Approaching A Hill - GMC 2004 Yokon Denali Owner's Manual

Approaching a Hill

When you approach a hill, you need to decide if it is
one of those hills that is 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.
Here are some things to consider as you approach
a hill.
•
Is there a constant incline, or does the hill get
sharply steeper in places?
•
Is there good traction on the hillside, or will the
surface cause tire slipping?

•
Is there a straight path up or down the hill so you
will not have to make turning maneuvers?
•
Are there obstructions on the hill that can block
your path (boulders, trees, logs or ruts)?
•
What is beyond the hill? Is there a cliff, an
embankment, a drop-off, a fence? Get out and walk
the hill if you do not know. It is the smart way to
find out.
•
Is the hill simply too rough? Steep hills often have
ruts, gullies, troughs, and exposed rocks because
they are more susceptible to the effects of erosion.
