Do not use a rapid charging device to start the vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jump
leads. Observe the following points:
R
The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or a jump-starting device.
R
Vehicles with a petrol engine: only jump-start the vehicle when the engine and exhaust
system are cold.
R
Do not start the engine if the battery is frozen. Let the battery thaw first.
R
Jump-starting may only be performed using batteries with a nominal voltage of 12 V.
R
Only use jump leads that have a sufficient cross-section and insulated terminal clamps.
R
If the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the empty battery a little.
R
Make sure that the two vehicles do not touch.
Make sure that:
R
The jump leads are not damaged.
R
Non-insulated parts of the terminal clamps do not come into contact with other metal parts
while the jump leads are connected to the battery.
R
The jump leads cannot come into contact with parts which can move when the engine is
running, such as the V-belt pulley or the fan.
