Problems with automatic child seat recognition
Problem
Possible causes/consequences and
M
MSolutions The PASSENGER AIR-
BAG OFF indicator
lamp on the centre con-
sole is lit. A special Mercedes-Benz child seat with a transponder for auto-
matic child seat recognition has been fitted to the front-passenger
seat. The front-passenger front airbag has therefore been disabled
as desired. G
WARNING
There is no child seat fitted to the front-passenger seat. Automatic child seat recognition is malfunctioning.
When you switch on the ignition, it is also possible that:
R the 6 SRS warning lamp lights up.
R the PASSENGER AIRBAG OFF indicator lamp does not light up
briefly.
R the PASSENGER AIRBAG ON indicator lamp does not light up, or
lights up and does not go out after 60 seconds.
There is a risk of injury.
X Remove electronic equipment from the front-passenger seat,
e.g.:
R laptop
R mobile phone
R cards with transponders, such as ski passes or access cards
If the PASSENGER AIRBAG OFF indicator lamp is still lit: X Visit a qualified specialist workshop. Driving safety systems

If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of an accident nor
override the laws of physics. Driving safety
systems are merely aids designed to assist
driving. You are responsible for the distance

WARNING
When the double locks are activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
If the vehicle has been locked from the out-
side, the double-lock function is activated as
standard. It is then not possible to open the
doors from inside the vehicle. You can deac-
tivate the double-lock function by deactivat-
ing the interior motion sensor (Y page 80).
The doors can then be opened from the inside after the vehicle has been locked from the
outside. The anti-theft alarm system is trig- gered if the door is opened from the inside.

If children adjust the seats, they could
become trapped, especially if they are unat-
tended. There is a risk of injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If the driver's seat is not engaged, it can move unexpectedly while the vehicle is in motion.
This could cause you to lose control of the
vehicle. There is a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the engine. G
WARNING
If you adjust the seat height carelessly, you or other vehicle occupants could be trapped andthereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem. G
WARNING
When adjusting a seat, you or another vehicle occupant could become trapped by the guiderail of the seat, for instance. There is a risk of
injury.
Make sure that no one has any part of their
body within the sweep of the seat when
adjusting it. G
WARNING
The head restraints cannot provide the inten-
ded protection unless they are fitted and
adjusted correctly. There is an increased risk of injury to the head and neck in the event of
an accident or sudden braking, for example.
Always drive with the head restraints fitted.
Ensure that the centre of the head restraints
support the back of each vehicle occupant's
head at eye level before driving off. G

driving if you:
R adjust the driver's seat, steering wheel or
mirror
R fasten the seat belt.
There is a risk of an accident.
Adjust the driver's seat, steering wheel or
mirror and fasten the seat belt before starting
the engine.
! To avoid damage to the seats and the seat
heating, observe the following information:
R do not spill any liquids on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools. The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate- rials, e.g. blankets, coats, bags, seat cov-
ers, child seats or booster seats. Seats

airbags could cause additional injuries to
vehicle occupants in the front. There is an

as far away as possible from the front airbags.
In addition, observe the instructions on how to
adjust the seats correctly.
