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)
on page 3-44 and DIC Operation
and Displays (With DIC Buttons) on
page 3-45 or DIC Operation and
Displays (Without DIC Buttons) on
page 3-51 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 on page 2-26 for
more information.
Tow/Haul Mode
_
(Tow/Haul): The vehicle may
have a Tow/Haul mode.
The button is located on the
instrument panel under the climate
controls.
Push the button to activate the
system. Push it again to deactivate
the system. You can use this
feature to assist when towing or
hauling a heavy load.
