Drive readiness
If drive readiness is switched on, the vehicle
ready to drive and the READY signal, refer to
page 63, is displayed in the instrument clus‐
ter.
All vehicle systems are ready for operation.
Most of the indicator and warning lights in the
instrument cluster light up for a varied length
of time.
Activated drive readiness is the equivalent of a
running engine in conventional vehicles. Deac‐
tivated engine readiness is equivalent to
switching the ignition off.
To save battery power when parking, reel off
drive readiness and any unnecessary elec‐
tronic systems/power consumers.
Drive readiness is switched off automatically:
▷When opening or closing the driver door, if
the driver's safety belt is unbuckled.
Note
If drive readiness is switched on, the system
automatically switches to the radio-ready state
when the door is opened and the driver's
safety belt is unbuckled, or if the lights are
turned off or the daytime running lights are ac‐
tivated.

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

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.

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.

Braking intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Premise for the brake boos‐
ter is sufficiently quick and hard stepping on
the brake pedal. The system can assist with
some braking intervention if there is risk of a
collision. At low speeds vehicles may thus
come to a complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
Tow-starting and towing
For towing the vehicle turn, switch off the
Intelligent Safety systems; otherwise malfunc‐
tions of the individual braking systems might
lead to accidents.◀
System limits Be alert
Due to system limitations, warnings may
be not issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the risk
of an accident.◀
Detection range
The system's detection potential is limited.
Thus a warning might not be issued or be is‐
sued late.
E. g. the following situations may not be de‐
tected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you, or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
deactivated, e.g. DSC OFF.▷If the field of view of the camera in the mir‐
ror is dirty or obscured.▷Up to 10 seconds after drive readiness is
established.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is constant blinding effects be‐
cause of oncoming light, e.g., from the sun
low in the sky.
Warning sensitivity
The more sensitive the warning settings are,
the more warnings are displayed. However,
there may also be an excess of false warnings.
Pedestrian warning with city
braking function
The concept
The ystem can help prevent accidents with pe‐
destrians.
The system issues a warning in the city driving
speed area if there is imminent danger of a col‐
lision with pedestrians and includes a braking
function.
