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.

The Distance Alert 34
function can help the driver
become aware if the time interval to the vehicle in front is too short. However, the vehicle must be equipped with a head-up display in order to display the DistanceAlert, which will then be indicated by a symbolon the windshield as long as the time interval tothe vehicle ahead is shorter than the set timeinterval.
Distance Alert is active at speeds above 30 km/h (20 mph) and only reacts for vehicles ahead mov-ing in the same direction as your vehicle. No dis-tance information is provided for oncoming, slow-moving or stationary vehicles.

WARNING
• If Adaptive Cruise Control is in standby mode, 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 is instead warnedof the short distance by the Distance Alertfunction.
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 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.

Requirements for passing assistanceIn order to activate passing assistance:
• your vehicle must be following a vehicle ahead (target vehicle)
• your vehicle's
current speed must be
at least 70 km/h (43 mph)
• the set speed
for ACC must be high
enough to safely pass another vehicle.

Automatic braking with AdaptiveCruise Control The Adaptive cruise control (ACC 55
) has a spe-
cial brake function in slow traffic and while sta- tionary.
Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stop- ped at a traffic light, driving will resume automati-cally if the vehicle is stopped for less thanapprox. 3 seconds. If it takes more than 3 sec-onds for the vehicle ahead to begin moving again,Adaptive Cruise Control will go into standbymode and the Auto-hold brake function will acti-vate.
–Adaptive Cruise Control can be reactivated in one of the following ways:
• Pressing the
button on the steering
wheel keypad.
• Pressing the accelerator pedal.
> Adaptive Cruise Control will resume fol- lowing the vehicle ahead if it begins to move within approx. 6 seconds.
NOTE
ACC can keep the vehicle stationary for no more than 5 minutes – after that time theparking brake is applied and Adaptive CruiseControl is deactivated. The parking brake must be released before Adaptive Cruise Control can be reactivated.
Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivated when the vehicle is at a standstill and AdaptiveCruise Control will go into standby mode. Thismeans that the brakes will be released and thevehicle could begin to roll. The driver mustactively apply the brakes to keep the vehicle sta-tionary. This can occur if:
• the driver depresses the brake pedal
• the parking brake is applied
• the gear selector is moved to the
P
, N
or R
positions
• the driver puts Adaptive Cruise Control in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will beapplied to keep the vehicle at a standstill. This occurs if Adaptive Cruise Control is keepingthe vehicle stationary using the brakes and:
• the driver opens the door or unbuckleshis/her seat belt
• ACC has kept the vehicle at a standstill formore than approx. 5 minutes
• the brakes overheat
• the driver switches off the engine manually.
