Diagram of connections for vehicles
with Start-Stop system. Jump lead terminal connections
1. Switch off the ignition of both vehicles
››› . 2. Connect one end of the
red jump lead to
the po s
itive + terminal of the vehicle
with the flat battery A
››› Fig. 163 .
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 – in the vehicle
providing assistance B
››› Fig. 163 .
– For
vehicles with Start-Stop system: Con-
nect one end of the black jump lead X to a
suitable ground terminal, a solid piece of
metal in the engine block, or to the engine
block itself ››› Fig. 164.
5. Connect 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 vehicle's engine with the boost- ing 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 discon-
nected.
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 163, 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 190
