Automatic headlamp mode G
WARNING
When the light switch is set to Ã, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
L.
The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's
lighting at all times.
à is the favored light switch setting. The
light setting is automatically selected
according to the brightness of the ambient
light (exception: poor visibility due to weather
conditions such as fog, snow or spray):
R SmartKey in position 1in the ignition lock:
the parking lamps are switched on or off
automatically depending on the brightness
of the ambient light.
R With the engine running: if you have
activated the daytime running lamps
function via the on-board computer, the
daytime running lamps or the low-beam
headlamps and parking lamps are switched
on or off automatically depending on the
brightness of the ambient light.
X To switch on automatic headlamp
mode: turn the light switch to Ã.
Only for Canada:
The daytime running lamps improve the
visibility of your vehicle during the day. The
daytime running lamps function is required by
law in Canada. It cannot therefore be
deactivated. When the engine is running and the vehicle is
stationary: if you move the selector lever from
a drive position to
P, the daytime running
lamps/low-beam headlamps go out after
three minutes.
When the engine is running, the vehicle is
stationary and in bright ambient light: if you
turn the light switch to T, the daytime
running lamps and parking lamps switch on.
If the engine is running and you turn the light
switch to L, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the
visibility of your vehicle during the day. To do
this, the daytime running lamps function must
be switched on using the on-board computer
(Y page 161).
If the engine is running and you turn the light
switch to TorL, the manual settings
take precedence over the daytime running
lamps.
Low-beam headlamps G
WARNING
When the light switch is set to Ã, the low-
beam headlamps may not be switched on

causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
L.
Even if the light sensor does not detect that
it is dark, the parking lamps and low-beam
headlamps switch on when the ignition is
switched on and the light switch is set to the
L position. This is a particularly useful
function in the event of rain and fog.
X To switch on the low-beam headlamps:

Important safety notes G
WARNING
If children are left unsupervised in the vehicle,
they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shifting the automatic transmission out of
park position P
R Start the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children. 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
without sufficient ventilation. G
WARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
! Do not depress the accelerator pedal
when starting the engine.

Notes on programming the remote
control
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 garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers also
feature a "break".
Proceed as follows:
R if you live in Canada
R if you have difficulties programming the
garage door opener (regardless of where
you live) when using the programming

Problems when programming
If you are experiencing problems
programming the integrated garage door
opener on the rear-view mirror, take note of
the following instructions:
R Check the transmitter frequency of garage
door drive remote control A. 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
280to 433MHz.
R Replace the batteries in garage door
remote control A. This increases the
likelihood 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 that you are programming. Try
various 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 for the same
garage door drive is available, repeat the Features
