5. "Speed Limit Assistance"
6. "Adjust to route"
System limits
Speed Limit Assist is based on the Speed Limit
Info system.
Consider the system limits of Speed Limit Info.
Upcoming speed limits can only be applied for
the Active Cruise Control ACC.
The system may not respond at all or with limita‐
tions to the route when the navigation system is
unable to clearly identify the position of the vehi‐
cle.
Additional information:
▷ System limits of Speed Limit Information, re‐
fer to page 166.
▷ System limits of the sensors, refer to
page 35.
Steering Assistant
Concept
The system assists the driver in keeping the ve‐
hicle within the lane. For this purpose, the sys‐
tem executes supporting steering movements,
for instance when driving in a curve.
General information
Depending on the speed, the system orients it‐
self according to the lane markings or vehicles in
front.
Sensors on the steering wheel detect whether
the steering wheel is being touched.
Safety information
Warning
The system cannot serve as a substitute for the
driver’s personal judgment in assessing the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is a risk of accident. Adjust
driving style to traffic conditions. Watch traffic
closely and actively intervene where appropri‐
ate.
