iIntermittent wiping is interrupted when
the vehicle is at a standstill and a door
is opened.
!Do not leave windshield wipers in inter-
mittent setting when vehicle is taken to
an automatic car wash or during wind-
shield cleaning. Wipers will operate in
the presence of water sprayed on the
windshield, and wipers may be dam-
aged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass and/or damage the wiper blades
when wiping occurs on a dry wind-
shield.

partment through the air vents in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burn or frostbite on unprotected skin
in the immediate area of the air vents. Al-
ways keep sufficient distance between un-
protected parts of the body and the footwell
air vents. If necessary, change the air flow
using the air distribution controls to direct
the air away from the footwell air vents
(page 177).
