danger zone:shift the automatic transmis-
sion into position N.
XRelease the electric parking brake.
XRoll the vehicle to a safe place and park it
safely.
Get assistance from others if necessary.
The vehicle is locked automatically when the
ignition is switched on and the wheels are turn-
ing. There is therefore a risk of being locked out
if the vehicle is being pushed or tested on a
dynamometer.
XSwitch the ignition off.
XShift the automatic transmission to park posi-

XTo use the high-voltage switch-off device:
open the tailgate.

(see the vehicle Operator's Manual).
XPull off the right-hand paneling in the cargo
compartment.
XPress release clip :in the direction of the
arrow and pull it out.

due to reasons mentioned above, have it
checked at a qualified specialist workshop
before reactivation.
High-voltage battery
GWARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements.
GWARNING
If the housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. These are poisonous and caustic.
There is a risk of injury.
Avoid contact with skin, eyes or clothing.
Immediately rinse electrolyte splashes off
with water and seek medical attention
straight away.
!Exhaustive discharge caused by the vehicle
standing idle for lengthy periods can damage
the high-voltage battery. If the vehicle is idle
for lengthy periods leave the high-voltage bat-
tery connected to a charging station.

XApply the electric parking brake.
XShift the transmission to position P.
XSwitch the ignition off.
XObserve the warning notes on the risk of elec-
tric shock (Ypage 10).

The Recuperative Brake System supports you
when braking with an electronically-controlled
brake boost mode and enables the recovery of
kinetic energy (recuperation).

Safety
Z
If manual gearshifting is deactivated, the auto-
matic transmission shifts:
Rinto the drive program that was last selected,
and
Rinto the driving mode that was last selected
If you change the drive program, the operating
mode that was last selected is stored for approx-
imately 60 seconds. After this time, the HYBRID
operating mode is automatically activated.
Starting the engine
The vehicle starts in electric mode without the
internal combustion engine (noiseless start).
The internal combustion engine starts only after the power demanded by the driver exceeds the
available power that the electric motor can cur-
rently provide.
Noiseless start operation is dependent on the
outside temperature and the operating temper- ature of the internal combustion engine. If not all
conditions for noiseless start operation are ful-
filled, the vehicle starts with the internal com-
bustion engine.
Observe the notes on starting in the vehicle
Operator's Manual.
XSwitch on the ignition.
XDepress the brake pedal.
XStart the vehicle (see the vehicle Operator's
Manual).
When the vehicle is operational, the READY
indicator lights up in the multifunction display
(
Ypage 39).
Pulling away
XDepress the brake pedal and keep it
depressed.
XShift the transmission to position Dor R.
XIf the Apply Brake to Shift from 'P'display message appears in the multifunction display, depress the brake pedal more firmly
and select the desired transmission position.
XRelease the brake pedal.
XCarefully depress the accelerator pedal.
You can find further information on pulling away
in the vehicle Operator's Manual.

General notes
The ECO start/stop function switches the com-
bustion engine off automatically when the veh i-
cle stops moving and at speeds below 80 mph
(13 0km/ h)(

ing when:
Rthe driver removes his/her foot from the

erator pedal in order to, for example, maintain
the current speed for a limited distance
Rthe hood is closed and engaged properly
Rthe high-voltage battery is charged suffi-
ciently
Rno malfunctions are present in the hybrid
drive system

tion engine starts automatically in certain situa-
tions, if:

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 23).
You can find further driving tips in the vehicle
Operator's Manual.
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 rapidly under increased or
full load, increased boost mode is utilized. The
electric motor supports the combustion engine
by providing additional drive torque.
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 20). The electric motor operates as a
generator and stores the recovered energy in
the high-voltage battery
Rwhen the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor. This increases the energy recovery
taking place (
Ypage 20). The electric motor
operates as a generator and stores the recov-
ered energy in the high-voltage battery
Rduring heavy braking, the service brake is also
used to slow down the vehicle. The two sys-
tems work together
