Your vehicle has an OBD Data Link
Connector (DLC) that is used in
conjunction with a diagnostic scan tool for
vehicle diagnostics, repairs and
reprogramming services. Installing an
aftermarket device that uses the DLC
during normal driving for purposes such as
remote insurance company monitoring,
transmission of vehicle data to other
devices or entities, or altering the
performance of the vehicle, may cause
interference with or even damage to
vehicle systems. We do not recommend
or endorse the use of unapproved
aftermarket plug-in devices. The vehicle
Warranty will not cover damage caused
by an aftermarket plug-in device.
Notice to Owners of Pickup Trucks
and Utility Type Vehicles
WARNING: Utility vehicles have a
significantly higher rollover rate than
other types of vehicles.
Before you drive your vehicle, please read
this Owner ’s Guide carefully. Your vehicle
is not a passenger car. As with other
vehicles of this type, failure to operate this
vehicle correctly may result in loss of
vehicle control, vehicle rollover, personal
injury or death.
Using Your Vehicle With a
Snowplow
Do not use this vehicle for
snowplowing.
Your vehicle does not have a snowplowing
package.
Using Your Vehicle as an
Ambulance
Do not use this vehicle as an
ambulance. Your vehicle does not have the Ambulance
Preparation Package.
MOBILE COMMUNICATIONS
EQUIPMENT
WARNING:
Driving while
distracted can result in loss of vehicle
control, crash and injury. We strongly
recommend that you use extreme
caution when using any device that may
take your focus off the road. Your
primary responsibility is the safe
operation of your vehicle. We
recommend against the use of any
hand-held device while driving and
encourage the use of voice-operated
systems when possible. Make sure you
are aware of all applicable local laws
that may affect the use of electronic
devices while driving.
Using mobile communications equipment
is becoming increasingly important in the
conduct of business and personal affairs.
However, you must not compromise your
own or others’ safety when using such
equipment. Mobile communications can
enhance personal safety and security when
appropriately used, particularly in
emergency situations. Safety must be
paramount when using mobile
communications equipment to avoid
negating these benefits. Mobile
communication equipment includes, but
is not limited to, cellular phones, pagers,
portable email devices, text messaging
devices and portable two-way radios.

GENERAL INFORMATION
See the following sections for directions
on how to properly use safety restraints
for children.
WARNING: Always make sure your
child is secured properly in a device that
is appropriate for their height, age and
weight. Child safety restraints must be
bought separately from your vehicle.
Failure to follow these instructions and
guidelines may result in an increased risk
of serious injury or death to your child. WARNING: All children are shaped
differently. The National Highway Traffic
Safety Administration and other safety
organizations, base their
recommendations for child restraints on
probable child height, age and weight
thresholds, or on the minimum
requirements of the law. We recommend
that you check with a NHTSA Certified
Child Passenger Safety Technician (CPST) to make sure that you properly
install the child restraint in your vehicle
and that you consult your pediatrician to
make sure you have a child restraint
appropriate for your child. To locate a
child restraint fitting station and CPST,
contact NHTSA toll free at
1-888-327-4236 or go to
www.nhtsa.dot.gov. In Canada, contact
Transport Canada toll free at
1-800-333-0371 or go to www.tc.gc.ca
to find a Child Car Seat Clinic in your
area. Failure to properly restrain children
in child restraints made especially for
their height, age and weight, may result
in an increased risk of serious injury or
death to your child.
WARNING:
On hot days, the
temperature inside the vehicle can rise
very quickly. Exposure of people or
animals to these high temperatures for
even a short time can cause death or
serious heat related injuries, including
brain damage. Small children are
particularly at risk.

INSTALLING CHILD
RESTRAINTS
Child Restraints
Use a child restraint (sometimes called an
infant carrier, convertible seat, or toddler
seat) for infants, toddlers, or children
weighing 40 lb (18 kg) or less (generally
age four or younger).
Using Lap and Shoulder Belts WARNING:
Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death. WARNING:
Properly secure
children 12 years old and under in a rear
seating position whenever possible. If
you are unable to properly secure all
children in a rear seating position,
properly secure the largest child on the
front seat. If you must use a forward
facing child restraint on the front seat,
move the seat as far back as possible.
Failure to follow these instructions could
result in personal injury or death. WARNING:
Depending on where
you secure a child restraint, and
depending on the child restraint design,
you may block access to certain seatbelt
buckle assemblies and LATCH lower
anchors, rendering those features
potentially unusable. To avoid risk of
injury, make sure occupants only use
seating positions where they are able to
be properly restrained.
When installing a child restraint with
combination lap and shoulder belts:
• Use the correct seatbelt buckle for that
seating position.
• Insert the belt tongue into the proper
buckle until you hear a snap and feel it
latch. Make sure the tongue is securely
fastened in the buckle.
• Keep the buckle release button
pointing up and away from the child
restraint, with the tongue between the
child restraint and the release button,
to prevent accidental unbuckling.
• Place the vehicle seat upon which the
child restraint will be installed in the
upright position.
• Put the seatbelt in the automatic
locking mode. This vehicle does not
require the use of a locking clip.
Perform the following steps when
installing the child restraint with
combination lap and shoulder belts:
Note: Although the child restraint
illustrated is a forward facing child restraint,
the steps are the same for installing a rear
facing child restraint.

Ranger (TFG) Canada/United States of America, Vehicles Built From: 23-11-2020, MB3J 19A321 AA enUSA, Edition date: 202009, First-Printing Child SafetyE142594

1. Position the child restraint in a seat
with a combination lap and shoulder
belt. 2. Pull down on the shoulder belt and
then grasp the shoulder belt and lap
belt together. 3.
While holding the shoulder and lap belt
portions together, route the tongue
through the child restraint according
to the child restraint manufacturer's
instructions. Make sure the belt
webbing is not twisted. 4. Insert the belt tongue into the proper
buckle (the buckle closest to the
direction the tongue is coming from)
for that seating position until you hear
a snap and feel the latch engage. Make
sure the tongue is latched securely by
pulling on it. 5. To put the retractor in the automatic
locking mode, grasp the shoulder
portion of the belt and pull downward
until you pull all of the seatbelt out.

Note:
The automatic locking mode is
available on the front passenger and rear
seats. This vehicle does not require the use
of a locking clip.
6. Allow the belt to retract to remove slack. The belt clicks as it retracts to
indicate it is in the automatic locking
mode.
7. Try to pull the seatbelt out of the retractor to make sure the retractor is
in the automatic locking mode (you
should not be able to pull more belt
out). If the retractor is not locked,
unbuckle the belt and repeat Steps 5
and 6. 8.
Remove remaining slack from the belt.
Force the seat down with extra weight,
for example, by pressing down or
kneeling on the child restraint as you
pull up on the shoulder belt to force
slack from the belt. This is necessary
to remove the remaining slack that
exists once you add the extra weight
of the child to the child restraint. It also
helps to achieve the proper snugness
of the child restraint to your vehicle.
Sometimes, a slight lean toward the
buckle helps to remove remaining slack
from the belt.
9. Attach the tether strap (if the child restraint is equipped). 10. Before placing the child in the seat,
forcibly move the seat forward and
back to make sure the seat is securely
held in place.
To check this, grab the seat at the belt path
and attempt to move it side to side and
forward and back. There should be no
more than 1 in (2.5 cm) of movement for
proper installation.
We recommend checking with a NHTSA
Certified Child Passenger Safety
Technician to make certain the child
restraint is properly installed. In Canada,
check with Transport Canada for referral
to a Child Car Seat Clinic.
Using Lower Anchors and Tethers
for CHildren (LATCH) WARNING: Do not attach two child
safety restraints to the same anchor. In
a crash, one anchor may not be strong
enough to hold two child safety restraint
attachments and may break, causing
serious injury or death.

Ranger (TFG) Canada/United States of America, Vehicles Built From: 23-11-2020, MB3J 19A321 AA enUSA, Edition date: 202009, First-Printing Child SafetyE142533 E142534

WARNING: Depending on where
you secure a child restraint, and
depending on the child restraint design,
you may block access to certain seatbelt
buckle assemblies and LATCH lower
anchors, rendering those features
potentially unusable. To avoid risk of
injury, make sure occupants only use
seating positions where they are able to
be properly restrained.
The LATCH system is composed of three
vehicle anchor points: two lower anchors
where the vehicle seat backrest and seat
cushion meet (called the seat bight) and
one top tether anchor behind that seating
position.
LATCH compatible child restraints have
two rigid or webbing mounted
attachments that connect to the two lower
anchors at the LATCH equipped seating
positions in your vehicle. This type of
attachment method eliminates the need
to use seatbelts to attach the child
restraint. However, you can still use the
seatbelt to attach the child restraint if the
lower anchors are not used.
For forward-facing child restraints, you
must also attach the top tether strap to
the proper top tether anchor if a top tether
strap has been provided with your child
restraint.
Your vehicle has LATCH lower anchors for
child restraint installation at the following
seating positions. SuperCrew
For SuperCrew vehicles, the lower LATCH
anchors are at the rear section of the rear
seat between the cushion and the seat
backrest.
SuperCab
24
Ranger (TFG) Canada/United States of America, Vehicles Built From: 23-11-2020, MB3J 19A321 AA enUSA, Edition date: 202009, First-Printing Child SafetyE274695 E166695 E281347

For SuperCab vehicles, the lower LATCH
anchors are at the back panel behind the
rear seats.
Follow the child restraint manufacturer's
instructions to properly install a child
restraint with LATCH attachments.
Follow the instructions later in this chapter
on attaching child restraints with tether
straps.
Attach LATCH lower attachments of the
child restraint only to the anchors shown.
Use of Inboard Lower Anchors
from the Outermost Seating
Positions (Center Seating Use)
WARNING: The standardized
spacing for LATCH lower anchors is 11 in
(280 mm) center to center. Do not use
LATCH lower anchors for the center
seating position unless the child restraint
manufacturer's instructions permit and
specify using anchors spaced at least as
far apart as those in this vehicle.
The lower anchors at the center of the
second row rear seat are spaced
25.7 in
(652 mm) apart. The standardized spacing
for LATCH lower anchors is 11.0 in
(280 mm) center to center. You cannot
install a child restraint with rigid LATCH
attachments at the center seating position.
LATCH compatible child restraints (with
attachments on belt webbing) can only be used at this seating position provided that
the child restraint manufacturer's
instructions permit use with the anchor
spacing stated. Do not attach a child
restraint to any lower anchor if an adjacent
child restraint is attached to that anchor.
Each time you use the child restraint, check
that the seat is properly attached to the
lower anchors and tether anchor, if
applicable. Tug the child restraint from side
to side and forward and back where it is
secured to the vehicle. The seat should
move less than
1 in (2.5 cm) when you do
this for a proper installation.
If the child restraint is not anchored
properly, the risk of a child being injured in
a crash greatly increases.
Combining Seatbelt and LATCH
Lower Anchors for Attaching Child
Restraints
When used in combination, either the
seatbelt or the LATCH lower anchors may
be attached first, provided a proper
installation is achieved. Attach the tether
strap afterward, if included with the child
restraint.
Using Tether Straps
Many forward-facing child restraints
include a tether strap which extends from
the back of the child restraint and hooks
to an anchoring point called the top tether
anchor. Tether straps are available as an
accessory for many older child restraints.
Contact the manufacturer of your child
restraint for information about ordering a
tether strap, or to obtain a longer tether
strap if the tether strap on your child
restraint does not reach the appropriate
top tether anchor in the vehicle.
The passenger seats of your vehicle may
have built-in tether strap anchors behind
the seats.
