height BUICK PARK AVENUE 2004 Owner's Manual

Q:What are the different types of add-on child
restraints?
A:Add-on child restraints, which are purchased by
the vehicle’s owner, are available in four basic
types. Selection of a particular restraint should
take into consideration not only the child’s weight,
height, and age but also whether or not the
restraint will be compatible with the motor vehicle
in which it will be used.
For most basic types of child restraints, there are
many different models available. When purchasing a
child restraint, be sure it is designed to be used
in a motor vehicle. If it is, the restraint will have a
label saying that it meets federal motor vehicle
safety standards.
The restraint manufacturer’s instructions that come
with the restraint state the weight and height
limitations for a particular child restraint. In addition,
there are many kinds of restraints available for
children with special needs.
{CAUTION:
Newborn infants need complete support,
including support for the head and neck.
This is necessary because a newborn infant’s
neck is weak and its head weighs so much
compared with the rest of its body. In a crash,
an infant in a rear-facing seat settles into
the restraint, so the crash forces can be
distributed across the strongest part of an
infant’s body, the back and shoulders. Infants
always should be secured in appropriate infant
restraints.

Be sure to continue scanning your displays, controls
and driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel, you may not see something important, such as a
warning light.
Notice:If you try to use the HUD image as a
parking aid, you may misjudge the distance and
damage your vehicle. Do not use the HUD image as
a parking aid.
The HUD controls are
located in the overhead
console.1. Start your engine and slide the HUD dimmer switch
all the way up.
The brightness of the HUD image is determined by
whether the headlamps are on or off, and where
you have the HUD dimmer switch set.
2. Adjust the seat to a comfortable driving position.
Keep pressing the top arrow on the image height
adjuster to raise the image as far as possible.
3. Keep pressing the bottom arrow on the image
height adjuster to move the image as low as
possible, while still keeping it in full view.
4. Slide the dimmer switch downward until the HUD
image is no brighter than necessary.
To turn the HUD display off, slide the dimmer switch all
the way down.
If the sun comes out, the sky becomes cloudy, or if you
turn your headlamps on, you may need to adjust the
HUD brightness using the dimmer switch. Polarized
sunglasses could make the HUD image harder to see.
To change the display from English to metric units,
push the ENG/MET button located to the left of
the steering column.

Care of the HUD
Clean the inside of the windshield as necessary to
remove any dirt or lm that reduces the sharpness or
clarity of the HUD image.
To clean the HUD lens, spray household glass cleaner
on a soft, clean cloth. Gently wipe and dry the HUD
lens. Do not spray cleaner directly on the lens to avoid
cleaner leaking inside the unit.
If You Can’t See The HUD Image When
the Ignition is On
If the ignition is on and you can’t see the HUD image,
check to see if:
The headlamps are on.
Something is covering the HUD unit.
The HUD dimmer control is adjusted properly.
The HUD image is adjusted to the proper height.
A fuse is blown. SeeFuses and Circuit Breakers on
page 5-99.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD
or your HUD image may look blurred or out of focus.
Ultrasonic Rear Parking Assist
(URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help you
park while in REVERSE (R) and operates only at
speeds less than 3 mph (5 km/h). URPA can help you
avoid colliding with objects such as parked vehicles.
The system can detect objects 5 feet (1.5 m) behind
your vehicle and tell you how close those objects are to
your rear bumper.
The URPA display is located inside the vehicle, above
the rear window. It has three color-coded lights that can
be seen through the rearview mirror.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
CAUTION: (Continued)

Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and go or be heard all the time your vehicle is moving
(except when you are pushing on the brake pedal rmly).
{CAUTION:
The brake wear warning sound means that
soon your brakes will not work well. That
could lead to an accident. When you hear the
brake wear warning sound, have your vehicle
serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.Some driving conditions or climates may cause a brake
squeal when the brakes are rst applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to GM torque specications.
Brake linings should always be replaced as complete
axle sets.
SeeBrake System Inspection on page 6-24.Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
