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 proper ly:
R There are cuts or punctures in the tire
lar gerth an those pr eviously mentioned.
R The wheel rim is dama ged.
R You 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 inju ryand poisoning
from tire sealant
The tire sealant is harmful and causes ir rita‐

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 lea ksout, make sure you clean the
af fected area as quickly as possible. It is prefera‐
ble touse clear water.
If yo uge t tire sealant on your clo thing, ha veit
cleaned as soon as possible with per chloroe thy‐
lene.
If a ti repressure of 180 kPa (1.8 bar/26 psi)
has not been attained af ter eight minutes: #
Switch off the tire inflation compressor. #
Unscr ew thefilling hose from theva lve of the
fa ulty tire.
Please no tethat tire sealant may leak out when
unscr ewing thefilling hose. #
Drive forw ards or reve rseve ry slowly for
appr oximately 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. 360

WARNING Risk of accident from driving
wi th sealed tires
A tire temp orarily sealed with tire sealant
impairs driving characteristics and is not
suitable for higher speeds. #
Adapt your driving style according lyand

Do not exceed the maximum speed
limit with a tire that has been repaired
using tire sealant. Obser
vethe maximum permissible speed for a
tire sealed with tire sealant 50 mph (8 0 km/h). #

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
call 1-800-FOR-MERC edes (inthe USA) or
1-800-387-0 100(in Canada). #
Cor rect the tire pressure if it is still at least
13 0 kPa (1.3 bar/19 psi). You will find the
va lues in theTire and Loading In form ation
placard on the B-pillar on the driver's side or
in the tire pressure table in the fuel filler flap. #

DANG ER Risk of accident due toincor‐
re ct tire pressure
Every tire, including the spare (if pr ovided),
should be checked when cold at least once a
month and inflated tothe pressure recom‐
mended bytheve hicle manufacturer (see
Ti re and Loading In form ation placard on the
B-pillar on the driver ’sside or the tire pres‐
sure label on the inside of the fuel filler flap
of your vehicle). If your vehicle has tires of a
dif fere nt size than the size indicated on the
Ti re and Loading In form ation placard or the tire pressu
retable, you need todeterm ine
th e proper tire pressure forth ose tires.
As an added saf etyfe ature, your vehicle has
been equipped with a tire pressure monitor‐
ing sy stem (TPMS) that illuminates a low tire
pressure indicator lamp when one or more of
yo ur tires are significantly underinflated.
Ac cording ly, if the low tire pressure indicator
lamp lights up, you should stop and check
yo ur tires as soon as possible, and inflate
th em tothe proper pressure. Driving on a
significant lyunderinflated tire causes the tire
to ov erheat and can lead totire failure.
Un derinflation also increases fuel consump‐
tion and reduces tire tread life, and may
af fect theve hicle's handling and braking abil‐
ity. Please no tethat the TPMS is not a substi‐
tute for proper tire maintenance, and it is the
driver's responsibility tomaintain cor rect tire
pressure, even if underinflation has not
re ached the le velto trig ger illumination of
th e TPMS low tire pressure indicator lamp.
Yo ur vehicle has also been equipped with a
TPMS malfunction indicator toindicate when th
e sy stem is not operating proper ly. The
TPMS malfunction indica tor is combined with
th e low tire pressure indicator lamp. When
th e sy stem de tects a malfunction, the indica‐
to r lamp will flash for appro ximately a minute
and then remain continuously illumina ted.
This sequence will continue upon subsequent
ve hicle start-ups as long as the malfunction
ex ists.
When the malfunction indicator is illumina‐
te d, the sy stem may not be able todetect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variet y of rea‐
sons, including the ins tallation of incompati‐
ble replacement or alternate tires or wheels
on theve hicle that pr eventthe TPMS from
functioning properly.
Alw aysch eck the TPMS malfunction warning
lamp af terre placing one or more tires or
wheels on your vehicle toensure that the
re placement or alternate tires and wheels
allow the TPMS tocontinue tofunction prop‐
erly. Wheels and tires
