3. Pick up the latch plate and pull the belt across
you. Do not let it get twisted.
The lap-shoulder belt may lock if you pull the
belt across you very quickly. If this happens,
let the belt go back slightly to unlock it.
Then pull the belt across you more slowly.4. Push the latch plate into the buckle until
it clicks.
Pull up on the latch plate to make sure it
is secure. If the belt is not long enough, see
Safety Belt Extender on page 38.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.
5. Move the shoulder belt height adjuster to
the height that is right for you. Improper
shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a
crash. SeeShoulder Belt Height Adjustment
on page 30.

To unlatch the belt, push the button on the buckle.
The belt should go back out of the way. When
the safety belt is not in use, slide the latch plate up
the safety belt webbing. The latch plate should
rest on the stitching on the safety belt, near
the guide loop on the side wall.
Before you close the door, be sure the belt is
out of the way. If you slam the door on it, you
can damage both the belt and your vehicle.
Shoulder Belt Height Adjustment
Before you begin to drive, move the shoulder belt
height adjuster to the height that is right for you.
Adjust the height so that the shoulder portion of the
belt is centered on your shoulder. The belt should
be away from your face and neck, but not falling off
your shoulder. Improper shoulder belt height
adjustment could reduce the effectiveness of the
safety belt in a crash.
To move it down, press
the release button (A)
and move the height
adjuster to the desired
position. You can move
the height adjuster up
just by pushing up on the
shoulder belt guide.
After you move the height adjuster to where you
want it, try to move it down without pressing the
release button to make sure it has locked into
position.

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 the 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.
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 make a brake stop, your disc
brakes adjust for wear.
