3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the fluid level on
the dipstick.
The level should be at the FULL COLD mark.

Windshield Washer Fluid

What to Use
When you need windshield washer fluid, be sure to
read the manufacturer's instructions before use. If you
will be operating your vehicle in an area where the
temperature may fall below freezing, use a fluid that has
sufficient protection against freezing.

Adding Washer Fluid

Your vehicle has a low washer fluid message that
comes on when the washer fluid is low. The message is
displayed for 15 seconds at the start of each ignition
cycle. When the CHECK WASHER FLUID message is
displayed, you will need to add washer fluid to the
windshield washer fluid reservoir.
