Information DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of
the vehicle. There is danger to life. Keep the
exhaust pipe free and ensure sufficient ventila‐
tion.◀
WARNING
An unsecured vehicle can put itself into
motion and roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a slope, turn the
front wheels in the direction of the curb.▷On uphill grades or on a slope, also secure
the vehicle, e.g. with a wheel chock.◀
CAUTION
In the case of repeated starting attempts
or repeated starting in quick succession, the
fuel is not burned or is inadequately burned.
The catalytic converter can overheat. There is
risk of property damage. Avoid repeated start‐
ing in quick succession.◀

WARNING
Your vehicle handles differently when a
run-flat tire is damaged and has low or missing
tire inflation pressure, e.g., your lane stability is
reduced when braking, braking distances are
longer and the self-steering properties will
change. There is risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h.◀
Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of
the tire could come loose and cause an acci‐
dent.
Do not continue driving. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Intelligent Safety The concept
Intelligent Safety enables central operation of
the driver assistance system. Depending on
how the vehicle is equipped, Intelligent Safety
consists of one or more systems that can help
prevent a imminent collision.▷Front-end collision warning with City Brak‐
ing function, refer to page 112.▷Pedestrian warning, refer to page 114.▷Lane departure warning, refer to
page 117.
Information
WARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to sys‐
tem limits, warnings or reactions of the system
may not be output or they may be output too
late or incorrectly. There is risk of an accident.
Adjust the driving style to the traffic condi‐
tions. Watch traffic closely and actively inter‐
fere in the respective situations.◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g. approach control warning with light brak‐
ing function. There is risk of an accident.
Switch all Intelligent Safety systems off prior to
tow-starting/towing.◀

Prewarning
This warning is issued, e.g., 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 relatively high dif‐
ferential 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 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.
System limits
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 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 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.
Warning sensitivity
The more sensitive the warning settings are,
e.g. the warning time, the more warnings are
displayed. However, there may also be an ex‐
cess of false warnings.
Pedestrian warning with city
braking function
The concept The system can help prevent accidents with
pedestrians.
The system issues a warning in the city driving
speed area if there is imminent danger of a col‐

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.
Lane departure warning
The concept Starting at a specific speed, this system alerts
you when the vehicle on streets with lane
markings is about to leave the lane. This
speed, depending on the country version, is
between 35 mph/55 km/h and
45 mph/70 km/h.
The steering wheel begins vibrating gently in
the event of warnings. The time of the warning
may vary depending on the current driving sit‐
uation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
Information WARNING
The system does not relieve from the
personal responsibility to correctly assess
route and traffic situation. There is risk of an
accident. Adjust the driving style to the traffic
conditions. Watch traffic closely and actively interfere in the respective situations. In the
event of a warning, do not unnecessarily jerk
the steering wheel.◀
