into the engine compartment to catch fire. You
could be seriously burned.• Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine if
you see or hear steam coming from it.Turn off the engine, get out of the vehicle and do
not stand near the vehicle until it cools down.

of driving for which the vehicle is used. For example,
driving at extreme speeds, and cold starts combined
wi t h short di stan ce d r ivi ng in which the e ngin e d oes not
reach operating normal temperature, reduce the interval
between services.
