2021 FORD MUSTANG ECO mode

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 in the upright
position before you install the child
restraint.
• Put the seatbelt in the automatic
locking mode. See Step 5. 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. 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. 29

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 that you have
not twisted the belt webbing. 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 all of the belt is pulled 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 will click as it retracts
to indicate it is in the automatic locking
mode.
7. Try to pull the belt 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 does not lock, 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 while
pulling up on the shoulder belt in order
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 will additionally help
to remove remaining slack from the
belt.
9. If the child restraint has a tether strap, attach it.

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 and
have vehicle sensitive locking mode. In
addition, the front outboard passenger and
rear seat seatbelts have the automatic
locking mode.
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
or 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 a child safety seat,
except a booster, is installed in passenger
front or rear seating positions. Properly
restrain children 12 years old and under in
a rear seating position whenever possible.
See
Child Safety (page 25).
How to Disengage the Automatic
Locking Mode
Unbuckle the combination lap and
shoulder belt and allow it to retract
completely to disengage the automatic
locking mode and activate the vehicle
sensitive (emergency) locking mode.
SEATBELT WARNING LAMP
AND INDICATOR CHIME This lamp illuminates and an
indicator chime will sound if the
driver seatbelt has not been
fastened when the vehicle's ignition is

seatbelt three times at a moderate
speed, ending in the unbuckled state.
After Step 3, the seatbelt warning lamp
turns on.

CHILD RESTRAINT AND
SEATBELT MAINTENANCE
Inspect the vehicle seatbelts and child
safety seat systems periodically to make
sure they work properly and are not
damaged. Inspect the vehicle and child
restraint seatbelts to make sure there are
no nicks, tears or cuts. Replace if
necessary. All vehicle seatbelt assemblies,
including retractors, buckles, front seatbelt
buckle assemblies, buckle support
assemblies (slide bar-if equipped),
shoulder belt height adjusters (if
equipped), shoulder belt guide on seat
backrest (if equipped), child safety seat
LATCH and tether anchors, and attaching
hardware, should be inspected after a
crash. Read the child restraint
manufacturer's instructions for additional
inspection and maintenance information
specific to the child restraint.
We recommend that all seatbelt
assemblies in use in vehicles involved in a
crash be replaced. However, if the crash
was minor and an authorized dealer finds
that the belts do not show damage and
continue to operate properly, they do not
need to be replaced. Seatbelt assemblies
not in use during a crash should also be
inspected and replaced if either damage
or improper operation is noted.
Properly care for seatbelts. See Vehicle
Care (page 289).
SEATBELT EXTENSIONS WARNING:
Persons who fit into
the vehicle's seatbelt should not use an
extension. Unnecessary use could result
in serious personal injury in the event of
a crash. WARNING:
Only use extensions
provided free of charge by our dealers.
The dealer will provide an extension
designed specifically for this vehicle,
model year and seating position. The use
of an extension intended for another
vehicle, model year or seating position
may not offer you the full protection of
your vehicle's seatbelt restraint system. WARNING:
Never use seatbelt
extensions to install child restraints. WARNING:
Do not use a seatbelt
extension with an inflatable seatbelt. WARNING:
Do not use extensions
to change the way the seatbelt fits
across the torso, over the lap or to make
the seatbelt buckle easier to reach.
If, because of body size or driving position,
it is not possible to properly fasten the
seatbelt over your lap and shoulder, an
extension that is compatible with the
seatbelts is available free of charge from
our dealers. Only use our seatbelt
extensions made by the original equipment
seatbelt manufacturer with our seatbelts.
Ask your authorized dealer if your extension
is compatible with your vehicle restraint
system.
