Run-flat tiresMaximum speed
You may 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 cargo load, driv‐
ing style and road conditions.
A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
A vehicle with a damaged tire reacts differently,
e.g., it has reduced lane stability during brak‐
ing, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering ma‐
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be shorter or longer de‐
pending 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.
Your car handles differently when you lose tire
inflation pressure, e.g., your lane stability is re‐
duced when braking, braking distances are lon‐
ger and the self-steering properties will
change. ◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of a 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
Intelligent Safety enables central operation of
the driver assistance system.
The intelligent safety systems can hel prevent
an imminent collision.▷Front-end collision warning with City Brak‐
ing function, refer to page 87.▷Pedestrian warning with city braking func‐
tion, refer to page 90
Hints
Personal responsibility
The system does not serve as a substitute
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 acci‐
dents are still possible despite all warnings. ◀
Adapting your speed and driving style
The displays and warnings of the system
do not relieve the driver of the responsibility to
adapt his or her driving speed and style to the
traffic conditions. ◀

Warning with braking function
Display
If a collision with a vehicle detected in this way
is imminent, a warning symbol appears on the
instrument cluster.
SymbolMeasureThe vehicle lights up red: prewarning.
Brake and increase distance.The vehicle flashes red and an acous‐
tic signal sounds: acute warning.
You are requested to intervene by
braking or make an evasive maneu‐
ver.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
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively 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 prewarning.
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 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 DSC Dynamic Stability Control is switched on.
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.

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 in/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 camera viewing field or the front
windshield are dirty or covered.▷If the driving stability control systems are
deactivated, e.g. DSC OFF.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop knob.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is constant blinding effects because
of oncoming light, e. g., from the sun low in
the sky.▷When it is dark outside.

Driving stability control systemsVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Antilock Brake System
ABS
ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power 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 greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.DSC Dynamic Stability
Control
The concept
DSC prevents traction loss in the power wheels
when driving off and accelerating.
DSC also recognizes unstable vehicle conditions
such as fishtailing or nose-diving. Within the
physical limits DSC helps to keep the vehicle on
a steady course by reducing engine speed and
by applying brakes to the individual wheels.
Adjust your driving style to the situationAn appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner. ◀
Indicator/warning lights The indicator lamp flashes: DSC controls
the drive and braking forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
curves.
To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC Press and hold this button but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and displays DSC OFF.Seite 94CONTROLSDriving stability control systems94

Camera-based cruise con‐
trol, ACC
The concept
Use this system to select a desired speed that
the vehicle will maintain automatically on clear
roads.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you.
A camera on the interior rear view mirror is
used to detect vehicles driving ahead.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied.
For safety reasons, it depends on the speed.
To maintain a certain distance, the system au‐
tomatically decelerates, applies the brakes
lightly, or accelerates again if the vehicle ahead
begins moving faster.
As soon as the road is clear, the vehicle acceler‐
ates to the desired speed.
The speed is also maintained downhill, but may
not be maintained uphill if engine power is in‐
sufficient.General information
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
Depending on the set drive mode, refer to
page 96, the features of the cruise control can
change in certain areas.
Hints Personal responsibility
Even an active system holds the driver re‐
sponsible for his or her driving, particularly for
staying in your lane, adjusting your speed,
keeping your distance and for your driving style
all in relation to traffic.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed, e.g. through braking,
steering or make evasive maneuvers - risk of
accident. ◀
Unfavorable weather conditions
In the event of unfavorable weather and
light conditions, for instance if there is rain,
snowfall, slush, fog or glare, this may result in
poorer recognition of traffic situations as well
as short-term interruptions for vehicles that are
already detected. Drive attentively, and react to
the current traffic situation. Intervene actively
when necessary, e.g., by braking, steering or
making an evasive maneuver, otherwise, there
is the risk of an accident. ◀Seite 98CONTROLSDriving comfort98

Cruise controlThe concept
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking is insufficient.
Unfavorable conditions
Do not use the system if unfavorable con‐
ditions make it impossible to drive at a constant
speed, e.g.:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehicle
and cause an accident. ◀

The malfunction is signaled by a continuous
tone alternating between the front and rear
speakers. As soon as the malfunction due
to other ultrasound sources is no longer
present, the system is again fully functional.
Malfunction

To ensure full functionality:
▷Keep the sensors clean and free of ice.▷dimmedDo not put any stickers on sensors.▷When using high-pressure washers, do not
spray the sensors for long periods and
maintain a distance of at least 12 in/30 cm.
Parking assistant
The concept
This system assists the driver in parking parallel
to the road.
Ultrasound sensors measure parking spaces on
both sides of the vehicle.
The parking assistant calculates the best possi‐
ble parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information issued by the PDC and the
parking assistant and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 106.
Hints
Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.

Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed - risk of accident. ◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the
system.
Therefore, always be alert and ready to inter‐ vene; otherwise, there is the risk of an acci‐
dent. ◀
Transporting cargo
Cargo that extends beyond the perimeter
of the vehicle is not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent. ◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curb if need be.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged. ◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.
