● A discharged vehicle battery can
already freeze at a temperature
of 0 °C. Defrost the frozen vehicle
battery before connecting jump
leads.
● Wear eye protection and
protective clothing when
handling a vehicle battery.
● Use a booster vehicle 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
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
vehicle battery.
2. Connect the other end of the red
lead to the positive terminal of the
discharged vehicle battery.
3. Connect the black lead to the
negative terminal of the booster
vehicle 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 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.
