Automatic Speed Limiter (ASL)*
The Automatic Speed Limiter (ASL) helps thedriver adapt the vehicle's maximum speed to theposted speed limits.
The Speed Limiter (SL) function can be switchedto Automatic Speed Limiter.
Where applicable, ASL uses speed informationfrom the Road Sign Information* system to auto-matically adapt the vehicle's maximum speed.
WARNING
•ASL is a supplemental aid to the driverand does not function in all driving situa-tions or in all traffic, weather or road con-ditions. It can never replace the driver

ASL symbol
A road sign symbol (next to the storedspeed in the center of the speedome-ter) can be displayed in three differentcolors as explained in the followingtable:
Road signsymbol's colorExplanation
Green/yellowASL is active
GrayASL is in standby mode
Amber/orangeASL is temporarily in standbymode (e.g., because a speedlimit sign could not be read)
Limitations
•ASL utilizes the speed limit information provi-ded by the Road Sign Information* system(RSI), not from the speed limit signs that thevehicle passes.
•If RSI cannot provide ASL with speed-relatedinformation, ASL will go into standby modeand switch to SL. The driver will have to reactand adapt the vehicle's speed.
•ASL will reactivate when RSI is once againable to read a speed limit sign.

pedal before the button is pressed, the vehi-cle's speed when the button is pressed will
become the set speed assuming that the accel-erator pedal is still depressed when the button ispressed.
A temporary increase in speed, such as whenpassing another vehicle, does not affect the CCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released. Alwaysobserve posted speed limits.

Engine braking instead of applying the
brakes
CC regulates speed by applying the brakeslightly. To avoid a loss of speed when drivingdown hills, use the engine braking functioninstead of letting the CC apply the brakes. In thissituation, the driver can temporarily deactivate theCC braking function.
To do so:
–Press the accelerator pedal approx. halfwaydown and release it.
>CC will automatically deactivate the auto-matic brake function and will then onlyuse the engine braking function.
