WARNING - Low tire pressure

  • Significantly low tire pressure makes the vehicle unstable and can contribute to loss of vehicle control and increased braking distances.
  • Continued driving on tires with low tire pressure can cause the tires to overheat and fail, which may cause an accident.

The TPMS cannot alert you to severe and sudden tire damage caused by external factors.

If you notice any vehicle instability, immediately take your foot off the accelerator pedal, apply the brakes gradually with light force, and slowly move to a safe position off the road.

CAUTION - Low Fuel Level Driving with the Low Fuel Level warning light on or with the fuel level below “E” can cause the engine to misfire and damage the catalytic converter (if equipped).
