Preparations
Ob
serve the following information when
carrying out jump starting:
✓ Wear suitable eye protection and pro-
tective gloves →
.
✓ Ob
serve the jump lead manufacturer’s
instructions.
✓ Open the bonnet.
✓ Always use jump leads with fully insula-
ted terminal clamps and intact insula-
tion for jump starting →
.
✓ Ensure tha
t there is sucient distance
between the vehicle giving the jump
start and the vehicle receiving the jump
start, as any contact could mean that
electricity could flow as soon as the
positive battery terminals are connec-
ted.
✓ Ensure that the battery clamps have
good metal-to-metal contact with the
battery terminals.
Jump leads
Suitable jump leads are required to provide
and receive jump starts.
The cable cross-section of the jump leads
must be at least 25 mm
2
(0.038 in
2
).
For vehicles with a diesel engine, the cable
cross-section of the jump leads must be at
least 35 mm
2
(0.054 in
2
).
Vehicle receiving jump starting assis-
tance
1. Check that the discharged 12-volt vehi-
cle battery is properly connected to the
12-volt electrical system.
2. If the fitted 12-volt vehicle battery has
a battery window, check the colour of
the window. If the battery window is
light yellow or colourless, do not jump
start the vehicle. Seek expert assis-
tance.
Vehicle providing jump starting assis-
tanc
e
1. Observe the owner’s manual issued by
the vehicle manufacturer.
2. Check that the vehicle battery providing
assistance has the same voltage
(12 volts) and approximately the same
capacity as the discharged 12-volt vehi-
cle battery. Check the label on the vehi-
cle battery of the vehicle giving the
jump start.
WARNING
Jump starting the vehicle incorrectly can
c
ause the 12-volt vehicle battery to ex-
plode, which can lead to serious injuries or
death.
·
Always wear suitable eye protection
and protective gloves.
·
Never bend over the 12-volt vehicle bat-
tery.
·
Always connect the positive cable first,
followed by the negative cable.
·
Never connect the negative lead to
parts of the fuel system or to the brake
lines.
·
Make sure that there is no contact be-
tween the non-insulated parts of the
terminal clamps.
·
Make sure that the cable insulation is
intact.
·
Ensure that the lead attached to the
positive terminal on the 12-volt vehicle
battery does not touch any electrically
conductive parts of the vehicle.
