When a gear is engaged, the engine starts au‐
tomatically.
The air flow from the air conditioner is reduced
when the engine is switched off.

PrewarningThis warning is issued, for example, when there
is the impending danger of a collision or the
distance to the vehicle ahead is too small.
The driver must intervene actively when there is a prewarning.
Acute warning with braking function
Acute warning in displayed in case of the immi‐
nent danger of a collision when the vehicle ap‐
proaches another object at a high differential
speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking inter‐
vention in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
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 booster
is sufficiently quick and sufficiently hard step‐
ping on the brake pedal. The system can assist
with some braking intervention if there is a risk
of a collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: During a braking inter‐
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if ve‐
hicle stability has not been restricted, e.g. by
deactivating the DSC Dynamic Stability Control.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by actively
moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.System limits
Information WARNING
The system can react incorrectly or not at
all due to the system limits. There is risk of acci‐
dents or risk of property damage. Observe the
information regarding the system limits and ac‐
tively intervene, if needed. ◀
Detection range The system's detection potential is limited.
Thus a system reaction might not come or
might come 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 field of view of the camera or the
windshield are dirty or covered.▷If the driving stability control systems are
deactivated, for example DSC OFF.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If there are constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.Seite 118CONTROLSSafety118

System limits
Information WARNING
The system can react incorrectly or not at
all due to the system limits. There is risk of acci‐
dents or risk of property damage. Observe the
information regarding the system limits and ac‐
tively intervene, if needed. ◀
Detection range The detection potential of the camera is lim‐
ited.
Thus a warning might not be issued or be is‐
sued late.
E. g. the following situations may not be de‐
tected:▷Partially covered pedestrians.▷Pedestrians that are not detected as such
because of the viewing angle or contour.▷Pedestrians outside of the detection range.▷Pedestrians having a body size less than
32 inches/80 cm.
Functional limitations
The system may not be fully functional or may
not be available in the following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the field of view of the camera or the
windshield are dirty or covered.▷If the driving stability control systems are
deactivated, for example DSC OFF.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If there are constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.▷When it is dark outside.
Brake force display
The concept
▷During normal brake application, the brake
lights light up.▷During heavy brake application, the flash‐
ers light up in addition.
Post Crash — iBrake
In the event of an accident, the system canbring 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 vehi‐
cle to brake harder. This interrupts automatic
braking. Destepping on the gas pedal also in‐
terrupts automatic braking.
After coming to a halt, the brake is released au‐
tomatically. Secure the vehicle against rolling.

Dynamic Damping Con‐
trol
The concept
The tuning of the suspension can be changed
with the system.
Programs The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 124.

ers for greater driving agility.
Driving Dynamics Con‐

The Driving Dynamics Control helps to fine-
tune the vehicle's settings and features. Choose
between three different programs. Driving Dy‐
namics Control will activate the particular pro‐
gram.

MID For balanced tuning.
With each starting operation, MID is activated
using the Start/Stop button.

Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system decelerates
you may compensate it by briefly accelerating.
After releasing the gas pedal the system is reac‐
tivated and controls speed independently.
Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected.
Drive attentively, and react to the current traffic
situation. If necessary, intervene actively, for
example by braking, steering or evading.
Engine power
The desired speed may not be maintained on
uphill grades if engine power is insufficient.
Malfunction A Check Control message is displayed if the sys‐
tem fails or was automatically deactivated.
The system may not be fully functional in the
following situations:▷When an object was not correctly detected.▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the field of view of the camera or the
windshield are dirty or covered.▷When driving toward bright lights.▷Up to 20 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.
Cruise control
The concept
Using this system, a desired speed can be ad‐
justed using the buttons on the steering wheel.
The system maintains the desired speed. The
system accelerates and brakes automatically as
needed.
General information
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
Depending on the driving settings, the features
of the cruise control can change in certain
areas.

InformationA component of the parking assistant is the
PDC Park Distance Control, refer to page 134.
When parking, also take note of the visual and
acoustic information issued by the PDC, the
parking assistant and, where applicable, the
rearview camera, and react accordingly.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal tone.
WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the re‐
spective situations. ◀
ATTENTION
The parking assistant can steer the vehi‐
cle over or onto curbs. There is a risk of damage
to property. Watch traffic closely and actively intervene in the respective situations. ◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.
