The seat belt may be used to secure univer-
sal type child seats to the vehicle seats
marked with a U in the table below.
If the front passenger seat lacks a height ad-
justment, child seats cannot be mounted is
this location 1)
.
To correctly use a child seat in the back, the
front backrest must be adjusted so that there is no contact with the child seat in the back
in the case th

at it goes opposite to the direc-
tion of the car. In the case of front facing re-
straint systems, the front backrest must be
adjusted so that there is no contact with the
child's feet.
To adjust the passenger seat to accommo-
date a child's seat and get the seat belt in a
perfect position, adjust the passenger back-
rest as far forward as possible. 1)
.
Starting with Group 0+ child seats should not
be mounted facing backwards in the passen-
ger seat given that due to the size of some of
them, they can be difficult to install. 1)

Compliance with current national legislation and
the manuf act

urer's instructions is required when us-
ing or installing child seats. 20

*:
“ISOFIX” and Top Tether child seat mounting system* Child seats can be secured quickly, easily
and s
af
ely

on the rear outer seats with the
“ISOFIX” and Top Tether* system.
Two “ISOFIX” retaining rings are fitted on
each rear seat. In some vehicles, the rings
are secured to the seat frame and, in others,
they are secured to the rear floor. The “ISO- FIX” rings are located between the rear seat
back
rest and the seat cushioning. The Top
Tether* rings are located at the rear of the
backrests of the rear seats (behind the seat
backrest or in the boot). To understand the compatibility of the "ISO-
FIX" syst
ems in the vehicle, consult the table
below.
The body weight permitted and information
regarding sizes A to F is indicated on the la-
bel on child seats with “ universal” or “semi-
universal” certification. » 21

t
ur
er's

instructions.
● Remove the protective caps of the “ISOFIX”
rings
by placing a finger in the hole and pull-
ing up ››› Fig. 31.
● Press the child seat onto the “ISOFIX” re-
taining rin
gs until the child seat can be heard
to engage securely. If the child seat is equip-
ped with Top Tether* anchor points, secure it
to the correspondent ring ››› Fig. 32. Observe
the manufacturer's instructions.
● Pull on both sides of the child seat to en-
sure th
at it is properly anchored.
Child seats with the “ISOFIX” and Top Tether*
attachment system are available from Techni-
cal Services. Attachment of the child seat with the
Top T

ether* retainer straps Fig. 32
Position of the Top Tether rings on the

of the rear seat. Child seats with the Top Tether system come
w
ith a s
tr

ap for securing the seat to the vehi-
cle anchor point, located at the back of the
rear seat backrest and provide greater re-
straint.
The objective of this strap is to reduce for-
ward movements of the child seat in a crash,
to reduce the risk of injuries to the head from
hitting the inside of the vehicle.
Using the Top Tether in rear-facing mounted
seats
Currently, there are very few rear-facing child
safety seats that have Top Tether. Please
carefully read and follow the seat manufac-
turer instructions to learn the proper way to
install the Top Tether strap. Securing the Top Tether* to the an-
chorag

Adjus t
the driver's seat so that there is at
least 25 cm distance between the centre of
the chest and the centre of the steering
wheel ››› Fig. 82. If you are sitting closer than
25 cm, the airbag system cannot protect you
properly.
● If your physical constitution prevents you
from maint
aining the minimum distance of 25
cm, contact a specialised workshop. The
workshop will help you decide if special spe-
cific modifications are necessary.
● When driving, always hold the steering
wheel with both h
ands on the outside of the
ring at the 9 o'clock and 3 o'clock positions.
This reduces the risk of injury when the driver
airbag is triggered.
● Never hold the steering wheel at the 12
o'clock
position, or in any other manner (e.g.
in the centre of the steering wheel). In such
cases, if the airbag is triggered, you may sus-
tain injuries to the arms, hands and head.
● To reduce the risk of injury to the driver
during sud
den braking manoeuvres or an ac-
cident, never drive with the backrest tilted far
back! The airbag system and seat belts can
only provide optimal protection when the
backrest is in an upright position and the
driver is wearing his or her seat belt correct-
ly.
