The vehicle's doors can be locked and unlocked, and the trunk can be opened from approximately 3 feet (1 m) up to 60 feet (18 m) away with the remote keyless entry transmitter.

If your vehicle has the remote vehicle start feature, you can also start the vehicle's engine with the remote keyless entry transmitter.

Remote Keyless Entry with Remote Start

Remote Keyless Entry without Remote Start

The following functions may be available with your vehicle's remote keyless entry system:

(Remote Vehicle Start): If your vehicle has this feature, the engine may be started from outside the vehicle using the remote keyless entry transmitter. See "Remote Vehicle Start" later in this section for more detailed information.

[block ] (Lock): Press the lock button to lock all the doors. If enabled through the Driver Information Center (DIC), the parking lamps may flash once and the horn may chirp once to indicate locking has occurred. See "REMOTE LOCKS FEEDBACK" under DIC Controls and Displays for programming information. Pressing the lock button will arm the content theft-deterrent system. See Content Theft-Deterrent for more information.

(Unlock): Press the unlock button one time to unlock the driver's door. Press the unlock button again within five seconds to unlock the other doors. 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 may flash once and the horn may chirp once to indicate unlocking has occurred. See "REMOTE LOCKS FEEDBACK" under DIC Controls and Displays . Pressing the unlock button on the remote keyless entry transmitter will disarm the content theft-deterrent system. See Content Theft-Deterrent for more details.

(Trunk Release): Press and hold this button for approximately one second to release the trunk lid. The transaxle must be in PARK (P) for this feature to operate.

(Panic Alarm): Press this button to activate the alarm. The ignition must be in OFF for the remote alarm to work. When the remote alarm button is pressed the headlamps will flash and the horn will sound repeatedly for two minutes. The alarm will turn off when the ignition is moved to RUN or the remote alarm button is pressed again.

Matching Transmitter(s) to Your Vehicle

Each remote keyless entry 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 with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter cannot unlock your vehicle. The vehicle can have a maximum of four transmitters matched to it.

Battery Replacement

Under normal use, the battery in the remote keyless entry transmitter should last about four years.

If the battery is weak the transmitter will not work within its normal range. It is probably time to change the battery if you have to be very close to the vehicle before the transmitter works.

The KEY FOB BATTERY LOW message, in the vehicle's DIC, will display, if the remote keyless entry transmitter battery is low.

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 remote keyless entry transmitter, do the following:

1. Insert a flat object with a thin edge into the notch, located below the panic alarm button, and separate the bottom half from the top half of the transmitter.
2. Remove the old battery and replace it with the new one. Make sure the positive side (+) of the battery faces up. Use one three-volt, CR2032 battery, or equivalent type.
3. Put the two halves back together. Make sure the cover is on tight so water will not get inside the transmitter.
4. Test the operation of the transmitter with the vehicle.

Remote Vehicle Start

Your vehicle may have a remote start 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 and rear window defogger. When the remote start system is active, the climate control system will heat or cool the inside of the vehicle based on the outside temperature. The rear window defogger will be turned on by the climate control system when it is heating the inside of the vehicle. Normal operation of the system will return after the key is turned to RUN.

Laws in some communities may restrict the use of remote starters. For example, some laws may require a person using 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 remote start feature provides two separate starts per ignition cycle, each with 10 minutes of engine running time.

The remote start system needs to be reset after your vehicle's engine is started two times using the transmitter's remote start button. The remote start system is reset by inserting the vehicle's key into the ignition switch and turning to RUN. See Ignition Positions for information regarding the ignition positions on your vehicle.

Your remote keyless entry transmitter with the remote start button provides an increased range of operation. You can start your vehicle from approximately 492 feet (150 m) away. However, the range may be less while the vehicle is running, and 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): If your vehicle has the remote vehicle start feature, the keyless entry transmitter will have a button with this symbol on it.

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 for 4 seconds or until the vehicle's turn signal lamps flash. The vehicle's doors will be locked.
3. When the vehicle starts, the parking lamps will turn on and remain on while the engine is running, and the DIC will display REMOTE START ACTIVE PRESS HAZARD SWITCH TO CANCEL.

The engine will shut off automatically after 10 minutes, unless a time extension has been done or the vehicle's key is inserted into the ignition switch and turned to RUN.

If you enter the vehicle after a remote start, and the engine is still running, insert the key into the ignition switch and turn to RUN to drive the vehicle.

4. To manually shut off a remote start, do any of the following. The parking lamps will turn off.

•	Aim the remote keyless entry transmitter at the vehicle, and press the remote start button.

•	Turn on the hazard warning flashers.

•	Turn the ignition switch to RUN and then to OFF.

Your vehicle's engine can be started two times using the transmitter's remote start feature. If only one remote start procedure has been done, since last driving the vehicle, or resetting the remote start system, the engine may be started again remotely by following the remote start procedure a second time.

If the remote start procedure is used again before the first 10 minute time frame has ended, the first 10 minutes will immediately expire and the second 10 minute time frame will start.

The remote vehicle start feature will not operate if any of the following occur:

If a remote start is attempted and is unsuccessful, the Driver Information Center (DIC) will display REMOTE START DISABLED.

Vehicles that have the remote vehicle start feature are shipped from the factory with the remote start system enabled. The system may be enabled/disabled through the DIC. See "REMOTE START" under DIC Controls and Displays for additional information.

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 the keyless entry transmitter has a plus (+) symbol on the back cover, your vehicle has the remote start ready feature. You can lock or unlock your vehicle from approximately 492 feet (150 m) away.

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