General points on starting
If the battery has been disconnected the vehicle may exhibit some unusual driving characteristics for approx. 8 kilometres (5 miles) after reconnecting the battery.
This is because the engine management system must realign itself with the engine.
Any unusual driving characteristics during this period may be disregarded.
