\3 Fuel systemOn vehicles with a diesel engine, it is nec-
essary to drain the fuel filter if the/ in-
dicator lamp lights up.
To this end, have the fuel filter with water
separator drained at an authorized Sprint-
er Dealer which has the necessary special-
ist knowledge and tools to carry out the
work required.The fuel filter with water separator is in the
engine compartment.
1Drain hose
2Drain plug
\1Apply the handbrake and move the se-
lector lever to positionP.
\1Switch off the engine and open the
hood (\2page 185).
\1Place a suitable container under drain
hose1.
\1Switch on the ignition (\2page 67).\1Unscrew drain plug2 immediately
one turn or until liquid flows out of
drain hose1.
\1Make sure that the liquid flows into the
container under drain hose 1.
\1Close drain plug 2 as soon as approx-
imately 0.2 US qt (0.2 l) of liquid has
been collected.
\1When you have drained the fuel filter
with water separator, turn the key back
to position0 in the ignition lock
(\2page 67).
\1Dispose of the collected liquid in an en-
vironmentally responsible manner.Draining the fuel filter!
CAUTION
Drain the fuel filter with water separa-
tor immediately if the/ indicator
lamp lights up. The engine could be
damaged.
Environmental note
H
When handling, storing and disposing of die-
sel and diesel mixtures, please observe the
relevant regulations.
iThe electric fuel delivery pump stops
the flow of liquid automatically after
30 seconds.

Tire sealant must not come into contact with
your skin, eyes or clothing.
\4If tire sealant comes into contact with
your eyes or skin, immediately rinse
thoroughly with clean water.
\4Immediately change out of clothing that
has been in contact with tire sealant.
\4If an allergic reaction occurs, consult a
doctor immediately.
Keep tire sealant away from children.
\4If tire sealant is swallowed, immediately
rinse your mouth out thoroughly and
drink plenty of water.
\4Do not induce vomiting. Consult a doc-
tor immediately.
Do not inhale tire sealant fumes.
iThe tire sealant is water soluble. If tire
sealant escapes, you can wash it away
with water.

\1Start the engine (\2page 111).
\1Press I on electric air pump switch1.
The electric air pump is switched on.
The tire sealant is then pumped into
the tire and the tire pressure is in-
creased. Allow the electric air pump to
run for at least 10 minutes until tire
sealant bottle 8 is completely empty
and a minimum tire pressure of
43.5 psi (3.0 bar) is achieved.
\1Inflate the tire using the electric air
pump until the recommended tire pres-
sure (\2page 210) is achieved.
\1Then press0 on electric air pump
switch1.
The electric air pump is switched off.
\1Slide knoba quickly to the stop in
valve core extractorc.
\1Turn knob a clockwise until the valve
core is firmly screwed into tire
valved.
\1Press leverb and remove valve core
extractorc from tire valved.
\1Screw the valve cap onto tire valved.

aValve core extractor
\1Unscrew and remove the valve cap
from valve extension9 on the flat tire.
\1Screw valve core extractora clock-
wise all the way onto valve
extension9.
\1Continue to screw valve core
extractora about half a rotation to
loosen the valve extension.
\1Unscrew and remove the valve exten-
sion and valve core extractor counter-
clockwise from tire valve.
\1Unscrew and remove the valve exten-
sion from the valve core extractor.
!
CAUTION
Do not connect the electric air pump
connector to the cigarette lighter sock-
et or another 12 V socket. These are
not designed for operating the electric
air pump.
!
CAUTION
Do not run the electric air pump for
more than 20 minutes without a break,
otherwise it may overheat.
The air pump can be used again once it
has cooled down.
iDo not pull the valve core extractor
from the tire valve while the valve core
is unscrewed from the tire valve. Tire
sealant could otherwise escape onto
your hands.
The tire sealant is water soluble. If tire
sealant escapes, you can wash it away
with water.

After filling with tire sealant
\1Turn the pressure release screw on
pressure gauge5 counterclockwise
and bleed the system.
\1Turn the key to position0 in the igni-
tion lock (\2page 67).
\1Pull the electric air pump connector out
of the 12 V socket.
\1Store the electric air pump, tire sealant
bottle 8 with valve core extractorc
and, if used, the warning triangle and
hazard warning lamps inside the vehi-
cle.\1Unscrew and remove angle bracket 2
from valve7 on tire sealant bottle 8
and screw the valve cap onto the valve.
\1Pull away immediately.
This enables the tire sealant to distrib-
ute inside the tire and create a more ef-
fective seal.
\1Stop after about 3 minutes and check
the tire pressure using the electric air
pump, for example.\1Correct the tire pressure accordingly if
it does not correspond to the recom-
mended tire pressure (\2page 210).
Increasing the tire pressure
\1Switch on the electric air pump.
Reducing the tire pressure
\1Open the pressure release screw
on pressure gauge 5.
\1Drive to the nearest workshop and
have the tire repaired or replaced.
\1Clean the valve core extractor using
clean water.
\1Have tire sealant bottle8 replaced as
soon as possible at an authorized
Sprinter Dealer.

Do not exceed the maximum speed of
50 mph (80 km/h).
The "max. 50 mph (80 km/h)" sticker must
be affixed within the driver's field of vision.
The vehicle’s handling characteristics may
be affected.iYou must connect the angle bracket on
hose 3 of the electric air pump direct-
ly to the tire valve on the tire.
