switch the vehicle off and wait 20 minutes, then disconnect the negative lead, then disconnect the positive lead, then using a jump lead (piece of wire that has two crocodile clips) join the positive and negative leads together and leave them for 15 minutes. do not connect the jump lead to any terminals that are still connected to the battery

after 15 minutes remove the jump lead (crocodile clips) and reconnect the positive lead to the battery terminal and tighten up, then reconnect the negative lead to the battery and tighten up. start up the engine and turn the steering full lock left, hold for 3 seconds then full lock right, hold for 3 seconds, then full lock left again and hold for 3 seconds.
