Driving Downhill - GMC Yukon Denali 2003 Owner's Manual

Driving Downhill

When off-roading takes you downhill, you'll want to
consider a number of things:
•
How steep is the downhill? Will I be able to maintain
vehicle control?
•
What's the surface like? Smooth? Rough? Slippery?
Hard-packed dirt? Gravel?
•
Are there hidden surface obstacles? Ruts? Logs?
Boulders?
•
What's at the bottom of the hill? Is there a
hidden creek bank or even a river bottom with
large rocks?
If you decide you can go down a hill safely, then try to
keep your vehicle headed straight down, and use a
low gear. This way, engine drag can help your brakes
and they won't have to do all the work. Descend slowly,
keeping your vehicle under control at all times.
{
CAUTION:
Heavy braking when going down a hill can
cause your brakes to overheat and fade. This
could cause loss of control and a serious
accident. Apply the brakes lightly when
descending a hill and use a low gear to keep
vehicle speed under control.
Q:
Are there some things I should not do when
driving down a hill?
A:
Yes! These are important because if you ignore
them you could lose control and have a serious
accident.
•
When driving downhill, avoid turns that take you
across the incline of the hill. A hill that's not too
steep to drive down may be too steep to drive
across. You could roll over if you don't drive
straight down.
•
Never go downhill with the transmission in
NEUTRAL (N). This is called "free-wheeling." Your
brakes will have to do all the work and could
overheat and fade.
