Oldsmobile 2003 Bravada Owner's Manual page 229

For reasons like these, you need to decide carefully
whether to try to drive across an incline. Just because
the trail goes across the incline doesn't mean
YOU
have to drive it. The last vehicle to try it might have
rolled over.
Driving across an incline that's too steep will
make your vehicle roll over. You could be
seriously injured or killed. If you have any
doubt about the steepness of the incline, don't
drive across it. Find another route instead.
Q:
What if I'm driving across an incline that's not
too steep, but I hit some loose gravel and start
to slide downhill. What should I do?
A:
If you feel your vehicle starting to slide sideways,
turn downhill. This should help straighten out the
vehicle and prevent the side slipping. However,
a much better way to prevent this
is
to get out and
"walk the course" so you know what the surface
is like before you drive it.
Stalling on an Incline
If your vehicle stalls when you're crossing an incline, be
sure you (and your passengers) get out on the uphill
side, even if the door there is harder to open. If you get
out on the downhill side and the vehicle starts to roll I
over, you'll be right in its path.
If you have to walk down the slope, stay out of the path
the vehicle will take if it does roll over.
