KEY, LOCKS AND ALARM
||
The sensor is located on left of centre in the bumper
One of the car's remote control keys must be
within range behind the car, approx. 1 metre
(3 feet), for opening and closing to be possible.
This also applies to an already unlocked car in
order to avoid accidental opening e.g. in a car
wash.
15 If the car is equipped with skid plate* the sensor is located out on the left-hand corner of the bumper.

Opening and closing with foot
movement
15
.
Kicking motion within the detector's activation area.
Make one slow, forward kicking motion
–
under the left part of the rear bumper. Then
take a step back. The bumper must not be
touched.
> A short acoustic signal sounds when
opening or closing is activated - the tail-
gate is opened/closed.
If several kicking motions take place without an
approved remote control key being located
behind the car, opening will not be possible until
after a certain delay.
Do not leave your foot positioned under the car
during the kicking motion. This could cause acti-
vation to fail.
Cancelling opening or closing with foot
movement
Make one slow forward kicking motion when
–
opening or closing is in progress in order to
stop the movement of the tailgate.
The remote control key does not have to be in
the vicinity of the car to cancel opening or closing
of the tailgate.
If the tailgate is stopped close to closed position,
the next activation will open the tailgate.
NOTE
There is a risk of reduced function, or no
function, if the rear bumper is loaded with
large amounts of ice, snow, dirt or similar. For
this reason, make sure you keep it clean.
NOTE
Pay attention to the possibility that the sys-
tem may be activated in a car wash or similar
if the remote key is within range.
Cars with the skid plate* accessory
If the car is equipped with skid plate the sensor is
located out on the left-hand corner of the
bumper.
* Option/accessory.
