Cadillac 2008 CTS - Manual (Page 366)

If a tire goes flat, and your vehicle has a compact spare
tire, see Changing a Flat Tire on page 5-102. This
information shows you how to use your vehicle’s tire
changing equipment and how to change a flat tire safely.
{ CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a flat tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a flat tire.
Tire Sealant and Compressor Kit
If your vehicle has a factory installed tire sealant and
compressor kit, there is no spare tire, no tire changing
equipment and no place to store a tire.
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place and stopping.
1. Turn on the hazard warning flashers. See Hazard
Warning Flashers on page 3-6.
2. Park your vehicle. If your vehicle has an automatic
transmission, set the parking brake firmly and
put the shift lever in PARK (P). See Shifting Into
PARK (P) (Automatic Transmission) on page 2-44.
If your vehicle has a manual transmission, move
the shift lever to REVERSE (R) and set the parking
brake firmly. See Parking Your Vehicle (Manual
Transmission) on page 2-46 for additional
information.
3. Turn off the engine.
4. Inspect the flat tire.
If the tire has been separated from the wheel, has
damaged sidewalls, or has a puncture larger than a
1 ⁄
4
inch (6 mm), the tire is too severely damaged for
the tire sealant and compressor kit to be effective.
See Roadside Service on page 7-6.
If the tire has a puncture less than a 1 ⁄
4
inch (6 mm)
in the tread area of the tire, see Tire Sealant and
Compressor Kit (With Sealant Selector Switch) on
page 5-85 or Tire Sealant and Compressor Kit
(Without Sealant Selector Switch) on page 5-93.
