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
"Universal "category child restraint system scan
be used on the seats indicated with UorL
according to the table s"Suitability of the seats
for attaching belte dchild restraint systems" or 46

"Suitabilit
yoftheseat sfor attaching an ISOFIX
child restraint system".
Semi-universal child restraint systems are indi-
cated by th etext"semi-universal" on the
approval label. Thes ecan be used if th evehicle
and th eseat are listed in th echild restraint sys-
te mm anufacturer' svehicle model list .For more
information, contact th echild restraint system
manufacturer or visit their website.
Child restrain tsystem on th efront-
passenger seat – if it is absolutely necessary to
secure achild in achild restraint system on the
front-passenger seat:
X Always pay attentio ntotheinstruction sunder
"Child restraint system on th efront-
passenger seat "(Ypage 43).
Ther eyou will fin dinstruction sonhow to cor-
rectly rout ethe shoulder belt strap from the belt sash guide to the shoulder belt guide on
the child restraint syste
m(Ypage 45).
X Move the front-passenger seat as far back as
possible and int othe lowest position.
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 a
forward-facin gchild restraint system must, as
far as possible, rest flat against 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. Also observe
the child restraint system manufacturer's
installation instructions.
Suitability of the seats for attaching belt-secured child restraint systems If you use
ababy car seat of category 0or0+orarearward-facing child restraint system of category
Ionar ear 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 acategory I, forward-facing child restraint system, you shouldr emove the head restraint
from the respective seat, if possible (Y page 70). The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the seat.
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.
Alwayso bserve the notes in the "Child restraint system" section (Y page 40) 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 70). All vehicle occupants must adjust their head restraints correctly before begin-
ning the journey.

merely aids designed to assist driving .You are
responsible for maintainin gthe distanc etothe

goo dtime, and for staying in lane. Always adapt
your driving style to suit th eprevailing road and weather conditions and maintain
asafe distance
fro mt hevehicle in front .Drive carefully.
The driving safet ysystems described work as
effectively as possible only when there is ade-
quate contac tbetween th etyres and th eroad
surface. Pay particular attention to th einforma-
tio nr egarding tyres, recommended minimum
tyr etread depths etc .inthe"Wheels and tyres"

In wintry driving conditions ,always use winter

systems described in this sectio nwork as effec-
tively as possible. ABS (Anti-lock Braking System)
Genera linformation AB
Sregulate sbrake pressure in such awaythat
the wheels do not lock when yo ubrake. This
allows yo utocontinue steering the vehicl ewhen
braking.

ment cluster lights up when the ignition is
switched on. It goe soutwhen the engine is run-
ning.
ABS works from aspeed of abou t8km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces ,evenw heny ou

WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired.A ddition-
ally, further driving safety systems are deac-
tivated. There is an increased dange rofskid-
ding and accidents.
Drive on carefully.H ave ABS checked imme-
diately at aqualified specialist workshop.

If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is arisk of accident.
In an emergency braking situation, depress
