2006 FORD EXPLORER warning

Driving conditions that may activate AdvanceTractwith RSC include:
²Emergency lane-change
²Taking a turn too fast
²Quick maneuvering to avoid an accident, pedestrian or obstacle
AdvanceTractwith RSC button and icon functionality
The AdvanceTractwith RSC system automatically turns on each time
the engine is started. AdvanceTractwith RSC system status is indicated
by a warning indicator light with a ªsliding carº icon in the instrument
cluster that will flash when the system is active. In R (Reverse), ABS and
the Traction Control feature will continue to function, however ESC and
RSC are disabled.
The AdvanceTractwith RSC button
allows the driver to control certain
features of the AdvanceTractwith
RSC system below 25 mph (40
km/h). If an attempt is made to
disable the AdvanceTractwith RSC
system above 25 mph (40 km/h), the ªsliding carº icon will illuminate
solid if pressed momentarily, however, the AdvanceTractwith RSC
system will remain enabled until the vehicle speed drops below 25 mph
(40 km/h). Pressing the AdvanceTractwith RSC button momentarily will
disable engine Traction Control, ESC, and RSC and illuminate the ªsliding
carº icon solid. From the default/start-up state, the AdvanceTractwith
RSC system will have no lights illuminated (ªsliding carº lamp off). The
AdvanceTractwith RSC ªsliding carº lamp will illuminate when the
AdvanceTractwith RSC button is pressed momentarily.
When the AdvanceTractwith RSC system has been turned off (pressing
the AdvanceTractwith RSC button momentarily) the ªsliding carº lamp
will illuminate solid.
Pressing and holding the AdvanceTractwith RSC button for more than
five seconds will further disable the brake portion of the Traction Control
feature and the ªsliding carº icon will flash momentarily, then illuminate
solid. The ªsliding carº icon will illuminate solid if pressed momentarily.
All these conditions are normal during AdvanceTractwith RSC
operation. Refer to the following table.

Do not alter or modify your vehicle's suspension or steering; the
resulting changes to the vehicle's handling can adversely affect
the AdvanceTractwith RSC system.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a AdvanceTractwith
RSC event is an indication that at least some of the tires have
exceeded their ability to grip the road; this may lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death. If you experience a severe road event, SLOW DOWN.
If a failure is detected in the AdvanceTractwith RSC system, and the
AdvanceTractwith RSC button has not been pushed, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced by an authorized dealer immediately.
STEERING
To prevent damage to the power steering system:
²Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running
²Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
Driving

If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your authorized dealer.
Driving with a 5±speed automatic transmission
This vehicle is equipped with an adaptive Transmission Shift Strategy.
Adaptive Shift Strategy offers the optimal transmission operation and
shift quality. When the vehicle's battery has been disconnected for any
type of service or repair, the transmission will need to relearn the normal
shift strategy parameters, much like having to reset your radio stations
when your vehicle battery has been disconnected. The Adaptive
Transmission Strategy allows the transmission to relearn these operating
parameters. This learning process could take several transmission
upshifts and downshifts; during this learning process, slightly firmer
shifts may occur. After this learning process, normal shift feel and shift
scheduling will resume.
Driving
218

²Allows upshifts by moving gearshift lever.
²Will not downshift into 1 (First) at high speeds; allows for 1 (First)
when vehicle reaches slower speeds.
Forced downshifts
²Allowed in D (Drive) only.
²Depress the accelerator to the floor.
²Allows transmission to select an appropriate gear.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The Reverse Sensing System (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
To help avoid personal injury, please read and understand the
limitations of the reverse sensing system as contained in this
section. Reverse sensing is only an aid for some (generally large and
fixed) objects when moving in reverse on a flat surface at ªparking
speedsº. Inclement weather may also affect the function of the RSS;
this may include reduced performance or a false activation.
To help avoid personal injury, always use caution when in R
(Reverse) and when using the RSS.
This system is not designed to prevent contact with small or
moving objects. The system is designed to provide a warning to
assist the driver in detecting large stationary objects to avoid damaging
the vehicle. The system may not detect smaller objects, particularly
those close to the ground.
Driving

leave the vehicle unattended with the transfer case in the N (Neutral)
position. Always set the parking brake fully and turn off the ignition
when leaving the vehicle.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your authorized dealer.
4WD Systems
4WD uses all four wheels to power the vehicle. This increases traction,
enabling you to drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels
through a transfer case. On 4WD
vehicles, the transfer case allows
you to select 4WD when necessary.
Information on transfer case
operation and shifting procedures
can be found in theDriving
chapter. Information on transfer
case maintenance can be found in theMaintenance and Specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
Normal characteristics
On some 4WD models, the initial shift from two-wheel drive to 4x4 while
the vehicle is moving can cause some momentary clunk and ratcheting
sounds. This is the front drivetrain coming up to speed and the
automatic locking hubs engaging and is not cause for concern.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
Note:If your vehicle is equipped with the Tire Pressure Monitoring
System (TPMS), the system indicator light may illuminate depending on
Driving

Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
What you should know about fail-safe cooling (4.6L V8 engine only)
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The ªfail-safeº distance depends on ambient temperatures, vehicle load
and terrain.
Fail-safe cooling and engine oil temperature sensor (4.6L V8 only)
If the engine coolant and/or engine oil overheat, the vehicle limits engine
power before engine damage can occur. The instrument cluster can
provide up to four indicators to warn of coolant and/or oil overheat.
Warning lights/indicators Fail Safe cooling Oil Overheat Only*
(Engine oil pressure)OnOffÐwith normal
oil pressure
(Service engine soon)On Off
(Engine coolant temperature)On On
Engine coolant temperature gage Hot (H) area Hot (H) area
*Oil overheat warnings can be triggered in severe driving conditions, such as
towing heavy loads over mountainous terrain in extreme hot temperatures.
If the engine fluids reach even hotter temperatures, fail-safe cooling
protects the engine by limiting engine power further and may disable the
air conditioning system. The engine will automatically switch to
alternating cylinder operation. Each disabled cylinder acts as an air
pump and cools the engine. During this mode, the engine will run rough.
If continued operation increases the engine temperature to a critical
range, the engine will shut down. Steering and braking effort will
increase. Once engine temperature cools, the engine can be restarted.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the vehicle
with caution. The vehicle will not be able to maintain high speed operation and
the engine will run rough. Remember that the engine is capable of completely
shutting down automatically to prevent engine damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.

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
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theRefill capacities
section of this chapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of fuel remaining in the fuel
tank after the fuel gauge indicates empty.
The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. 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.
For consistent results when filling the fuel tank:
²Turn the engine/ignition switch to the off position prior to refueling,
an error in the reading will result if the engine is left running.
²Use the same filling rate setting (low Ð medium Ð high) each time
the tank is filled.
²Allow no more than two automatic click-offs when filling.
²Always use fuel with the recommended octane rating.
²Use a known quality gasoline, preferably a national brand.
²Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
Maintenance and Specifications
299

²Close 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.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
²Use only the specified fuel listed.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
²Have the items listed inscheduled maintenance information
performed according to the specified schedule.
The scheduled maintenance items listed inscheduled maintenance
informationare essential to the life and performance of your vehicle
and to its emissions system.
If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Illumination of the
indicator, charging system warning light or the
temperature warning light, fluid leaks, strange odors, smoke or loss of
engine power, could indicate that the emission control system is not
working properly.
