Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
Consider the following items when computing the
weight on the rear axle of the vehicle:
• The tongue weight of the trailer. • The weight of any other type of cargo or equipment
put in or on your vehicle.
• The weight of the driver and all passengers.
NOTE: Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options, or dealer-installed options,
must be considered as part of the total load on your
vehicle. Refer to the Tire and Loading Information plac-
ard in the Tire Safety Information Section of this manual.

wheel. The nuts should then be tightened to recom-
mended torque. Tighten the nuts to final torque in
increments. Progress around the bolt circle, tightening
the nut opposite to the nut just previously tightened until
final torque is achieved. Recommended torques are

mixture in excess of 5% can negatively impact the on-
engine fuel filter’s ability to separate water from the fuel,
resulting in high pressure fuel system corrosion or dam-
age.
NOTE: As sufficient testing as not been completed,
ethanol blends are not recommended or approved for use
with your Cummins Diesel equipped vehicle.
NOTE: In addition, commercially available fuel addi-
tives are not necessary for the proper operation of your
Cummins Diesel equipped vehicle.
Engine Fuel Filter (Gas Engines)
A plugged fuel filter can cause stalling, limit the speed at
which a vehicle can be driven or cause hard starting.
Should an excessive amount of dirt accumulate in the
fuel tank, frequent filter replacement may be necessary. Spark Plugs (Gas Engines)
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug, malfunctioning spark plugs can damage the cata-
lytic converter. For proper type of replacement spark
plugs, refer to the “Vehicle Emission Control Informa-
tion” label in the engine compartment.
Catalytic Converter (Gas Engines)
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage. MAINTAINING YOUR VEHICLE 413
