Manual Mode Electronic Range Select (ERS)
CautionDriving with the engine at a high
rpm without upshifting while using
Manual Mode, could damage the
vehicle. Always upshift when
necessary while using
Manual Mode.
Electronic Range Select (ERS),
or Manual Mode, allows for the
selection of the range of gear positions. Use this mode when
driving downhill or towing a trailer to
limit the top gear and vehicle speed.
The shift position indicator within the
Driver Information Center (DIC) will
display a number next to the L
indicating the highest available gear.
To enter Electronic Range Select or
Manual Mode:
1. With the vehicle in D (Drive),
pull back on the shift lever to
activate L (Low). The L in the
shift pattern will illuminate in
red, and the D will switch to
white.
2. Tap the left steering wheel
control to reduce the highest
gear available, or the right
control to increase the highest
gear available.
3. To exit, pull back on the shift
lever a second time. The D in
the shift pattern will illuminate
in red, and the L will switch to
white.
When shifting to L (Low), the
transmission will shift to a preset
lower gear range. For this preset range, the highest gear available
will be displayed next to the L in the
DIC. All gears below that number
are available to use. For example,
when 4 (Fourth) is shown next to
the L, 1 (First) through 4 (Fourth)
gears are shifted automatically. To
shift to 5 (Fifth) gear, tap the right
steering wheel control or shift into D
(Drive).
L (Low) will prevent shifting to a
lower gear range if the engine
speed is too high. If the vehicle
speed is not reduced within the time
allowed, the lower gear range shift
will not be completed. Slow the
vehicle, then tap the left steering
wheel control to the desired lower
gear range.
Cruise control can be used while
in ERS.
