2006 CADILLAC CTS tires

Run-Flat Tires (CTS-V)
If your vehicle has run-at tires, there is no spare tire
and no tire changing equipment. Run-at tires can
operate effectively with no air pressure for a limited
distance and speed. Your vehicle also has a Tire
Pressure Monitor (TPM) which will alert you if there
is a loss of tire pressure in any of the tires. These
tires perform so well without any air pressure that a
Tire Pressure Monitor (TPM) is used to alert you when
there is a low tire condition.
{CAUTION:
When the low tire warning light is displayed on
the instrument panel cluster, your vehicle’s
handling capabilities will be reduced during
severe maneuvers. If you drive too fast, you
could lose control of your vehicle. You or
others could be injured. Do not drive over
55 mph (90 km/h) when the low tire warning
light is displayed. Drive cautiously and check
your tire pressures as soon as you can.SeeRun-Flat Tires (CTS-V) on page 5-64andTire
Pressure Monitor System on page 5-68, for additional
information.
{CAUTION:
Special tools and procedures are required to
service a run-at tire. If these special tools
and procedures are not used you or others
could be injured and your vehicle could be
damaged. Always be sure the proper tools
and procedures, as described in the service
manual, are used.

Ordering Information on page 7-16.

Compact Spare Tire (CTS Only)
Although the compact spare tire 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 your vehicle through an automatic car
wash with guide rails. The compact spare can get
caught on the rails. That can damage the tire
and wheel, and maybe other parts of your 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 your compact spare.
Using them can damage your vehicle and can
damage the chains too. Do not use tire chains on
your compact spare.
Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its best if
it is cleaned often. Although not always visible, dust and
dirt can accumulate on your upholstery. Dirt can
damage carpet, fabric, leather, and plastic surfaces.
Regular vacuuming is recommended to remove particles
from your upholstery. It is important to keep your
upholstery from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible. Your
vehicle’s interior may experience extremes of heat
that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to your home furnishings may also
transfer color to your vehicle’s interior.
When cleaning your vehicle’s interior, only use cleaners
specically designed for the surfaces being cleaned.
Permanent damage may result from using cleaners on
surfaces for which they were not intended. Use glass
cleaner only on glass. Remove any accidental over-spray
from other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.

Notice:Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not
be covered by your warranty. Use chrome polish
on chrome wheels only.
Use chrome polish only on chrome-plated wheels, but
avoid any painted surface of the wheel, and buff off
immediately after application.
Notice:If you drive your vehicle through an
automatic car wash that has silicone carbide tire
cleaning brushes, you could damage the aluminum
or chrome-plated wheels. The repairs would not
be covered by your warranty. Never drive a vehicle
equipped with aluminum or chrome-plated wheels
through an automatic car wash that uses silicone
carbide tire cleaning brushes.
Do not take your vehicle through an automatic car wash
that has silicone carbide tire cleaning brushes. These
brushes can also damage the surface of these wheels.Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on your vehicle may damage the paint
nish and/or tires. When applying a tire dressing,
always wipe off any overspray from all painted
surfaces on your 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 warranty.

At Each Fuel Fill
It is important to perform these underhood checks at
each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 5-16for further
details.
Notice:It is important to check your oil regularly
and keep it at the proper level. Failure to keep your
engine oil at the proper level can cause damage
to your engine not covered by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary.
SeeEngine Coolant on page 5-26for further details.
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 Ination Check
Visually inspect your vehicle’s tires and make sure they
are inated to the correct pressures. Do not forget to
check the spare tire. SeeTires on page 5-57for further
details. Check to make sure the spare tire is stored
securely. SeeChanging a Flat Tire (CTS Only)
on page 5-84.
Tire Wear Inspection
Tire rotation may be required for high mileage highway
drivers prior to the Engine Oil Life System service
notication. Check the tires for wear and, if necessary,
rotate the tires. SeeTire Inspection and Rotation
on page 5-71.
