{Warning
The electric fans under the hood
can start up even when the
engine is not running and can
cause injury. Keep hands,
clothing, and tools away from any
underhood electric fan.
If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be up to
the cold fill line. If it is not, there
might be a leak at the radiator
hoses, heater hoses, radiator, water
pump, or somewhere else in the
cooling system.
{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned. (Continued)
Warning (Continued)
Do not run the vehicle if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
If there seems to be no leak, with
the engine on, check to see if the
cooling fans are running. If the
engine is overheating, the fans
should be running. If it is not, the
vehicle needs service. Turn off the
vehicle.
Cooling System (High
Voltage Battery)
During vehicle operation and also
during charging, the high voltage
battery cells in the vehicle are kept
within a normal operating
temperature range. If the high
voltage battery cell temperature
rises above the normal operating
temperature range, the battery
cooling system turns on the air conditioning compressor and cools
the coolant until the correct battery
cell temperature is reached. If the
high voltage battery cell temperature
falls below the normal operating
temperature range, a high voltage
heater, located in the battery, heats
the coolant until the correct battery
cell temperature is reached.
During high voltage battery system
cooling, you may feel temperature
changes at the air vents due to the
extra load on the system.
What to Use
The high voltage battery coolant
reservoir in the vehicle is filled with
GM Premix DEX-COOL
®engine
coolant. See Recommended Fluids
and Lubricants 0324. If using this
mixture, nothing else needs to be
added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule 0315.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.

1. High Voltage BatteryCoolant Reservoir Cold
Fill Line
2. Power Electronics Coolant Reservoir Cold Fill Line
Check to see if coolant is visible in
the power electronics coolant
reservoir. If coolant is visible but the
coolant level is below the cold fill
line (2), there could be a leak in the
cooling system.
The power electronics cooling
system supports the operation of
sensitive electronics. The power electronics cooling
system should only be serviced by a
qualified technician.
Engine Coolant
The engine cooling system in the
vehicle is filled with GM Premix
DEX-COOL engine coolant. See
Recommended Fluids and
Lubricants
0324. The coolant
requires changing at certain
intervals. See Maintenance
Schedule 0315.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating 0242.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
(Continued)
Warning (Continued)
The coolant warning system is set
for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get too
hot but you would not get the
overheat warning. The engine
could catch fire and you or others
could be burned. Use GM
Premixed DEX-COOL coolant.
Use GM Premix DEX-COOL engine
coolant. If using this mixture,
nothing else needs to be added.
This mixture:
. Gives freezing protection down
to−37 °C (−34 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
. Protects against rust and
corrosion.
. Will not damage aluminum parts.
. Helps keep the proper engine
temperature.
