Overrun mode
In overrun mode, the combustion engine is
switched off and is disconnected from the drive
train. The electric motor:
Rgenerates low thrust, which corresponds to
the overrun mode of an active combustion
engine
Rfunctions as a generator and produces the
necessary energy for the auxiliary consumersand charges the high-voltage battery
Overrun mode is available in the Comfortdrive
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:
Rroad categories
Rspeed 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:
Rthe sections of the journey ahead
Rthe 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:
Rthe fuel saving through the use of electrical
energy can vary, dependent on the route (e.g.
urban, interurban or highway)
Rthe 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:
Rthe Individual drive program is selected
Rin theIndividual drive program, the ECO set-
ting is selected under Drive
RHYBRID driving mode is selected
Ractive route guidance is activated
Rsuitable 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.
24Driving
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 (
Ypage 23).
Driving on inter-urban roads
The following phases are possible when driving
on inter-urban roads:
Rrapid acceleration (boost mode)
Renergy recuperation
Relectric 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 Comfortdrive 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 (
Ypage 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
8. The arrow next to
the filling pump indicates the side of the vehicle.

GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
!A display message is shown if the coolant
temperature is too high.
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The engine
will otherwise be damaged.
The multifunction display shows the coolant
temperature in the Coolant
submenu.
Under normal operating conditions and with the
specified coolant level, the coolant temperature
may rise to 248 ‡ (120 †).
