Set the parking brake and further secure
the vehicle as required
Set the parking brake firmly when parking; oth‐
erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the ve‐
hicle, for example, by turning the steering
wheel in the direction of the curb. ◀
While driving

braking function:
Pull the switch and hold it. The vehicle brakes
hard while the switch is being pulled.

Releasing Press the switch while the brake is de‐
pressed or transmission position P is en‐
gaged.
The LED and indicator lamp go out.
The parking brake is released. Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, for exam‐
ple, cannot release the parking brake.◀
Automatic release For automatic release, operate the accelerator
pedal.
The LED and indicator lamp go out.
Subject to the following requirements, the
parking brake is automatically released by op‐
eration of the accelerator pedal:▷Engine on.▷Drive position 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.◀

Manual release
The parking brake can be released manually in
the event of a power failure or electrical fault.
Before releasing, secure the vehicle
against rolling
Before releasing the parking brake manually,
and whenever you park the vehicle with the
parking brake released, ensure that position P
of the automatic transmission is engaged.
Secure the vehicle in a manner appropriate to
the inclination of the road, e.g., with a wheel
chock; otherwise, there is the danger of the ve‐
hicle rolling.◀
Unlocking1.Raise the rear cargo floor cover in the
cargo area, arrow 1, and fasten it with a re‐
taining strap.2.Remove the release tool from the onboard
vehicle tool kit.3.Take out the floor trim in the cargo area,
removing the clips with a screwdriver, ar‐
rows.4.Hook the release tool into the release
point, arrow.5.Forcefully pull the release tool up against
the resistance until you notice a marked in‐
crease in the resistance and the parking
brake releases audibly.
Have the malfunction corrected
If the parking brake has been released
manually in response to a malfunction, only
technicians can return it to operation.
Have the malfunction corrected by your serv‐
ice center.◀

After a power failureOnly put the parking brake into operation
after a power failure
The parking brake should only be put into op‐
eration again if it was manually released due to
an interruption in the supply of electrical
power. Otherwise, it cannot be ensured that
the parking brake will function properly.◀
Putting the parking brake into
operation1.Switch on the ignition.2. Press the switch while the brake is
depressed or transmission position P is
engaged.
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.

Automatic Hold
The concept
This system assists the driver by automatically
setting and releasing the brake, such as when
moving in stop-and-go traffic.
The vehicle is automatically held in place when
it is stationary.
On inclines, the system prevents the vehicle
from rolling backward when driving away.
For your safety
Under the following conditions, Automatic
Hold is automatically deactivated and the park‐
ing brake is set:
▷The engine is switched off.▷A door is opened and driver's safety belt is
unbuckled while the vehicle is stationary.▷The moving vehicle is brought to a stand‐
still using the parking brake.
The indicator lamp switches from
green to red and the letters AUTO H go out.

Before driving away:
▷Release the parking brake manually.▷Reactivate Automatic Hold.
Leaving the vehicle with the engine run‐
ning
Before leaving the vehicle with the engine run‐
ning, engage position P of the automatic trans‐
mission and ensure that the parking brake is
set. Otherwise, the vehicle may begin to roll.◀

NotePersonal responsibility
The system cannot possibly serve as a
substitute for the driver's personal judgment of
the traffic situation. The system may not al‐
ways detect critical situations reliably and in a
timely manner. Adapt speed to traffic situation
and drive alertly; otherwise, a risk to safety may
result.◀
Function
After the safety belt is buckled, the front belts
are automatically pretensioned once after the
vehicle is driven is away.
In critical driving situations, the following indi‐
vidual functions become active as needed:▷The front belts are automatically preten‐
sioned.▷Automatic closing of the windows.▷Automatic closing of the glass sunroof.▷For vehicles equipped with Comfort Seats:
automatic positioning of the backrest for
the front passenger seat.
After a critical driving situation without an acci‐
dent, the front belts are loosened again. All
other systems can be restored to the desired
setting.
If the belt tension does not loosen automati‐
cally, stop the vehicle and unbuckle the belt
using the red button in the buckle. Fasten the
belt before continuing on your trip.
PostCrash
In the event of an accident, the system can
bring the car to a halt automatically without in‐
tervention by the driver in certain situations.
This can reduce the risk of a further collision
and the consequences thereof.
Depressing the brake pedal can cause the ve‐
hicle to brake harder. This interrupts automatic
braking. Depressing the accelerator pedal also
interrupts automatic braking.
After coming to a halt, the brake is released
automatically. Secure the vehicle against roll‐
ing.Seite 126ControlsSafety126

Driving stability control systemsVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. This then reduces braking dis‐ tance to a minimum during full braking. This
system utilizes all of the benefits provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
When equipped with Driving Assistant Plus or
with Active Cruise Control with Stop & Go
function, ACC is supported by the braking in‐
tervention if there is a possible risk of collision.
To do this, the braking force is automatically increased if the braking pressure is insufficient
when the brakes are applied.Adaptive brake assistant
In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.
Drive-off assistant
This system supports driving away on gradi‐
ents. The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive away
without delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load or when a trailer
is being used, the vehicle may roll back
slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin
rolling back.◀
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the driving
wheels when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Sub‐
ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine
