GMC Acadia/Acadia Denali Owner Manual - 2011
Driving and Operating 9-27
If the vehicle is stopped on a hill,
with your foot off the brake pedal,
the vehicle may roll. This is normal
and is due to the torque converter
designed to improve fuel economy
and performance. Use the brake to
hold the vehicle on a hill. Do not use
the accelerator pedal.
L (Low): This position gives
you access to gear ranges. This
provides more engine braking but
lower fuel economy than D (Drive).
You can use it on very steep hills,
or in deep snow or mud.
Manual Mode
Electronic Range Select
(ERS) Mode
ERS mode allows you to choose the
top-gear limit of the transmission
and the vehicle's speed while
driving down hill or towing a trailer.
The vehicle has an electronic
shift position indicator within
the instrument panel cluster.
When using the ERS Mode a
number will display next to the L,
indicating the current gear that has
been selected.
To use this feature:
1. Move the shift lever to L (Low).
2. Press the plus/minus button
located on the shift lever, to
increase or decrease the gear
range available.
When you shift from D (Drive) to
L (Low), the transmission will shift to
a pre-determined lower gear range.
The highest gear available for this
pre-determined range is displayed
next to the L in the DIC. See Driver
Information Center (DIC) (With DIC
Buttons)
on page 525
or Driver
Information Center (DIC) (Without
DIC Buttons)
on page 529
for
more information. The number
displayed in the DIC is the highest
gear that the transmission will be
allowed to operate in. This means
that all gears below that number
are available. For example, when
4 (Fourth) is shown next to the L,
1 (First) through 4 (Fourth) gears are
automatically shifted by the vehicle.
The transmission will not shift into
5 (Fifth) until the + (Plus) button is
used or you shift back into D (Drive).
While in L (Low), the transmission
will prevent shifting to a lower gear
range if the engine speed is too
high. You have a brief period of
time to slow the vehicle. If vehicle
speed is not reduced within the time
allowed, the lower gear range shift
will not be completed. You must
further slow the vehicle, then press
the (Minus) button to the desired
lower gear range.
Automatic Engine Grade braking
is not available when the ERS is
active. It is available in D (Drive) for
both normal and Tow/Haul mode.
While using the ERS, cruise control
and the tow/haul mode can be used.
See Tow/Haul Mode following.
