TOWING TIPS
Before setting out on a trip, practice turning, stopping,
and backing up the trailer in an area located away from
heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, select TOW/HAUL
mode or select a lower gear range (using the Electronic
Range Select [ERS] shift control).
NOTE:
Using TOW/HAUL mode or selecting a lower gear range
(using the ERS shift control) while operating the vehicle
under heavy loading conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build-up. This action will also pro-
vide better engine braking.
Tow/Haul Mode
To reduce potential for automatic transmission over-
heating, 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), disen-
gage 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 transmis-
sion 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 Suspension System” in “Starting And Operating”
for further information.
NOTE:
The vehicle must remain in the engine running position
while attaching a trailer for proper leveling of the air
suspension system.
SNOWPLOW
Snowplow Prep Packages are available as a factory
installed option. These packages include components
necessary to equip your vehicle with a snowplow.
NOTE:
Before installation of a snowplow it is highly recom-
mended that the owner/installer obtain and follow the
recommendations contained within the current Body
Builders Guide. See an authorized dealer, installer or
snowplow manufacturer for this information. There are
unique electrical systems that must be connected to
properly ensure operator safety and prevent overload-
ing vehicle systems.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision.
Do not expect that the airbag will perform as
described earlier in this manual.
