When the replacement transmitter
is programmed to this vehicle,
all remaining transmitters must also
be reprogrammed. Any lost or stolen
transmitters will no longer work
once the new transmitter is
programmed. The vehicle can have
a maximum of eight transmitters
programmed to it. See your dealer
to program transmitters to the
vehicle.
Battery Replacement
Replace the battery if the REPLACE
BATTERY IN REMOTE KEY
message displays in the DIC. See
REPLACE BATTERY IN REMOTE
KEY under Key and Lock
Messages on page 5 39 for
additional information.
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
flat, thin object, such as a flat
head screwdriver.
Carefully insert the tool
into the notch located
along the parting line of the
transmitter. Do not insert
the tool too far. Stop as
soon as resistance is felt.
Twist the tool until the
transmitter is separated.
2. Remove the old battery. Do not
use a metal object.

Remote Vehicle Start
Your vehicle may have a remote
starting feature. 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 your 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 your
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.
