OnStar Security 0265.
Programming Transmitters to the Vehicle
Only RKE transmitters programmed to the
vehicle will work. If a transmitter is lost or
stolen, a replacement can be purchased and
programmed through your dealer. When the
replacement transmitter is programmed to
the vehicle, all remaining transmitters must
also be programmed. Any lost or stolen
transmitters no longer work once the new
transmitter is programmed. Each vehicle can
have up to four transmitters programmed
to it.
Battery Replacement
{Warning
Never allow children to play with the RKE
transmitter. The transmitter contains a
small battery, which can be a choking
hazard. If swallowed, internal burns can
occur, resulting in severe injury or death.
Seek medical attention immediately if a
battery is swallowed.
{Warning
To avoid personal injury, do not touch
metal surfaces on the RKE transmitter
when it has been exposed to extreme
heat. These surfaces can be hot to the
touch at temperatures above 59 °C
(138 °F).
Caution
When replacing the battery, do not touch
any of the circuitry on the transmitter.
Static from your body could damage the
transmitter.
Caution
Always replace the battery with the
correct type. Replacing the battery with
an incorrect type could potentially create
a risk of battery explosion. Dispose of
used batteries according to instructions
and local laws. Do not attempt to burn,
crush, or cut the used battery, and avoid
exposing the battery to environments
with extremely low air pressures or high
temperatures.
Caution
If the RKE transmitter is not reassembled
properly, liquids could enter the housing
and damage the circuitry, resulting in an
RKE transmitter malfunction and/or
failure. To prevent damage, always follow
the steps for RKE transmitter reassembly
in this manual to ensure the transmitter
is sealed properly whenever the RKE
transmitter is opened.
Replace the battery if the DIC displays
REPLACE BATTERY IN REMOTE KEY.

Rear Doors
{Warning
Unlocked doors can be dangerous.
.Passengers, especially children, can
easily open the doors and fall out of a
moving vehicle. The doors can be
unlocked and opened while the vehicle
is moving. The chance of being thrown
out of the vehicle in a crash is
increased if the doors are not locked.
So, all passengers should wear seat
belts properly and the doors should be
locked whenever the vehicle is driven.
.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 the vehicle whenever
leaving it.
.Outsiders can easily enter through an
unlocked door when you slow down
or stop the vehicle. Locking the doors
can help prevent this from happening.To open the rear doors from the outside,
pull the handle toward you to open the
passenger side rear door first.
To open the driver side rear door, pull the
latch release at the inside edge of the door.
To close the rear doors, close the driver side
rear door first. Then close the passenger side
rear door. Check to make sure both doors
are completely closed.

passenger door, side door, rear door, or the
hood is opened without first disarming the
system. When the alarm is activated, the
turn signals flash and the horn sounds for
about 30 seconds. The alarm system will
then re-arm to monitor for the next
unauthorized event.

should but the lamps flash, check to see
if the horn works. The horn fuse may be
blown. To replace the fuse, see Fuses and
Circuit Breakers 0198.
Immobilizer
See Radio Frequency Statement 0260.
Immobilizer Operation
This vehicle is equipped with the
PASS-Key®III+ (Personalized Automotive
Security System) theft-deterrent system.
PASS-Key III+ is a passive theft deterrent
system.
The system is automatically armed when
the key is removed from the ignition.
You do not have to manually arm or disarm
the system.
The security light will come on if there is a
problem with arming or disarming the
theft-deterrent system.
If the engine does not start and the security
light comes on, the key may have a
damaged transponder. Turn the ignition off
and try again.
If the engine still does not start, and the
key appears to be undamaged, try another
ignition key. If the engine still does not
start with the other key, the vehicle needs
service. If the vehicle does start, the first
key may be faulty. See your dealer or a
locksmith who can service the PASS-Key III+
to have a new key made.
