The power electronics and charger
modules are cooled using the same
coolant loop.
The power electronics and charger
modules in the vehicle are kept
below a maximum temperature.
If the temperature rises above this
temperature, the electric cooling
fans will turn on and cool the
coolant until the correct temperature
is reached.
What to Use
The power electronics and charger
modules coolant reservoir in the
vehicle is filled with a 50/50 mixture
of DEX-COOL engine coolant and
deionized water. If using this
mixture, nothing else needs to be
added.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The power electronics and charger
modules coolant reservoir is located
on the driver side of the engine
compartment. See Engine
Compartment Overview on
page 10 8 for more information on
location.
Check to see if coolant is visible in
the power electronics and charger
modules coolant reservoir. If coolant
is visible but the coolant level is
below the cold fill line, there could
be a leak in the cooling system.

The power electronics and charger
modules coolant should only be
serviced by a qualified technician.
