#
Always pay particular attention to the
traffic situation when opening the doors
and make sure there is sufficient clear‐
ance.
If there is a vehicle in the monitoring range, this
is indicated in the outside mirror. If a vehicle
occupant opens the door on the side with the
warning, a warning tone sounds and the warning
lamp in the outside mirror starts to flash.
This additional function is only available when
Blind Spot Assist is active. When the exit warn‐
ing is activated, it can warn vehicle occupants
for up to three minutes after switching the igni‐
tion off. The exit warning is no longer available
once the warning lamp in the outside mirror
flashes three times.
The exit warning is only an aid and not a substi‐
tute for the attention of vehicle occupants. The
responsibility for opening and closing the doors
and for leaving the vehicle remains with the vehi‐
cle occupants.

Function of brake application (Active Blind
Spot Assist)
If Active Blind Spot Assist detects a risk of a side
impact in the monitoring range, a course-cor‐
recting brake application is carried out. This is
designed to help you avoid a collision.
The course-correcting brake application is availa‐
ble in the speed range between approximately
20 mph (30 km/h) and 125 mph (200 km/h).

WARNING Risk of accident despite
brake application of Active Blind Spot
Assist
A course-correcting brake application cannot
always prevent a collision.
