WARNING!
If the stabilizer/sway bar will not return to On-Road
mode, vehicle stability is greatly reduced. Do not
attempt to drive the vehicle over 18 mph (29 km/h).
Driving faster than 18 mph (29 km/h) may cause loss
of control of the vehicle, which could result in
serious injury or death. Contact your local service
center for assistance.

Off-Road Driving Tips And Vehicle Characteristics
Your vehicle has excellent on and off-road capabilities.
These off-road capabilities will allow you to explore
those wilderness trails where few travel, providing a
source of exciting and satisfying recreation. Before you
venture out, you should contact your local governmentalagency to determine the designated off-road vehicle
(ORV) trails or recreation areas. You should always tread
lightly and only use established roads, trails or ORV
recreational areas. The National Forest Service, Bureau of
Land Management or local Department of Natural Re-
sources are a wealth of information and usually have
maps with marked trails.
Skid Plates And Underbody Protection
Steel skid plates protect the major driveline components
of the truck including the fuel tank, transfer case and
steering damper. In addition, this vehicle is equipped
with boxed cross members and fore/aft rails. This addi-
tional protection allows the vehicle to be utilized in
severe off-road situations that would be considered im-
passable by a normal truck.
Ramp Travel Index (RTI)
The ramp travel index is the distance, in inches, that you
can drive your vehicle with one wheel on a 20-degree

WARNING!
Winch cables are under high tension when in use and
can become a projectile if they fail. Never stand over
or straddle the winch cable. Never jerk or overload
the winch cable. Never stand in front of the vehicle
while winching. Failure to follow these instructions
can result in serious or fatal injury.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you
can get any problems taken care of right away and have
your vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage. •
Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
• After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.

WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.

If the Steering icon is flashing, it indicates that the vehicle
needs to be taken to the dealer for service. It is likely the
vehicle has lost power steering assistance.
If the Steering icon is displayed and the “POWER STEER-
ING SYSTEM OVER TEMP” message is displayed on the
EVIC screen, they indicate that extreme steering maneuvers
may have occurred which caused an over temperature
condition in the power steering system. Once driving
conditions are safe, pull over and let the vehicle idle for a
few moments until the icon and message turn off. Refer to
“Electronic Vehicle Information (EVIC)” in “Understanding
Your Instrument Panel” for further information.
If the Steering icon is displayed and the “SERVICE
POWER STEERING – ASSIST OFF” message is displayed
the EVIC screen, they indicate the vehicle needs to be
taken to the dealer for service. Refer to “Electronic
Vehicle Information (EVIC)” in “Understanding Your
Instrument Panel” for further information.NOTE:
•
Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle.
Under these conditions there will be a substantial
increase in steering effort, especially at low speeds and
during parking maneuvers.
• If the condition persists, see your authorized dealer for
service.
POWER STEERING — 2500/3500 MODELS
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
510 STARTING AND OPERATING
Page 513 of 790

If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
Power Steering Fluid Check — 2500/3500 Models
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an autho-
rized dealer.5

WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving unattended
children in a vehicle is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured.
• Do not leave the Key Fob in or near the vehicle, or
in a location accessible to children, and do not
leave a vehicle equipped with Keyless Enter-N-
Go™ in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move
the vehicle.
(Continued)
WARNING! (Continued)
•Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to brake
failure and a collision.
• Always fully apply the parking brake when leav-
ing your vehicle or it may roll and cause damage or
injury. Also, be certain to leave the transmission in
PARK. Failure to do so may cause the vehicle to roll
and cause damage or injury.
CAUTION!
If the Brake System Warning Light remains on with
the parking brake released, a brake system malfunc-
tion is indicated. Have the brake system serviced by
an authorized dealer immediately.

further information. When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will flash, the
engine power may be reduced and you may feel the
brakes being applied to individual wheels to attempt to
stop the trailer from swaying. TSC is disabled when the
ESC system is in the “Partial Off” or “Full Off” modes.
TSC is only active in the default “ESC On” mode. TSC
can be disabled by pressing the “ESC Off” switch and
entering “ESC Partial Off” mode. It is not active in the
“ESC Partial Off” or “ESC Off” modes. Refer to the ESC
portion of this section for an explanation of the different
ESC operating modes.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
