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 down.

4. Put the transmitter back together tightly.
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.
During a remote start, if your 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 your 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 Seats on page 1-5for 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.
2-7

Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
If your 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, seeRemote Keyless
Entry (RKE) System on page 2-4for additional

lights, press and hold the remote start button for
two to four seconds. Pressing the remote start
button again after the vehicle has started will
turn the engine off.
When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.If the vehicle is left running it will automatically shut
off after 10 minutes unless a time extension has
been done.
3. If it is the rst remote start since the vehicle has
been driven, repeat these steps, while the engine
is still running, to extend the engine running time
by 10 minutes. Remote start can be extended
one time.

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 ten minutes are considered a second
remote vehicle 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 remote started again.
The vehicle cannot be remote started if the key is
in the ignition, the hood is not closed, or if there is
an emission control system malfunction and the
check engine light comes on.
Also, the engine will turn off during a remote vehicle
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. See “REMOTE START” underDIC
Vehicle Customization (With DIC Buttons) on page 3-76
for additional information. If your vehicle does not have
DIC buttons, see your dealer/retailer to enable or disable
the remote vehicle start system.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature.
This feature allows your dealer/retailer to add the
manufacturer’s remote vehicle start feature.
See your dealer/retailer if you would like to add the
manufacturer’s remote vehicle start feature to your
vehicle.

unlocked door when you slow down or
stop your vehicle. Locking your doors
can help prevent this from happening.There are several ways to lock and unlock your vehicle.
