WARNING   WARNING:  The tire pressure monitoring system is not a substitute for manually checking tire pressures. You should periodically check tire pressures using a pressure gauge. Failure to correctly maintain tire pressures could increase the risk of tire failure, loss of control, vehicle rollover and personal injury.
WARNING   WARNING:  If the tire pressure monitor sensor becomes damaged it may not function.

Note:   You should only use tire sealants in roadside emergencies as they may cause damage to the tire pressure monitoring system sensor.
Note:   The tire pressure monitoring system indicator light illuminates when the spare tire is in use. To restore the full function of the monitoring system, all road wheels equipped with tire pressure monitoring sensors must be mounted on the vehicle.
If you get a flat tire when driving, do not apply the brake heavily. Instead, gradually decrease your speed. Hold the steering wheel firmly and slowly move to a safe place on the side of the road.
Have a flat serviced by an authorized dealer in order to prevent damage to the tire pressure monitoring system sensors.  See   Tire Pressure Monitoring System.  Replace the spare tire with a road tire as soon as possible. During repairing or replacing of the flat tire, have the authorized dealer inspect the tire pressure monitoring system sensor for damage.
Dissimilar Spare Wheel and Tire Assembly Information
WARNING   WARNING:  Failure to follow these guidelines could result in an increased risk of loss of vehicle control, injury or death.

If you have a dissimilar spare wheel and tire, then it is intended for temporary use only. This means that if you need to use it, you should replace it as soon as possible with a road wheel and tire assembly that is the same size and type as the road tires and wheels that were originally provided by us. If the dissimilar spare tire or wheel is damaged, it should be replaced rather than repaired.
A dissimilar spare wheel and tire assembly is defined as a spare wheel and tire assembly that is different in brand, size or appearance from the road tires and wheels and can be one of three types:
1. T-type mini-spare: This spare tire begins with the letter T for tire size and may have Temporary Use Only molded in the sidewall.
2. Full-size dissimilar spare with label on wheel: This spare tire has a label on the wheel that states: THIS WHEEL AND TIRE ASSEMBLY FOR TEMPORARY USE ONLY.
When driving with one of the dissimilar spare tires listed above, do not:
  • Exceed 50 mph (80 km/h).
  • Load the vehicle beyond maximum vehicle load rating listed on the Safety Compliance Label.
  • Tow a trailer.
  • Use snow chains on the end of the vehicle with the dissimilar spare tire.
  • Use more than one dissimilar spare tire at a time.
  • Use commercial car washing equipment.
  • Try to repair the dissimilar spare tire.
Use of one of the dissimilar spare tires listed above at any one wheel location can lead to impairment of the following:
  • Handling, stability and braking performance.
  • Comfort and noise.
  • Ground clearance and parking at curbs.
  • Winter weather driving capability.
  • Wet weather driving capability.
  • All-wheel driving capability
3. Full-size dissimilar spare without label on wheel
When driving with the full-size dissimilar spare wheel and tire assembly, do not:
  • Exceed 70 mph (113 km/h).
  • Use more than one dissimilar spare wheel and tire assembly at a time.
  • Use commercial car washing equipment.
  • Use snow chains on the end of the vehicle with the dissimilar spare wheel and tire assembly.
The usage of a full-size dissimilar spare wheel and tire assembly can lead to impairment of the following:
  • Handling, stability and braking performance.
  • Comfort and noise.
  • Ground clearance and parking at curbs.
  • Winter weather driving capability.
  • Wet weather driving capability.
  • All-wheel driving capability
When driving with the full-size dissimilar spare wheel and tire assembly additional caution should be given to:
  • Towing a trailer.
  • Driving vehicles equipped with a camper body.
  • Driving vehicles with a load on the cargo rack.
Drive cautiously when using a full-size dissimilar spare wheel and tire assembly and seek service as soon as possible.
