Check Control
The concept
The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys‐
tems being monitored.
A Check Control message consists of indicator
and warning lamps in the instrument cluster
and, in some circumstances, an acoustic signal.
Indicator/warning lamps
The indicator and warning lamps can light up in
a variety of combinations and colors in display
area 1 or 2.
Several of the lamps are checked for proper
functioning and light up temporarily when the
engine is started or the ignition is switched on.
The symbol indicates that Check Control
messages have been stored. The Check Control
messages can be displayed later.
What to do in case of a malfunction
The meaning of each lamp in the event of a
malfunction and tips on how to respond are
provided in the list, refer to page 191.

Hiding Check Control messages
Press the button on the turn indicator lever.
Some Check Control messages are displayed
continuously and are not cleared until the mal‐
function is eliminated. If several malfunctions
occur at once, the messages are displayed con‐
secutively.
Other Check Control messages are hidden au‐
tomatically after approx. 20 seconds. However,
they are stored and can be displayed again
later.
Viewing stored Check Control messages
The stored Check Control messages can only be
displayed while the driver's door is closed.

For example, the sensors are unable to detect
fog or hazy weather. To avoid safety risks, you
should always switch on the lamps manually
under these conditions. ◀

Indication of a flat tire
The warning lights come on in yellow
and red. In addition, a signal sounds.
There is a flat tire or a major loss in tire inflation
pressure.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 160, are la‐
beled 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 flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
Actions in the event of a flat tire
Normal tires
1.Identify the damaged tire.
Do this by checking the inflation pressure in
all four tires.
The tire pressure gauge of the Mobility Sys‐
tem, refer to page 161, can be used for this
purpose.
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.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire using the Mobility Sys‐
tem, refer to page 161.
Run-flat tires
You can continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.

Performing a reset
Perform a system reset after adjusting the tire
inflation pressure to a new value and after
changing a tire or wheel.1.Start the engine, but do not start driving.2.Press the button on the turn indicator lever
repeatedly until "SET/INFO" is displayed.3.Press and hold the button until the display
changes.4.Press the button repeatedly until the sym‐
bol for the Tire Pressure Monitor and "AC‐
TIVE" are displayed. The Tire Pressure Mon‐
itor can be reset with "RESET".5.Press and hold the button until "RESET‐
TING" is displayed.6.Drive away.
After a short trip at over 20 mph/30 km/h,
the set tire inflation pressures are adopted
as target values. The reset is completed au‐
tomatically as you drive.
The trip can be interrupted at any time.
When driving resumes, the reset is contin‐
ued automatically.
Low tire pressure message
The warning lights come on in yellow
and red. A Check Control message is
displayed. In addition, a signal sounds.
▷There is a flat tire or substantial loss of infla‐
tion pressure on the indicated wheel.▷The system was not reset after a wheel
change and thus issues warnings based on
the inflation pressures initialized last.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 160, are la‐
beled on the tire sidewall with a circular
symbol containing the letters RSC.Seite 77SafetyCONTROLS77
Online Edition for Part no. 01 40 2 961 084 - II/15
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. ◀
Message indicating that the inflation
pressure needs to be checked
The yellow warning light lights up.
A Check Control message is displayed.▷The system has detected that a wheel was
changed but a reset was not performed.▷The tire was not inflated according to speci‐
fications.▷The tire pressure has dropped since the last
confirmation.
In this case:
▷Check the tire inflation pressure and correct
it if necessary.▷After changing a wheel, reset the system.
System limits
The system will not function properly if a reset
was not performed, e.g., it may identify a tire as
flat although the tire is filled to the correct infla‐
tion pressure.
The tire pressure depends on the temperature
of the tire. An increase in the tire temperature,
e.g., while driving or due to sunlight, increases
the tire inflation pressure. The tire pressure de‐
creases when the tire temperature drops. In
case of severe temperature drops, this behavior
may lead to a warning on account of the de‐
fined warning limits.
Malfunction The yellow warning light flashes yellow
and then lights up continuously.
A Check Control message is displayed.
A flat tire or tire inflation pressure loss cannot
be detected.
Display in the following situations:▷A wheel without TPM electronics is
mounted, e.g., a compact wheel:
Have the system checked by the service
center if necessary.▷Malfunction:
Have the system checked by the service
center.▷TPM was unable to complete the reset.
Reset the system again.
The yellow warning light flashes and
then lights up continuously.
A Check Control message is displayed.
A flat tire or tire inflation pressure loss cannot
be detected.
Display in the following situation:
▷Disturbance by other systems or devices
with the same radio frequency:
After leaving the area of the disturbance,
the system automatically becomes active
again.
Declaration according to NHTSA/FMVSS
138 Tire Pressure Monitoring Systems
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

Deactivating DSC
Press the switch until the DSC OFF indicator
lamp lights up in the speedometer and DSC OFF
appears in the tachometer. DSC is deactivated.
Intervening measures to stabilize the vehicle
and give it forward momentum are no longer
executed.
When driving with snow chains or to rock the
vehicle free of snow, it may be useful to deacti‐
vate DSC temporarily.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the switch again; the DSC indicator lamps
in the display elements go out.
Indicator/warning lights The indicator lamp in the tachometer
flashes: DSC is controlling the drive
forces and brake forces.
The indicator lamp lights up: DSC and DTC has
failed.
The indicator lamp in the speedometer
lights up and DSC OFF appears in the
tachometer.
DSC and DTC deactivated.
Dynamic Traction Con‐
trol DTC
The concept
The DTC system is a version of the DSC in which
forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
▷When driving in sand, on snowy inclines, in
slush, or on unplowed, snow-covered road
surfaces▷When rocking a vehicle free or starting off
in deep snow, sand, or on loose ground▷When driving with snow chains.Seite 82CONTROLSDriving stability control systems82
