department.
To inspect or replace the filter, do the following:1. Disconnect the Mass Air Flow sensor, PCV hose, and both ducts.
2. Pull the entire system from the top of the engine.
3. Turn the system over and place it on a soft, non‐abrasive surface.
4. Remove the screws that hold the housing and cover together and lift off the housing.
5. Inspect or replace the engine air cleaner/filter.
6. Reverse the steps to reinstall the system. Be sure to reinstall the housing tightly.How to Inspect the Engine Air
Cleaner/Filter (2.0L Engine Only)
See Engine Compartment Overviewon page 6‑16for
the location of the engine air cleaner/filter.
To inspect the air cleaner/filter remove the filter from the
vehicle and lightly shake the filter to release loose dust
and dirt. If the filter remains caked with dirt, a new filter
is required. Never use compressed air to clean the filter.
Because this operation can be a little difficult, you may
choose to have this done at the dealer/retailer service
department.

How to Check
Use a good quality pocket-type gauge to check
tire pressure. You cannot tell if your tires are
properly inflated simply by looking at them.
Radial tires may look properly inflated even
when they are under‐inflated. Check the tire's
inflation pressure when the tires are cold.
Cold means your vehicle has been sitting for
at least three hours or driven no more than
1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gauge firmly onto the valve to get a
pressure measurement. If the cold tire inflation
pressure matches the recommended pressure on
the Tire and Loading Information label, no further
adjustment is necessary. If the inflation pressure
is low, add air until you reach the recommended
amount.
If you overfill the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re‐check the tire pressure with the tire gauge.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in your
vehicle's tires and transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation
pressure for those tires.)
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.
6-64

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‐inflation
has 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.

Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when
a low tire pressure condition exists. If your vehicle has
this feature, TPMS sensors are mounted onto each tire
and wheel assembly, excluding the spare tire and wheel
assembly. The TPMS sensors monitor the air pressure
in the vehicle's tires and transmits the tire pressure
readings to a receiver located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS turns on the low
tire pressure warning light
located on the instrument
panel cluster.
6-65

If the warning light comes on, stop as soon as possible
and inflate the tires to the recommended pressure
shown on the tire loading information label. See
Loading the Vehicle on page 5‑24.
At the same time a message to check the pressure in a
specific tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and
the DIC warning message come on at each ignition
cycle until the tires are inflated to the correct inflation
pressure. Using the DIC, tire pressure levels can be
viewed by the driver. For additional information and
details about the DIC operation and displays seeDIC
Operation and Displays
on page 4‑46and DIC
Warnings and Messages on page 4‑48.
The low tire pressure warning light may come on in cool
weather when the vehicle is first started, and then turn
off as you start to drive. This could be an early indicator
that the air pressure in the tire(s) are getting low and
need to be inflated to the proper pressure. A Tire and Loading Information label shows the size of
your vehicle's original equipment tires and the correct
inflation pressure for your vehicle's tires when they are
cold. See
Loading the Vehicle
on page 5‑24, for an
example of the Tire and Loading Information label and
its location on your vehicle. Also see Inflation - Tire
Pressure on page 6‑63.
Your vehicle's TPMS system can warn you about a low
tire pressure condition but it does not replace normal
tire maintenance. See Tire Inspection and Rotation
on
page 6‑69and Tires on page 6‑54.
Notice: Using non‐approved tire sealants could
damage the Tire Pressure Monitor System (TPMS)
sensors. TPMS sensor damage caused by using an
incorrect tire sealant is not covered by the vehicle
warranty. Always use the GM approved tire sealant
available through your dealer/retailer.
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 6‑78for 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 warning light
flashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message
is also displayed. The low tire warning light and DIC
warning message come on at each ignition cycle until
the problem is corrected. Some of the conditions that
can cause the malfunction light and DIC message to
come on are:
.One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMS
sensor. The TPMS malfunction light and DIC
message should go off once you re‐install the
road tire containing the TPMS sensor.
.The TPMS sensor matching process was started
but not completed or not completed successfully
after rotating the vehicle's tires. The DIC message
and TPMS malfunction light should go off once the
TPMS sensor matching process is performed
successfully. See“TPMS Sensor Matching
Process” later in this section.
.One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your
dealer/retailer for service.
.Replacement tires or wheels do not match your
vehicle's original equipment tires or wheels. Tires
and wheels other than those recommended for
your vehicle could prevent the TPMS from
functioning properly. See Buying New Tires
on
page 6‑72.
.Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or signal
a low tire condition. See your dealer/retailer for service
if the TPMS malfunction light and DIC message comes
on and stays on.
6-67

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.
Any time you replace one or more of the TPMS sensors
or rotate the vehicle's tires, the identification codes
need to be matched to the new tire/wheel location. The
sensors are matched, to the tire/wheel locations, in the
following order: driver side front tire, passenger side
front tire, passenger side rear tire, and driver side rear
tire using a TPMS diagnostic tool. See your dealer/
retailer for service.
The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing the tire's
air pressure. When increasing the tire's pressure, do not
exceed the maximum inflation pressure indicated on the
tire's sidewall. To decrease the tire's air-pressure use
the pointed end of the valve cap, a pencil-style air
pressure gauge, or a key.
You have two minutes to match each tire and wheel
position. If it takes longer than two minutes to match
any tire and wheel position, the matching process stops
and you need to start over.
The TPMS matching process is outlined below:1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the engine off. 3. Press and hold the Remote Keyless Entry (RKE)
transmitter's LOCK and UNLOCK buttons, at the
same time, for about five seconds to start the
TPMS learn mode. The horn sounds twice
indicating the TPMS receiver is ready and in
learn mode.
4. Start with the driver side front tire. The driver side front turn signal also comes on to indicate that
corner's sensor is ready to be learned.
5. Remove the valve cap from the tire's valve stem. Activate the TPMS sensor by increasing or
decreasing the tire's air pressure for about
eight seconds. The horn chirp, can take up to
30 seconds to sound. It chirps one time and then
all the turn signals flash one time to confirm the
sensor identification code has been matched to the
tire/wheel position.
6. The passenger side front turn signal comes on to indicate that corner sensor is ready to be learned.
Proceed to the passenger side front tire and repeat
the procedure in Step 5.
7. The passenger side rear turn signal comes on to indicate that corner sensor is ready to be learned.
Proceed to the passenger side rear tire and repeat
the procedure in Step 5.
