XIf possible, move the vehicle out of the
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-
tion P.
Apply the electric parking brake.
Safeguard the vehicle against rolling away
(see the vehicle Operator's Manual).
XTo use the high-voltage switch-off device:
open the tailgate.
XLift the cargo compartment floor upwards
(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.
XPull high-voltage switch-off device ;apart
until it engages.
If the hybrid drive system has been deactivated
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.
Charging the high-voltage battery (
Ypage 29).
Engine compartment
Before opening the hood:
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).
XObserve the warning notes on the hood (see
the vehicle Operator's Manual).
RBS driving safety system (Recupera-
tive Brake System)
The Recuperative Brake System supports you
when braking with an electronically-controlled
brake boost mode and enables the recovery of
kinetic energy (recuperation).

Braking System (

General notes
Hybrid technolog ycombine s afuelefficien t

electric motor. In HYBRIDmode, thehybrid
drive syste mautomatically selects th emost effi-
cien toperatin gmode fo revery drivin gsituation .
Drive th evehicle in th eusual manner.
To sav efue lin HYBRID mode, thehybrid drive
syste mswitches of fth ecombustion engin eas
ofte nas possible durin gth ejourney when powe r
output requirements are low. Whe npowe rout -
put requirements are low, th eelectric moto r
powers th evehicle. The engin eis switched on ,
eve nwhil eth evehicle is in motion ,when a
higher powe routput is required. The engin eis
usually switched of fwhen th evehicle is station -
ary. Consequently, there is usually no engin e
idlin gas wit hcombustion engin evehicles .
Fo rpulling away and accelerating, th eelectric
moto rsupports th einternal combustion engin e

tery. In addition ,th epowe ris used fo relectric
driving, operation of th eelectric refrigerant
compressor and to supply th e12 Von-boar d

Vehicles wit han electric moto rgenerate muc h

situations.

a speed of over 20 mph (30 km/h)the sound is
switched off. Above this speed, the natural
sounds from the vehicle are sufficient that it can
be heard in good time by other road users.
20Driving
Dr iving an d parking
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.
Drive programs
DYNAMIC SELECT controller
Select the drive program using the DYNAMIC
SELECT controller. Depending on the drive pro-
gram selected the following vehicle character-
istics will change:
Rthe drive (engine and transmission manage-
ment)
Rthe suspension
Rthe steering.
Rthe energy management
Each time you start the engine with the ignition SmartKey or the Start/Stop button, the Com-
fort drive program is activated. You can find
further information on starting the engine in the
vehicle Operator's Manual.
XTurn DYNAMIC SELECT controller :as many
times as necessary until the desired drive
program is selected.
The status icon of the selected drive program
is shown in the multifunction display.
In addition, the current drive program settings are displayed briefly in the multimedia system
display.
