select 1 (First) gear as the vehicle
stops. From a stop, the vehicle will
start from and hold 1 (First) gear
unless the manual paddle shifts are
used to shift into a different gear,
or D (Drive) is selected.
If the left ( ) minus paddle is held
down briefly, the transmission will
downshift to the lowest gear
possible for the vehicle speed. If the
paddle continues to be held as the
vehicle slows, downshifts will
continue to occur as vehicle speed
allows. This feature also works
while in Temporary Manual Paddle
Shift mode, but first press and
release the ( ) minus paddle to
enter Temporary Manual Paddle
Shift mode, then press and hold the
( ) minus paddle briefly.
The Manual Paddle Shift system will
not allow an upshift or a downshift if
the vehicle speed is too fast or too
slow, nor will it allow a start from
3 (Third) 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 instrument cluster
and HUD.
Manual Paddle Shift operation is
available for use with cruise control.
See Cruise Control 0 199.
The vehicle speeds required for
Manual Paddle Shift upshifts
depend on several vehicle inputs,
which will vary the allowed upshift
speed by a few km/h (mph).
For Vehicles with a 2.41:1 Axle
Ratio (RPO GXB)
Upshifts to 3 (Third) gear require
approximately 25 km/h (16 mph).
Upshifts to 4 (Fourth) gear
require approximately 37 km/h
(23 mph).
Upshifts to 5 (Fifth) gear require
approximately 48 km/h (30 mph).
Upshifts to 6 (Sixth) gear require
approximately 60 km/h (37 mph).
Driving and Operating
Upshifts to 7 (Seventh) gear
require approximately 74 km/h
(46 mph).
Upshifts to 8 (Eighth) gear
require approximately 95 km/h
(59 mph).
To prevent damage to the
powertrain, Manual Paddle
downshifts to a lower gear cannot
be done above certain speeds. The
maximum speed allowed for
downshifting of gears 1 (First)
through 7 (Seventh) are:
Into 7 (Seventh) gear over
365 km/h (227 mph).
Into 6 (Sixth) gear over 309 km/h
(192 mph).

183 km/h (114 mph).
Into 3 (Third) gear over
149 km/h (93 mph).
Into 2 (Second) gear over
100 km/h (62 mph).
