Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that
indicates when to change the engine oil and
filter. This is based on a combination of
factors which include engine revolutions,
engine temperature, and miles driven. Based
on driving conditions, the mileage at which
an oil change is indicated can vary
considerably. For the oil life system to work
properly, the system must be reset every
time the oil is changed.
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 may
indicate that an oil change is not necessary
for up to a year. The engine oil and filter
must be changed at least once a year and
at this time the system must be reset. Your
dealer has trained service people who willperform 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. Using the DIC controls on the right side of the steering wheel, display
REMAINING OIL LIFE on the DIC. See
Driver Information Center (DIC) 0111.
When remaining oil life is low, the
CHANGE ENGINE OIL SOON message will
appear on the display.
2. Press
Von the DIC controls and hold
down for a few seconds to clear the
CHANGE ENGINE OIL SOON message and
reset the oil life at 100%. Be careful not to reset the oil life display
accidentally at any time other than after
the oil is changed. It cannot be reset
accurately until the next oil change.
The system is reset when the CHANGE
ENGINE OIL SOON message is off.
If the CHANGE ENGINE OIL SOON message
comes back on when the vehicle is started,
the engine oil life system has not been
reset. Repeat the procedure.
Automatic Transmission Fluid
A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the
vehicle to your dealer and have it repaired
as soon as possible.
Caution
Use of the incorrect automatic
transmission fluid may damage the
vehicle, and the damage may not be
covered by the vehicle warranty. Always
use the correct automatic transmission
fluid. See Recommended Fluids and
Lubricants 0334.
See your dealer to have the fluid and filter
changed at the intervals listed in the
Maintenance Schedule 0330.

Engine Air Filter Life System
If equipped, this feature provides the engine
air filter's remaining life and best timing for
a change. The timing to change an engine
air filter depends on driving and
environmental conditions.
When to Change Engine Air Filter
When the Driver Information Center (DIC)
displays a message to replace the engine air
filter at the next oil change, follow this
timing.
When the DIC displays a message to replace
the engine air filter soon, replace the engine
air filter at the earliest convenience. The
system must be reset after the engine air
filter is changed.
If the DIC displays a message to check the
engine air filter system, see your dealer.
How to Reset Engine Air Filter Life
System
To reset:1. Place the vehicle in P (Park).
2. On the infotainment home screen, select Vehicle Status > Fluids & Filters > Engine
Air Filter Life. See
Vehicle Status 0113 for instructions
on navigating and selecting items.
3. Touch Reset.
4. Touch Yes to confirm.
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
0 263.
When to Inspect the Engine Air Cleaner/
Filter
.For intervals on changing and inspecting
the engine air filter, see Maintenance
Schedule 0330.
.If equipped with Engine Air Filter Life
System, see Engine Air Filter Life System
0 267.
.If driving in very dusty areas, follow the
engine air filter inspecting and changing
intervals, see Maintenance Schedule
0 330.
How to Inspect/Replace the Engine Air
Cleaner/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 cleaner/filter. Lightly
tap and shake the engine air cleaner/filter
(away from the vehicle), to release dust and
dirt. Inspect the engine air cleaner/filter for
damage, and replace if damaged. Do not
clean the engine air cleaner/filter or
components with water or compressed air.
To inspect or replace the engine air cleaner/
filter:
1. Remove the six screws on top of the
engine air cleaner/filter housing.
2. Lift the air cleaner/filter cover housing away from the engine.

3. Pull out the filter.
{Warning
If part replacement is necessary, the part
must be replaced with one of the same
part number or with an equivalent part.
Use of a replacement part without the
same fit, form, and function may result
in personal injury or damage to the
vehicle.
4. Inspect or replace the engine air cleaner/ filter.
5. Reverse Steps 1–3 to reinstall the filter cover housing.
6. If equipped, reset the engine air filter life system after replacing the engine air
filter. See Engine Air Filter Life System
0 267.
{Warning
Operating the engine with the air
cleaner/filter off can cause you or others
to be burned. Use caution when working
on the engine. Do not start the engine or
(Continued)
Warning (Continued)
drive the vehicle with the air cleaner/
filter off, as flames may be present if the
engine backfires.
Caution
If the air cleaner/filter is off, dirt can
easily get into the engine, which could
damage it. Always have the air cleaner/
filter in place when driving.
Cooling System
The cooling system allows the engine to
maintain the correct working temperature.
1. Electric Engine Cooling Fan (Outof View)
2. Coolant Surge Tank and Pressure Cap
{Warning
An underhood electric fan 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.
{Warning
Do not touch heater or radiator hoses,
or other engine parts. They can be very
hot and can burn you. Do not run the
engine if there is a leak; all coolant could
leak out. That could cause an engine fire
and can burn you. Fix any leak before
driving the vehicle.
Engine Coolant
The engine cooling system in the vehicle is
filled with DEX-COOL engine coolant mixture.
This coolant needs to be checked and
changed at appropriate levels. See
Recommended Fluids and Lubricants 0334
and Maintenance Schedule 0330.

.When the REPLACE AT NEXT OIL CHANGE
message displays, the engine air filter
should be replaced at the next engine oil
change. When the REPLACE ENGINE AIR
FILTER SOON message displays, the
engine air filter should be replaced at the

.Passenger compartment air filter
replacement (or every 24 months,
whichever occurs first). More frequent
replacement may be needed if the vehicle
is driven in areas with heavy traffic, poor
air quality, areas with high dust levels or
are sensitive to environmental allergens.
Filter replacement may also be needed if
you notice reduced airflow, windows
fogging up, or odors. Your local GM
Service location can help you determine
when it is the right time to replace your
filter. Every 96 000 km (60,000 mi)
.Replace spark plugs. Inspect spark plug
wires and/or boots.
Every 161 000 km (100,000 mi)
.Replace hood and/or body lift support gas
struts. Or every 10 years, whichever
comes first. See Gas Strut(s)0277.
Every 240 000 km (150,000 mi)
.Change rear axle fluid, if equipped with
AWD. Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water can
overcome the seals and contaminate the
transfer case fluid. Contaminated fluid will
decrease the life of the transfer case and/
or axles and should be replaced.
.Drain and fill engine cooling system. Or
every six years, whichever comes first.
See Cooling System 0268.
