Exemplary traffic situations
If a deceleration operation is foreseeable while
driving, this can be used for energy recovery.
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, READY is displayed in the
instrument cluster. With vehicle rolling, no en‐
ergy 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 batteryWith 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 theSeite 65DrivingControls67
After a power failure
Putting the parking brake into
operation1.Switch on the ignition.2. Press the reel while stepping on the
brake pedal or selector lever position P is
set.
It may take several seconds for the brake to be
put into operation. Any sounds associated with
this are normal.
The indicator lamp in the instrument
cluster goes out as soon as the parking
brake is ready for operation.
Hold function The concept
The system holds the vehicle automatically
when gear is engaged. This prevents rolling
against the direction of travel.
In selector lever position D, the vehicle cannot
roll backwards. In selector lever position R, it
cannot roll forward. The brake pedal does not
have to be pressed.
Hints
To reduce energy consumption when the hold
function is activated, activate the parking brake
or engage lever in position P P when the vehi‐
cle is stopped for long periods of time.
The hold function can be by the vehicle's load
and the road incline. If needed a Check Control
message will appear and position P will be se‐
lected automatically.

Hints Do not adjust the exterior mirrors
Do not adjust the exterior mirror while
driving and when blinker/hazards are on, or
else the additional blinker lights in the exterior
mirror are out of position and can't be seen.◀
Using turn signals
Press the lever beyond the resistance point.
To reel off manually, press the lever to the re‐
sistance point.
Unusually rapid flashing of the indicator lamp
indicates that a turn signal bulb has failed.
Triple turn signal activation Press the lever to the resistance point.
The turn signal flashes three times.
The function can be activated or deactivated.

The concept The display depends on the system's operat‐
ing condition. The following functions of the
eDRIVE system are shown in the instrument
cluster:▷High-voltage battery charge indicator.▷Electric driving: ePOWER.▷Energy recovery: CHARGE.▷Drive readiness: READY.Seite 73DisplaysControls75
The top bars indicate the average energy con‐
sumed while driving time, arrow 1. The lower
bars indicate the average energy recovered
while driving time, arrow 2.
One bar indicates one minute.
The eDRIVE system's average fuel consump‐
tion is indicated by a line above the bar display
and as a value on the right next to the graph.

Ice on roads
Even at temperatures above
+37 ℉/+3 ℃, roads might be icy.
Therefore, drive carefully on bridges and
shaded roads, e.g., to avoid the increased risk
of an accident.◀
Time
The time is displayed in the computer.
Setting the time and time format, refer to
page 87.
Range
The expected range for the energy stored in
the high-voltage battery is displayed on the
right side of the instrument cluster next to the
charging state indicator of the high-voltage
battery.
With Range Extender:
The range of the Range Extender is displayed
separately next to the fuel gauge. The total
range can be displayed via the on-board com‐
puter. Expanding the range with Range Ex‐
tender, refer to page 67.
Two Check Control messages indicate a lim‐
ited range.
The range display is dynamic.
The range can be abruptly reduced or in‐
creased based on the following factors:▷Driving style.▷Traffic conditions.▷Program change via Driving Dynamics
Control.▷Climate and terrain conditions.▷Automatic climate control settings.▷After determination of a route by the navi‐
gation system.▷When exiting a route or recalculating a
route.Hints
Observe range
Always make sure that the range is suffi‐
cient for the planned trip. The range is dynamic
and can abruptly change.◀
Increase range, refer to page 144.
