2009 BUICK LACROSSE ECO mode

The player is able to read and play a maximum of
50 folders, 50 playlists, 10 sessions, and 255 les.
Long le names, folder names, or playlist names could
use more disc memory space than necessary. To
conserve disc space, keep the length of the le, folder, or
playlist name brief. MP3 CDs do not require le folders.
The system can support up to 11 folders in depth. The
depth of the folders should be kept down to make it easier
while locating a folder during playback. All items over the
maximum are ignored.
Root Directory
The root directory is treated as a folder. If the root
directory has compressed audio les, the directory
displays as F1 ROOT. All les contained directly under
the root directory are accessed prior to any root directory
folders. However, playlists (Px) always are accessed
before root folders or les.
Empty Directory or Folder
If a root directory or a folder exists somewhere in the
le structure that contains only folders/subfolders and
no compressed les directly beneath them, the player
advances to the next folder in the le structure that
contains compressed audio les and the empty folder
does not display.
No Folder
If a CD has no folder, only compressed les or playlists
are located under the root folder. The next and
previous folder functions have no function on a CD that
is recorded without folders or playlists. When displaying
the name of the folder the radio displays ROOT.
Order of Play
Tracks are played in the following order:
Play begins from the rst track in the rst playlist
and continues sequentially through all tracks in
each playlist. When the last track of the last playlist
has played, play continues from the rst track of
the rst playlist.
If the CD does not contain any playlists, then play
begins from the rst track under the root directory.
When all tracks from the root directory have played,
play continues from les according to their numerical
listing. After playing the last track from the last folder,
play begins again at the rst track of the rst folder or
root directory.
When play enters a new folder, the display does
not automatically show the new folder name unless
the folder mode is chosen as the default display.
See “DISP” later in this section for more information.
The new track name displays.

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 the oil is changed prior to a change engine oil light
or CHANGE OIL SOON message being turned on, reset
the system.
After changing the engine oil, reset the system:
Vehicles with Driver Information Center (DIC)
1. Press the option button on the DIC until
ENGINE OIL MONITOR appears on the
DIC screen.
2. Press the set/reset button to reset the system.
The next screen indicates that the CHANGE
OIL SOON message has been reset.
If the vehicle has the uplevel DIC, when the
gages button is pressed and the OIL LIFE
REMAINING mode appears, it should read
100 percent OIL LIFE REMAINING.
3. Turn the key to LOCK/OFF.
Vehicles without Driver Information Center (DIC)
1. With the engine off, turn the ignition key to
ON/RUN.
2. Fully press and release the accelerator pedal
slowly three times within ve seconds.
3. Turn the key to LOCK/OFF, then start the
vehicle.
If the light or message comes back on when the vehicle
is started, the 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. Recycle it by taking it to a
place that collects used oil.

TPMS Sensor Matching Process
Each TPMS sensor has a unique identication code.
Any time you replace one or more of the TPMS sensors
or rotate the vehicle’s tires, the identication codes need
to be matched to the new tire/wheel position. The sensors
are matched, to the tire/wheel positions, 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 may 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 ination 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 gage, 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 sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.3. Press the Remote Keyless Entry (RKE) transmitter’s
LOCK and UNLOCK buttons at the same time for
approximately ve seconds. The horn sounds twice
to signal the receiver is in relearn mode and the
TPMS sensor matching process can begin.
4. Start with the driver side front tire.
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 10 seconds,
or until a horn chirp sounds. The horn chirp, which
may take up to 30 seconds to sound, conrms that
the sensor identication code has been matched to
the tire/wheel position.
6. Proceed to the passenger side front tire, and repeat
the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat
the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the
procedure in Step 5.
9. After hearing the conrming horn chirp for the driver
side rear tire, the horn chirps two more times to
signal the tire learning process has ended. Turn
the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air
pressure level as indicated on the tire and loading
information label.
11. Put the valve caps back on the valve stems.

Storing a Flat or Spare Tire and
Tools (Base Model)
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
After the compact spare tire has been installed on the
vehicle, store the at tire in the trunk.
When storing a full-size tire, use the extension with
the extension protector, located in the foam holder,
to help avoid wheel surface damage.To store a full-size tire:
1. Install the tools in their original location in the trunk
area and secure.
2. Place the tire valve stem facing down and the
protector/guide placed through a wheel bolt hole.
3. Remove the protector and attach the retainer
securely.
4. Store the cover as far forward as possible.
When storing a compact spare tire in the trunk, put the
protector back in the foam holder.
The compact spare is for temporary use only. Replace
the compact spare tire with a full-size tire as soon as you
can. SeeCompact Spare Tire on page 5-89. Use this as
a guide for storing the compact spare tire and tools.

Gather the important information you will need from
the other driver. Things like name, address, phone
number, driver’s license number, vehicle license
plate, vehicle make, model and model year, Vehicle
Identication Number (VIN), insurance company
and policy number, and a general description of the
damage to the other vehicle.
If possible, call your insurance company from the
scene of the crash. They will walk you through
the information they will need. If they ask for
a police report, phone or go to the police
department headquarters the next day and you
can get a copy of the report for a nominal fee.
In some states/provinces with “no fault” insurance
laws, a report may not be necessary. This is
especially true if there are no injuries and both
vehicles are driveable.
Choose a reputable collision repair facility for your
vehicle. Whether you select a dealer/retailer or a
private collision repair facility to x the damage,
make sure you are comfortable with them.
Remember, you will have to feel comfortable with
their work for a long time.
Once you have an estimate, read it carefully and
make sure you understand what work will be
performed on your vehicle. If you have a question,
ask for an explanation. Reputable shops welcome
this opportunity.
Managing the Vehicle Damage
Repair Process
In the event that your vehicle requires damage repairs,
GM recommends that you take an active role in its
repair. If you have a pre-determined repair facility of
choice, take your vehicle there, or have it towed there.
Specify to the facility that any required replacement
collision parts be original equipment parts, either new
Genuine GM parts or recycled original GM parts.
Remember, recycled parts will not be covered by your
GM vehicle warranty.
Insurance pays the bill for the repair, but you must live
with the repair. Depending on your policy limits, your
insurance company may initially value the repair
using aftermarket parts. Discuss this with your repair
professional, and insist on Genuine GM parts.
Remember if your vehicle is leased you may be
obligated to have the vehicle repaired with Genuine
GM parts, even if your insurance coverage does not
pay the full cost.
If another party’s insurance company is paying for the
repairs, you are not obligated to accept a repair
valuation based on that insurance company’s collision
policy repair limits, as you have no contractual limits with
that company. In such cases, you can have control of
the repair and parts choices as long as cost stays within
reasonable limits.
