Driving Downhill - GMC SIERRA DENALI 2002 Manual

Q:
Suppose, after stalling, I try to back down the
hill and decide I just can't do it. What should
I do?
A:
Set the parking brake, put your transmission in
PARK (P) and turn off the engine. Leave the
vehicle and go get some help. Exit on the uphill
side and stay clear of the path the vehicle would
take if it rolled downhill.

Driving Downhill

-
When off roading takes you downhill, you'll want to
consider a number of things:
D
How steep is the downhill? Will I be able to maintain
vehicle control?
D
What's the surface like? Smooth? Rough? Slippery?
-
Hard packed dirt? Gravel?
D
Are there hidden surface obstacles? Ruts?
Logs? Boulders?
D
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.
