Chevrolet 2007 Colorado Owner's Manual page 407

Front Position
If the flat tire is on the front of the vehicle,
position the jack to the rear of the front tire
in the pocket off of the frame.
Rear Position
If the flat tire is on the rear, position the
jack under the rear axle and get as close
as possible to the shock absorber.
4. Make sure the jack head is positioned so that
the rear axle is resting securely between the
grooves that are on the jack head.
5. Turn the wheel wrench clockwise to raise the
vehicle. Raise the vehicle far enough off the
ground so there is enough room for the spare
tire to fit under the wheel well.
