2016 MERCEDES-BENZ C-CLASS CABRIOLET ECU

Vehicles without automatic co-driver's
front airbag deactivation system If the co-driver's seat of your vehicle is not
equipped with an automatic co-driver's front air-
bag deactivation system, this is indicated by a
special sticker. The sticker is affixed to the side of the dashboard on the co-driver's side. The
sticker is visible when you open the co-driver's
door.
Never fit a rearward-facing child restraint sys-
tem to the co-driver's seat in this case
(Y page 62).
Observe the following information under "Rear-
ward-facing child restraint system"
(Y page 62) and "Forward-facing child
restraint system" (Y page 62) and on suitable
positioning of the child restraint system
(Y page 62).
Rearward-facing child restraint system If it is absolutely necessary to fit a rearward-
facing child restraint system to the co-driver's
seat, you must always make sure that the co-
driver's front airbag is deactivated. The co-driv-
er's front airbag is only disabled if the
PASSENGER AIRBAG OFF indicator lamp is lit
continuously (Y page 43).
Always observe the information about suitable
positioning of the child restraint system
(Y page 62) as well as the child restraint sys-
tem manufacturer's installation and operating
instructions.
Forward-facing child restraint system If it is absolutely necessary to secure a child in a
forward-facing child restraint system on the co- driver's seat, you must always move the co-driv-
er's seat as far back as possible. Fully retract the
seat cushion length. The base of the child restraint system must lie fully on the co-driver's
seat cushion. The backrest of the child restraint
system must lie as flat against the co-driver's
seat backrest as possible. The child restraint
system may not touch the roof or be put under
strain by the head restraint. Adjust the angle of
the seat backrest and the head restraint posi-
tion accordingly. Always make sure that the
shoulder belt strap is correctly routed from the
vehicle belt sash guide to the shoulder belt
guide on the child restraint system. The shoul-
der belt strap must be routed forwards and
downwards from the vehicle belt outlet. If nec-
essary, adjust the vehicle belt sash guide and
the co-driver's seat accordingly.
Always observe the information about suitable
positioning of the child restraint system
(Y page 62) as well as the child restraint sys-
tem manufacturer's installation and operating
instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems that are approved in
accordance with ECE standard ECE R44 are per-
mitted for use in the vehicle.
"Universal"-category child restraint systems can be recognised by their orange approval label and
the text "Universal". Example: approval label on the child restraint
system
The following "Universal"-category child
restraint systems can be used on seats labelled
U, UF or IUF according to the tables "Suitability
of the seats for attaching a belt-secured child
restraint system" or "Suitability of the seats for
attaching an ISOFIX child restraint system". 62
Children in the vehicleSafety

Semi-universal child restraint systems are indi-
cated 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 sys-
tem manufacturer's vehicle model list. For fur-
ther information, contact the child restraint sys- tem manufacturer or visit the manufacturer's
website.
If circumstances require you to fit a child
restraint system on the front-passenger seat:
X Always observe the notes under "Child
restraint system on the front-passenger seat"
(Y page 61).
There you will find instructions on how to cor- rectly route the shoulder belt strap from the
vehicle belt outlet to the shoulder belt guide
on the child restraint system (Y page 62).
X Move the front-passenger seat as far back as
possible and fully retract the seat cushion
length. X
Move the backrest to an almost vertical posi-
tion.
The entire base of the child restraint system
must always rest on the seat cushion of the
front-passenger seat. The backrest of the
forward-facing child restraint system must, as far as possible, be resting on the backrest of
the front-passenger seat. The child restraint
system must not touch the roof or be put
under strain by the head restraint. Adjust the angle of the seat backrest and the head
restraint position accordingly. In addition,
observe the child restraint system manufac-
turer's installation instructions.
X Move the seat cushion angle to the highest,
most vertical position.
Suitability of the seats for attaching a belt-secured child restraint system If you use a baby car seat of category 0 or 0+ or a rearward-facing child restraint system of category
I on a rear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch the child restraint system.
Make sure that the child's feet do not touch the front seat. If necessary, move the front seat forwards
slightly.
For certain child restraint systems in weight categories II or III, this can mean that the area of use is restricted. The maximum size setting of the child restraint system may not be possible due to
possible contact with the roof.
When the soft top is opened and closed, child restraint systems of weight categories II or III must be
removed or the head restraint of the child restraint system must be set to the lowest position.
You can have the head restraints of the rear seats removed and installed by a qualified specialist
workshop. This may be necessary for the use of certain child restraint systems.
In addition, always observe the notes under "Child restraint system" (Y page 60) and the child
restraint system manufacturer's installation instructions.

gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the boot
lid is open when the engine is running, espe-
cially if the vehicle is in motion. There is a risk of poisoning.
Always switch off the engine before opening
the boot lid. Never drive with the boot lid
open. G
WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, especially when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
! The boot lid swings upwards when opened.
Therefore, make sure that there is sufficient
clearance above the boot lid.

AIRCAP has the following components:
R a wind deflector above the windscreen
R a draught stop behind the two rear-seat head
restraints
When AIRCAP has been activated, the draught
stop extends up between the two rear-seat head
restraints. At the same time, the wind deflector
extends out along the front windscreen.
AIRCAP can be activated or deactivated up to
speeds of approximately 160 km/h.
Activating and deactivating AIRCAP X
Turn the key to position 2in the ignition lock.
X To activate: pull switch:.
The draught stop behind the rear-seat headr-
ests and the wind deflector in the roof frame
extend simultaneously. The indicator lamp in
switch :lights up.
X To deactivate: press switch:.
The draught stop behind the rear-seat headr-
ests and the wind deflector in the roof frame
retract simultaneously. The indicator lamp in
switch :goes out.
If you park your vehicle with the soft top down
and remove the key, the wind deflector and the
draught stop retract automatically. When you
restart your engine after having been parked,
the wind deflector and the draught stop extend
again automatically.
AIRCAP cannot be extended or retracted if the
vehicle speed exceeds approximately
160 km/h. Folding draught stop
Important safety notes G
WARNING
If you use the draught stop in darkness or in
other conditions offering poor visibility, your
view to the rear is further impaired. There is a
risk of an accident.
Only use the draught stop when visibility con- ditions are good. G
WARNING
If the draught stop is not fitted correctly, it
could come loose during the journey and
endanger other road users. There is a risk of
an accident and injury.
Fit the draught stop as described.
! Fit or remove the draught stop only when
the soft top is open. You could otherwise
damage the draught stop or the vehicle inte-
rior.
! Observe the backrest position of the front
seats if the draught stop is installed, since the
backrest could collide with the draught stop
here.
! Mercedes-Benz recommends that you only
use draught stops which have been tested
and approved for Mercedes-Benz vehicles.
This helps to prevent damage to the vehicle.
The folding draught stop protects against wind
when driving with the soft top open. It is secured
above the rear bench seats. For this reason, only the driver and the front passenger can travel in
the vehicle when the folding draught stop is fit-
ted.
The folding draught stop can be fitted or
removed from the driver's side or passenger
side.
You should preferably perform operations
involving the folding draught stop on the side
facing away from traffic, after you have stopped the vehicle, paying attention to road and traffic
conditions. Convertible top
