2009 FORD EXPLORER four wheel drive

The radar sensor is located behind the rear bumper/fascia. Always
keep the rear bumper/fascia free from snow, ice and large
accumulations of dirt. These elements may cause the system to
operate inaccurately.
If the vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
WARNING:For important information regarding safe operation
of this type of vehicle, seePreparing to drive your vehiclein
this chapter.
Four–wheel drive (4WD) supplies power to all four wheels. Do not use
4X4 High or 4X4 Low on dry, hard surfaced roads. Doing so will produce
excessive noise, increase tire wear and may damage drive components.
4X4 High and 4X4 Low are only intended for consistently slippery or
loose surfaces. The use of 4X4 High or 4X4 Low on these surfaces may
produce some noise, such as occasional clunks, but will not damage the
drive system.
If equipped with the Electronic Shift 4WD System, and 4WD Low
is selected while the vehicle is moving above 3 mph (5 km/h), the
4WD system will not engage. This is normal and should be no
reason for concern.Refer toShifting to/from 4WD Lowfor proper
operation.

Using the Control Trac 4WD system
4X4 AUTO- Provides electronically-controlled four-wheel drive with
power delivered to all four wheels as required for traction. This mode is
appropriate for all on-road driving conditions, including dry road
surfaces, wet pavement, snow and gravel.
4X4 HIGH (4WD High)- Provides locked four-wheel drive power to all
four wheels. This mode is not intended for use on dry pavement. This
mode is appropriate for severe winter and off-road conditions, such as
deep snow, ice or shallow sand.
4X4 LOW (4WD Low)- Provides locked four-wheel drive power when
extra power at reduced speeds is required. This mode is not
recommended for use on dry pavement. Use this mode for off-road,
low-speed operation or when extra power is required, such as climbing
steep grades, going through deep sand, or pulling a boat out of the
water.
Shifting between 4X4 AUTO (4WD Auto) and 4X4 HIGH (4WD High)
•Select 4X4 AUTO (4WD Auto) or 4X4 HIGH (4WD High) at any
forward speed.
Note:Do not perform this operation if the rear wheels are slipping.
Shifting to/from 4X4 LOW (4WD Low)
1. Bring the vehicle to a complete stop
2. Place the transmission in N (Neutral).
3. Press the desired 4WD position.
•If shifting into 4x4 LOW (4WD Low), wait for the 4X4 LOW light in
the instrument cluster to turnonindicating the shift is complete.
•If shifting out of 4X4 LOW (4WD Low), wait for the 4X4 LOW light in
the instrument cluster to turnoffindicating the shift is complete.
If any of the above shift conditions are not met, the shift will not occur
and the message center will display the appropriate information.

WARNING:If your vehicle is equipped with AWD, a spare tire of
a different size than the road tires should never be used. Such a
tire could make the vehicle difficult to control as well as result in
damage to driveline components.
WARNING:Utility and four-wheel drive vehicles arenot
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. Avoid sharp turns or abrupt maneuvers in
these vehicles.
Normal operation (4.0L engine vehicles only)
The AWD system is always active and requires no driver input. It is
capable of handling all road conditions, including street and highway
driving as well as off-road conditions such as deep snow, ice or shallow
sand.
Normal operation (4.6L engine vehicles only)
During normal operation the AWD system is in AWD AUTO mode (AWD
LOCKED will illuminate in the message center for four seconds when
you first start your vehicle). The 4X4 indicator in the instrument cluster
will also come on.
For instructions on selecting the AWD LOCKED mode, refer toMessage
centerin theDriver Controlschapter. This mode is not intended for use
on dry pavement. This mode is appropriate for severe winter or off-road
conditions such as deep snow, ice or shallow sand. The use of AWD
LOCKED on dry or hard surfaces may produce some noise, such as
occasional clunks, but will not damage the drive system.
Autolock operation (4.6L engine vehicles only)
If the AWD system begins to overheat, the system will place itself in the
Autolock mode:
•AWD LOCKED will be displayed in the message center for four
seconds and the 4x4 indicator light will illuminate in the instrument
cluster. A warning chime will also sound. This condition may clear
without any action being taken by the driver once the AWD system
has reached a safe operating temperature.
•The 4X4 indicator light in the instrument cluster will turn off when
the AWD system reaches a safe operating temperature and normal
AWD operation is restored.

Driving off-road with truck and utility vehicles
AWD and 4WD vehicles are specially equipped for driving on sand, snow,
mud and rough terrain and have operating characteristics that are
somewhat different from conventional vehicles, both on and off the road.
How your vehicle differs from other vehicles
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. To maintain
steering and braking control of your vehicle, you must have all four
wheels on the ground and they must be rolling, not sliding or spinning.
Basic operating principles
•Do not use 4WD High or 4WD Low on dry, hard surfaced roads. Doing
so will produce excessive noise, increase tire wear, reduce fuel
economy and may damage drive components. 4WD modes are only
intended for consistently slippery or loose surfaces.
•Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
•Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.
If your vehicle goes off the edge of the pavement
•If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
•It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.

•It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or roll over. Remember, your safety and the
safety of others should be your primary concern.
WARNING:Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel drive
vehicles arenotdesigned 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. Avoid sharp turns, excessive
speed and abrupt maneuvers in these vehicles. Failure to drive
cautiously could result in an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
If your vehicle gets stuck
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 few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
WARNING: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.
WARNING: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.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.

Emergency maneuvers
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle, i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency. Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
WARNING:Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel drive
vehicles arenotdesigned 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. Avoid sharp turns, excessive
speed and abrupt maneuvers in these vehicles. Failure to drive
cautiously could result in an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
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 this chapter. Information on transfer case maintenance can be
found in theMaintenance and Specificationschapter. You should
become thoroughly familiar with this information before you operate
your vehicle.

Parking
On some 4WD vehicles, when the transfer case is in the N (Neutral)
position, the engine and transmission are disconnected from the rest of
the driveline. Therefore, the vehicle is free to roll even if the automatic
transmission is in P (Park) or the manual transmission is in gear. Do not
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.
WARNING: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.
WARNING: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.
AWD Systems (if equipped)
AWD 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.
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:The Tire Pressure Monitoring System (TPMS) indicator light may
illuminate depending on how much air is released from your tires and/or
how long you drive the vehicle under these conditions.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.

Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although an AWD or a 4WD vehicle may
accelerate better than a two-wheel drive vehicle in snow and ice, it won’t
stop any faster, because as in other vehicles, braking occurs at all four
wheels. Do not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, avoid locking of the wheels. Use
a “squeeze” technique, push on the brake pedal with a steadily increasing
force which allows the wheels to brake yet continue to roll so that you
may steer in the direction you want to travel. If you lock the wheels,
release the brake pedal and repeat the squeeze technique. If your vehicle
is equipped with a Four Wheel Anti-Lock Brake System (ABS), apply the
brake steadily. Do not “pump” the brakes. Refer to theBrakessection of
this chapter for additional information on the operation of the anti-lock
brake system.
Never drive with chains on the front tires of AWD or 4WD vehicles
without also putting them on the rear tires. This could cause the rear to
slide and swing around during braking.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
