Vehicle Care 251
The high voltage battery cooling
system should only be serviced by a
qualified technician.
Cooling System (Power
Electronics and Charger
Modules)
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
threshold. If the coolant temperature
rises above this temperature
threshold, 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 GM Premix
DEX-COOL engine coolant. See
Recommended Fluids and
Lubricants0329. If using this
mixture, nothing else needs to be
added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule 0321.
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
in the engine compartment. See
Engine Compartment Overview
0240.
1. High Voltage Battery
Coolant Reservoir
2. Power Electronics Coolant Reservoir
Check to see if coolant is visible in
the power electronics coolant
reservoir (2). If coolant is visible but
the coolant level is below the cold
fill line on the side of the reservoir,
there could be a leak in the cooling
system.
The power electronics cooling
system supports the operation of
sensitive electronics.

252 Vehicle Care
The power electronics cooling
system should only be serviced by a
qualified technician.
Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
If the decision is made not to lift the
hood when this warning appears,
get service help right away. See
Roadside Assistance Program
0339.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
do not continue to run the vehicle,
and have the vehicle serviced.
Caution
Do not run the engine when there
is a leak in the hybrid cooling
system. This can cause a loss of
all coolant and can damage the
system and the vehicle. Have any
leaks fixed right away.
Washer Fluid
What to Use
When adding windshield washer
fluid to the vehicle, be sure to read
the manufacturer's instructions
before use. If operating the vehicle
in an area where the temperature
may fall below freezing, use a fluid
that has sufficient protection against
freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See Engine
Compartment Overview 0240 for
reservoir location.
Caution
. Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
. Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
