The vehicle's doors can be locked and unlocked, and the trunk can be unlatched from about 3 feet (1 m) up to 65 feet (20 m) away with the remote keyless entry transmitter.

If your vehicle has the remote start feature you can also start your vehicle with the remote keyless entry transmitter. Your remote keyless entry 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. See Remote Keyless Entry (RKE) System .

Remote Keyless Entry with Remote Start

Remote Keyless Entry without Remote Start

The following functions may be available if your vehicle has the remote keyless entry system:

(Remote Vehicle Start): If your vehicle has this feature, it may be started from outside the vehicle using the remote keyless entry transmitter. See "Remote Vehicle Start" following 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 will flash once to indicate locking has occurred. If enabled through the DIC, the horn will chirp when the lock button is pressed again within five seconds of the previous press of the lock button. See DIC Vehicle Customization for additional information. Pressing the lock button may arm the content theft-deterrent system. See Content Theft-Deterrent .

(Unlock): Press the unlock button to unlock the driver's door. If the button is pressed again within five 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 will flash once to indicate unlocking has occurred. See DIC Vehicle Customization . Pressing the unlock button on the remote keyless entry transmitter will disarm the content theft-deterrent system. See Content Theft-Deterrent .

(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.

(Vehicle Locator/Panic Alarm): Press and release this button to locate your vehicle. The turn signal lamps will flash and the horn will sound three times. Press and hold this button for more than two seconds to activate the panic alarm. The turn signal lamps will flash and the horn will sound repeatedly for 30 seconds. The alarm will turn off when the ignition is turned 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 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 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 Remote Key under DIC Operation and Displays .

Battery Replacement

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

You can tell 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 remote keyless entry 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 remote keyless entry transmitter do the following:

1. Use a flat 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.

Remote Vehicle Start

Your vehicle may have a remote starting feature. This feature allows you to start the engine from outside of the vehicle.

If your vehicle has an outside temperature display, during remote start this feature allows the climate control system to default to a heating mode during colder outside temperatures and a cooling mode during warmer outside temperatures. If your vehicle does not have an outside temperature display, 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.

Laws in some communities may restrict the use of remote starters. For example, requiring 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.

Your remote keyless entry 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 this button to use the remote start feature.

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 or if the vehicle's lights are not visible. 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 remote vehicle start feature provides two separate starts, each with 10 minutes of engine running, or it provides one start with 10 minutes of engine running that may be extended with 10 more minutes. If you press and release the transmitter lock button and then press and hold the remote start button, on the remote keyless entry transmitter, again before the first 10 minutes of engine running time has expired, 10 minutes are added to the remaining minutes. For example, if the lock button and then the remote start buttons are pressed again after five minutes of the engine run time, 10 minutes are added and you now have 15 minutes of engine running. The added ten minutes are considered a second remote vehicle start. Once two remote starts or a single start with a time extension have been provided, the vehicle must be started normally with the ignition key to get more remote vehicle starts.

The remote vehicle start feature will not operate 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 equipped with 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.

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, your remote keyless entry transmitter will have extended range that will allow you to lock or unlock your vehicle from about 195 feet (60 m) away.

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