PREPARING TO START YOUR VEHICLE
Engine starting is controlled by the ignition system. This system meets
all Canadian Interference-Causing Equipment standard requirements
regulating the impulse electrical field strength of radio noise.
When starting a fuel-injected engine, avoid pressing the accelerator
before or during starting. Only use the accelerator when you have
difficulty starting the engine. For more information on starting the
vehicle, refer toStarting the enginein this chapter.
Extended idling at high engine speeds can produce very high
temperatures in the engine and exhaust system, creating the risk
of fire or other damage.
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.
Do not start your vehicle in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic. Always open the garage door
before you start the engine. SeeGuarding against exhaust fumesin
this chapter for more instructions.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important safety precautions
A computer system controls the engine's idle revolutions per minute
(RPM). When the engine starts, the idle RPM runs faster to warm the
engine. If the engine idle speed does not slow down automatically, have
the vehicle checked.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer to the
Seating and safety restraintschapter.
2. Make sure the headlamps and vehicle accessories are off.

Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, items, 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 diagnostic (OBD-II) 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 OBD-II system is reset to a ªnot ready for I/M testº condition. To
ready the OBD-II 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.
EXTERIOR BULBS
Replacing exterior bulbs
Check the operation of the following lamps frequently:
²Headlamps
²Foglamps
²High-mount brakelamp
²Brakelamps
Maintenance and care
222

²Turn signals
²License plate lamp
²Tail lamps
²Back-up lamps
Do not remove lamp bulbs unless they can be replaced immediately with
new ones. If a bulb is removed for an extended period of time,
contaminants may enter the lamp housings and affect lamp performance.
Replacing headlamp bulbs
Handle a halogen headlamp bulb carefully and keep out of
children's reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.
If the bulb is accidentally touched, it should be cleaned with rubbing
alcohol before being used.
To remove the headlamp bulb:
1. Make sure headlamp switch is in
OFF position, then lift hood and
open the hinged headlamp cover.
2. Release clip and disconnect the
electrical connector from the bulb.

Maintenance and care

3. Remove the bulb retaining ring by
rotating it counterclockwise (when
viewed from the rear) about 1/8
turn to free it from the bulb socket,
and slide the ring off the plastic
base. Keep the ring to retain the
new bulb.
4. Remove the old bulb from the lamp assembly by gently pulling it
straight back out of the lamp assembly.
To install the new bulb:
1. With the flat side of the new
bulb's plastic base facing upward,
insert the glass end of the bulb into
the lamp assembly. You may need to
turn the bulb left or right to align
the grooves in the plastic base with
the tabs in the lamp assembly. When
the grooves are aligned, push the bulb into the lamp assembly until the
plastic base contacts the rear of the lamp assembly.
2. Install the bulb retaining ring over the plastic base until it contacts the
rear of the socket by rotating clockwise until you feel a ªstop.º
3. Install the electrical connector into the rear of the plastic base until it
snaps, locking it into position.
4. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you should
not need to align it again.
Replacing front parking lamp/turn signal bulbs
1. Remove screw from the lamp
assembly.
2. Disengage lamp assembly.

License plate lamp bulbs
To change the license plate bulbs:
1. Remove two screws and the
license plate lamp assembly from
the liftgate.
2. Remove bulb socket from lamp
assembly by turning
counterclockwise.
3. Pull the bulb out from socket and
push in the new bulb.
4. Install the bulb socket in lamp
assembly turning it clockwise,
5. Install the lamp assembly on
liftgate with two screws.

AIMING THE HEADLAMPS
The alignment of your headlamps should be checked by a qualified
service technician if:
²Oncoming motorists frequently signal you to deactivate your high
beams, and your high beams are not activated.
²The headlamps do not seem to provide enough light for clear night
vision.
²The headlamp beams are pointed substantially away from a slightly
down and to the right position.
CLEANING AND CARING FOR YOUR VEHICLE
Refer to the ªCustomer Assistance Guideº for a list of Ford-approved
cleaners, polishes and waxes.
Washing your vehicle
Wash your vehicle regularly with
cold or lukewarm water. Never use
strong detergents or soap. If your
vehicle is particularly dirty, use a
quality car wash detergent. Always
use a clean sponge, washing glove
or similar device and plenty of water
for best results. To avoid spots,
avoid washing when the hood is still
warm, immediately after or during
exposure to strong sunlight.
During winter months, it is especially important to wash the vehicle on a
regular basis. Large quantities of dirt and road salt are difficult to
remove and also cause damage to the vehicle.
Remove any exterior accessories, such as antennas, before entering a car
wash. If you have wax applied to the vehicle at a commercial car wash, it
is recommended that you clean the wiper blades and windshield as
described inCleaning the wiper blades and windshield.
After washing, apply the brakes several times to dry them.
