354 STARTING AND OPERATING
If you regularly tow a trailer for more than 45 minutes of
continuous operation, then change the automatic transmis-
sion fluid and filter(s) as specified for "police, taxi, fleet, or
frequent trailer towing." Refer to the “Maintenance Plan” for
the proper maintenance intervals.
NOTE:
Check the automatic transmission fluid level before towing
(Six-speed automatic only).
Tow/Haul Mode
To reduce potential for automatic transmission overheating,
activate TOW/HAUL mode when driving in hilly areas, or
select a lower gear range (using the Electronic Range Select
(ERS) shift control) on more severe grades.
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.
Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air Suspen-
sion System” in “Starting And Operating” for further infor-
mation.
NOTE:
The vehicle must remain in the engine running position
while attaching a trailer for proper leveling of the air suspen-
sion system.
