270 STARTING AND OPERATING
NOTE:
Using TOW mode, or selecting a lower gear
(using the AutoStick shift control) while oper-
ating the vehicle under heavy loading condi-
tions, will improve performance and extend
transmission life by reducing excessive shifting
and heat buildup. This action will also provide
better engine braking.
TOW Mode
To reduce the potential for automatic
transmission overheating, select TOW mode
when driving in hilly areas, or select a lower gear
(using the AutoStick shift paddles) on more
severe grades.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent down-
shifts. For example, choose “5” if the desired
speed can be maintained. Choose “4” or “3”
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.
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
(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
overheating, 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.
SNOW PLOW
Snow plows, winches, and other aftermarket
equipment should not be added to the front end
of your vehicle. The airbag crash sensors may
be affected by the change in the front end
structure. The airbags could deploy
unexpectedly or could fail to deploy during a
collision.
WARNING!
Do not add a snow plow, winches, or any
other aftermarket equipment to the front of
your vehicle. This could adversely affect the
functioning of the airbag system and you
could be injured.
