Passenger Compartment Fuse Box WARNING: Always disconnect the
battery before servicing high current
fuses.
Note: If your vehicle has dual batteries,
disconnecting the primary under hood
battery does not remove power from all
circuits. The fuse panel is to the left-hand side of
the brake pedal and mounted onto the
lower left-hand cowl panel. Remove the
fuse panel cover to access the fuses.
To remove a fuse, use the fuse puller tool
provided on the inside of the fuse panel
cover.
Replace fuses with the same type and
rating. See
Changing a Fuse (page 159).

When this occurs, your vehicle still
operates, however:
•
Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated WARNING: Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly. Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Engine Coolant Temperature
Management
(If Equipped) WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the
vehicle may not be able to accelerate
with full power until the coolant
temperature reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long
or steep slope in high ambient
temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.

E-Series (TE4) Canada/United States of America, enUSA, Edition date: 201910, First-Printing Maintenance

Note:
The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
Note: Do not use wheels or lug nuts
different than the original equipment, as this
may damage the wheel or mounting system.
If you get a flat tire when driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
Have a flat serviced by an authorized
dealer in order to prevent damage to the
tire pressure monitoring system sensors.
See Tire Pressure Monitoring System
(page 208). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the tire
pressure monitoring system sensor for
damage.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided
by Ford. If the dissimilar spare tire or wheel
is damaged, it should be replaced rather
than repaired. A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and wheels
and can be one of three types:
1.
T-type mini-spare:
This spare tire
begins with the letter T for tire size and
may have Temporary Use Only molded in
the sidewall.
2. Full-size dissimilar spare with label
on wheel:
This spare tire has a label on
the wheel that states: THIS WHEEL AND
TIRE ASSEMBLY FOR TEMPORARY USE
ONLY.
When driving with one of the dissimilar
spare tires listed above, do not:
• Exceed
50 mph (80 km/h).
• Load the vehicle beyond maximum
vehicle load rating listed on the Safety
Compliance Label.
• Tow a trailer.
• Use snow chains on the end of the
vehicle with the dissimilar spare tire.
• Use more than one dissimilar spare tire
at a time.
• Use commercial car washing
equipment.
• Try to repair the dissimilar spare tire.
Use of one of the dissimilar spare tires
listed above at any one wheel location can
lead to impairment of the following:
• Handling, stability and braking
performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability.
• Wet weather driving capability.
• All-wheel driving capability.
3. Full-size dissimilar spare without
label on wheel
214
E-Series (TE4) Canada/United States of America, enUSA, Edition date: 201910, First-Printing Wheels and Tires

When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•
Exceed 70 mph (113 km/h).
• Use more than one dissimilar spare
wheel and tire assembly at a time.
• Use commercial car washing
equipment.
• Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly.
The usage of a full-size dissimilar spare
wheel and tire assembly can lead to
impairment of the following:
• Handling, stability and braking
performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability.
• Wet weather driving capability.
• All-wheel driving capability.
When driving with the full-size dissimilar
spare wheel and tire assembly additional
caution should be given to:
• Towing a trailer.
• Driving vehicles equipped with a
camper body.
• Driving vehicles with a load on the
cargo rack.
Drive cautiously when using a full-size
dissimilar spare wheel and tire assembly
and seek service as soon as possible.
Tire Change Procedure WARNING:
When one of the front
wheels is off the ground, the
transmission alone will not prevent the
vehicle from moving or slipping off the
jack, even if the transmission is in park
(P). WARNING:
To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park
(P), set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel,
place an appropriate block or wheel
chock on the right rear wheel. WARNING:
Do not get under a
vehicle that is only supported by a
vehicle jack. WARNING:
Do not attempt to
change a tire on the side of the vehicle
close to moving traffic. Pull far enough
off the road to avoid the danger of being
hit when operating the jack or changing
the wheel. WARNING:
Always use the jack
provided as original equipment with your
vehicle. If using a jack other than the one
provided, make sure the jack capacity is
adequate for the vehicle weight,
including any vehicle cargo or
modifications. If you are unsure if the jack
capacity is adequate, contact the
authorized dealer.
Note: Passengers should not remain in your
vehicle when the vehicle is being jacked.
Removing the flat wheel and tire
1. Park on a level surface, set the parking
brake and activate the hazard flashers.
2. Place the transmission in park (P) and
turn the engine off.
