280 STARTING AND OPERATING
Automatic Transmission
The DRIVE range can be selected when towing. However,
if frequent shifting occurs while in DRIVE, use the Elec-
tronic Range Select (ERS) shift control to manually select a
lower gear range.
NOTE: Using a lower gear range while operating the
vehicle under heavy loading conditions, will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup. This action will also
provide better engine braking.
If you REGULARLY tow a trailer for more than 45 minutes
of continuous operation, then change the transmission
fluid and filter as specified for police, taxi, fleet, or
frequent trailer towing. Refer to the "Maintenance Plan"
for the proper maintenance intervals.
Electronic Range Select (ERS)
• When using the ERS shift control, select the highest gear
that allows for adequate performance and avoids fre-
quent downshifts. For example, choose "4" if the desired
speed can be maintained. Choose "3" or "2" if needed to
maintain 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
conditions 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 overheat-
ing, 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.
