− When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
− Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Autostick /Electronic Range Select (ERS) —
If Equipped
− By using the Autostick /Electronic Range Select (ERS)
mode and selecting a specific gear range, frequent
shifting can be avoided. The highest gear range should
be selected that allows for adequate performance. For
example, choose "4" if the desired speed can be
maintained. Choose "3" or "2" if needed to maintain
the desired speed.
− Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear range or vehicle
speed when road conditions and RPM level allows.
