2015 FORD EXPLORER traction

Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down. Whenever driving on a hill, determine beforehand the
route you will use. Do not drive over the crest of a hill without seeing
what conditions are on the other side. Do not drive in reverse over a hill
without the aid of an observer.
When climbing a steep slope or hill, start in a lower gear rather than
downshifting to a lower gear from a higher gear once the ascent has
started. This reduces strain on the engine and the possibility of stalling.
If you do stall out, Do not try to turn around because you might roll
over. It is better to back down to a safe location.
Apply just enough power to the wheels to climb the hill. Too much
power will cause the tires to slip, spin or lose traction, resulting in loss of
vehicle control.
Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral; instead,
disengage overdrive or manually
shift to a lower gear. When
descending a steep hill, avoid
sudden hard braking as you could
lose control. When you brake hard,
the front wheels cannot turn and if
they are not turning, you will not be able to steer. The front wheels have
to be turning in order to steer the vehicle.
Since your vehicle has anti-lock brakes, apply the brakes steadily. Do not
“pump” the brakes.
Driving on snow and ice
WARNING:If you are driving in slippery conditions that require
tire chains or cables, then it is critical that you drive cautiously.
Keep speeds down, allow for longer stopping distances and avoid
aggressive steering to reduce the chances of a loss of vehicle control
which can lead to serious injury or death. If the rear end of the vehicle
slides while cornering, steer in the direction of the slide until you
regain control of the vehicle.
4WD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.

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.

PRINCIPLES OF OPERATION
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and wheel or tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTrac® system. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac®
system. Install any aftermarket stereo loudspeaker as far as possible
from the front center console, the tunnel, and the front seats in order
to minimize the risk of interfering with the AdvanceTrac® sensors.
Reducing the effectiveness of the AdvanceTrac® system could lead to
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTrac® system is an indication that at least
some of the tires have exceeded their ability to grip the road; this could
reduce the operator’s ability to control the vehicle potentially resulting
in a loss of vehicle control, vehicle rollover, personal injury and death. If
your AdvanceTrac® system activates, SLOW DOWN.
The AdvanceTrac® with Roll Stability Control™ system helps you keep
control of your vehicle when on a slippery surface. The electronic
stability control portion of the system helps avoid skids and lateral slides,
curve control assists in vehicle handling in following the road during
adverse maneuvering and roll stability control helps avoid a vehicle
rollover. The traction control system helps avoid drive wheel spin and
loss of traction. See theTraction Controlchapter for details on traction
control system operation.

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.

TERRAIN MANAGEMENT (IF EQUIPPED)
This system optimizes drivability and comfort as well as maximizing
traction while operating on different types of terrain.
Turn the control located on the center console to choose between the
following modes:
1.Grass/Gravel/Snowmode should be selected where a firm surface is
covered with loose or slippery material such as packed snow, ice, water,
grass, or a thin layer of gravel or sand. For deep gravel or sand, select
Sand mode. If the vehicle cannot gain traction in deep snow, turning off
the traction control system may help (turn traction control back on when
traction is regained). See theTraction Controlchapter.
2.Sandmode should be selected in soft dry sand or deep gravel. If
crossing wet sand that may be sufficiently deep enough for the wheels to
sink into the surface, select Mud/Ruts mode.
3.Mud/Rutsmode should be selected for muddy, rutted, soft, or uneven
terrain.
4.Normalmode is for on-road conditions and should be selected before
driving on surfaces which are similar to a hard road surface or once the
need for a special mode has passed. Select Normal mode when towing a
trailer.
Note:Cruise control is available only in Normal and Snow modes.
Note:The Sand and Mud/Ruts modes are for off-road use only.
Note:The curve control portion of the AdvanceTrac® system is
unavailable when Sand or Mud/Ruts is selected.

•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.

GENERAL INFORMATION
Notice to Utility Vehicle, Van and Truck Owners
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles. To reduce the risk of serious
injury or death from a rollover or other crash you must:
•Avoid sharp turns and abrupt maneuvers.
•Drive at safe speeds for the conditions.
•Keep tires properly inflated.
•Never overload or improperly load your vehicle.
•Make sure every passenger is properly restrained.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
All occupants must wear seat belts. Children and infants must use
appropriate restraints to minimize the risk of injury or ejection.
Utility vehicles, vans and trucks handle
differently than passenger cars in the
various driving conditions that are
encountered on streets, highways and
off-road. Utility vehicles, vans and
trucks are not designed for cornering
at speeds as high as passenger cars
any more than low-slung sports cars
are designed to perform satisfactorily
under off-road conditions.
Four-Wheel Drive System (If Equipped)
WARNING:Do not become overconfident in the ability of
four-wheel drive vehicles. Although a four-wheel drive vehicle
may accelerate better than a two-wheel drive vehicle in low-traction
situations, it will not stop any faster than two-wheel drive vehicles.
Always drive at a safe speed.
A vehicle equipped with four-wheel drive (when selected) has the ability
to use all four wheels to power itself. This increases traction which may
enable you to safely drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot.
