3. Insert the new battery, positiveside facing down. Replace with a
CR2032 or equivalent battery.
4. Snap the transmitter back together.
Remote Vehicle Start
If available, 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.
If the vehicle has an automatic
climate control system, the climate
control system will default to a
heating or cooling mode depending
on the outside temperatures. If the
vehicle does not have an automatic
climate control system, the system
will turn on at the setting the vehicle
was set to when the vehicle was
last turned off. 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,
manually turn the heated seats on
and off. See
Heated Front Seats on
page 3‑9 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 the
vehicle has remote start.
To start the vehicle using the remote
start feature:
1. Aim the transmitter at the vehicle.
2. Press and release
Q. The
vehicle's doors will lock.
Immediately press and hold
/
until the turn signal lamps flash.
If you cannot see the vehicle's
lamps, press and hold
/for
two to four seconds. Pressing
/
again after the vehicle has
started will turn the engine off.

8-2 Climate Controls
Temperature Control:Move the
thumbwheels up or down to
increase or decrease the
temperature on the driver side
or the passenger side of the vehicle
for the dual zone system.
9(Fan Control): Turn the left
knob clockwise or counterclockwise
to increase or decrease the fan
speed. Turn the knob all the way
counterclockwise to turn the front
system off.
Air Delivery Mode Control: Turn
clockwise or counterclockwise to
change the airflow direction inside
the vehicle. By positioning the knob
between two modes, a combination
of those modes is selected.
Select from the following modes:
H(Vent): Air is directed to the
instrument panel outlets.
)(Bi-Level): Air is divided
between the instrument panel and
floor outlets. Some air is directed
towards the windshield and side
window outlets. Cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
6(Floor): Air is directed to the
floor outlets, with some of the air
directed to the windshield, side
window, and second row floor
outlets. In this mode, the system
automatically selects outside air.
Recirculation cannot be selected
when in Floor Mode.
-(Defog): The defog mode is
used to clear 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): The defrost mode is
used to remove 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. The recirculation
mode cannot be selected while in
the defrost mode. The air
conditioning compressor runs
automatically in this setting, unless
the outside temperature is close to
freezing.
Do not drive the vehicle until all the
windows are clear.
#(Air Conditioning): Press this
button to turn the air conditioning
system on or off. An indicator light
comes on to show that the air
conditioning is on. The air
conditioning can be selected in any
mode as long as the fan switch
is on.

Climate Controls 8-3
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.
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.
h(Recirculation):Press this
button to turn the recirculation mode
on or off. An indicator light comes
on to show that 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, defrost, or defogging
modes. If recirculation is selected
while in one of those modes, the
indicator flashes three times and
turns off. The air conditioning compressor will also come 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 engine.
REAR:
Press to turn the rear
heating and air conditioning on. See
Rear Climate Control System (Rear
Climate Control Only) on page 8‑10
or Rear Climate Control System
(Rear Climate with Rear Seat Audio)
on page 8‑11 for more information.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
<(Rear Window Defogger):
Press this button to turn the rear
window defogger on or off. The
system automatically turns off
several minutes 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.
For vehicles with heated outside
rearview mirrors, the mirrors will
heat to help clear fog or frost from
the surface of the mirror when the
rear window defog button is
pressed.
Notice:
Do not use anything
sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs would not be covered
by the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal, or anything
similar to the defogger grid.
