The vehicle's doors can be locked and unlocked from about 3 feet (1 m) up to 65 feet (20 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. The RKE transmitter, with the remote start button, provides an increased operating range of 195 feet (60 m) away. However, the operating 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 start it.

There are other conditions which can affect the performance of the transmitter. See Remote Keyless Entry (RKE) System .

The alarm will turn off when the ignition is moved to RUN or the alarm button is pressed again. The ignition must be in 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 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 eight transmitters matched to it. See "Relearn Remote Key" under DIC Operation and Displays for instructions on how to match RKE transmitters to your vehicle.

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 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" under DIC Warnings and Messages for additional information.

Notice: When replacing the battery, do not touch any of the circuitry on the transmitter. Static from your body could damage the transmitter.

To replace the battery in the RKE transmitter do the following:

1. Insert a flat object with a thin edge into the notch on the side of the transmitter and separate the bottom half from the top half.
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.

Remote Vehicle Start

Your vehicle may have a remote starting feature. This feature allows you to start the engine from outside of the vehicle. It may also start up the vehicle's heating or air conditioning systems and rear window defogger. Normal operation of the system will return after the key is turned to the RUN position.

During a remote start, if your vehicle has an automatic climate control system, the climate control system will default to a heating mode during colder outside temperatures and a cooling mode during warmer outside temperatures. If your vehicle does not have an automatic climate control system, during remote start, the climate control system will turn on at the setting the vehicle was set to when the vehicle was last turned off.

During a remote start, if your vehicle has an automatic climate control system and heated seats, the heated seats will turn on during colder outside temperatures and will shut off when the key is turned to RUN. If your vehicle does not have an automatic climate control system, during remote start, you will need to manually turn the heated seats on and off. See Heated Seats for additional information.

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.

The RKE transmitter with the remote start button, 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, see Remote Keyless Entry (RKE) System for additional information.

(Remote Start): Press and release the lock button and then press and hold the remote start button to start the vehicle.

To start the vehicle using the remote start feature, do the following:

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 flash. If you cannot see the vehicle's lights, press and hold the remote start button for at least four seconds. The vehicle's doors will lock. Pressing the remote start button again after the vehicle has started will turn off the ignition.

When the vehicle starts, the parking lamps will turn on and remain on while the vehicle is running.

3. If it is the first 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, insert and turn the key to RUN to drive the vehicle.

If the vehicle is left running it will automatically shut off after 10 minutes unless a time extension has been done.

To manually shut off a remote start, do any of the following:

The vehicle can be remote started two separate times between driving sequences. The engine will run for 10 minutes after each remote start.

Or, you can extend the engine run time by another 10 minutes within the first 10 minute remote start time frame, and before the engine stops.

For example, if the lock button and then the remote start buttons are pressed again after the vehicle has been running for five minutes, 10 minutes are added, allowing the engine to run for 15 minutes.

The additional ten minutes are considered a second remote vehicle start.

Once two remote starts, or a single remote start with one time extension has been done, the vehicle must be started with the key.

After the key is removed from the ignition, the vehicle can be remote started again.

The vehicle cannot be remote started if the key is in the ignition, the hood is not closed, or if there is an emission control system malfunction.

Also, the engine will turn off during a remote vehicle start if the coolant temperature gets too high or if the oil pressure gets low.

Vehicles that have the remote vehicle start feature are shipped from the factory with the remote vehicle start system enabled. The system may be enabled or disabled through the DIC. See "REMOTE START" under DIC Vehicle Customization for additional information. If your vehicle does not have DIC buttons, see your dealer to enable or disable the remote vehicle start system."

Remote Start Ready

If your vehicle does not have the remote vehicle start feature, it may have the remote start ready feature. This feature allows your dealer to add the manufacturer's remote vehicle start feature.

If your vehicle has the remote start ready feature, the RKE transmitter will have an extended range that allows locking or unlocking of the vehicle from approximately 197 feet (60 m) away.

See your dealer if you would like to add the manufacturer's remote vehicle start feature to your vehicle.
