▷
Make sure that the front passenger is sitting
correctly, i.e., keeps his or her feet and legs
in the footwell; otherwise, leg injuries can
occur if the front airbag is triggered.
▷ Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not approved specifically for seats
with integrated side airbags.
▷ Do not hang pieces of clothing, such as jack‐
ets, over the backrests.
▷ Make sure that occupants keep their heads
away from the side airbag; otherwise, inju‐
ries can occur if the airbags are deployed.
▷ Do not remove the airbag restraint system.
▷ Do not remove the steering wheel.
▷ Do not apply adhesive materials to the air‐
bag cover panels, cover them or modify
them in any way.
▷ Never modify either the individual compo‐
nents
or the wiring in the airbag system. This
also applies to steering wheel covers, the
dashboard, and the seats.◀
Even when all instructions are followed closely,
injury from contact with the airbags cannot be
ruled out in certain situations.
The ignition and inflation noise may lead to
short-term

and, in most cases, temporary hear‐
ing impairment in sensitive individuals.
In the case of a malfunction, deactivation
and after triggering of the airbags
Do not touch the individual components imme‐
diately after the system has been triggered; oth‐
erwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
your service center or a workshop that has the
necessary authorization for handling explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or un‐
desired triggering of the airbag, either of which
could result in injury.◀
Warnings and information on the airbags are
also found on the sun visors. Functional readiness of the airbag
system
When

the ignition is switch on, the warn‐
ing lamp in the instrument cluster lights
up briefly and thereby indicates the op‐
erational readiness of the entire airbag system
and the belt tensioner.
Airbag system malfunctioning
▷ In radio ready state, the warning lamp does
not come on.
▷ The warning lamp lights up continuously.
When there is a malfunction, have the air‐
bag system checked immediately
When there is a malfunction, have the airbag
system checked immediately; otherwise, there
is

a risk that the system does not function as ex‐
pected in the event of an accident despite cor‐
responding severity of the accident.◀
Automatic deactivation of the front
passenger airbags
The system determines whether the front pas‐
senger seat is occupied by measuring the re‐
sistance of the human body.
The front, knee, and side airbag on the front
passenger side are activated or deactivated ac‐
cordingly.
Leave feet in the footwell
Make sure that the front passenger keeps
his or her feet in the footwell; otherwise, the front
passenger airbags may not function properly.◀

Rollover protection system
The concept
The
rollover protection system is activated dur‐
ing an accident or a critical driving situation,
when there is extreme tilt with respect to the
longitudinal axis or when there is loss of ground
contact. The safety frames located behind the
rear headrests extend within fractions of a sec‐
ond.
In addition to the rollover bracket integrated in
the front windshield frame, the rollover protec‐
tion system guarantees the required head clear‐
ance of all vehicle occupants.
Maintaining movement space
Always keep the movement space of the
rollover protection system clear. Otherwise,
there may be damage or injuries when the roll‐
over protection system is triggered.◀
In less severe accidents, the secured safety belt
and, depending on the severity of the accident,
the belt tensioner and airbag restraint system
provide protection.
Triggered rollover protection system
After deployment or damage
After deployment of the rollover protec‐
tion system or in the event of damage, have the
system checked and replaced.
Have this work performed only by your service
center; otherwise, it cannot be ensured that this
safety feature will function properly.◀
Do not move convertible top
When the rollover protection system is ex‐
tended, do not move the convertible top. Oth‐
erwise, damages or injuries may result.◀
If the rollover protection system was not placed
under any stress after an automatic triggering, it
can be pushed back by hand, e.g. to close the
convertible top. Three people are necessary for
this. 1.
Push the lever to the side and hold it in this
position. 2.
Push down the safety frame.
3. Release lever.
4. Hold down the safety frame.
5. Proceed likewise with the second safety
frame.
6. Close the convertible top
In the event of malfunctions, deactivation
or after deployment
Only have the airbags checked, repaired or dis‐
mantled

and the system scrapped by your serv‐
ice center. Non-professional attempts to service
the system could lead to failure in an emergency
or undesired triggering of the airbag, either of
which could result in injury.◀
Malfunction
A Check Control message is displayed
when there is a malfunction.
Tire Pressure Monitor TPM*
The concept
The tire inflation pressure is measured in the
four mounted tires. The system notifies you if
there is a significant loss of pressure in one or
more tires.
Functional requirements
The system must have been reset when the in‐
flation pressure was correct; otherwise, reliable
signaling of a flat tire is not ensured. Always use
wheels with TPM electronics to ensure that the Seite 91

Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
The system does not operate correctly if it has
not been reset. For example, a flat tire may be
indicated despite correct tire inflation pres‐
sures.
The

For Canadian models: additional
information
The status display additionally shows the cur‐
rent tire inflation pressures and tire tempera‐
tures.
When correcting the tire inflation pressures,
note the following:
The tire pressure increases as the tire temper‐
ature increases.
Therefore, only correct the tire inflation pres‐
sure

when the tire is at the ambient temperature.
Compare the displayed tire temperature with
the external temperature in the instrument clus‐
ter.

1. Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.
2. Check whether the vehicle is fitted with reg‐
ular tires* or run-flat tires*.
Run-flat

tires, refer to page 234, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.
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.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not have been initialized. In this case, initialize
the system.
If an identification is not possible, please
contact the service center.
2. Rectify the flat tire.
Use

of tire sealant, e.g., the Mobility System,
may damage the TPM wheel electronics. In
this case, have the electronics checked at
the next opportunity and have them re‐
placed 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.◀
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 Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure 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 approx. 50 miles/
80 km. Seite 93

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 con‐
tinue driving, and contact your service center.◀
Message when the system was not
reset
A Check Control message is displayed.
The system detected a wheel change but was
not reset.
Warnings regarding the current tire inflation
pressure are not reliable.
Check the tire inflation pressure and reset the
system.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire can be detected.
Display in the following situations: ▷
A wheel without TPM electronics is fitted:
have
the service center check it if necessary.
▷ Malfunction: have the system checked by
your service center.
▷ TPM could not be fully reset. Reset the sys‐
tem again.
▷ Disturbance by systems or devices with the
same

radio frequency: after leaving the area
of the disturbance, the system automatically
becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
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 la‐
bel, you should determine the proper tire infla‐
tion pressure for those tires.) As an added safety
feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that il‐
luminates a low tire pressure telltale when one
or more of your tires is significantly under-in‐
flated. 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 pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping
ability. Please note that the TPMS is not a sub‐
stitute 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 prop‐
erly. The TPMS malfunction indicator is com‐
bined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will
flash for approximately one minute and then re‐

Safety

main continuously illuminated. This sequence
will
continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the mal‐
function indicator is illuminated, the system may
not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for
a variety of reasons, including the installation of
replacement 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.
FTM Flat Tire Monitor*
The concept
The 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; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize 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 can‐
not be detected. Therefore, check the tire infla‐
tion 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 inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming the inflation pressures.
Do not initialize the system when driving with
snow chains*.
