Oh my lord(baby),

When standing in front of my CTS with the hood open,
the reservoir is on the front left side of the engine compartment
with a windshield washer symbol molded into the yellow-colored filler cap.

2008 CTS Owner's Manual p. 5-39:

Windshield Washer Fluid

What to Use
When you need windshield washer fluid, be sure to
read the manufacturer’ 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
The Washer Fluid Low Add Fluid message will appear
on the Driver Information Center (DIC) when the
fluid level is low. See DIC Warnings and Messages
on page 3-54 for more information.
Open the cap with the
washer symbol on it.
Add washer fluid until the
tank is full. See Engine
Compartment Overview
on page 5-14 for reservoir
location.

Notice:

• When using concentrated washer fluid,
follow the manufacturer’ instructions for
adding water.
• Do not mix water with ready-to-use washer fluid.
Water can cause the solution to freeze and
damage your washer fluid tank and other parts
of the washer system. Also, water does not
clean as well as washer fluid.
• Fill the washer fluid tank only three-quarters full
when it is very cold. This allows for fluid
expansion if freezing occurs, which could
damage the tank if it is completely full.
• Do not use engine coolant (antifreeze) in your
windshield washer. It can damage the vehicle’
windshield washer system and paint.

 

Read your owners manual thats what its for. :-0

 

If refilling washer fluid is beyond you, I'm not so sure you should be operating a vehicle period.

 

It absolutely amazes me all the people who do not take the time to read their owner's manual! Take the time to read it from cover to cover and you just might learn something. When your DIC states that you are "low on fuel" you might know where the fuel filler door is !!

 

Hey, at least he asked. That's much better than adding water and then asking why things froze up.

I may not be normal...but I actually read the owner's manual twice! Once when I first got the vehicle, and then another time about a month later...just to make sure I didn't miss anything.:bouncy:

 

By the way; the fuel gauge has an arrow next to it, to show which side the filler door is on. I thought this may be helpful to you at some time in the future.

 

Somebody should tell him that oil has to be changed and not just "filled in."

Call me an ass, but....dude, who doesn't know who to fill washer fluid? Who doesn't know that you put washer fluid in a car and not water? I mean....come on!

lordbaby, did you have a butler valeting your car for you or something?

 

nah.. this is technically my first car.. and i never added washer fluid myself. Either the dealer add them for me during regular visit or
in the past i had a driver and he took care everything..

 

Wow! Is this a joke?

 

sorry guys, i will look at the instruction manual for sure, thanks for the help

 

maybe you can rehire the driver on at least a temporary basis.

 

(speechless)

 

Use GM Optikleen not water. I find it to be the best streak free solution on the market. Especially on those mid winter sloppy days. You dont need to use as much either. A few sprays usually does it!
