Switching off traction control
If the vehicle is stuck in snow, mud or sand, and seems to lose power,
switching off the traction control feature of the AdvanceTracsystem
may be beneficial because the wheels are allowed to spin. This will
restore full power and will enhance momentum through the obstacle.
The traction control system can be turned off through the message
center. See Message center in theInstrument Cluster chapter for more
information. If you switch off the traction control, the stability control off
light will illuminate steadily. Selecting traction control on will turn off the
stability control off light.
Steering
Your vehicle is equipped with an Electric Power Steering (EPS) system.
There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Under extreme usage conditions, the steering effort may
increase. This occurs to prevent overheating and permanent damage to
your steering system. If this should occur, you will neither lose the ability
to steer the vehicle manually nor will it cause permanent damage.
Typical steering and driving maneuvers will allow the system to cool and
steering assist will return to normal.
The EPS system has diagnostic checks that continuously monitor the
EPS system to ensure proper operation. When a system error is
detected, the following message STEERING ASSIST FAULT SERVICE
REQUIRED, STEERING FAULT SERVICE NOW, STEERING LOSS STOP
SAFELY may display in the multifunction display. Refer to the Message
center in theInstrument Cluster chapter for more information.
WARNING:The EPS has diagnostics checks that continuously
monitor the EPS to ensure proper operation of the electronic
system. When an electronic error is detected, the message STEERING
ASSIST FAULT SERVICE REQUIRED will be displayed in the message
center. If this happens, stop the vehicle in a safe place and turn off the
engine. After at least 10 seconds, reset the system by restarting the engine,
and watch the message center for STEERING ASSIST FAULT SERVICE
REQUIRED. If the message returns, or returns while driving, take the
vehicle to your dealer to have it checked. With the message displayed, the
steering assist is turned off, making the vehicle harder to steer.

Note:Electrical or electronic accessories or components added to the
vehicle by the dealer or the owner may adversely affect battery
performance and durability and may also affect the performance of other
electrical systems in the vehicle.
When a battery replacement is required, the battery should only be
replaced with a Ford recommended replacement battery that matches
the electrical requirements of the vehicle.
Note: The clock and the preset radio stations must be reset once the
battery is reconnected.
•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
HIGH-VOLTAGE BATTERY
WARNING: This battery pack should only be serviced by an
authorized electric vehicle technician. Improper handling can
result in personal injury or death.
Your vehicle consists of various high-voltage components and wiring. All
of the high-voltage power flows through specific wiring assemblies which
are labeled as such and/or are covered with a solid orange convolute or
orange striped tape. Do not come in contact with these components.
No regular maintenance, other than regular charging is required.
The high-voltage battery system is a high-voltage, lightweight lithium-ion
battery system comprised of two individual packs. One pack is located in
the rear cargo area behind the second row seats, and the other is located
underneath the vehicle. The high-voltage battery system uses an advanced,
active liquid heating and cooling system to regulate high-voltage battery
temperature and help maximize high-voltage battery life.

Note:The vehicle must be in (P) park to charge the high-voltage battery.
Make sure that the 120 volt
convenience cord is completely
unwound before charging. Always
plug the cord into the AC outlet
before connecting the charging
coupler into the vehicle’s charge
port receptacle. The 120 volt
convenience cord inline control box
has three indicator lights that
represent the charging status;
power, charge and fault.
The charge port is located between the front left side door and front left
wheel well. There is an indentation located on the charge port door that
allows you to press to open and press to close the door.
Power (green light) — this indicator lights up when the cord is plugged
into the AC wall outlet.
Charge (green light) — Indicates status of charging:
• No light means the cord is not connected to the vehicle.
• Blinking light means that the charging is in process.
• Solid light means that the vehicle is connected but not charging.
Fault (red triangle light) — Lights up in case of a detected failure. No
charging is possible:
• Blinking red triangle light – means that the 120 volt convenience cord
is trying to reset the failure and could restart the charging cycle.
• Solid red triangle light – means that the fault is permanent. The cord
needs to be unplugged and re-plugged to reset the fault. If the fault
persists, contact your authorized dealer.

LOW AND HIGH VOLTAGE BATTERY STORAGE
If your vehicle is to be stored for 30 days or longer, the high voltage
battery should be charged to above 25% state of charge and the low
voltage (under hood) battery negative terminal should be disconnected.
If your vehicle is to be stored for 3 months or longer, the high voltage
battery should be charged to between 80% and 100% state of charge and
the low voltage (under hood) battery negative terminal should be
disconnected. Failure to do this could damage the batteries.
Note:If battery cables are disconnected, it will be necessary to reset
memory features.
