Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
If Blind Spot Assist is activated, warning lamp 0043
in the exterior mirrors lights up yellow at speeds
of up to 20 mph (30 km/h). At speeds above
20 mph (30 km/h), the warning lamp goes out
and Blind Spot Assist is operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp 0043on the correspond-
ing side lights up red. This warning is always
emitted when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
7 mph (12 km/h).
If you select the reverse gear, Blind Spot Assist
is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. The red warning lamp flashes on the
relevant exterior mirror. If the turn signal
remains on, detected vehicles are indicated by
the flashing of the red warning lamp on the exte- rior mirror. No further warning tone sounds.
Activating Blind Spot Assist
X Make sure that Blind Spot Assist is activated
in the on-board computer (Y page 168).
X Select SmartKey position 0048with the Start/
Stop button.
Warning lamps in the exterior mirrors light up red for approximately 1.5 seconds and then
turn yellow. Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era 0043which is attached behind the top of the
windshield. Lane Keeping Assist detects lane
markings on the road and can warn you before
you leave your lane unintentionally.
This function is available in the range between
40 mph and 120 mph (60 km/h and 200 km/h).
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of intermittent vibration in the steering wheel for
up to 1.5 seconds.
Important safety notes G

detect lane markings.
In such cases, Lane Keeping Assist can:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Lane Keeping Assist alerts you. G
WARNING

tons 0044to0085 on the rear-view mirror at a dis-
tance of 2 to 8 in (5 to 20 cm).

When indicator lamp 0043flashes green: pro-
gramming was successful. The next step is to
synchronize the rolling code (Y page 232).
X Release button 0084on remote control 0083for
the garage door drive system.
If indicator lamp 0043lights up red: repeat the
programing procedure for the corresponding
button on the rear-view mirror. When doing
so, vary the distance between remote control
0083 and the rear-view mirror.
The required distance between remote con-
trol 0083and the integrated garage door opener
depends on the garage door drive system. Several attempts might be necessary. You
should test every position for at least
25 seconds before trying another position.
Synchronizing the rolling code
Pay attention to the "Important safety notes"
(Y page 231).
If the garage door system uses a rolling code,
you will also have to synchronize the garage
door system with the integrated garage door
opener in the rear-view mirror. To do this you will
need to use the programming button on the door
drive control panel. The programming button
may be located in different places depending on the manufacturer. It is usually located on the
door drive unit on the garage ceiling.
Familiarize yourself with the garage door drive
operating instructions, e.g. under "Program-
ming additional remote controls", before carry-
ing out the following steps.
Your vehicle must be within reach of the garage
door or gate opener drive. Make sure that nei-
ther your vehicle nor any persons/objects are
present within the sweep of the door or gate.
X Select SmartKey position 0048with the Start/
Stop button (Y page 111).
X Get out of the vehicle.
X Press the programming button on the door
drive unit.
You now have 30 seconds to initiate the next
step.
X Get into the vehicle.
X Press previously programed button 0044,0087
or 0085 on the integrated garage door opener
repeatedly until the door closes.
The rolling code synchronization is then com- plete.
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 garage door opener. The signal is not recognized during programming. Comparable
with Canadian law, some U.S. garage door open-
ers also feature a "break". 232
