senger airbags lights up. This indicates that the
child seat has been detected and the front pas‐
senger airbags are not activated.
Strength of the driver's and front
passenger airbag
The strength with which the driver's and front
passenger airbags are triggered depends on the
position of the driver's and front passenger
seats.
To maintain the accuracy of this function over
the long-term, calibrate the front seats when a
corresponding message appears on the Control
Display.
Calibrating the front seats
A corresponding message appears on the Con‐
trol Display.1.Move the respective seat forward all the
way.2.Move the respective seat forward again. It
moves forward briefly.3.Readjust the seat to the desired position.
The calibration procedure is completed when
the message on the Control Display disappears.
If the message continues to be displayed, repeat
the calibration.
If the message does not disappear after a repeat
calibration, have the system checked as soon as
possible.
Unobstructed area of movement
Ensure that the area of movement of the
seats is unobstructed to avoid personal injury or
damage to objects.◀
Tire Pressure Monitor TPM
The concept
The system monitors tire pressure in the four
mounted tires. The system warns you if there is
a significant loss of pressure in one or more tires.
For this purpose, sensors in the tire valves
measure the tire pressure and tire temperature.
Hints Tire damage due to external factors
Sudden tire damage caused by external
influences cannot be indicated in advance.◀
Pay attention to the other information and indi‐
cations under Tire inflation pressure, refer to
page 178, as well when using the system.
Functional requirements
The system must have been reset with the cor‐
rect tire inflation pressure; otherwise, reliable
signaling of tire pressure loss is not ensured.
Reset the system again after each correction of
the tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.
Status display
The current status of the Tire Pressure Monitor
TPM can be displayed on the Control Display,
e.g., whether or not the TPM is active.1."Vehicle Info"2."Vehicle status"3. "Tire Pressure Monitor - TPM"
The status is displayed.
Status display
The tire and system status is indicated by the
color of the tires and a text message on the Con‐
trol Display.

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 in‐
flation 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 192, 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.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
Use of tire sealant, e.g., the Mobility System,
may damage the TPM wheel electronics. In
this case, have the electronics checked at
the next opportunity and have them re‐
placed if necessary.Seite 96ControlsSafety96
Online Edition for Part no. 01 40 2 917 801 - II/13
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.3.Check the air pressure in all four tires at the
next opportunity.
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.
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 approx.
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 depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending 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 prop‐
erties.◀
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 con‐
tinue driving, and contact your service center. ◀
Message when the system was not
reset
A Check Control message is displayed.
The system has detected a wheel change, but
no reset was carried out
Warnings regarding the current tire inflation
pressure are not reliable.
Check the tire inflation pressure and carry out a
reset of the system.
System limits
The system does not function properly if a reset
has not been carried out, e.g., a flat tire is re‐
ported even though the tire inflation pressures
are correct.
The tire pressure depends on the temperature
of the tire. If the tire temperature rises, e.g., due
to driving or because of the heat of the Sun, the
tire inflation pressure increases also. The tire
pressure is reduced when the tire temperature
falls again. This behavior may cause a warning
to be issued if 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 pressure can be detected.
