▷Inflation was not carried out according to
specifications.▷The tire inflation pressure has fallen below
the level of the last confirmation.
In this case:
▷Check the tire pressure and correct as
needed.▷Carry out a reset of the system after a tire
change.
System limits
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported though tire inflation pressures are
correct.
The tire inflation pressure depends on the
tire's temperature. Driving or exposure to the
sun will increase the tire's temperature, thus
increasing the tire inflation pressure. The tire
inflation pressure is reduced when the tire
temperature falls again. These circumstances
may cause a warning when temperatures fall
very sharply.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire inflation pressure can be de‐
tected.
Display in the following situations:
▷A wheel without TPM electronics is fitted:
have the service center check it if needed.▷Malfunction: have the system checked by
your service center.▷TPM was unable to complete the reset.
Reset the system again.▷Interference through systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the
level to trigger illumination of the TPMS low
tire pressure telltale. Your vehicle has also
been equipped with a TPMS malfunction indi‐
cator to indicate when the system is not oper‐
ating properly. The TPMS malfunction indica‐
tor is combined with the low tire pressure
telltale. When the system detects a malfunc‐
tion, the telltale will flash for approximately one
minute and then remain continuously illumi‐
nated. This sequence will continue upon sub‐
sequent vehicle start-ups as long as the mal‐
function exists. When the malfunction indicator
is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace‐
ment or alternate tires or wheels on the vehicleSeite 110ControlsSafety110

Driving comfortVehicle features and options
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
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Cruise control The concept The system maintains a preset speed via the
buttons on the steering wheel. The system brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant 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 vehi‐
cle and cause an accident.◀

The displays go out. The stored desired speed
is deleted.
Interrupting When active, press the button.
The system is automatically interrupted if:▷The brakes are applied.▷The clutch pedal is depressed for a few
seconds or released while a gear is not en‐
gaged.▷Selector lever position D is disengaged.▷MDM is activated or DSC is deactivated.▷DSC is actively controlling stability.
Maintaining, storing, and changing the
speed
Hints Adjusting the desired speed
Modify desired speed to road conditions
and be ready to brake at all times; otherwise,
there is the risk of an accident.◀
Maintaining/storing the speed Press button.
Or:
Press the rocker switch while the system is in‐
terrupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
This is displayed, refer to page 134, in the
speedometer and briefly in the instrument
cluster.
When cruise control is maintained or stored,
DSC Dynamic Stability Control will be turned
on if needed.
Changing the speed
Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the
vehicle reaches the stored speed when the
road is clear.▷Each time the rocker switch is pressed to
the point of resistance, the desired speed
increases or decreases by approx.
1 mph/1 km/h.▷Each time the rocker switch is pressed
past the point of resistance, the desired
speed increases or decreases by a maxi‐
mum of 5 mph/10 km/h.
The maximum speed that can be set de‐
pends on the vehicle.▷Pressing the rocker switch to the resist‐
ance point and holding it accelerates or de‐
celerates the vehicle without requiring
pressure on the accelerator pedal.
After the rocker switch is released, the ve‐
hicle maintains its final speed. Pressing the
switch beyond the resistance point causes
the vehicle to accelerate more rapidly.
Resuming the desired speed
Press button.
The stored speed is reached and maintained. Displays in the instrument cluster

PDC Park Distance Control
The concept PDC is a support when parking. When you
slowly approach an object in the rear - or also
in the front of the vehicle if the feature is availa‐
ble - then the object is reported through:
▷Signal tones.▷Visual display.
General information
Ultrasound sensors in the bumpers measure
the distances from objects.
The maneuvering range, depending on the ob‐
stacle and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given:▷By the front sensors and the two rear cor‐
ner sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
To ensure full functionality:
▷Do not cover sensors, e.g., with stickers,
bicycle racks.▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and
maintain a distance of at least 12 in/30 cm.
Hints
Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
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 - risk of accident.◀
Avoid driving fast with PDC
Avoid approaching an object too fast.
Avoid driving off fast while PDC is not yet ac‐
tive.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
