General information DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of the
vehicle. There is danger to life. Keep the ex‐
haust pipe free and ensure sufficient ventila‐
tion. ◀

Knee airbagThe knee airbag supports the legs in a frontal
impact.
Protective action Airbags are not triggered in every impact situa‐
tion, e.g., in less severe accidents or rear-end
collisions.
Information for optimum effect of the
airbags
WARNING
If the seat position is incorrect or the de‐
ployment area of the airbags is impacted, the
airbag system cannot protect as intended or
cause additional injuries due to triggering.
There is risk of injuries or danger to life. Follow
the information on optimum protective effect
of the airbag system. ◀▷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 trig‐
gered.▷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 or cables such as for
navigation instruments 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 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 hang pieces of clothing, such as
jackets, 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.
Warning notices and information about the air‐
bags can also be found on the sun visors.
Automatic deactivation of the front
passenger airbags
The system determines whether the front pas‐
senger seat is occupied by measuring the elec‐
trical resistance of the human body.
The front, side, and knee airbags on the front
passenger side are activated or deactivated ac‐
cordingly by the system.
The indicator lamp above the interior rearview
mirror, refer to page 76, shows the current
status of the front passenger airbags, deacti‐
vated or activated.
Before transporting a child on the front passen‐
ger seat, read the safety and operating instruc‐
tions under Transporting children safely, refer
to page 45.

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

center or another qualified service center or
repair shop.2.Rectify the flat tire using the Mobility Sys‐
tem, refer to page 162.
Run-flat tires
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.At the next opportunity, check the inflation
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.
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 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 a tire. Reduce speed and
stop, otherwise, pieces of the tire could come
loose and cause an accident. Do not continue
driving. Contact a dealer’s service center or an‐
other qualified service center or repair shop.
Tire Pressure Monitor
TPM
The concept
The system monitors the tire pressure in the
four mounted tires. The system notifies you if
there is a significant loss of pressure in one or
more tires. Sensors in the tire valves measure
the tire pressure.
Information
To operate the system, also note the additional
information and instructions contained under
Tire inflation pressure, refer to page 154.
Functional requirements
The system must have been reset while the in‐
flation pressure was correct; otherwise, it may
not reliably signal a loss in pressure.
Perform a system reset after adjusting the tire
inflation pressure to a new value and after
changing a tire or wheel
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.Seite 79SafetyCONTROLS79
