Chevrolet 2003 Blazer Owner's Manual page 224

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. 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 a drive gear.
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?
0
What's the surface like? Smooth? Rough? Slippery?
Hard-packed dirt? Gravel?
Are there hidden surface obstacles? Ruts? Logs?
0
What's at the bottom of the hill? Is there a hidden
Boulders?
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 y lr vehicle under control at all times.
Heavy ,,,ki n g 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.
