GMC 2007 Canyon - Manual (Page 265)

Q:
Are there some things I should not do
when driving down a hill?
A:
Yes! These are important because if you
ignore them you could lose control and
have a serious accident.
• When driving downhill, avoid turns that take
you across the incline of the hill. A hill that
is not too steep to drive down may be
too steep to drive across. You could roll over
if you do not drive straight down.
• Never go downhill with the transmission in
NEUTRAL (N), or with the clutch pedal pressed
down with a manual transmission. This is called
“free-wheeling.” The brakes will have to do all
the work and could overheat and fade.
Q:
Am I likely to stall when going downhill?
A:
It is much more likely to happen going uphill. But
if it happens going downhill, here is what to do.
1. Stop your vehicle by applying the regular
brakes. Apply the parking brake.
2. Shift to PARK (P), or to NEUTRAL with the
manual transmission, and, while still braking,
restart the engine.
3. Shift back to a low gear, release the parking
brake, and drive straight down.
4. If the engine will not start, get out and
get help.
Driving Across an Incline
Sooner or later, an off-road trail will probably go
across the incline of a hill. If this happens,
you have to decide whether to try to drive across
the incline. Here are some things to consider:
• A hill that can be driven straight up or
down may be too steep to drive across. When
you go straight up or down a hill, the length
of the wheel base — the distance from
the front wheels to the rear wheels — reduces
the likelihood the vehicle will tumble end
over end. But when you drive across
an incline, the much more narrow track
width — the distance between the left and
right wheels — may not prevent the vehicle
from tilting and rolling over. Also, driving
across an incline puts more weight on
the downhill wheels. This could cause a
downhill slide or a rollover.
