Problems whe nprogramming
If you are experiencing problems programing
the integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
RCheck the transmitter frequency use dby
garage door drive remote control Aand
whethe ritissupported. The transmitter fre-
quency can usuall ybefound on the back of
the garage door drive remote control.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
RReplace the batteries in garage door remote
control A.This increases the likelihoo dthat
garage door remote control Awilltransmit a
strong and precis esigna ltot he integrated
garage door opener.
RWhen programming, hold remote control A
at varying distances and angle sfrom the but-
ton which you are programming. Try various
angle satad istance between 2and 12 inches
(5to 30 cm) or at the same angle but at varying
distances.
RIf another remote control is available for the
same garage door drive ,repeatt he same pro-
gramming steps with this remote control.
Before performing these steps, make sure
that new batteries have been installed in
garage door drive remote control A.
RNote that some remote controls only transmit
foralimited amount of time (the indicator
lam pont he remote control goes out). Press
button Bon remote control Aagain before
transmission ends.
RAlign the antenna cabl eofthe garage door
opener unit. This can improve signa lrecep-
tion/transmission.

Rstrong rubbingoft he paintwork with
unsuitable materials
Rfrequent use of automatic car washes
Rwashing the vehicle in directs unlight
!Never use paint cleaner, buffingorp olishing
products, or gloss preserver,e .g. wax. These
products are only suitable for high-gloss sur-
faces. Their use on vehicles with matt efinish
leads to considerable surfaced amage (shiny,
mottled areas).
Always have paintwork repairs carried out at a
qualified specialist workshop.
!Do not use wash programs with ahot wax
treatment under any circumstances.
Observe these notes if your vehicle has aclear
matt efinish. This will help you to avoid damage
to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with ac lear matt efinish.

MOExtended tire smay only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
