engine BUICK RANDEZVOUS 2005 Owner's Guide

To adjust the HUD so you can see it properly, do the
following:
1. Start your engine and turn the dimmer knob to the
desired HUD image brightness.
The brightness of the HUD image is determined by
the ambient light conditions in the direction your
vehicle is facing and where you have the HUD
dimmer knob set. If you are facing a dark object or a
heavily shaded area, your HUD may anticipate that
you are entering a dark area and may begin to dim.
2. Adjust the driver’s seat. If you change your seat
position, you may have to readjust your HUD.
3. Press the UP or DN buttons until the HUD image is
easy to see and then press the DN button until the
HUD image is as low as possible, but remains
in full view straight ahead near the front bumper.
The HUD image can only be adjusted up and down,
not side-to-side.
4. To turn the image off, turn the dimmer knob
counterclockwise until it stops.
If the sun comes out or it becomes cloudy, you may
need to adjust the HUD brightness again using
the dimmer knob. Polarized sunglasses could make the
HUD image harder to see.When you rst start the vehicle the display will show
BUICK and the Buick logo for a few seconds. If it is cold
outside, this display may stay on for up to a minute.
Clean the inside of the windshield as needed to remove
any dirt or lm that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry
it. Do not spray cleaner directly on the lens because the
cleaner could leak into the unit.
If the ignition is on and you cannot see the HUD image,
check to see if one of the following conditions exist:
The HUD unit is covered
The HUD dimmer knob is adjusted incorrectly
The HUD image is not adjusted to the proper height
Ambient light in the direction your vehicle is
facing, is low
A fuse is blown. SeeFuses and Circuit Breakers on
page 5-105.
If you ever have to have your windshield replaced, be
sure to get one that is designed for the HUD or your
HUD image may look blurred and out of focus.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly – and even
dangerous. So please get to know your warning lights
and gages. They’re a big help.
Your vehicle also has a message center that works
along with the warning lights and gages. SeeMessage
Center on page 3-51.

Retro-Active Reset
The trip odometer has a feature called retro-active reset.
This feature can be used to set the trip odometer to the
number of miles or kilometers driven since the ignition
was last turned on. This can be used if you forget to reset
your trip odometer at the beginning of a trip. To use the
retro-active reset feature, push and hold the trip/reset
button for at least three seconds. The trip odometer will
then display the number of miles or kilometers driven
since the ignition was last turned on and you began
driving. If you use the retro-active reset feature after you
have started the vehicle, but before you begin moving,
the display will show the number of miles or kilometers
you drove during the last ignition cycle. Once you begin
driving, the trip odometer will accumulate mileage. For
example, if you have driven 5.0 miles (8.0 km) since you
started your vehicle, and then activate the retro-active
reset feature, the display will show 5.0 miles (8.0 km).
As you drive, the display will then increase to
5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
