Driving On Hills; Approaching A Hill - GMC Hummer H3 2008 Owner's Handbook Manual

Starting and Operating Instructions

DRIVING ON HILLS

Off-road driving often takes you
up, down or across a hill. Driving
safely on hills requires good judge-
ment and an understanding of
what your vehicle can and can't
do. There are some hills that
simply can't be driven, no matter
how well built the vehicle.

CAUTION
Many hills are simply too steep
for any vehicle. If you drive up
them, you will stall. If you drive
down them, you can't control
your speed. If you drive across
them, you will roll over. You
could be seriously injured or
killed. If you have any doubt
about the steepness, don't
drive the hill.

APPROACHING A HILL

When you approach a hill, you
need to decide if it's one of those
hills that's just too steep to climb,
descend or cross. Steepness can be
hard to judge. On a very small hill,
for example, there may be a
smooth, constant incline with only
a small change in elevation where
you can easily see all the way to
the top. On a large hill, the incline
may get steeper as you near the
top, but you may not see this
because the crest of the hill is
hidden by bushes, grass or shrubs.
