Operational readiness of airbag
system
When the ignition is switched on, refer
to page 60, the warning lamp comes on
briefly to indicate that the entire airbag
system and the belt tensioners are operational.
Airbag system malfunction
▷The warning lamp does not light up after
the ignition is switched on.▷Warning light remains permanently on.
Have the airbag system checked without
delay if there is a malfunction
In the event of a malfunction in the airbag sys‐
tem, have it checked without delay; otherwise,
there is the risk that the system will not func‐
tion as intended even if a sufficiently severe
accident occurs.◀
FTM Flat Tire Monitor The conceptThe system does not measure the actual infla‐
tion pressure in the tires.
It detects a pressure loss in a tire by comparing
the rotational speeds of the individual wheels
while moving.
In the event of a pressure loss, the diameter
and therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable signaling of a flat tire is not en‐
sured. Initialize the system after each correc‐
tion of the tire inflation pressure and after
every tire or wheel change.
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
cannot be detected. Therefore, check the tire
inflation 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.
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.
1."Vehicle Info"2."Vehicle status"3. "Flat Tire Monitor"
The status is displayed.
Initialization
The 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.

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.◀
Tire Pressure Monitor TPMThe concept
The system monitors the tire pressure in the
four mounted tires. The system issues a warn‐
ing if there is a significant loss of pressure in
one or more tires. Sensors in the tire valves
measure the tire pressure.
Notes Tire damage caused by external influen‐
ces
Sudden tire damage caused by external influ‐
ences cannot be indicated in advance.◀
To operate the system, also note the additional
information and instructions contained under
Tire inflation pressure, refer to page 232.
Functional requirements
The system must have been reset while the in‐
flation pressure was correct; otherwise, reliable
signaling of pressure loss is not ensured.
Reset the system after adjusting the tire infla‐
tion pressure and after changing a tire or
wheel.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Status display1."Vehicle Info"2."Vehicle status"3. "TPM"
The status is displayed.
Status indicator on the Control
Display
The tire and system status is indicated by the
color of the tires.
A change in the tire inflation pressure during
driving is taken into account.
All wheels are green The system is active and issues warnings in
case of deviations from the tire inflation pres‐
sures stored last.
"TPM active" appears on the Control Display.

change and issues warnings when the tire
pressure deviates from the tire inflation
pressures stored last.▷A flat tire in one or more tires while the sys‐
tem is being reset.
A message appears on the Control Display.
The wheels are gray The system cannot detect a flat tire.
Possible reasons for this:
▷TPM is being reset.▷Disturbance by systems or devices with
the same radio frequency.▷Malfunction.
Status information
The status control display additionally shows
the current tire inflation pressures. It shows the actual values read; they may vary depending
on driving style or weather conditions.

tion pressure and every time a tire or wheel is
changed.1."Vehicle Info"2."Vehicle status"3."Reset"4.Start the engine, but do not start driving.5.Start the system reset with "Reset".6.Drive away.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After a short trip at over 30 km/h, the set tire
inflation pressures are adopted as target val‐
ues. The system reset is completed as you
drive, and can be interrupted at any time.
When driving resumes, the reset is continued
automatically. On the Control Display, the tires
are shown in green and "TPM active" is dis‐
played again.
The trip can be interrupted at any time. When
driving resumes, the reset is continued auto‐
matically.
If a flat tire is detected while the system is re‐
setting, all tires on the Control Display are dis‐
played in yellow. The message "Low tire!" is
shown.
Low tire pressure message The small warning light lights up yel‐
low and the large warning light lights
up red. A message appears on the
Control Display. In addition, a signal
sounds.
▷There is a flat tire or a major loss in tire in‐
flation pressure.▷The system was not reset. The system
therefore issues warnings in case of devia‐
tions from the tire inflation pressures
stored last.Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers.
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
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, the Tire Pressure Monitor may
not have been reset. Reset the system.
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 ap‐
prox. 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‐
