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: R
an additional point of resistance in E-MODE
operating mode ( Y
page 226)R
a double pulse in drive program E
( Y
page 229)
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 ( Y
page 226).
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. By this means, in
HYBRID , E-MODE or E-SAVE operating mode
the combustion engine can be switched off and disconnected from the power train (overrun
mode).
The double pulse is available in drive program E
( Y
page 229).
After the accelerator pedal has been released,
the coasting cha racteristi cs of the vehicle are
a
dapted to the traffic conditions.
To avoid 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 D and
braking, the electric motor will operate as a gen-
erator.
Further information on the ECO start/stop func-
tion ( Y
page 231).
Additional driving tips ( Y
page 179).
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: R
entirely by electric propulsion R
in 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.230

Driving an d parking

Overrun mode or braking There are three possible operating modes when
the hybrid vehicle is decelerating: R
energy recovery takes place even when the
vehicle is decelerating purely in overrun mode
( Y
page 225). The electric motor operates as
a generator and stores the recovered energy
in the high-voltage battery R
when the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor This increases the energy recovery tak-
ing place ( Y
page 225) The electric motor
operates as a generator and stores the recov-
ered energy in the high-voltage battery. R
when the brakes are applied with greater
force, the service brakes are also used to slow
the vehicle down. The two systems work
together
Urban driving Energy is recuperated during frequent deceler-
ation and stopping in city traffic.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 120 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 231).
Driving on inter-urban roads The following phases are possible when driving
on inter-urban roads: R
rapid acceleration (boost mode) R
constant energy consumption R
energy recuperation R
electric operation mode
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving
During highway driving, fuel consumption and
emissions are favorably influenced in particular
by reduced power losses.
If the driver removes his foot from the acceler-
ator pedal in drive program E and a speed of
160 km/h is not exceeded, the combustion
engine is automatically switched off.
Further information on the automatic engine
switch-off ( Y
page 231). ECO start/stop function General notes The ECO start/stop function switches the inter-
nal combustion engine off automatically when
the vehicle stops moving and at high speeds
( Y
page 232).
All vehicle systems remain active, e.g. the auto-
matic climate control.
The ECO start/stop function is only available in
drive programs C and E . Electric-only operation
is only possible in drive programs C and E . Addi-
tional information for drive programs
( Y
page 229).
Automatic engine switch-off The engine is switched off automatically, includ-
ing when: R
the driver removes his foot from the acceler-
ator in drive program E and a speed of
160 km/h is not exceeded ( Y
page 232)R
the engine has reached its operating temper-
ature R
the driver’s seat belt is fastened and the
driver’s door is closed R
the driver only slightly depresses the accel-
erator pedal in order to, for example, maintain
the current speed for a limited distance R
the hood is closed and engaged properly R
the high-voltage battery is charged suffi-
ciently R
no malfunctions are present in the hybrid
drive system
The internal combustion engine will not be
switched off automatically, if: R
the self-diagnosis function of the engine con-
trol unit is still active R
there is a malfunction in the hybrid drive sys-
tem R

Tachometer
! Do not drive in the overrevving range, as this
could damage the engine.
The red band in the tachometer indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.
Outside temperature display You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the temperature measured and
does not record the road temperature.
The outside temperature display is in the multi-
function display ( Y
page 237).
Changes in the outside temperature are dis-
played after a short delay.
Coolant temperature display
G WARNING
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.
All vehicles except PLUG-IN HYBRID vehicles:
the coolant temperature display is in the lower
section of the tachometer ( Y
page 36). PLUG-IN HYBRID vehicles: the multifunction dis-
play shows the coolant temperature in the
Coolant submenu ( Y
page 246).
Under normal operating conditions and with the
specified coolant level, the coolant temperature
may rise to 248 ‡ (120 †).

Important safety notes
G WARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for the
country in which you are currently driving when
operating the navigation system.
General notes
Among other things, correct functioning of the
navigation system depends on GPS reception. In
certain situations, GPS reception may be
impaired, there may be interference or there
may be no reception at all, e.g. in tunnels or
parking garages. Audio 20 is equipped with MARGIN ®
MAP PILOT
(see the manufacturer's operating instructions).
The Garmin ®
MAP PILOT operating instructions
are stored on the SD memory card as a PDF file.
The SD card box contains a quick guide.
The following descriptions apply to navigation
with COMAND. Further information can be
found in the Digital Operator's Manual.
