WARNING Risk of accident when chang‐
ing lane to an occupied adjacent lane
Lane Change Assist cannot always clearly
detect if the adjacent lane is free.
The lane change might be initiated although
the adjacent lane is not free.
#
Before changing lanes, make sure that
the neighbouring lane is free and there
is no danger to other road users.
#
Monitor the lane change.
&
WARNING Risk of accident if Lane
Change Assist unexpectedly stops func‐
tioning
If the system limitations for Lane Change
Assist have been reached, there is no guar‐
antee that the system will remain active.
Lane Change Assist cannot then assist you
by applying steering torque.
#
Always monitor the lane change and
keep your hands on the steering wheel.
Observe the traffic conditions and steer
and/or brake if necessary.
