is lost or stolen, a replacement can be purchased
through your dealer/retailer. All transmitters need to be
re-coded to match the new transmitter.The lost transmitter will no longer work after the new
transmitters are re-coded. The vehicle can have a
maximum of eight transmitters matched to it. See
“Relearn Remote Key” underDIC Operation and
Displays (With DIC Buttons) on page 3-57orDIC
Operation and Displays (Without DIC Buttons) on
page 3-63for instructions on how to match RKE
transmitters to your vehicle.
Battery Replacement
Replace the battery if the REPLACE BATTERY IN
REMOTE KEY message displays in the DIC. See
“REPLACE BATTERY IN REMOTE KEY” underDIC
Warnings and Messages on page 3-66for additional
information.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.

The RKE transmitter with the remote start button,
provides an increased range of operation. However, the
range may be less while the vehicle is running. As a
result, you may need to be closer to your vehicle to turn
it off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-4for additional
information.
/(Remote Start):This button will be on the RKE
transmitter if you have remote start.
To start the vehicle:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button, then
immediately press and hold the transmitter’s remote
start button until the turn signal lights ash. If you
cannot see the vehicle’s lights, press and hold the
remote start button for at least four seconds. The
vehicle’s doors will lock. Pressing the remote start
button again, after the vehicle has started, will shut
the vehicle off.
When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.3. If it is the rst remote start since the vehicle has
been driven, repeat these steps while the engine

Or, you can extend the engine run time by another
10 minutes within the rst 10 minute remote start time
frame, and before the engine stops.
2-8

For example, if the lock button and then the remote
start buttons are pressed again after the vehicle
has been running for ve minutes, 10 minutes are
added, allowing the engine to run for 15 minutes.
The additional 10 minutes are considered a second
remote start.
Once two remote starts, or a single remote start with
one time extension has been done, the vehicle must be
started with the key.
After the key is removed from the ignition, the vehicle
can be started using the remote start feature again.
The vehicle cannot be started using the remote
start feature if the key is in the ignition, the hood is not
closed, or if there is an emission control system
malfunction.
Also, the engine will turn off during a remote start if the
coolant temperature gets too high or if the oil pressure
gets low.Vehicles that have the remote vehicle start feature are
shipped from the factory with the remote vehicle
start system enabled. The system may be enabled or
disabled through the DIC if your vehicle has DIC
buttons. See “REMOTE START” underDIC Vehicle
Customization (With DIC Buttons) on page 3-75
for additional information. If your vehicle does not have
DIC buttons, see your dealer/retailer to enable or
disable the remote start system.
Remote Start Ready

Liftgate
{CAUTION:
It can be dangerous to drive with the liftgate
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death.
If you must drive with the liftgate open, or if
electrical wiring or other cable connections
must pass through the seal between the body
and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed with the
recirculation mode off. That will force
outside air into your vehicle. See Climate
Control System in the index.
If you have air outlets on or under the
instrument panel, open them all the way.
If your vehicle has a power liftgate, disable
