2012 FORD FUSION HYBRID check engine light

WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulbs work. If any light remains on after starting the vehicle, refer to the
respective system light explanation later in this section for additional
information.
Note:Some warning lights are reconfigurable telltale (RTT) indicators;
they will display in the message center and function the same as the
warning light, but they will not display on startup as regular warning
lights do.
Service engine soon:The service
engine soon light illuminates when
the ignition is turned to the on
position to check the bulb.
•Illuminates with key on, vehicle off:If the light illuminates, the
service engine soon light is working properly.
•Illuminates with key on, vehicle off, then starts to blink:The
light illuminates when the ignition is turned to the on position to
check the bulb and to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. If after 15 seconds the service
engine soon light blinks eight times, it means that the vehicle is not
ready for Inspection/Maintenance (I/M) testing. This can occur if the
vehicle’s engine or transmission has just been serviced, or the battery

has recently run down or been disconnected. If the vehicle does not
need I/M testing, do nothing. The vehicle is designed to check the
emission control system during normal driving. If the vehicle needs
I/M testing, refer to theReadiness for Inspection/Maintenance (I/M)
testingsection in theMaintenance and Specificationschapter.
•Illuminates with engine running:The light stays on after the
engine is started. It indicates that the on board diagnostics system has
detected a problem with the engine, transmission or an
emission-related component or system. Contact your authorized dealer
as soon as possible. The vehicle will usually be drivable and will not
require towing. Refer toOn-board diagnostics (OBD-II)section in
theMaintenance and Specificationschapter for information on
temporary malfunctions that may not require vehicle service.
•Blinks with engine running:The light stays on after the engine is
started and sometimes blinks. It indicates that the On Board
Diagnostics System has detected an engine misfire problem with the
engine. While the light is blinking, engine misfire is occurring which
could damage your catalytic converter. Drive in a moderate fashion
(avoid heavy acceleration and deceleration) and contact your
authorized dealer as soon as possible.
WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.
Brake system warning:To confirm
the brake system warning light is
functional, it will momentarily
illuminate when the ignition is
turned to the on position (when the
engine is not running), or in a position between on and start, or by
applying the parking brake when the ignition is turned to the on
position. If the brake system warning light does not illuminate at this
time, contact your authorized dealer as soon as possible. Illumination
after releasing the parking brake indicates low brake fluid level or brake
system malfunction. Contact your authorized dealer as soon as possible.

Charging system (RTT):
Illuminates when the low-voltage
(12-volt) battery is not charging
properly. The message center
displays CHECK CHARGING SYSTEM. If it stays on while the vehicle is
running (Ready to drive indicator is illuminated), there may be a
malfunction with the charging system. Contact your authorized dealer as
soon as possible. This indicates a problem with the electrical system or a
related component.
Engine oil pressure (RTT):
Illuminates when the oil pressure
falls below the normal range. The
message center displays LOW OIL
PRESSURE when the engine oil level is low. Check the oil level and add
oil if needed. If the warning light or message stays on, even though the
oil level is correct, do not start the engine and contact your authorized
dealer as soon as possible. This indicates a problem with the engine or a
related component. Refer toEngine oilin theMaintenance and
Specificationschapter.
High engine or high motor
electronic coolant temperature
(RTT):Illuminates when the engine
coolant or motor electronics coolant temperature is high. The message
center displays HIGH ENGINE TEMPERATURE / HIGH MOTOR
TEMPERATURE when the engine coolant or motor electronics are
overheating. Stop the vehicle as soon as safely possible, turn off the
engine, and let it cool. Check the coolant and coolant level. If the light
and message stays on or continues to turn on after the vehicle warms
up, contact your authorized dealer as soon as possible. Continuing to
drive with an overheated engine can cause serious engine damage. This
indicates a problem with the engine or a related component. Refer to
Engine coolant and motor/electronics coolantin theMaintenance
and Specificationschapter.

INSTRUMENT PANEL STORAGE COMPARTMENT
The storage compartment may be
used to secure sunglasses or similar
sized objects. Press the button to
open the storage compartment.
AUXILIARY POWER POINT (12V DC)
Power outlets are designed for accessory plugs only. Do not insert
any other object in the power outlet as this will damage the
outlet and blow the fuse. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
Auxiliary power points can be found in the following locations:
•On the instrument panel
•In the center console utility compartment
Do not use the power point for operating the cigarette lighter element (if
equipped).
Note:
Do not plug optional electrical accessories into the cigarette lighter
socket (if equipped). Improper use of the lighter can cause damage not
covered by your warranty, and can result in fire or serious injury.
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 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.

factory installed block heater system does not have a thermostat;
however, maximum temperature is attained after approximately three
hours of operation. Block heater operation longer than three hours will
not improve system performance and will unnecessarily use additional
electricity.
Make sure system is unplugged and properly stowed before driving the
vehicle. While not in use, make sure the protective cover seals the
prongs of the engine block heater cord plug.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.
Refer toWarning lights and
chimesin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an anti-lock braking system (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. The ABS operates by detecting the
onset of wheel lockup during brake application and compensates for this
tendency. Noise from the ABS pump motor and brake pedal pulsation
may be observed during ABS braking; any pulsation or mechanical noise
you may feel or hear is normal. In addition, the ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.

The AdvanceTracsystem includes
a stability control switch on the
instrument panel, a stability control
light and a stability control off light
in the instrument cluster. Both the stability control light and the stability
control off light in the instrument cluster will illuminate temporarily
during start-up as part of a normal system self-check. The stability
control light may illuminate (flash) during certain driving situations
which cause the AdvanceTracsystem to operate. If the stability control
light illuminates steadily, have the system serviced by an authorized
dealer immediately. If equipped with a message center, the vehicle will
also indicate a failure with the AdvanceTracsystem.
Note:If the system cannot be turned off, refer toMyKeyin theLocks
and Securitychapter for more information.
When AdvanceTracperforms a normal system self-check, some drivers
may notice a slight movement of the brake, and/or a rumble, grunting, or
grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTracyou may experience
the following:
•A slight deceleration of the vehicle
•The stability control light will flash.
•If your foot is on the brake pedal, a vibration in the pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.
Traction control system (TCS)
Traction control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem; engine traction control and brake traction
control. Engine traction control works to limit drive-wheel spin by
momentarily reducing engine power. Brake traction control works to limit
wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction control is most active at low speeds.
During TCS events, the stability control light in the instrument cluster
will flash.

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 SERVICE POWER STEERING, SERVICE
POWER STEERING NOW or POWER STEERING ASSIST FAULT may
display in the message center, refer to theMessage centerin theDriver
Controlschapter for more information.

fill inlet lamp or CHECK FUEL FILL INLET message may not reset
immediately. It may take several driving cycles for the check fuel fill inlet
lamp or CHECK FUEL FILL INLET message to turn off. A driving cycle
consists of an engine start-up (after four or more hours with the engine
off) followed by city/highway driving. Continuing to drive with the check
fuel fill inlet lamp or CHECK FUEL FILL INLET message on may cause
the service engine soon lamp to turn on as well.
WARNING:The fuel system may be under pressure. If you hear
a hissing sound near the fuel filler door (Easy Fuel“no cap”
fuel system), do not refuel until the sound stops. Otherwise, fuel may
spray out, which could cause serious personal injury.
Choosing the right fuel
Use only UNLEADED fuel or UNLEADED fuel blended with a maximum
of 10% ethanol. Do not use fuel ethanol (E85), diesel, methanol, leaded
fuel or any other fuel. The use of leaded fuel is prohibited by law and
could damage your vehicle.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives.
Note:Use of any fuel other than those recommended may cause
powertrain damage, a loss of vehicle performance, and repairs may not
be covered under warranty.
Octane recommendations
“Regular” unleaded gasoline with a
pump (R+M)/2 octane rating of 87 is
recommended. Some stations offer
fuels posted as “Regular” with an
octane rating below 87, particularly
in high altitude areas. Fuels with octane levels below 87 are not
recommended.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of “Regular” unleaded
gasoline.
