If you drive a cargo van, the spare tire is stored inside the vehicle on the driver's side. If you drive a passenger van, it is stored inside the vehicle behind the rear-most passenger seat. The spare tire is full size, like the other tires on your vehicle.

If your vehicle is not equipped with a spare tire, contact GM Roadside Assistance. See "Roadside Assistance" in the Index of your owner's manual.

Vehicles purchased in Canada have an extensive Roadside Assistance program accessible from anywhere in Canada or the United States. Please refer to the separate brochure provided by the dealer.

Do not remove or replace a tire from/to the storage position inside the vehicle while the vehicle is supported by a jack. Remove the jack and jacking equipment. Refer to "Changing a Flat Tire" in the Index of your owner's manual.

To remove the spare tire, use the wheel wrench to loosen the retaining nut. Then lift off the adapter and remove the spare tire.

The spare tire carrier is removeable to allow clearance for large loads and removing the seats.

To remove the spare tire carrier, do the following:

1. Remove the spare tire. See "Removing the Spare Tire (If Equipped)" previously in this section.
2. Use a tool to loosen and remove the four bolts and washers at the bottom of the spare tire carrier.
3. Remove the spare tire carrier from the vehicle.
4. To reinstall, reverse the steps and tighten the bolts to 50 ft lbs (68 N·m).

Caution: Raising your vehicle with the jack improperly positioned can damage the CNG fuel system and cause a natural gas leak. If the gas is accidentally ignited, you or others could be seriously injured. Never use the CNG fuel system components or fuel lines as lift points.

See "Changing a Flat Tire" in the Index of your owner's manual for the correct front and rear jack positions.

Caution: Storing a jack, a tire or other equipment loosely in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.

Put the flat or spare tire in the mounting position inside the vehicle. Put the adapter in the center of the wheel. Make sure the adapter tab is inserted in the wheel nut hole at the 12 o'clock position for a spare tire and for a flat tire, at the 6 o'clock position. Turn the retainer nut in the hole in the center of the adapter to the right and tighten to 60 ft lbs (80 N·m).
