Uplevel message center
Note:Some warning lights are
reconfigurable telltale (RTT)
indicator lights and will illuminate in
the message center. These lights
function the same as the other
warning lights. The first three
positions will only display one
warning telltale at a time; the last
three positions can cycle between
different warning telltales.
Service engine soon:The service
engine soon indicator light
illuminates when the ignition is first
turned to the on position to check
the bulb and to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. Normally, the service engine soon
light will stay on until the engine is cranked, then turn itself off if no
malfunctions are present. However, if after 15 seconds the service engine
soon light blinks eight times, it means that the vehicle is not ready for
I/M testing. See theReadiness for Inspection/Maintenance (I/M)
testingin theMaintenance and Specificationschapter.
Solid illumination after the engine is started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction. Refer to
On-board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.
WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.

Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
when the engine is not running, or in a position between on and start, or
by applying the parking brake when the ignition is turned to the on
position.
If the brake system warning light does not illuminate at this time, seek
service immediately from your authorized dealer. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your authorized dealer.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.

Illuminated entry
The interior lamps and parking lamps illuminate when the remote entry
system is used to unlock the door(s).
The illuminated entry system will turn off the lights if:
•the ignition switch is turned to the on position, or
•the remote transmitter lock control is pressed, or
•the 7•8 and the 9•0 controls on the keyless entry keypad are
pressed, or
•after 25 seconds of illumination.
The dome lamp control (if equipped) mustnotbe set to the off position
for the illuminated entry system to operate.
The lights will not turn off if:
•they have been turned on with the dimmer control, or
•any door is open.
The battery saver will shut off the interior lamps 30 minutes after the
ignition has been turned to the off position, 10 minutes after if the dome
lamp is off, and 30 minutes after if the dome lamp switch is left on.
Remote start (if equipped)
Your vehicle may be equipped with the remote start feature which allows
you to start the engine from outside the vehicle. If your transmitter has
a
icon, you have remote start. The remote start feature has an
extended operating range which allows you to remote start your vehicle
from a farther distance from your vehicle. All the buttons have this
increased range performance capability when equipped with remote
start.
Many states and provinces have restrictions for the use of remote start.
Check your local and state or provincial laws for specific requirements
regarding remote start systems.
Note:Do not use remote start if your vehicle is low on fuel.
WARNING:To avoid exhaust fumes, do not use remote start if
your vehicle is parked indoors or areas that are not well
ventilated.

•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 power per hour. Your factory installed block heater system does not
have a thermostat; however, maximum temperature is attained after
approximately three hours of operation. Block heater operation longer
than three 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 toWarning lights and
chimesin 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.

When AdvanceTracwith RSCperforms a normal system self-check,
some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTracwith RSCyou may
experience the following:
•A slight deceleration of the vehicle
•The stability control light will flash.
•A vibration in the pedal when your foot is on the brake pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.
Traction control system (TCS)
Traction control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem: engine traction control and brake traction
control. Engine traction control works to limit drive-wheel spin by
momentarily reducing engine power. Brake traction control works to limit
single wheel spin by momentarily applying the brakes to the wheel that
is slipping. Traction control is most active at low speeds.
During either engine or brake TCS events, the stability control light in
the instrument cluster will flash.
If the TCS is activated excessively in a short period of time, the braking
portion of the system may become temporarily disabled to allow the
brakes to cool down. In this situation, TCS will use only engine power
reduction or transfer to help control the wheels from over-spinning.
When the brakes have cooled down, the system will regain all features.
Anti-lock braking, RSC, and ESC are not affected by this condition and
will continue to function during the cool-down period.
The engine traction control and brake traction control system may be
deactivated in certain situations. But single wheel spin brake traction
control is always on. See theSwitching off AdvanceTracwith RSC
section following.

Switching off AdvanceTracwith RSC
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTracwith RSC
system may be beneficial because the wheels are allowed to spin. This
will restore full engine power and will enhance momentum through the
obstacle.
To switch off certain features of the AdvanceTracwith RSCsystem,
press the stability control button. Full features of the AdvanceTracwith
RSCsystem can be restored by pressing the button again or by turning
off and restarting the engine.
If you switch off the AdvanceTracwith RSCsystem, the stability
control off light will illuminate steadily. Pressing the stability control
button again will turn off the stability control off light.
In R (Reverse), ABS and the engine traction control and brake traction
control features will continue to function; however, ESC and RSCare
disabled.

Trailer sway control
Your vehicle is equipped with trailer sway control. When properly
equipped, trailer sway control will use the vehicle’s AdvanceTracwith
RSCsystem to detect and help reduce trailer sway by applying brake
force at individual wheels and, if necessary, by reducing engine power.
WARNING:Trailer sway control does not prevent a trailer from
swaying, it mitigates the sway from increasing once it has
occurred. If you are experiencing trailer sway it is likely that the trailer
is improperly loaded for the correct tongue weight or the speed of the
vehicle and trailer is too high. Pull the vehicle-trailer over to a safe
location to check the trailer weight distribution and tongue load and
reduce speed to a safe level while towing. If trailer sway is
experienced, SLOW DOWN.Note:When trailer sway control is
activated, cruise control is disabled.
During trailer sway control events, the stability control light in the
instrument cluster will flash momentarily. The message center will also
displayTRAILER SWAY REDUCE SPEED.In some cases when trailer

All engines
If the steering wanders or pulls equipped with either an EPS or a
hydraulic steering system, 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.
LIMITED-SLIP AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
limited-slip axle functions like a standard rear axle. The axle may exhibit
a slight noise or vibration in tight turns with low vehicle speed. This is
normal behavior and indicates the axle is working.
Electronic locking differential (ELD) axle (if equipped)
This axle provides added traction on slippery and/or off-road surfaces,
particularly when one wheel is on a poor traction surface. In normal
driving conditions the rear axle function as a standard axle. The ELD
may be locked or unlocked by the vehicle operator. Refer toFour-wheel
drive (4WD) operationsection in this chapter for further detail on ELD
function and usage. When the axle is unlocked it will function like a
standard rear axle. When the axle is locked it will not allow the rear
wheels to rotate at different speeds when turning. The ELD axle is not
recommended for use on good traction surfaces such as dry pavement.
Doing so may result in abnormal driving behavior while cornering and
excessive tire wear.
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.

If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
“Tread Lightly” is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford Motor
Company joins the U.S. Forest Service and the Bureau of Land
Management in encouraging you to help preserve our national forest and
other public and private lands by “treading lightly.”
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
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.

For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
distilled water to the FULL COLD level. For all other vehicles which have
a coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add 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 (a translucent 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. Fill the coolant reservoir slowly with the proper coolant mixture, to
within the COLD FILL RANGE or the FULL COLD level on the reservoir.
If you removed the radiator cap in an overflow system, fill the radiator
until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. Cap must be tightly
installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration (refer
toChecking engine coolant). If the concentration is not 50/50
(protection to –34°F/–37°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.
