MAXIMIZING YOUR DRIVING
RANGE
Driving in Cold Weather
Keep your vehicle charged before heading
out into cold weather.
Use the heated seats and steering wheel
for comfort along with moderate cabin
temperature and fan settings to reduce
energy needed for climate control.
Preconditioning Your Vehicle
You can precondition your vehicle by using
departure and comfort settings to warm
or cool your cabin and the high voltage
battery when your vehicle is plugged in. By
using energy from your charging source
prior to your departure, battery
temperature can be managed for best
driving performance and less energy will
be needed for heating or cooling of the
cabin at the start of your drive. This helps
maximize your driving range. See Setting
the Charging Schedule and Preferences
(page 174).
Note: You can also access departure and
comfort settings using the FordPass App.
Note: Lower cabin temperature settings on
the climate control system results in better
trip range.
Parking Your Vehicle
At temperatures just above the freezing
point and lower, plug your vehicle in when
not in use to maintain high voltage battery
performance.
When possible park your vehicle under a
covered area or in a garage. This will help
to moderate temperatures which affect
performance of the high voltage battery
and require energy to heat or cool the
cabin. Driving Style
Range is reduced when driving aggressively
or at consistently high speeds. Aggressive
driving for extended periods could also
result in reducing your battery
’s efficiency
and lifespan. Use the trip application on
your touchscreen to see your driving scores.
See
Trip Data (page 124).
DRIVING THROUGH SHALLOW
WATER WARNING:
Do not attempt to
cross a deep or flowing body of water.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death.
Note: Driving through standing water can
cause vehicle damage.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the front
rocker area of your vehicle. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction could
be limited. After driving through water and
as soon as it is safe to do so:
