light BUICK RANDEZVOUS 2005 Repair Manual

If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. SeeFilling Your Tank on page 5-8. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, misring, hesitation
on acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to x any
mechanical or electrical problems that may have
developed.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON or check engine light is on or not
working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
Highbeam On Light
This light will illuminate
when the headlamp high
beams are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8.

Low Tire Message
Your vehicle may have the check tire pressure system
which can alert you to a large change in the pressure
of one tire. After the system has been properly
calibrated, the low tire pressure message will come on
and a chime will sound if a pressure difference, or
low pressure, is detected in one tire.
The message will stay on until you turn off the ignition
or reset (calibrate) the system. SeeCheck Tire Pressure
System on page 5-62.
If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light on page 3-45.

this time. SeePASS-Key®III on page 2-17for more

All-Wheel Drive Disable Warning
Message
Your vehicle may have this message. If it does, it will
come on when there is a spare tire on the vehicle, or
when the anti-lock brake system warning light comes on,
or when the rear differential uid is overheating. This
message will go out when the differential uid cools.
The all-wheel drive system will be disabled until the
compact spare tire is replaced by a full-size tire. If the
warning message is still on after putting on the full-size
tire, you need to reset the warning message. To
reset the warning message, turn the ignition off and
then back on again. If the message stays on, see your
dealer right away. SeeAll-Wheel Drive (AWD)

DIC Vehicle Personalization
The DIC is used to program the choices of two drivers.
The drivers are recognized as DRIVER 1 or DRIVER 2 in
the DIC display. You will let the DIC know which driver
you are by using your remote keyless entry transmitter.
Each remote keyless entry transmitter was
pre-programmed to belong to DRIVER 1 or DRIVER 2.
Each transmitter may be programmed differently for each
driver’s preferences (lights, doors, horn or activate the
programmed radio stations for driver 1 or driver 2) using
your remote keyless entry transmitter.

and the ignition key is in ON, the DIC will display
the identied driver number. The vehicle will also recall
the vehicle customization features that were last
programmed to correspond to your transmitter.

your transmitter, the DIC will not change drivers
and your vehicle will recall the information from the last
transmitter used.
If your vehicle does not have a DIC, you do not have
available the vehicle customization features using
the remote keyless entry transmitter.
