use the same method to help start  
another vehicle. Use only jumper cables  
with fully-insulated clamp handles.  
Preparing  
1. Check whether the battery of the  
other vehicle has a voltage of  
12 Volts and approximately the same  
capacitance in Ah. This information  
can be found on the battery

vehicle

fatal injury, always avoid all con-  
tact with electrical components while  
the engine is running. Carefully observe  
the following instructions to avoid per-

3. Switch off any electrical systems and  
components in both vehicles.  
Ensure that no contact exists  
between the bodywork on the two  
vehicles, otherwise there is a danger of  
short circuits.<
