secure achild in achild restraint system on the
front-passenger seat:
X Always pay attentio ntotheinstruction sunder

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.

47Safety Z
Pay particular attention to damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on the tyres
R deformation or severe corrosion on the
wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width of
the tyre (Y page 236). In order to inspect the
inner side of the tyre surface, turn the steering
wheel to full lock.
All wheels must have avalve cap to protec tthe
valve against dirt and moisture. Do not fit any-
thing ontot he valve other than the standard
valve cap or avalve cap approved by Mercedes-
Benz for your vehicle. Do not fit any other valve caps or systems, e.g. tyre pressure monitors.
You should regularly check the pressure of all
your tyres including the spare wheel, particu-
larly prior to long trips. Adjust the tyre pressure as necessary (Y page 238).
The service life of atyre depends on various fac-
tors, including the following:
R driving style
R tyre pressure
R mileage Notes on th
etyre tread G
WARNING
Insuffic ient tyre tread willr educe tyre trac-
tion. The tyre is no longer abletod issipate
water .This means that on wet road surfaces,
the risk of aquaplaning increases, in particular where spee disnot adapted to suitt he driving
conditions. There is arisk of accident.
If the tyre pressure is too high or too low,t yres
may exhibi tdifferent levels of wearatd iffer-
ent locations on the tyre tread. Thus ,you
should regularl ycheck the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimu mtyre tread depth for:
R summe rtyres: 3mm
R M+S tyres: 4mm For safety reasons, replace the tyre
sbefore
the legally prescribed limit for the minimum
tyre trea ddepth is reached. Select
ing, fitting and replacing tyres G
WARNING
Exceeding the state dtyre load-bearing capa-
city and the approved maximu mspee dcould
leadtot yre damage or the tyre bursting. There
is ar isk of accident.
Therefore, only use tyre types and sizes
approved for yourv ehiclemodel .Observe the
tyre loadr ating and spee drating required for
yourv ehicle.
Pay special attention to country-specific
requirements for tyre approval .These require-
ments may stipulate aspecific tyre type for your
vehicle. Furthermore ,the use of aspecific tyre
type in certain regions and area sofoperation
can be highly beneficial .You can find further
information regarding tyres at specialist tyre
retailers, at qualified specialist workshops or at
any Mercedes-Benz Service Centre.
R Use only tyres and wheels of the same type
and make.
R Fit only tyres of the correct size onto the
wheels.
R Runinn ew tyres at moderate speeds for the
first 100 km. They reach their full perform-
ance only after this distance.
R Do not drive with tyres that have too little
tread depth. This significantly reduces trac-
tion on wet road s(aquaplaning).
R Replace the tyres after six years at the latest,
regardless of wear. This alsoa ppliestothe
spar ewheel. Winter operation
