caution not to catch hands or fingers.The radiator fan may continue to run for 
approximately 30 seconds or even restart after the 
engine has been turned off. Stay clear from fan 
blades.

ignition system. Because of the high voltage it is 
dangerous to touch any components (ignition coils, 
spark plug sockets, diagnostic socket) of the 
ignition system
• with the engine running,
• while starting the engine,
• if ignition is “on” and the engine is turned 
manually.If you see flames, steam or smoke coming from the 
engine compartment, or if the coolant temperature 
gauge indicates that the engine is overheated, do 
not open the hood. Move away from vehicle and do 
not open the hood until the engine has cooled. If 
necessary, call a fire department.
