speed +/– 1 mph (+/– 1 km/h) at a time.Release the button when the indicator (4)has moved to the desired maximumspeed.
LimitationsWhen driving down steep hills, the SpeedLimiter's braking effect may not be adequate andthe set maximum speed may be exceeded. The message
Speed limit exceeded will appear in
the instrument panel to alert the driver.
NOTE
This message will appear if the maximum speed is exceeded by more than approx.2 mph (3 km/h).

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

–Press the button (1) until 43 mph
(70 km/h) has changed to 47 mph (75 km/h) in the center of the speedometer (4).
> The vehicle will then use the selected tol-
erance +4 mph (+5 km/h) until the vehi- cle passes a sign with a lower or higherspeed limit. The vehicle will then adjust tothe new maximum speed and the set tol-erance will be deleted from the system'smemory. If the Road Sign Information * system is
activated, the posted speed limit will be indicated by a RED marker on the spee-dometer's speed scale. The set tolerance can be adjusted in the same way as the Speed Limiter's setmaximum speed.
NOTE
The greatest tolerance that can be set is +/– 5 mph (10 km/h).

–Press the button (1).
> The maximum speed marker (4) and sym- bols will change colors to WHITE and the vehicle's maximum speed will be limited tothe previously set maximum speed.
or
–Press the button (2).

Cruise Control (CC)
Cruise Control (CC) is designed to assist the driver by maintaining a set speed. It is primarilyintended for use on long straight roads in steadytraffic, such as on highways and other mainroads in smoothly flowing traffic.

In models equipped with the optional Adaptive Cruise Control (ACC), the driver can togglebetween CC and ACC – see the article "Switch-ing between Cruise Control and Adaptive CruiseControl".
WARNING
• The vehicle must always be driven according to current traffic/road condi-tions. The driver must take action if CCdoes not maintain a suitable speedand/or distance to other vehicles.
• The driver is always responsible for oper-ating the vehicle in a safe manner.

Cruise Control (CC) must be selected and acti- vated before it can regulate the vehicle's speed.
Selecting CC (putting it in standby
mode)
Function buttons and symbols
–Press ◀ (1) or ▶ (3) to scroll to the CC
(

* Option/accessory.271
NOTE
Before CC can be activated, the vehicle's speed must be at least 20 mph (30 km/h).This is also the lowest speed that can be set.
Activating CC (putting it in active mode and setting a speed)
–With the symbol displayed (CC is in
standby mode), press the
button (2) on
the left-side steering wheel keypad.
> This puts CC in active mode and will maintain the vehicle's current speed.

Changing Cruise Control speed
Changing a set speed
Function buttons and symbols (generic illustration)
–Change a set speed by pressing the (1)
or — (3) buttons briefly or by pressing and
holding them:
• Press briefly
: changes speed in
+/– 5 mph (+/– 5 km/h) increments. Each press changes the vehicle's speedby +/– 5 mph (+/– 5 km/h).
• Press and hold
: changes the speed
+/– 1 mph (+/– 1 km/h) at a time.Release the button when the set speedindicator (4)/(6) has moved to the desiredspeed.
If speed is increased by pressing the accelerator 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 when passing 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. halfway down and release it.
> CC will automatically deactivate the auto- matic brake function and will then only use the engine braking function.

Deactivating/resuming Cruise Control (CC) Cruise Control (CC) can be temporarily deacti- vated and put in standby mode.
Deactivating and putting CC in standbymode
To temporarily deactivate and put Cruise Control in standby mode:
Function buttons and symbols (generic illustration)
–Press the button (2).
> The set speed marker (4) and symbols will change colors from WHITE to GRAY. This indicates that CC is temporarily in standby mode and will not maintain a setspeed.
Standby mode due to action by the driver
CC is temporarily deactivated and put in standby mode if:
• the brakes are applied
• The gear selector is moved to
N
• the vehicle is driven faster than the setspeed for more than 1 minute.
In these cases, the driver will have to regulate thevehicle's speed. A temporary increase in speed, such as when passing another vehicle, does not affect the CCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released.
Automatic standby mode
CC switches automatically to standby mode if:
• the wheels lose traction
• engine speed (rpm) is too high/low
• brake temperature is too high
• the vehicle's speed goes below approx. 20 mph (30 km/h)
In these cases, the driver will have to regulate thevehicle's speed.
Reactivating CC from standby modeTo reactivate CC after it has temporarily been putin standby mode:
–Press the button (1).
> The set speed marker (4) will change color from GRAY to WHITE. The vehicle will then return to the most recently set
speed .
WARNING
There may be a significant increase in speed after the
button has been pressed.

Collision warning
Warning light in the windshield
Adaptive Cruise Control can exert brake force that is equivalent to approximately 40% of thevehicle's total braking capacity. In situations requiring more brake force than ACC can provide and if the driver does not applythe brakes, an audible signal from the City Safetysystem will sound and warning light will illuminatein the windshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.
