Airbags
1Front airbag, driver2Front airbag, front passenger3Head airbag4Side airbag5Knee airbagFront airbags
Front airbags help protect the driver and front
passenger by responding to frontal impacts in
which safety belts alone would not provide ad‐
equate restraint.Side airbag
In a lateral impact, the side airbag supports the
side of the body in the chest and lap area.
Head airbag
In a lateral impact, the head airbag supports
the head.Seite 99SafetyCONTROLS99

Ejection MitigationThe head airbag system is designed as an ejec‐
tion mitigation countermeasure to reduce the
likelihood of ejections of vehicle occupants
through side windows during rollovers or side
impact events.
Knee airbag
The 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. Ob‐
serve the Information for optimum protective
effect of the airbag system. ◀▷Keep at a distance from the airbags.▷Make sure that occupants keep their heads
away from the side airbag.▷Always grasp the steering wheel on the
steering wheel rim. Hold your hands at the
3 o'clock and 9 o'clock positions, to keep
the risk of injury to your hands or arms as
low as possible when the airbag is trig‐
gered.▷Make sure that the front passenger is sitting
correctly, i.e., keeps his or her feet and legs
in the floor area.▷There should be no persons, animals or ob‐
jects between an airbag and a person.▷Do not apply adhesive materials to the air‐
bag cover panels, do not cover them or
modify them in any way.▷Dashboard and windshield on the front
passenger side must stay clear - do not at‐
tach adhesive labels or coverings and do
not attach brackets or cables, e. g., for GPS
devices or' mobile phones.▷Do not use the cover of the front airbag on
the front passenger side as a storage area.▷Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not specifically suited for seats with
integrated side airbags.▷Do not hang pieces of clothing, such as
jackets, over the backrests.▷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.▷Do not remove the airbag system.
Even when you follow all instructions very
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.
Warnings and information on the airbags are
also found on the sun visors.
Functional readiness of the 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 When the ignition is switched on, the
warning lamp in the instrument cluster
lights up briefly and thereby indicates
the operational readiness of the entire airbag
system and the belt tensioner.
Airbag system malfunctioning▷Warning lamp does not come on when the
ignition is turned on.▷The warning lamp lights up continuously.
Automatic deactivation of the front-
seat passenger airbags
The concept
The system reads if the front passenger seat is
occupied by measuring the human body's re‐
sistance.
Front, knee and side airbag on the front pas‐
senger's side are either activated or deacti‐
vated.
Information Before transporting a child on the front passen‐
ger seat, refer to the safety notes and instruc‐
tions for children on the front passenger seat,
see Children.
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-seat passenger airbags may be deac‐
tivated in certain sitting positions. In this case,
the indicator lamp for the front-seat passenger
airbags lights up.
In this case, change the sitting position so that
the front-seat 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 enable correct recognition of the occupied
seat cushion▷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 any electronic devices on the
passenger seat if a child restraint system is
to be installed on it.▷Do not place objects under the seat that
could press against the seat from below.▷No moisture in or on the seat.
Indicator lamp for the front-seat
passenger airbags
The indicator lamp for the front-seat passenger
airbags indicates the operating state of the
front-seat passenger airbags.
Seite 101SafetyCONTROLS101

The lamp indicates whether the airbags are ei‐
ther activated or deactivated.▷The indicator lamp lights up
when a child is properly
seated in a child restraint fix‐
ing system or when the seat
is empty. The airbags on the
front passenger side are not
activated.▷The indicator lamp does not light up when,
e.g., a correctly seated person of sufficient
size is detected on the seat. The airbags on
the front passenger side are activated.
Detected child seats
The system generally detects children seated in
a child seat, particularly in child seats required
by NHTSA when the vehicle was manufactured.
After installing a child seat, make sure that the
indicator lamp for the front-seat passenger air‐
bags lights up. This indicates that the child seat
has been detected and the front-seat passen‐
ger airbags are not activated.
Strength of the driver's and front-seat
passenger airbag
The explosive power that activates driver's/
front passenger's airbags very much depends
on the positions of the driver's/front passeng‐
er's seat.
To maintain the accuracy of this function over
the long-term, calibrate the front seats as soon
as a relevant Check Control message is dis‐
played. A message also appears on the Control
Display.
Calibrating the front seats WARNING
There is risk of jamming when moving the
seats. There is risk of injuries or risk of property
damage. Make sure that the area of movement
of the seat is clear prior to any adjustment. ◀
An appropriate Check Control message is dis‐
played.1.Move the respective seat all the way for‐
ward.2.Move the respective seat forward again. It
moves forward briefly.3.Readjust the seat to the desired position.
The calibration procedure is completed when
the Check Control message disappears.
If the message continues to be displayed, re‐
peat the calibration.
If the message does not disappear after a re‐
peat calibration, have the system checked as
soon as possible.
Tire Pressure Monitor
TPM
The concept
The system monitors tire inflation pressure in the four mounted tires. The system warns you if
there is a significant loss of pressure in one or
more tires. For this purpose, sensors in the tire
valves measure the tire inflation pressure.
Information With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 178.
Functional requirements The system must have been reset with the cor‐
rect tire inflation pressure; otherwise, reliable
signaling of tire pressure loss is not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.

short period, the set tire inflation pressures are
accepted as reference values. The resetting
process is completed automatically while driv‐
ing. After successful completion of the reset,
the tires appear in green on the Control Display
and "Tire Pressure Monitor (TPM) active" is dis‐ played.
The progress of the reset is displayed.
You may interrupt this trip at any time. When
you continue the reset resumes automatically.
Low tire pressure message 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.▷A reset of the system was not carried out
after a wheel was changed. The system
therefore issues a warning based on the tire
pressures before the last reset.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 187, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.Seite 103SafetyCONTROLS103
Online Edition for Part no. 01 40 2 963 334 - VI/15
Page 104 of 246

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. Ob‐
serve the information on run-flat tires and con‐
tinued driving with these tires. ◀
A low tire inflation pressure might turn on DSC
Dynamic Stability Control.
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.
The tire pressure gauge of the Mobility Sys‐
tem, refer to page 188, 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 initialized. In this case, initialize
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.Fix the flat tire using the Mobility System,
refer to page 188.
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 replaced if needed.
Run-flat tires Maximum speed
You may 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
shown to be correct, it is possible that the
Tire Pressure Monitor did not perform a re‐
set. Then perform the reset.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on cargo load, driv‐
ing style and road conditions.
A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
A vehicle with a damaged tire reacts differently,
e.g., it has reduced lane stability during brak‐
ing, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering ma‐
neuvers or driving 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 shorter or longer 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. ◀
