How to jump start: description⇒fig. 199    shows the flat battery and   the charged battery.
Jump lead terminal connections
– Switch off the ignition on both vehicles  ⇒.
1.  Connect one end of the red jump lead to the positive  ⇒fig. 199 
 terminal of the vehicle with the flat battery  ⇒.
2.  Connect the other end of the red jump lead to the positive  terminal   in the vehicle providing assistance.
3.  Connect one end of the black jump lead to the negative terminal   on the battery of the vehicle providing assistance. 4.  Connect the other end of the black jump lead   to a solid metal 
component which is bolted on to the engine block, or onto the 
engine block itself of the vehicle with the flat battery. Do not 
connect it to a point near the battery  ⇒.
5.  Position the leads in such a way that they cannot come into  contact with any moving parts in the engine compartment.
Starting
6.  Start the engine of the vehicle  with the boosting battery and let 
it run at idling speed.
7.  Start the engine of the car with the flat battery and wait one or  two minutes until the engine is “running”.
Removing the jump leads
8.  Before you remove the jump leads, switch off the headlights (if  they are switched on).
9.  Turn on the heater blower and rear window heater in the vehicle  with the flat battery. This helps minimise voltage peaks which are 
generated when the leads are disconnected.
10. When the engine is running, disconnect the leads in reverse  order to the details given above.
Connect the battery clamps so they ha ve good metal-to-metal contact with 
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and 
try again after about half a minute.
