2008 Mercury Mariner 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 warning light for additional information.
Check engine:TheCheck Engine
indicator light illuminates when the
ignition is first turned to the RUN
position to check the bulb and to
indicate whether the vehicle is ready for Inspection/Maintenance (I/M)
testing. Normally, the
Check Engine
light will stay on until the engine is
cranked, then turn itself off if no malfunctions are present. However, if
after 15 seconds the
Check Engine
light blinks eight times, it means
that the vehicle is not ready for I/M testing. See theReadiness for
Inspection/Maintenance (I/M) testingin theMaintenance and
Specificationschapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If 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 have your vehicle serviced
immediately by your authorized dealer.

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.
Check fuel cap:Illuminates when
the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Check
engine warning light to come on,
refer toFuel filler capin the
Maintenance and Specificationchapter.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the RUN
position (when the engine is not running), or in a position between RUN
and START, or by applying the parking brake when the ignition is turned
to the RUN position. If the brake system warning light does not
illuminate at this time, seek service immediately from your authorized
dealer. Illumination after releasing the parking brake indicates low brake
fluid level and the brake system should be inspected immediately by
your authorized dealer.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your authorized dealer. Driving extended distances with
the parking brake engaged can cause brake failure and the risk of
personal injury.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.

Engine or motor electronic
coolant temperature:Illuminates
when the coolant temperature
exceeds the threshold. When the light is flashing or remains on, stop the
vehicle as soon as possible, switch off the engine and let cool. Refer to
Engine coolant and motor/electronics coolantin theMaintenance
and Specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot.
ABS active/Traction control
active (if equipped):Flashes
when the ABS system is active. If
the light remains on, have the
system serviced immediately, refer
to theDrivingchapter for more
information.
Low tire pressure warning:
Illuminates when your tire pressure
is low. If the light remains ON at
start up or while driving, the tire
pressure should be checked. Refer
toInspecting and Inflating Your Tiresin theTires, Wheels and
Loadingchapter. When the ignition is first turned to RUN, the light will
illuminate for 3 seconds to ensure the bulb is working. If the light does
not turn ON or begins to flash, have the system inspected by your
authorized dealer. For more information on this system, refer to
Understanding Your Tire Pressure Monitoring Systemin theTires,
Wheels and Loadingchapter.
Low fuel:Illuminates when the fuel
level in the fuel tank is at or near
empty (refer toFuel gaugein this
chapter).

The auxiliary power point is located
in the instrument panel.
A second auxiliary power point is
located on the rear side of the
center console.
Do not use the power point for
operating the cigarette lighter
element (if equipped).
To prevent the fuse from being
blown, do not use the power
point(s) over the vehicle capacity of 12 VDC/180W. If the power point or
cigar lighter socket is not working, a fuse may have blown. Refer to
Fuses and Relaysin theRoadside Emergencieschapter for information
on checking and replacing fuses.
To prevent the battery from being discharged, do not use the power
point longer than necessary when the engine is not running.
Always keep the power point caps closed when not being used.
Cigar/Cigarette lighter (if equipped)
Do not plug optional electrical accessories into the cigarette lighter
socket.
Do not hold the lighter in with your hand while it is heating, this will
damage the lighter element and socket. The lighter will be released from
its heating position when it is ready to be used.
Improper use of the lighter can cause damage not covered by your
warranty.
Power point (110 VAC) (if equipped)
The 110 VAC power point outlet is used for powering electrical devices
that require up to 150W. Exceeding the 150W limit will cause the power
point to cut off the power temporarily to provide overload protection.

•Do not use alcohol, methanol, brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol
and other liquids can cause engine damage from overheating or
freezing.
•Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the “FULL COLD” level. For all other vehicles which have a
coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.
To reduce the risk of personal injury, make sure the engine is
cool before unscrewing the coolant pressure relief cap. The
cooling system is under pressure; steam and hot liquid can come out
forcefully when the cap is loosened slightly.
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the “COLD FILL RANGE” or the “FULL COLD” level on
the reservoir. If you removed the radiator cap in an overflow system, fill
the radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. Cap must be tightly
installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration (refer
toChecking engine coolant). If the concentration is not 50/50
(protection to –34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.

If you have run out of fuel:
•You may need to cycle the ignition from OFF to ON several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.
•Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than 1
gallon (3.8L) may be required.
•The
indicator may come on. For more information on the “check
engine” or the “service engine soon” indicator, refer toWarning lights
and chimesin theInstrument Clusterchapter.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend taking
fuel economy measurements during the first 1,000 miles (1,600 km) of
driving (engine break-in period). You will get a more accurate
measurement after 2,000 miles–3,000 miles (3,000 km–5,000 km).
Filling the tank
When the fuel gauge indicates empty, there is still a small reserve of fuel
in the fuel system. When refueling your vehicle after the fuel gauge
indicates empty, you might not be able to refuel the full amount of the
advertised capacity of the fuel tank due to the empty reserve still
present in the tank. The amount of usable fuel in the empty reserve
varies and should not be relied upon to increase driving range.
For consistent results when filling the fuel tank:
•Turn the engine/ignition switch to the off position prior to refueling;
an error in the reading will result if the engine is left running.
•Allow no more than two automatic click-offs when filling.
•Always use fuel with the recommended octane rating.
•Use a known quality gasoline, preferably a national brand.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial odometer reading
(in miles or kilometers).

•Minimize temperature extremes when the vehicle is parked, for
example by storing in a garage to avoid extreme cold in winter and
extreme sun loads in summer. The high voltage battery operates more
efficiently in moderate temperatures.
•Combine errands. Your vehicle is more fuel efficient when the engine
is warm. Driving to your farthest destination first will warm the engine
more quickly and may improve fuel economy for the rest of the trip.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Keep wheels properly aligned.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 300 lb [136 kg] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks, flags)
may reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Driving on flat terrain offers improved fuel economy as compared to
driving on mountainous terrain.
•Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
authorized dealer if the window sticker is not supplied with your vehicle.
The EPA window sticker should be your guide for the fuel economy
comparisons with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of MPG (L/100 km)
expected on the vehicle under optimum conditions. Your fuel economy
may vary depending upon the method of operation and conditions.
