Its been said that most car companies make it so where airbags deploy based on the impact. It is said that the airbag will not deploy until the impact generates 7 G's of force.

For better traction in sand, drop air pressure 10-12 pounds below normal pressure on conventional tires. (Return to normal pressure after use in these conditions.) Try high-range 4WD to maintain forward momentum. Depending on the condition of the sand, low-range 4WD and alternative gear selections may be necessary.ake sure your battery is fastened, all hoses are in good condition and oil and fluids are topped off, including fuel. Also be sure that all four tires are in good condition and have the proper tire pressure. Avoid travelling alone, especially into unfamiliar territory.
