Haptic accelerator pedal General notes
The haptic accelerator pedal helps you to
reduce the fuel consumption and emissions
of your vehicle.
There are two different functions available for
this purpose:
R an additional point of resistance in E-MODE
operating mode (Y page 290)
R a double pulse in drive program E
(Y page 295)
Additional point of resistance in the hap-
tic accelerator pedal
The maximum available electric performance
is indicated by a tangible point of resistance
in the haptic accelerator pedal.
The additional point of resistance is available in E-MODE operating mode (Y page 290).
If you depress the haptic accelerator pedal
beyond the pressure point, the combustion
engine is switched on.
Double pulses in the haptic accelerator
pedal
A noticeable double pulse in the haptic accel-
erator pedal is a recommendation that you
should release the accelerator pedal. By this
means, in HYBRID,E-MODE orE-SAVE oper-
ating mode the combustion engine can be switched off and disconnected from the
power train (overrun mode).
The double pulse is available in drive program
E (Y page 295).
After the accelerator pedal has been
released, the coasting characteristics of the
vehicle are adapted to the traffic conditions
To avoid getting too close to the vehicle in
front, you must apply the brakes manually
when necessary.
Driving tips General driving tips
Drive carefully and maintain a suitable dis-
tance from the vehicle in front. Avoid frequent
and sudden acceleration as well as abrupt
braking.
During partial electric drive, pulling away and acceleration, the electric motor supports the internal combustion engine.
During overrun in transmission position Dand
braking, the electric motor operates as an
alternator.
Further information on the ECO start/stop
function (Y page 298).
Additional driving tips (Y page 222).
Stationary vehicle
If the vehicle is stopped, the combustion
engine is, for the most part, switched off.
Automatic climate control continues to func-
tion. The electro-mechanically assisted steer-
ing gear allows use of the power steering
without loss of comfort.
Acceleration
Depending on the operating mode, pulling
away and driving under low load conditions
are performed:
R entirely by electric propulsion
R in combination with the internal combus-
tion engine
When accelerating at an increased or full
load, boost mode is utilised. The electric
motor supports the internal combustion PLUG‑IN HYBRID operation

Uncoupling a trailer
G
WARNING
If you uncouple a trailer with an engaged over- run brake, you could trap your hand between
the vehicle and the trailer drawbar. This poses a risk of injury.
Do not uncouple a trailer with an engaged
overrun brake. G
WARNING
Vehicles with level control:
If you disconnect the trailer cable, the vehicle is lowered. This can cause you or others to
become trapped between the vehicle body
and tyres, or underneath the vehicle. This
poses a risk of injury.
Make sure that no-one is in the immediate
vicinity of the wheel arch or underneath the
vehicle when disconnecting the trailer cable.
! Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound- ing of the overrun brake.
! Remove the installed adapter cable
before folding in the ball coupling. Other-
wise, damage may occur to the rear
bumper and the adapter cable.
X Make sure that the transmission is in posi-
tion P.
X Apply the electric parking brake.
X Secure the trailer against rolling away.
X Remove the trailer cable and decouple the
trailer. Swinging the ball coupling in
! Do not attempt to speed the up the swing-
out procedure by applying additional pres-
sure with your foot. The system could oth-
erwise be mechanically damaged.
Swing the ball coupling back in using the
switch on the driver's door or tailgate, if you
are not using the trailer tow hitch. Only release the ball coupling when its range
of movement is unobstructed. Folding in using the switch in the driver's
door (all vehicles except plug-in hybrid
vehicles):
X Make sure that the vehicle is stationary and
the trailer cables are disconnected.
X Place the protective covering on the ball
coupling.
X Shift the transmission to position P.
X Switch the ignition on.
X Pull switch :briefly.
After a short time the ball coupling swings
