Vehicle Care 249
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 0334. If using this
mixture, nothing else needs to be
added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule 0326.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery coolant
reservoir is located in the engine
compartment. See Engine
Compartment Overview 0242.
1. High Voltage Battery
Coolant Reservoir
2. Power Electronics Coolant Reservoir
Check to see if coolant is visible in
the high voltage battery coolant
reservoir (1). 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 high voltage battery cooling
system supports the operation of
sensitive electronics that are critical
to vehicle operation. 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
Lubricants
0334. If using this
mixture, nothing else needs to be
added.

Engine Coolant
The engine cooling system in the
vehicle is filled with GM Premix
DEX-COOL engine coolant. See
Recommended Fluids and
Lubricants 0334. The coolant
requires changing at certain
intervals. See Maintenance
Schedule 0326. 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 0253.
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.
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 Premix
DEX-COOL coolant.

Engine Oil Change
Every 24 months or when the
CHANGE ENGINE OIL SOON
message displays, change the
engine oil and filter as soon as
possible, within the next 1 000 km/
600 mi. The engine oil and filter
must be changed at least once
every 24 months. After each oil and
filter change, the oil life system must
be reset. See Engine Oil Life
System 0245. More frequent
changes may be required when the
vehicle is exposed to a corrosive
environment, such as areas of high
humidity, along an ocean coast,
and/or areas that apply road salt
during winter.
Your trained dealer technician can
perform this work. If the engine oil
life system is reset accidentally,
service the vehicle within 5 000 km/
3,000 mi since the last service.
Reset the oil life system when the
oil is changed.
Tire Rotation and Required
Services Every 12 000 km/
7,500 mi
Rotate the tires, if recommended for
the vehicle, and perform the
following services. See Tire
Rotation 0284.
. Check engine oil level and oil
life percentage. If needed,
change engine oil and filter, and
reset oil life system. See Engine
Oil 0243 andEngine Oil Life
System 0245.
. Check engine coolant level. See
Engine Coolant 0250.
. Check windshield washer fluid
level. See Washer Fluid 0253.
. Visually inspect windshield wiper
blades for wear, cracking,
or contamination. See Exterior
Care 0314. Replace worn or
damaged wiper blades. See
