Driving and Operating 9-25
Manual Mode
Electronic Range Select
(ERS) Mode
ERS mode allows you to
choose the top-gear limit of the
transmission, which can help
control 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 current
range that has been selected.
To use this feature:
1. Move the shift lever to L (Low).
2. Press the + (Plus) or − (Minus)
button located on the left side of
the steering wheel, 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. The
number displayed in the DIC is the
highest gear that the transmission
will be allowed to operate in. 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.
