Important: Use of the compact spare may result in activating a wheel sensor fault code. This will result in an Antilock warning lamp turning on and deactivation of the antilock brake system. After replacing the compact spare, the recycling ignition switch will reset the system.

Notice: If the compact spare is used as a rear tire, do not drive faster than 80 km/h (50 mph). Damage to the rear axle may occur if the compact spare is driven faster than 80 km/h (50 mph). This speed limitation does not apply when the compact spare is used as a front tire.

Some vehicles are equipped with a high-pressure compact spare. The compact spare uses a narrow 4 inch wide rim, although the wheel diameter is usually one inch larger than the road wheels.

Notice: The compact spare wheel should not be used with standard tires, snow tires, wheel covers or trim rings. If such use is attempted, damage to these items or other parts of the vehicle may occur. The compact spare should be used only on vehicles that offer it as original equipment.

Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 220 kPa (32 psi) pressure when inflating any tire if beads are not seated. If 220 kPa (32 psi) pressure will not seat the beads, deflate, relubricate the beads and reinflate. Overinflation may cause the bead to break and cause serious personal injury.

Measure the compact spare inflation pressure periodically and maintain the inflation pressure at 420 kPa (60 psi). You can mount or dismount the tire from the wheel using present tire-changing equipment procedures. As with other tires, the beads should completely seat at 280 kPa (40 psi).

Notice: Do not take the vehicle through an automatic car wash with the compact spare installed. The vehicle may get caught, which could result in property damage.

The compact spare weighs less than standard tires and handles more easily when the need arises. Measure the inflation pressure as soon as is practical after installing the compact spare. Adjust the pressure to 420 kPa (60 psi). Only an authorized tire dealer should replace a compact spare.
