Chevrolet 1994 Astro Passenger Owner's Manual page 163

An emergency like this requires close attention and a quick decision. If you
are holding the steering wheel at the recommended 9 and 3 o'clock
positions, you can turn it a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and just as quickly
straighten the wheel once you have avoided the object.
The fact that such emergency situations are always possible is a good reason
to practice defensive driving at all times and wear safety belts properly.
Off-Road Recovery
You may find sometime that your right wheels have dropped off the edge of
a road onto the shoulder while you're driving.
If the level of the shoulder is only slightly below the pavement, recovery
should be fairly easy. Ease off the accelerator and then, if there is nothing in
the way, steer so that your vehicle straddles the edge of the pavement. You
can turn the steering wheel up to 1/4 turn until the right front tire contacts the
pavement edge. Then
turn
your steering wheel to go straight down the
roadway.
