2. Mix one part neutral detergentinto approximately twenty parts
warm water.
3. Wet a nail brush or another similar brush having soft
bristles (of nylon or the like) in
warm water, and use this to
clean away dirt.
4. Wipe the seat belt dry using a dry cloth, and then allow it to
dry naturally out of direct
sunlight.
5. Check to be sure the seat belt retracts and pulls out correctly. If the above-described upkeep
operations do not improve the
operation of the seat belt through
the retractor, there is a possibility
that the belt is making contact with
the door pillar trim. In this case,
arrange for inspection and
maintenance to be carried out by
your dealer.
If the belt is not winding and
unwinding correctly, or if inspection
reveals problems such as loose
mountings, metal parts deformation,
webbing damage, fraying or
discoloration, arrange for
replacement to be carried out by
your dealer.Child Restraints
Child Restraint Systems
{Warning
Children small enough for child
restraints (as indicated on the
label of such restraints), including
booster seats, should always be
transported in them. Children who
have outgrown child restraint
systems should wear seat belts.
The lap belt should be snug and
positioned low on the abdomen
so that it is below the top of the
hipbone. Otherwise, the belt could
intrude into the child's abdomen
during an accident and cause
personal injury. When a child has
grown enough so that the
shoulder belt can be worn, a
seating position with a shoulder
belt should be chosen whenever
possible.

40 Seats and Restraints
Warning (Continued)
Any unrestrained child could be
injured by striking the vehicle's
interior or by ejection from the
vehicle during an accident or
driving maneuver. Never allow a
child to be held by another
occupant instead of being
properly restrained. If not properly
restrained, the child could strike
the vehicle interior or be crushed
by the person holding the child,
or by other occupants.
Be sure to follow all installation and
use instructions that come with any
child restraint system.
Child restraint systems are designed
to be secured in vehicle seats either
by the lap belt, or the lap portion of
the lap-shoulder belt at that seating
position. The child must also be
secured within the restraint by the
means provided by the child
restraint manufacturer. If the child or the child restraint is not properly
secured, the child risks personal
injury in the event of a collision.
Using a Lap Belt That Has No
Retractor
When securing a child restraint with
the center seat lap belt, pull the
excess webbing through the belt's
adjustment feature, then take these
steps:
.
Once installed, push and pull the
child restraint in all directions to
be sure it is secure. If it comes
loose, flip the end of the belt
with the adjustment feature over
before rebuckling.
. If the child restraint is still not
secure, use the outboard seating
position in the vehicle and
contact your dealer and the child
restraint manufacturer for help.
. Secure the child in the restraint
in accordance with the child
restraint manufacturer's
instructions.
Installation on Outboard Seat
A seat belt locking clip is required
for installation of a child restraint
system on the outboard seat of this
vehicle. A locking clip may usually
be obtained where child restraints
are sold, or by contacting your
dealer for assistance. Make sure the
locking clip is identical to the one
shown on this page. Until you have
the clip, use the child restraint
system only in the center seat.

{Warning
To help avoid personal injury or
death during a collision or sudden
maneuver, always thread both the
lap and shoulder belt through the
locking clip when securing a child
restraint on the outboard seat.
If the clip is not used or installed
properly, the child restraint may
move or tip over when your
vehicle turns or stops abruptly.
Secure the child restraint with the
lap belt portion (1) of the seat belt in
accordance with the restraint
manufacturer's instructions. Then
thread both the lap (1) and shoulder
belt (2) portions through the locking
clip. Push and pull the child restraint
in all directions to be sure it is
secure.

When your child restraint is not
installed, remove the locking clip to
permit normal use of the
lap-shoulder belt. Keep the locking
clip in the glove box to help prevent
its loss.
Child Restraint with Top Tether
{Warning
We do not recommend using a
child restraint that requires the
use of a top tether. There is no
appropriate place to attach a top
tether anchor behind the seat in
this vehicle.

Loading the Vehicle
Overloading
{Warning
Overloading can result in loss of
vehicle control and personal
injury or death, either by causing
component failures or by affecting
vehicle handling. It can also
shorten the service life of your
vehicle.
The components of your truck are
designed to provide satisfactory
service if the vehicle is not loaded in
excess of either the gross vehicle
weight rating (GVWR) or the
maximum front and rear gross axle
weight ratings (GAWRs). These
ratings are listed on the vehicle
identification number (VIN) plate,
which is located on the left side rear
pillar panel below the striker (single cab) or on the left center pillar panel
beside the shoulder seat belt anchor
(crew cab).
Gross vehicle weight (GVW) is the
weight of the originally equipped
vehicle and all items added to it
after it has left the factory. This
would include bodies, lift gates,
refrigeration systems, winches,
booms, etc., the driver and all
occupants, and the load the vehicle
is carrying. The GVW must not
exceed the GVWR. Also, gross
weight on each of the front and rear
axles must not exceed the front and
rear GAWRs respectively.
Your dealer can advise you of the
proper loading conditions for your
vehicle. Using selected heavier
suspension components for added
durability may not increase any of
the weight ratings shown on the VIN
and weight rating plate.

Load Cargo Correctly
{Warning
Overloading can result in a crash
because it places too much strain
on the wheel studs with the result
that they break and the wheels
come off.
The weight of the payload must
be limited within the gross vehicle
weight (GVW) rating and(Continued)
Warning (Continued)
distributed over the front and rear
axles so as not to exceed the
axle capacities.
It is extremely dangerous to
overload the vehicle or to load the
vehicle with the cargo positioned
on one side. Load the vehicle
correctly, observing the maximum
loading capacity.
Incorrect loading can make the
cargo unstable. It can also cause
an overload condition confined to
a small area, resulting in damage
to the cargo bed and frame.
Overloading places undue strain
on vehicle parts. It can shorten
the vehicle's service life and
cause a crash. You and others
could be seriously injured.
