2006 CADILLAC CTS overheating

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your GM Warranty booklet for details. For additional
information refer to the tire manufacturer’s booklet
included with your vehicle’s Owner’s Manual.
{CAUTION:
Poorly maintained and improperly used
tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out and
a serious accident. SeeLoading Your
Vehicle on page 4-32.
Underinated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
CAUTION: (Continued)
CAUTION: (Continued)

Overinated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents.
If your tread is badly worn, or if your
tires have been damaged, replace them.
SeeInflation - Tire Pressure on page 5-65
for ination pressure adjustment for high
speed driving.
Notice:If your vehicle has 245/45R18, P245/45ZR18
or P225/50R18 size tires, they are classied as
low-prole tires. Low-prole tires are more
susceptible to damage from road hazards or curb
impact than standard prole tires. Tire and or
wheel assembly damage can occur when coming
into contact with road hazards like, potholes, or
sharp edged objects or when sliding into a curb.
Your GM warranty does not cover this type of
damage. Keep tires set to the correct ination
pressure and when possible avoid contact with
curbs, potholes and other road hazards.
