252 Operation
Tyres and wheels
The tyre pressure loss warning system is
restricted in its function ordelayed if:
! snow chains are fitted to your vehicle
! road and traffic con ditions are affected
by wintry conditions
! you are driving ove ra loose surface
(e.g. sand or gravel)
! you adopt a sporty driving style (with
high cornering speed or rapid accelera-
tion)
! you are driving with a very heavy or
large trailer
! you are driving with roof loads or very
heavy loads Reactivating the
tyre pressure loss warning feature
You must reactivate the tyre pressure
loss
warning featur ein the following cases, if
you:
! have changed the tyre pressure
! have changed the wheels or tyres
! have fitted new wheels or tyres
6 Before reactivating, make sure that the
tyre pressure of all four tyres is set cor-
rectly for local driving conditions using
the table on the inside of the fuel filler
flap.
6 Make sure that the ignition is switched
on. G
Riskofaccident The tyre pressure loss warning system does
not warn
youof an inco rrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you to decide whether the tyre
pressur eshould be corrected.
The tyre pressure loss warning system isnot
a substitute for check ing the tyre pressures
on a regular basis sin ceequal pre ssureloss
in all fo urtyres cannot be detected by the
tyre pressure loss warning system.
Th etyre pressure loss warning system isnot
able to warn you of a sudden loss of pres-
sure, e.g. following penet ration by aforeign
obje ct. In such cases ,stop th evehicle by
braking carefully. Do notma keany sudden
steering movements. G
Risk of accident Th
ety re pre ssureloss warning system can
only work reliably if you have set the tyre
pressure correctly.
If an incorr ect tyre pressure is set, this in-
correct value will be monitored. 209en_d2.

On vehicles with the same size wheels at
the front and rear, the wheels can be inter-
changed every 5,000 to 10,000 km, de-
pend ing on the degree of tyre wear. The
same direction of rotation must be main-
tained. The front and rear wheels wear differently,
depending on the operating conditions.
Interchange the
wheels before too definite
a wear pattern forms on the tyres. The
front tyres typically wear more on the out-
er shoul der, and the rear tyres in the cen-
tre of the tread.
Each time you interchange the wheels,
you should clean the contact areas on the
wheels and brake discs thoroughly. Check
the tyre pressures. Interchanging wh

Risk of accident Interchange th
efront and rear wheels only if

pag e41). The exterior mirrors or
windscreen wipers cou ldotherwise be damaged.
i Make sure that the mirrors are fully folded
out whe nyou leave the automatic car wash. They
co uld oth erwise vibrate. High-pressure cleaners
!
Do not use high-pressure cleaners with
round-spray jet sfor cleaning the tyres. You could
ot he rwise damage the tyres .Replace damaged
tyres.
6 Direct the high-pressure cleaner nozzle
at the vehicle from a distance of at
least 30 cm.
6 Move the high-pressure cleaner nozzle
around when cleanin gyour vehicle.

Risk of accident If a pressure of 1.8 bar is not obtained with-
in fiv eminutes, the tyre is too badly dam-
aged.

6 If you have obtained a pressure of
1.8 bar, press the switch on the elec-
tric air pum pto 0.
The electric air pump isswitched off.
6 Discon nect the electric air pump.
6 Pull away immediately.
This allows the TIRE FIT sealant to dis-
tribute throughout the tyre.
6 Stop after about ten minutes and
chec kthe tyre pressure with the elec-
tric air pum p.
6If the tyre press ure is at least 1.3 bar,
correct it (see fuel filler flap for values).
To increase the tyre pressure:
6 switch on the electric air pump
To decrease the tyre pressure: 6 open the pr essure release screw on
pressure gauge 9 6
Drive to the nearest workshop and
have the tyre rep lace d.
6 Have the TIREFIT kit replaced as soon
as possible at a qua lified speci alist

6 Have the TIRE FIT kit replaced every
four years at a quali fied specialist
wo rkshop, e.g. a Mercedes-Benz Serv-

Risk of accident If the pressure has fa
llen below1.3 bar, the
tyre is too badly damaged.
