The concept
The enabled alarm system reacts to the follow‐
ing:
▷Opening of a door, the hood or the tailgate.▷Movements inside the vehicle.▷Changes in the vehicle tilt, e.g., during at‐
tempts to steal a wheel or tow the car.▷Interruptions in battery voltage.
Depending on the market-specific version, the
alarm system briefly signals unauthorized entry
attempts by:
▷By sounding an acoustic alarm.▷By switching on the hazard warning system.Arming and disarming the alarm system

Operational readiness of airbag system
In the radio ready state and beyond, re‐
fer to page 57, the warning light lights
up briefly to indicate that the entire air‐
bag system and the belt tensioners are opera‐
tional.
Airbag system malfunction
▷Warning light does not light up in the radio
ready state.▷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 ac‐
cident occurs. ◀
FTM Flat Tire Monitor The concept
The system does not measure the actual infla‐
tion pressure in the tires.
The system detects a pressure loss in a tire by
comparing the rotational speeds of the individ‐
ual 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 correction 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.

Run-flat tiresYou 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.At the next opportunity, check the inflation
pressure in all four tires.
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.
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‐
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 continue driving, and contact your service
center. ◀
Tire Pressure Monitor
TPM
The concept
The system monitors the tire pressure in the
four mounted tires. The system notifies you 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 216.
Functional requirements
The system must have been reset while the in‐
flation pressure was correct; otherwise, it may
not reliably signal a loss in pressure.
Perform a system reset after adjusting the tire
inflation pressure to a new value and after
changing a tire or wheel
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.Seite 86CONTROLSSafety86

▷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 224, are la‐
beled on the tire sidewall with a circular
symbol containing the letters RSC.
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. The tire pressure gauge of the
Mobility System, refer to page 225, can be
used for this purpose.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been reset. Reset 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 225.
Use of tire sealant, e.g., the Mobility Sys‐
tem, may damage the TPM wheel electron‐
ics. In this case, have the electronics
checked at the next opportunity and have
them replaced if necessary.Run-flat tires
You can continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
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. ◀

Message indicating that the inflation
pressure needs to be checked
The yellow warning light lights up.
A Check Control message is displayed.
An additional message is displayed on
the onboard monitor.▷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.
