Safety FirstOperating instructionsPractical tipsTe c h n i c a l D a t a The vehicles should not touch. Otherwise, current may be allowed to flow
when the positive poles are connected.
Connect the clamps so they have good metal-to-metal contact with the termi-
nals.
If the engine fails to start straight-away, switch off the starter after about 10
seconds and try again after about a minute.
Complete operations only in the sequence given.
Jump lead terminal connections
xSwitch off the ignition of both vehicles Ÿpage 195.
xLikewise, open the battery cover in the engine compartment Ÿpage 318,
or remove the positive pole cap from one side 3), in the direction of the arrow
Ÿpage 372, fig. 225.
xConnect one end of the red jump lead to the positive terminal
Ÿpage 372, fig. 226 or Ÿpage 372, fig. 225 of the vehicle with the
flat battery Ÿ.
xConnect the other end of the red jump lead to the positive terminal in
the vehicle providing assistance .
xFor vehicles without Start-Stop system: Connect one end of the black
jump lead to the negative terminal in the vehicle providing assistance
Ÿpage 372, fig. 226.
xFor vehicles with Start-Stop system: Connect one end of the black
jump lead to a suitable ground connection, a solid piece of metal in the
engine block, or to the engine block Ÿpage 372, fig. 227.
xConnect the other end of the black jump lead to a solid metal compo-
nent connected to the engine block, or onto the engine block itself of the
vehicle with the flat battery however, connect it as far away as possible from
the battery Ÿ.
xPlace the leads so that they cannot be caught by any moving parts in the
engine compartment.Switching on
xStart the engine of the vehicle supplying current and let it run at idling
speed.
xStart the engine of the car with the flat battery and wait two or three
minutes until the engine is “running smoothly”.
Removing the jump leads
xBefore you remove the jump leads, switch off the headlights (if they are
switched on).
xTurn on the heating and rear window heater in the vehicle with the flat
battery. This helps minimise voltage peaks which are generated when the
leads are disconnected.
xWith the engines running, disconnect the leads in reverse order to
connection.
xClose the battery cover, or replace the positive pole cap 3).
WARNING
Incorrectly jump starting could cause the battery to explode resulting in
serious injury. Please observe the following rules to minimise the risk of a
battery explosion:
xAll work involving the vehicle battery and electrical system can cause
corrosion, fire and serious electric shocks. Always read and take into
account the safety warnings and standards before beginning work on the
battery Ÿpage 318, “Vehicle battery”.
xAlways protect your eyes with suitable working goggles and never lean
over the vehicle battery.
xThe jump leads must be connected in the correct order: first the positive
cable, then the negative cable.
xDo not attach the negative cable to parts of the fuel system or to the
brake hose/pipe.
