The 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 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 (if equipped)
If your vehicle has seat integrated restraints you will not have a safety
belt height adjuster.
Regular Cab and SuperCab vehicles have safety belt height adjustments
for the driver and front passenger. SuperCrew vehicles have these
adjustments for the driver, front passenger and rear outboard
passengers. Adjust the height of the shoulder belt so the belt rests
across the middle of your shoulder.

Preparing to tow
Use the proper equipment for towing a trailer, and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle's bumper or attach to the
axle. You must distribute the load in your trailer so that 10%±15% of the
total weight of the trailer is on the tongue.
Load equalizing 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 0±13 mm (0.5 in) of the reference
point. After proper adjustment, the rear bumper should be no higher
than in Step 2.
Adjusting an equalizing hitch so the rear bumper of the vehicle
is higher than it was unloaded will defeat the function of the
load equalizing 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.
