Electronic Speed Control – If Equipped
−
Do not use in hilly terrain or with heavy loads.
−
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威 – If Equipped
−
By using the AutoStick威 mode and selecting a specific
gear range, frequent shifting can be avoided. Select the
highest gear range that allows for adequate perfor-
mance and avoids frequent downshifts.
−
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.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
−
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
