Canada/Mexico-15883563) - 2022 - CRC - 11/19/21
84 Seats and Restraints
According to accident statistics, children and
infants are safer when properly restrained in
a child restraint system or infant restraint
system secured in a rear seating position.
SeeWhere to Put the Restraint 077 for
additional information.
Securing a Child Restraint Designed for
the LATCH System
{Warning
A child could be seriously injured or killed
in a crash if the child restraint is not
properly attached to the vehicle using
either the LATCH anchors or the vehicle
seat belt. Follow the instructions that
came with the child restraint and the
instructions in this manual.
{Warning
Do not attach more than one child
restraint to a single anchor, except for
the center top tether anchors in the crew
cab models. Attaching more than one
child restraint to a single anchor could
cause the anchor or attachment to come
loose or even break during a crash.
(Continued)
Warning (Continued)
A child or others could be injured. To
reduce the risk of serious or fatal injuries
during a crash, attach only one child
restraint per anchor.
{Warning
Children can be seriously injured or
strangled if a shoulder belt is wrapped
around their neck. The shoulder belt can
tighten but cannot be loosened if it is
locked. The shoulder belt locks when it is
pulled all the way out of the retractor.
It unlocks when the shoulder belt is
allowed to go all the way back into the
retractor, but it cannot do this if it is
wrapped around a child’s neck. If the
shoulder belt is locked and tightened
around a child’s neck, the only way to
loosen the belt is to cut it.
Buckle any unused seat belts behind the
child restraint so children cannot reach
them. Pull the shoulder belt all the way
out of the retractor to set the lock, and(Continued)
Warning (Continued)
tighten the belt behind the child restraint
after the child restraint has been
installed.
Caution
Do not let the LATCH attachments rub
against the vehicle’s seat belts. This may
damage these parts. If necessary, move
buckled seat belts to avoid rubbing the
LATCH attachments.
Do not fold the rear seat cushion when
the seat is occupied. Do not fold the
empty rear seat with a seat belt buckled.
This could damage the seat belt or the
seat. Unbuckle and return the seat belt to
its stowed position, before folding
the seat.
If you need to secure more than one child
restraint in the rear seat, see Where to Put
the Restraint 077.
Regular Cab Models 1. For models without a rear seat, forward-facing child restraints should
only be installed in the right front

Driving and Operating 219
Using heavier suspension components
to get added durability might not
change the weight ratings. Ask your
dealer to help load the vehicle the
right way.
{Warning
Things you put inside the vehicle can
strike and injure people in a sudden
stop or turn, or in a crash.
.Put things in the cargo area of the
vehicle. Try to spread the weight
evenly.
.Never stack heavier things, like
suitcases, inside the vehicle so
that some of them are above the
tops of the seats.
.Do not leave an unsecured child
restraint in the vehicle.
.When you carry something inside
the vehicle, secure it whenever
you can.
.Do not leave a seat folded down
unless you need to. There is also important loading
information for off-road driving in this
manual. See
“Loading the Vehicle for
Off-Road Driving“ underOff-Road
Driving 0208.
Two-Tiered Loading
Depending on the model of the pickup,
an upper load platform can be created
by positioning three or four 5 cm (2 in)
by 15 cm (6 in) wooden planks across
the width of the pickup box. The planks
must be inserted in the pickup box
depressions.
When using this upper load platform,
be sure the load is securely tied down
to prevent it from shifting. The load's
center of gravity should be positioned
in a zone over the rear axle. The zone is
located in the area between the front
of each wheel well and the rear of each
wheel well. The center of gravity height
must not extend above the top of the
pickup box flareboard. Any load that extends beyond the
vehicle's taillamp area must be properly
marked according to local laws and
regulations.
Remember not to exceed the Gross Axle
Weight Rating (GAWR) of the front or
rear axle.
Add-On Equipment
When carrying removable items, a limit
on how many people carried inside the
vehicle may be necessary. Be sure to
weigh the vehicle before buying and
installing the new equipment.
Caution
Overloading the vehicle may cause
damage. Repairs would not be covered by
the vehicle warranty. Do not overload the
vehicle.
Remember not to exceed the Gross Axle
Weight Rating (GAWR) of the front or
rear axle.

Vehicle Care 421
3. Start on the outside edge of the soil andgently rub toward the center. Fold the
cleaning cloth to a clean area frequently
to prevent forcing the soil into the
fabric.
4. Continue gently rubbing the soiled area until there is no longer any color
transfer from the soil to the cleaning
cloth.
5. If the soil is not completely removed, use a mild soap solution followed only
by plain water.
If the soil is not completely removed, it may
be necessary to use a commercial upholstery
cleaner or spot lifter. Test a small hidden
area for colorfastness before using a
commercial upholstery cleaner or spot lifter.
If ring formation occurs, clean the entire
fabric or carpet.
After cleaning, use a paper towel to blot
excess moisture.
Cleaning High Gloss Surfaces and Vehicle
Information and Radio Displays
Use a microfiber cloth on high gloss surfaces
or vehicle displays. First, use a soft bristle
brush to remove dirt that can scratch the
surface. Then gently clean by rubbing with a
microfiber cloth. Never use window cleaners or solvents. Periodically hand wash the
microfiber cloth separately, using mild soap.
Do not use bleach or fabric softener. Rinse
thoroughly and air dry before next use.
Caution
Do not attach a device with a suction cup
to the display. This may cause damage
and would not be covered by the vehicle
warranty.
Instrument Panel, Leather, Vinyl, Other
Plastic Surfaces, Low Gloss Paint
Surfaces, and Natural Open Pore Wood
Surfaces
Use a soft bristle brush to remove dust from
knobs and crevices on the instrument
cluster. Use a soft microfiber cloth
dampened with water to remove dust and
loose dirt. For a more thorough cleaning,
use a soft microfiber cloth dampened with a
mild soap and water solution.
Caution
Soaking or saturating leather, especially
perforated leather, as well as other
interior surfaces, may cause permanent
damage. Wipe excess moisture from
(Continued)
Caution (Continued)
these surfaces after cleaning and allow
them to dry naturally. Never use heat,
steam, or spot removers. Do not use
liquids that contain alcohol or solvents on
leather seats. Do not use cleaners that
contain silicone or wax-based products.
Cleaners containing these solvents can
permanently change the appearance and
feel of leather or soft trim, and are not
recommended.
Do not use cleaners that increase gloss,
especially on the instrument panel. Reflected
glare can decrease visibility through the
windshield under certain conditions.
Caution
Use of air fresheners may cause
permanent damage to plastics and
painted surfaces. If an air freshener
comes in contact with any plastic or
painted surface in the vehicle, blot
immediately and clean with a soft cloth
dampened with a mild soap solution.
Damage caused by air fresheners would
not be covered by the vehicle warranty.
