One wheel is yellow
A flat tire or major drop in inflation pressure in
the indicated tire.
All wheels are yellow
A flat tire or major drop in inflation pressure in
several tires.
Wheels, gray
The system cannot detect a flat tire. Reasons for
this may be:▷The system is being reset.▷Malfunction.
For Canadian models: Additional
information
The status display additionally shows the cur‐
rent tire inflation pressures and tire tempera‐
tures. The values shown are current measure‐
ment values and may vary depending on driving
style or weather conditions.
Carry out reset
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.

The tires are shown in gray and the status is dis‐
played.
After driving faster than 19 mph/30 km/h for a
short period, the tire inflation pressures set are
accepted as reference values. The reset is com‐
pleted automatically during driving. After suc‐
cessful completion of the reset, the tires appear
in green on the Control Display and "TPM
active" is displayed.
The trip can be interrupted at any time. If you
drive away again, the reset resumes automati‐
cally.
Low tire pressure message The yellow warning lamp lights up. A
Check Control message is displayed.▷There is a flat tire or a major loss in
tire inflation pressure.▷A reset of the system was not carried out af‐
ter a wheel was changed. The system there‐
fore issues a warning based on the tire pres‐
sures before the last reset.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with reg‐
ular tires or run-flat tires.
Run-flat tires, refer to page 181, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a low inflation pressure is indicated, DSC
Dynamic Stability Control is switched on if nec‐
essary.
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, it is possible that a reset was not
carried out for the Tire Pressure Monitor. In
that case, carry out a reset.Seite 103SafetyControls103

The status is displayed.
Initialization
The initialization process adopts the set inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming the inflation pressures.
Do not initialize the system when driving with
snow chains.

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 can‐
not be detected. Therefore, check the tire infla‐
tion 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.

Driving stability control systemsVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Antilock Brake System ABS
ABS prevents locking of the wheels during brak‐
ing.
The vehicle remains steerable 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 maximum braking
force boost. It thus helps to achieve the shortest
possible braking distance during full braking.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.1.Hold the vehicle in place with the foot brake.2.Release the foot brake and drive away with‐
out delay.After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 2 seconds and the vehicle will begin rolling
back.◀
DSC Dynamic Stability
Control
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. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes at 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.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Indicator/warning lamps The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.Seite 117Driving stability control systemsControls117

When DSC OFF, refer to page 118, is active,
driving stability is limited during acceleration
and when driving in bends.
TRACTION
When TRACTION is active, the vehicle has max‐
imum traction on loose road surfaces. DTC Dy‐
namic Traction Control, refer to page 118, is ac‐
tivated. Driving stability is limited during
acceleration and when driving in bends.

The driver handles several of the stabilization
tasks.
Activating SPORT+ Press the button repeatedly until
SPORT+ appears in the tachometer
and the DSC OFF indicator lamp lights up in the
instrument cluster.

Display
Signal tones
When approaching an object, an intermittent
tone is sounded that indicates the position of the
object. For example, if an object is detected to
the left rear of the vehicle, a signal tone sounds
from the left rear speaker.
The shorter the distance to the object becomes,
the shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
If objects are located both in front of and behind
the vehicle, an alternating continuous signal is
sounded.
The intermittent tone is interrupted after approx.
3 seconds:▷If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.▷If moving parallel to a wall.
The signal tone is switched off:
▷When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.▷When transmission position P is engaged.
Volume
The volume of the PDC signal can be adjusted,
refer to user's manual for Navigation, Entertain‐
ment and Communication.
The setting is stored for the remote control cur‐
rently in use.
Visual warning
The approach of the vehicle to an object can be
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis‐
play before a signal tone sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.
The range of the sensors is represented in col‐
ors: red, green and yellow.
If the backup camera image was selected last, it
again appears on the display. To switch to PDC:

Detection of objects
High, protruding objects such as ledges may not
be detected by the backup camera.
Top View
The concept
Top View assists you in parking and maneuver‐
ing. The area around the doors and the road area
around the vehicle are shown on the Control
Display for this purpose.
General information
The image is captured by two cameras
integrated in the exterior mirrors and by the
backup camera.
The range is at least 7 ft/2 m to the side and rear.
In this way, obstacles up to the height of the ex‐
terior mirrors are detected early.
Notes Check the traffic situation as well
Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside the picture area of the cameras.◀
