Windshield Wipers
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
gently loosen or thaw them. Damaged wiper blades
may not clear the windshield well, making it harder to
see and drive safely. If the blades do become damaged,
install new blades or blade inserts. For more information,

Sensors
The solar sensor on the vehicle monitors the solar
heat and the air inside of the vehicle. This information is
used to maintain the selected temperature by initiating
needed adjustments to the temperature, the fan speed,
and the air delivery system. The system may also supply
cooler air to the side of the vehicle facing the sun. The
recirculation mode will also be activated, as necessary.
Do not cover the solar sensor located in the center of the
instrument panel, near the windshield, or the system will
not work properly.

the defogger will only run for approximately 20 minutes
before turning off. The defogger can also be turned off by
pressing the button again or by turning off the engine.
Do not drive the vehicle until all the windows are clear.Notice:Do not use a razor blade or sharp object to
clear the inside rear window. Do not adhere anything
to the defogger grid lines in the rear glass. These
actions may damage the rear defogger. Repairs

adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of the vehicle more
effectively.
If the vehicle has a passenger compartment air lter
and the airow seems low when the fan is at the
highest setting it may need to be replaced. For more
