high-voltage batter has cooled down. Should
the performance display fall to 0, drive readi‐
ness is switched off and the vehicle comes to a
stop.
Parking brake The conceptThe parking brake is used to prevent the vehi‐
cle from rolling when it is parked.
Setting
Apply parking brake and further secure
the vehicle if needed.
Set the parking brake firmly when parking; oth‐
erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the ve‐
hicle, e.g., by turning the steering wheel in the
direction of the curb.◀
Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, e.g., can‐
not release the parking brake.◀
Pull the reel.
The LED lights up.
The indicator lamp lights up red. The
parking brake is set.
While driving
Use as emergency brake while driving:
Pull the reel and hold it. The vehicle brakes
hard while the reel is being pulled.
The indicator lamp lights up red, a sig‐
nal sounds and the brake lights light
up.
A Check Control message is displayed.
If the vehicle is slowed down down to a speed
of approx. 2 mph/3 km/h the parking brake is
set.
Releasing
With drive readiness switched on:
Press the reel while stepping on the
brake pedal or selector lever position P is
set.
The LED and indicator lamp go out.
The parking brake is released.
Automatic release For automatic release, step on the accelerator
pedal.
The LED and indicator lamp go out.
The parking brake is automatically released
when you step on the accelerator:▷Drive readiness switched on.▷Drive mode engaged.▷Driver buckled in and doors closed.
Inadvertent operation of the accelerator
pedal
Make sure that the accelerator pedal is not op‐
erated unintentionally; otherwise, the vehicle is
set in motion and there is a risk of an acci‐
dent.◀
Malfunction In the event of a failure or malfunction of the
parking brake, secure the vehicle against roll‐
ing using a wheel chock, e.g., when leaving it.
Seite 66ControlsDriving68
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.
Turn signal, high beams,
headlight flasher
Turn signal
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.

DisplaysVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are notnecessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Instrument cluster
The concept
The instrument cluster is a variable display.
Some of the displays in the instrument clustermay differ from the way they are shown in this
Owner's Handbook.

Displays in the instrument cluster
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
High-voltage battery charge indicator
High voltage
Even if no bars are displayed in the bat‐
tery 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.Manual activating/deactivating the Maintaining
charging state function.
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.
Accelerator pedal indicator in the CHARGE
range, arrow 1: display for energy recovered by
coasting or when decelerating.
Accelerator pedal indicator in the ePOWER
range, arrow 2: display when accelerating.
Use eDRIVE efficiently, refer to page 144.
Drive readiness: READY The READY display indicates
that the vehicle is ready for driv‐
ing. Drive readiness in detail, re‐
fer to page 63.

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
Seite 75DisplaysControls77
also be activated if objects are placed on the
front passenger seat.

ger of a collision or the distance to the
vehicle ahead is too small.
Increase distance.
Flashing: acute warning of the imminent dan‐
ger of a collision when the vehicle approaches
another vehicle at a relatively high differential
speed.
Intervention by braking or make an evasive ma‐
neuver.Pedestrian warning
If a collision with a person detected in
this way is imminent, the symbol lights
up and a signal sounds.

sible. Braking force boost in some
cases defective. Stop carefully. Take
into account longer brake travel. Have this
checked by the service center immediately.
DSC Dynamic Stability Control Flashing: DSC controls the drive and
braking forces. The vehicle is stabi‐
lized. Reduce speed and adapt driving
profile to the driving circumstances.Seite 76ControlsDisplays78
Illuminated: DSC failed. Have the system
checked by the service center.

tiously. Avoid sudden braking and steering ma‐
neuvers.
For more information, see Flat Tire Monitor, re‐
fer to page 98.
Tire Pressure Monitor TPM Illuminated: the Tire Pressure Monitor
signals a loss of tire inflation pressure
in a tire.

detected.▷Interference through systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.▷RDC could not conclude the reset: perform
the reset of the system again.▷A wheel without TPM electronics is fitted:
