Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked,
and the trunk can be opened 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 the
vehicle’s engine with the RKE transmitter.The following functions may be available with your
vehicle’s RKE system:/(Remote Vehicle Start):If your vehicle has
this feature, the engine may be started from
outside the vehicle using the RKE transmitter.
See “Remote Vehicle Start” at the end of
this section for more detailed information.
Q(Lock):Press the lock button to lock all the
doors. If enabled through the Driver Information
Center (DIC), the parking lamps may ash once to
indicate locking has occurred, or the horn may
chirp when the lock button is pressed again within
ve seconds from the previous press of the
lock button. See “FOB LOCK FEEDBACK” under
DIC Vehicle Personalization on page 229for
additional information. If the vehicle has the
content theft-deterrent system, pressing the lock
button may also arm it. SeeContent
Theft-Deterrent on page 104.

"(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 can
be programmed to come on for a set amount of
time when the vehicle is unlocked using the
RKE transmitter. See “EXT (Exterior) LIGHT
DELAY” underDIC Vehicle Personalization on
page 229. If the vehicle has the content
theft-deterrent system, pressing the unlock button
on the RKE transmitter may disarm it. See
Content Theft-Deterrent on page 104.
V(Remote Trunk Release):Press and hold
this button for about one second to release
the trunk lid. The transaxle must be in PARK (P)
for this feature to operate.
L(Panic Alarm):Press this button to activate the
alarm. The ignition must be in OFF or
ACCESSORY for the alarm to work. When the
alarm button is pressed, the headlamps will ash
and the horn will sound repeatedly for two minutes.
The alarm will turn off when the ignition is moved to
RUN or the alarm button is pressed again.
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 GM dealer. Remember
to bring any additional transmitters so they
can also be re-coded to match the new transmitter.
Once your dealer has coded the new transmitter,
the lost transmitter will not unlock your vehicle.
The vehicle can have a maximum of four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in the 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 KEY FOB BATT LOW message in the
vehicle’s DIC will display if the RKE transmitter
battery is low.

Sun Visors
To block out glare, swing down the sun visors.
They can be detached from the center retainer and
slid along the rod to cover different areas of the
front window and turned to cover the side
windows.
Visor Vanity Mirror
Swing down the sun visors and lift the cover to
expose the vanity mirror. Do not drive with
the cover lifted due to possible glare impeding
other drivers behind or to the side of the vehicle.
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 may have a content theft-deterrent
alarm system.
A red light located on
top of the instrument
panel, toward the center
of the vehicle and
near the windshield, will
ash slowly when the
system is armed.
The theft-deterrent alarm system needs to be
activated through the Driver Information Center
(DIC). See “CONTENT THEFT” under
“Customization Menu Items” inDIC Vehicle
Personalization on page 229. While armed, the
doors will not unlock with the power door lock
switch. The remote alarm will sound if someone
tampers with the trunk or enters the vehicle without
using the remote keyless entry transmitter or key to
unlock the doors. The horn will sound and the
headlamps will ash for up to two minutes. The
system will also cut off the fuel supply, preventing
the vehicle from being driven.

TPMS Sensor Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires, the
identication codes need to be matched to the
new tire/wheel position. The sensors are matched,
to the tire/wheel positions, in the following order:
driver side front tire, passenger side front tire,
passenger side rear tire, and driver side rear tire
using a TPMS diagnostic tool. See your dealer
for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall.
You have two minutes to match each tire and
wheel position. If it takes longer than two minutes
to match any tire and wheel position, the
matching process stops and you need to
start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Press the Remote Keyless Entry (RKE)
transmitter’s LOCK and UNLOCK buttons
at the same time for approximately
ve seconds. The horn sounds twice to
signal the receiver is in relearn mode and the
TPMS sensor matching process can begin.
4. Start with the driver side front tire.
5. Remove the valve cap from the tire’s valve
stem. Activate the TPMS sensor by increasing
or decreasing the tire’s air pressure for
10 seconds, or until a horn chirp sounds.
The horn chirp, which may take up to
30 seconds to sound, conrms that the sensor
identication code has been matched to the
tire/wheel position. To decrease the tire’s
air-pressure use the pointed end of the valve
cap, a pencil-style air pressure gage, or a key.

6. Proceed to the passenger side front tire,
and repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire,
and repeat the procedure in Step 5.
8. Proceed to the driver side rear tire, and
repeat the procedure in Step 5.
9. After hearing the conrming horn chirp for the
driver side rear tire, the horn chirps two more
times to signal the tire learning process
has ended. Turn the ignition switch to OFF.
10. Set all four tires to the recommended air
pressure level as indicated on the tire and
loading information label.
11. Put the valve caps back on the valve stems.Federal Communications Commission
