Compact Spare Tire
If your vehicle is equipped with a compact spare tire it
was fully inated when the vehicle was new, it can
lose air after a time. Check the ination pressure
regularly. It should be 60 psi (420 kPa).
After installing the compact spare on the vehicle, stop as
soon as possible and make sure the spare tire is correctly
inated. The compact spare is made to perform well at
speeds up to 65 mph (105 km/h) for distances up to
3,000 miles (5 000 km), so you can nish your trip and
have the full-size tire repaired or replaced at your
convenience. Of course, it is best to replace the spare
with a full-size tire as soon as possible. The spare tire will
last longer and be in good shape in case it is needed
again.
Notice:When the compact spare is installed, do not
take the vehicle through an automatic car wash with
guide rails. The compact spare can get caught on the
rails which can damage the tire, wheel and other
parts of the vehicle.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or wheel with
other wheels or tires. They will not t. Keep the
spare tire and its wheel together.
Notice:Tire chains will not t the compact spare.
Using them can damage the vehicle and can damage
the chains too. Do not use tire chains on the
compact spare.

Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on the vehicle may damage the paint nish
and/or tires. When applying a tire dressing, always
wipe off any overspray from all painted surfaces
on the vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to parts repaired or
replaced to restore corrosion protection.
Original manufacturer replacement parts will provide the
corrosion protection while maintaining the vehicle
warranty.
Finish Damage
Any stone chips, fractures or deep scratches in the nish
should be repaired right away. Bare metal will corrode
quickly and may develop into major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer/retailer. Larger
areas of nish damage can be corrected in your
dealer’s/retailer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are not
removed, corrosion and rust can develop on the
underbody parts such as fuel lines, frame, oor pan,
and exhaust system even though they have corrosion
protection.
At least every spring, ush these materials from the
underbody with plain water. Clean any areas where mud
and debris can collect. Dirt packed in close areas of the
frame should be loosened before being ushed. Your
dealer/retailer or an underbody car washing system can
do this.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on the vehicle. This damage can
take two forms: blotchy, ring-shaped discolorations, and
small, irregular dark spots etched into the paint surface.
Although no defect in the paint job causes this, we will
repair, at no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs rst.

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.

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).

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.
