WARNING
The ensure the front-seat passenger air‐
bag function, it must be detected, whether a
person occupies the front passenger seat. The
entire seat cushion area must be used for this
purpose. There is risk of injuries or danger to
life. Make sure that the front passenger keeps
his or her feet in the floor area. ◀
Malfunction of the automatic
deactivation system
When transporting older children and adults,
the front passenger airbags may be deactivated
in certain sitting positions. In this case, the indi‐
cator lamp for the front passenger airbags
lights up.
In this case, change the sitting position so that
the front passenger airbags are activated and
the indicator lamp goes out.
If it is not possible to activate the airbags, have
the person sit in the rear.
To make sure that occupation of the seat cush‐
ion can be detected correctly:▷Do not attach covers, cushions, ball mats or
other items to the front passenger seat un‐
less they are specifically determined to be
safe for use on the front passenger seat.▷Do not place electronic devices on the pas‐
senger seat if a child restraint fixing system
is mounted on the seat.▷Do not place objects under the seat that
could press against the seat from below.Indicator light for the front passenger airbags
The indicator lamp for the front passenger air‐
bags indicates the operating state of the front
passenger airbags.
The light indicates whether the airbags are acti‐
vated or deactivated.
▷The indicator lamp lights up
when a child who is properly
seated in a child restraint fix‐
ing system intended for that
purpose is detected on the
seat or the seat is empty. The
airbags on the front passen‐
ger side are not activated.▷The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient size is detected on the seat. The
airbags on the front passenger side are ac‐
tivated.
Most child seats are detected by the system.
Especially the child seats required by NHTSA at
the time that the vehicle was manufactured.
After installing a child seat, make sure that the
indicator lamp for the front passenger airbags
lights up. This indicates that the child seat has
been detected and the front passenger airbags
are not activated.

Operational readiness of airbag system
Information WARNING
Individual components can be hot after
triggering of the airbag system. There is risk of
injuries. Do not touch individual components. ◀
WARNING
Improperly executed work can lead to
failure, malfunction or unintentional triggering of the airbag system. In the case of a malfunc‐
tion, the airbag system could not trigger as in‐ tended in the event of an accident despite re‐
spective accident severity. There is risk of
injuries or danger to life. Have the airbag sys‐
tem checked, repaired, dismantled and scrap‐
ped by a dealer’s service center or another
qualified service center or repair shop. ◀
Correct function
In the radio ready state and beyond, re‐
fer to page 50, 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.
The airbag restraint system and belt tensioner
are not working. Have the vehicle checked im‐
mediately by a dealer’s service center or an‐
other qualified service center or repair shop.
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
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
Sudden serious tire damage caused by external
influences cannot be indicated in advance.
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.Seite 77SafetyCONTROLS77
Online Edition for Part no. 01 40 2 964 433 - VI/15
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
