CAUTION
. To prevent the battery from being
discharged, do not operate the
defogger and deicer system con-
tinuously for any longer than
necessary.
. Do not use sharp instruments or
window cleaner containing abra-
sives to clean the inner surface
of the rear window. They may
damage the conductors printed
on the window.
NOTE . Turn on the defogger and deicer
system if the wipers are frozen to the windshield.. If the windshield is covered with
snow, remove the snow so that the
windshield wiper deicer works effec-
tively.. While the defogger and deicer sys-
tem is in the continuous operation
mode, if the vehicle speed remains at
9 mph (15 km/h) or less for 15 minutes,
the windshield wiper deicer automati-
cally stops operating, though the rear
window defogger and outside mirror
defogger maintain continuous opera-
tion in this condition. Tilt/telescopic steering wheel

gerous to drive without locking
the steering wheel. This may
cause loss of vehicle control
and result in personal injury.
