2 (Second) gear unless the manual
paddle shifts are used to shift into a
different gear, or D (Drive) is
selected. The driver can select
1 (First) gear for maximum
acceleration from a stop.
The Manual Paddle Shift system will
not allow either an upshift or a
downshift if the vehicle speed is too
fast or too slow, nor will it allow a
start from 4 (Fourth) or higher gear.
If upshifting does not occur when
needed, vehicle speed will be
limited to protect the engine.
When a requested shift is denied
due to the speed restrictions shown,
a DIC message will be displayed,
and the current gear remains
displayed in the cluster and HUD.
Manual Paddle Shift operation is
available for use with cruise control.

The vehicle speeds required for
Manual Paddle Shift upshifts
depend on several vehicle inputs,
which will vary the allowed up-shift
speed by a few km/h (mph).
For vehicles with a 2.56:1 Axle
Ratio (RPO GM8 without Z51)
Upshifts to 4 (Fourth) gear
require approximately 35 km/h
(22 mph).
Upshifts to 5 (Fifth) gear require
approximately 45 km/h (28 mph).
Upshifts to 6 (Sixth) gear require
approximately 65 km/h (41 mph).
