When the Distronic is deactivated, this
function will continue to warn you when
recognizing a stationary obstacle or a slower
vehicle moving in your vehicle's path and the
danger of a collision exists:

An intermittent warning will sound if

necessary.
If these warnings are issued, you must brake
manually to maintain a safe distance and
avoid a collision with the preceding vehicle.
When depressing the brake pedal, the
warning sound ceases. The warning sound
will also cease when the distance to the
preceding vehicle is sufficient again without
applying the brakes. In this case, the distance
warning lamp will also go out.

G Warning!
If the distance warning lamp l in the
instrument cluster comes on while driving
and/or an intermittent warning sounds,
immediate attention on the part of the
driver is required. As required by the traffic
situation, apply the brakes and navigate
around a possible obstacle. However, do
not drive by relying on the distance warning
function, as this will result in an emergency
braking application. This will not always
enable you to avoid a collision, especially
when traveling on varying road surface
conditions and with varying driver reaction.
Complex driving situations are not always

Hill start assist system

G Warning!
The hill start assist system is not designed
to function as a parking brake and does not
prevent the vehicle from moving when
parked on an incline.
Always engage the parking brake in
addition to shifting the automatic
transmission into park position P.
On uphill grades with a gradient angle of more
than 5°, the hill start assist system maintains
the pressure in the brake system for
approximately 1 second after you have
released the brake pedal. Therefore, you can
start off smoothly without the vehicle moving
immediately after releasing the brake pedal.
