Position engaged and ECO assistance acti-
v
ated: automatic brake energy recuperation.
The energy recovery level is selected auto-
matically depending on the navigation data
and traffic situation.
Position engaged: high brake energy recu-
peration
The v
ehicle also performs recuperation when
the brake pedal is pressed.
Eco assistance
The ECO assistance function helps the driver
to use the engine braking effect of the vehi-
cle efficiently. It selects the energy recovery
level depending on the navigation data and
traffic situation.
The ECO assistance function can be switched
on and off in the vehicle settings in the Info-
tainment system.
Driving down hills
When driving down hills, you should drive in
position B if possible.
Never allow the vehicle to roll down moun-
tains or hills in the neutral position N. Troubleshooting
Deactivation of the drive is imminent
The charge level of the high-voltage battery
is too low.
The indicator lamp lights up during v

Adaptive Cruise Control
(ACC)
Introduction to the topic
The Adaptive Cruise Control (ACC) main-
tains a constant speed that you ha
ve set.
If the vehicle approaches a vehicle in
front, the ACC automatically adapts the
speed so that a distance you have selec-
ted is maintained.
Does the vehicle have ACC?
The vehicle is equipped with ACC if you can
adjust settings for ACC in the Assist systems
menu in the Infotainment system.
Speed range
You can set the speed between 20 km/h
(15 mph) and the maximum speed.
Driving with ACC
You can override the active ACC system at
any time. Cruise control will be stopped if you
brake. If you accelerate, cruise control will be
interrupted while you are accelerating and
then resumed.
The intervention by the ACC system is less
dynamic when towing a trailer.
Driver intervention prompt
If automatic deceleration by the ACC
system is not sufficient or the system
limits have been reached, the ACC
system will request you to also brake
by a corresponding message on the
instrument cluster. In addition, the
red warning lamp lights up and an
acoustic warning is given. Take over
control of the vehicle and be prepared
to brake.
Radar sensor
ACC detects driving situations using a radar
sensor at the front of the vehicle. The range of the radar sensor is up to approximately
160 m (
around 520 ft). Special driving situations
Please refer to at the start of the chap-
ter on page 151.
Predictiv
e cruise control system
If the vehicle is equipped with the Dynamic
Road Sign Display function and an Infotain-
ment system with navigation, ACC can pre-
dictively adapt the vehicle speed to detected
speed limits and the course of the road ahead
