Cadillac 2006 CTS Owner's Manual page 107

THIRD (3), FOURTH (4), FIFTH (5) and SIXTH (6):
Shift into THIRD (3), FOURTH (4), FIFTH (5) and
SIXTH (6) 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. Your shift lever is in NEUTRAL when it is
centered in the shift pattern, not in any gear.
REVERSE (R): To back up, press down the clutch
pedal, completely stop the vehicle, and shift into
REVERSE (R). Let up on the clutch pedal slowly while
pressing the accelerator pedal.
For the CTS, pull the shift lever quickly to the left and
then forward into gear.
For the CTS-V, your six-speed manual transmission has
a safety feature that prevents you from shifting into
REVERSE (R) while the vehicle is driven at speeds
greater than 3 mph (5 km/h). You will be locked out if
you try to shift into REVERSE (R) while your vehicle
is moving faster than 3 mph (5 km/h). If you have turned
your ignition off and wish to park your vehicle in
REVERSE (R), you will have to overcome the lockout
mechanism by moving the shift lever quickly to the right,
and immediately forward into gear using more force
than a normal shift.
