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.

Maintenance and care
190

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 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.
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.
Cleaning plastic exterior parts
Use vinyl cleaner for routine
cleaning. Clean with a tar remover
if necessary. Do not clean plastic
parts with thinners, solvents or
petroleum-based cleaners.

2Your vehicle's rear axle is
equipped with synthetic rear axle
lubricant. Rear axles containing
synthetic lubricant are lubricated
for life. These lubricants are not to
be checked or changed unless a
leak is suspected, service required
or the axle assembly has been
submerged in water. The axle
lubricant should be changed any
time the axle has been submerged
in water. For Traction±Lok add
118 ml (4 oz.) of additive friction
modifier C8AZ±19B546±A, Ford
specification EST-M2C118±A, to
your rear axle whenever the
lubricant is changed.
