z Do not disconnect the discharged
battery from the vehicle.
z Switch off all unnecessary electrical
consumers.
z Do not lean over the battery during jump
starting.
z Do not allow the terminals of one lead
to touch those of the other lead.
z Apply handbrake. Transmission in
neutral (automatic transmission in P,
Easytronic in N).
Connect the leads in the order shown in the
illustration:
1. Connect one end of the first jump lead
to the positive terminal 1 of the battery
providing the jump start (identified by
"+" sign on battery case or terminal).
2. Connect the other end of this lead to the
positive terminal 2 of the discharged
battery ("+" sign).
3. Connect the first end of the other jump
lead to the negative terminal 3 of the
battery providing the start ("–" sign).
4. Connect the other end of the second
jump lead 4 to ground on the other
vehicle, e.g. engine block or screw
connection in the engine suspension.
z Do not connect leads to negative
terminal of discharged battery!
z The connection point should be as far
away from the discharged battery as
possible.
z Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
z The engine of the vehicle providing the
jump start can be allowed to run during
starting. Attempts to start the engine of
the vehicle with the discharged battery
should be made at intervals of one
minute and should not last longer than
15 seconds. After starting, allow both
engines to idle for approx. 3 minutes with
the leads still connected.
z In order to avoid excess voltage in the
electrical system, before removing a
lead, switch on an electrical consumer
(e.g. light, heated rear window) in the
vehicle receiving the jump start.
z Reverse above sequence exactly when
removing leads.
