2008 FORD EXPLORER wheel

Driving while you tow
When towing a trailer:
•To ensure proper “break-in” of powertrain components, do not trailer
tow during the first 1,000 miles (1600 km) of a new vehicle.
•To ensure proper “break-in” of powertrain components during the first
500 miles (800 km) of trailer towing, drive no faster than 70 mph (112
km/h) with no full throttle starts.
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with an automatic transmissionsection in theDriving
chapter.)
•Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gaugein theInstrument Cluster
chapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
informationfor more information.
Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.

•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (112 km/h) with no full throttle starts.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.
•do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
•causing internal damage to the components.
•affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING (ALL WHEELS ON THE GROUND)
Follow these guidelines for your specific powertrain combination to tow
your vehicle with all four wheels on the ground (such as behind a
recreational vehicle).
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.

Rear Wheel Drive (RWD) 4x2 vehicles:
This applies to all 4x2 trucks/sport utilities with rear wheel drive
capability.
•Place the transmission in N (Neutral).
•Maximum speed is 35 mph (56 km/h).
•Maximum distance is 50 miles (80 km).
If a distance of 50 miles (80 km) or a speed of 35 mph (56 km/h) must
be exceeded, you must disconnect the driveshaft. Ford recommends the
driveshaft be removed/installed only by a qualified technican at an
authorized dealer. See your authorized dealer for driveshaft
removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid loss, damage to the driveshaft and internal
transmission components.
4WD vehicles with electronic shift transfer case (Neutral tow kit
accessory):
On vehicles equipped with 4WD, an accessory is available that allows you
to tow your vehicle, behind another vehicle, with all the wheels on the
ground. Contact your authorized dealer for more details. Do not tow your
vehicle with all wheels on the ground unless you install the neutral tow
kit as vehicle damage may occur.

STARTING
Positions of the ignition
1. OFF/LOCK, shuts off the engine
and all accessories/locks the steering
wheel, gearshift lever and allows key
removal.
2. ACC, allows the electrical
accessories such as the radio to
operate while the engine is not
running. This position also unlocks
the steering wheel.
3. ON, all electrical circuits
operational. Warning lights illuminated. Key position when driving.
4. START, cranks the engine. Release the key as soon as the engine
starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine. For more information on starting the vehicle, refer to
Starting the enginein this chapter.
Extended idling at high engine speeds can produce very high
temperatures in the engine and exhaust system, creating the risk
of fire or other damage.
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.
Do not start your vehicle in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic. Always open the garage door
before you start the engine. SeeGuarding against exhaust fumesin
this chapter for more instructions.

Starting the engine
1. Turn the key to 3 (ON) without
turning the key to 4 (START). If
there is difficulty in turning the key,
rotate the steering wheel until the
key turns freely. This condition may
occur when:
•the front wheels are turned
•a front wheel is against the curb
2. Turn the key to 4 (START), then
release the key as soon as the
engine starts. Excessive cranking could damage the starter.
Note:If the engine does not start on the first try, turn the key to OFF,
wait 10 seconds and try again. If the engine still fails to start, press the
accelerator to the floor and try again; this will allow the engine to crank
with the fuel shut off in case the engine is flooded with fuel.
This vehicle has a computer assisted cranking system which assists in
starting the engine. If the ignition key is turned to 4 (START) and then
released when the engine begins cranking, the engine may continue
cranking for up to 10 seconds or until the vehicle starts
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least one inch (2.5 cm) or adjust the heating
or air conditioning to bring in fresh air.

•Make sure that when in operation, the extension cord plug /engine
block heater cord plug connection is free and clear of water in order
to prevent possible shock or fire.
•Be sure that areas where the vehicle is parked are clean and clear of
all combustibles such as petroleum products, dust, rags, paper and
similar items.
•Be sure that the engine block heater, heater cord and extension cord
are solidly connected. A poor connection can cause the cord to
become very hot and may result in an electrical shock or fire. Be sure
to check for heat anywhere in the electrical hookup once the system
has been operating for approximately a half hour.
•Finally, have the engine block heater system checked during your fall
tune-up to be sure it’s in good working order.
How to use the engine block heater
Ensure the receptacle terminals are clean and dry prior to use. To clean
them, use a dry cloth.
Depending on the type of factory installed equipment, your engine block
heater system may consume anywhere between 400 watts or 1000 watts
of energy per hour. Your factory installed block heater system does not
have a thermostat; however, maximum temperature is attained after
approximately 3 hours of operation. Block heater operation longer than 3
hours will not improve system performance and will unnecessarily use
additional electricity.
Make sure system is unplugged and properly stowed before driving the
vehicle. While not in use, make sure the protective cover seals the
prongs of the engine block heater cord plug.
BRAKES
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
and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.

Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an Anti-lock Braking System (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. Noise from the ABS pump motor and
brake pedal pulsation may be observed during ABS braking and the
brake pedal may suddenly travel a little farther as soon as ABS braking is
done and normal brake operation resumes. These are normal
characteristics of the ABS and should be no reason for concern.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
steering control during hard braking and on slippery surfaces. However,
the ABS does not decrease stopping distance.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled,
normal braking is still effective. If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.

ADVANCETRACWITH ROLL STABILITY CONTROL™ (RSC)
STABILITY ENHANCEMENT SYSTEM
The AdvanceTracwith RSC system provides stability enhancement
features such as Roll Stability Control™ (RSC), Electronic Stability
Control (ESC) and Traction Control (TCS) for certain driving situations.
The system includes an AdvanceTracwith RSC on/off button, and a
“sliding car” icon
in the instrument cluster.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTracwith RSC performs a system self-check. During
AdvanceTracwith RSC operation you may experience the following:
•A rumble, grunting, or grinding noise after startup and when driving
off
•A slight deceleration of the vehicle
•The AdvanceTracwith RSC indicator light will flash when the system
is activated.
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
Traction Control
Traction Control helps your vehicle maintain traction, when driving on
slippery and/or hilly road surfaces, by detecting and controlling wheel
spin. Excessive wheel spin is controlled by momentarily reducing engine
power and/or applying the anti-lock brakes. Traction Control is a driver
aid that helps your vehicle.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTracwith RSC system off by pressing the AdvanceTrac
with RSC button momentarily. This will allow your tires to “dig” for
traction. Remember to switch the AdvanceTracwith RSC system back
on once the vehicle is no longer stuck.
If the AdvanceTracwith RSC system is activated excessively in a short
period of time, the brake portion of the system will disable to allow the
brakes to cool down. In this situation, Traction Control will use only
engine power reduction to help control the wheels from over-spinning.
When the brakes have cooled down, the system will again function
normally. Anti-lock braking, RSC and ESC are not affected by this
condition and will function normally during the cool-down period.
