Starting and Stopping the Engine STOPPING THE ENGINE Turn the ignition to the off position. To prolong engine life (especially after extended high speed, high ambient temperature, or high GVW/GCW operation, such as heavy loads and/or heavy trailers), it is recommended that a hot engine be idled for 3-5 minutes. This allows the turbocharged engine to cool down. For more information on GVW/GCW, see the Load Carrying chapter in your Owner's Manual. COLD WEATHER OPERATION Note: Idling in cold weather does not heat the engine to its normal operating temperature. Long periods of idling, especially in cold weather, can cause a buildup of deposits which can cause engine damage. Changing to a lighter grade engine oil also makes starting easier under these conditions. Refer to Engine oil specifications in the Maintenance chapter of this supplement. Diesel fuel is adjusted seasonally for cold temperatures. Diesel fuel which has not been properly formulated for the ambient conditions may gel which can clog the fuel filters. One indication that the fuel filter(s) may be clogged is if the engine starts, stalls after a short time, and then does not restart. If you have been using biodiesel, you may need to use a fuel with lower biodiesel content, try another brand, or discontinue using biodiesel. Do not use alcohol based additives to correct fuel gelling. This may result in damage to the fuel injectors/system. Use the proper anti-gel & performance improver product as listed in the Technical Specifications section in the Capacities and Specifications chapter. Your vehicle is equipped with a diesel fuel conditioner module (DFCM) which recirculates fuel from the engine to help prevent fuel filter clogging. To avoid engine fuel starvation during cold weather operation of 32°F (0°C) or below, it is recommended that the fuel level in your tank should not be allowed to drop below 1⁄4 full. This helps prevent air from entering the fuel system and stalling the engine. Your vehicle is equipped with a an SCR system which uses diesel exhaust fluid (DEF) to operate properly. DEF must be replenished at certain intervals. When filling the vehicle's DEF tank in cold weather, special care must be taken to prevent damage to the DEF tank. For proper cold weather fill procedure, see Selective Catalytic Reduction (SCR) System in the Fuel and Refueling chapter. 10 2013 Diesel (67l) Supplement, 1st Printing USA (fus)

STOPPING THE ENGINE
Turn the ignition to the off position.
To prolong engine life (especially after extended high speed, high
ambient temperature, or high GVW/GCW operation, such as heavy loads
and/or heavy trailers), it is recommended that a hot engine be idled for
3-5 minutes. This allows the turbocharged engine to cool down. For more
information on GVW/GCW, see the

COLD WEATHER OPERATION
Note:
Idling in cold weather does not heat the engine to its normal
operating temperature. Long periods of idling, especially in cold weather,
can cause a buildup of deposits which can cause engine damage.

Diesel fuel is adjusted seasonally for cold temperatures. Diesel fuel which
has not been properly formulated for the ambient conditions may gel
