Vehicle care195●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
for
diesel engines).
● Do not disconnect the discharged
battery from the vehicle.
● Switch off all unnecessary electrical consumers. The
Infotainment system may be
damaged if switched on while jump starting.
● 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 electrical parking brake
3 143, transmission in neutral,
automatic transmission in P.
● Open the positive terminal protection caps of both batteries.
Lead connection order:
1. Connect the red lead to the positive terminal 1 of the booster
battery.
2. Connect the other end of the red lead to the positive terminal 2 of
the discharged battery.
3. Connect the black lead to the negative terminal 3 of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block 4 or an
engine mounting bolt. Connect as far away from the discharged
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 start.
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.
4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
