Power meter
The power meter supports you in electric mode
and displays the output obtained.
If you select the E-MODEoperating mode, the
instrument cluster will display the power meter
instead of the tachometer.
iThe tachometer appears again if:
Ryou select HYBRID,E-SAVE orCHARGE
Rthe current state of charge of the high-volt-
age battery is too low to drive the vehicle in
the E-MODE electrical operating mode
The power meter is divided into the following
areas:
RLimit:(OFF):
If the needle reaches limit :, the electric
motor and the combustion engine are
switched off.
RArea ;to? (CHARGE):
This shows the recuperated energy which is
stored in the high-voltage battery as electrical energy.
The more recuperated energy the high-volt-
age battery has, the further needle ?travels
in direction =. When the needle reaches limit
=, the maximum amount of recuperative
braking power has been reached.
In addition to the recuperative braking power,
the mechanical brakes are activated in the
area between ;and =.
ROutput range of electric motor: ?toA:
The electric output of the electric motor is
displayed here. When the power meter needle
reaches position ?, the electric motor is
operational. With increasing pressure on the
accelerator pedal, the needle moves towards
A.
The output limit of the electric motor Acan
be felt via the additional pressure point in the
haptic accelerator pedal.
If you do not press the haptic accelerator
pedal beyond the pressure point, you can
control electric operation, at low speeds, to
only drive in electric mode.
ROutput range of combustion engine: AtoB:
The output of the combustion engine and the
electric motor is displayed here. When the
power meter needle reaches position Aand
you press the haptic ac
celerator pedal
beyond the pressure point, then the combus-
tion engine is switched on.

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:
Ran additional point of resistance in E-MODE
operating mode (Ypage 243)
Ra double impulse in E+operating mode
(Ypage 250)
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 (
Ypage 243).
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 accelerator
pedal gives you a recommendation to release
the accelerator pedal. The combustion engine
can switch off and be disconnected from the
drive train (overrun mode).
The double pulse is available in drive program E+
(
Ypage 250). After the accelerator pedal has been released,
the coasting characteristics of the vehicle are
adapted to the traffic conditions.
To
avo
id getting too close to the vehicle in front,
you must apply the brakes manually when nec-
essary.
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 braking.
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 gen-
erator.
Further information on the ECO start/stop func-
tion (
Ypage 252).
Additional driving tips (
Ypage 192).
Stationary vehicle
If the vehicle is stopped, the combustion engine
is, for the most part, switched off. Automatic
climate control continues to function. The elec-
tromechanically assisted steering 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 per-
formed:
Rentirely by electric propulsion
Rin combination with the internal combustion
engine
When accelerating at an increased or full load,
boost mode is utilized. The electric motor sup-
ports the internal combustion engine by provid-
ing additional torque when the accelerator is
depressed rapidly.
Overrun mode or braking
There are three possible operating modes when
the hybrid vehicle is decelerating:
Renergy recovery takes place even when the
vehicle is decelerating purely in overrun mode
(
Ypage 240). The electric motor operates as

HEnvironmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
!Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Mainte-
nance Booklet or contact a qualified specialist
workshop for more information.
!Always have work on batteries carried out at
a qualified specialist workshop. Should it, in
exceptional circumstances, be absolutely
necessary to disconnect the 12-volt battery
yourself, observe the following:
Rsecure the vehicle to prevent it from rolling
away.
Rswitch off the ignition.
Ralways disconnect the negative terminal
clamp first, followed by the positive termi-
nal clamp.
After the battery has been disconnected, the
transmission is locked in position P.
After the work has been done, install the bat-
tery and replace the cover of the positive ter-
minal clamp firmly.
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. Con-
tact 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 vehicle
occupants from suffering acid burns should the
battery be damaged in the event of an accident.
In order for the battery to achieve the maximum
possible service life, it must always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.
In this case, have the battery disconnected at a
qualified specialist workshop. You can also
charge the battery with a charger recommended
by Mercedes-Benz. Contact a qualified special-
ist workshop for further information.
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 specialist
workshop if you wish to leave your vehicle
parked for a long period of time.
