–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).

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".

Switching target vehicles withAdaptive Cruise Control
At certain speeds, models with automatic trans- missions and Adaptive Cruise Control (ACC 50
)
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 51
) 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.

3. Pressing the
button on the steering
wheel keypad.
> Cruise Control will start and the vehicle's current speed will be set.
WARNING
Switching from ACC to CC means that the vehicle:
• will no longer maintain a preset time interval to the vehicle ahead.
• will only follow the stored speed and thedriver must therefore apply the brakeswhen necessary.
If CC is active when the engine is turned off, ACC
will be automatically activated the next time theengine is started.

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 58
.
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.
58 Note: This illustration is general and details may vary depending on model.

standby mode:
1. Press the
▶ button on the steering wheel (6).
> The
symbol will change to Pilot
Assist in standby mode (8).
2. Press the
button on the steering wheel
(2).
> Pilot Assist will start and the current speed will be stored, which will be shown by numbers in the center of the speedom-eter.
...or... With Adaptive Cruise Control started:
–Press the ▶ button on the steering wheel (6).
> 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 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.

Setting a time interval for PilotAssist
Pilot Assist can be set to different time intervals.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The more bars, the longerthe time interval. One bar rep-resents an interval of
approx. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
NOTE
When the symbol in the instrument panel shows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval. When only a steering wheel is shown, there is no vehicle ahead within a reasonable dis-tance.
