Open trunk lid with no-touch activation
With Comfort Access, the trunk lid can be
opened with no-touch activation using the re‐
mote control you are carrying.
A sensor detects a directed foot motion in the
center of the area at the rear of the car and the
trunk lid opens.
During opening, the trunk lid pivots back and up.
Ensure that adequate clearance is available be‐
fore opening.
Do not touch vehicle
With the foot motion, make sure there is
steady stance and do not touch the vehicle; oth‐
erwise, there is a danger of injury, e. g. from hot
exhaust system parts.◀1.Position in the center behind the vehicle.2.Move foot in the direction of travel under‐
neath the bumper and immediately back.
The trunk lid opens, regardless of whether it was
previously locked or unlocked.
Preventing inadvertent opening
In situations where the trunk lid should is
not to be opened with no-touch activation, en‐
sure that the remote control is located beyond
the range of the sensor, at least 5 ft/1.50 m from
the rear of the car.
Otherwise, the trunk lid may be opened inad‐
vertently, for example by an unintentional or
misinterpreted movement of the foot.◀

Alarm system
The concept
The vehicle alarm system responds to:▷Opening of a door, the hood or the trunk lid.▷Movements in the vehicle.▷Changes in the vehicle tilt, e.g., during at‐
tempts to steal a wheel or when towing the
car.▷Interruptions in battery voltage.
The alarm system briefly indicates tampering:
▷By sounding an acoustic alarm.▷By switching on the hazard warning system.▷By flashing the high beams.
Arming and disarming the alarm
system
General information
When you lock or unlock the vehicle, either with
the remote control, Comfort Access or at the
door lock the alarm system is armed or disarmed
at the same time.
Door lock and armed alarm system
Unlocking via the door lock will trigger the alarm
on some country-specific versions.
In order to terminate this alarm, unlock vehicle
with the remote control or switch on the ignition,
if necessary, by emergency detection of the re‐
mote control.
Trunk lid and armed alarm system
The trunk lid can be opened using the remote
control, even if the alarm system is armed.
Press the button on the remote control
for approx. 1 second.
After the trunk lid is closed, it is locked and
monitored again by the alarm system. The haz‐
ard warning system flashes once.
In some vehicle equipment variants, the trunk lid
can only be opened using the remote control if
the vehicle was unlocked first.
Panic mode Press the button on the remote control
for at least 3 seconds.
Switching off the alarm▷Unlock the vehicle using the remote control.▷With Comfort Access: if you are carrying the
remote control with you, pull on the door
handle.

The window closes automatically.
Pressing the switch stops the motion.
Convenient operation, refer to page 36, via the
remote control.
Convenient closing, refer to page 43, with Com‐
fort Access.
Pinch protection system
If the closing force exceeds a specific value as a
window closes, the closing action is interrupted.
The window reopens slightly.
Danger of pinching even with pinch pro‐
tection
Even with the pinch protection system, check
that the window's closing path is clear; other‐
wise, the closing action may not stop in certain
situations, e.g., if thin objects are present.◀
No window accessories
Do not install any accessories in the range
of movement of the windows; otherwise, the
pinch protection system will be impaired.◀
Closing without the pinch protection
system
Danger of pinching
Monitor the closing process and make
sure that the closing path of the window is clear;
otherwise, injuries may result.◀
For example, if there is an external danger or if
ice on the windows prevents a window from
closing normally, proceed as follows:
1.Pull the switch past the resistance point and
hold it there.
Pinch protection is limited and the window
reopens slightly if the closing force exceeds
a certain value.2.Pull the switch past the resistance point
again within approx. 4 seconds and hold it
there.The window closes without pinch protec‐
tion.
Safety switch
The safety switch in the driver's door can be
used to prevent children, for example, from
opening and closing the rear windows using the
switches in the rear.
Switching on and off Press the button.

blind for the rear window after having activated
it a number of times in a row, the system is
blocked for a limited time to prevent overheat‐
ing. Let the system cool.
The roller sunblind for the rear window cannot

DrivingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for

The radio ready state is activated by pressing
the Start/Stop button in the following situations:
▷When the engine is running.▷When the engine is switched off automati‐
cally using the Auto Start/Stop function and
the brake is not applied.
Some electronic systems/power consumers re‐
main ready for operation.
Radio ready state is switched off automatically:
▷After approx. 8 minutes.▷When the vehicle is locked using the central
locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.

Transmission position P with the ignition
off
When the ignition is switched off, position P is
engaged automatically. When in an automatic
car wash, for example, ensure that the ignition is
not switched off accidentally.◀
The ignition is switched off automatically in the
following situations while the vehicle is station‐
ary and the engine is off:▷When locking the vehicle, and when the low
beams are activated.▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available when
the low beams are switched off.▷When opening and closing the driver door, if
the driver's seat belt is unbuckled and the
low beams are switched off.▷While the driver's seat belt is unbuckled, if
the driver's door is open and the low beams
are switched off.
When the ignition is switched off, by opening or
closing the driver's door or unbuckling the driv‐
er's seat belt, the radio ready state remains ac‐
tive.
Drive readiness
When drive readiness is activated, the vehicle is
operational. The activated drive readiness is the
equivalent of starting the engine in conventional
vehicles.
The following are the different drive readiness
variants:
▷Electric driving, refer to page 67:
The combustion engine is not switched on.▷Driving with the combustion engine, refer to
page 67:
The vehicle is powered by the combustion
engine.Drive readiness in detail

ready state if the conditions for electric driving,
refer to page 67, have been met.
Display The READY display indicates
that the vehicle is ready for driv‐
ing.
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
road users will not be as aware of the vehicle as
they usually would with a conventional engine.
For instance, pay particular attention when ma‐
neuvering into and out of a parking space.◀

ically in the following situations after an auto‐
matic engine stop:
▷When the driver's door is open and neither
the brake nor accelerator pedal are de‐
pressed.▷When the hood is unlocked.
The indicator lamps come on. The combustion

checked.
Electric driving: eDRIVE
Requirements
Electric driving is possible under the following
conditions:
▷The speed does not exceed 35 mph, approx.
60 km/h.▷The high-voltage battery is sufficiently
charged.▷Transmission position D or R is engaged.▷The drive system is at operating tempera‐
ture.▷The accelerator pedal is only slightly de‐
pressed.▷The driver's door is closed.
In addition, the combustion engine is switched
off during braking even below 50 mph, approx.
80 km/h or when coasting below 35 mph, ap‐
prox. 60 km/h.
In ECO PRO mode, already when coasting be‐
low 100 mph, approx. 160 km/h.
Possible cruising range
Depending on the charge of the high-voltage
battery, the vehicle can generally be driven us‐
ing electric power up to 2 miles, approx. 3.5 km.
Driving with the combustion
engine: DRIVE
The combustion engine provides the drive
power to propel the vehicle. The high-voltage
battery is charged at the same time.
Automatic start while driving
The combustion engine is automatically started
under the following conditions while driving:
▷Transmission position M/S is engaged.▷The speed does not exceed 35 mph, approx.
60 km/h.▷The high-voltage battery charge is insuffi‐
cient or it is fully charged, such as when driv‐
ing downhill.▷The required power output is increased,
such as due to the accelerator pedal position
or driving uphill.Seite 67DrivingControls67
