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.
Starting the engine by towing or pushing
WARNING:
To prevent damage you must not push or tow start your vehicle. Use booster cables and a booster battery. See Using booster cables.
