2015 FORD EXPLORER check engine light

Brake system warning light
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 it illuminates when you are driving, check that the parking brake is not
engaged. If the parking brake is not engaged, this indicates low brake
fluid level or a brake system malfunction. Have the system checked
immediately by your authorized dealer.
WARNING: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 as soon as possible.
Driving extended distances with the parking brake engaged can cause
brake failure and the risk of personal injury.
Charging system (RTT)
Illuminates when the battery is not charging properly. If it stays
on while the engine is running, 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.
Door ajar (RTT)
Displays when the ignition is on and any door is not completely
closed.
Engine oil pressure (RTT)
Illuminates when the oil pressure falls below the normal range.
Engine coolant temperature (RTT)
Illuminates when the engine coolant temperature is high. Stop
the vehicle as soon as possible, switch off the engine and let
cool.

Low washer fluid (RTT)
Illuminates when the windshield washer fluid is low.
Parking Lamps (RTT)
It will illuminate when you switch the parking lamps on.
Powertrain malfunction/reduced power
Illuminates when a powertrain or an 4WD fault has been
detected. Contact your authorized dealer as soon as possible.
Safety belt
Reminds you to fasten your safety belt. A Belt-Minder® chime
will also sound to remind you to fasten your safety belt.
Service engine soon
Theservice engine soonindicator light illuminates when the
ignition is first turned to the on position to check the bulb and to
indicate whether the vehicle is ready for Inspection/Maintenance
(I/M) testing. Normally, the “service engine soon” light will stay on until the
engine is cranked, then turn itself off if no malfunctions are present.
However, if after 15 seconds the “service engine soon” light blinks eight
times, it means that the vehicle is not ready for I/M testing. See the
Readiness for inspection/maintenance (I/M) testingin theFuel and
Refuelingchapter.
Solid illumination after the engine is started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction. Refer to
On-board diagnostics (OBD-II)in theFuel and Refuelingchapter. 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.
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. Have an authorized dealer service your vehicle immediately.

STARTING A GASOLINE ENGINE
When you start the engine, the idle speed increases, this helps to warm
up the engine. If the engine idle speed does not slow down automatically,
have your vehicle checked by an authorized dealer.
Note:
You can crank the engine for a total of 60 seconds (without the
engine starting) before the starting system temporarily disables. The
60 seconds does not have to be all at once. For example, if you crank the
engine three times for 20 seconds each time, without the engine starting,
you reached the 60-second time limit. A message appears in the
information display alerting you that you exceeded the cranking time. You
cannot attempt to start the engine for at least 15 minutes. After
15 minutes, you are limited to a 15-second engine cranking time. You need
to wait 60 minutes before you can crank the engine for 60 seconds again.

TRAILER SWAY CONTROL (IF EQUIPPED)
WARNING:Turning off trailer sway control increases the risk of
loss of vehicle control, serious injury or death. Ford does not
recommend disabling this feature except in situations where speed
reduction may be detrimental (such as hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.
Note:This feature does not prevent trailer sway, but reduces it once it
begins.
Note:This feature cannot stop all trailers from swaying.
Note:In some cases, if vehicle speed is too high, the system may turn
on multiple times, gradually reducing vehicle speed.
This feature applies your vehicle brakes at individual wheels and, if
necessary, reduces engine power. If the trailer begins to sway, the
stability control light flashes. The first thing to do is slow your vehicle
down, then pull safely to the side of the road and check for proper
tongue load and trailer load distribution. See theLoad Carryingchapter
for specific loading information.
RECOMMENDED TOWING WEIGHTS
Note:Do not exceed the trailer weight for your vehicle configuration
listed in the chart below.
Note:Be sure to take into consideration trailer frontal area. Do not
exceed:
•20 feet
2(1.86 meters2) trailer frontal area if your vehicle is not
equipped with a trailer towing package.
•40 feet
2(3.72 meters2) trailer frontal area if your vehicle is equipped
with a trailer towing package
Note:For high altitude operation, reduce the gross combined weight by
2% per 1000 feet (300 meters) starting at the 1000 foot (300 meter)
elevation point.
Note:Certain states require electric trailer brakes for trailers over a
specified weight. Be sure to check state regulations for this specified
weight. The maximum trailer weights listed may be limited to this
specified weight, as your vehicle’s electrical system may not include the
wiring connector needed to activate electric trailer brakes.

•Add particular accessories to your vehicle (e.g.; bug deflectors,
rollbars or light bars, running boards, ski racks).
•Drive with the wheels out of alignment.
DRIVING THROUGH WATER
WARNING:Do not drive through flowing or deep water as you
may lose control of your vehicle.
Note:Driving through standing water can cause vehicle damage.
Note:Engine damage can occur if water enters the air filter.
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 may be
limited. After driving through water
and as soon as it is safe to do so:
•Lightly press the brake pedal to
dry the brakes and to check that
they work.
•Check that the horn works.
•Check that the exterior lights work.
•Turn the steering wheel to check that the steering power assist works.
FLOOR MATS
WARNING:Always use floor mats that are designed to fit the
foot well of your vehicle. Only use floor mats that leave the pedal
area unobstructed. Only use floor mats that are firmly secured to
retention posts so that they cannot slip out of position and interfere
with the pedals or impair safe operation of your vehicle in other ways.
WARNING:Pedals that cannot move freely can cause loss of
vehicle control and increase the risk of serious personal injury.

If you notice any of the following:
•the engine coolant temperature gauge moves fully into the red (hot)
area
•the coolant temperature warning light illuminates
•the service engine soon indicator illuminates
1. Pull off the road as soon as safely possible and place the vehicle inP
(Park).
2. Leave the engine running until the coolant temperature gauge needle
moves away from the H range. After several minutes, if this does not
happen, follow the remaining steps.
3. Turn the engine off and wait for it to cool before checking the coolant
level.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
4. If the coolant level is normal, you may restart your engine and
continue on.
5. If the coolant is low, add coolant, restart the engine and take your
vehicle to an authorized dealer. SeeAdding engine coolantin this
chapter for more information.
Refer to fail-safe cooling for additional information.
What You Should Know About Fail-Safe Cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The fail-safe distance depends on ambient temperatures, vehicle load and
terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine coolant temperature gauge
will move to the red (hot) area and:
The coolant temperature warning light will illuminate.
The service engine soon indicator will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.

Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and foreign material contamination should be inspected
immediately by a qualified expert, such as the factory-trained technicians
at your dealership. Your vehicle’s oils and fluids should be changed at the
specified intervals or in conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system, or using
a Ford-approved flushing chemical.
Owner Checks and Services
Certain basic maintenance checks and inspections should be performed
every month or at six month intervals.
Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure.
Windshield washer fluid level.
Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary.
Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if
necessary.
Parking brake for proper operation.
Safety belts and seat latches for wear and function.
Safety warning lamps (brake, ABS, airbag, safety belt) for operation.
Washer spray and wiper operation. Clean or replace blades as
necessary.
