Problems at High Altitudes

When driving at high altitudes, remember the following:

  • Thin mountain air can affect your car's engine and diminish your acceleration and climbing power
  • The potential for overheating is greater
  • The potential for vapor locks is greater

During very hot weather, gasoline can simmer or boil and turn to a vapor, developing a condition called vapor lock. Your engine stops running or locks up. If your engine becomes vapor locked, turn it off and let it cool.
