system, it operates on a radio frequency subject
to Federal Communications Commission (FCC) Rules
and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.At times you may notice a decrease in range. This is
normal for any RKE system. If the transmitter does not
work or if you have to stand closer to your vehicle

Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked, and
the trunk can be unlatched from about 3 feet (1 m)
up to 65 feet (20 m) away with the Remote Keyless
Entry (RKE) transmitter.
If your vehicle has the remote start feature you can also
start your vehicle with the RKE transmitter. Your RKE
transmitter, with the remote start button, provides
an increased range of 195 feet (60 m) away. 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 2-4.The following functions may be available if your vehicle
has the RKE system:
/(Remote Vehicle Start):If your vehicle has this
feature, it may be started from outside the vehicle using
the RKE transmitter. SeeRemote Vehicle Start on
page 2-8for additional information. RKE with Remote Start
RKE without Remote
Start
2-5

Remote Vehicle Start
Your vehicle may have a remote starting feature that
allows you to start the engine from outside the vehicle.
It may also start the vehicle’s heating or air conditioning
systems and rear window defogger. When the remote
start system is active and the vehicle has an automatic
climate control system, it will automatically regulate the
inside temperature. Normal operation of these systems
will return after the ignition key is turned to ON/RUN.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using 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.
Your Remote Keyless Entry (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 2-4.
/(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,
then immediately press and hold the transmitter’s
remote start button for about four seconds or
until the vehicle’s turn signal lamps ash.
The doors will lock.
When the vehicle starts, the parking lamps turn on
and remain on while the engine is running.
The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time, or one start with a time extension. The rst
start must expire or be canceled to get two separate
10 minute starts.
If it is the rst remote start since the vehicle has been
driven, repeat the previous steps, while the engine is
still running, to extend the engine running time by
10 minutes from the time you repeat the steps for
remote starting. The remote start running time can be
extended one time and only after the rst remote start.
After entering the vehicle during a remote start,
insert and turn the key to ON/RUN to drive the vehicle.

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.
Outsiders can easily enter through an
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.
From the outside, use your key in the driver’s door or
use the remote keyless entry transmitter. From the
inside, use the manual or power door locks.
To unlock the driver’s side door from the outside with
the key, insert the key and turn it counterclockwise.
To lock the driver’s side door from the outside with your
key, insert the key and turn it clockwise.
To lock the door from
the inside, push the
manual lock knob down.
To unlock the door,
pull the knob up.

Power Door Locks
A power door lock switch
is located on both front
doors next to the door
handle.
Press the top of the switch to unlock all doors, or press
the bottom of the switch to lock all doors.
If your vehicle has the optional content theft-deterrent
system and it is armed, the power door lock switches will
be disabled. You must use your remote keyless entry
transmitter or your key to unlock the doors when
the system is armed. SeeContent Theft-Deterrent on
page 2-18.
Delayed Locking
This feature allows the driver to delay the actual locking
of the doors. When the driver’s power door lock
switch is pressed with the key removed from the ignition,
and the driver’s door open, a chime will sound three
times to signal that the delayed locking system is active.
When all doors have been closed, the doors will lock
automatically after several seconds. If any door is
opened before this, the timer will reset itself once all the
doors have been closed again.
Pressing the driver’s or passenger’s power door lock
switch again or the remote keyless entry transmitter
button will override this feature.
Personal Choice Programming
The delayed locking feature can be turned on or off,
using the Driver Information Center (DIC) to program
this feature. See “DELAY DOOR LOCK” underDIC
Vehicle Customization on page 3-60.

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, if the vehicle has one, the power
door lock switch, or by lifting the rear door
manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert the key into the security lock slot and turn it

Lockout Protection
This feature helps prevent you from locking the doors
while your key is in the ignition. Always remember
to take your key with you when exiting your vehicle.
If the lock switch is pressed on the door that is open and
the key is in the ignition, all of the doors will lock and
then the driver’s door will unlock. A chime will sound
continuously until all doors are closed.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
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 trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
