Remote Keyless Entry (RKE)
System
Your Remote Keyless Entry (RKE) system 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

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.

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
60 feet (18 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. With Remote Start
Shown, Without Remote
Start Similar

Q(Lock):Press the lock button to lock all the doors.
If enabled through the Driver Information Center
(DIC), the parking lamps will ash once to indicate
locking has occurred. If enabled through the DIC, the
horn will chirp when the lock button is pressed
again within ve seconds of the previous press of the
lock button. SeeDIC Vehicle Customization on
page 3-66for additional information. Pressing the lock
button may arm the content theft-deterrent system.
SeeContent Theft-Deterrent on page 2-17.
"(Unlock):Press the unlock button to unlock the
driver’s door. If the button is pressed again within
ve seconds, all remaining doors will unlock. The interior
lamps will come on and stay on for 20 seconds or until
the ignition is turned on. If enabled through the DIC, the
parking lamps will ash once to indicate unlocking has
occurred. SeeDIC Vehicle Customization on page 3-66.
Pressing the unlock button on the RKE transmitter will
disarm the content theft-deterrent system. SeeContent
Theft-Deterrent on page 2-17.
V(Remote Trunk Release):Press and hold this
button for about one second to release the trunk lid.
The transmission must be in PARK (P) for this feature
to operate.
L(Vehicle Locator/Panic Alarm):Press and release
this button to locate your vehicle. The turn signal
lamps will ash and the horn will sound three times.
Press and hold this button for more than two seconds to
activate the panic alarm. The turn signal lamps will ash
and the horn will sound repeatedly for 30 seconds. The
alarm will turn off when the ignition is moved to ON/RUN
or the alarm button is pressed again. The ignition must be
in LOCK/OFF for the panic alarm to work.
Matching Transmitter(s) to Your
Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a transmitter
is lost or stolen, a replacement can be purchased
through your dealer/retailer. Remember to bring any
additional transmitters so they can also be re-coded to
match the new transmitter. Once your dealer/retailer
has coded the new transmitter, the lost transmitter will
not unlock your vehicle. The vehicle can have a
maximum of eight transmitters matched to it. See
“Remote Key” underDIC Operation and Displays on
page 3-49.
2-6

Battery Replacement
Under normal use, the battery in your RKE transmitter
should last about four years.
The battery is weak if the transmitter will not work at the
normal range in any location. If you have to get close
to your vehicle before the transmitter works, it is
probably time to change the battery.
The REPLACE BATTERY IN REMOTE KEY message
in the vehicle’s DIC will display if the RKE transmitter
battery is low. See “REPLACE BATTERY IN REMOTE
KEY” underDIC Warnings and Messages on
page 3-56for additional information.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.To replace the battery in the RKE transmitter:
1. Insert a at object with a thin edge into the notch,
located below the trunk release button, and
separate the bottom half from the top half of the
transmitter.
2. Remove the old battery, but do not use a metal
object to do this.
3. Slide the new battery into the transmitter with the
positive side of the battery facing down. Use a
type CR2032 battery, or equivalent type. Make sure
the cover is on tightly, so water will not get in.
4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
2-7

Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside
the vehicle. It may also start the vehicle’s heating or air
conditioning systems, rear window defogger, and
heated seats. SeeHeated Seats on page 1-4and
Heated and Cooled Seats on page 1-5for additional
information. When the remote start system is active, the
climate control system will heat or cool the inside of
the vehicle at the setting the vehicle was set to when the
vehicle was last turned off. The rear window defogger
will be turned on by the climate control system when it is
cold outside. If the vehicle has heated seats, they
may also turn on when it is cold outside. Cooled seats
are not activated during a remote start. Normal
operation of the system will return after the key is
turned to the ON/RUN position.
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 remote start, the RKE transmitter
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.
/(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 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 will lock.
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.
