GMC 2010 Canyon Crew Cab Owner's Manual page 134

3 (Third), 4 (Fourth) and 5 (Fifth): Shift into 3 (Third),
4 (Fourth) and 5 (Fifth) the same way you do for
2 (Second). Slowly let up on the clutch pedal as you
press the accelerator pedal.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press the
clutch pedal and the brake pedal, and shift to Neutral.
Neutral: Use this position when you start or idle the
engine.
R (Reverse): To back up, press the clutch pedal.
After the vehicle stops, shift into R (Reverse). Slowly let
up on the clutch pedal as you press the accelerator
pedal. If it is hard to shift, let the shift lever return
to Neutral and release the clutch pedal. Then press
the clutch again and shift into R (Reverse). Do not
attempt to shift into 5 (Fifth) prior to shifting into
R (Reverse). The transmission has a lock out feature
which prevents a 5 (Fifth) gear to R (Reverse) gear shift.
Notice: Shifting to R (Reverse) while the vehicle
is moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
Use R (Reverse), along with the parking brake, for
parking the vehicle.

Up-Shift Light
When this light comes on, you can shift to the next
higher gear if weather, road and traffic conditions permit.
For the best fuel economy, accelerate slowly and shift
when the light comes on.
While you accelerate, it is normal for the light to go on
and off if you quickly change the position of the
accelerator. Ignore the shift light when you downshift.
If the vehicle has four-wheel drive and has a manual
transmission, disregard the shift light when the transfer
case is in four-wheel low.
This light will show you
when to shift to the next
higher gear for best
fuel economy.
