Tire Pressure : Displays the approximate
pressures of all four tires. Tire pressure is
displayed in either kilopascal (kPa) or in
pounds per square inch (psi). If the pressure
is low, the value for that tire is shown in
amber. See Tire Pressure Monitor System
0 255 and
Tire Pressure Monitor Operation 0255.
When selected, the following options may
be chosen in the dialog: Relearn Tire
Pressure, Turn Off/On Leak Detection, Reset
Leak Detection, and Show in Cluster. When
enabled, you will receive alerts when a fast

Detection speeds shown are either Tire Leak
or Fast Leak. When disabled, you will still
receive low tire pressure alerts. However,
you will stop receiving additional alerts
when a tire is leaking air.

Maintenance
Passenger Compartment Air Filter
The filter reduces dust, pollen, and other
airborne irritants from outside air that is
pulled into the vehicle. The filter should be
replaced as part of routine scheduled
maintenance.
SeeMaintenance Schedule 0286.
See your dealer regarding replacement of
the filter.
Service
All vehicles have a label underhood that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be
serviced by trained and certified technicians.
The air conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be replaced
by a new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires periodic
maintenance. See
Maintenance Schedule
0 286.
Caution
Damage caused by improper refrigerant
usage could lead to costly repairs and
may not be covered by the vehicle
warranty. Refrigerant systems should
only be serviced by qualified personnel.
Always use the correct refrigerant.

Engine Oil
To ensure proper engine performance and
long life, careful 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. SeeEngine Oil Life System 0223.
.Always dispose of engine oil properly. See
“What to Do with Used Oil” in this
section.
Checking Engine Oil
Check the engine oil level regularly, every
650 km (400 mi), especially prior to a long
trip. The engine oil dipstick handle is a loop.
See Engine Compartment Overview 0218 for
the location.
{Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
If a low oil Driver Information Center (DIC)
message displays, check the oil level.
Follow these guidelines:
.To get an accurate reading, park the
vehicle on level ground. Check the engine
oil level after the engine has been off for
at least two hours. Checking the engine oil level on steep grades or too soon after
engine shutoff can result in incorrect
readings. Accuracy improves when
checking a cold engine prior to starting.
Remove the dipstick and check the level.
.If unable to wait two hours, the engine
must be off for at least 15 minutes if the
engine is warm, or at least 30 minutes if
the engine is not warm. Pull out the
dipstick, 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.

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 the 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 the Engine Air Filter Life
System
To reset:1. Place the vehicle in P (Park).
2. Select Engine Air Filter Life on the DIC menu. See Driver Information Center
(DIC) 0109. 3. Press
lor the thumbwheel to move to
the Reset/Disable display area. Select
Reset then press
lor press the
thumbwheel. Then press Yes to confirm
the reset.
4. 100% AIR FILTER LIFE will be displayed when the Engine Air Filter Life System is
successfully reset.
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
0 218.
When to Inspect the Engine Air
Cleaner/Filter
If the vehicle is not equipped with the
engine air filter life system, see
Maintenance Schedule 0286 for intervals on
inspecting and replacing the engine air
cleaner/filter.
How to Inspect 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. Do
not clean the engine air cleaner/filter with
water or compressed air.
To inspect or replace the air cleaner/filter:
1. Remove the two push pins.

2. Press a hook both sides and disassembletwo hooks.
3. Disassemble the duct.
4. Remove four screws, tilt the cover, andslide it out of the assembly.
{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.
5. Inspect or replace the engine air cleaner/ filter. 6. Lower the cover, slide it into the
assembly, then secure with the screws.
7. If equipped, reset the engine air filter life system after replacing the engine air
filter. See Engine Air Filter Life System
0 224.
See Maintenance Schedule 0286 for
replacement intervals.
{Warning
Operating the engine with the air
cleaner/filter off can cause you or others
to be burned. The air cleaner not only
cleans the air; it helps to stop flames if
the engine backfires. Use caution when
working on the engine and do not drive
with the air cleaner/filter off.
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.

.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
earliest convenience. Reset the engine air

.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)0236.
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.
