The driver is responsible for ensuring that the vehicle maintains a suitable distancefrom such obstacles.
• The camera and radar sensors do nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects that completely or partiallyblock the route.
• 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.
Other limitations
•
The Off Road drive mode cannot be
selected when Pilot Assist is activated.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".

•
for smaller vehicles such as motorcycles
• on roads that do not have clear lane mark- ings
• if more than half of your vehicle has movedinto the adjacent lane
• outside the speed range 60-140 km/h(37-87 mph)
• when the power steering works at reducedpower - e.g. during cooling due to overheat-ing (see section "Speed-dependent steeringforce").
Functionality may also be reduced in other situa-tions, such as: • road work
• winter driving conditions
• narrow roads
• poor road surfaces
• a very sporty driving style
