2005 BUICK PARK AVENUE start stop button

If a door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. Your
vehicle’s lamps will ash and the horn will sound
for 30 seconds. The lamps and horn will then turn off to
save battery power.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a key or use the manual
door lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct key if the
alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door keyafterthe doors are closed.
Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set off the alarm.
If you set off the alarm by accident, unlock any door
with your key. You can also turn off the alarm by
pressing the unlock button on the remote keyless entry
transmitter. The alarm won’t stop if you try to unlock
a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, roll down the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors using the
power door lock switch while the door is open, or
using the remote keyless entry transmitter.
3. Get out of the car, close the door and wait for the
SECURITY light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should, but the
vehicle’s lamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeFuses and Circuit Breakers on page 5-92.
If the alarm does not sound or the vehicle’s lamps do
not ash, the vehicle should be serviced by a GM dealer.

it which reects the following messages:
EXP
(Export ID) Warning Message
23 DOOR AJAR
24 TRUNK AJAR
25 WINDSHIELD WASHER FLUID LOW
36 ENGINE OIL LOW – CHECK LEVEL
54 SERVICE STABILITY SYSTEM

The EXP codes are used to make translation from
English to other languages easier.
Pressing any of the DIC control buttons will remove
the messages or warnings from the DIC display.SERVICE STABILITY SYSTEM – 54:If you ever see
the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system: stop, turn off the engine, then start the
engine again. If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem.
You should see your GM dealer for service. Reduce
your speed and drive accordingly.
STABILITY SYSTEM ACTIVE – 55:You may see the
STABILITY SYSTEM ACTIVE message. It means
that an advanced, computer-controlled system has come
on to help your vehicle continue to go in the direction
in which you are steering. This stability enhancement
system activates when the computer senses that
your vehicle is just starting to spin, as it might if you hit
a patch of ice or other slippery spot on the road.
When the system is on, you may hear a noise or feel a
vibration in the brake pedal. This is normal.
When the STABILITY SYSTEM ACTIVE message is on,
you should continue to steer in the direction you want
to go. The system is designed to help you in bad
weather or other difficult driving situations by making the
most of whatever road conditions will permit. If the
STABILITY SYSTEM ACTIVE message comes on, you
will know that something has caused your vehicle to
start to spin, so you should consider slowing down.

Engine Oil Life System
When to Change Engine Oil (Vehicles
With the GM Oil Life System)
If so equipped, your vehicle has a computer system that
lets you know when to change the engine oil and
lter. This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil change will be
indicated can vary considerably. For the oil life system to
work properly, you must reset the system every time
the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE OIL SOON message
will come on. Change your oil as soon as possible within
the next two times you stop for fuel. It is possible that,
if you are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, your engine oil and
lter must be changed at least once a year and at
this time the system must be reset. Your dealer has
GM-trained service people who will perform this
work using genuine GM parts and reset the system. It is
also important to check your oil regularly and keep it
at the proper level.If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.How to Reset the Oil Life System
The GM Oil Life System calculates when to change
your engine oil and lter based on vehicle use. Anytime
your oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
CHANGE ENGINE OIL SOON message being
turned on, reset the system.
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Oil Life
System, do the following:
1. Display OIL LIFE INDEX on the DIC.
2. Press and hold the DIC RESET button for
more than ve seconds. The oil life will change
to 100%.
3. 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.
