Starting/activating Adaptive Cruise
Control
To start ACC:
The driver's seat belt must be buckled andthe driver's door must be closed.
There must be a vehicle ahead (target vehi-cle) within a reasonable distance or yourvehicle's current speed must be at least15 km/h (9 mph).
–With the (4) function displayed, press
(1) on the steering wheel keypad.
>Adaptive Cruise Control will start and thecurrent speed will be stored, which will beshown by numbers in the center of thespeedometer.
ACC will only regulate the timeinterval to the vehicle aheadwhen the distance symbolshows two vehicles.
A speed interval will be markedat the same time.
The higher speed is the setspeed for your vehicle and thelower speed is the speed of thevehicle ahead (target vehicle).

To temporarily deactivate Adaptive Cruise Controland put it in standby mode:
–Press the button on the steering wheel(2).
>The symbol in the instrument panelchanges color from WHITE to GRAY andthe set speed in the center of the speed-ometer will change from BEIGE to GRAY.
WARNING
If Adaptive Cruise Control is in standbymode, the driver must intervene and regu-late both speed and distance to the vehicleahead.
If the vehicle comes too close to a vehicleahead when Adaptive Cruise Control is instandby mode, the driver can be warned ofthe short distance by the Distance Alert*function.
Standby mode due to action by the driver
Adaptive Cruise Control will be temporarily deac-tivated 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
Temporarily increasing speed using the accelera-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 othersystems, such as Electronic Stability Control
(ESC25). If any of these other systems stopsworking, Adaptive Cruise Control will automati-cally switch off.
WARNING
With automatic standby mode, the driver iswarned by an acoustic signal and a messageon the instrument panel.
The driver must then regulate vehiclespeed, 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).

Adaptive Cruise Control* limitations
Adaptive Cruise Control (ACC26) may have lim-ited functionality in certain situations.
Steep roads and/or heavy loads
Adaptive Cruise Control is primarily intended tobe driven on flat roads. The function may not beable to maintain the correct time interval to thevehicle ahead when driving down steep hills. Thedriver should be extra attentive and prepared toapply the brakes.
Do not use Adaptive Cruise Control if thevehicle is carrying a heavy load or towing atrailer.
Other limitations
The Off Road drive mode cannot beselected if Adaptive Cruise Control is acti-vated.
NOTE
The function uses the vehicle's camera andradar sensor, which has certain general limita-tions.

Note: This illustration is general and details may varydepending on model.
To start Pilot Assist:
The driver's seat belt must be buckled andthe driver's door must be closed.
There must be a vehicle ahead (target vehi-cle) within a reasonable distance or yourvehicle's current speed must be at least15 km/h (9 mph).
With Adaptive Cruise Control in standby mode:
1.Press the ▶ button on the steering wheel (6).
>The symbol will change to PilotAssist in standby mode (8).
2.Press the button on the steering wheel(2).

>Pilot Assist will start.
Pilot Assist's steering assis-tance is only active when thesteering wheel symbol (2)changes from GRAY toGREEN.
Pilot Assist will only regulatethe time interval to the vehicle ahead when thedistance symbol shows a vehicle (1) over thesteering wheel symbol.
A speed interval will be markedat the same time.
The higher speed is the setspeed for your vehicle and thelower speed is the speed of thevehicle ahead (target vehicle).
Hands on the steering wheel
Pilot Assist only functions if the driver's handsare on the steering wheel.
