To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12V DC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer toFuses and
relaysin theRoadside Emergencieschapter for information on
checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
•do not use the power point longer than necessary when the engine is
not running,
•do not leave battery chargers, video game adapters, computers and
other devices plugged in overnight or when the vehicle is parked for
extended periods.
Always keep the power point caps closed when not being used.
POWER WINDOWS (IF EQUIPPED)
WARNING:Do not leave children unattended in the vehicle and
do not let children play with the power windows. They may
seriously injure themselves.
WARNING:When closing the power windows, you should verify
they are free of obstructions and ensure that children and/or
pets are not in the proximity of the window openings.
Press and pull the window switches
to open and close windows.
•Press down (to the first detent)
and hold the switch to open.
•Pull up (to the first detent) and
hold the switch to close.
Rear Window Buffeting:When one or both of the rear windows are
open, the vehicle may demonstrate a wind throb or buffeting noise. This
noise can be alleviated by lowering a front window approximately
2–3 inches (5–8 cm).

may display in the multifunction display. Refer to theMessage centerin
theInstrument Clusterchapter 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 POWER
STEERING ASSIST FAULT 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 POWER STEERING ASSIST FAULT.
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.
If the steering wanders or pulls, check for:
•an improperly inflated tire.
•uneven tire wear.
•loose or worn suspension components.
•loose or worn steering components.
•improper steering alignment.
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
Speed sensitive steering
The steering in your vehicle is speed sensitive. At lower speeds the assist
is increased to improve maneuverability.
If the amount of effort required to steer your vehicle changes while
driving at a constant vehicle speed, have the power steering system
checked by your authorized dealer.
BRAKE-SHIFT INTERLOCK
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the on position unless the brake pedal is pressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the on position and the brake pedal pressed, it is possible that a fuse has
blown or the vehicle’s brake lamps are not operating properly. Refer to
Fuses and relaysin theRoadside Emergencieschapter.

FUEL PUMP SHUT-OFF
In the event of a moderate to severe collision, this vehicle is equipped
with a fuel pump shut-off feature that stops the flow of fuel to the
engine. Not every impact will cause a shut-off.
Should your vehicle shut off after a collision due to this feature, you may
restart your vehicle by doing the following:
1. Turn the ignition switch to the off position.
2. Turn the ignition switch to the on position.
In some instances the vehicle may not restart the first time you try to
restart and may take one additional attempt.
WARNING:Failure to inspect and if necessary repair fuel leaks
after a collision may increase the risk of fire and serious injury.
Ford Motor Company recommends that the fuel system be inspected
by an authorized dealer after any collision.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle’s main electrical systems from overloads.
WARNING:Always disconnect the battery before servicing high
current fuses.
WARNING:To reduce risk of electrical shock, always replace
the cover to the power distribution box before reconnecting the
battery or refilling fluid reservoirs.
