How to Reset the Engine Oil
Life System
The Engine Oil Life System calculates when to
change the engine oil and lter based on vehicle
use. Whenever the oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where you
change the oil prior to a CHANGE ENGINE OIL
SOON message in the Driver Information
Center (DIC) being turned on, reset the system.
After the oil has been changed, the CHANGE
ENGINE OIL SOON message must be reset:
1. Turn the key to the RUN position without
starting the engine.
2. Press the INFO button on the Driver
Information Center (DIC) until OIL LIFE
REMAINING is displayed. SeeDIC Controls
and Displays on page 240.
3. Press and hold the INFO RESET button until
100% is displayed. This resets the oil life
indicator.
4. Turn the key to OFF.If the CHANGE ENGINE OIL SOON message
comes back on when you start your vehicle, the
engine oil life system has not reset. Repeat
the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that can
be unhealthy for your skin and could even cause
cancer. Do not let used oil stay on your skin for very
long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly
dispose of clothing or rags containing used engine
oil. See the manufacturer’s warnings about the use
and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil
from the lter before disposal. Never dispose of oil
by putting it in the trash, pouring it on the
ground, into sewers, or into streams or bodies of
water. Instead, recycle it by taking it to a place
that collects used oil. If you have a problem
properly disposing of used oil, ask your
dealer/retailer, a service station, or a local
recycling center for help.

Power Steering Fluid
The power steering uid
reservoir is located next
to the underhood
fuse block on the
passenger’s side of the
vehicle. SeeEngine
Compartment Overview
on page 364for
more information on
location.
When to Check Power Steering Fluid
It is not necessary to regularly check power
steering uid unless you suspect there is a leak in
the system or you hear an unusual noise. A
uid loss in this system could indicate a problem.
Have the system inspected and repaired.
How to Check Power Steering Fluid
To check the power steering uid, do the following:
1. Turn the key off and let the engine
compartment cool down.
2. Wipe the cap and the top of the
reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the
uid level on the dipstick.
The level should be at the FULL COLD mark. If
necessary, add only enough uid to bring the level
up to the mark.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 475.
Always use the proper uid. Failure to use the
proper uid can cause leaks and damage hoses
and seals.

Resetting the TPMS Sensor
Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors, rotate the vehicle’s tires, or
install a full-size spare that has a TPMS sensor,
the sensor’s identication codes will need to
be matched to the new tire/wheel position. Each
tire/wheel position is matched to the TPMS sensor
using a TPMS diagnostic tool. See your GM
dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
air pressure, do not exceed the maximum tire
pressure indicated on the tire’s sidewall.
You will have two minutes to match the rst
tire/wheel position, and ve minutes overall, to
match all four tire/wheel positions. If it takes longer
than two minutes, to match the rst tire and
wheel, or more than ve minutes to match all
four tire and wheel positions the matching process
stops and you will need to start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Press the Driver Information Center (DIC)
vehicle information button until the PRESS
VTO RELEARN TIRE POSITIONS displays.
4. Press the set/reset button to allow the system
to learn the tire positions. The horn will sound
twice to indicate that the TPMS is ready,
and then the message TIRE LEARNING
ACTIVE will display. The sensor matching
process can begin.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the valve stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for
ve seconds, or until a horn chirp sounds. The
horn chirp, which may take up to 30 seconds,
conrms that the sensor identication code has
been matched to this tire position. To decrease
the tire’s air-pressure use the pointed end of
the valve cap, a pencil-style air pressure gage
or a key.

(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings and clamps; replace with
genuine parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and
wiper blades, if contaminated. Replace wiper
blades that are worn or damaged. See Windshield
Wiper Blade Replacement on page 400and
Windshield and Wiper Blades on page 445for
more information.
(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced. Also
look for any opened or broken airbag coverings,
and have them repaired or replaced. The
airbag system does not need regular maintenance.(f)Lubricate all key lock cylinders. Lubricate all
hinges and latches, including those for the hood,
rear compartment, glove box door, and console
door. More frequent lubrication may be required
when exposed to a corrosive environment.
Applying silicone grease on weatherstrips with a
clean cloth will make them last longer, seal better,
and not stick or squeak.
(g)If you drive regularly under dusty conditions,
the lter may require replacement more often.
(h)Change automatic transmission uid and lter
if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Professional vehicle uses, such as limousine
service.
Uses such as high performance operation.

Ignition Transmission Lock Check
While parked, and with the parking brake set, try
to turn the ignition to OFF in each shift lever
position.
The ignition should turn to OFF only when the
shift lever is in PARK (P).
The ignition key should come out only in OFF.
Contact your dealer/retailer if service is required.
Parking Brake and Automatic
Transmission Park (P) Mechanism Check
{CAUTION:
When you are doing this check, your
vehicle could begin to move. You or
others could be injured and property
could be damaged. Make sure there is
room in front of your vehicle in case it
begins to roll. Be ready to apply the
regular brake at once should the vehicle
begin to move.Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake’s holding ability:
With the engine running and transmission in
NEUTRAL (N), slowly remove foot pressure
from the regular brake pedal. Do this until the
vehicle is held by the parking brake only.
To check the PARK (P) mechanism’s holding
ability: With the engine running, shift to
PARK (P). Then release the parking brake
followed by the regular brake.
Contact your dealer/retailer if service is required.
Underbody Flushing Service
At least every spring, use plain water to ush any
corrosive materials from the underbody. Take
care to clean thoroughly any areas where mud and
other debris can collect.
