General information
i The Driving Assistance package is only

Blind Spot Assist
Important safety guidelines
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. Blind Spot Assist provides assistance
at speeds higher than 20 mph (30 km/h). A
warning display in the exterior mirrors draws
your attention to vehicles in the monitored
area. If you then indicate a turn towards that
side before changing lanes, you will also
receive visual and audible collision warnings.
For this purpose, Blind Spot Assist uses
sensors in the rear bumper.GWarning
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some
vehicles and is no substitute for attentive
driving.
Blind Spot Assist cannot detect road and
traffic conditions. It may fail to detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.

grit and corrosive environmental factors may
cause flash rust to form on the surface. You
can restore the original shine of the exhaust
tail pipe by cleaning it regularly, especially in
winter and after washing.
! Do not clean the exhaust tail pipes with
alkaline-based cleaning agents, such as
wheel cleaner.
