Advice
Check after 10 minutes of driving Screw in the inflator tube
››› Fig. 163 5 again and check the pressure on the gauge
6 .
1.3 bar (19 psi / 130 kPa) and lower:
● Stop the vehicle! The tyre cannot be sealed
sufficiently with the tyre mobility set.
● You should obtain professional assistance
››› .
1.4 bar (20 psi / 140 kPa) and higher:
● Set the tyre pressure to the correct value
again.
● Carefully resume your journey until you
reach the nearest specialised workshop with-
out exceeding 80 km/h (50 mph).
● Have the damaged tyre replaced. WARNING
Driving with an unsealed tyre is dangerous
and can cause accidents and serious injury.
● Do not continue driving if the tyre pressure
is 1.3 bar (19 psi / 130 kPa) and lower.
● Seek specialist assistance. Jump-starting
Jump leads The jump lead must have a sufficient wire
cross section.
If the engine fails to start because of a dis-
charged battery, the battery can be connec-
ted to the battery of another vehicle to start
the engine.
Jump leads
Jump leads must comply with standard
DIN
72553 (see cable manufacturer's instruc-
tion s).
The wire cross section must be at least
25 mm 2
for petrol engines and at least
35 mm 2
for diesel engines. Note
● The vehicles must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected.
● The discharged battery must be properly
connected to the on-board network. How to jump start: description

Emergencies
2. Connect one end of the red jump lead to
the po s
itive + terminal of the vehicle
with the flat battery A
››› Fig. 164 .
3. C
onnect the other end of the red
jump
lead to the positive terminal + in the ve-
hicle providing assistance B .
4. For vehicles without Start-Stop system:
connect one end of the black jump lead to
the negative terminal – of the vehicle
providing the current B
››› Fig. 164 .
– For
vehicles with Start-Stop system: con-
nect one end of the black jump lead X to a
suitable ground terminal, to a solid piece of
metal in the engine block, or to the engine
block itself ››› Fig. 165 .
5. C
onnect the other end of the black jump
lead X to a solid metal component bolted
to the engine block or to the engine block
itself of the vehicle with the flat battery.
Do not connect it to a point near the bat-
tery A .
6. Position the leads in such a way that they cannot come into contact with any moving
parts in the engine compartment.
Starting
7. Start the engine of the vehicle with the boosting battery and let it run at idling
speed. 8. Start the engine of the vehicle with the flat
battery and wait 2 or 3 minutes until the
engine is “running”.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped beam headlights (if they
are switched on).
10. Turn on the heater blower and heated rear window in the vehicle with the flat
battery. This helps minimise voltage peaks
which are generated when the leads are
disconnected.
11. When the engine is running, disconnect
the l e
ads in reverse order to the details
given above.
Connect the battery clamps so they have
good metal-to-metal contact with the battery
terminals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about a minute. WARNING
● Please note the safety warnings referring to
working in the engine compartment
››› page 166, Working in the engine compart-
ment.
● The b att
ery providing assistance must have
the same voltage as the flat battery (12 V)
and approximately the same capacity (see imprint on battery). Failure to comply could
result in an explosion.
●
Never use jump leads when one of the bat-
teries is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
away from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufacturer of the jump leads.
● Do not connect the negative cable from the
other vehicle directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion.
● Do not attach the negative cable from the
other vehicle to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult in chemical burns. » 189
