To activate Automatic mode for de-icing, press the
heated washer switch. The indicator light starts to flash
at a one second rate. Once the washer fluid is
heated, approximately 25 seconds, it is sprayed on the
windshield. This cycle will repeat four times
(approximately every six seconds) and then the unit will
return to Standby mode. Pressing the heated washer
fluid button at any time during this cycle will stop
the Automatic mode and return it to Standby. Automatic
mode is recommended while the vehicle is parked.
In the case of a rapidly flashing light indicator on the
heated washer switch, it may be necessary to wait for up
to one minute for the light to stop flashing, then cycle
the ignition.

If your vehicle has a rear

to the left of the
steering wheel.

CAUTION:
In freezing weather, do not use your washer

washer fluid can form ice on the windshield,
blocking your vision.

For long delayed wiping, turn the knob to 1. For short
delayed wiping, turn the knob to 2.

The rear window washer uses the same fluid reservoir
as the windshield washer. However, the rear window
washer will run out of fluid before the windshield washer.
If you can wash your windshield but not your rear
windows, check the fluid level.
