Section 2 Features and Controls
2-1

At times you may notice a decrease in operating range.
This is normal for any RKE system. If the transmitter
does not work or if you have to stand closer to
your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” later in this
section.
If you are still having trouble, see your dealer/retailer
or a qualied technician for service.
Remote Keyless Entry (RKE)
System Operation
The Remote Keyless Entry (RKE) transmitter functions
will work up to 195 feet (60 m) away. However, the
operating range may be less while the vehicle is running,
therefore, you may need to be closer to your vehicle
to turn it off than you were to start it.
There are other conditions which can affect the
performance of the transmitter. SeeRemote Keyless
Entry (RKE) System on page 2-4.
/(Remote Vehicle
Start):Press
/to start
the engine from outside the
vehicle using the RKE
transmitter. SeeRemote
Vehicle Start on page 2-8
for additional information.
2-5

Remote Vehicle Start
The remote start 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.
During a remote start, the climate control system will
default to a heating mode during colder outside
temperatures and a cooling mode during warmer outside
temperatures.
During a remote start, the rear window defogger and
heated mirrors, if equipped, will turn on during colder
outside temperatures and will shut off when the
key is turned to ON/RUN.
During a remote start, the heated seats will turn on
during colder outside temperatures and will shut
off when the key is turned to ON/RUN. SeeHeated
Seats on page 1-4for 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.
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.
2-8

/(Remote Start):Press and release the lock button
and then press and hold the remote start button to
start the vehicle.
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,
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 turn off the ignition.
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
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 ON/RUN to drive the vehicle.If the vehicle is left running it will automatically
shut off after 10 minutes unless a time extension
has been done.
To manually shut off a remote start:
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.
2-9

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.
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 3-63for additional information. If your vehicle
does not have DIC buttons, see your dealer/retailer to
enable or disable the remote vehicle start system.Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle
will not open it. You increase the chance
of being thrown out of the vehicle in a
crash if the doors are not locked. So, wear
safety belts properly and lock the doors
whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
CAUTION: (Continued)

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system.
With this system, the
security light in the
instrument panel cluster
will ash as you open
the door if your ignition
is off.
This light reminds you to activate the theft-deterrent
system.To activate the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote Keyless Entry (RKE)
transmitter. The security light will illuminate to
inform the driver the system is arming. If a door is
open when the doors are locked, the security
light will ash.
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 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.
If a locked door is opened without the RKE transmitter,
the alarm will go off. The headlamps and parking
lamps will ash and the horn will sound for 30 seconds,
then will turn off to save the battery power.
