2013 MERCEDES-BENZ GLA SUV belt

Top Tether
Introduction Top Tether provides an additional connection
between the child restraint system secured
with ISOFIX and the rear seat. It helps reduce
the risk of injury even further. If the child
restraint system is fitted with a Top Tether
belt, this should always be used.
Important safety notes G
WARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an acci-
dent, heavy braking or sudden changes of
direction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g. in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after fitting a Top Tether belt. Observe the lock verificationindicator. Adjust the rear seat backrests so
that they are in an upright position.
Top Tether anchorages The Top Tether anchorages are located on the
rear side of both outer rear seat backrests. Vehicles with adjustable head restraints:

head restraint :upwards.
X Route Top Tether belt ?under head
restraint :between the two head restraint
bars.
or

rect routing of Top Tether belt ?.Child restraint system on the front-
passenger seat
General notes Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat.
Vehicles with the automatic front-passenger
front airbag deactivation system: if it is abso- lutely necessary to fit a child restraint system
to the front-passenger seat, always observe
the information on "Automatic front-
passenger front airbag deactivation system"
(Y page 51).
You can thus avoid the risks that could arise
as a result of:
R a child restraint system that is not detected
by the automatic front-passenger front air- bag deactivation system
R the unintentional disabling of the front-
passenger front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board Please observe the warning notice on the
front-passenger sun visor, see the illustra-
tion.
G
WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The childcould be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
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.
If the PASSENGER AIR BAG ON indicator lamp
is lit, the front-passenger front airbag is ena-
bled (Y page 43). Children in the vehicle

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 indicated 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, always fit the rearward-facing
child restraint system to a suitable rear seat
(Y page 64).
Observe the following information under
"Rearward-facing child restraint system" and
"Forward-facing child restraint system" as
well as information on the suitable position-
ing of the child restraint system
(Y page 64).
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 permanently lit (Y page 43) is the
front-passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 64) in addition to the child restraint
system manufacturer's installation and oper-
ating 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.
Always make sure that the shoulder belt strap
is correctly routed from the vehicle belt outlet to the shoulder belt guide on the child
restraint system. The shoulder belt strap
must be routed forwards and downwards
from the vehicle belt outlet. If necessary,
adjust the vehicle belt outlet and the front-
passenger seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 64) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems which are
approved in accordance with the ECE stand-
ard ECE R44 are permitted for use in the vehi- cle.
Child restraint system on the front-
passenger seat – if it is absolutely necessary
to fit a child restraint system to the front-
passenger seat:
X Always pay attention to the instructions
under "Child restraint system on the front-
passenger seat" (Y page 63).
There you will find instructions on how to
correctly route the shoulder belt strap from the vehicle belt outlet to the shoulder belt
guide on the child restraint system
(Y page 64).
X 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, you must also move the 64
Children in the vehicleSafety

front-passenger seat to the highest posi-
tion.
X Move the backrest to an almost vertical
position.
The bottom and back of a forward-facing
child restraint system must make full con-
tact with the front-passenger seat cushion
and backrest. The child restraint system
must not touch the roof. Adjust the back-
rest angle accordingly. Also observe the
child restraint system manufacturer's
installation instructions.
X For seats with electrical adjustment, the
seat cushion angle must be set to the high-
est and most upright position.
For certain child restraint systems in
weight category III, this can mean that the
area of use is restricted. The maximum size setting of the child restraint system is not
possible due to possible contact with the
roof.
"Universal" category child restraint systems
can be recognised by their orange approval
label and the text "Universal". Example: approval label on the child restraint sys-
tem
"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 vehi- cle 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. Children in the vehicle

COLLISION PREVENTION ASSIST PLUS
General notes
COLLISION PREVENTION ASSIST PLUS is
only available on vehicles with DISTRONIC.
COLLISION PREVENTION ASSIST PLUS
extends the functionality of COLLISION PRE-
VENTION ASSIST with an automatic braking
function. COLLISION PREVENTION ASSIST
PLUS can help you to minimise the risk of a
front-end collision with a vehicle ahead or
reduce the effects of such a collision. If COL-
LISION PREVENTION ASSIST PLUS detects
that there is a risk of a collision, you will be
warned visually and acoustically. In critical
situations COLLISION PREVENTION ASSIST
PLUS also initiates automatic braking.
Function X To activate/deactivate: activate or deac-
tivate COLLISION PREVENTION ASSIST
PLUS in the on-board computer
(Y page 244).
If COLLISION PREVENTION ASSIST PLUS is
deactivated, the æsymbol appears in the
assistance graphics display.
If the driver's seat belt is fastened, COLLI-
SION PREVENTION ASSIST PLUS can brake
automatically within a speed range of
between 7 km/h and 200 km/h.
COLLISION PREVENTION ASSIST PLUS can
also react to stationary obstacles with auto-
matic braking within a speed range of
between 7 km/h and 30 km/h.
Vehicles with PRE-SAFE ®
:if the automatic
braking function of COLLISION PREVENTION
ASSIST PLUS intervenes powerfully, preven-
tive passenger protection measures (PRE-
SAFE ®
) are deployed simultaneously.
In particular, the detection of obstacles can
be impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources R
strong radar reflections, for example, in
multi-storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different
line
R new vehicles or after a service on the COL-
LISION PREVENTION ASSIST PLUS system
Please observe the information in the sec-
tion on running-in the vehicle
(Y page 158).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle. Adaptive brake lamps
The adaptive brake lights warn following traf- fic in an emergency braking situation:
R by means of flashing brake lamps
R the hazard warning lamps are activated
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS, the brake lamps flash rapidly. In
this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn- ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard
warning button (Y page 123). ESP

WARNING
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
You could lose control of the vehicle while
driving if you:
R adjust the driver's seat, steering wheel or
mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirrors and fasten your seat
belt 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 seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder. 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. Seats
