Changing Automatic Speed Limitertolerance The Automatic Speed Limiter (ASL 23
) can be set
to different tolerance levels.
It is also possible to allow the vehicle to drive above or below the posted speed limit. For exam-ple, if the vehicle is following a current postedspeed limit of 70 km/h (43 mph), the driver caninstead allow the vehicle to maintain a speed of75 km/h (47 mph).
Function buttons and symbols 24
.
–Tap the (1) button on the steering
wheel keypad until 70 km/h (43 mph) has been changed to 75 km/h (47 mph) in thecenter of the speedometer (4).
> The vehicle will then use the selected tol- erance of 5 km/h (4 mph) as long as the posted speed limit the vehicle passes is70 km/h (43 mph). This tolerance level will be followed until the vehicle passes a sign with a lower orhigher speed. The vehicle will then adjustto the new speed limit and the set toler-ance will be deleted from the system'smemory. If Road Sign Information * is activated, the
posted speed limit will then be indicated by a RED marking on the speedometer'sspeed scale.
The set tolerance can be adjusted in the sameway as for the Speed Limiter's speed.
NOTE
The highest possible selectable tolerance is +/- 10 km/h (5 mph).

Automatic Speed Limiter limitations
ASL utilizes the speed limit information provided by the RSI 25
system, not from the speed limit
signs that the vehicle passes.
If RSI 25
is unable to interpret and provide ASL
with speed information, ASL will go into standby mode and switch over to SL. The driver will thenhave to actively brake to bring the vehicle downto the appropriate speed. ASL will be reactivated when RSI 25
is once again
able to interpret and provide speed information to ASL. See "Road Sign Information limitations" for more information.

Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, will not affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applyingthe brakes. On downgrades, it can sometimes bedesirable to roll a bit faster and let speed bereduced instead by engine braking alone. Thedriver can temporarily disengage the Cruise Con-trol braking function. To disengage CC:
–Press the accelerator pedal about halfway down and then release it.
> Cruise Control will automatically disen- gage the automatic brake function and speed will only be reduced using theengine braking function.

Cruise Control Eco Cruise
In the ECO drive mode, cruise control's accelera- tion and deceleration will be smoother than inother drive modes to help provide optimal fuelefficiency and reduced environmental impact.Because of this, the vehicle's actual speed maybe slightly above or below the set speed. For more information, see "ECO drive mode" under "Eco Cruise".
Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control's acceleration and deceleration will be faster andmore immediate than in other drive modes.

tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic standby mode
Adaptive Cruise Control is dependent on other systems, such as Electronic Stability Control (ESC 50
). If any of these other systems stops
working, Adaptive Cruise Control will automati- cally switch off.
WARNING
With automatic standby mode, the driver is warned by an acoustic signal and a messageon the instrument panel. • The driver must then regulate vehicle speed, apply the brakes if necessary, andmaintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standbymode if: • your vehicle's speed goes below 5 km/h(3 mph) and ACC cannot determine if thevehicle ahead is stationary or if it is anotherobject, e.g. a speed bump.
• your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatACC no longer has a vehicle to follow. •
the driver opens the door.
• the driver unbuckles the seat belt.
• the engine speed (rpm) is too low/high.
• one or more of the wheels lose traction.
• the brake temperature is high.
• the parking brake is applied.
• the camera/radar sensor is covered by snowor heavy rain (the camera lens/radar wavesare blocked)

Passing assistance with AdaptiveCruise Control Adaptive Cruise Control (ACC 51
) can assist the
driver when passing other vehicles.
How passing assistance worksWhen ACC is following another vehicle and you indicate that you intend to pass that vehicle by using the turn signal 52
, Adaptive Cruise Control
will begin accelerating toward the vehicle ahead before your vehicle has moved into the passing
lane. The function will then delay a speed reduction to avoid early braking as your vehicle approaches aslower-moving vehicle. The function remains active until your vehicle has passed the other vehicle.
WARNING
Please note that this function can be acti- vated in more situations than just passinganother vehicle, such as when a direction indi-cator is used to indicate a lane change orbefore exiting to another road – the vehiclewill then briefly accelerate.

Pilot Assist
Pilot Assist helps the driver keep the vehicle in the current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.
How Pilot Assist worksThe Pilot Assist function is primarily intended for use on highways and other major roads where itcan help provide a more comfortable and relaxingdriving experience.
The camera/radar sensor monitors the distance to the vehicle ahead and detects lane markings 62
.
Camera and radar sensor
Distance monitor
Lane marker line monitors The driver sets the desired speed and distance to the vehicle ahead. Pilot Assist monitors the dis-tance to the vehicle ahead and the traffic lane'sside markers using the camera and radar sensor.The system maintains the set time interval to thevehicle ahead by automatically adjusting yourvehicle's speed and keeps your vehicle in its laneby providing steering assistance. Pilot Assist's steering assistance is based on monitoring the direction of the vehicle ahead andthe traffic lane's side marker lines. The driver canoverride Pilot Assist's steering recommendationsat any time and steer in another direction, e.g. tochange lanes or avoid obstacles on the road. If the camera/radar sensor cannot detect the lane's side marker lines or if Pilot Assist is unablefor some other reason to clearly interpret thelane, Pilot Assist will temporarily deactivate steer-ing assistance until it can once again interpretthe lane markings. However, the speed and dis-tance warnings will remain active.
WARNING
Pilot Assist is deactivated automatically and resumes working without prior notice.
The color of the steering wheel symbol indicates the currentstatus of steering assistance: • GREEN indicates that steer- ing assistance is active • GRAY (as shown in illustra-
tion) indicates that steering assistance is deacti- vated.

Pilot Assist's steering assis- tance is only active when thesteering wheel symbol (2)changes from GRAY toGREEN. Pilot Assist will only regulate
the time interval to the vehicle ahead when the distance symbol shows a vehicle (1) over thesteering wheel symbol.
A speed interval will be marked at the same time. The higher speed is the set speed for your vehicle and thelower speed is the speed of thevehicle ahead (target vehicle).
Hands on the steering wheelPilot Assist only functions if the driver's hands are on the steering wheel. If Pilot Assist detectsthat the driver's hands are not on the steeringwheel, the driver will be instructed to activelysteer the vehicle by a text message and an audi-ble signal. If Pilot Assist still cannot detect the driver's hands on the steering wheel, the function will gointo standby mode. Pilot Assist must then be reactivated by pressing the
button on the
steering wheel.
NOTE
Note that the Pilot Assist function only works when the driver's hands are on the steeringwheel.
