NOTE:

• Use of Climatized Ultra Low Sulfur Diesel Fuel or

Number 1 Ultra Low Sulfur Diesel Fuel results in a

noticeable decrease in fuel economy.

• Climatized Ultra Low Sulfur Diesel Fuel is a blend of

Number 2 Ultra Low Sulfur and Number 1 Ultra Low

Sulfur Diesel Fuels which reduces the temperature at

which wax crystals form in fuel.

• The fuel grade should be clearly marked on the pump

at the fuel station.

• The engine requires the use of “Ultra Low Sulfur Diesel

Fuel”

. Use of incorrect fuel could result in engine and

exhaust system damage. Refer to “Fuel Requirements”

in “Starting And Operating” for further information.

Engine Oil Usage
Refer to “Maintenance Procedures” in “Maintaining Your

Vehicle” for the correct engine oil viscosity.

Engine Warm-Up
Avoid full throttle operation when the engine is cold.

When starting a cold engine, bring the engine up to

operating speed slowly to allow the oil pressure to

stabilize as the engine warms up.
If temperatures are below 32°F (0°C), operate the engine

at moderate speeds for five minutes before full loads are

applied.

Engine Idling

Avoid prolonged idling, long periods of idling may be

harmful to your engine because combustion chamber

temperatures can drop so low that the fuel may not burn

completely. Incomplete combustion allows carbon and

varnish to form on piston rings, cylinder head valves,

and injector nozzles. Also, the unburned fuel can enter

the crankcase, diluting the oil and causing rapid wear to

the engine.
