Chevrolet 2007 Colorado Owner's Manual page 127

Here is how to operate your manual transmission:
FIRST (1): Press the clutch pedal and shift into
FIRST (1). Then, slowly let up on the clutch pedal
as you slowly press down on the accelerator pedal.
You can shift into FIRST (1) when you are going
less than 20 mph (30 km/h). If you have come to a
complete stop and it is hard to shift into FIRST (1),
put the shift lever in NEUTRAL and let up on the
clutch. Then press the clutch pedal back down and
shift into FIRST (1).
SECOND (2): Press the clutch pedal as you
let up on the accelerator pedal and shift into
SECOND (2). Then, slowly let up on the clutch
pedal as you press the accelerator pedal.
THIRD, FOURTH AND FIFTH (3, 4 and 5):
Shift into THIRD (3), FOURTH (4) and FIFTH (5)
the same way you do for SECOND (2). 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 your engine.
REVERSE (R): To back up, press the clutch pedal.
After the vehicle stops, shift into REVERSE (R).
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
REVERSE (R). Do not attempt to shift into the fifth
gear position prior to shifting into REVERSE (R).
Your transmission has a lock out feature which
prevents a fifth gear to reverse gear shift.
Notice: Shifting to REVERSE (R) while your
vehicle is moving forward could damage
the transmission. The repairs would not
be covered by your warranty. Shift to
REVERSE (R) only after your vehicle is
stopped.
Use REVERSE (R), along with the parking brake,
for parking your vehicle.
