{WARNING
You can lose control of the
vehicle if you try to adjust a
manual driver seat while the
vehicle is moving. The sudden
movement could startle and
confuse you, or make you push a
pedal when you do not want to.
Adjust the driver seat only when
the vehicle is not moving.

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
but 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 3‑16.
To move it down, push down on the
release button (A) and move the
height adjuster to the desired
position. You can move the height
adjuster up by pushing up on the
shoulder belt guide.
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 the 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,
near frontal, or rear crash if the
threshold conditions for pretensioner
activation are met. And, for vehicles
with side impact airbags, safety belt
pretensioners can help tighten the
safety belts in a side crash or a
rollover event.
Pretensioners work only once.
If the pretensioners activate in a
crash, they will need to be replaced,
and probably other new parts for
the vehicle's safety belt system.
See Replacing Safety Belt System
Parts after a Crash on page 3‑23.

Vehicle Care 10-23
{WARNING
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair.
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 in
Capacities 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.
