2013 MERCEDES-BENZ CLA COUPE airbag disable

The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen- tially determined by:
R the distribution of forces during the colli-
sion
R the collision angle
R the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a
decisive role in the deployment of an airbag,
nor do they provide an indication of airbag
deployment.
The vehicle may be deformed significantly,
e.g. the bonnet or the wing, without an airbag being deployed. This is the case if only parts
which are relatively easily deformed are affec-ted and the rate of deceleration is not high.
Conversely, airbags may be deployed even
though the vehicle suffers only minor defor-
mation. This is the case if, for example, very
rigid vehicle parts such as longitudinal body
members are hit, and sufficient deceleration
occurs as a result.
i The front belt tensioners can only be trig-
gered if the seat belt tongues on the front
seats are correctly engaged in the seat belt buckles.
i Not all airbags are deployed in an acci-
dent. The different airbag systems work
independently of each other.
How the airbag system works is deter-
mined by predicting the severity of the acci-
dent, especially vehicle deceleration or
acceleration, and the type of accident:
R head-on collision
R side impact
R overturn Airbags
Important safety notes G
WARNING
Airbags provide additional protection; they
are not, however, a substitute for seat belts.
Observe the following notes to reduce the risk of serious or even fatal injury caused by airbag
deployment:
R all vehicle occupants – in particular, preg-
nant women – must wear their seat belt
correctly at all times and lean back against
the backrest, which should be positioned
as close to the vertical as possible. The
head restraint must support the back of the
head at about eye level.
R always secure children less than 1.50 m tall
or under 12 years of age in suitable child
restraint systems.
R all vehicle occupants must select a seat
position that is as far away from the airbag
as possible. The driver's seat position must allow the vehicle to be driven safely. The
driver's chest should be as far away from
the centre of the driver's airbag cover as
possible.
R move the front-passenger seat as far back
as possible. This is especially important if
you have secured a child in a child restraint
system on the front-passenger seat.
R vehicle occupants – in particular, children –
must not lean their head into the area of the
window in which the sidebag/windowbag is deployed.
R rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger airbag has
been disabled. On the front-passenger
seat, the front-passenger airbag is disabled if a child restraint system with a trans-
ponder for automatic child seat recognition
is fitted to the front-passenger seat in a
vehicle equipped with automatic child seat recognition. The 4PASSENGER AIRBAG 42
Occupant safetySafety

The front-passenger front airbag is not disa-
bled:
R on vehicles without automatic child seat
recognition on the front-passenger seat
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat,
unless a child restraint system with trans-
ponders for automatic child seat recogni-
tion is fitted to the front-passenger seat
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat, if the
4 PASSENGER AIRBAG OFF indicator
lamp is not lit.
To make you aware of this danger, a corre-
sponding warning sticker has been affixed to
the side of the dashboard and on both sides of the sun visor on the front-passenger side.
Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre. Warning notice on the front-passenger sun visor
Warning symbol for a rearward-facing child
restraint system NEVER use a rearward facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it, DEATH or SERIOUS INJURY to the
CHILD can occur.
Automatic child seat recognition on the
front-passenger seat G
WARNING
If the 4 PASSENGER AIRBAG OFF indica-
tor lamp does not light up when the child
restraint system is fitted, the front-passenger front airbag has not been disabled. If the front-
passenger front airbag deploys, the child
could be seriously or even fatally injured.
Proceed as follows:
R do not use a rearward-facing child restraint
system on the front-passenger seat.
R fit a rearward-facing child restraint system
on a suitable rear seat.
or R only use a forward-facing child restraint
system on the front-passenger seat and
move the front-passenger seat as far back
as possible. When doing so, ensure that the
shoulder belt strap from the belt outlet on
the vehicle is routed towards the front to
the shoulder belt guide on the child
restraint system. Set the belt height adjust-
ment so that the belt strap is routed
towards the front along the bottom.
R have the automatic child seat recognition
checked at a qualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. a cushion, under the child
restraint system. The entire base of the child
restraint system must always rest on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could lead to injuries. Children in the vehicle

WARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger front airbag could deploy unintentionally or not function as intended
during an accident. This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. If the front-passenger seat of your vehicle is
not equipped with automatic child seat rec-
ognition, this is indicated by a special sticker. The sticker is affixed to the side of the dash-
board on the front-passenger side. The
sticker is visible when you open the front-
passenger door.
Vehicles without automatic child seat recog-
nition on the front-passenger seat: if you turn
the key to position 2in the ignition lock, the
PASSENGER AIRBAG OFF indicator lamp
lights up briefly. However, the indicator lamp
has no function. It does not indicate that there is automatic child seat recognition on the
front-passenger seat. :
PASSENGER AIRBAG OFF indicator lamp
The sensor system for child restraint systems
in the front-passenger seat detects whether a special Mercedes-Benz child seat with a
transponder for automatic child seat recog-
nition has been fitted. In this case,
PASSENGER AIRBAG OFF indicator lamp :
lights up. The front-passenger front airbag is
disabled.
i If the front-passenger front airbag is dis-
abled by the automatic child seat recogni-
tion, the following remain enabled on the
front-passenger side:
R the sidebag
R the windowbag
R the belt tensioner
ISOFIX child seat securing system for
the rear seats G
WARNING
ISOFIX child restraint systems do not offer
sufficient protective effect for children whose weight is greater than 22 kg who are securedusing the safety belt integrated in the child
restraint system. The child could, for example,not be restrained correctly in the event of an
accident. This poses an increased risk of
injury or even fatal injury.
If the child weighs more than 22 kg, only use
ISOFIX child restraint systems with which the child is also secured with the vehicle seat belt. Also secure the child restraint system with the
Top Tether belt, if available. 54

If you use a baby car seat from category 0 or 0+ or a rearward-facing child restraint system from category I
on a rear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch the
rearward-facing child restraint.
2 Vehicles with automatic child seat recognition in the front-passenger seat: a child restraint system from the
"Universal" category with a transponder for automatic child seat recognition must be fitted. The PASSENGER AIRBAG OFF indicator lamp must be lit.
3 Move the front-passenger seat as far back as possible. If you secure a child in a forward-facing child restraint
system on the front-passenger seat, ensure that the shoulder belt strap from the belt outlet on the vehicle is
routed towards the front to the shoulder belt guide on the child restraint system. Set the belt height adjust-
ment so that the belt strap is routed towards the front along the bottom. Move the front-passenger seat to the highest position and move the backrest to an almost vertical position. When doing so, ensure that the com-plete surface of the child restraint system rests against the backrest of the front-passenger seat and that the
child restraint system does not touch the roof. To do so, you may have to adjust the backrest down a little. For seats with electrical adjustment, the seat cushion angle must be set to the highest and most upright position.

Example: approval label on the child restraint system
"Universal" category child restraint systems can be recognised by their orange approval label and the text "Universal".
"Universal" category child restraint systems can be used on the seats indicated with U, UF or
IUF according to the tables "Suitability of the seats for attaching belted child restraint systems"
or "Suitability of the seats for attaching an ISOFIX child restraint system".
Semi-universal child restraint systems are indicated by the text "Semi-universal" on the
approval label. These can be used if the vehicle and the seat are listed in the child restraint
system manufacturer's vehicle model list. For more information, contact the child restraint
system manufacturer or visit their website.
Suitability of the seats for attaching ISOFIX child restraint systems
1 If you use a baby car seat from category 0 or 0+ or a rearward-facing child restraint system from category I
on a rear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch the
rearward-facing child restraint.
3 Move the front-passenger seat as far back as possible. If you secure a child in a forward-facing child restraint
system on the front-passenger seat, ensure that the shoulder belt strap from the belt outlet on the vehicle is routed towards the front to the shoulder belt guide on the child restraint system. Set the belt height adjust-
ment so that the belt strap is routed towards the front along the bottom. Move the front-passenger seat to the
highest position and move the backrest to an almost vertical position. When doing so, ensure that the com- plete surface of the child restraint system rests against the backrest of the front-passenger seat and that thechild restraint system does not touch the roof. To do so, you may have to adjust the backrest down a little. For seats with electrical adjustment, the seat cushion angle must be set to the highest and most upright position.
5 For certain child restraint systems in this weight category, this can mean that the area of use is restricted as
the maximum size setting of the child restraint system is not possible due to possible contact with the roof. 58
