2015 FORD EXPLORER engine

GENERAL INFORMATION
Note: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. Have them inspected by an authorized dealer. If your vehicle
has continuous vibration or shudder in the steering wheel while braking,
have your vehicle inspected by an authorized dealer.
Note:Brake dust may accumulate on the wheels, even under normal
driving conditions. Some dust is inevitable as the brakes wear and does
not contribute to brake noise. See theVehicle Carechapter for wheel
cleaning instructions.
See theInstrument Clusterchapter for information on the
brake system warning light.
Wet brakes result in reduced braking efficiency. Gently press the brake
pedal a few times when driving from a car wash or standing water to dry
the brakes.
Brake Over Accelerator
In the event the accelerator pedal becomes stuck or entrapped, apply
steady and firm pressure to the brake pedal to slow your vehicle and
reduce engine power. If you experience this condition, apply the brakes
and bring your vehicle to a safe stop. Turn the engine off, shift to park
(P) and apply the parking brake. Inspect the accelerator pedal and the
area around it for any items or debris that may be obstructing its
movement. If none are found and the condition persists, have your
vehicle towed to the nearest authorized dealer.
Brake Assist
Brake assist detects when you brake heavily by measuring the rate at
which you press the brake pedal. It provides maximum braking efficiency
as long as you press the pedal. Brake assist can reduce stopping
distances in critical situations.

HILL START ASSIST
WARNING:The hill start assist feature does not replace the
parking brake. When you leave the vehicle, always apply the
parking brake and shift the transmission into park (P).
WARNING:You must remain in the vehicle once you have
activated the hill start assist feature.
WARNING:During all times, you are responsible for controlling
the vehicle, supervising the hill start assist system and
intervening, if required.
WARNING:If the engine is revved excessively, or if a
malfunction is detected when the hill start assist feature is active,
the hill start assist feature will be deactivated.
Hill start assist keeps your vehicle stationary long enough to move your
foot from the brake pedal to the accelerator pedal when your vehicle is
on a slope.
The brakes are released automatically once the engine has developed
sufficient drive to prevent the vehicle from rolling down the slope. This
is an advantage when pulling away on a slope, (for example from a car
park ramp, traffic lights or when reversing uphill into a parking space).
Using Hill Start Assist
1. Press the brake pedal to bring the vehicle to a complete standstill.
Keep the brake pedal pressed.
2. If the sensors detect that the vehicle is on a slope, the hill start assist
feature will be activated automatically.
3. When you remove your foot from the brake pedal, the vehicle will
remain on the slope without rolling away for approximately two or three
seconds. This hold time will automatically be extended if you are in the
process of driving off.
4. Drive off in the normal manner. The brakes will be released
automatically.

PRINCIPLES OF OPERATION
The traction control system helps avoid drive wheel spin and loss of
traction.
If your vehicle begins to slide, the system applies the brakes to individual
wheels and, when needed, reduces engine power at the same time. If the
wheels spin when accelerating on slippery or loose surfaces, the system
reduces engine power in order to increase traction.
USING TRACTION CONTROL
In certain situations (for example, stuck in snow or mud), turning the
traction control off may be beneficial as this allows the wheels to spin
with full engine power. Turn the traction control system off through the
information display. See theInformation Displayschapter.
System Indicator Lights and Messages
WARNING:If a failure has been detected within the Traction
Control System, the stability control light will illuminate steadily.
Verify that the Traction Control System was not manually disabled
using the information display control. If the stability control light still
illuminates steadily, have the system serviced by an authorized dealer
immediately. Operating your vehicle with Traction Control disabled
could lead to an increased risk of loss of vehicle control, vehicle
rollover, personal injury and death.
The stability control light temporarily illuminates on engine
start-up and flashes when a driving condition activates the
stability system.
The stability control off light temporarily illuminates on engine
start-up and stays on when the traction control system is
turned off or if a problem occurs in the stability system.
When the traction control system is turned off or on, a message appears
in the information display showing system status.

The system automatically activates when you start your engine. The
AdvanceTrac® with RSC® system cannot be completely turned off, but
the electronic stability control and roll stability control portions of the
system are disabled when the transmission is in reverse (R). You can
turn curve control off by using the terrain management system. See the
Terrain Managementchapter. You can also turn off the traction control
portion of the system independently. See theTraction Controlchapter.

Detection Issues
The radar sensor has a limited field of vision. It may not detect vehicles
at all or detect a vehicle later than expected in some situations. The lead
vehicle graphic will not illuminate if the system does not detect a vehicle
in front of you.
Detection issues can occur:
A. When driving on a different line
than the vehicle in front.
B. With vehicles that edge into your
lane. The system can only detect
these vehicles once they move fully
into your lane.
C. There may be issues with the
detection of vehicles in front when
driving into and coming out of a
bend or curve in the road.
In these cases the system may brake late or unexpectedly. You should
stay alert and intervene when necessary.
If the front end of your vehicle is hit or damaged, the radar sensing zone
may be altered causing missed or false vehicle detections. See your
authorized dealer to have the radar checked for proper coverage and
operation.

Cause Action
The surface of the radar in the
grille is dirty or obstructed in
some way.Clean the grille surface in front of
the radar or remove the object
causing the obstruction.
The surface of the radar in the
grille is clean but the message
remains in the display.Wait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed.
Heavy rain or snow is interfering
with the radar signals.Do not use the system in these
conditions because it may not
detect any vehicle ahead.
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signals.Do not use system in these
conditions because it may not
detect any vehicle ahead.
You are in a desert or remote area
with no other vehicles and no
roadside objects.Wait a short time or switch to
normal cruise control.
Due to the nature of radar technology, it is possible to get a blockage
warning and not be blocked. This can happen, for example, when driving
in sparse rural or desert environments. A false blocked condition will
either self-clear or clear after a key cycle.
Switching to Normal Cruise Control
WARNING:Normal cruise control will not brake due to slower
vehicles. Always be aware of which mode is selected and apply
the brakes when necessary.
You can manually change from adaptive cruise control to normal cruise
control through the information display.
The cruise control indicator light will replace the adaptive
cruise control indicator light if normal cruise control is selected.
The gap setting will not be displayed, the system will not
automatically respond to lead vehicles and automatic braking will not be
activated. The system will default to adaptive cruise control when the
engine is started.

Using the Systems
BLIS® turns on when the engine is started and the vehicle is driven
forward above 3 mph (5 km/h); it remains on while the transmission is in
D (Drive) or N (Neutral). If shifted out of D (Drive) or N (Neutral), the
system enters CTA mode. Once shifted back into D (Drive), BLIS® turns
back on when the vehicle is driven above 3 mph (5 km/h).
Note:BLIS® does not function in R (Reverse) or P (Park) or provide
any additional warning when a turn signal is on.
CTA detects approaching vehicles from up to 45 feet (14 meters) away
though coverage decreases when the sensors are blocked. Reversing
slowly helps increase the coverage area and effectiveness.
WARNING:To help avoid personal injury, NEVER use the CTA
system as a replacement for using the interior and exterior
mirrors and looking over your shoulder before backing out of a parking
space. CTA is not a replacement for careful driving.
In this first example, the left sensor is only partially obstructed; zone
coverage is nearly maximized.

•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lane.
•Severe weather conditions (see blocked sensor section).
•Debris build-up on the grille near the headlamps (see blocked sensor
section).
•Small distance to vehicle ahead.
•Steering wheel and pedal movements are large (very active driving
style).
•High interior temperatures, which may deactivate the illumination or
the warning lamps until the interior temperature reduces (audible
warning still sounds).
Certain conditions may reduce the visibility of the warning lamp;
therefore, it is recommended to keep the audible warning on.
If the front end of the vehicle is hit or damaged, the radar sensing zone
may be altered causing missed or false collision warnings. See your
authorized dealer to have your collision warning radar checked for
proper coverage and operation.
STEERING
Electric Power Steering
WARNING:The electric power steering system has diagnostic
checks that continuously monitor the system to ensure proper
operation. When a system error is detected a steering message will
appear in the information display.
