WARNING  
Careless or unsupervised use of the vehicle key can lead to accidents or serious injuries.  
Take all vehicle keys with you when you leave the vehicle. Otherwise, children or  
unauthorised persons could lock the doors and the boot lid, start the engine or switch on  
the ignition and operate electrical equipment, such as the electric windows.  
Never leave children or people requiring assistance alone in the vehicle. They could become  
trapped in the vehicle in an emergency and may not be able to get themselves to safety. For  
example, locked vehicles may be subjected to very high or very low temperatures depending  
on the season. This can cause serious injuries and illness or fatalities, especially among small  
children.
