WARNING
When the memory function adjusts the seat or steering wheel, you and other vehicle occu-
pants – particularly children – could become
trapped. There is a risk of injury.
While the memory function is making adjust-
ments, make sure that no one has any body
parts in the sweep of the seat or steering
wheel. If somebody becomes trapped, imme-
diately release the memory function position
button. The adjustment process is stopped. G
WARNING
Children could become trapped if they acti-
vate the memory function, particularly when
unattended. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle.
With the memory function, you can store up
to three different settings, e.g. for three dif-
ferent people.
The following settings are stored as a single
memory preset:
R position of the seat, backrest and head
restraint
R driver's side: steering wheel position
R driver's side: position of the exterior mir-
rors on the driver's and front-passenger
sides X
Make sure that the SmartKey is in position
2 (Y page 133) or that the respective door
is open.
X Adjust the seat (Y page 86) and head

if there are unpleasant outside odors or when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.

Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 248 ‡ (120 †). Tachometer

Important safety notes
G
WARNING
When you operate or program the garage door with the integrated garage door opener, per-
sons in the range of movement of the garage
door can become trapped or struck by the
garage door. There is a risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garage
door. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
When programming a garage door opener,
park the vehicle outside the garage. Do not
run the engine while programming.

X Repeat the procedure for the other trans-
mitter buttons. When doing so, vary the
distance between the garage door's
remote control and the transmitter buttons
in the rear-view mirror.
i If the garage door system works with a
rolling code, you must synchronize the
remote control integrated in the rear-view
mirror with the garage door system
receiver after programming.
You will find further information in the
garage door opening system's operating
instructions, e.g. the sections on "Synchro- nizing the transmitter" or "Registering a
new transmitter". You can also call the hot-
line mentioned above.

tion lock (Y page 133).
X Press the programming button of the door

Notes on programming the remote con-
trol
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds.
Therefore, these signals may not last long
enough for the integrated remote control to
recognize the signal during programming.
Comparable with Canadian law, American
garage door openers also have a built-in
"interruption".
If you live in Canada or have difficulties pro-
gramming the garage door opener (regard-
less of where you live) when using the pro-
gramming steps, proceed as follows: 268

If you have problems when programming the
integrated remote control, please note the
following:
R Check the transmitter frequency of garage
door remote control A(which can usually
be found on the back of the remote con-
trol).
The integrated remote control is compati-
ble with devices that have units which oper- ate in the frequency range of 280 to
390 MHz.
R replace the batteries in garage door remote
control A. This increases the probability of

strong and precise signal to the integrated
remote control on the rear-view mirror.
R When programming, hold garage door
remote control Aat varying distances and
angles from the transmitter button which
you are programming. Try various angles at a distance between 2 and 12 inches (5 to
30 cm) or at the same angle but at varying distances.
R If there is another garage door remote con-
trol for the same device, perform the pro-
gramming steps again using that garage
door opener. Before performing these
steps, make sure that new batteries have Features
