refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the wrong fuel could result in damage to the
fuel system and the engine. Notify a quali-
fied specialist workshop and have the fuel
tank and fuel lines drained completely.
!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel can.

ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the 37 mph (60 km/h) to 125 mph
(200 km/ h)range. If ATTEN-
TION ASSIST detects typical indicators of fati-
gue or increasing lapses in concentration on
the part of the driver, it suggests taking a
break.
Important safety notes
ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.

Problems when programming
If you are experiencing problems programing
the integrated garage door opener on the
rear-view mirror, take note of the following
instructions:
R Check the transmitter frequency used by
garage door drive remote control Aand
whether it is supported. The transmitter
frequency can usually be found 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.
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.
R When programming, hold remote controlA at varying distances and angles from the
button which you are programming. Try var- ious angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
R If another remote control is available for the
same garage door drive, repeat the same
programming steps with this remote con-
trol. Before performing these steps, make
sure that new batteries have been installed
in garage door drive remote control A.
R Note that some remote controls only trans-
mit for a limited amount of time (the indi-
cator lamp on the remote control goes out).
Press button Bon remote control Aagain
before transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal recep-tion/transmission.
