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

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.

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 may have the optional content
theft-deterrent alarm system.
To activate the theft-deterrent system:
1. Open the door.
2. Lock the door with the power door lock switch or
the Remote Keyless Entry (RKE) transmitter. If
you are using the RKE transmitter, the door does
not need to be open.
3. Close all doors.
Once armed, the alarm will go off if someone tries to
enter the vehicle without using the RKE transmitter or a
key or turns the ignition on with an incorrect key. The
horn will sound and the turn signal lamps will ash
for about two minutes.
When the alarm is armed, the trunk may be opened
with the RKE transmitter. The power door lock switches
are disabled and the doors remain locked. You must
use your RKE transmitter or your key to unlock the doors
when the system is armed.

How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R). The rear display will then
briey illuminate to let you know the system is working.
URPA operates only at speeds less than 5 mph
(8 km/h). If you are above this speed, the red light on
the rear display will ash.
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below trunk level. Objects
must also be within 8 feet (2.5 m) from your rear
bumper. This distance may be less during warmer or
humid weather.
A single beep will sound the rst time an object is
detected between 20 inches (0.5 m) and 8 feet (2.5 m)
away. Beeping will occur for three seconds when
you are closer than 1 foot (0.3 m) from the object.
The following describes what will occur with the URPA
display as you get closer to a detected object:
Description English Metric
amber light 8 ft 2.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights 23 in 0.6 m
amber/amber/red lights
ashing and beep for
three seconds1 ft 0.3 mThe system can be disabled through the Driver
Information Center (DIC). See “Park Assist” underDIC
Operation and Displays on page 3-49for more
information.
When the System Does Not Seem to
Work Properly
The driver disables the system.
The parking brake pedal is depressed.
The ultrasonic sensors are not clean. Keep your
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-98.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your trunk during
your last drive cycle, the red light may illuminate in
the rear display. Once the attached object is
removed, URPA will return to normal operation.
A tow bar is attached to your vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 15 mph (25 km/h), take your vehicle to your
dealer/retailer.
