Fuses Data on the replacement fuse must
match the data on the defective fuse.
There are three fuse boxes in the
vehicle:
● engine compartment
● instrument panel
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognised by its melted wire.Caution

cause of the fault has been
remedied.
Some functions are protected by
several fuses.
Fuses may also be inserted without
existence of a function.

202Vehicle care9. Connect the compressor plug tothe 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 6 bar whilstthe 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 being
inflated.
13. The prescribed tyre pressure should be obtained within ten
minutes.
Tyre pressure 3 229.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within ten minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
ten 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 on the air hose.
Do not run the compressor longer
than ten minutes.
14. Detach the tyre repair kit. Remove
sealant bottle from bracket. Screw the filler hose to the free
connection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in
load compartment.
15. Remove any excess sealant using a cloth.

204Vehicle care●If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Take heavy objects out of the vehicle before jacking up.
● No people or animals may be in the vehicle when it is jacked-up.
● Never crawl under a jacked-up vehicle.
● Do not start the vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them and lightly coat
the taper of each wheel bolt with
commercially available grease.9 Warning
Do not grease the thread of the
wheel bolt.
1. Disengage wheel bolt caps with a
screwdriver and remove.
Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
bolt caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.
2. Fold out the wheel wrench and install ensuring that it locates
securely and loosen each wheel
bolt by half a turn.
The wheels might be protected by
locking wheel bolts. To loosen
these specific bolts, first attach
the adapter for the locking wheel
bolts onto the head of the bolt
before installing the wheel
wrench. The adapter is located in
the load compartment under the
rear floor cover.
3. Ensure the jack is correctly positioned under the relevant
vehicle jacking point.
4. Set the jack to the necessary height. Position it directly below

208Vehicle care● 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 Volts). Its
capacity (Ah) must not be much less than that of the discharged
vehicle 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
vehicle battery from the vehicle.
● Switch off all unnecessary electrical consumers.
● Do not lean over the vehicle 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 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.
3. Connect the black lead to the negative terminal of the boosterbattery.
4. Connect the other end of the black
lead to a vehicle grounding point
of your vehicle in the engine
compartment.
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.
