AWD Temporarily
Disabled
The all wheel drive system is locking up the torque transfer clutchto help reduce clutch temperature.
AWD Temporarily
Locked
Displays when the system automatically disables to protect itself.
This may be caused by operating the vehicle with a mini spare tire installed, if the system detects dissimilar size tires, or if there is an
issue with another vehicle system preventing AWD operation. The system resumes normal operation and clears this message after
you cycle the ignition on and off and drive a short distance with the road tire re-installed or after the other vehicle system issues are resolved.
AWD OFF
Displays after the system cools and the all wheel drive system resumes normal function.

Braking
Your hybrid vehicle has standard hydraulic
braking and regenerative braking. The
transmission performs regenerative
braking. It captures brake energy and
stores it in the high voltage battery. The
transmission changes gears while
decelerating and captures the maximum
energy back into the high voltage battery.
Driving to Optimize Fuel Economy
Your fuel economy should improve
throughout the hybrid vehicle break-in
period. As with any vehicle, your driving
habits and accessory usage can
significantly impact your fuel economy. For
best results, keep these tips in mind:
•
Properly inflate the recommended size
tires.
• Aggressive driving increases the
amount of energy your vehicle requires
to move. In general, you can achieve
better fuel economy with mild to
moderate acceleration and
deceleration. Moderate braking is
particularly important since it allows
you to maximize the energy the
regenerative braking system captures.
Additional tips:
• Do not carry extra loads.
• Be mindful of adding external
accessories that could increase
aerodynamic drag.
• Observe posted speed limits.
• Perform all scheduled maintenance.
• There is no need to wait for the engine
to warm up. Your vehicle is
immediately ready to drive after
starting.
Note: Having the engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode.

automatically disabled to protect itself.
This is caused by operating the vehicle with the compact spare tire installed or if thesystem is overheating. The system willresume normal function and clear this
message after cycling the ignition on and off and driving a short distance with the
road tire re-installed or after the system is allowed to cool.
AWD OFF
Displayed when the all wheel drive systemresumes normal function and clears this
message after driving a short distance with
the road tire re-installed or after the system cools.
AWD Restored
Displayed when the all wheel drive system
has automatically disabled itself due to thesystem overheating.
AWD Temporarily Disabled
Displayed when the all wheel drive systemneeds to temporarily lock to help reduce the heat in the AWD torque actuator.
AWD Temporarily Locked
Displayed in conjunction with the power-train malfunction/reduced power light
when the system is not operating properly. If the warning stays on or continues to
come on, contact your authorized dealer as soon as possible.
AWD Malfunction Service Required
Never use a spare tire of a different size
other than the tire provided. The AWD
system will disable and enter rear-wheel
drive only mode to protect driveline
components if a non-full sized tire is
installed. Some limited AWD traction could
be provided if a mini-spare is installed on
one of the front wheels. If you are in driving
conditions where limited AWD traction is
needed while a mini-spare is installed, it is
recommended the mini-spare be installed
on the front axle. If a mini-spare is installed, this condition is
indicated by a message in the information
display. If there is a message in the
information display from using a non-full
sized spare tire, this indicator should turn
off after reinstalling the repaired or
replaced normal road tire and cycling the
ignition off and on. It is recommended to
145
Explorer (CTW) Police, Canada/United States of America, Police, enUSA, Edition date: 202007, Second-Printing All-Wheel Drive

reinstall the repaired or replaced road tire
as soon as possible. Major dissimilar tire
sizes between the front and rear axles
could cause the AWD system to stop
functioning and default to rear-wheel drive
or damage the AWD system.
Operating AWD Vehicles With
Mismatched Tires
WARNING: Only use replacement
tires and wheels that are the same size,
load index, speed rating and type (such
as P-metric versus LT-metric or
all-season versus all-terrain) as those
originally provided by Ford. The
recommended tire and wheel size may
be found on either the Safety
Compliance Certification Label (affixed
to either the door hinge pillar, door-latch
post, or the door edge that meets the
door-latch post, next to the driver's
seating position), or the Tire Label which
is located on the B-Pillar or edge of the
driver's door. If this information is not
found on these labels, then you should
contact your authorized dealer as soon
as possible. Use of any tire or wheel not
recommended by Ford can affect the
safety and performance of your vehicle,
which could result in an increased risk of
loss of vehicle control, vehicle rollover,
personal injury and death.
Major dissimilar tire sizes between the front
and rear axles (for example, 17 inch low
profile tires on the front axle and 22 inch
high profile tires on the rear axle) could
cause the AWD system to stop functioning
and default to rear-wheel drive or damage
the AWD system. For optimum AWD
Performance, it is recommended to follow
the tire rotation maintenance schedule. To
avoid potential AWD malfunction or AWD
system damage, it is recommended to
replace all four tires rather than mixing significantly worn tires with new tires. For
example, using 3 worn tread tires and 1 new
tread tire all of the same original tire
size/brand and can be tolerated by the
AWD system as long as the worn tires still
have usable tread depth.
How Utility Vehicles Differ from
Other Vehicles
Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough
terrain without getting hung up or
damaging underbody components.
The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
Maintain steering wheel control at all
times, especially in rough terrain. Since
sudden changes in terrain can result in
abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the
area. To maintain steering and braking
control of your vehicle, you must have all
four wheels on the ground and they must
be rolling, not sliding or spinning.
Driving In Special Conditions With
All-Wheel Drive (AWD)
Note:
Use of AWD in slippery, deep snow,
and sand drive modes on dry surfaces could
produce some vibration and driveline bind
up, and or excessive tire wear as these drive
modes are intended for slippery and loose
surfaces.

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It’ s always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator ’s ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system automatically turns on each
time you switch the ignition on. If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the system applies
higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.

REDUCED ENGINE
PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See Gauges
(page 78).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See
Engine
Coolant Check (page 226).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle. You may improve your fuel economy by
keeping these things in mind:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at
55 mph (88 km/h) uses 15% less
fuel than traveling at 65 mph
(105 km/h)).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before switching it
off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.
• Drive a heavily loaded vehicle or tow a
trailer.

GENERAL INFORMATION
Use only approved wheel and tire sizes,
using other sizes could damage your
vehicle. If you change the diameter of the
tires from that fitted at the factory, the
speedometer may not display the correct
speed, and the All Wheel Drive (AWD)
system may not function properly. Take
your vehicle to an authorized dealer to
have the system reprogrammed. If you
intend to change the size of the wheels
from that fitted by the manufacturer, you
can check the suitability with an authorized
dealer.
Additional information related to the
functionality and maintenance of your tires
can be found later in this chapter. See Tire
Care (page 247).
The recommended tire inflation pressures
can be found on the Tire Label, which is
located on the B-pillar or the edge of the
driver's door. This information can also be
found on the Safety Compliance
Certification Label, affixed to either the
door hinge pillar, door-latch post, or the
door edge that meets the door latch post;
next to the driver ’s seating position.
We strongly recommend maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the
way your vehicle handles.
Note: Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note: Check your tire pressures at least
once per month.
Set the pressure for your spare tire to the
highest value given for your vehicle and tire
size combination, if equipped. Notice to utility vehicle and truck
owners WARNING:
Utility vehicles have a
significantly higher rollover rate than
other types of vehicles. WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
seatbelt. WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Utility vehicles and trucks handle
differently than passenger cars in the
various driving conditions that are
encountered on streets, highways and
off-road. Utility vehicles and trucks are not
designed for cornering at speeds as high
as passenger cars any more than low-slung
sports cars are designed to perform
satisfactorily under off-road conditions.
