WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, have the
respective system inspected immediately.
Check engine:If this light
illuminates while driving, it is a
possible indication that one of the
engine’s emission control systems
has failed.
Check fuel cap:Illuminates when
the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Service
engine soon warning light to come
on.
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 dealership. Illumination after releasing the parking brake
indicates low brake fluid level and the brake system should be inspected
immediately by your servicing dealership.

Driving conditions which may activate AdvanceTrac
include:
•Accelerating on a slippery surface
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Hitting a patch of ice
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Hitting a curb while turning
•Cornering at excessive speeds while towing a heavily loaded trailer
(refer toTrailer Towingin this chapter)
The AdvanceTrac
system automatically turns on when the engine is
started. However, the system does not function when the vehicle is
traveling in R (Reverse).
The AdvanceTrac
button allows
the driver to control the availability
of the AdvanceTrac
system.
AdvanceTrac
system status is
indicated by a TRAC ACTIVE
indicator light in the instrument
cluster when the system is active.
If a failure is detected in the
AdvanceTrac
system, the TRAC
OFF indicator light in the
instrument cluster will stay on. Vehicle equipped with a message center
will also have CHECK ADVANCETRAC shown in the display.
If the vehicle is stuck in snow or mud or when driving in deep sand,
switching off the AdvanceTrac
system may be beneficial so the wheels
are allowed to spin. If your vehicle seems to lose engine power while
driving in deep sand or very deep snow, switching off the AdvanceTrac

stability enhancement feature will restore full engine power and will
enhance momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac
performs a system self-check. During AdvanceTrac

operation you may experience the following:
•A rumble or grinding noise
Driving
137

•A slight deceleration of the vehicle
•The TRAC ACTIVE indicator light will illuminate
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during AdvanceTrac
operation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTrac
system. Also, do not install a stereo
loudspeaker near the front center console or under either front
seat. The speaker vibrations can adversely affect the
AdvanceTrac
sensors located in this area.
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 an AdvanceTrac
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.
STEERING
To prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an underinflated tire
•uneven tire wear
•loose or worn suspension
components•loose or worn steering
components
•improper steering alignment

SERVICE RECOMMENDATIONS
To help you service your vehicle:
•We highlight do-it-yourself items in the engine compartment for easy
location.
•We provide a scheduled maintenance guide which makes tracking
routine service easy.
If your vehicle requires professional service, your dealership can provide
the necessary parts and service. Check yourWarranty Guide/Owner
Information Guideto 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
•Do not work on a hot engine.
•Make sure that nothing gets caught in moving parts.
•Do not work on a vehicle with the engine running in an enclosed
space, unless you are sure you have enough ventilation.
•Keep all open flames and other lit material away from the battery and
all fuel related parts.
Working with the engine off
1. Set the parking brake and shift to P (Park).
2. Turn off the engine and remove the key.
3. Block the wheels.
Working with the engine on
1. Set the parking brake and shift to P (Park).
2. Block the wheels.

Maintenance and Specifications
188

Change your engine oil and filter according to the appropriate schedule
listed in the scheduled maintenance guide.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.
BATTERY
Your vehicle is equipped with a
Motorcraft maintenance-free battery
which normally does not require
additional water during its life of
service.
Check the battery electrolyte level under severe usage. Refer to the
Scheduled Maintenance Guide.
If the level is low, add plain tap water. If possible, use distilled water. If
the battery needs water often, have the charging system checked.
Note:The electrolyte level in each cell should be at the“level indicator”.
Do not overfill the battery cells.
Keep the top of the battery clean and dry. Also, make certain the battery
cables are always tightly fastened to the terminals. If your battery has a
cover/shield, make sure it is reinstalled after cleaning or battery
replacement.
Batteries normally produce explosive gases which can cause
personal injury. Therefore, do not allow flames, sparks or lighted
substances to come near the battery. When working near the battery,
always shield your face and protect your eyes. Always provide proper
ventilation.

•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.
•Do not mix with recycled coolant unless from a Ford-approved
recycling process (seeUse of Recycled engine coolantsection).
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
water to the“cold full”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.
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.
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. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the“cold fill range”or the“cold full”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 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.
