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 58, 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 85SafetyCONTROLS85
Online Edition for Part no. 01 40 2 964 459 - VI/15
Low tire pressure messageThe warning lights come on in yellow
and red. A Check Control message is
displayed. A message is displayed on
the onboard monitor. In addition, a sig‐
nal 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 226, 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
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 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 226, 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 identification of flat tire damage is not
possible, please contact a dealer’s service
center or another qualified service center or
repair shop.2.Rectify the flat tire using the Mobility Sys‐
tem, refer to page 226.
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.
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. ◀
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:
Seite 89SafetyCONTROLS89
Online Edition for Part no. 01 40 2 964 459 - VI/15
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.
WARNING
Your vehicle handles differently when a
run-flat tire is damaged and has low or missing
tire inflation pressure, e.g., your lane stability is
reduced when braking, braking distances are
longer and the self-steering properties will
change. There is risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h. ◀
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.An additional message is displayed on the on‐
board 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.
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.
An additional message is displayed on
the onboard monitor.
A flat tire or tire inflation pressure loss cannot
be detected.

Driving stability control systemsVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems.
When using the features and systems described
here, adhere to local regulations.
Antilock Brake System
ABS
ABS prevents locking of the wheels during braking.
Steerability is maintained even during full brak‐ ing. This increases active driving safety.
ABS is operational every time you start the en‐
gine.
Electronic brake-force distribution EBVThe system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
CBC Cornering Brake Control When braking in curves or during a lane
change, driving stability and steering response
are improved further.
Brake assistant
When the brakes are applied rapidly, this sys‐
tem automatically produces the maximum
braking force boost. In this way, the system
helps keep the braking distance as short aspossible. This system utilizes all of the benefits
provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of full braking.
Dynamic Stability Con‐
trol DSC
The concept
DSC prevents traction loss in the driving wheels
when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes to the individual
wheels.
Adapt your driving style to the situation, for an
appropriate driving style is always the responsi‐
bility of the driver.
DSC is operational every time you start the en‐
gine.
WARNING
When driving with roof load, e.g. with
roof-mounted luggage rack, driving safety may
not be ensured in driving-critical situations due
to the elevated center of gravity. There is risk of
accidents or risk of property damage. Do not
deactivate Dynamic Stability Control DSC when
driving with roof load. ◀Seite 93Driving stability control systemsCONTROLS93
