Keyless Access Operation
Some vehicles have the keyless access system that lets you lock and unlock the doors and access the liftgate without removing the remote transmitter from your pocket, purse, briefcase, etc. The keyless entry transmitter must be within 1m (3 ft) of the door being opened.
If the vehicle has this feature, there will be a body colored touch pad on the outside front door handles.
