2009 CADILLAC CTS oil

The proper replacement parts, uids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 6-14andMaintenance Replacement Parts
on page 6-16. When the vehicle is serviced, make sure
these are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of genuine
parts from your dealer/retailer.
Scheduled Maintenance
To maintain the ride, handling, and performance
of this vehicle, it is important that the rst tire rotation
service be performed when the vehicle has 5,000
to 8,000 miles (8 000 to 13 000 km). Check tires for
ination pressures and wear. SeeTires on page 5-61.
Rotate tires. SeeTire Inspection and Rotation on
page 5-76and “Tire Wear Inspection” inAt Least
Once a Month on page 6-11.When the Change Engine Oil Soon message displays in
the Driver Information Center (DIC), service is required
for the vehicle. Have the vehicle serviced as soon
as possible within the next 600 miles (1 000 km).
It is possible that, if driving under the best conditions,
the engine oil life system may not indicate that
vehicle service is necessary for over a year. However,
the engine oil and lter must be changed at least once
a year and at this time the system must be reset.
Your dealer/retailer has trained service technicians
who will perform this work using genuine parts and
reset the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 5-21for information on the Engine
Oil Life System and resetting the system.
6-4

When the Change Engine Oil Soon message appears,
the following services, checks, and inspections are
required:
❑Change engine oil and lter. SeeEngine Oil on
page 5-18. Reset oil life system. SeeEngine Oil Life
System on page 5-21.An Emission Control Service.
❑Visually check for any leaks or damage.
See footnote (k).
❑Inspect engine air cleaner lter. If necessary, replace
lter. SeeEngine Air Cleaner/Filter on page 5-25.
See footnote (l).
❑Rotate tires and check ination pressures and wear.
SeeTire Inspection and Rotation on page 5-76and
“Tire Wear Inspection” inAt Least Once a Month on
page 6-11.❑Inspect brake system.See footnote (a).
❑Check engine coolant and windshield washer uid
levels and add uid as needed.
❑Perform any needed additional services.
See “Additional Required Services” in this
section.
❑Inspect suspension and steering components.
See footnote (b).
❑Inspect engine cooling system.See footnote (c).
❑Inspect wiper blades.See footnote (d).
❑Inspect restraint system components.
See footnote (e).
❑Lubricate body components.See footnote (f).
6-5

(f)Lubricate all key lock cylinders. Lubricate all body door
hinges. Lubricate all hinges and latches, including those
for the hood, rear compartment, console door, and any
folding seat hardware. More frequent lubrication may be
required when exposed to a corrosive environment.
Applying silicone grease on weatherstrips with a clean
cloth will make them last longer, seal better, and not stick
or squeak.
(g)If driving regularly under dusty conditions, the filter
may require replacement more often.
(h)Change automatic transmission fluid and filter 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.(i)Drain, flush, and refill cooling system. This service can
be complex; you should have your dealer/retailer perform
this service. See Engine Coolant on page 5-32 for what to
use. Inspect hoses. Clean radiator, condenser, pressure
cap, and filler neck. Pressure test the cooling system and
pressure cap.
(j)If using DOT-4 brake fluid only: Drain, flush, and refill
brake hydraulic system at a regular maintenance service
every two years. This service can be complex; you should
have your dealer/retailer perform this service. See Brakes
on page 5-42.
(k)A fluid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the fluid level checked. Add fluid if needed.
(l)If driving regularly under dusty conditions, inspect the
filter at each engine oil change.
(m)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.
6-9

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.

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.
