Sun visors
To block out glare, swing down the visors.
To use the sun visor at a side window,
swing it down and move it sideways.
& Sun visor extension plate
With the sun visor positioned over the side
window, you can use the sun visor
extension plate to prevent glare through
the gap between the sun visor and center
pillar. To use the extension plate, pull it
toward the rear of the vehicle. When you
have finished using it, stow it by pushing it
toward the front of the vehicle.
CAUTION
Do not pull out the extension plate
with the sun visor positioned over
the windshield. The extension plate
would obstruct your view of the
rearview mirror.
& Vanity mirror with light
CAUTION
Keep the vanity mirror cover closed
while the car is being driven to avoid
dazzle.
