Diesel Exhaust Brake (Engine Braking) - Dodge 2014 Ram 1500 User Manual

6.7L CUMMINS® DIESEL
Cold Start Procedure
• Turn the ignition switch to the ON position. If the Wait To Start
in the cluster, wait for the light to turn off before starting.
• In extremely cold weather below 0°F (-18°C) it may be beneficial to cycle the
manifold heaters twice before attempting to start the engine. This can be
accomplished by turning the ignition OFF for at least five seconds and then back
ON after the "Wait To Start Light" has turned off, but before the engine is started.
However, excessive cycling of the manifold heaters will result in damage to the
heater elements or reduced battery voltage.
• Refer to the Owner's Manual Diesel Supplement on the DVD for further details.
Engine Idling
• Avoid prolonged engine 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, engine
valves, and injector nozzles. Also, the unburned fuel can enter the crankcase,
diluting the oil and causing rapid wear to the engine.
• If the engine is allowed to idle, under some conditions the idle speed may increase
to 900 RPM then return to normal idle speed. This is normal operation.
Remember to disconnect the cord before driving. Damage to the 110–115 volt
electrical cord could cause electrocution.

DIESEL EXHAUST BRAKE (ENGINE BRAKING)

• The Exhaust Brake switch is located on the switch bank below the audio system.
This switch is used to enable exhaust brake modes.
• Pressing the exhaust brake switch once will enable full strength exhaust brake mode,
indicated by a yellow icon in the EVIC. This mode applies full exhaust braking when the
accelerator pedal is released. This is most useful for slowing the vehicle.
• Pressing the exhaust brake switch again will enable the Smart Brake feature,
indicated by a green icon in the EVIC. This feature is intended to maintain the
vehicle speed present when the accelerator pedal is released. However, when the
brakes are applied, full exhaust braking is still enabled to slow the vehicle.
• A third press of the brake switch will turn the exhaust brake off, and will extinguish
the exhaust brake icon in the EVIC.
NOTE:
In general, higher engine speeds result in higher exhaust braking force. For optimum
braking power, it is recommended to use the exhaust brake while in TOW/HAUL mode.
