child restraint systems are approved in accord-
ance with ECE R-44. i-Size child restraint sys-
tems are approved in accordance with ECE
R-129.
Only child restraint systems that have been
approved in accordance with ECE R-44 may be
attached to ISOFIX securing rings. i-Size child
restraint systems that have been approved in
accordance with ECE R-44 and ECE R-129 may

Introduction Top Tether provide
sanadditional connection
between the child restraint system secured with
ISOFIX and the vehicle .Ithelps reduce the risk
of injury even further. If the child restraint sys-
tem is fitted with aTop Tether belt, this should
always be used.
Important safety notes G
WARNING
If the rear seat backrests are not locked, they
could fold forward sinthe event of an acci-
dent, heavy braking or sudden changes of
direction. As aresult, child restraint systems
cannot perform their intended protective
function. Rears eat 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.
Alwaysl ock rear seat backrests after fitting a
Top Tether belt. Observe the lock verification indicator.
If the rear seat backrest is not engaged and
locked, this willbes hown in the multifunction
display in the instrument cluster. Awarning tone
also sounds.

General notes Accident statisticss
how that children secured
in the rear seats are safer than children secured
in the front seats. For this reason, Mercedes-
Benz strongly advises that you fit achild
restraint system on arear seat.
Vehicles with the automatic co-driver's front air-
bag deactivation system: if it is absolutely nec-
essary to fit achild restraint system to the co-
driver's seat, always observe the notes on the
"Automatic co-driver's front airbag deactivation system" (Y page 47). You can thus avoid the risks that could arise as
ar esult of:
R ac hild restraint system that is not detected
by the automatic co-driver's front airbag
deactivation system
R the unintentional disabling of the co-driver's
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 co-
driver's sun visor, see the illustration. G
WARNING
If you secure achild on the co-driver's seat in
ar earward-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 child could 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.
NEVERu searearward-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 AIRBAG ON indicator lamp is
lit, the co-driver's front airbag is enabled

WARNING
If you leave animals unsupervised or unse-
cured in the vehicle, they may push abutton
or as witch, for example.
They could:
R activate vehicle equipment and become
trapped, for example
R switch vehicle systems on or off, thus
endangering other road users
In the event of an accident, sudden braking or
abrupt changes of direction, unsecured ani-
mals could be flung around the vehicle, injur-
ing the vehicle occupants. There is arisk of an
accident and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals correctly during a
journey, e.g. in an animal transport box. Driving safety systems
Driving safety systems overview
In this section,y ou will find information about
the following driving safety systems:

Brake (Y page 75)
R STEERC ONTROL (Y page 77) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther 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 maintaining the distance to the
vehicle in front,f or vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather condition sand maintain asafe distance
from the vehicle in front.D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tyres and the road
surface. Pay particular attention to the informa- tion regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and tyres" section (Y page 353).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-loc
kBraking System)
General notes ABS regulates brake pressure in such
away that
the wheels do not lock when you brake. This
allowsy ou to continue steering the vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from aspeed of about 8km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristic smay be severely impaired. Addition-
ally,f urther driving safety systems are deac- 66
