Performance Shifting with TAP-Shift™
The other gearshift positions available are
PARK (P), REVERSE (R), NEUTRAL (N) and
AUTOMATIC OVERDRIVE (D), and operate
as explained earlier in this section.
2-28
If the vehicle is equipped
with the 3800 V6
Supercharged engine,
it may have a console
gearshift with a
MANUAL (M) position.
While in the MANUAL (M) position, the paddles, located
on the steering wheel, can be used to up-shift or
down-shift the transaxle, under certain circumstances.
To fully use the system, select MANUAL (M) while
stopped, with the engine running. The vehicle will begin
moving in first gear upon acceleration. For better
control in icy or slippery conditions, the vehicle may
start out in second gear, rather than first gear.
While in the MANUAL (M)
mode, push either paddle
once to up-shift to the
next gear. Pull either
paddle once to down-shift
to the next gear.
