Narrow or staggered vehicle
ACC detects a narrow or staggered vehicle only
when it is in the area covered by the radar.
Lane change by another vehicle
A vehicle that changes to the lane a short distance
away may not be recognized by the ACC in time.
Stationary vehicle
If a vehicle in front turns and there is a stationary ve-
hicle in front of this vehicle, the ACC will not respond
to the stationary vehicle.
Vehicles with special load or special bodies
A load or superstructure that protrudes outside the
vehicle might not be detected by the ACC.

Lane Assist
Usage
Lane Assist helps to keep the vehicle between the
continuous and broken lines of a lane.
The system is intended primarily for use on high-
ways.
Functionality
As the vehicle approaches a lane marking, the sys-
tem executes a steering movement in the opposite
direction from the lane marking. The steering inter-
vention can be overridden manually.
No system intervention occurs when changing lane
with the turn signal on.
