Manual Mode
Driver Shift Control (DSC)
Caution
Driving with the engine at a high
rpm without upshifting while using
Driver Shift Control (DSC), could
damage the vehicle. Always
upshift when necessary while
using DSC.

Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-12163021) -
2019 - CRC - 11/14/18
Driving and Operating 201
DSC allows you to shift an
automatic transmission similar to a
manual transmission. To use the
DSC feature:1. Move the shift lever to the left from D (Drive) into the side
gate marked with (+) and (−).
2. Move the shift lever forward to upshift or rearward to
downshift.
While using the DSC feature, the
vehicle will have firmer, quicker
shifting. You can use this for sport
driving or when climbing or descending hills, to stay in gear
longer, or to downshift for more
power or engine braking.
The transmission will only allow you
to shift into gears appropriate for the
vehicle speed and engine
revolutions per minute (rpm):
.
The transmission will not allow
shifting to the next higher gear if
the vehicle speed or engine rpm
is too low.
. The transmission will not allow
shifting to the next lower gear if
the vehicle speed or engine rpm
is too high.
While in the DSC mode, the
transmission will automatically
downshift when the vehicle comes
to a stop. This will allow for more
power during take-off.
When accelerating the vehicle from
a stop in snowy and icy conditions,
you may want to shift into second
gear. A higher gear allows the
vehicle to gain more traction on
slippery surfaces. Vehicles with a
turbocharged engine may also start
in third gear.
Drive Systems
All-Wheel Drive
If equipped, this feature transfers
torque to the rear wheels as
required. It is fully automatic, and
adjusts itself as needed for road
conditions.
All-Wheel Drive (AWD) performance
is automatically reduced when you
use the compact spare. To restore
full AWD performance, and prevent
excessive wear to the clutch in the
AWD system, replace the compact
spare tire with a full-size tire as
soon as possible. See Compact
Spare Tire 0318.
