STARTING AND OPERATING 185
Automatic Transmission
The DRIVE range can be selected when towing.
However, if frequent shifting occurs while in
DRIVE, use the AutoStick shift control to
manually select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
un
der heavy loading conditions will improve
performance and extend transmission life by
reducing excessive shifting and heat build up.
This action will also provide better engine
braking.
If you REGULARLY tow a trailer for more than
45
minutes of continuous operation, then
ch
ange the transmission fluid and filter as
specified for “police, taxi, fleet, or frequent
trailer towing”. Refer to the “Scheduled
Servicing” in “Servicing And Maintenance” for
the proper maintenance intervals.
NOTE:
Check the automatic transmission fluid level
be
fore towing. If you notice fluid leakage or
transmission malfunction, see an authorized
dealer immediately for assistance.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Speed Control, if you experi-
ence speed drops greater than 10 mph
(1
6 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
When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent down-
shifts. For example, choose “4” if the desired
sp
eed 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 or vehicle speed when grade and
road conditions allow.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the
tr
ansmission in NEUTRAL, but do not increase
engine idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.
