Linked mirror function when reversing

When used in cold weather during reverse driving, the door mirror could be frozen and
may not automatically point the mirror surface downward. In this event, remove any ice
and snow from the mirror surface.

Warming the windshield to allow frozen wipers to be moved

Use the windshield wiper de-icer to help prevent the windshield wiper blades from
freezing to the windshield.
Select the [Deicer] switch on the option screen.

The windshield wiper de-icer will automatically turn off after a period of time.

WARNING

Do not touch the lower part of the windshield or parts along the front pillars when the
windshield wiper de-icer is on, as they will be hot and may cause burns.
