4. If equipped with a shoulder beltheight 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.

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 that the
shoulder portion of the belt is
centered on the shoulder. The
belt should be away from the face
and neck, but not falling off of the
shoulder. Improper shoulder belt
height adjustment could reduce the
effectiveness of the safety belt in a
crash.

Headlamp Aiming

factory and should need no further
adjustment.

in a crash, the headlamp aim may
be affected and adjustment may be
necessary.
If oncoming vehicles flash their high
beams at you, this may also mean
the vertical aim needs to be
adjusted.

is taken to your dealer for service if
the headlamps need to be re-aimed.
It is possible however, to re-aim the
headlamps as described.The vehicle should be:.Placed so the headlamps are
7.6 m (25 ft) from a light colored
wall or other flat surface.

the wall or other flat surface.

on it.

properly inflated, and all other
work stopped while headlamp
aiming is being performed.
