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.

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

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

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‐

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.

Declaration according to NHTSA/FMVSS
138 Tire Pressure Monitoring Systems
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label (If your
vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi‐
mately one minute and then remain continu‐
ously illuminated. This sequence will continue
upon subsequent vehicle startups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installation of re‐
placement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Speed limit
The concept
Enter a speed for which a Check Control mes‐
sage will be displayed when the speed is
reached. This enables you to receive warnings if
you exceed a speed limit in an urban area, for
example.
You are only warned of reaching this speed a
second time if your vehicle speed falls below it
again by at least 3 mph/5 km/h.Seite 91SafetyCONTROLS91

Intervening measures to stabilize the vehicle
and give it forward momentum are no longer
executed.
When driving with snow chains or to rock the
vehicle free of snow, it may be useful to deacti‐
vate DSC temporarily.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the switch again; the DSC indicator lamps
in the display elements go out.
Indicator/warning lights The indicator lamp in the tachometer
flashes: DSC is controlling the drive
forces and brake forces.

Dynamic Traction Con‐
trol DTC
The concept
The DTC system is a version of the DSC in which
forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
▷When driving in sand, on snowy inclines, in
slush, or on unplowed, snow-covered road
surfaces.▷When rocking a vehicle free or starting off
in deep snow, sand, or on loose ground.▷When driving with snow chains.Seite 94CONTROLSDriving stability control systems94
