    • when you press UNLOCK on your remote keyless entry transmitter again within five seconds, all doors will unlock.

Programmable Modes

Mode 1: Remote All Doors Unlock - When you press UNLOCK on the remote keyless entry transmitter once, all doors will unlock

Mode 2: Remote Driver's Door and All Doors Unlock - When you press UNLOCK on the remote keyless entry transmitter once, the driver's door will unlock. If you press UNLOCK again within five seconds, all doors will unlock.

Before your vehicle was shipped from the factory, it was programmed to Mode 2. The mode to which your vehicle was programmed may have been changed since it left the factory. To determine the mode to which your vehicle is programmed or to program your vehicle to a different mode, do the following:

  1. Follow the instructions for Entering Programming Mode .
  2. Press UNLOCK on the remote keyless entry transmitter.
  3. Count the number of chimes you hear. The number of chimes tells you which mode the vehicle is set for. If you do not wish to change the current mode, you can either exit the programming mode by following the instructions later in this section or program the next feature available on your vehicle.
  4. Press UNLOCK on the remote keyless entry transmitter again to change the current mode.
  5. Repeat Step 4 until you hear the number of chimes that matches the mode you want.

The mode you selected is now set. You can either exit the programming mode by following the instructions later in this section or program the next feature available on your vehicle. See Exiting Programming Mode .
