Protective action
Airbags are not triggered in every impact situa‐
tion, e.g., in less severe accidents or rear-end
collisions.
Information on how to ensure the optimal
protective effect of the airbags▷Keep at a distance from the airbags.▷Always grasp the steering wheel on the
steering wheel rim, holding your hands at
the 3 o'clock and 9 o'clock positions, to keep
the danger of injury to your hands or arms as
low as possible if the airbag is triggered.▷There should be no people, animals, or ob‐
jects between an airbag and a person.▷Do not use the cover of the front airbag on
the front passenger side as a storage area.▷Keep the dashboard and window on the
front passenger side clear, i.e., do not cover
with adhesive labels or coverings, and do not
attach holders such as for navigation instru‐
ments and mobile phones.▷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 and do not rest
against the head airbag; otherwise, injuries
can occur if the airbags are triggered.▷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, the seats, the roof pillars and the
sides of the headliner.◀
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.

Indication of a flat tire The yellow warning lamp lights up. A
Check Control message is displayed.
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 reg‐
ular tires or run-flat tires.
Run-flat tires, refer to page 198, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.
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 flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
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.Actions in the event of a flat tire
Normal tires1.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 Flat Tire 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.
Run-flat tires
Maximum speed
You 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.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.
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.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
