OCS is malfunctioning.
XMake sure there is nothing between the seat cushion and the
child seat.
XMake sure that the entire base of the child restraint system rests
on the seat cushion of the front-passenger seat. The backrest of
the forward-facing child restraint system must lie as flat as
possible against the backrest of the front-passenger seat. If
necessary, adjust the position of the front-passenger seat.
XWhen installing the child restraint system, make sure that the
seat belt is tight. Do not pull the seat belt tight using the front-
passenger seat adjustment. This could result in the seat belt and
the child restraint system being pulled too tightly.
XCheck for correct installation of the child restraint system.
XMake sure that no objects are applying additional weight onto
the seat.
XIf the PASSENGER AIR BAG OFF indicator lamp remains off and/or
the PASSENGER AIR BAG ON indicator lamp lights up, do not
install a child restraint system on the front-passenger seat.
XHave the OCS checked at a smart center as soon as possible.
Deployment of belt tensioners and air
bags
Important safety notes
GWARNING
The air bag parts are hot after an air bag
has been deployed. There is a risk of
injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified
specialist workshop as soon as possible.
GWARNING
A deployed air bag no longer offers any
protection and cannot provide the intended
protection in an accident. There is an
increased risk of injury.
Have the vehicle towed to a qualified spe-
cialist workshop in order to have a
deployed air bag replaced.
For your own safety and that of your front
passenger, it is important that you have
deployed air bags replaced and faulty air
bags repaired. This will help to make sure the
air bags continue to perform their protective
function for the vehicle occupants in the
event of a crash.

heat or cold, there is a risk of injury, pos-
sibly even fatal. Never leave children
unattended in the vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot.
Children may burn themselves on these
parts, particularly on the metal parts of the
child restraint system. There is a risk of
injury.
If you leave the vehicle, taking the child
with you, always ensure that the child
restraint system is not exposed to direct
sunlight. Protect it with a blanket, for
example. If the child restraint system has
been exposed to direct sunlight, let it cool
down before securing the child in it. Never
leave children unattended in the vehicle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are
sitting properly. Particular attention must
be paid to children.
Read and follow the safety notes on the seat
belt (
Ypage 31) and the notes on correct use of
the seat belts (Ypage 32).
A booster seat may be necessary to achieve
proper seat belt positioning for children
over 41 lbs (18 kg) until they reach a height
where a lap/shoulder belt fits properly with-
out a booster seat.
Special seat belt retractor
GWARNING
If the seat belt is released while driving,
the child restraint system will no longer be
secured properly. The special seat belt
retractor is disabled and the inertia real
draws in a portion of the seat belt. The seat belt cannot be immediately refastened.
There is an increased risk of injury, pos-
sibly even fatal.
Stop the vehicle immediately, paying
attention to road and traffic conditions.
Reactivate the special seat belt retractor
and secure the child restraint system prop-erly.
The seat belt on the front-passenger side is
equipped with a special seat belt retractor.
When activated, the special seat belt retrac-
tor ensures that the seat belt will not slacken once the child restraint system has been
secured.
Installing a child restraint system:
XAlways comply with the child restraint sys-
tem manufacturer's installation instruc-
tions.
XPull the seat belt smoothly from the belt
loop.
XEngage the seat belt tongue in the belt
buckle.
Activating the special seat belt retractor:
XPull the seat belt out fully and let the seat
belt retractor retract it again.
While the seat belt is retracting, you
should hear a ratcheting sound. The special seat belt retractor is activated.
XPress the child restraint system down so
that the seat belt fits tightly and does not
slacken.
Removing a child restraint system and deac-
tivating the special seat belt retractor:
XAlways comply with the child restraint sys-
tem manufacturer's installation instruc-
tions.
XPress the seat belt buckle release button,
hold the belt tongue firmly and guide it
back towards the belt outlet.
The special seat belt retractor is deacti-
vated.

GWARNING
If the child restraint system is installed
incorrectly on a suitable seat, it cannot
protect as intended. The child cannot then
be restrained in the event of an accident,
heavy braking or sudden changes of direc-
tion. There is an increased risk of injury,
possibly even fatal.
Make sure that you observe the child
restraint system manufacturer's installa-
tion instructions and the notes on use.
Please ensure, that the base of the child
restraint system is always resting com-
pletely on the seat cushion. Never place
objects, e.g. cushions, under or behind the
child restraint system. Only use child
restraint systems with the original cover
designed for them. Only replace damaged
covers with genuine covers.
GWARNING
If the child restraint system is installed
incorrectly or is not secured, it can come
loose in the event of an accident, heavy
braking or a sudden change in direction.
The child restraint system could be thrown
about, striking vehicle occupants. There is an increased risk of injury, possibly even
fatal.
Always install child restraint systems
properly, even if they are not being used.
Make sure that you observe the child
restraint system manufacturer's installa-
tion instructions.
You will find further information on stowing
objects, luggage or loads under "Loading
guidelines" (
Ypage 142).
GWARNING
Child restraint systems or their securing
systems which have been damaged or sub-
jected to a load in an accident can no longer protect as intended. The child cannot then
be restrained in the event of an accident,
heavy braking or sudden changes of direc-
tion. There is an increased risk of injury,
possibly even fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the
securing systems on the child restraint
system checked at a qualified specialist
workshop, before you install a child
restraint system again.
Securing systems for child restraint systems
include:
Rthe seat belt system
Rthe Top Tether anchorages
iIf you install a child restraint system on
the front-passenger seat, make sure that
the backrest is securely engaged
(
Ypage 63).
iIf a child is carried on the front-
passenger seat, be sure to observe the
information on "Child restraint systems on
the front-passenger seat" (
Ypage 45).
There you will also find information on
disabling the front-passenger front air-
bag.
All child restraint systems must meet the fol-
lowing standards:
RU.S. Federal Motor Vehicle Safety Stand-
ards 213 and 225
RCanadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system
corresponds to the standards can be found on
an instruction label on the child restraint
system. This confirmation can also be found
in the installation instructions that are
included with the child restraint system.
Observe the warning labels in the vehicle
interior and on the child restraint system.

Starting at a speed of around 4 mph (7 km/h),
the distance warning function warns you if
you rapidly approach a vehicle in front. An
intermittent warning tone will then sound
and the 00BAdistance warning lamp will
light up in the instrument cluster.
XBrake immediately in order to increase the distance from the vehicle in front.
or
XTake evasive action, provided it is safe to
do so.
Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause the system to display a
warning.
With the help of the radar sensor system, the
distance warning function can detect obsta-
cles that are in the path of your vehicle for an
extended period of time.
Up to a speed of around 45 mph (70 km/h), the
distance warning function can also react to
stationary obstacles, such as stopped or
parked vehicles.
