254Vehicle care3. Remove the electrical connectioncable and air hose from the
stowage compartments on the
underside of the compressor.
4. Screw the compressor air hose to
the connection on the sealant
bottle.
5. Fit the sealant bottle into the retainer on the compressor.
Set the compressor near the tyre
in such a way that the sealant
bottle is upright.
6. Unscrew valve cap from defective
tyre.
7. Screw the filler hose to the tyre valve.
8. The switch on the compressor must be set to J.
9. Connect the compressor plug to the power outlet or cigarette
lighter socket.
To avoid discharging the battery, we recommend running the
engine.10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to six bar
whilst the sealant bottle is
emptying (approx. 30 seconds).
Then the pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is inflated.
13. The prescribed tyre pressure should be obtained within ten
minutes. Tyre pressure 3 288.
When the correct pressure is
obtained, switch off the
compressor.

262Vehicle careJump startingDo not start with quick charger.
A vehicle with a discharged battery
can be started using jump leads and the battery of another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
● Never expose the battery to naked flames or sparks.
●A discharged battery can already
freeze at a temperature of 0 °C.
Defrost the frozen battery before
connecting jump leads.
● Wear eye protection and protective clothing when
handling a battery.
● Use a booster battery with the same voltage (12 Volts). Its
capacity (Ah) must not be much less than that of the discharged
battery.
● Use jump leads with insulated terminals and a cross section of
at least 16 mm 2
(25 mm 2
for
diesel engines).
● Do not disconnect the discharged
battery from the vehicle.
● Switch off all unnecessary electrical consumers.
● Do not lean over the battery during jump starting.
● Do not allow the terminals of one
lead to touch those of the other
lead.
● The vehicles must not come into contact with each other during
the jump starting process.● Apply the parking brake, transmission in neutral,
automatic transmission in P.
● Open the positive terminal protection caps of both batteries.
Lead connection order:
1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged battery.

Vehicle care2633. Connect the black lead to thenegative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as far away from the discharged
battery as possible, however at
least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After five minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of one
minute.
3. Allow both engines to idle for approx. three minutes with the
leads connected.4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Insert a screwdriver in the slot at the
short edge of the cap. Release the
cap by carefully moving the
screwdriver sidewards. To prevent
damage it is recommended to place a cloth between the screwdriver and
the frame.
The towing eye is stowed with the vehicle tools 3 246.
