GMC 2003 Envoy - Manual (Page 253)

When you approach a hill^ you need to decide it il's one
of those hills that’s just too stgep to climbs descend
or СГ0Й5. Steepness can he tiard to judge^ On a very
small hill, for ejiample, there may be a smooth, constant
incline ih/ilh only и smatl change in elevation inhere
you can easily see all the way lo the top. On a large hill,
the incline may get steeper as you near Ihe top, bul
yo(j may nol see this because the crest of tha hell
is hidden by bushes, grass or shrubs.
Here are some other things to consider as you
approach a htll.
* Es there a constant Incline, or does Ihe hill get
sharply steeper in places'?
* Es there good traction on Ihe hillside, or will tho
Surface cause tire sHppIr^gT
* Is there a straight path up or down the hill sc you
won1 have to make turning maneuvers?
* Are Ihere obstructions on ihe hill that can block
your path (boulders, trees, logs or rutsj?
* Whars beyond the hlH? Js there э ciiii, зп
embankment, a drop-ott, a fence? Gel out and walk
Iho hill it you don^t know. It's the smart way to
lind OuL
* Is the hill simply loo rough? Sleep hills often have
mis, gullies, troughs and eirposed rocks because
I hey are more susceptible to the effects of erosion.
Approaching a Hill
Once you docidp you can safely drive up the hill, you
need lo lake some special steps.
* Use a low gear and gat a tirm grip on the steenng
wheel
* Get a smoolh start up the hill and try to mainlain
your speed. Don't use mane power Ihan you
need, because you don't want your wheels lo start
spinn^ng or sliding,
* Try lo drive straighi op the hlil IF at ali possibie. It
tha path twists and turns, you might want to find
another roule.
Driving Uphill
Turning or driving across steep hills can be
dangerous. 'Vau could lose traction, slide
sideways, and possibly roll over. You could be
seriously injured or killed- When driving up
hills, always try to go straight up.
