Pontiac 2005 Grand Prix - Manual (Page 93)

The up-shift indicator light
on the instrument panel
cluster, or the up-shift
symbol on the Head-Up
Display (HUD), if equipped,
is given as a prompt to
use the TAP-Shift ™
paddle.
The up-shift indicator light will only appear in the
instrument panel cluster if the HUD is off or if the
vehicle does not have HUD.
This prompt to up-shift, as needed, will be given
throughout acceleration. If up-shifting does not occur
when prompted, the vehicle speed will be limited
to protect the engine.
Press the accelerator while driving in the highest
gear (fourth gear) which is between 20 and 50 mph to
make the transaxle automatically down-shift. As
you’re speed gets closer to 50 mph, more effort will
be required to press the acclerator. At 50 mph, even
with the accelerator fully depressed, the transaxle
will always remain in the 4th gear. The transaxle will
also automatically down-shift as the vehicle decelerates
and comes to a stop.
When a paddle is pushed or pulled a chime will sound
when the vehicle cannot respond to a transaxle gear
change. The system will not allow either an up-shift or a
down-shift if the vehicle speed is too fast or too slow,
nor will it allow a start from THIRD (3) or higher gear.
The MANUAL (M) gear can also be selected while
the vehicle is already moving. The current transaxle
position will continue to be displayed on the Driver
Information Center (DIC) and HUD, if equipped.
