attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0245.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.

244 Vehicle Care
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
0 242 for the location of the engine
oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle. 2. Pull out the dipstick and wipe it
with a clean paper towel or
cloth, then push it back in all
the way. Remove it again,
keeping the tip down, and
check the level.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
and then recheck the level. See
“Selecting the Right Engine Oil” in
this section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications 0338.
Caution
Do not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level above the
operating range, i.e., the engine
has so much oil that the oil level
gets above the cross-hatched
area that shows the proper
operating range, the engine could
be damaged. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
See Engine Compartment Overview
0 242 for the location of the engine
oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.

246 Vehicle Care
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to
two years. The engine oil and filter
must be changed at least once
every two years and, at this time,
the system must be reset. Your
dealer has trained service people
who will perform this work and reset
the system. It is also important to
check the oil regularly over the
course of an oil drain interval and
keep it at the proper level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:1. Select REMAINING OIL LIFE on the DIC menu.
2. Press and hold
Vfor several
seconds while the Oil Life
display is active to reset the Oil
Life system.
3. 100% OIL LIFE will be displayed when the oil life
system is successfully reset.
The oil life system can also be reset
as follows: 1. Turn the ignition to ON/RUN with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds. If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
Engine Air Cleaner/Filter
The engine air cleaner/filter is in the
engine compartment on the
passenger side of the vehicle, see
Engine Compartment
Overview
0242.
When to Inspect the Engine Air
Filter
For intervals on changing and
inspecting the engine air cleaner/
filter, see Maintenance
Schedule 0326.
How to Inspect the Engine Air
Filter
Do not start the engine or have the
engine running with the engine air
cleaner/filter housing open. Before
removing the engine air cleaner/
filter, make sure that the engine air
cleaner/filter housing and nearby
components are free of dirt and
debris. Remove the engine air

248 Vehicle Care
Cooling System (Engine)
1. Engine Cooling Fans (Outof View)
2. Engine Coolant Surge Tank and Pressure Cap
{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.
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 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.
