Remote Keyless Entry
(RKE) System Operation
(Keyless Access)
The Keyless Access System
transmitter functions will work up to
60 m (195 ft) away from the vehicle.
The Keyless Access System lets
you lock and unlock the doors and
access the boot without removing
the remote transmitter from your
pocket, purse, briefcase, etc. The
keyless access transmitter must be
within 1 m (3 ft) of the door or boot
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
recognised, 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 always cause all of
the doors to unlock. This is not
customisable.
To customise which doors unlock
when the driver door is opened, see
Keyless Unlock under Vehicle
Personalisation on page 5 47.
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. It does not
matter how far away that one
transmitter is from the vehicle. To
customise whether the doors
automatically lock when you exit the
vehicle, see Keyless Locking
under Vehicle Personalisation on
page 5 47.
