Remote Keyless Entry
(RKE) System Operation
(Keyless Access)
The Keyless Access System
transmitter will work up to 60 m
(195 ft) away.
The Keyless Access System locks
and unlocks the doors and trunk
without pressing the buttons on
the keyless access transmitter.
The keyless access transmitter
must be within 1 m (3 ft) of the door
or trunk being opened.
Keyless Unlocking
With the keyless access transmitter
within 1 m (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.
Keys, Doors, and Windows
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 on page 5 48.
Keyless Locking
The doors lock after several
seconds if all doors are closed
and at least one keyless access
transmitter has been removed
from the interior of the vehicle.
To customize if the doors
automatically lock upon exiting the
vehicle, see "Keyless Locking"
under Vehicle Personalization on
page 5 48.
