STARTING AND OPERATING225
TOWING TIPS
Before towing, 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 performance and extend transmission life
by reducing excessive shifting and heat build up.
This action will also provide better engine braking.
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
Úpage 165. 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 recom -
mended 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 infor -
mation. 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.

IN CASE OF EMERGENCY375
NOTE:
Your vehicle may be transmitting data as autho -
rized by the subscriber.
Never place anything on or near the vehicle’s
LTE (voice/data) or 4G (data) and GPS
antennas. You could prevent LTE (voice/data) or
4G (data) and GPS signal reception, which can
prevent your vehicle from placing an emergency
call. An operable LTE (voice/data) or 4G (data)
network connection and a GPS signal is
required for the SOS Call system to function
properly.
NOTE:Changes or modifications not expressly approved
by the party responsible for compliance could void
the user's authority to operate the equipment.
Automatic SOS — If Equipped
Automatic SOS is a hands-free safety service that
can immediately connect you with help in the event
that your vehicle’s airbags deploy. Please refer to
your provided radio supplement for complete
information.
JACKING AND TIRE CHANGING NOTE:If your vehicle is equipped with an air suspension
system, there is a feature which allows the auto -
matic leveling to be disabled to assist with
changing a tire. This feature can be activated
through the Uconnect system Ú page 253.
PREPARATIONS FOR JACKING
NOTE:
If your vehicle is equipped with Air Suspension, you
will need to enable Tire Jack Mode in the Uconnect
system Úpage 165 before changing the tire.
1. Park on a firm, level surface. Avoid ice or slippery areas.
2. Turn on the Hazard Warning Flashers.
3. Apply the parking brake.
4. Shift the transmission into Park (P).
5. Turn the ignition OFF.
WARNING!
Do not attempt to change a tire on the side of
the vehicle close to moving traffic. Pull far
enough off the road to avoid the danger of
being hit when operating the jack or changing
the wheel.
Being under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on
you. You could be crushed. Never put any part
of your body under a vehicle that is on a jack.
If you need to get under a raised vehicle, take
it to a service center where it can be raised on
a lift.
Never start or run the engine while the vehicle
is on a jack.
The jack is designed to be used as a tool for
changing tires only. The jack should not be
used to lift the vehicle for service purposes.
The vehicle should be jacked on a firm level
surface only. Avoid ice or slippery areas.
WARNING!
Do not attempt to change a tire on the side of
the vehicle close to moving traffic. Pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel.
