Winter Front Cover Usage; Battery Blanket Usage - Dodge RAM 1500 2018 Diesel Supplement

128 STARTING AND OPERATING
NOTE:
• Use of Climatized Ultra Low Sulfur Diesel Fuel or
Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.
• Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low
Sulfur Diesel Fuels which reduces the temperature at
which wax crystals form in fuel.
• The fuel grade should be clearly marked on the pump at
the fuel station.
• The engine requires the use of "Ultra Low Sulfur Diesel
Fuel". Use of incorrect fuel could result in engine and
exhaust system damage. Refer to "Fuel Requirements"
in "Technical Specifications" for further information.
• If climatized or diesel Number 1 ULSD fuel is not
available, and you are operating below (20°F/-6°C), in
sustained arctic conditions, Mopar Premium Diesel Fuel
Treatment (or equivalent) is recommended to avoid
gelling (see Fuel Operating Range Chart).
Engine Oil Usage
Refer to "Dealer Service" in "Servicing And Maintenance"
for the correct engine oil viscosity.

Winter Front Cover Usage

A winter front or cold weather cover is to be used in ambient
temperatures below 32°F (0°C), especially during extended
idle conditions. This cover is equipped with four flaps for
managing total grille opening in varying ambient tempera-
tures. If a winter front or cold weather cover is to be used the
flaps should be left in the full open position to allow air flow
to the charge air cooler and automatic transmission oil cooler.
When ambient temperatures drop below 0°F (-17°C) the four
flaps need to be closed. A suitable cold weather cover is
available from your Mopar dealer.

Battery Blanket Usage

A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°C). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized Mopar dealer.
