Lane Departure Warning*
The concept
This system warns you from a speed of approx.
40 mph/70 km/h when the vehicle is leaving the
lane you are currently in on roads with lane limit
lines. You feel this due to a slight vibration of the
steering wheel.
The system does not warn you if you signal
before leaving the lane.
It is best to use the system on well-developed
roads and freeways.
Switching on/off
Press the button on the steering wheel.
>
The two lines
1 indicate that the system is
activated.
>
The two arrows
2 mean that the system has
detected one or two lane demarcation lines
from a speed of approx. 40 mph/70 km/h
and warns accordingly.
If you activate the system below a speed of
approx. 40 mph/70 km/h, a message will appear
stating that the system is not active until this
speed is reached.
A warning will be canceled:
>
after approx. 3 seconds
>
if you return to your lane
>
if you brake heavily
>
if you signal
System limits
The Lane Departure Warning cannot
serve as a substitute for your personal
judgment in determining the course of the road.

otherwise you could lose control of the vehi-
