RTIREFIT sticke r pr ovided
RTire inflation compressor
RDisposable glove s
Yo u can use TIREFIT tire sealant toseal per fora ‐
tion damage of upto0.16 in (4 mm), particular lyth
ose in the tire conta ct surface.You can use
TIREFIT inoutside temp eratures down to-4 °F
(-20 °C).
& WARNING Risk of accident when using
tire sealant.
In thefo llowing situations, the tire sealant is
unable toprov ide suf ficient breakdown assis‐
ta nce, as it is unable toseal the tire properly:
RThere are cuts or punctures in the tire
larger than those pr eviously mentioned.
RThe wheel rim is dama ged.
RYo u ha vedriven at a very low tire pres‐
sure or on a flat tire.
#Do not continue driving.
#Consult a qualified specialist workshop.

WARNING Risk of injury and poisoning
from tire sealant
The tire sealant is harmful and causes ir rita ‐
tion. Do not allow it tocome into contact
wi th th e skin, eyes or clo thing, and do not

swallow it. Do not inhale tire sealant fumes.
Keep the tire sealant away from children.
If yo u come into contact withth e tire sealant,
obser vethefo llowing:
#Rinse off the tire sealant from your skin
immediately using water.
#If tire sealant gets into your eyes, thor‐
oughly rinse out theey es using clean
wate r.
#If tire sealant has been swallowe d,
immediately rinse out the mouth thor‐
oughly and drink plenty of water.Do not
induce vomiting and seek medical
attention immediately.
#Change out of any clo thes conta mina‐

#Switch on the ignition.
#Press on and off switch 3onthe tire infla‐

The tire inflation compressor is switched on.
The tire is inflated. Fir st, tire sealant is pum‐
ped into the tire. The pressure may brief ly
ri se toappr oximately 500 kPa (5 bar/73 psi).
Do not switch off the tire inflation compres‐
sor du ring this phase.
#Let the tire inflation compressor runfo r a
maximum of eight minutes.
The tire should then ha veattained a tire
pressure of at least 180 kPa (1.8 bar/26 psi).
If tire sealant leaks out, make sureyou clean the
af fected areas as quickly as possible. It is pref‐
erable touse clean water.
If yo uge t tire sealant on your clo thing, ha veit
cleaned as soon as possible with per chloroe thy‐
lene.
If atire pressure of 180 kPa (1.8 bar/26 psi)
has not been attained af ter eight minutes:
#Switch off the tire inflation compressor.
#Un scr ew thefilling hose from theva lve of the
defective tire.
Please no tethat tire sealant may leak out when
unscr ewing thefilling hose.
#Ve ry slowly drive forw ards or reve rse appr ox‐
imately 33 ft(10 m).
#Pump up the tire again.
Af ter a maximum of eight minutes the tire
pressure must be at least 180 kPa (1.8 bar/
26 psi).
& WARNING Risk of accident due tothe
specified tire pressure not being reached
If th e specified tire pressure is not reached
af te rth e specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this ins tance.
Dama ged tires and a tire pressure that is too
low can significantly impair braking and han‐
dling characteristics.
#Do not continue driving.
#Consult a qualified specialist workshop.

WARNING Risk of accident due tothe
specified tire pressure not being reached
If th e specified tire pressure is not reached
af te r a brief drive, the tire is too badly dam‐
aged. The tire sealant cannot repair the tire
in this ins tance.
Dama ged tires and tire pressure that is too
low can significantly impair the braking prop‐
erties and the handling characteristics.
#Do not continue driving.
#Consult a qualified specialist workshop.
In cases such as the one mentioned abo ve, con‐
ta ct an au thorized Mercedes-Benz Center. Or
