Driving and Operating
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.
