GMC YUKON XL 2003 - Driving Downhill

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. Do not shift the transfer
case
to NEUTRAL when you leave the vehicle.
Leave it in some gear.
arlifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). This is because
the NEUTRAL position on the transfer case
overrides the transmission. 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). 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:
How steep is the downhill? Will I be able to maintain
What’s the surface like? Smooth? Rough? Slippery:/
Are there hidden surface obstacles? Ruts? Logs?
What’s at the bottom of the hill? Is there a
vehicle control?
Hard-packed dirt? Gravel?
Boulders?
hidden creek bank or even a river bottom with
large rocks?
