Setting display brightness on door mirror
The brightness of the warning indicator for both
the information stage and warning stage is
automatically adjusted according to the ambient
brightness.
You can also adjust the basic brightness as
required on the multi-purpose display.
f
Please see the chapter “LANE CHANGE
ASSIST (LCA)” on page 131.
The new brightness is displayed briefly during the
setting process. This is the level of brightness
displayed for the information stage. The
brightness of the warning stage depends on the
brightness of the information stage.
f
Set the brightness of the information stage so
that you can clearly see the warning indicator
lighting up when you look in the door mirror,
but cannot see it when you look straight ahead
through the windshield.
In very dark or bright surroundings, the warning
indicator may already be at the lowest or highest
level of automatic brightness adjustment. In such
cases, there may not be any noticeable change in
the brightness of the warning indicator on the door
mirror when you adjust the basic brightness.
When you change the basic brightness in very
bright or dark surroundings, you may not notice
any change until you are back in an area with
moderate ambient brightness.
Information
– Lane Change Assist is not active while you are
adjusting the brightness. The warning indicator
lights up briefly only to help you to set the
brightness.
– Your settings are automatically stored and
assigned to the radio key you are using.
General information
System-related limits are set for Lane Change
Assist while driving. Please drive with extreme
care therefore:
– when driving around corners
– when driving in lanes that are not of standard
width.
When driving around corners
– Lane Change Assist cannot detect vehicles in
tight corners (corner radius of less than
109 yd. (100 m)).
– When driving around a corner, Lane Change
Assist may react to a vehicle driving two lanes
over from you and the warning indicator on the
door mirror may light up.
Lane width
– The Lane Change Assist detection area is
designed in such a way that it covers the two
adjacent lanes (left and right) on lanes of
standard width regardless of whether you are
driving exactly in the middle or more on the
edge of your lane.
– When you are driving on narrow lanes, this area
may cover even more lanes, particularly if you
are driving at the edge of your lane.
In situations like this, vehicles driving two lanes
over from you can also be detected and Lane
Change Assist could switch to the information
or warning stage.
– Likewise, when driving on very wide lanes,
vehicles in the next lane may not be detected
because they are outside of the detection
area.
