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:TheCheck Engine
indicator light illuminates when the
ignition is first turned to the ON
position to check the bulb. Solid
illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer to
OBD-IIin theMaintenance and Specificationschapter. 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.
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.
Check fuel cap:Illuminates when
the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Check
engine warning light to come on,
refer toFuel filler capin theMaintenance and Specificationchapter.
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 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 dealer immediately.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.
Air bag readiness:If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also sound when a malfunction in the
supplemental restraint system has been detected.
Safety belt:Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Charging system:Illuminates when
the battery is not charging properly.
Engine oil pressure:Illuminates
when the oil pressure falls below the
normal range, refer toEngine oilin
theMaintenance and
specificationschapter.
Multi-function: Automatic
transaxle/cooling system (On
SPI, Zetec E or automatic
transaxle vehicles only):
Momentarily illuminates when the
ignition is turned to the ON position and the engine is off. If the light
illuminates while driving, have your vehicle serviced.

If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
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 a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
Under normal operating conditions, brake dust may accumulate on the
wheels. Some brake dust is inevitable as brakes wear and does not
contribute to brake noise. The use of modern friction materials with
emphasis on improved performance and environmental considerations
can lead to more dust than in the past. Brake dust can be cleaned by
weekly washing with soapy water and a soft sponge. Heavier deposits can
be removed with Motorcraft Wheel and Tire Cleaner (ZC-37–A).
Four-wheel anti-lock brake system (ABS) (if equipped)
Your vehicle may be 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; any
pulsation or mechanical noise you may feel or hear is normal.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance.
ABS warning lamp
ABS
TheABSlamp in the instrument cluster momentarily illuminates when
the ignition is turned to ON. If the light does not illuminate during start
up, remains on or flashes, the ABS may be disabled and may need to be
serviced.
Driving
111

Even when the ABS is disabled,
normal braking is still effective. (If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system serviced immediately.)
Parking brake
To set the parking brake (1), pull
the parking brake handle up as far
as possible.
The BRAKE warning lamp will
illuminate and will remain
illuminated until the parking brake
is released.
To release, press and hold the button (2), pull the handle up slightly,
then push the handle down.
Always set the parking brake fully and make sure that the
gearshift is securely latched in P (Park) (automatic
transmission) or in 1 (First) (manual transmission).
TRACTION CONTROL(IF EQUIPPED)
Your vehicle may be equipped with a Traction Control
system. This
system helps you maintain the stability and steerability of your vehicle,
especially on slippery road surfaces such as snow- or ice-covered roads
and gravel roads. The system will allow your vehicle to make better use
of available traction in these conditions.
During Traction Control
operation,
the traction control active light will
illuminate, you may hear an electric
motor type of sound coming from
the engine compartment and the
engine will not“rev-up”when you push further on the accelerator. This
is normal system behavior and should be no reason for concern.

The Traction Control
switch is
located on the center console, by
the gearshift lever. The Traction
Control
system will automatically
turn on every time the ignition is
turned off and 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.
AdvanceTracstability enhancement system (if equipped)
The AdvanceTrac
system provides a stability enhancement feature as
well as a traction enhancement feature. Excessive wheel slip is
controlled by momentarily reducing engine power and/or rapidly applying
the anti-lock brakes. If the vehicle begins to slide excessively left or right
or spin out. AdvanceTrac
will attempt to correct the sliding motion by
applying brake force at individual tires and, if necessary, by reducing
engine power.
If the AdvanceTrac
system is activated and deactivated excessively in a
short period of time, the brake portion of the system will shut down to
allow the brakes to cool down. A limited AdvanceTrac
function using
only engine power reduction will still help control the wheels from
over-spinning. When the brakes have cooled down, the system will again
function normally. Anti-lock braking is not affected by this condition and
will function normally during the cool-down period.
AdvanceTrac
enhances your vehicle’s stability during maneuvers that
require all available tire traction, like in wet/snowy/icy road conditions
and/or when performing emergency maneuvers. In an emergency
lane-change, the driver will experience better overall vehicle traction,
and have better control of the vehicle.
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
Driving
113

•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“sliding car”icon
indicator light in the instrument
cluster when the system is active.
If a failure is detected in the AdvanceTrac
system, the“sliding car”
icon indicator light in the instrument cluster will stay on.
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
•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.
