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.
