Seats, restraints49Airbag system
The airbag system consists of a
number of individual systems
depending on the scope of
equipment.
When triggered, the airbags inflate
within milliseconds. They also deflate
so quickly that it is often unnoticeable during the collision.9 Warning
The airbag system deploys in an
explosive manner, repairs must be performed by skilled personnel
only.
9 Warning
Adding accessories that change
the vehicle's frame, bumper
system, height, front end or side
sheet metal, may keep the airbag
system from working properly. The operation of the airbag system can
also be affected by changing any
parts of the front seats, seat belts,
airbag sensing and diagnostic
module, steering wheel,
instrument panel, inner door seals including the speakers, any of the
airbag modules, ceiling or pillar
trim, front sensors, side impact
sensors or airbag wiring.
Note
The airbag systems and belt
pretensioner control electronics are
located in the centre console area.
Do not put any magnetic objects in
this area.
Do not affix any objects onto the
airbag covers and do not cover them with other materials. Have damagedcovers replaced by a workshop.
Each airbag is triggered only once.
Have deployed airbags replaced by
a workshop. Furthermore, it may be
necessary to have the steering
wheel, the instrument panel, parts of
the panelling, the door seals,
handles and the seats replaced.
Do not make any modifications to
the airbag system as this will
invalidate the vehicle operating
permit.

54Seats, restraintsAirbag deactivation
The front passenger airbag system
must be deactivated for child restraint system on the passenger seat
according to the instructions in the
table 3 58. The side airbag and
curtain airbag systems, the belt
pretensioners and all driver airbag
systems will remain active.
The front passenger airbag system
can be deactivated via a key-
operated switch on the passenger side of the instrument panel.
Change status only when the vehicle is stopped with the ignition off.
Switch positions:* OFF:front passenger airbag is
deactivated and will not
inflate in the event of a
collision. Control indicator
* OFF illuminates
continuously in the centre
consoleÓ ON:front passenger airbag is
active9 Danger
Deactivate passenger airbag only
in combination with the use of a
child restraint system, subject to
the instructions and restrictions in
the table 3 58.
Otherwise, there is a risk of fatal
injury for a person occupying a
seat with a deactivated front
passenger airbag.If the control indicator ÓON
illuminates for approx. 60 seconds
after the ignition is switched on, the
front passenger airbag system will
inflate in the event of a collision.
If the control indicator *OFF
illuminates after the ignition is
switched on, the front passenger
airbag system is deactivated. It stays
on while the airbag is deactivated.
If both control indicators are
illuminated at the same time, there is
a system failure. The status of the
system is not discernible, therefore
no person is allowed to occupy the
front passenger seat. Contact a
workshop immediately.

148Driving and operatingA precondition is that forward collision
alert with front camera system is not
deactivated in the vehicle
personalisation menu 3 95.
The system includes: ● emergency automatic braking● forward looking brake assist
● forward collision alert
● front pedestrian protection
Emergency automatic braking
After activation of brake preparation
system and just before the imminent
collision, this function automatically
applies limited braking to reduce the
impact speed of the collision or
prohibit a crash. If active emergency
braking is applied, m flashes in the
instrument cluster. Depending on the
situation, the vehicle may
automatically brake moderately or
hard. This front automatic braking can
only occur if a vehicle or a pedestrian
ahead is detected.
Forward collision alert 3 145
Front pedestrian protection 3 149Emergency automatic braking may
slow the vehicle to a complete stop to
try to avoid a potential crash.9 Warning
Emergency automatic braking is
an emergency crash preparation
feature and is not designed to
avoid crashes. Do not rely on the
system to brake the vehicle.
Emergency automatic braking will
not brake outside of its operating speed range and only responds to
detected vehicles and
pedestrians.
Forward looking brake assist
In addition to emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. Therefore, pressing
the brake pedal less strongly results in immediate hard braking. This
function helps the driver brake
quicker and harder before the
imminent collision.
9 Warning
Active emergency braking is not
designed to apply hard
autonomous braking or to
automatically avoid a collision. It is designed to reduce the vehicle
speed before a collision. It may not
react to animals. After a sudden
lane change, the system needs a
certain time to detect the next
preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the brakes and steer to avoid
collisions.
The system is designed to work with
all occupants wearing their seat belts.

Front pedestrian protection 3 149.
