bulb works. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Standard 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.
Optional 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
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
indicator 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 indicator 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 toOn
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.

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:When mounting replacement tires and wheels, you
should not exceed the maximum pressure indicated on the
sidewall of the tire to set the beads without additional precautions
listed below. If the beads do not seat at the maximum pressure
indicated, re-lubricate and try again.
When inflating the tire for mounting pressures up to 20 psi (138 kPa)
greater than the maximum pressure on the tire sidewall, the following
precautions must be taken to protect the person mounting the tire:
1. Make sure that you have the correct tire and wheel size.
2. Lubricate the tire bead and wheel bead seat area again.
3. Stand at a minimum of 12 ft (3.66 m) away from the tire wheel
assembly.
4. Use both eye and ear protection.
For a mounting pressure more than 20 psi (138 kPa) greater than the
maximum pressure, an authorized dealer or other tire service
professional should do the mounting.
Always inflate steel carcass tires with a remote air fill with the person
inflating standing at a minimum of 12 ft (3.66 m) away from the tire
wheel assembly.
Important:Remember to replace the wheel valve stems when the road
tires are replaced on your vehicle.
It is recommended that the two front tires or two rear tires generally be
replaced as a pair.
The tire pressure sensors mounted in the wheels are not designed to be
used in aftermarket wheels.
The use of wheels or tires not recommended by Ford Motor Company
may affect the operation of your tire pressure monitoring system (if
equipped).
If the TPMS indicator is flashing, your TPMS is malfunctioning. Your
replacement tire might be incompatible with your TPMS, or some
component of the TPMS may be damaged (if equipped).
Safety practices
Driving habits have a great deal to do with your tire mileage and safety.

WARNING: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 traction
control 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.
The traction control switch, located
on the instrument panel to the right
of the climate control system, has
an indicator light that illuminates when the system is off. The traction
control system will automatically turn on every time the ignition is
turned off and on. The traction control system should normally be left
on.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching the traction control system off. This may allow
excess wheel spin to “dig” the vehicle out and enable a successful
“rocking” maneuver.
If a system fault is detected, the traction control active light will
illuminate, the traction control button will not turn the system on or off
and your vehicle should be serviced by an authorized dealer.

•loose or worn steering components
•improper steering alignment
If any steering components are serviced or replaced, install new
fasteners (many are coated with thread adhesive or have prevailing
torque features which may not be re-used). Never re-use a bolt or nut.
Torque fasteners to specifications inWorkshop Manual.
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
ELECTRONIC LOCKING DIFFERENTIAL (ELD) (IF EQUIPPED)
The electronic locking differential (ELD) is a device housed in the rear
axle which allows both rear wheels to turn at the same speed. It provides
added traction on slippery and/or off road surfaces, particularly when
one wheel is on a poor traction surface. The ELD may be locked or
unlocked by the vehicle operator and can be engaged or disengaged on
the fly. 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. It is not recommended for use on good
traction surfaces such as dry pavement. Doing so may result in abnormal
driving behavior and noise while cornering and excessive tire wear.
The ELD is affected by the following conditions of your vehicle:
•On 2WD vehicles and 4WD vehicles in 2H (4X2) or 4H (4X4 High),
the ELD will not engage if the vehicle speed is above 25 mph
(40 km/h).
•On 2WD vehicles and 4WD vehicles in 2H (4X2) or 4H (4X4 High),
the ELD will automatically disengage at speeds above 25 mph
(40 km/h) and will automatically reengage at speeds below 19 mph
(30 km/h).
•On 4WD vehicles in 4L (4X4 Low), the ELD can be engaged at any
speed and will not automatically disengage.
Activating the electronic locking differential (ELD)
For vehicles equipped with an
electronic shift 4WD system:
Pull the knob on the 4WD control
toward you. The
indicator light
will display in the instrument
cluster.
