Driving and Driving Safety
If the side windows in the driver’s or passenger’s
door are darkened with tinted film, the driver may
not be able to see the warning indicator on the
door mirror properly.
Detection area
The detection area of the radar sensors includes:
– the approach zone approx. 77 yd. (70 m) to
the rear and
– the blind-spot area.
The radar sensors cover the adjacent lane to the
left and right. Other lanes are
not
covered by the
radar sensors.
Information
Lane Change Assist does not measure the lane
width, but the system assumes that the lane has
a fixed width. The sensors cover this lane width at
the left and right.
When driving on narrow roads or when driving
off-center in a lane, it is possible that Lane Change
Assist will detect vehicles that are
not
in the very
next lane.
Operating principle
Lane Change Assist measures the distance and
speed difference of the detected vehicles
compared to your vehicle. Whenever Lane Change
Assist regards the speed difference and distance
as critical for changing lanes, this is indicated on
the relevant door mirror.
The warning indicator can light up when you are
overtaken by a vehicle or when you overtake
another vehicle.
When you overtake another vehicle slowly (speed
difference of less than 9 mph (15 km/h)), the
warning indicator lights up as soon as this vehicle
is in your blind-spot area and is detected by Lane
Change Assist. If there is a greater speed
difference, this is not indicated on the door mirror.
Information and Warning stage
Lane Change Assist has 2 warning indicator
stages:
– the information stage and
– the warning stage.
Depending on whether or not you have set the turn
signal to indicate that you intend to change lane,
Lane Change Assist helps you by activating the
relevant warning indicator stage.
Information stage
If you have not set the turn signal, Lane Change
Assist will inform you about detected vehicles that
will be regarded as critical for a possible lane
change. Whenever Lane Change Assist regards
the speed difference and distance of a detected
vehicle as critical, a weak light appears in the
warning indicator on the relevant door mirror.
The brightness of the information stage is
deliberately weak so as not to distract you while
driving without intending to change lanes and
looking at the road. The information stage is
clearly visible when you look in the door mirror.
Warning stage
When you set the turn signal and Lane Change
Assist has detected a vehicle on this side which it
regards as critical for changing lanes, the warning
indicator on the mirror on this side will start to
flash brightly. When the warning stage flashes
brightly several times, this should be an indication
for you to check the driving situation again by
looking in the door mirror and looking over your
shoulder.
Information
The brightness of the warning indicator on the
door mirror can be changed.
