Vehicle care151
Set the rocker switch on the
compressor to I. The tyre is filled
with sealant.
10. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
11. All of the sealant is pumped into the tyre. Then the tyre is inflated.
12. The prescribed tyre pressure should be obtained within
10 minutes.
Tyre pressure 3 172.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
10 minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button over the pressure indicator.
Depending on version the button
can be located on the air hose.
Do not run the compressor longer
than 10 min.
13. Detach the tyre repair kit. Push catch on bracket to remove
sealant bottle from bracket. Screw the tyre inflation hose to the freeconnection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in

Vehicle care157Jump starting
Do not start with a quick charger.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle 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 vehicle battery canalready 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 V). 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
.
● Do not disconnect the discharged
vehicle 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.
● Open the positive terminal protection caps of both vehicle
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.

158Vehicle care3. 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
vehicle 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 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of 1 minute.
3. Allow both engines to idle for approx. 3 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 The towing eye is stowed with the
vehicle tools 3 142.
1. Wrap a cloth around the tip of a flat
screwdriver to prevent paint
damage. Disengage cap by using
the screwdriver and remove the
cap.
