Actions in the event of a 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.
If the defective tire continues to lose pres‐
sure, its position will be indicated to you on
the Control Display.3.At the next opportunity, check the inflation
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.
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 ap‐
prox. 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.◀
Tire Pressure Monitor TPMThe concept
The tire inflation pressure is measured in the
four mounted tires. The system notifies you if
there is a significant loss of pressure in one or
more tires.
Functional requirements The system must have been reset while the in‐
flation pressure was correct; otherwise, reliable
signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
The system does not operate correctly if it has
not been reset. For example, a flat tire may beSeite 90ControlsSafety90

indicated despite correct tire inflation pres‐
sures.
The system is inactive and cannot indicate a
flat tire:▷If a wheel without TPM electronics is
mounted, e.g., compact wheel.▷When the TPM is disturbed by other sys‐
tems or devices with the same radio fre‐
quency.

The trip can be interrupted at any time. If you
drive away again, the process resumes auto‐
matically. Do not reset the system when driv‐
ing with a compact wheel.
If a flat tire is detected while the system is re‐
setting, all tires on the Control Display are dis‐
played in yellow. The message "Low tire!" is
shown.

Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers.
Do not continue driving without run-flat
tires
If the vehicle is not equipped with run-flat tires
as provided at the factory, do not continue
driving. Continuing to drive could cause severe
accidents.◀

Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the
course of the road and the traffic situation.
In the event of a warning, do not jerk the steer‐
ing wheel; otherwise, you may lose control
over the vehicle.◀
The system may not be fully functional in the
following situations:
▷In heavy fog, rain or snowfall.▷In the event of worn, poorly visible, merg‐
ing, diverging, or multiple lane markings
such as in construction areas.▷When the lane markings are covered by
snow, ice, dirt or water.▷In tight curves or on narrow lanes.▷When the lane markings are covered by
objects.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights.▷When the windshield is fogged over, dirty
or covered by a sticker, etc., in front of the
interior rearview mirror.
Malfunctions

Driving stability control systemsVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to 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.
CBC Cornering Brake
Control
When braking during curves or when braking
during a lane change, driving stability and
steering response are improved further.
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistantWhen you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the short‐
est possible braking distance during full brak‐ing. This system utilizes all of the benefits pro‐
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Dynamic Stability Control DSC
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
speed and by applying brakes to the individual
wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Do not reduce the additional safety margin
with a risky driving style, as otherwise there is
a risk of an accident.◀
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in bends.
To increase vehicle stability, activate DSC
again as soon as possible.Seite 96ControlsDriving stability control systems96

greater the drive forces in the associated
wheel.
The transparent arrows indicate the maximum
value the drive forces over the last 10 seconds.
Malfunction
Malfunctions are displayed via Check Control,
refer to page 76.
Hill Descent Control HDC The conceptHDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. The vehicle moves at ap‐
proximately walking speed without braking in‐
tervention by the driver.
You can activate the Hill Descent Control at
speeds below approx. 22 mph/35 km/h. When
moving downhill at speeds below approx.
22 mph/35 km/h, the vehicle reduces its speed
to approximately walking speed, approx.
5 mph/8 km/h and keeps it constant.
Only use HDC in transmission positions D or R.
Increasing or reducing speed
The speed can be changed in the range from
approx. 4 mph/6 km/h to ap‐
prox. 15 mph/25 km/h by pressing the acceler‐
ator or brake pedal lightly.
A target speed within the same range can be
specified using the lever of the cruise control.
On inclines over 10 %, you can reduce the
speed to approx. 3 mph/4 km/h. Pull the lever
of the cruise control beyond the resistance point, arrow 3.1Increasing speed2Pull to the resistance point: reduce the
speed to approx. 4 mph/6 km/h3Pull beyond the resistance point: on in‐
clines over 10 %, reduce the speed to ap‐
prox. 3 mph/4 km/h
Activating HDC
Press the button; the LED above the button
lights up.
The LED flashes when the brakes are applied
automatically.
Deactivating HDC
Press the button again; the LED goes out.
HDC is automatically deactivated above ap‐
prox. 37 mph/60 km/h.

Best results are achieved when using the sys‐
tem on well-developed roads and highways.
The desired speed can be selected between
20 mph/30 km/h and 110 mph/180 km/h.
The system can also be activated when sta‐
tionary.
Comply with the legal speed limit in every sit‐
uation when using the system.
Detection range
The detection capacity of the system and the
automatic braking capacity are limited. Two-
wheeled vehicles driving ahead of you for in‐
stance might not be detected.
Limited detection capacity
Because of the limits to the detection ca‐
pacity, you should be alert at all times so that
you can intervene actively, if necessary; other‐
wise, there is the danger of an accident occur‐
ring.◀
Deceleration
The system does not decelerate when a sta‐
tionary obstacle is located in the same lane,
e.g., a vehicle at a red traffic light or at the end
of traffic congestion.
The system also does not respond to:▷Pedestrians or similarly slow road users.▷Red traffic lights.▷Stationary objects.▷Cross traffic.▷Approaching traffic.
No warnings
A warning may not be issued when ap‐
proaching a stationary or very slow-moving ob‐
stacle. Take action yourself, otherwise there is
a risk of an accident.◀
Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
Swerving vehicles
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
