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, reference the applicable light
description in theWarning Lights
and Chimessection of your
owners guide. Your vehicle may
not pass the I/M test with the

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.

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
Maintenance and care
198

antennas, before entering a car
wash.
After washing, apply the brakes
several times to dry them.
Waxing your vehicle
Wax when water stops beading on
the surface. This could be every
three or four months, depending
on operating conditions.
Use only carnauba or
synthetic-based waxes. Remove
any bugs and tar before waxing
vehicle. Use cleaning fluid or
alcohol with a clean cloth to
remove. Use tar remover to
remove any tar spots.
Repairing paint chips
Minor scratches or paint damage
from road debris may be repaired
with touch-up , paint repair foil or
aerosol paint spray from the Ford
accessory line. Observe the
application instructions on the
products.
Remove particles such as bird
droppings, tree sap, insect
remains, tar spots, road salt and
industrial fallout immediately.
Cleaning the wheels
Wash with the same detergent as
the body of your vehicle. Do not
use acid-based wheel cleaners,
steel wool, fuel or strong
detergents. Never use abrasives
that will damage the finish of
special wheel surfaces. Use a tar
remover to remove grease and tar.
Maintenance and care
199

Cleaning the engine
Engines are more efficient when
they are clean because grease and
dirt buildup keep the engine
warmer than normal. When
washing:
²Take care when using a power
washer to clean the engine. The
high pressure fluid could
penetrate the sealed parts and
cause damage.
²Do not spray with cold water to
avoid cracking the engine block
or other engine components.
²Cover the highlighted areas to
prevent water damage when
cleaning the engine.
²Never wash or rinse the engine
while it is running; water in the
running engine may cause
internal damage.
