Driving for Better Fuel

possible.
Avoid fast starts and accelerate
smoothly.
Brake gradually and avoid
abrupt stops.
Avoid idling the engine for long
periods of time.
When road and weather
conditions are appropriate, use
cruise control.
Always follow posted speed
limits or drive more slowly when

inflated.
Combine several trips into a
single trip.
Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.
Follow recommended scheduled
maintenance.

Diesel Particulate Filter

The engine is equipped with a
Diesel Particulate Filter (DPF) that
will filter or trap particulates. The
DPF is under the vehicle in the
exhaust system.
Depending on a number of factors
monitored by the engine computer,
the DPF will need to be cleaned of
accumulated solids. When a
cleaning is needed, the engine
computer will initiate a cleaning
action by warming the exhaust gas
temperature. This feature has been
designed to operate automatically,
with limited operator involvement or
awareness.
