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 280)
R a double impulse in E+operating mode
(Y page 285) 286
PLUG-IN HYBRID operationDriving and parking

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 280)
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 tangible double pulse in the haptic acceler- ator pedal gives you a recommendation to
release the accelerator pedal. By this means, in HYBRID, E-MODEorE-SAVE operating
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+ (Ypage 285).
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 safe distance
from the vehicle in front. Avoid frequent and
sudden acceleration as well as abrupt brak-
ing.
During partial electric driving, pulling away
and acceleration, the electric motor supports
the internal combustion engine.
During overrun in transmission position Dand
braking, the electric motor will operate as a
generator.
Further information on the ECO start/stop
function (Y page 288).
Additional driving tips (Y page 224).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 electromechanically assisted steer-
ing gear allows you to use the power steering
without reduced 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 utilized. The electric
motor supports the internal combustion
engine by providing additional torque when
the accelerator is depressed rapidly.
Overrun mode or braking
There are three possible operating modes
when the hybrid vehicle is decelerating:
R energy recovery takes place even when the
vehicle is decelerating purely in overrun
mode (Y page 276). The electric motor
operates as a generator and stores the
recovered energy in the high-voltage bat-
tery.
R when the brakes are applied lightly, the
vehicle is slowed down further by the elec-
tric motor. This increases the energy recov- ery taking place (Y page 276). The electric
motor operates as a generator and stores
the recovered energy in the high-voltage
battery.
R when the brakes are applied with greater
force, the service brakes are also used to
slow the vehicle down. The two systems
work together.
Urban driving
Energy is recuperated during frequent decel-
eration and stopping in city traffic. PLUG-IN HYBRID operation

you first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic sys-
tem may be damaged.
R the transmission is locked in position P
after disconnecting the battery. The vehi-
cle is secured against rolling away. You
can then no longer move the vehicle.
The batteries and the covers of the positive
terminal clamps must always be installed
securely during operation.
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion.
Fire, open flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks. Electrolyte or battery acid is corro-
sive. Avoid contact with skin, eyes
or clothing.
Wear suitable protective clothing,
especially gloves, apron and face-
guard.
Immediately rinse electrolyte or
acid splashes off with clean water. Contact a physician if necessary. Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehi- cle occupants from suffering acid burns
should the battery be damaged in the event of
an accident.
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the
vehicle. In this case, have the battery discon- nected at a qualified specialist workshop. You
can also charge the battery with a charger
recommended by Mercedes-Benz. Contact a
qualified specialist workshop for further infor- mation.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly
for short trips or if you leave it standing idle
for a lengthy period. Consult a qualified spe-
cialist workshop if you wish to leave your
vehicle parked for a long period of time.
i Remove the SmartKey if you park the
vehicle and do not require any electrical
consumers. The vehicle will then use very
little energy, thus conserving battery
power.
i Hybrid vehicles:
if the battery condition
of charge is sufficient, the high-voltage bat- tery can also supply the 12 V battery with
energy. This only happens if the condition
of charge of the 12 V battery requires this,
e.g. after using electrical consumers for an extended period with the engine switched
off. As the on-board voltage is continuously
monitored this can also be performed when the engine is switched off. The condition of
charge of the 12 V battery and the on-board
voltage are thereby kept stable for a longer period. High-voltage battery – important

voltage battery. Battery (vehicle)
