10-16 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. Use the SELECT knob to selectOIL LIFE on the DIC menu.
2. Press SELECT to start the OIL LIFE reset procedure.
3. The DIC menu will display “Are
you sure that you want to reset?”
Use SELECT to choose YES to
reset oil life or NO to exit and
return to the previous menu.
4. If YES is selected, the DIC menu will display RESET OIL LIFE for
a short time and then 100% OIL
LIFE will be displayed when
OIL LIFE is successfully reset.
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
See Engine Compartment Overview
on page 10‑10 for the location of the
engine air cleaner/filter.
When to Inspect the Engine Air
Filter
Inspect the air filter at the scheduled
maintenance intervals and replace
it at the first oil change after each
80 000 km (50,000 mi) interval.
See Scheduled Maintenance on
page 11‑2 for more information.
If driving in dusty/dirty conditions,
inspect the air filter at each engine
oil change.
How to Inspect the Engine Air
Filter
To inspect the air filter, remove it
from the engine air cleaner/filter
assembly and lightly shake to
release loose dust and dirt. If the
air filter remains covered with dirt,
a new air filter is required.

Power Steering Fluid
The vehicle is equipped with an
electric power steering system.
No fluid or general maintenance
is required.
Washer Fluid
What to Use
When adding windshield washer
fluid to the vehicle, be sure to read
the manufacturer's instructions
before use. If operating the vehicle
in an area where the temperature
may fall below freezing, use a fluid
that has sufficient protection against
freezing.
Adding Washer Fluid
The WASHER FLUID LOW ADD
FLUID message will appear on
the Driver Information Center
(DIC) when the fluid level is low.
SeeDriver Information Center (DIC)
on page 5‑43 for more information.
Open the cap with the washer
symbol on it. Add washer fluid
until the tank is full. See Engine
Compartment Overview on
page 10‑10 for reservoir location. Notice
.When using concentrated
washer fluid, follow the
manufacturer's instructions
for adding water.
.Do not mix water with
ready-to-use washer fluid.
Water can cause the solution
to freeze and damage the
washer fluid tank and other
parts of the washer system.
Also, water does not clean
as well as washer fluid.
.Fill the washer fluid tank
only three-quarters full
when it is very cold. This
allows for fluid expansion
if freezing occurs, which
could damage the tank if
it is completely full.
.Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system
and paint.

10-56 Vehicle Care
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low
tire pressure telltale when one or
more of your tires is significantly
under‐inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on
a significantly under‐inflated tire
causes the tire to overheat and can
lead to tire failure. Under‐inflation
also reduces fuel efficiency and
tire tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct
tire pressure, even if under‐inflationhas not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start‐ups as
long as the malfunction exists.
When the malfunction indicator
is illuminated, the system may
not be able to detect or signal low
tire pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow
the TPMS to continue to function
properly.

10-58 Vehicle Care
This could be an early indicator that
the air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information
label shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. SeeVehicle Load
Limits on page 9‑14, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10‑54.
The TPMS can warn about
a low tire pressure condition but
it does not replace normal tire
maintenance. See Tire Inspection
on page 10‑61, Tire Rotation on
page 10‑61, and Tires on
page 10‑48. Notice:
Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the
TPMS sensors. TPMS sensor
damage caused by using
an incorrect tire sealant is
not covered by the vehicle
warranty. Always use only
the GM-approved tire sealant
available through your dealer
or included in the vehicle.
Factory-installed Tire Inflator Kits
use a GM-approved liquid tire
sealant. Using non-approved tire
sealants could damage the TPMS
sensors. See Tire Sealant and
Compressor Kit on page 10‑71 for
information regarding the inflator
kit materials and instructions.TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When
the system detects a malfunction,
the low tire pressure warning light
flashes for about one minute and
then stays on for the remainder
of the vehicle on/off cycle. A DIC
warning message also displays.
The malfunction light and DIC
warning message come on at
each vehicle on/off cycle until the
problem is corrected. Some of the
conditions that can cause these to
come on are:
.One of the road tires has
been replaced with the spare
tire, if the vehicle has one.
The spare tire does not
have a TPMS sensor.

Vehicle Care 10-61
Tire Inspection
GM recommends that the
tires, including the spare, be
inspected for signs of wear or
damage at least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord
or fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). The first
rotation is the most important.
SeeScheduled Maintenance on
page 11‑2.
Tires are rotated to achieve a
more uniform wear for all tires.
Any time unusual wear is
noticed, rotate the tires as
soon as possible, and
check the wheel alignment.
See When It Is Time for New
Tires on page 10‑62 andWheel
Replacement on page 10‑67.
Use this rotation pattern when
rotating the tires.
Adjust the front and rear tires
to the recommended inflation
pressure on the Tire and
Loading Information label
after the tires have been
rotated. See Tire Pressure on
page 10‑54 andVehicle Load
Limits on page 9‑14.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑57.

10-62 Vehicle Care
Check that all wheel nuts are
properly tightened. See“Wheel
Nut Torque” underCapacities
and Specifications on
page 12‑2.
{WARNING
Rust or dirt on a wheel,
or on the parts to which it is
fastened, can make wheel
nuts become loose after a
time. The wheel could come
off and cause a crash. When
changing a wheel, remove
any rust or dirt from places
where the wheel attaches to
the vehicle. In an emergency,
a cloth or a paper towel can
be used, however, use a
scraper or wire brush to
remove all rust or dirt. Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change
or tire rotation to prevent
corrosion or rust build-up.
Do not get grease on the flat
wheel mounting surface or
on the wheel nuts or bolts.
When It Is Time for New
Tires
Factors, such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.Treadwear indicators are one way
to tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
or less of tread remaining. See
Tire
Inspection on page 10‑61 and
Tire Rotation on page 10‑61
for additional information.
