Driving Downhill - Chevrolet 2009 TrailBlazer Owner's Manual

Things not to do if the vehicle stalls, or is about to stall,
when going up a hill:
•
Never attempt to prevent a stall by shifting into
N (Neutral) to rev-up the engine and regain forward
momentum. This will not work. The vehicle can roll
backward very quickly and could go out of control.
•
Never try to turn around if about to stall when going
up a hill. If the hill is steep enough to stall the vehicle,
it is steep enough to cause it to roll over. If you
cannot make it up the hill, back straight down the hill.
If, after stalling, you try to back down the hill and decide
you just cannot do it, set the parking brake, put your
transmission in P (Park), 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.
4-22
CAUTION:
{
Shifting the transfer case to Neutral can cause your
vehicle to roll even if the transmission is in P (Park).
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 P (Park). But do not shift the
transfer case to Neutral.

Driving Downhill

When off-roading takes you downhill, consider:
•
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?
