Driving Downhill - GMC 2001 Sierra 1500 Pickup Owner's 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) (or the manual transmission in
FIRST (1)) 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. Do not shift the transfer
case to NEUTRAL when you leave the vehicle.
Leave it in some gear.
CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the transmission
is in PARK (P) (or, if you have the manual
transmission, even if you're in gear). This is
because the NEUTRAL position on the
transfer case overrides the transmission.
4-26
CAUTION: (Continued)
CAUTION: (Continued)
You or someone else could be injured. If you
are going to leave your vehicle, set the parking
brake and shift the transmission to PARK (P)
(or, put your manual transmission in FIRST (1)).
But do not shift the transfer case to NEUTRAL.
Leave the transfer case in the 2 Wheel High,
4 High or 4 Low position.

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?
