Ram Trucks 2015 ProMaster Commercial - User Guide - Manual (Page 61)

Extreme Cold Weather
This vehicle has three heating elements; one engine block heater (a resistance heater
installed in the water jacket of the engine) and two transmission heaters (one
resistance heater installed under the oil reservoir of the hydraulic actuation system
and one on the differential cover of the transmission). They require a 110–115 Volt
AC electrical outlet with a grounded, three-wire extension cord. Their use is
recommended for environments that routinely fall below -10°F (-23°C). They should
be used when the vehicle has not been running overnight or longer periods and
should be plugged in two hours prior to start. Their use is required for cold starts with
temperatures under -20°F (-29°C).
A 12 Volt heater built into the fuel filter housing aids in preventing fuel gelling. It is
controlled by a built-in thermostat. This diesel pre-heat system improves engine
starting and reduces the amount of white smoke generated by a warming engine.
NOTE:
• The engine is designed to work at an ambient temperature ranging from -22°F to
+ 122°F (-30°C to + 50C°). Rubber, pipes, timing belt cover and electronic
devices are not designed to work out of this range.
• The engine and transmission block heater cord is a factory installed option. If your
vehicle is not equipped, heater cords are available from your authorized MOPAR ®
dealer.
In the case of LOW temperature after Starting, the Automated Manual Transmission
may not be able to engage first gear. In this case a message "Shift not allowed"
appears. In this situation use the engine block heater.
Water In Fuel Message
If a Generic Warning Light appears in the cluster and a “Service Fuel Filter” message
appears in EVIC, the fuel/water separator will need to be drained immediately to
prevent engine damage. Please see your authorized dealer for draining the fuel
filter/water separator and fuel filter replacement.
