2016 MERCEDES-BENZ GLC COUPE airbag off

Vehicles without the automatic front-
passenger front airbag deactivation
system If the front-passenger seat of your vehicle is not
equipped with the automatic front-passenger
front airbag deactivation system, this is indica-
ted by a special sticker. The sticker is affixed to
the side of the dashboard on the front-
passenger side. The sticker is visible when you
open the front-passenger door.
In this case, never fit a rearward-facing child
restraint system on the front passenger seat
(Y page 61).
Observe the following information under "Rear-
ward-facing child restraint system"
(Y page 61) and "Forward-facing child
restraint system" (Y page 61) as well as infor-
mation on the suitable positioning of the child
restraint system (Y page 61).
Rearward-facing child restraint system If it is absolutely necessary to fit a rearward-
facing child restraint system to the front-
passenger seat, always make sure that the
front-passenger front airbag is disabled. Only if
the PASSENGER AIR BAG OFF indicator lamp is lit continuously (Y page 42) is the front-
passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 61) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions.
Forward-facing child restraint system If it is absolutely necessary to fit a forward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible. Fully retract the seat cushion length. The entire base
of the child restraint system must always rest on the seat cushion of the front-passenger seat.
The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the front-passenger seat. The child restraint sys-tem 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 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 belt sash guide. If neces-
sary, adjust the belt sash guide and the front-
passenger seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 61) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems approved in accord-
ance with ECE standards ECE R44 or ECE R129 (i-Size child restraint systems) are permitted foruse in the vehicle.
"Universal"-category child restraint systems can
be recognised by their orange approval label and the text "Universal" or an "i-Size" label. Children in the vehicle

When you remove the child restraint system, you must replace the head restraints again immedi-
ately (Y page 105). All vehicle occupants must adjust their head restraints correctly before begin-
ning the journey.
Legend for the table:
XS eat that is unsuitable for children in this weight category.
US uitable for child restraint systems in the "Universal" category that are approved for use in this
weight category.
UF Suitable for forward-facing child restraint systems that belong to the "Universal" category and are approved for use in this weight category.
LS uitable for child restraint systems as recommended; see the "Recommended child restraint
systems" table (Y page 65). Suitable for semi-universal child restraint systems if the vehicle

Suitability of the seats for attaching ISOFIX child restraint systems
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.
If you use a category I, forward-facing child restraint system, you should remove the head restraintfrom the respective seat, if possible (Y page 105). The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the seat.
Always observe the notes in the "Child restraint system" section (Y page 57)and the child restraint
system manufacturer's installation instructions.
When you remove the child restraint system, you must replace the head restraints again immedi-
ately (Y page 105). All vehicle occupants must adjust their head restraints correctly before begin-
ning the journey.
Make sure that the child's feet do not touch the front seat. If necessary, move the front seat forward 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.
1 The vehicle is equipped with an automatic front-passenger front airbag deactivation system. The PASSENGER
AIR BAG OFF indicator lamp must be lit.

To switch the hazard warning lamps on or
off: press the :button.
All the indicator lamps will flash when the
hazard warning lamps are switched on. If you
now switch on an indicator lamp using the
combination switch, only the indicator lamp
on the corresponding side of the vehicle will
flash.
The hazard warning lamps switch on automati-
cally if:
R an airbag has been triggered or
R the vehicle decelerates rapidly from a speed
of above 70 km/h and comes to a standstill
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
10 km/h again after a full brake application.
The hazard warning lamps continue to operate
even if the ignition is switched off. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps to suit the prevailing
driving and weather conditions. It offers
advanced functions for improved illumination of the road surface, e.g. depending on the vehicle
speed or weather conditions. The system
includes the active light function, cornering light
function, motorway mode and extended-range
fog lamps. The system is active only when it is
dark.
You can activate/deactivate the Intelligent
Intelligent
Light System Light System function using the on-board
computer (Y page 243).
Active light function The active light function is a system that moves
the headlamps according to the steering move-
ments of the front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals sooner.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane in which you are driving and adjusts the light in
advance. Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can be acti-
vated only when the dipped-beam headlamps
are switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the steer-
ing wheel
R if you are driving at speeds between 40 km/h
and 70 km/h and turn the steering wheel
The cornering light function may remain lit for a short time, but is automatically switched off
after no more than three minutes.
Cornering light function with roundabout
function:
The cornering light function is activated on both
sides before entering a roundabout through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the roundabout. In this way, pedestrians crossing the road, for example, are illuminated
by your vehicle in good time.
Only vehicles with the COMAND multimedia sys-
tem have this function.
Motorway mode Motorway mode increases the range of the
beam.
Active:if you are driving at a speed above
110 km/h and do not make any large steering
movements for at least 1000 m or if you are
driving at a speed above 130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation.
Extended range fog lamps The extended-range fog lamps reduce the glare
experienced by the driver and improve the illu-
mination of the edge of the carriageway.
Active: if you are driving at speeds below
70 km/h and you switch on the rear fog lamp.
Not active: if, following activation, you are driv-
ing at speeds above 100 km/h or if you switch
off the rear fog lamp. 118
