Keyless Unlocking
With the keyless access transmitter within 1m (3 ft), approach the front door and pull the handle to unlock and open the door. On some models there is a touch sensor on the door handle. If the transmitter is recognized, the door will unlock and open.
To access the rear doors first, pull the rear door handle once to unlock all doors and a second time to open the door.
Entering any door other than the driver door will cause all of the doors to unlock. This is not customizable.
To customize which doors unlock when the driver door is opened, see “Keyless Unlock” under Vehicle Personalization.
