Object Number: 1252192  Size: A3

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

(Remote Start): If your vehicle has this feature, it may be started remotely by pressing the lock button, then immediately following, pressing the remote start button and holding it until the turn signal lamps flash, or for four seconds if the lights are not visible. Pressing the remote start button again after the vehicle has started will turn off the ignition. See "Remote Vehicle Start" following for more information.

[block ] (Lock):  Press the lock button to lock all the doors. The interior lamps will turn off after all of the doors are closed. 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 also chirp to indicate locking has occurred.

(Unlock): Press the unlock button to unlock the driver's door. If the button is pressed again within five seconds, all remaining doors, and liftgate 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 twice to indicate unlocking has occurred.

(Remote Trunk/Liftgate Release): The trunk or liftgate will unlatch when this button on the transmitter is pressed and held for approximately one second. You can open the sedan trunk with the transmitter when the vehicle is stationary. You can open the liftgate on the MAXX only when the vehicle is in PARK (P).

(Vehicle Locator/Panic Alarm): Press this button to locate your vehicle. The horn will chirp three times and the headlamps and parking lamps will flash three times. Press and hold the button for three seconds to sound the panic alarm. The horn will chirp and the headlamps and parking lamps will flash for 30 seconds. Press the button again to cancel the panic alarm.

Programmable Horn Chirp

Through the DIC, you may choose whether or not to have a horn chirp when you use the remote keyless entry transmitter to lock or unlock the doors.

See DIC Operation and Displays for more information.

Radio Preset Association with the Remote Keyless Entry

If your vehicle has remote keyless entry, when programming the radio presets, 1 through 6, these settings will correspond with the remote. Two drivers can store different preset stations. When unlock is pressed on the remote, the preset stations that the driver stored, will be recalled. The settings for the preset stations are stored when the ignition is turned off. See "Setting Preset Stations" for the radio that your vehicle has.

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 dealer. Remember to bring any remaining 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 will not unlock your vehicle. Each vehicle can have a maximum of four transmitters matched to it.

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 won't work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it's probably time to change the battery.

The Key FOB Batt 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. Use a flat object like a coin to separate the bottom half from the top half of the transmitter.
  2. Remove the battery and replace it with the new one. Make sure the positive side of the battery faces up. Use one three-volt, CR2032, or equivalent, type battery.
  3. Put the two halves back together. Make sure the cover is on tightly, so water won't get in.

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 also starts up the vehicle's heating or air conditioning systems and rear window defogger. When the remote start system is active and the vehicle has an automatic climate control system, it will automatically regulate the inside temperature. Normal operation of the system will return after the key is turned to the on position. A remote start occurs when buttons on the remote keyless entry transmitter are pressed.

Laws in some local communities require that a person using remote start have the vehicle in view when doing so and may prohibit the execution of remote start if not in view of the vehicle. 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, each with 10 minutes of engine running. Or it provides one start with 10 minutes of engine running, which can be extended by 10 more minutes, for 20 minutes of total running time. Once two starts or 20 minutes running time has been provided, the vehicle must be started normally with the ignition key to get more remote starts.

The remote start feature will not operate if the key is in the ignition or the hood is not closed.

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 System Operation" previously in this section.

(Remote Start): Press the lock button and then press 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 the transmitter's lock button, release it and then immediately press and hold the transmitter's remote start button until the vehicle's turn signal lights flash or for at least four seconds. The vehicle's doors will be locked.
  3. When the vehicle starts, the parking lamps will turn on and remain on while the vehicle is running.
  4. If it is your first remote start since last driving, repeat these steps while the engine is still running for a 10 minute time extension.

When you enter the vehicle during a remote start, turn the key to the on position to start the engine and drive.

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:

    • Aim the remote keyless entry transmitter at the vehicle and press the remote start button until the parking lamps turn off.
    • Turn on the hazards warning flashers.
    • Turn the ignition switch on and then off.
