Automatic Transmission Features
Electronic Range Select (ERS) Mode
The Electronic Range Select mode allows
the driver to manually select the range of
gear positions. This feature can be used
to limit the top gear while towing or to
downshift when driving on a downhill
grade to provide engine braking. ERS
is not designed to provide sportier
performance or to be used to shift
gears similar to a manual transmission.
• Move the shift lever to the Manual (M)
position.
• Press the +/–button (B) on the shift
lever to increase/decrease the gear
range available. All gears below the
selected gear will be available to use.
If vehicle speed is too high or too low for
the requested gear, the shift will not occur.
See Driving and Operating in your Owner Manual.

may be more noticeable and more noise
and vibration at idle may be experienced.

lever to turn the eco mode on or off.
