Windshield Washer Fluid
What to Use
When adding windshield washer uid to the vehicle, 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
uid 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
uid level is low. SeeDIC Warnings and Messages on
page 3-58for more information.
Open the cap with the
washer symbol on it.
Add washer uid until the
tank is full. SeeEngine
Compartment Overview on
page 5-14for reservoir
location.Notice:
When using concentrated washer uid, follow
the manufacturer’s instructions for adding
water.
Do not mix water with ready-to-use washer uid.
Water can cause the solution to freeze and
damage your washer uid tank and other parts
of the washer system. Also, water does not
clean as well as washer uid.
Fill the washer uid tank only three-quarters
full when it is very cold. This allows for uid
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’s
windshield washer system and paint.
5-41

(n)If the vehicle has the 3.6L V6 (Code V) engine,
replace the engine air cleaner filter every 40,000 miles
(64 000 km).
(o)Drain, flush, and refill clutch hydraulic system at a
regular maintenance service every two years. This
service can be complex; you should have your
dealer/retailer perform this service. Change fluid every
25,000 miles (40 000 km) if the vehicle is used for
high performance operation.
(p)Drain, flush, and refill intercooler system. This service
can be complex; you should have your dealer/retailer
perform this service. See Engine Coolant on page 5-32.
(q)Check vent hose at transfer case for kinks and
proper installation. Check to be sure vent hose
is unobstructed, clear, and free of debris. During any
maintenance, if a power washer is used to clean
mud and dirt from the underbody, care should be taken
to not directly spray the transfer case output seals.
High pressure water can overcome the seals and
contaminate the transfer case fluid. Contaminated fluid
will decrease the life of the transfer case and should
be replaced.(r)Change transfer case fluid if the vehicle is mainly
driven under one or more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as high performance operation or taxi,
police, or delivery service.
Owner Checks and Services
These owner checks and services should be performed
at the intervals specied to help ensure vehicle safety,
dependability, and emission control performance. Your
dealer/retailer can assist with these checks and services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to the
vehicle, make sure they are the proper ones, as shown
inRecommended Fluids and Lubricants on page 6-14.

At Each Fuel Fill
It is important to perform these underhood checks at
each fuel fill.
Engine Oil Level Check
Notice:It is important to check the engine oil
regularly and keep it at the proper level. Failure to
keep the engine oil at the proper level can cause
damage to the engine not covered by the vehicle
warranty.
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 5-18.
Coolant Level Check
Check the engine coolant level and, on CTS-V models,
check the intercooler coolant level. Add DEX-COOL®
coolant mixture if necessary. SeeEngine Coolant
on page 5-32.
Windshield Washer Fluid Level Check
Check the windshield washer uid level in the windshield
washer uid reservoir and add the proper uid if
necessary.
At Least Once a Month
Tire Inspection and Ination Check
Inspect the vehicle’s tires for wear and make
sure they are inated to the correct pressures.
SeeInflation - Tire Pressure on page 5-69.

Recommended Fluids and
Lubricants
Fluids and lubricants identied below by name, part
number, or specication can be obtained from your
dealer/retailer.
Usage Fluid/Lubricant
Engine OilThe engine requires a special engine
oil meeting GM Standard GM4718M.
Oils meeting this standard can be
identied as synthetic, and should
also be identied with the American
Petroleum Institute (API) Certied for
Gasoline Engines starburst symbol.
However, not all synthetic API oils
with the starburst symbol will meet
this GM standard. Look for and use
only an oil that meets GM Standard
GM4718M. For the proper viscosity,
seeEngine Oil on page 5-18.
Engine Coolant50/50 mixture of clean, drinkable
water and use only DEX-COOL
