Failure to follow these instructions will affect the performance of
the safety belts and increase the risk of personal injury.
Safety belt pretensioner
Your vehicle may be equipped with safety belt pretensioners at the driver
and front outboard passenger seating positions.
The Seat Integrated Restraints (SIR) seat is equipped with a buckle
pretensioner. Do NOT place objects between the seats, this could
interfere with the functioning of the pretensioner. For the SuperCab and
CrewCab base bench seats and all Regular Cab seating positions, the
seatbelts are equipped with a retractor pretensioner.
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 your vehicle has seat integrated restraints you will not have safety belt
height adjustments.
Your vehicle may have safety belt height adjustments for the driver and
front passenger. Adjust the height of the shoulder belt so the belt rests
across the middle of your shoulder.

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.
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.
