WARNING Risk of accident from driving
wi th sealed tyres
A tyre temp orarily sealed with tyre sealant
impairs the handling characteristics and is
not suitable for higher speeds. #
Adapt your driving style according lyand
drive carefull y. #
Do not exceed the maximum speed
limit with a tyre that has been repaired
using tyre sealant. #
Obser vethe maximum permissible speed for
a tyre sealed with tyre sealant 80 km/h. #
Affix th e upper section of the TIREFIT sticker
to the instrument clus ter in a location where
it will be easi lyseen bythe driver.
* NO
TEStaining from leaking tyre sealant Af
ter use, excess tyre sealant may leak out
from thefilling hose. #
Therefore, place thefilling hose in the
plastic bag that con tained the TIREFIT
kit. +

sponsible disposal Ty
re sealant contains polluta nts. #
Have the tyre sealant bottle disposed of
professionall y,e.g. at a Mercedes-Benz
Service Centre. #
Stow th e tyre sealant bottle, the tyre inflation
compressor and thewa rning triangle. #
Pull away immediatel y. #
Stop driving af ter appro ximately ten minu tes
and check the tyre pressure using the tyre
inflation compressor.
The tyre pressure must now be at least
13 0 kPa (1.3 bar). &
WARNING Risk of accident due tothe
specified tyre pressure not being
attained
If th e specified tyre pressure is not reached,
th e tyre is too badly damaged. The tyre seal‐
ant cannot repair the tyre in this ins tance.
The braking and driving characteristics may
be great lyimpaired. #
Do not continue driving. #
Consult a qualified specialist workshop. Countries

side. #
Cor rect the tyre pressure if it is still at least
13 0 kPa (1.3 bar). See the tyre pressure
ta ble on the fuel filler flap forva lues. #
Toincrease the ty repressure: switch on
th e tyre inflation compressor. Breakdown assis

&
WARNING Risk of accident from repea‐
te d tyre pressure drop
If th e tyre pressure drops repeatedl y,the
wheel, valve or tyre may be damaged.
Insuf ficient tyre pressure can cause the tyres
to bur st. #
Inspect the tyre for signs of fore ign
objects. #
Check whe ther the wheel or valve has a
leak. #
Ifyo u are unable torectify the damage,
conta ct aqualified specialist workshop. Information on
there commended tyre pressure
fo rth eve hicle's factor y-fitted tyres can be found
on the tyre pressure table on the inside of the
fuel filler flap (/ page 323).
Use a suitable pressure gauge tocheck the tyre
pressure. The outer appearance of a tyre does
not permit any reliable conclusion about the tyre
pressure. Only cor
rect tyre pressures when the tyres are
cold. Conditions for cold tyres:
R The vehicle has been par ked with the tyres
out of direct sunlight for at least thre e hours.
R The vehicle has tr avelled less than 1.6 km.
The vehicle's tyres heat up when driving. As the
te mp erature of the tyres increases, so too does
th e tyre pressure.
Ve hicles with a tyre pressure monitoring sys‐
te m: you can also check the tyre pressure using
th e on-board computer. Ty
re pressure table The tyre pressure
table is on the inside of the
fuel filler flap. If one or more tyre sizes precede a tyre pres‐
sure,
thefo llowing tyre pressure information is
only valid forth ose tyre sizes and their respec‐
tive load condition.
If th e preceding tyre sizes are complemented by
th e+ symbol, the tyre pressure information
fo llowing sho wsalternative tyre pressures. Fuel
consum ption may then increase slightl y. Wheels and tyres
