STEERING
Your vehicle is equipped with an Electric Power-Assisted Steering
(EPAS) system. There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Under extreme usage conditions, the steering effort may
increase. This occurs to prevent overheating and permanent damage to
your steering system. If this should occur, you will neither lose the ability
to steer the vehicle manually nor will it cause permanent damage.
Typical steering and driving maneuvers will allow the system to cool and
steering assist will return to normal.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
PREPARING TO DRIVE
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
Utility vehicles and trucks have larger tires and increased ground
clearance, giving the vehicle a higher center of gravity than a passenger
car.

Driving on hilly or sloping terrain
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.Avoid driving crosswise or turning on steep
slopes or hills.A danger lies in losing traction, slipping sideways and
possibly rolling over. 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
turnaround 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 can’t turn and if
they aren’t turning, you won’t be
able to steer. The front wheels have to be turning in order to steer the
vehicle. Rapid pumping of the brake pedal will help you slow the vehicle
and still maintain steering control.
Since your vehicle has anti-lock brakes, apply the brakes steadily. Do not
“pump” the brakes.

Note:Use of Motorcraft Cooling System Stop Leak Pellets or an
equivalent product meeting Ford specification WSS-M99B37-B6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
Note:When adding more than 1 quart (.95L) of coolant, it is necessary
to use the coolant bleed valve. Failure to bleed the cooling system when
adding engine coolant may cause engine damage. Refer to the Cooling
section of theWorkshop Manual.
•Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Specialty Orange Engine Coolant, meeting Ford
specification WSS-M97B44-D, or DEX-COOLbrand with the
factory-filled coolant.Mixing Motorcraft Specialty Orange Engine
Coolant or any orange-colored extended life product such as
DEX-COOLbrand with your factory filled coolant can result in
degraded corrosion protection.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
•Do not use alcohol, methanol, brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol
and other liquids can cause engine damage from overheating or
freezing.
•Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
Add the proper mixture of coolant and water to the cooling system by
following these steps:
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (an opaque plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.

3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Open the coolant bleed valve on the back of the engine water outlet.
(SeeIdentifying components in the engine compartmentearlier in
this section for the location of the bleed valve). If the bleed valve leaks
coolant when opened, there is no air in the engine. If the bleed valve
does not leak coolant when opened, leave it open and continue to the
next steps.
6. Fill the coolant reservoir slowly with the proper coolant mixture.
7. Close the bleed valve when coolant begins to seep from it.
8. Continue filling to within the “COLD FILL RANGE” or the “FULL
COLD” level on the reservoir. Reinstall the cap on the coolant reservoir.
Turn the cap until it is tightly installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration.
Refer to theChecking engine coolantsection. If the concentration is
not 50/50 (protection to –34° F [–36° C]), drain some coolant and adjust
the concentration. It may take several drains and additions to obtain a
50/50 coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage.
Recycled engine coolant
Ford Motor Company does NOT recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.

6. Install the dipstick, making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be in
the crosshatch zone for normal operating temperature.
Low fluid level
Do not drive the vehicle if the fluid
level is at the bottom of the dipstick
and the outside temperatures are
above 50°F (10°C).
Correct fluid level
The transmission fluid should be checked at normal operating
temperatures 185°F-200°F (85°C-93°C) on a level surface. The normal
operating temperature can be reached after approximately 20 miles
(30 km) of driving.
The transmission fluid should be in
the crosshatch zone if at normal
operating temperature (185°F-200°F
[85°C-93°C]).
High fluid level
Fluid levels above the crosshatch
zone may result in transmission
failure. An overfill condition of
transmission fluid may cause shift
and/or engagement concerns and/or
possible damage.
High fluid levels can be caused by
an overheating condition.
