the loading guidelines.
Otherwise, vehicle occupants could
be injured by the load being thrown around in
the even tofsharp braking, a sudden change
in direction or an accident.

should observe the following notes when
transporting a load:
R when transporting a load, never exceed the
maximum permissible gross vehicle weight or the permissible axle loads for the vehicle
(including occupants).
R position heavy loads as far forwards as pos-
sible and as low down in the boot as pos-
sible.
R the load must not protrude above the upper
edge of the seat backrests.
R always place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place.
R always place the load behind unoccupied
seats if possible.

Problems when programming
If you have problems when programming the
integrated garage door opener, please note
the following:
R Check the transmitter frequency of garage
door drive remote control A.This can usu-
ally be found on the back of the remote
control.
R Replace the batteries in garage door
remote control A.This increases the like-
lihood that garage door remote control A
will transmit a strong and precise signal to
the integrated garage door opener in the
rear-view mirror.
R When programming, hold remote control
A at varying distances and angles from the
button which you are programming. Try var-
ious angles at a distance between 5and
30 cm or at the same angle but at varying
distances.
R If there is another remote control for the
same garage door drive, perform the pro-
gramming steps again using this remote
control. Before performing these steps,
make sure that new batteries have been
fitted in garage door drive remote control
A.
R Note that some remote controls transmit
only for a limited period (the indicator lamp
on the remote control goes out). Press but-
ton Bon remote control Aagain before
transmission ends.
