2007 DODGE POWER WAGON fuel pressure

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 members 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.

INSTRUMENT CLUSTER DESCRIPTION
1. Check Gages
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gages indicate a reading either too high or too low.
Examine the gages carefully, and follow the instructions
above for each indicated problem.
NOTE:When the ignition switch is turned to OFF, the
Fuel Gage, Voltmeter, Oil Pressure and Engine Coolant
Temperature gages may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltage Gauge
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. Ifthe pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the ªCheck Gagesº indicator will illuminate
and a single chime will sound. The ªCheck Gagesº
indicator may also illuminate prior to the voltage gauge
moving out of normal range. In either case, see you local
authorized Dealer for system service.
3. Turn Signal Indicators
Lights in instrument cluster flash when outside turn
signals are operating.
4. Tachometer
The tachometer indicates engine speed in revolutions per
minute.

1. SafetyÐ
WARNING!
²Improperly inflated tires are dangerous and can cause
accidents.
²Under inflation increases tire flexing and can result in
tire failure.
²Over inflation reduces a tire's ability to cushion shock.
Objects on the road and chuckholes can cause damage
that result in tire failure.
²Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
²Over inflated or under inflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
²Unequal tire pressures from one side of the vehicle to
the other can cause the vehicle to drift to the right or left.
²Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
2. EconomyÐ
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under inflation, also increases
tire rolling resistance and results in higher fuel consump-
tion.
3. Ride Comfort and Vehicle StabilityÐ
Proper tire inflation contributes to a comfortable ride.
Over inflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed either on
the face of the driver's door or on the driver's side ªBº
pillar.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than the

At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant bottle, brake master
cylinder, and transmission and add as needed.
²Check all lights and all other electrical items for correct
operation.
At Each Oil Change
²Change the engine oil filter.
²Lubricate the front driveshaft grease fitting and tie rod
end links.
²Inspect the exhaust system.
²Inspect the brake hoses.
²Inspect the UÐjoints and front suspension compo-
nents.
²Check the automatic transmission fluid level.
²Check the manual transmission fluid level.
²Check the coolant level, hoses, and clamps.
²Lubricate Front Drive Shaft Fitting.
