NOTICE:
When cleaning the glass, use a soft, dry cloth and wipe the
glass in the direction of the wire. Take care not to damage
the wires.Do not use detergents or glass cleaners with
abrasive ingredients.When measuring voltage, wind a
piece of tin foil around the top of the negative ( −) probe and
press the foil against the wire with your finger, as shown.
(a) Turn the ignition switch ON.
(b) Turn the defogger switch ON.
