system, the vehicle also has a
cooling system for the DMCM
system. This system is serviced
differently than the vehicle's main
cooling system. The DMCM cooling
system includes the DMCM coolant
surge tank, DMCM surge tank

deionized water available at your
dealer. See “ Engine Coolant ” and
“ Cooling System ” in the owner
manual for more information.
