General notes Hybrid technology combines a fuel efficient

electric motor.
Important safety notes
Danger of electric shock
G DANGER
The vehicle's high-voltage electrical system is
under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
When towing a vehicle after an accident, be sure
to observe the following sections in the vehicle
Operator's Manual: R
Transporting the vehicle R
Towing the vehicle with the rear axle raised R
Towing a vehicle with both axles on the
ground
Read the safety instructions on towing and tow-
starting ( Y
page 53). All components of the hybrid drive system are
marked with yellow warning stickers that warn
you of the danger of high voltage. The cables of
the vehicle's high-voltage electrical system are
orange in color.
The ignition must be switched off when carrying
out general tasks, such as changing bulbs or
checking the coolant level.
Automatic switching off of the hybrid
drive system If components of the restraint system are acti-
vated during an accident, the hybrid drive sys-
tem is automatically deactivated.
The hybrid drive system is not activated when
the vehicle is started if: R
an electrical short circuit is detected in the
hybrid drive system R
an electrical connection in the hybrid drive
system is disconnected
This ensures that you do not come into contact
with high voltage.
Manual switching off of the hybrid drive
system The hybrid drive system can be deactivated
manually using the high voltage switch-off
device.
! To prevent damage to the hybrid drive sys-
tem please observe the following instruc-
tions: R
only deactivate the hybrid drive system
manually in the following situations. R
work on the hybrid drive system may only
be carried out at a qualified specialist work-
shop, even when it has been deactivated
manually.
Deactivate the hybrid system manually if: R
the u restraint system warning lamp in the
instrument cluster lights up after an accident R
the vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated R
the vehicle is badly damaged and has to be
towed or transported10
Hybrid drive system
Safety
Overrun mode In overrun mode, the combustion engine is
switched off and is disconnected from the drive
train. The electric motor: R
generates low thrust, which corresponds to
the overrun mode of an active combustion
engine R
functions as a generator and produces the
necessary energy for the auxiliary consumers
and charges the high-voltage battery
Overrun mode is available in the Comfort drive
program at speeds below 80 mph (130 km/h).
Route-based operating strategy For the route-based operating strategy, the sys-
tem factors in information about the expected
route when route guidance is active.
The information on the route is provided by the
multimedia system and includes the following: R
road categories R
speed limitations
The use of electric energy is automatically opti-
mally distributed from the beginning to the end
of the journey, using information about the
route. The distribution is pre-emptive and takes
into consideration: R
the sections of the journey ahead R
the energy consumption on the whole route The condition of charge of the high-voltage bat-
tery is thus systematically controlled. In addi-
tion, the control function takes into account
that: R
the fuel saving through the use of electrical
energy can vary, dependent on the route (e.g.
urban, interurban or highway) R
the use of electrical energy is held available
for electric driving, particularly for urban
routes
The vehicle thus automatically selects the opti-
mum driving mode for the respective section of
the route.
The route-based operating strategy is available
under the following conditions: R
the Individual drive program is selected R
in the Individual drive program, the ECO set-
ting is selected under Drive R
HYBRID driving mode is selected R
active route guidance is activated R
suitable map data is available
When the route-based operating strategy is
being used, the area in front of the vehicle is
shown as green in the multifunction display.24
Driving
Driving and parking
Urban driving In city traffic, energy is recuperated during fre-
quent deceleration phases.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 80 mph
(130 km/h).
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off ( Y
page 23).
Driving on inter-urban roads The following phases are possible when driving
on inter-urban roads: R
rapid acceleration (boost mode) R
energy recuperation R
electric operation mode
The vehicle can be driven by the electric motor
alone up to a speed of approximately 74 mph
(120 km/ h) .
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving When driving on a highway, switching off the
combustion engine has a particularly positive
effect on fuel consumption and emissions.
If the driver removes his/her foot from the
accelerator pedal in the Comfort drive program
and a speed of 80 mph (130 km/h) is not excee-
ded, the combustion engine is automatically
switched off.
Further information on the automatic engine
switch-off ( Y
page 23).
Refueling
Refueling
General information
Observe the important safety notes under
"Refueling" in the vehicle Operator's Manual. Pressure in the fuel tank must be released
before refueling. Otherwise, the fuel filler flap
cannot be opened.
If you unlock/lock the vehicle from the outside,
the fuel filler flap also unlocks/locks.
The position of the fuel filler cap is displayed in
the instrument cluster
