wiring FORD EXPLORER 2021 Owners Manual

This system provides an improved overall
level of frontal crash protection to front
seat occupants and is designed to help
further reduce the risk of airbag-related
injuries. The system analyzes different
occupant conditions and crash severity
before activating the appropriate safety
devices to help better protect occupants
in a variety of frontal crash situations.
Your vehicle's Personal Safety System
consists of:
•
Driver and passenger dual-stage airbag
supplemental restraints.
• Front seat outermost seatbelts with
pretensioners, energy management
retractors and seatbelt usage sensors.
• Front passenger sensing system.
• Passenger airbag off and on indicators.
• Front crash severity sensors.
• Restraints control module with impact
and safing sensors.
• Restraint system warning light and
tone.
• The electrical wiring for the airbags,
crash sensors, seatbelt pretensioners,
front seatbelt usage sensors, front
passenger sensing system and
indicator lights.
How Does the Personal Safety
System Work?
The Personal Safety System can adapt the
deployment strategy of the safety devices
according to crash severity and occupant
conditions. A collection of crash and
occupant sensors provides information to
the restraints control module. During a
crash, the restraints control module may
deploy the seatbelt pretensioners, one or
both stages of the dual-stage airbags
based on crash severity and occupant
conditions.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the proper
installation and adjustment
specifications.
• Service your vehicle more frequently if
you tow a trailer.
See Scheduled
Maintenance (page 482).
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
You can find information on load
specification terms found on the tire label
and Safety Compliance label as well as
instructions on calculating your vehicle's
load in the Load Carrying chapter.
See
Load Limit (page 282).
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle.
Distribute the trailer load so 10-15% of the
total trailer weight is on the tongue.
A weight distributing hitch is not required
for your vehicle.
Safety Chains
Note: Do not attach safety chains to the
bumper.
Always connect the safety chains to the
hook retainers of your vehicle hitch. To connect the trailer
’s safety chains, cross
them under the trailer tongue and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground.
Trailer Brakes WARNING:
Do not connect a
trailer's hydraulic brake system directly
to your vehicle's brake system. Your
vehicle may not have enough braking
power and your chances of having a
collision greatly increase.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Safe control of towed vehicles requires
separate functioning brake systems for
vehicles and trailers weighing more than
1,500 lb (680 kg)
when loaded.
Trailer Lamps WARNING:
Never connect any
trailer lamp wiring to the vehicle's tail
lamp wiring; this may damage the
electrical system resulting in fire. Contact
your authorized dealer as soon as
possible for assistance in proper trailer
tow wiring installation. Additional
electrical equipment may be required.
Most towed vehicles require trailer lamps.
Make sure all running lights, brake lights,
direction indicators and hazard flashers
are working.

Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow. 2. Set your vehicle parking brake.
3. Place the automatic transmission in
park (P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
