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

BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the seat belt assembly “automatic locking retractor” feature or
any other seat belt function is not operating properly when checked
according to the procedures in theWorkshop Manual. Failure to
replace the belt and retractor assembly could increase the risk of
injury in collisions.
Energy management feature
•This vehicle has a seat 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 seat 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
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.
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.

3. Attach the trailer to the vehicle and adjust the hitch equalizers so that
the front bumper height is within12” (13 mm) of the reference point.
After proper adjustment, the rear bumper should be no higher than in
Step 2.
Note:Adjusting a weight distributing hitch so the rear bumper of the
vehicle is higher than it was unloaded will defeat the function of the
weight distributing hitch and may cause unpredictable handling.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
If you own a trailer with a hydraulic brake system, do not
connect the trailer’s hydraulic brake system directly to your
vehicle’s brake system. The vehicle’s brake system is only designed to
carry the appropriate amount of brake fluid for the vehicle alone.
Connecting a hydraulic trailer braking system could adversely affect
your vehicle’s braking performance.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Integrated trailer brake controller (if equipped)
Your vehicle may be equipped with a fully integrated electronic Trailer
Brake Controller (TBC). When used properly, the TBC helps ensure
smooth and effective trailer braking by powering the trailer’s electric
brakes with a proportional output based on the towing vehicle’s brake
pressure.
