Note: We have attempted to cover as much information as possible. However, this information does not cover all the unique variations that a vehicle chassis may present. Note that illustrations are typical but may not reflect all the variations of assembly. All data provided is based on information that was current at time of release.

General Fuel and Oil CAUTION Diesel engines for 2006 and later model year vehicles are designed to operate only with ultra low sulfur diesel (ULSD) fuel. Use of fuel other than ULSD will reduce the efficiency and durability of the engine, permanently damage the advanced emission control systems, reduce fuel economy and possibly prevent the engine from running at all. Manufacturer's war- ranties are likely to be rendered void by usage of improper or incorrect fuel, and usage of fuels other than ULSD fuel in die- sel-powered vehicles is illegal and punishable with civil penalties. Use of fuel additives to compensate for the lower sulfur content is NOT recommended by MACK Trucks, Inc.

Fuel sold for use in diesel-powered engines for 2006 and later model year vehicles may only contain a maximum sulfur con- tent of 0.0015% by weight. This was done to reduce particle emissions in the exhaust. Bio Diesel The only biodiesel fuel approved by MACK Trucks, Inc. for use in MACK Engines is soy methyl ester (SME or SOME) in blends up to B20 concentration (20% blend). Note: Although higher concentrations are available, concentration up to B20 (maximum) are the only blends currently ap- proved by MACK Trucks, Inc. Greenhouse Gas 2017 Maximum limit will be B10 concentration (10% blend).

Engine Oil EO-O Premium Plus (or VDS-4) diesel engine oil is mandatory for use in all 2017 emission compliant MACK engines. Chas- sis equipped with a 2017 emission compliant engine, which can be identified by the presence of an aftertreatment selective catalytic reduction (SCR) system, also require the use of Ultra Low Sulfur Diesel (ULSD) fuel. EO-O Premium Plus oils ex- ceed the new American Petroleum Institute (API) service category CJ-4.

Engine Overview CAUTION DO NOTcrank the engine for more than 30 seconds at a time; wait 15 minutes after each try to allow the starter to cool. Failure to follow these instructions could cause starter damage. Note: Some starters are equipped with starter protection. If the engine is running, the starter temperature is too high, the transmission is not in neutral or the clutch pedal is not depressed, starter engagement is inhibited. Allow the engine to slow down and idle for 3 to 5 minutes before shutting it off. This allows the turbocharger to cool down and the cooling system to dissipate the engine heat. Switch the engine off by turning the ignition key to the OFF position.

CAUTION Shutting off an engine immediately after high speed or full load operation can damage the turbocharger and cause heat stress in the engine. Always let the engine idle for 3 to 5 minutes before shutting it off. MACK Trucks, Inc. does not recommend the use of winterfronts, shutters or any other shield in front of the grille or radiator package under normal circumstances. Today's electronically controlled engines are designed to operate in cold tempera- tures without a winterfront. These devices, if not used properly, can cause higher exhaust gas temperatures, power loss, ex- cessive fan usage, failure of the charge-air-cooler (CAC) and a reduction in fuel economy.

Winterfronts can be used in the wintertime during very cold weather if used properly. In these cases, engine coolant and intake air temperatures must also be carefully monitored and controlled. Please see your authorized MACK Truck dealer for recommended winterfronts. CAUTION MACK is now using the ambient air temperature (AAT) sensor for on board diagnostic (OBD) monitoring. If a customer in- stalls a winterfront or blocks the radiator opening and blocks airflow to the sensor, they will likely set an OBD diagnostic trouble code (DTC) for inaccurate sensor data due to restricted airflow across the sensor.

Introduction of ether or similar starting aids could cause a fire or explosion resulting in severe property damage, serious personal injury or death.

Engine Shutdown System The engine shutdown system will automatically derate or stop the engine when one or more of the conditions listed below reaches a critical stage: High Engine Coolant Temperature (ECT) Low Engine Oil Pressure (EOP) Low Engine Coolant Level (ECL) High Crankcase Pressure (CCP) When the shutdown is activated, the telltales come on along with display symbols and the buzzer is also activated. After a brief time, the engine shuts down. Find a safe place to pull off the road as soon as possible. After the engine has been shut down by the system, turn the ignition key to the OFF position.

If necessary, the engine can be restarted for a brief time so that the vehicle may be pulled off the road. The alarm will remain activated until repairs have been made to correct the problem that caused the shutdown. CAUTION Continuously restarting the engine once the shutdown system is active may result in severe engine damage. Refer to the driver information display (DID) manual for information about the display symbols.

Vehicle crash can occur.
