Problems when programming
If you are experiencing problems
programmingthe integrated garage door
opener on the rear-view mirror, take noteof
the following instructions:
RCheck the transmitter frequencyofgarage
door drive remotecontrol.This can
usually be found on the back of the remote
control.
The integrated garage door opener is
compatible with devices that have units
which operate in the frequency range of
280to433MHz.
RReplace the batteries in garage door
remote control.This increases the
likelihood that garage door remote control
will transmitastrongand precisesignal
to the integrated garage door openerinthe
rear-view mirror.
RWhen programming, hold remote control
at varying distances and angles from the
button that you are programming. Try
various angles atadistance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
RIf another remote control for the same
garage door drive is available, repeat the
same programming steps with this remote
control. Before performing these steps,
make sure that new batteries have been
installed in garage door drive remote
control.
RNote that some remote controls only
transmit foralimited amount of time (the
indicator lamp on the remote control goes
out). Press button%on remote control
again before transmission ends.
RAlign the antennacable of the garage door
opener unit. This can improve signal

your vehicle even if there isatotal loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognizeMOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-
bearing capacity and the speed index
(Ypage 351).
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If the pressureloss warning message
appearsinthe multifunction display:
RObserve the instructions in the display
messages (Ypage 258).
RCheck the tire for damage.
RIf driving on, observe the following notes.
The maximum driving distance is
approximately 50 miles (80 km) when the
