Windshield Washer Fluid - GMC Yukon 2007 Owner's Manual

How to Check Power Steering Fluid
To check the power steering fluid, do the following:
1. Turn the key off and let the engine
compartment cool down.
2. Wipe the cap and the top of the reservoir
clean.
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. If
necessary, add only enough fluid to bring the level
up to the mark.
What to Use
To determine what kind of fluid to use, see
Recommended Fluids and Lubricants on page 588.
Always use the proper fluid. Failure to use the
proper fluid can cause leaks and damage hoses
and seals.

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 in
the DIC 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
WASHER FLUID LOW ADD FLUID message is
displayed, you will need to add washer fluid to the
windshield washer fluid reservoir.
