Electronic Range Select (ERS)
●
When using the ERS shift control, select the highest
gear that allows for adequate performance and
avoids frequent 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.
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 (ERS)
shift control) on more severe grades.
Cruise Control — If Equipped
●
Do not use on hilly terrain or with heavy loads.
●
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
disengage until you can get back to cruising speed.
●
Use Cruise Control in flat terrain and with light loads
to maximize fuel efficiency.
Air Suspension System
To aid in attaching/detaching the trailer from the
vehicle, the air suspension system can be used
page 136
. Selecting Tow/Haul or connecting a trailer
with an Integrated Trailer Brake Module (ITBM) will
disable Automatic Aero mode to avoid height changes
while towing and shifting loads or tongue weights.
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
recommended that the owner/installer obtain and
follow the recommendations contained within the
current Body Builder’s 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 overloading 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.
CAUTION!
The “Lamp Out” indicator could illuminate if exterior
lamps are not properly installed.
