bility Control is switched on if necessary.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
The system could be delayed or malfunction in
the following situations:
▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive
wheels, high lateral acceleration.▷When driving with snow chains.
Actions in the event of a flat tire
Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.Seite 99SafetyControls99

If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
Run-flat tires
Maximum speed
You can continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at
the next opportunity.
If the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx.
50 miles/80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e.g., curbs, potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending on the driving speed, road
conditions, external temperature, cargo load,
etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering
properties.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of the tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving, and contact your service
center.◀
Intelligent Safety
The concept Depending on how the vehicle is equipped, In‐
telligent Safety consists of one or more of the
following systems, which can help to avoid an
imminent collision. These systems are active
automatically every time the engine is started
using the Start/Stop button:▷Collision warning, refer to page 101.▷Pedestrian warning, refer to page 106.
Note
Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise an
accident is still possible despite all warnings.◀

Collision warning
Depending on how the equipment is equipped,
the collision warning system consists of one of
the two systems:
▷Collision warning with City Braking func‐
tion, refer to page 104;▷Collision warning with braking function, re‐
fer to page 101Collision warning with
braking function
The concept The system issues a warning if there is immi‐
nent danger of a collision and also includes a
braking function.
If the vehicle is equipped with Active Cruise
Control with Stop & Go, the collision warning is
controlled via the cruise control radar sensor in
conjunction with a camera.
The collision warning is available even if cruise
control has been deactivated.
When the vehicle is intentionally brought close
to a vehicle, the collision warning is delayed to
avoid false warnings.
General information
The system issues a two-phase warning of a
possible danger of collision with vehicles at
speeds above approx. 3 mph/5 km/h. The time
of these warnings may vary depending on the
current driving situation.
Detection range
It responds to stationary or moving objects
that are within the detection range of the radar
system.

Warning stages
Prewarning
This warning is issued, for example, when
there is the impending danger of a collision or
the distance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention may be executed with
maximum braking force and for a brief period
only as necessary.
The intervention can bring the vehicle to a
complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.Seite 102ControlsSafety102

Prewarning sensitivityDepending on the set prewarning time, this
may result in increased false warnings.
Collision warning with City
Braking function
The concept
The system can help to prevent accidents. If
an accident cannot be prevented, the system helps to reduce the collision speed.
The system issues a warning if there is immi‐ nent danger of a collision and if so brakes inde‐
pendently.
The automatic braking intervention is done
with limited force and duration.
The system is controlled via a camera in the
base of the mirror.
The collision warning is available even if cruise
control has been deactivated.
When the vehicle is intentionally brought close
to a vehicle, the collision warning is delayed to
avoid false warnings.
General information The system issues a two-phase warning of a
danger of collision with vehicles at speeds
above approx. 3 mph/5 km/h. The time of these
warnings may vary depending on the current
driving situation.
Up to approx. 35 mph/60 km/h a braking inter‐
vention occurs when appropriate.Detection range
Vehicles are observed when they are traveling
in the same direction of movement if they are
located within the detection range of the sys‐
tem.

Warning with braking function Adapting your speed and driving style
The warning does not relieve the driver
of the responsibility to adapt his or her driving
speed and style to the traffic conditions.◀
Display If a collision with a person detected in this way
is imminent, a warning symbol appears on the
instrument cluster and in the Head-up Display.
The red symbol is displayed and a sig‐
nal sounds.
Intervene immediately by braking or making an
evasive maneuver.
Braking intervention The warning prompts the driver himself to in‐
tervene. During the warning, the maximum
braking force is used, even with light pressure
on the brake pedal. In addition, if there is a risk
of collision, the system can assist with a slight
braking intervention. The intervention can bring a vehicle traveling at slow speed to a
complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
The braking intervention can be interrupted by
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When towing or tow-starting the vehicle,
switch off the pedestrian warning to prevent undesired interventions.
System limits Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the dan‐
ger of an accident occurring.◀
Detection range
The detection capability of the camera is lim‐
ited.
This may result in the warning not being is‐
sued or being issued late.
For example, the following situations may not
be detected:▷Partially covered pedestrians.▷Pedestrians that are not detected as such
because of the viewing angle or contour.▷Pedestrians outside of the detection range.Seite 107SafetyControls107
