InitializationThe initialization process adopts the set infla‐
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains.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 corre‐
sponding symbol and "RESET" are dis‐
played.5.Press and hold the button until the display
changes.6.Drive away.
Initialization is completed while the car is
traveling without feedback being given.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 162, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire sidewall.
WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-flat
tires can maintain limited stability. There is risk
of an accident. Do not continue driving if the
vehicle is not equipped with run-flat tires. Fol‐
low the information on run-flat tires and con‐
tinued driving with these tires. ◀
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 162, 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 identification of flat tire damage is not
possible, please contact a dealer’s serviceSeite 78CONTROLSSafety78
Online Edition for Part no. 01 40 2 964 433 - VI/15
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 162, are la‐
beled on the tire sidewall with a circular
symbol containing the letters RSC.
WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-flat
tires can maintain limited stability. There is risk

Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of the tire.
Reduce your speed and stop. Parts of tires can
peel away, which could cause an accident.
Do not continue driving. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.
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.
The system cannot indicate sudden serious tire
damage caused by external circumstances.
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.
Examples and recommendations in the follow‐
ing situations:▷A wheel without TPM electronics is
mounted.
Have it checked by a dealer’s service center
or another qualified service center or repair
shop as needed.▷Malfunction:
Have system checked by a dealer’s service
center or another qualified service center or
repair shop.
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.).

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.

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 85Driving stability control systemsCONTROLS85
