Each Keyless Access System is coded to allow only
transmitters programmed to your vehicle to work.
If a transmitter is lost or stolen, a replacement can be
purchased and programmed through your dealer/retailer.
Your dealer/retailer can reprogram your vehicle so
lost or stolen transmitters no longer work with your
vehicle. Each vehicle can have a maximum of four
transmitters matched to it.To match a new transmitter to your vehicle when
you have a recognized transmitter, do the following.
Two recognized transmitters are required for Canadian
owners.
1. The vehicle must be off.
2. Have the recognized transmitter and the new,
unrecognized transmitter(s) with you.
3. Insert the key into the key lock cylinder located on
the outside of the driver’s door.
4. Turn the key to the unlock position ve times within
ve seconds.
5. The Driver Information Center (DIC) will display
Ready To Learn Electronic Key #X, where X can
be2,3or4.
6. Place the new,
unrecognized
transmitter into the
transmitter pocket with
the transmitter buttons
facing the front of the
vehicle. The transmitter
pocket is inside the
center console storage
area located between
the driver and front
passenger seats.

transmitters when two recognized transmitters are not
available. United States owners are permitted to match
a new transmitter to their vehicle when a recognized
transmitter is not available.The procedure will require three, ten minute cycles to
complete the matching process.
1. The vehicle must be off.
2. Place the new,
unrecognized
transmitter into the
transmitter pocket with

Battery Replacement
Replace the battery if the Replace Battery In Remote
Key message displays in the DIC. See “Replace Battery
In Remote Key” underDIC Warnings and Messages
on page 3-56for additional information.
A weak battery may also cause the DIC to display

any of the circuitry on the transmitter. Static
from your body could damage the transmitter.To replace the battery:
1. Separate the halves of the transmitter with a at,
thin object inserted into the slot on the side or

Remote Vehicle Start
This vehicle may have a remote starting feature that
starts the engine from outside of the vehicle. It may also
start the vehicle’s automatic climate control system.
When the remote start system is active, the climate
control system heats and cools the inside of the vehicle
according to the previous settings of the system
before turning the vehicle off. The windshield defroster
or rear window defogger turn on if it is cold outside.
If the vehicle has heated seats, they also turn on. See
Heated and Ventilated Seats on page 1-6for additional
information. Normal operation of the climate control
system returns after the ignition is turned to ON/RUN.
SeeDual Climate Control System on page 3-24.
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 the vehicle is low
on fuel. The vehicle may run out of fuel.
If this vehicle has the remote start feature, the RKE
transmitter functions 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 2-6orKeyless Access
System on page 2-9for additional information.
/(Remote Start):Press and release the lock button
and then press and hold this button to use the remote
start feature.
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 or
if the vehicle’s lights are not visible, press and hold
the remote start button for at least four seconds.
The vehicle’s doors lock. Pressing the remote start
button again after the vehicle has started turns off
the ignition.
When the vehicle starts, the parking lamps 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, press
the brake pedal and turn the ignition to ON/RUN to drive
the vehicle.
2-16

If the vehicle is left running it automatically shuts off
after 10 minutes unless a time extension has been done.
To manually shut off a remote start:
Aim the 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 remote vehicle start feature provides two separate
starts, each with 10 minutes of engine running, or it
provides one start with 10 minutes of engine running
that may be extended 10 more minutes. If the transmitter
lock button is pressed and released and then the remote
start button is pressed and held again before the rst
10 minutes of engine running time has expired,
10 minutes are added to the remaining minutes.
For example, if the lock button and then the remote
start buttons are pressed again after ve minutes of
the engine run time, 10 minutes are added and you
now have 15 minutes of engine running. The added
ten minutes are considered a second remote vehicle
start.
Once two remote starts or a single start with a time
extension have been used, the vehicle must be started
with the keyless access ignition control knob before
the remote start feature can be used again.The remote start feature does not operate if any of the
following occur:
The ignition is in any position other than LOCK/OFF.
A keyless access transmitter is inside the vehicle.
The hood is open.
There is an emission control system malfunction.
The remote start feature is not enabled.
See “Remote Start” underDIC Vehicle
Customization on page 3-69.
The engine turns off during a remote vehicle start if the
coolant temperature gets too high, or the oil pressure
is too low.
This vehicle was shipped from the factory with the
remote vehicle start system enabled. The system may
be disabled through the Driver Information Center (DIC).
See “Remote Start” underDIC Vehicle Customization
on page 3-69for additional information.
SeeEngine Exhaust on page 2-48for important safety
information when using remote start in a closed garage.

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 inside, use the manual lock levers located
on the door panels near the windows.
Push down on the manual lock lever to lock the door.
To unlock the door, pull up on the lever.
If the windows are down and the doors are locked, do
not reach in to manually unlock the vehicle because you
will set off the alarm.
From the outside, use the key, or press the lock or
unlock button on the Remote Keyless Entry (RKE)
transmitter. SeeRemote Keyless Entry (RKE) System
Operation on page 2-7for more information.
On vehicles with the Remote Keyless Access system,
the door unlocks by pulling the door handle when
you have the transmitter with you. SeeKeyless Access
System Operation on page 2-10for more information.
