Stopping The Engine - Dodge RAM 1500 2018 Diesel Supplement

To decrease the RPM, push and hold the DECEL switch

RPM.

Stopping The Engine

Idle the engine a few minutes before routine shutdown.
After full load operation, idle the engine three to five
minutes before shutting it down. This idle period will
allow the lubricating oil and coolant to carry excess heat
away from the combustion chamber, bearings, internal
components, and turbocharger. This is especially important
for turbocharged, charge air-cooled engines.

NOTE:
• During engine shut down on vehicles equipped with
manual transmissions, it is normal for the diesel engine
to resonate heavily for a moment during engine shut off.
When the engine is connected to a manual transmission,
this resonance causes load gear rattle from the transmis-
sion. This is commonly referred to as "shut down rattle."
The manufacturer recommends performing engine shut
down with the clutch pedal pushed to the floor (clutch
disengaged). When engine shut down is performed in
this manner the rattle is reduced (not eliminated).
• Refer to the following chart for proper engine shutdown.
