1. To lengthen the lap belt, pull some
webbing out of the shoulder belt
retractor.
2. While holding the webbing below the tongue, grasp the tip (metal portion)
of the tongue so that it is parallel to the
webbing and slide the tongue upward.
3. Provide enough lap belt length so that
the tongue can reach the buckle.
Fastening the Cinch Tongue WARNING: Always drive and ride
with your seatback upright and the lap
belt snug and low across the hips.
1. Pull the lap and shoulder belt from the
retractor so that the shoulder belt
portion of the seatbelt crosses your
shoulder and chest.
2. Be sure the belt is not twisted. If the belt is twisted, remove the twist.
3. Insert the belt tongue into the proper buckle for your seating position until
you hear a snap and feel it latch.
4. Make sure you securely fasten the tongue to the buckle by pulling on the
tongue. While you are fastened in the seatbelt, the
lap and shoulder belt with a cinch tongue
adjusts to your movement. However, if you
brake hard, turn hard, or if your vehicle
receives an impact of
5 mph (8 km/h) or
more, the seatbelt locks and helps reduce
your forward movement.
Using Seatbelts During Pregnancy WARNING:
Always ride and drive
with your seatback upright and properly
fasten your seatbelt. Fit the lap portion
of the seatbelt snugly and low across
the hips. Position the shoulder portion of
the seatbelt across your chest. Pregnant
women must follow this practice. See
the following figure. Pregnant women should always wear their
seatbelt. Position the lap belt portion of a
combination lap and shoulder belt low
across the hips below the belly and worn
as tight as comfort allows. Position the
shoulder belt to cross the middle of the
shoulder and the center of the chest.

Seatbelt Locking Modes
WARNING: If your vehicle is
involved in a crash, have the seatbelts
and associated components inspected
as soon as possible. Failure to follow this
instruction could result in personal injury
or death.
All safety restraints in the vehicle are
combination lap and shoulder belts. The
driver seatbelt has the first type of locking
mode. The front outermost passenger and
rear seat seatbelts have both types of
locking modes described as follows:
Vehicle Sensitive Mode
This is the normal retractor mode, which
allows free shoulder belt length
adjustment to your movements and
locking in response to vehicle movement.
For example, if the driver brakes suddenly,
turns a corner sharply, or the vehicle
receives an impact of about
5 mph
(8 km/h) or more, the combination
seatbelts lock to help reduce forward
movement of the driver and passengers.
In addition, the retractor is designed to lock
if you pull the webbing out too quickly. If
the seatbelt retractor locks, slowly lower
the height adjuster to allow the seatbelt
to retract. If the retractor does not unlock,
pull the seatbelt out slowly then feed a
small length of webbing back toward the
stowed position. For rear seatbelts, recline
the rear seat backrest or push the seat
backrest cushion away from the seatbelt.
Feed a small length of webbing back
toward the stowed position. Automatic Locking Mode
In this mode, the shoulder belt
automatically pre-locks. The belt still
retracts to remove any slack in the
shoulder belt. The automatic locking mode
is not available on the driver seatbelt.
When to Use the Automatic Locking
Mode
Use this mode any time you install a child
restraint in a front outermost passenger
seating position in a Regular Cab,
SuperCab, SuperCrew or any rear seating
position of a SuperCab or SuperCrew. The
optional front center seatbelt has a cinch
mechanism. Properly restrain children 12
years old and under in a rear seat whenever
possible.
How to Use the Automatic Locking
Mode
1. Buckle the combination lap and
shoulder belt.
2. Grasp the shoulder portion and pull downward until you pull the entire belt
out.
3. Allow the belt to retract. As the belt retracts, you will hear a clicking sound.
This indicates the seatbelt is now in the
automatic locking mode.
