SAFETY BELT HEIGHT ADJUSTMENT
WARNING:Position the safety belt height adjusters so that the
belt rests across the middle of your shoulder. Failure to adjust
the safety belt properly could reduce the effectiveness of the seat belt
and increase the risk of injury in a crash.
Adjust the height of the shoulder belt so the belt rests across the middle
of your shoulder. To adjust the shoulder belt height:
1. Squeeze the side release buttons
and slide the height adjuster up or
down.
2. Pull down on the height adjuster
to make sure it is locked in place.
Second Row Comfort Guide
WARNING: Position the safety belt comfort guide so that the
belt rests across the middle of your shoulder. Failure to adjust
the safety belt properly could reduce the effectiveness of the safety belt
and increase the risk of injury in a crash.
The second row outboard lap and
shoulder belt is equipped with a belt
comfort guide. This guide is attached
to the quarter trim panel. Use it to
adjust the comfort of the shoulder belt
for smaller occupants in the outboard
second row seats.

ADJUSTING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, an authorized dealer should
check the alignment of your headlamps.
Vertical Aim Adjustment
Before aim adjustment, disable the air suspension system. Refer to
Message centerin theDriver Controls chapter.
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away. •(A) 8 feet (2.4 meters)
• (B) Center height of lamp to
ground
• (C) 25 feet (7.6 meters)
• (D) Horizontal reference line
2. Measure the height from the
center of your headlamp (indicated
by a 3.0 millimeter circle on the
lens) to the ground and mark an
8 foot (2.4 meter) horizontal
reference line on the vertical wall or screen at this height (a piece of
masking tape works well).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood. Cover one of the headlamps so no light from that lamp
hits the wall.
4. On the wall or screen you will
observe a light pattern with a
distinct horizontal edge towards the
right. If this edge is not at the
horizontal reference line, the beam
will need to be adjusted so the edge
is at the same height as the
horizontal reference line.
