5. Locate the vertical adjuster (2)
for each headlamp. Adjust the aim
by turning the adjuster control
either clockwise (to adjust up) or
counterclockwise (to adjust down).
6. In addition to the horizontal line
marked in step 2, a pair of vertical
lines (5) must be marked at the
center line of the headlamps on the
wall or screen.
7. On the wall or screen, locate the high intensity area of the beam
pattern. The left edge of the high intensity area should be even with the
vertical line corresponding to the headlamp under adjustment. If the left
edge of the high intensity area is not even with the vertical line, follow
the next step to adjust it.
8. Locate the horizontal adjuster (1) for each headlamp. Turn it
clockwise or counterclockwise, to place the left edge of the high
intensity area even with the vertical line corresponding to the headlamp
under adjustment.

WARNING:BELT AND RETRACTOR ASSEMBLY MUST BE
REPLACED if the safety belt assembly “automatic locking
retractor” feature or any other safety belt function is not operating
properly when checked by an authorized dealer. Failure to replace the
belt and retractor assembly could increase the risk of injury in
collisions.
Energy management feature
•This vehicle has a safety belt system with an energy management
feature at the front outboard seating positions to help further reduce
the risk of injury in the event of a head-on collision.
•The front outboard safety belt systems have a retractor assembly that
is designed to pay out webbing in a controlled manner. This feature is
designed to help reduce the belt force acting on the occupant’s chest.
Safety belt pretensioner (if equipped)
Your vehicle is equipped with safety belt retractor pretensioners at the
driver and front outboard passenger seating positions.
The driver and front outboard passenger safety belt pretensioners are
designed to activate only during certain frontal or near-frontal collisions
with sufficient longitudinal deceleration. A safety belt pretensioner is a
device which tightens the webbing of the lap and shoulder belts during
some collisions in such a way that they fit more snugly against the body.
The driver and front outboard passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the vehicle
is involved in a collision that results in the activation of the safety belt
pretensioners. Refer to theSafety belt maintenancesection in this
chapter.
WARNING:Failure to replace the safety belt assembly under
the above conditions could result in severe personal injuries in
the event of a collision.
Front safety belt height adjustment
The front outboard seating positions are equipped with safety belt height
adjusters.
Adjust the height of the shoulder belt so the belt rests across the middle
of your shoulder.

WARNING:Towing trailers beyond the maximum tongue weight
exceeds the limit of the towing system and could result in
vehicle structural damage, loss of vehicle control and personal injury.
Weight distributing hitch
When hooking up a trailer using a load equalizing hitch, always use the
following procedure:
1. Park the unloaded vehicle on a level surface. With the ignition on and
all doors closed, allow the vehicle to stand for several minutes so that it
can level.
2. Measure the height of a reference point on the front and rear bumpers
at the center of the vehicle.
3. Attach the trailer to the vehicle and adjust the hitch equalizers so that
the front bumper height is within
1 2inch (13 mm) of the reference
point. After proper adjustment, the rear bumper should be no higher
than in Step 2.
