CONTROLS
Steering intervention
Depending on the national-market version:
when there is no response to the vibration of
the steering wheel at speeds of up to
130 mph/210 km/h and the lane marking is
crossed, the system engages the active steer-
ing intervention. The steering intervention
helps return the vehicle into the lane. The
steering intervention can be noticed on the
steering wheel and can be manually overrid-
den at any time.
The steering intervention occurs when a mini-
mum speed is reached. The minimum speed is
displayed on the control display.
Flashing of the light
A flashing of the light in exterior mirror during
vehicle unlocking serves as system self-test.
System limits

ing systems" chapter.

155 mph/250 km/h, the system is deactivated
temporarily.

sponds according to the setting.

uations.
