Drive readiness starts with the
brake pedal pressed when you
press the Start/Stop button.
Pressing the Start/Stop button again switches
drive readiness back off and radio-ready state
is switched back on.
Radio ready state Some electronic systems/power consumers
are ready for operation.
The radio-ready state is switched off automati‐
cally:▷After approx. 8 minutes.▷When the vehicle is locked using the cen‐
tral locking system.▷If the charging state of the batteries is low.
The radio-ready state remains active if, e.g.,
the drive readiness is automatically switched
off for the following reasons:
▷Opening or closing the driver's door.▷Unfastening of the driver's safety belt.▷When automatically switching from low
beams to parking lights.
Radio ready state is switched back on if the
on/off button on the radio is pressed when the
vehicle is parked.
Operating readiness
All electronic systems/power consumers are
ready for operation. Odometer and trip odome‐
ter are displayed in the instrument cluster.
To preserve the battery, use operating readi‐
ness and activated power features only as long
as absolutely necessary.
Operating readiness is switched off:
▷When locking the vehicle, even if the low
beams are activated.▷When opening or closing the driver door, if
the driver's safety belt is unbuckled and
the low beams are turned off.Seite 64ControlsDriving64

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
