Operating Your All-Wheel-Drive Vehicle Off Paved Roads - Cadillac GMC Yukon Denali 2005 Owner's Manual

If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you
will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try your
best to avoid sudden steering, acceleration, or braking,
including engine braking by shifting to a lower gear. Any
sudden changes could cause the tires to slide. You may
not realize the surface is slippery until your vehicle is
skidding. Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to make a
mirrored surface — and slow down when you have any
doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.
Operating Your All-Wheel-Drive
Vehicle Off Paved Roads
If your vehicle has 20-inch tire/wheel assemblies, you
should not drive off-road unless you are on a level, solid
surface. See Tires on page 5-56.
Many of the same design features that help make
your vehicle responsive on paved roads during poor
weather conditions — features like all-wheel
drive — help make it much better suited for off-road use
than a conventional passenger car. Its higher ground
clearance also helps your vehicle step over some
off-road obstacles. But your vehicle does not have
features like special underbody shielding and a transfer
case low gear range, things that are usually thought
necessary for extended or severe off-road service. This
guide is for operating your vehicle off paved roads.
Also, see Braking on page 4-5.
Off-road driving can be great fun. But it does have
some definite hazards. The greatest of these is
the terrain itself.
"Off-roading" means you have left the great North
American road system behind. Traffic lanes are not
marked. Curves are not banked. There are no
road signs. Surfaces can be slippery, rough, uphill or
downhill. In short, you have gone right back to nature.
