WARNING LIGHTS AND CHIMES
Low fuel
Illuminates as an early reminder of a
low fuel condition indicated on the
fuel gauge (refer toFuel Gaugein
this chapter for more information).
When refueling, after the light
comes on, the amount of fuel that is added will be less than the
advertised capacity since there is fuel still in the tank. The ignition must
be in the ON position for this lamp to illuminate. The lamp will also
illuminate for several seconds after the ignition is turned to the ON
position regardless of the fuel level to ensure your bulb is working.
Service engine soon
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This
system is commonly known as the
On Board Diagnostics System (OBD
II). The OBD II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD II system also assists the
service technician in properly servicing your vehicle.
TheService Engine Soonindicator light illuminates when the ignition is
first turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine's emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.

BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle's brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a ªmetal-to-metal,º ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
Anti-lock brake system (ABS)
On vehicles equipped with an anti-lock braking system (ABS), a noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle's
anti-lock brake system. The ABS performs a self-check after you start
the engine and begin to drive away. A brief mechanical noise may be
heard during this test. This is normal. If a malfunction is found, the ABS
warning light will come on. If the vehicle has continuous vibration or
shudder in the steering wheel while braking, the vehicle should be
inspected by a qualified service technician.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensates for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.
Driving

When driving through water, determine the depth; avoid water higher
than the bottom of the hubs (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
After driving through mud, clean off residue stuck to rotating driveshafts,
halfshafts and tires. Excess mud stuck on tires and rotating driveshafts
causes an imbalance that could damage drive components.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Water intrusion into the transmission may damage the
transmission.
If the rear axle is submerged in water, the rear axle lubricant should be
checked and changed, if necessary. The rear axle is filled with a
synthetic lubricant and does not normally require a lubricant change for
the life of the vehicle. Rear axle lubricant quantities should not need to
be checked unless a leak is suspected.
Driving on hilly or sloping terrain
When driving on a hill, avoid driving crosswise or turning on steep
slopes. You could lose traction and slip sideways. Drive straight up,
straight down or avoid the hill completely. Know the conditions on the
other side of a hill before driving over the crest.
When climbing a steep 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.
When descending a steep hill, avoid sudden braking. Shift to a lower gear
when added engine braking is desired.
When speed control is on and you are driving uphill, your vehicle speed
may drop considerably, especially if you are carrying a heavy load.
If vehicle speed drops more than 16 km/h (10 mph), the speed control
will cancel automatically. Resume speed with accelerator pedal.
If speed control cancels after climbing the hill, reset speed by pressing
and holding the SET ACCEL button (to resume speeds over 50 km/h (30
mph).

SERVICE RECOMMENDATIONS
To help you service your vehicle:
²We highlight do-it-yourself items in the engine compartment for easy
location.
²We provide a Scheduled Maintenance Guide which makes tracking
routine service easy.
If your vehicle requires professional service, your dealership can provide
necessary parts and service. Check your ªWarranty Guideº to find out
which parts and services are covered.
Use only recommended fuels, lubricants, fluids and service parts
conforming to specifications. Motorcraft parts are designed and built to
provide the best performance in your vehicle.
PRECAUTIONS WHEN SERVICING YOUR VEHICLE
Be especially careful when inspecting or servicing your vehicle.
²Do not work on a hot engine.
²When the engine is running, make sure that loose clothing, jewelry or
long hair does not get caught up in moving parts.
²Do not work on a vehicle with the engine running in an enclosed
space, unless you are sure you have enough ventilation.

Do not let the fluid level in the reservoir for the master cylinder
fall below the MIN mark. If master cylinder runs dry, this may
cause the brakes to fail.
WINDSHIELD WASHER FLUID
Checking and adding washer fluid
Check the washer fluid whenever
you stop for fuel. The reservoir is
highlighted with a
symbol.
If the level is low, add enough fluid
to fill the reservoir. In very cold
weather, do not fill the reservoir all
the way.
Only use a washer fluid that meets Ford specifications. Refer to
Lubricant specificationsin theCapacities and specificationschapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle's paint finish, wiper blades or washer system.
Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling
system components.
Checking and adding washer fluid for the liftgate
Washer fluid for the liftgate is supplied by the same reservoir as the
windshield.
ENGINE COOLANT
Checking engine coolant
Your engine's cooling system has been factory-filled with a 50/50 mixture
of distilled water and Ford Premium Engine Coolant E2FZ-19549-AA (in

converter and other emission control components continue to work
properly:
²Use only the specified fuel listed.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
²Have the items listed in your Scheduled Maintenance Guide performed
according to the specified schedule.
The scheduled maintenance items listed in the Scheduled Maintenance
Guide are essential to the life and performance of your vehicle and to its
emissions system.
If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
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.
Illumination of the ªCheck Engineº light, charging system warning light
or the temperature warning light, fluid leaks, strange odors, smoke or
loss of engine power, could indicate that the emission control system is
not working properly.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle's emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult your ªWarranty Guideº for complete emission warranty
information.

Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If your ªCheck Engine/Service Engine
Soonº light is on, refer to the description in theWarning Lights and
Chimessection of theInstrumentationchapter. Your vehicle may not
pass the I/M test with the ªCheck Engine/Service Engine Soonº light on.
If the vehicle's powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a ªnot ready for I/M testº
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
²First, at least 10 minutes of driving on an expressway or highway.
²Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
