3-16 Seats and Restraints
To unlatch the belt, push the button
on the buckle.
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. See
How
to Wear Safety Belts Properly on
page 3‑13.
Move the height adjuster up to the
desired position by pushing up on
the height adjuster. After the height adjuster is set to the
desired position, try to move it down
without pressing the release
button (A) to make sure it has
locked into position. Press the
release button to lower the height
adjuster.
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. And, if the
vehicle has side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or a rollover event.

10-30 Vehicle Care
Headlamp Aiming
The headlamp aiming system has
been preset at the factory.
If the vehicle is damaged in an
accident, the aim of the headlamps
may be affected and adjustment
may be necessary.
It is recommended that a dealer
adjust the headlamps. To re-aim the
headlamps yourself, use the
following procedure.
The vehicle should be properly
prepared as follows. The vehicle:
.Should be placed so the
headlamps are 7.6 m (25 ft) from
a light colored wall.
.Must have all four tires on a
level surface which is level all
the way to the wall.
.Should be placed so it is
perpendicular to the wall or other
flat surface.
.Should not have any snow, ice,
or mud on it.
.Should be fully assembled and
all other work stopped while
headlamp aiming is being
performed.
.Should be normally loaded with
a full tank of fuel and one person
or 75 kg (160 lbs) sitting in the
driver's seat.
.Tires should be properly inflated.
Headlamp aiming is done with the
vehicle's low-beam headlamps. The
high-beam headlamps will be
correctly aimed if the low-beam
headlamps are aimed properly. To adjust the vertical aim, do the
following:
1. Open the hood. See
Hood on
page 10‑5 for more information.
2. Locate the aim dot on the lens of
the low‐beam headlamp.
3. Measure the distance from the ground to the aim dot on the
low‐beam headlamp. Record the
distance.
