Managing Adaptive Cruise Controlspeed
Adaptive Cruise Control (ACC 45
) can be set to
various speeds.
Setting/changing set speed
Note: This illustration is general and details may vary depending on model and market.
: Increases the set speed.
: Reduces the set speed.
Set speed.
–Change a set speed by pressing the (1)
or
(2) buttons briefly or by pressing and
holding them:
• Press briefly
: Press briefly: each press
changes the speed in +/- 5 mph (+/- 5 km/h) increments.
• Press
and hold: Release the button when
the set speed indicator (3) has moved tothe desired speed.
• The most recently set speed will be stored.
If speed is increased by depressing the accelera- tor pedal while pressing the
button on the
steering wheel, the vehicle's speed when the but- ton is pressed will be stored as the set speed. 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 transmission
Adaptive Cruise Control can follow another vehi- cle at speeds from a standstill up to 200 km/h(125 mph). The lowest speed that can be set for Adaptive Cruise Control is 30 km/h (20 mph). When fol-lowing another vehicle, ACC can monitor thatvehicle's speed and slow your own vehicle down to a standstill, but it is not possible to set speedslower than 30 km/h (20 mph). The highest possible speed that can be set is 200 km/h (125 mph).

296 Select one of the following:
•
Eco - ACC will focus on providing optimal
fuel economy, which will increase the time interval to the vehicle ahead.
•
Comfort - ACC will focus on following the
set time interval to the vehicle ahead as smoothly as possible.
•
Dynamic - ACC will focus on following the
set time interval to the vehicle ahead more exactly, which could mean faster accelerationand heavier braking.
For more information, see "Drive modes". Additional information is provided in the sections "Managing Cruise Control speed" and "ECOdrive mode".

Deactivating/reactivating AdaptiveCruise Control Adaptive Cruise Control (ACC 48
) can be tempo-
rarily put into standby mode and then reactiva- ted.
Deactivating and putting Adaptive Cruise Control in standby mode
Note: This illustration is general and details may vary depending on model.
To temporarily deactivate Adaptive Cruise Control and put it in standby mode:
–Press the button on the steering wheel
(2). > The
symbol in the instrument panel
changes color from WHITE to GRAY and the set speed in the center of the speed-ometer will change from BEIGE to GRAY.
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 49
). 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)
Reactivating Adaptive Cruise Control from standby mode
Note: This illustration is general and details may vary depending on model.
To reactivate ACC from standby mode:
–Press the button on the steering wheel
(1).
> Speed will be set to the most recently stored speed.
WARNING
A noticeable increase in speed may follow when the speed is resumed with the
steering wheel button.

Switching target vehicles withAdaptive Cruise Control
At certain speeds, models with automatic trans- missions and Adaptive Cruise Control (ACC 53
)
can switch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When Adaptive Cruise Control is actively follow- ing another vehicle at speeds under 30 km/h
(20 mph) and switches targets from a moving vehicle to a stationary vehicle, Adaptive CruiseControl will brake for the stationary vehicle.
WARNING
When Adaptive Cruise Control follows another vehicle at speeds over approx. 30 km/h
(20 mph) and changes target vehicle – from a moving vehicle to a stationary one – Adaptive Cruise Control will ignore the stationary vehi-
cle and instead accelerate to the stored speed. • The driver must then intervene and apply the brakes.
Automatic standby mode when switching
targets
Adaptive Cruise Control will be disabled and go into standby mode:
• if your vehicle's speed goes below 5 km/h(3 mph) and Adaptive Cruise Control cannotdetermine if the target object is a stationaryvehicle or another object, e.g. a speed bump.
• if your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatAdaptive Cruise Control no longer has a vehi-cle to follow.

Automatic braking with AdaptiveCruise Control The Adaptive cruise control (ACC 54
) 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.

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 61
.
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.
