20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.
Check TPMS Warning
If a system fault is detected, the TPM Telltale Light will
flash on and off for 75 seconds and then remain on solid.
The system fault will also sound a chime. In addition, the
EVIC will display aCHECK TPM SYSTEMmessage for
three seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the TPM Telltale Light will no longer
flash, and theCHECK TPM SYSTEMmessage will no
longer display, and a pressure value will display in place
of the dashes. A system fault can occur due to any of the
following:
430 STARTING AND OPERATING

1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles with Full Size Spare
1. The matching full size spare wheel and tire assembly
has a TPM sensor that can be monitored by the TPMS.
2. If you install the full size spare in place of a road tire
that has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, a chime will sound
and the TPM Telltale Light will turn ON. In addition, the
EVIC will display a low pressure message and a graphic
showing the low tire pressure value flashing.3. After driving the vehicle for up to 20 minutes above
15 mph (25 km/h) the TPM Telltale Light will turn OFF,
as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires.

If Equipped
WARNING!
Never operate your vehicle with the TPMS and tire
pressures set to the Light Load Inflation Pressure
settings if carrying more than two occupants (150 lbs
[68 kg] each) plus 200 pounds (91 kg) of cargo. The
vehicle “Light Load Definition” is found in the
Supplemental Tire Pressure Information Label which
is located on the rear face of the driver door opening.
Failure to do so may cause you to lose control resulting
in a collision, causing serious or fatal injury.

STARTING AND OPERATING 431

The TPMS tire light load inflation switch will allow the
driver to switch between the max load inflation pressure
(cold) low pressure warning threshold and the light load
inflation pressure (cold) low pressure warning threshold
depending on the vehicle’s load condition. The Tire and
Loading Information label defines the recommended
front and rear cold tire inflation pressures for the vehicle
when operating in the Max Load condition. A Supple-
mental Tire Pressure Information label is also available
defining Light Load tire inflation pressures when oper-
ating in the Light Load condition. When the tire light
load inflation switch LED is ON, the TPMS is using the
light load inflation pressure (cold) low inflation warning
thresholds.

also equipped to be driven with tire pressures appro-
priate to either a Light Load condition or the vehicle
Max Load condition.
•The tire light load inflation switch will allow the driver
to change between the max load inflation pressure
(cold) low pressure warning threshold and the light
load inflation pressure (cold) low pressure warning
threshold depending on the vehicle’s load condition.
Refer to the “Supplemental Tire Pressure Information”
label for the vehicle’s Light Load inflation pressures
and “Tire and Loading Information” label for the
vehicle’s Max Load inflation pressures.
To switch from the max load inflation pressure (cold) low
pressure warning threshold to the light load inflation
pressure (cold) low pressure warning threshold, begin by
placing the ignition switch in the RUN position. Next,
lower all four road tire pressures to the Light Load
Inflation Pressure values as listed on the Supplemental
Example Supplemental Tire Pressure Label

Tire Pressure Information label. The Supplemental Tire
Pressure Information label is located on the rear face of
the driver door opening. Use an accurate tire gauge to
check the tire pressures when lowering all four tire
pressures. The vehicle may need to be driven above
15 mph (25 km/h) to receive this updated pressure
information. After all four tire pressures have been
lowered to the Light Load inflation pressures, press the
tire light load inflation switch. If the tire light load
inflation switch’s amber colored LED turns ON, the
TPMS is using the light load inflation pressure (cold) low
pressure warning thresholds.
If the tire light load inflation switch amber colored LED
flashes on and off for 10 seconds, after all four tire
pressures have been lowered to the Light Load inflation
pressures, the pressure in any one of the four tires may
not be at the light load inflation pressure (cold) values as
indicated for the Light Load condition as defined on the
Supplemental Tire Pressure Information label located onthe rear face of the driver door. Using an accurate tire
pressure gauge, re-check the tire pressures for the light
load inflation pressure (cold) value.
WARNING!
It is the driver ’s responsibility to change to the max
load inflation pressure (cold) low pressure warning
threshold condition when not driving in the light
load condition as defined as two occupants (150 lbs
[68 kg] each) plus 200 pounds (91 kg) of cargo. The
vehicle “Light Load Definition” is found in the
Supplemental Tire Pressure Information label lo-
cated on the rear face of the driver door. Failure to do
so may cause you to lose control resulting in a
collision, causing serious or fatal injury.
To switch back to the max load inflation pressure (cold)
low pressure warning threshold, press the tire light load
inflation switch. It is not necessary to first fill the tires to
434 STARTING AND OPERATING

the max load inflation pressure (cold) values to switch
the TPMS system to the max load inflation pressure
(cold) low pressure warning threshold. If after pressing
the tire light load inflation switch, and tire pressures are
below the max load inflation pressure (cold) low pressure
warning thresholds, the TPMS low pressure warning
telltale light (located in the instrument cluster) will turn
ON and a chime will sound. The tire pressures are now
required to be inflated to the max load inflation pressure
(cold) values described on the Tire and Loading Informa-
tion label. The Tire and Loading Information label is
located on the drivers side B-pillar. If the tire light load
inflation switch LED turns OFF, the TPMS has been reset
and the TPMS is using the max load inflation pressure
(cold) low pressure warning thresholds.

CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (gas cap).
•A poorly fitting gas cap could let impurities into
the fuel system.
•A poorly fitting gas cap may cause the “Malfunc-
tion Indicator Light (MIL)” to turn on.
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. When the fuel
nozzle “clicks” or shuts off, the fuel tank is full.
WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank is being filled.
(Continued)
WARNING! (Continued)
•Never add fuel to the vehicle when the engine is
running.
•A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
NOTE:
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turn
on if the gas cap is not secured properly. Make sure
that the gas cap is tightened each time the vehicle is
refueled.
•When the fuel nozzle “clicks” or shuts off, the fuel

NOTE:Before installation of a snowplow it is highly
recommended that the owner/installer obtain and follow
the recommendations contained within the current
Dodge Body Builders Guide. See your authorized dealer,
installer or snowplow manufacturer for this information.
There are unique electrical systems that must be con-
nected to properly assure 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 de-
scribed earlier in this manual
CAUTION!
The “Lamp Out” indicator could illuminate if exte-
rior lamps are not properly installed.
Before Plowing
•
Check the hydraulic system for leaks and proper fluid
level.
•Check the mounting bolts and nuts for proper tight-
ness.
•Check the runners and cutting edge for excessive wear.
The cutting edge should be 1/4 to 1/2 in (6 cm to
1.2 cm) above ground in snow plowing position.
•Check that snowplow lighting is connected and func-
tioning properly.

5. Remove the wheel nuts and pull the wheel off. On
single rear-wheel (SRW) trucks, install the spare wheel
and wheel nuts with the cone shaped end of the wheel
nuts toward the wheel. On 3500 dual rear-wheel models
(DRW) the wheel nuts are a two-piece assembly with a
flat face. Lightly tighten the wheel nuts. To avoid the risk
of forcing the vehicle off the jack, do not fully tighten the
wheel nuts until the vehicle has been lowered.
6. Using the wheel wrench, finish tightening the wheel
nuts using a crisscross pattern. The correct wheel nut
tightness is 130 ft lbs (177 N·m) torque (1500 Series), 135 ft
lbs (183 N·m) torque for 2500/3500 single-rear wheel
(SRW) models, and 145 ft lbs (197 N·m) for 3500 dual
rear-wheel models. If in doubt about the correct tight-
ness, have them checked with a torque wrench by your
authorized dealer or at a service station.WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Al-
ways stow the jack parts and the extra tire and wheel
in the places provided.
7. Install the wheel center cap and remove the wheel
blocks. Do not install chrome or aluminum wheel center
caps on the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If the bottle
jack will not lower by turning the dial (thumbwheel) by
hand, it may be necessary to use the jack drive tube in
order to lower the jack. Stow the replaced tire, jack, and
tools as previously described.
9. Adjust the tire pressure when possible.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.
