Is SL or ASL active?
Symbols in the instrument panel indicate whichfunction is active:

Sign symbolB after "70": ASL is acti-vated.

AWHITE symbol: the function is active, GRAY symbol: the func-tion is in standby mode.BSee the section "ASL symbol" below for an explanation of thesymbol's different colors.
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.

Activating/deactivating the
Automatic Speed Limiter (ASL)*
The function Automatic Speed Limiter (ASL) is asupplement to the Speed Limiter (SL) and canbe activated/deactivated.
ASL is activated/deactivated inthe center display's Functionview.
Activating ASL
With SL activated:
1.Tap the Speed Sign Assist button2 in thecenter display's Function view.
>ASL will go into standby mode and agreen indicator light in the button will illu-minate. A road sign symbol will be dis-played in center of the speedometer.
2.Press the button on the left-side steer-ing wheel keypad.
>ASL will be activated with the vehicle'scurrent speed.
Deactivating ASL
–Tap the Speed Sign Assist button in thecenter display's Function view.
>ASL will be deactivated, the indicator willbe GRAY and the Speed limiter (SL) willbe activated.
WARNING
After switching from ASL to SL, the vehiclewill no longer adapt speed to posted speedlimits. It will only limit the vehicle's maximumspeed.

•Automatic Speed Limiter (ASL)* (p. 269)
Changing tolerance for theAutomatic Speed Limiter
Automatic Speed Limiter can be set to differenttolerance levels.
Posted speed limit tolerance
ASL can be set to allow the vehicle to driveabove or below the posted speed limit. For exam-ple, if the current posted speed limit is 45 mph(75 km/h), the driver can opt to allow the vehicleto drive at a speed of 50 mph (80 km/h).
2If this button is tapped while SL is activated, ASL will immediately begin reading road signs.

Cruise Control (CC)
Cruise Control (CC) is designed to assist thedriver 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.
Overview

In models equipped with the optional AdaptiveCruise 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 drivenaccording 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.

Starting and activating CruiseControl
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

NOTE
Before CC can be activated, the vehicle'sspeed 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) onthe left-side steering wheel keypad.
>This puts CC in active mode and willmaintain 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 andholding 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 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.

AA
AIf the symbol is WHITE, the function is active. If the symbol isGRAY, the function is in standby mode.
Switching from ACC to CC
To switch from ACC to CC:
1.Put ACC in standby mode with the but-ton on the left-side steering wheel keypad.
2.From the center display's Function view, tapthe Cruise control button.
>The symbol in the instrument panel will
change from (ACC) to (CC) and CC is in standby mode (readyfor use but not currently maintaining a setspeed).
3.Press the button on the left-side steer-ing wheel keypad.
>CC goes into active mode and sets thevehicle's current speed.
WARNING
Switching from ACC to CC means that:
•Your vehicle will no longer automaticallymaintain a set distance to a vehicleahead.
•Only the set speed will be maintained andthe driver will have to apply the brakeswhen needed.
If CC was activated when the engine was turnedoff, ACC will be selected and go into standbymode when the engine is restarted.
Switching from CC to ACC
To switch from CC to ACC:
1.Put CC in standby mode with the buttonon the left-side steering wheel keypad.
2.In the center display's Function view, tap theAdaptive Cruise Control button.

Distance Alert*
Distance Alert is a function that alerts the driverif the time interval to the vehicle ahead is tooshort.
Distance Alert is active at speeds above approxi-mately 20 mph (30 km/h) and only reacts to avehicle ahead that is driving in the same direc-tion. No information is provided for vehicles driv-ing toward you, moving very slowly, or at a stand-still.
Warning light (generic illustration)
A warning light in the windshield glows steadily ifyour vehicle is closer to the one ahead than theset time interval.
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.
NOTE
Distance Alert only monitors distance to thevehicle ahead while Adaptive Cruise Control isin standby mode or off.
WARNING
Distance Alert only indicates the distance tothe vehicle ahead. It does not affect thespeed of your vehicle.

One bar between the vehicles represents a timeinterval of approximately 1 second; 5 bars isapproximately 3 seconds.
The same symbol appears if Adaptive CruiseControl is activated.
NOTE
•The greater the vehicles' speed, thegreater the distance between them for aset time interval.
•The set time interval is also used byAdaptive Cruise Control*.
•Only use time intervals permitted by localtraffic regulations.
