Electronic Speed Control — If Equipped
•Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience 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 over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed. Air Conditioning
Turn off temporarily.
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
1500 Models Only
NOTE: Do not use this model vehicle for snowplow
applications.

STARTING AND OPERATING 601
Page 609 of 790

NOTE:Vehicles equipped with air suspension must be
lowered to the “Entry/Exit” (lowest) level, and have
automatic leveling disabled, before tying them down
(from the body) on a trailer or flatbed truck. Refer to “Air
Suspension – If Equipped” for more information. If the
vehicle cannot be lowered to the “Entry/Exit” level (for
example, engine will not run), tie-downs must be fas-
tened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.
Recreational Towing — Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is
allowed ONLYif the rear wheels are OFFthe ground.
This may be accomplished using a tow dolly or vehicle
trailer. If using a tow dolly, follow this procedure: 1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place automatic trans- mission in PARK, manual transmission in gear (not in
NEUTRAL).
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer’s instructions.
5. Turn the ignition switch to the OFF position and remove the Key Fob.
6. Install a suitable clamping device, designed for tow- ing, to secure the front wheels in the straight position.

JACKING AND TIRE CHANGING
Jacking And Tire Changing 1500 Series Trucks
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.
(Continued)
WARNING! (Continued)
•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.
NOTE: To assist with changing a spare tire, the air
suspension system has a feature which allows the auto-
matic leveling to be disabled. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
Jack Location
The jack and jack tools are stored under the front
passenger seat.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial wrecker service. If the trans-
mission and drivetrain are operable, disabled vehicles
may also be towed as described under “Recreational
Towing” in the “Starting and Operating” section.NOTE:
Vehicles equipped with air suspension must be
placed in Transport mode, before tying them down (from
the body) on a trailer or flatbed truck. Refer to Air
Suspension inStarting and Operating for more infor-
mation. If the vehicle cannot be placed in Transport mode
(for example, engine will not run), tie-downs must be
fastened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.
