High-Pressure Monotube Shocks/New Front and
Rear Springs
The new variable-rate shocks and revised springs help to
create a suitable on-road ride without compromising
off-road competency. The shocks are designed to provide
improved stability, durability, and suspension articula-
tion.
Off-Road Tires
These tires are specifically designed for extreme off-road
use, while also maintaining quite on-road operation.The
tires utilize long-life compounds for increased durability,
and a deep-groove tread for extra traction. The LT285/
70R17D used provides a large contact patch for better
traction, two full-width steel belts for improved strength,
as well as a reinforced sidewall to help protect against
bruising and shredding.
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 the Power Wagon is
equipped with boxed cross membes and fore/aft rails.
This additional protection allows the vehicle to be uti-
lized in severe off-road situations that would be consid-
ered impassable by a normal truck.
Wheel Flares
Not just for looks, the wheel flares on the Power Wagon
were designed to help cover its new larger off-road tires.
The larger flares also help to reduce the amount of debris
that can be flung up by the more aggressive tread pattern
on the tires.
82 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
Wheels
Stylish forged aluminum 17wheels give the Power
Wagon a powerful stance. Forging a wheel from alumi-
num produces a stronger, lighter weight wheel than
machining or casting the wheel out of the same material.
Standard package features:
•
Fuel Tank Skid Plate - protects the fuel tank from
impingement damage.
•Transfer Case Skid Plate and Tubing - protects the
transfer case and exhaust catalyst from impingement
damage.
•Heavy Duty Cross Members - protects the under
carriage and supports the under body protection skid
plates.
•Fore/Aft rails - which connect the cross member for
additional support and prevent the truck from getting
hung up on large rocks between the cross members.
•Steering Dampener Skid Plate - protects the steering
dampener from impingement damage.
•Electronically Locking Front And Rear Axle Differen-
tials With 4:56 Gears - improves mobility and articu-
lation by locking the differentials.
•Electronically Disconnecting Stabilizer/Sway Bar - im-
proves mobility and articulation by disconnecting the
Stabilizer/Sway Bar.
•160 Amp Alternator - supplies increased electrical
power for the winch and other off-road accessories.
•Heavy Duty Battery - supplies increased electrical
power for the winch and other off-road accessories.
•Heavy Duty Cooling Fan - provides enhanced engine
and transmission cooling under vigorous off-road
conditions.

WARNING!
Always wear your seat belt and firmly tie down
cargo. Unsecured cargo can become projectiles in an
off-road situation.
When To Use Low Range
When driving off-road, shift into 4L (Low range) for
additional traction or to improve handling and control on
slippery or difficult terrain. Due to the lower gearing, low
range will allow the engine to operate in a higher power
range. This will allow you to idle over obstacles and
down hills, with improved control and less effort. Also,
use 4L (Low range) in rain, ice, snow, mud, sand, to get
heavy loads rolling, improve traction, or whenever 4H
(High range) traction will not do the job.
Driving in Snow, Mud and Sand
There is a drastic reduction in traction when driving in
snow, mud or sand. The vehicle will be less responsive to
steering, acceleration and braking inputs. Therefore you
should accelerate slowly, leave greater stopping distances
and avoid abrupt vehicle maneuvers. You want to keep a
slow constant steady pace. The key is to maintain the
vehicle’s momentum.
•Snow– In heavy snow or for additional control and
traction at slower speeds, shift the transmission to a
low gear and shift the transfer case to 4L (Low) if
necessary. Don’t shift to a lower gear than necessary to
maintain headway. Over-revving the engine can spin
the wheels and traction will be lost. If you start to slow
to a stop, try turning your steering wheel no more than
a
1 4turn quickly back and forth, while still applying
throttle. This will allow the tires to get a freshbite
and help maintain your momentum.
240 STARTING AND OPERATING
CAUTION!
Winching or rocking the vehicle off hard objects
increases the risk of underbody damage.
Hill Climbing
Hill climbing requires good judgment and a good under-
standing of your abilities and your vehicle’s limitations.
Hills can cause serious problems. Some are just too steep
to climb and should not be attempted. You should always
feel confident with the vehicle and your abilities. You
should always climb hills straight up and down. Never
attempt to climb a hill on an angle.
•Before Climbing A Steep Hill– As you approach a
hill consider its grade or steepness. Determine if it is
too steep. Look to see what the traction is on the hill
side trail. Is the trail straight up and down? What is on
top and the other side? Are there ruts, rocks, branchesor other obstacles on the path? Can you safely recover
the vehicle if something goes wrong? If everything
looks good and you feel confident, then change trans-
mission into a lower gear, shift the transfer case into 4L
(Low) and proceed with caution. You should use first
gear and 4L (Low) for very steep hills.
•Driving Up Hill– Once you have determined your
ability to proceed and have shifted into the appropri-
ate gear, line your vehicle up for the straightest
possible run. Accelerate with an easy constant throttle
and apply more power as you start up the hill. Do not
race forward into a steep grade, the abrupt change of
grade could cause you to lose control. If the front end
begins to bounce, ease off the throttle slightly to bring
all four tires back on the ground. As you approach the
crest of the hill ease off the throttle and slowly proceed
over the top. If the wheels start to slip as you approach
the crest of a hill, ease off the accelerator and maintain
headway by turning the steering wheel no more than

POWER STEERING
Your power steering system will provide mechanical
steering capability if power assist is lost.
If for any reason the hydraulic pressure is interrupted, it
will still be possible to steer your vehicle. Under these
conditions you will experience a substantial increase in
steering effort.
MULTI DISPLACEMENT SYSTEM (MDS) - 5.7L
Engine Only
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
TIRE SAFETY INFORMATION
Tire Markings
NOTE:
•P(Passenger)-Metric tire sizing is based on U.S. design
standards. P-Metric tires have the letter “P” molded
into the sidewall preceding the size designation. Ex-
ample: P215/65R15 95H.
