Manual Speed Limiter  
Concept  
The system can be used to set a speed limit, for  
instance to prevent the vehicle from exceeding  
speed limits.  
Operation  
Switching on  
Press the button on the steering wheel.  
General information  
The system can limit the speed, starting at a  
value of 20 mph/30 km/h. The vehicle can be  
driven at any speed below the set speed limit.  
The current speed is accepted as the speed  
limit.  
If the system is switched on while the vehicle is  
stationary or driving at low speeds,  
20 mph/30 km/h is set as the speed limit.  
The marking in the speedometer is set to the re‐  
spective speed.  
When the speed limit is switched on, DSC Dy‐  
namic Stability Control and COMFORT driving  
mode may be switched on as well.  
Switching off  
Press the button on the steering wheel.  
The system switches off automatically in the fol‐  
lowing situations, for example:  
When the engine is switched off.

System limits  
If a vehicle driving ahead of you suddenly  
swerves into your lane, the system may not be  
able to automatically restore the selected dis‐  
tance. It may not be possible to restore the se‐  
lected distance in certain situations, including if  
you are driving significantly faster than vehicles  
driving ahead of you, for instance when rapidly  
approaching a truck. When a vehicle driving  
ahead of you is reliably detected, the system re‐  
quests that the driver intervene by braking and  
carrying out evasive maneuvers, if needed.  
Detection range  
Cornering  
The detection capacity of the system and the  
automatic braking capacity are limited.  
Two-wheeled vehicles for instance might not be  
detected.  
Deceleration  
The system does not decelerate in the following  
situations:  
If the desired speed is too high for a curve, the  
speed is reduced slightly, although curves can‐  
not be anticipated in advance. Therefore, drive  
into a curve at an appropriate speed.  
For pedestrians or similarly slow-moving road  
users.  
For red traffic lights.  
For cross traffic.  
The system has a limited detection range. Situa‐  
tions can arise in tight curves where a vehicle  
driving ahead will not be detected or will be de‐  
tected very late.  
For oncoming traffic.  
Swerving vehicles  
When you approach a curve the system may  
briefly report vehicles in the next lane due to the  
bend of the curve. If the system decelerates you  
may compensate it by briefly accelerating. After  
A vehicle driving in front of you is not detected  
until it is completely within the same lane as your  
vehicle.

General information  
An intermittent tone indicates when the vehicle  
is approaching an object. For instance, if an ob‐  
ject is detected to the left rear of the vehicle, a  
signal tone sounds from the left rear speaker.  
You may switch automatic activation when ob‐  
stacles are detected on and off.  
The shorter the distance to the object, the  
shorter the intervals.
