and performance. Use the brake to
hold the vehicle on a hill. Do not use
the accelerator pedal.
L :
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. See
Operating Modes :
The
transmission may operate in a lower
gear than normal to improve vehicle
performance. The engine speed
may be higher and there may be an
increase in noise during the
following conditions:
.
When climbing a grade.

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 downhill or towing a trailer.
The vehicle has an electronic shift
position indicator within the
instrument cluster. When using the
ERS mode a number will display
next to the L, indicating the highest
gear available for the range
selected.
To use this feature:
1. Move the shift lever to
L (Manual Mode).
2. Press + (Plus) or
−
(Minus) on
the shift lever to increase or
decrease the gear range
available.
When you shift from D (Drive) to
L (Manual Mode), 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)
or
Information Center (DIC) (Uplevel)
. 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).
