Winter Driving - Chevrolet Low Cab Forward 6.7L 2022 Owner's Manual

118 Driving and Operating
1. Red Zone
Drive at a speed that does not cause the
tachometer needle to enter the red zone.
Uphill
Shift down well ahead of time in order to
avoid a heavy load to the engine.
Downhill
Be careful not to drive too fast on a
downhill road.
Use the same gear(s) that you used to
drive up the hill. Also, use the exhaust
brake in order to avoid going too fast.
Do not let the engine overrun.
When going down on a steep slope, avoid
driving the vehicle backward as much as
possible. Drive it forward slowly on the
down slope.
Compared with forward movement, the
braking distance of backward movement
is longer, and the steering response of
that is worse.
If you must drive the vehicle backward,
drive it very carefully and gradually by
moving and stopping repeatedly in order
to stop it any time.
Engine Brake : Engine brake is the braking
effect that occurs when you release the
accelerator pedal while driving. The lower
the gear, the stronger the engine brake.
Exhaust Brake : The exhaust brake is a
system that closes the exhaust pipe and
uses the force of the exhaust emissions to
enhance the effectiveness of engine brake.
Overrunning : An engine overrun is an
engine-speed increase that causes the
tachometer needle to enter the red zone.
It is dangerous because it can cause engine
failure.
