Batteries

sparks, lighted matches and open flame away from the top of the
battery. If hydrogen gas escaping from the cap vents is ignited, it
will ignite gas trapped in the cells and cause the battery to ex-
plode.

Indicator and warning lights
Many vehicle systems are self-monitored for faults while driv-
ing. Generally,
a red warning lamp that comes on during driv-
ing should be considered serious. If you cannot immediately
determine the seriousness of the warning light, stop the vehi-
cle in a safe place and turn the engine off as soon as possible.
Consult the owner's manual for additional information on the
warning lamp and the recommended action.
If the Malfunction Indicator Lamp (MIL)
(Check Engine or Ser-
vice Engine Soon warning light) comes on orflashes, it indi-
cates that an emissions-related fault has occurred. Faults
such as a bad oxygen sensor or a dead fuel injector can
cause the exhaust or evaporative emissions to exceed a
specified limit. When these limits are exceeded, the MIL will
be turned on. The engine can be safety driven with the light
on, although the emission systems should be
checked as
soon as possible. See OBD On-Board Diagnostics for
