horizontally on the left side of the wheel for
the repair process.
X Remove the cap from valve 001Con the
defective tire.
X Guide the valve tool through the hole in the
wheel and push it onto tir evalve 001C.
X Hold handle 001Aof the valve tool with one
hand and unscrew the valv ecore with the
other hand using rotating collar 001Bof the
valve tool.
X Remove the valve tool through the gap
carefully, so that the valve core remains
engaged in the valve tool. X
Hang tire sealant bottle 0019in the upper
ventilation hole in the wheel using hook
001E.
X Push angled valve adapter 001Dlocated on
the hose of tire sealant filler bottle 0019as
far as it will go onto valve 001Cand fix it in
place.
X Make sure that the pressure release screw
on pressure gauge 0023is closed.
X Connect connector 0024to the 12 V socket
(12 V, 25 A, 300 W) on the center console
(Y page 228).
X Start the engine.
X Press switch 0005on the tire inflation
compressor to position I.
The tire inflation compressor is activated.
The tire sealant is then pumped into the tire
and the tire pressure is increased. Let the
tire inflation compressor run until tire
sealant bottle 0019is completely empty.
X After approximately 15 seconds, press 0on
tire inflation compressor switch 0005.300

X Screw in the valve core again using the
valve tool and remove the valve tool
through the opening.
i If the valve insert is damaged or lost when
it is unscrewed, you can use the valve insert
from tire sealant bottle 0019after you have
used the tire sealant.
X Unscrew the valve insert from the valve of
tire sealant bottle 0019using the valve
extractor.
X Push angled valve adapter 0006located on
hose 0026of the tire inflatio ncompressor as
far as it will go ontot ire valve001Cand clamp
it in place.
X Press tire inflation compressor switch 0005
to Iand inflate the tire.
If possible, inflate the tire to the
recommended tire pressure. You will find a
table of recommended tir epressure on the
Tire and Loading Information placard 10
or
the tire pressure plate on the B-pillar on the
driver's side of the vehicle (Y page 278).
X Then press 0on tire inflation compressor
switch 0005.
The tire inflation compresso ris
deactivated.
X Screw the valve cap onto tire valve 001C.
X Observe the following notes and
instructions:
R
Tire pressure of 300 kPa (3.0 bar/
43.5 psi) not reached (Y page 301).
R Tire pressure of 300 kPa (3.0 bar/
43. 5psi) reached (Y page 301).
Tire pressure of 300 kPa (3.0 bar/
43.5 psi) not reached G
WARNING
If the specified tire pressure is not reached,
the tire is too severely damaged.T he tire
sealant cannot offer assistance with a flat tire in this case. Damaged tires as well as tire
pressure that is too low can impair the braking
and driving characteristics. There is a risk of
an accident.
Do not drive any further. Notify a qualified
specialist workshop.

telephone numbers can be found on a
sticker in the driver's door entrance area
and in the vehicle Maintenance Booklet.
Tire pressure of 300 kPa (3.0 bar/
43.5 psi) reached G
WARNING
At ire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed
the specified maximum speed with a tire that
has been repaired using tire sealant.
The maximum speed for a tire sealed with tire
sealant is 50 mph (80 km/h).
The "max. 50 mph" (80 km/h) sticker must
be affixed within the driver's field of vision.
X Turn the pressure release screw on
pressure gauge 0023counter-clockwise and
bleed the system.
X Turn the key in the ignition lock to
position 0.
X Pull connector 0024on the tire inflation
compressor out of the 12 V socket.
X Clean the valve core extractor with clean
water.
X Remove angled valve adapter 0006from valve
0018 of tire sealant filler bottle 0019and screw
the valve cap onto valve 0018.
X Stow the tire inflation compressor, tire

and/or valve tool, warning triangle and
warning lamps in the vehicle.
X Pull away immediately.
This enables the tire sealan tto distribute
inside the tire and create a more effective
seal.
X After driving for approximately 3 minutes,
stop the vehicle at a suitable location, e.g.
at a car park or gas station.
X Check the tire pressure again.
The tire pressure must be at least
300 kPa (3.0 bar/43.5 psi). G
WARNING
If the required tire pressure is not reached
after driving for a short period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving
characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
i The Mercedes-Benz Service24h
telephone numbers can be found on a
sticker in the driver's door entrance area
and in the vehicle Maintenance Booklet.
i If you check the tire pressure with the tire
inflation compressor, connect angled valve
adapter 0006on tire inflation compressor
hose 0026directly to the tire valve. The tire
pressure will increase when you switch the
tire inflation compressor on. You can
reduce the tire pressure by opening the
pressure release screw on pressure gauge
0023.
If the tire pressure is still at least 300 kPa
(3.0 bar/43.5 psi):
X If possible, inflate the tire to the
recommended tire pressure (Y page 278).
X Drive to the nearest qualified specialist
workshop as soon as possible and have the
tire and tire sealant 0019replaced. Changing wheels

WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions.
The wheel brakes or suspension components
may also be damaged. There is a risk of
accident.
Rotate front and rear wheels only if the wheels
and tires are of the same dimensions.
! On vehicles equipped with a tire pressure
monitor, electronic components are
located in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the
electronic components.
Only have tires changed at a qualified
specialist workshop.
Always observe the instructions and safety
notes in the "Mounting awheel" section
(Y page 303).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the
intervals in the tire manufacturer's warranty
book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,000 km), or earlier if tire wear requires. Do
not change the direction of rotation.
Clean the contac tsurface softhe wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressure and
reactivate the tire pressure monitor if
necessary. 302
