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.

TRACTION CONTROL(IF EQUIPPED)
Your vehicle may be equipped with a Traction Controlsystem. 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 Controloperation,
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.
At speeds below 85 km/h (53 mph), both the engine and the brake
system will be used to control wheel spin; at speeds above 85 km/h (53
mph), only engine torque reduction is used. When the Traction Control
system switched off, the braking system will still be used to control
wheel spin at speeds below 40 km/h (25 mph).
The Traction Controlswitch is
located on the center console, by
the gearshift lever. The Traction
Controlsystem 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 Controlsystem 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 Controlbutton will not turn the system on or
off and your vehicle should be serviced.
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).

PAINT CHIPS
Your dealer has touch-up paint and sprays to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jam) to
your dealer to ensure you get the correct color.
•Remove particles such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout before repairing paint chips.
•Always read the instructions before using the products.
ALUMINUM WHEELS AND WHEEL COVERS
Aluminum wheels and wheel covers are coated with a clearcoat paint
finish. In order to maintain their shine:
•Clean weekly with Motorcraft Wheel and Tire Cleaner (ZC-37–A),
which is available from your dealer. Heavy dirt and brake dust
accumulation may require agitation with a sponge. Rinse thoroughly
with a strong stream of water.
•Never apply any cleaning chemical to hot or warm wheel rims or
covers.
•Some automatic car washes may cause damage to the finish on your
wheel rims or covers. Chemical-strength cleaners, or cleaning
chemicals, in combination with brush agitation to remove brake dust
and dirt, could wear away the clearcoat finish over time.
•Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
•To remove tar and grease, use Motorcraft Bug and Tar Remover
(ZC-42), available from your dealer.
ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal.
The engine cooling fan may operate for several minutes after the
engine is turned off. Do not start maintenance work until the fan
has stopped operating.
When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
