● Apply the parking brake,
transmission in neutral.
● 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 booster
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.
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.
