Battery Location - RAM promaster 2015 Owner's Manual

318 WHAT TO DO IN EMERGENCIES
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle's battery, even when not
in use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough without engine operation,
the vehicle's battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.

Battery Location

There are two remote jump starting posts under the hood
which is the recommended jump start location. If access
to the battery is needed, an access panel on the driver's
side floor will allow for battery access.
