Driving Down-Hill - GMC Hummer H3 2008 Owner's Handbook Manual

Starting and Operating Instructions
• If your vehicle does stall while
travelling up-hill, and you are
unable to back straight down,
do the following:
- Set the park brake.
- If your vehicle is fitted with an
automatic transmission, shift
into P (Park).
- Turn off the engine.
- Make sure that the transfer
case is in a drive gear and not
in N (Neutral). Otherwise, the
vehicle will be free to roll
even if the automatic trans-
mission is in P (Park) or the
manual transmission is in
gear.
- Exit the vehicle on the up-hill
side and get help. Stay clear
of the vehicle's roll-over path.
. . . 218
CAUTION
Shifting the transfer case to
N (Neutral) can cause your
vehicle to roll even if the
transmission is in P (Park) (or,
if you have the manual trans-
mission, even if you're in gear).
This is because the N (Neutral)
position on the transfer case
overrides the transmission.
The vehicle could move
suddenly. You or others may be
injured and objects could be
damaged.

DRIVING DOWN-HILL

When off-roading takes you down-
hill, you'll want to consider a
number of things:
• How steep is the down-hill
slope? Will I be able to main-
tain vehicle control?
• What's the surface like?
Smooth? Rough? Slippery?
Hard-packed dirt? Gravel?
• Are there hidden surface obsta-
cles? 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?
