• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is lim-ited in force, which means that it cannotalways help the driver to steer and keepthe vehicle within the lane.
• Pilot Assist is switched off if the powersteering is working with reduced power -e.g. during cooling due to overheating(see section "Speed-dependent steeringforce").
The driver can always correct or adjust steeringassistance provided by Pilot Assist by turning thesteering wheel to the desired position.
Steep roads and/or heavy loadsPilot Assist is primarily intended to be driven onflat roads. The function may not be able to main-tain the correct time interval to the vehicle aheadwhen driving down steep hills. The driver should be extra attentive and prepared to apply thebrakes.
• Do not use Pilot Assist if the vehicle is carry-ing a heavy load or towing a trailer.
NOTE
Pilot Assist cannot be activated if a trailer, bike carrier or similar is connected to thevehicle electrical system.
