194 STARTING AND OPERATING
Electronic Range Select (ERS)
• When using the ERS shift control, select the highest gear
that allows for adequate performance and avoids frequent
downshifts. For example, choose “5” if the desired speed
can be maintained. Choose “4” or “3” if needed to main-
tain the desired speed.
• To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as necessary to
avoid extended driving at high RPM. Return to a higher
gear range or vehicle speed when grade and road condi-
tions allow.
Speed Control — If Equipped
• Do not use on 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.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.
