Driving Downhill - GMC 2005 Canyon Owner's Manual

Here are some things you must not do if you stall, or
are about to stall, when going up a hill.
•
Never attempt to prevent a stall by shifting into
NEUTRAL (N) (or pressing the clutch, if you have a
manual transmission) to rev-up the engine and
regain forward momentum. This will not work. Your
vehicle will roll backwards very quickly and you
could go out of control.
Instead, apply the regular brake to stop the vehicle.
Then apply the parking brake. Shift to
REVERSE (R), release the parking brake, and
slowly back straight down.
•
Never attempt to turn around if you are about to
stall when going up a hill. If the hill is steep
enough to stall your vehicle, it is steep enough to
cause you to roll over if you turn around. If you
cannot make it up the hill, you must back straight
down the hill.
Q:
Suppose, after stalling, I try to back down the hill
and decide I just cannot 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.

Driving Downhill

When off-roading takes you downhill, you will want to
consider a number of things:
•
How steep is the downhill? Will I be able to maintain
vehicle control?
•
What is the surface like? Smooth? Rough?
Slippery? Hard-packed dirt? Gravel?
•
Are there hidden surface obstacles? Ruts? Logs?
Boulders?
•
What is 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 will not have to do all the work. Descend
slowly, keeping your vehicle under control at all times.
