mode.
0(Defrost): This mode removes
fog or frost from the windshield
more quickly. Air is directed to the
windshield and side window vents,
with some directed to the floor
vents. In this mode, the system
automatically forces outside air
into the vehicle and runs the air
conditioning compressor unless the
outside temperature is close to
freezing. The recirculation mode
cannot be selected while in the
defrost mode. The passenger temperature control
cannot be activated while in defrost
mode. If the passenger control
knob is pressed, the passenger
temperature flashes three times
and will not work. If the passenger
control knob is adjusted, the driver
temperature indicator changes. The
passenger temperature will not be
displayed.
If vent, bi-level, or floor mode is
selected again, the climate control
system displays the previous
temperature settings.
Do not drive the vehicle until all the
windows are clear.
#(Air Conditioning):
Press to
turn the air conditioning (A/C)
compressor on and off. An indicator
light comes on to show that the air
conditioning is on. Pressing this button when the
outside temperature is too cool for
air conditioning will make the air
conditioning indicator flash three
times and then turn off indicating
the air conditioning mode is not
available. If the air conditioning is
on and the outside temperature
drops below a temperature which is
too cool for air conditioning to be
effective, the air conditioning light
turns off to show that the air
conditioning mode has been
canceled.
On hot days, open the windows long
enough to let hot inside air escape.
This helps to reduce the time it
takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.
The air conditioning system
removes moisture from the air, so a
small amount of water might drip
under the vehicle while idling or
after turning off the engine. This is
normal.

Climate Controls 8-5
@(Recirculation):Press to turn
the recirculation mode on or off. An
indicator light comes on to show
that the recirculation is on.
This mode recirculates and helps
to quickly cool the air inside the
vehicle. It can be used to help
prevent outside air and odors from
entering the vehicle.
The recirculation mode cannot be
used with floor, defog, or defrost
modes. If recirculation is selected
with one of those modes, the
indicator light flashes three times
and then turns off. The air
conditioning compressor also comes
on when this mode is activated.
While in recirculation mode the
windows may fog when the weather
is cold and damp. To clear the fog,
select either the defog or defrost
mode and increase the fan speed.
The recirculation mode can also be
turned off by turning off the ignition.Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
1(Rear Window Defogger):
Press to turn the rear window
defogger on or off. It automatically
turns off after it has been activated.
The defogger can also be turned off
by turning off the engine. Do not
drive the vehicle until all the
windows are clear.
Notice: Do not use a razor blade
or sharp object to clear the inside
rear window. Do not adhere
anything to the defogger grid
lines in the rear glass. These
actions may damage the rear
defogger. Repairs would not be
covered by your warranty. Heated Mirrors:
Press
1to help
clear fog or frost from the surface of
the outside mirror. See “Outside
Heated Mirrors” inHeated Mirrors
on page 2‑20.
Heated or Cooled Seats: For
vehicles with heated and cooled
seats, see Heated and Ventilated
Front Seats on page 3‑7.
