178 Vehicle care
■ A discharged battery can already
freeze at a temperature of 0 °C.
Defrost the frozen battery before
connecting jump leads.
■ Wear eye protection and protective
clothing when handling a battery.
■ Use a booster battery with the
same voltage (12 Volts). Its
capacity (Ah) must not be much
less than that of the discharged
battery.
■ Use jump leads with insulated
terminals and a cross section of at
least 16 mm 2 (25 mm 2
engines).
■ Do not disconnect the discharged
battery from the vehicle.
■ Switch off all unnecessary electrical
consumers.
■ Do not lean over the 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.

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
battery as possible, however at
least 2 ft.
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 5 minutes, start the other
engine. Start attempts should be
made for no longer than 15
seconds at an interval of 1 minute.
3. Allow both engines to idle for
approx. 3 minutes with the leads
connected.
