If the shoulder portion of a
passenger belt is pulled out
all the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
3. Push the latch plate into thebuckle 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 3‑27. Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
If equipped with a shoulder
belt height adjuster, move it
to the height that is right for
you. See
“Shoulder Belt Height
Adjustment” later in this section
for instructions on use and
important safety information.
4. To make the lap part tight, pull up on the shoulder belt.
It may be necessary to pull
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.
To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position. Slide
the latch plate up the safety belt
webbing, when the safety belt is not
in use. The latch plate should rest
on the stitching on the safety belt,
near the guide loop on the side wall.
Before a door is closed, be sure
the safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
safety belt and the vehicle.

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger seating
positions.
Adjust the height so the
shoulder portion of the belt is
on the shoulder and not falling
off of it. The belt should be close
to, but not contacting, the neck.
Improper shoulder belt height
adjustment could reduce the
effectiveness of the safety belt in
a crash. SeeHow to Wear Safety
Belts Properly on page 3‑17.
Press the release button (A) and
move the height adjuster to the
desired position. The adjuster
can be moved up by pushing the
slide/trim up. After the adjuster is
set to the desired position, try to
move it down without pushing the
release button to make sure it has
locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety
belt pretensioners cannot be seen,
they are part of the safety belt
assembly. They can help tighten
the safety belts during the early
stages of a moderate to severe
frontal and near frontal crash if
the threshold conditions for
pretensioner activation are met.
Pretensioners work only once. If the
pretensioners activate in a crash,
the pretensioners and probably
other parts of the vehicle's safety
belt system will need to be replaced.

Parts After a Crash on page 3‑28.

3. Store the head restraint in thetrunk of the vehicle.
4. When the child restraint is removed, reinstall the head
restraint before the seating
position is used.
{WARNING

chance that occupants will suffer
a neck/spinal injury in a crash.
Do not drive until the head
restraints for all occupants are
installed and adjusted properly. To reinstall the head restraint:
1. Insert the head restraint posts
into the holes in the top of the
seatback. The notches (A) on
the posts must face the driver
side of the vehicle. 2. Push the head restraint down.
If necessary, press the height
adjustment release button to
further lower the head restraint.
See Head Restraints on
page 3‑2.
3. Try to move the head restraint to make sure that it is locked in
place.

Vehicle Care 10-25
Some driving conditions or climates
can cause a brake squeal when
the brakes are first applied or
lightly applied. This does not mean
something is wrong with the 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 torque
specifications inCapacities and
Specifications on page 12‑2.
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 that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front
and rear brakes —for the worse.
The braking performance expected
can change in many other ways if
the wrong replacement brake parts
are installed.
Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid
as indicated on the reservoir cap.
See Engine Compartment Overview
on page 10‑6 for the location of the
reservoir.
There are only two reasons why
the brake fluid level in the reservoir
might go down:
.The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.
.A fluid leak in the brake
hydraulic system can also cause
a low fluid level. Have the brake
hydraulic system fixed, since a
leak means that sooner or later
the brakes will not work well.
