Manual Mode
Electronic Range Select (ERS)Caution
Driving 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

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).
