2005 BUICK TERRAZA ignition

Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.Notice:If you keep driving your vehicle with
this light on, after awhile, your emission controls
may not work as well, your fuel economy may not be
as good, and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
This light should come on, as a check to show you it
is working, when the ignition is on and the engine is not
running. If the light does not come on, have it repaired.
This light will also come on during a malfunction in
one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
3-40

The oil light could also come on in three other situations:
When the ignition is on but the engine is not
running, the light will come on as a test to show you
it is working. The light will go out when you turn
the ignition on. If it does not come on with the
ignition on, you may have a problem with the fuse
or bulb. Have it xed right away.
If you are idling at a stop sign, the light may blink
on and then off.
If you make a hard stop, the light may come on for
a moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.

Highbeam On Light
This light will come on
when the high-beam
headlamps or the
Flash-to-Pass feature
is in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8.
Fuel Gage
When the indicator nears empty, you still have a little
fuel left, but you should get more soon.Your fuel gage tells you about how much fuel you have
left when the ignition is on.
Here are four things some owners ask about. All these
things are normal and do not indicate that anything
is wrong with the fuel gage.
At the gas station, the gas pump shuts off before
the gage reads full.
It takes a little more (or less) fuel to ll up than the
gage reads. For example, the gage read half full,
but it took more (or less) than half of the tank’s
capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate empty when the ignition
is turned off.
Low Fuel Warning Light
The light next to the fuel gage will come on briey when
you are starting the engine.
This light comes on when the fuel tank is low on fuel.
To turn it off, add fuel to the fuel tank.

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located in
the instrument panel cluster, below the tachometer. The
DIC buttons are located on the center of the instrument
panel, below the center outlets.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display WELCOME DRIVER (1 or 2)
if a personalized key 1 or 2 is used, and then the
information that was last displayed before the engine
was turned off.
The DIC displays the odometer, trip odometers, fuel
economy, trip computer, vehicle system information, and
compass display, if equipped. It also displays warning
messages if a system problem is detected. In addition,
the DIC displays phone numbers that are called
using the OnStar
®system, if equipped. SeeOnStar®
System on page 2-42.If equipped, the outside air temperature automatically
appears in the bottom right corner of the DIC display
when viewing all of the information screens, except for
the oil life screens. If the outside air temperature is
at or below 37°F (3°C), the temperature reading
will toggle between displaying the outside temperature
and the word ICE for two minutes. If there is a problem
with the system that controls the temperature display,
the letters OC (open circuit) or SC (short circuit)
will appear on the display. If this occurs, have the
vehicle serviced by your GM dealer.
The DIC also allows some features to be customized
or personalized, if equipped. SeeDIC Vehicle
Personalization (Uplevel Only) on page 3-68for more
information.

display CALIBRATION FINISHED.
DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed by the driver to correct the
condition. Multiple messages may appear one after
another.
Some messages may not require immediate action, but
you can press any of the DIC buttons to acknowledge
that you received the message and clear it from the
DIC display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared.If there are any active warning messages when the
vehicle is turned off, two chimes will sound and the
DIC will go into a reminder mode. The reminder
mode displays any active message. If there are multiple
messages, the DIC will display each message for
ve seconds. After each active message is displayed
once, the reminder mode will turn off.
You should take any messages that appear on the
display seriously and remember that clearing the
messages will only make the messages disappear,
not correct the problem.
The following are the possible messages that can be
displayed and some information about them.
A/C OFF FOR ENGINE PROTECTION
This message will display when the engine coolant
becomes hotter than the normal operating temperature.
SeeEngine Coolant Temperature Gage on page 3-39.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.
When the coolant temperature returns to normal, the
air conditioning compressor will turn back on. You can
continue to drive your vehicle.
This message will come on while the ignition is in RUN.
Press any of the DIC buttons to acknowledge this
warning message and to clear it from the screen.
