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. SeeHeated
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.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
information.
/(Remote Start):This button will be on the RKE
transmitter if you have remote start.
To start the vehicle using the remote start feature:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button.
The vehicle’s doors will lock. 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
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.
2-8

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.
After entering the vehicle during a remote start, insert
and turn the key to RUN to drive the vehicle.
To manually shut off a remote start, do any of the
following:
Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The vehicle can be remote started two separate times
between driving sequences. The engine will run for
10 minutes after each remote start.
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.
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” under
DIC Vehicle Customization (With DIC Buttons) on
page 3-67for 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.

no one in the way of the liftgate as it is
opening and closing.
Notice:If you open the liftgate without checking for
overhead obstructions such as a garage door,

extreme temperatures, or under low battery conditions. If
this occurs, the liftgate can still be operated manually.
If you shift the transmission out of PARK (P) while
the power function is in progress, the liftgate power
function will continue to completion. If you shift the
transmission out of PARK (P) and accelerate before the
power liftgate latches closed, the liftgate may reverse
to the open position. Cargo could fall out of the vehicle.
Always make sure the power liftgate is closed and
latched before you drive away.

Content Theft-Deterrent
Your vehicle may have a content theft-deterrent alarm
system.
This is the security light.
To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote Keyless Entry (RKE)
transmitter or the power door lock switch. The
security light will come on to inform the driver the
system is arming. If a door is open when the doors
are locked, the security light will ash.
If the delayed locking feature is turned on, the
theft-deterrent system will not start the arming
process until the last door is closed and the delay
timer has expired. SeeDelayed Locking on
page 2-11.3. Close all doors. The security light should go off
after about 30 seconds. The alarm is not armed
until the security light goes off.
If a locked door is opened without using the RKE
transmitter, a ten second pre-alarm will occur. The horn
will chirp and the lights will ash. If the key is not
placed in the ignition and turned to START or the door
is not unlocked by pressing the unlock button on the
RKE transmitter during the ten second pre-alarm,
the alarm will go off. Your vehicle’s headlamps will ash
and the horn will sound for about two minutes, then
will turn off to save the battery power.
The theft-deterrent system will not activate if the doors
are locked with the vehicle’s key or the manual door lock.
It activates only if you use the power door lock switch with
the door open or the RKE transmitter. You should also
remember that you can start your vehicle with the correct
ignition key if the alarm has been set off.
To avoid setting off the alarm by accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door key after the doors are closed.
Always unlock the doors with the RKE transmitter.
Unlocking a door any other way will set off the
alarm if it is armed.
