Driving in detail: eDRIVE
Hints Awareness of vehicle reduced when
driven in electric mode
When driving in electric mode, note that, due
to the lack of engine noise, pedestrians and
other traffic might pay less attention to the ve‐
hicle due to missing engine noises. Please
take special care when parking or leaving a
parking space.◀
Cautiously remove your foot from the ac‐
celerator pedal
Cautiously remove your foot from the acceler‐
ator pedal because the braking effect of the
electric motor can be stronger than with a
combustion engine. Otherwise, abrupt braking
and slow-down may confuse other traffic.◀
Accelerator pedal positions1Deceleration2Coasting3Acceleration or constant speed: ePOWER
Deceleration
The deceleration depends on the position of
the accelerator pedal. The less the actuation of
the accelerator pedal, the greater the decelera‐
tion. In this way energy is recovered and the
high-voltage battery is charged.
Releasing the accelerator pedal causes decel‐
eration similar to cautious braking. Addition‐
ally, the brake lights will come on without hit‐
ting the brakes.
Energy recovery: CHARGE The high-voltage battery is recharged in part
through energy recovery. The electric motor
acts as a generator when decelerating and
converts the kinetic energy into electrical en‐
ergy.
Energy can be recovered if the following condi‐
tions are met:▷The vehicle is moving.▷Speed higher than approx.
12 mph/20 km/h.▷Selector lever position D or R is set.▷Gas pedal is not actuated or only pressed
down 1/3 of the way.
Energy cannot be recovered in the following
situations:
▷Selector lever position N is set.▷While drive stability control systems, e.g.
DTC, are active and control the vehicle,
even though this is not indicated by an in‐
dicator light.▷The high-voltage battery is fully charged.▷When temperature of the high-voltage bat‐
tery is very low or very high.
In winter it might be possible that the en‐
ergy recovery is temporarily unavailable af‐
ter startup.
Always be ready to apply the brake
Always be ready to apply the brake, be‐
cause without energy recovery there is also no
braking action through the electric drive unit.
The vehicle could roll further than anticipated.
This may constitute a danger for other traffic.◀
Exemplary traffic situations
If a deceleration operation is foreseeable while
driving, this can be used for energy recovery.
Seite 68ControlsDriving68
Online Edition for Part no. 01 40 2 960 865 - II/15

The following exemplary driving situations may
show that:▷Decelerating downhill.▷Deceleration before a red light.
Avoid late or abrupt braking. Instead, deceler‐
ate the vehicle using energy recovery.
Coasting
The electric drive makes it possible to roll with‐
out consuming energy. This driving condition
is referred to as coasting.
Proactive driving reduces energy consumption
and increases the range.
With vehicle rolling, no energy is recovered.
Exemplary traffic situations If a route can be traveled without anticipated
need for braking, it is advantageous to roll.
The following exemplary driving situations may
show that:
▷Rolling on a straight downhill route without
obstacles.▷Coasting on a route without obstacles.
Avoid late or abrupt braking.
Range Extender
Increase range
If the charging state of the high-voltage battery
drops during travel to a minimum value, the
Range Extender starts and supplies the re‐
quired electrical energy for driving on.
The symbol on the charging state indicator
designates a Range Extender reel-on time.
The Range Extender controls its output auto‐
matically, turns itself off and restarts according
to the driving situation.
The high-voltage battery will not be charged
by the Range Extender.
Automatic maintenance run
To ensure that the Range Extender functions
properly even during longer periods of non-
use, the Range Extender is automatically acti‐
vated for a few minutes at certain intervals dur‐
ing the trip. Respective Check Control
messages indicate the dry run. Should that oc‐
cur at an unfavorable time you may cancel the
dry run by pressing the Start/Stop button. It
postpones the dry run.
Should the high-voltage battery be fully
charged or if there is not enough gas in the
tank then a dry run will not be executed.
Heavily discharged high-voltage
battery
If the high-voltage battery is heavily dis‐
charged during the trip, the performance and
some comfort features are reduced step-by-
step to extend the range.
Heated high-voltage battery
With a stationary dirt In exceptional cases, it is possible that the
high-voltage battery heats up sharply when the
vehicle is stationary. E. g. with extreme exter‐
nal temperatures and direct solar radiation.
With a overheated high-voltage battery, drive
readiness cannot be switched on.
A Check Control message is displayed.
Another message will indicate when drive
readiness is available again.
While driving
If the high-voltage battery overheats during the
trip, the performance is reduced step-by-step
in order to cool down the battery. The ePO‐
WER performance display in the instrument
cluster returns in the process. When tempera‐
ture increases further, park the vehicle until the
high-voltage batter has cooled down. Should
the performance display fall to 0, drive readi‐Seite 69DrivingControls69

High-voltage battery charge indicator
High voltage
Even if no fill level bars are displayed next
to the battery symbol, the high-voltage system
is still under high voltage.◀
The fill level bars indicate the available charg‐
ing state of the high-voltage battery when op‐
erating readiness and drive readiness are
switched on.
With a low range the color of the charging sta‐
tus indicator switches from blue to yellow.
In addition, the range for electric driving is dis‐
played.
With Range Extender: maintaining charging state
The arrow on the charging state indicator
designates the Range Extender reel-on time. If
Range Extender is activated, the current
charging state of the high-voltage battery is
maintained.
▷Gray arrow: Range Extender deactivated.▷White arrow: Range Extender activated.Performance display
The accelerator pedal indicator in the perform‐
ance display indicates the current efficiency of
the driving style. The efficient range of the per‐
formance display is colored blue.

Check Control
The concept The Check Control system monitors functions
in the vehicle and notifies you of malfunctions
in the monitored systems.
A Check Control message is displayed as a
combination of indicator or warning lights and
text messages in the instrument cluster.
In addition, an acoustic signal may sound and atext message may appear on the Control Dis‐
play.
Indicator/warning lights
General information
The indicator and warning lights in the instru‐
ment cluster can light up in a variety of combi‐
nations and colors.
Several lights indicate function checks and
light up only temporarily when drive readiness
or operating readiness are activated.
Red lights Safety belt reminder Flashing or illuminated: safety belt on
the driver or passenger side is not
buckled. The safety belt reminder can
also be activated if objects are placed on the
front passenger seat.
Make sure that the safety belts are positioned
correctly.
