Readiness for Inspection/Maintenance (I/M) testing
Some state/provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration. Your vehicle may not pass the I/M
test if the service engine soon
indicator is on or not working
properly (bulb is burned out), or if the OBD-II system has determined
that some of the emission control systems have not been properly
checked. In this case, the vehicle is considered not ready for I/M testing.
If the service engine soon
indicator is on or the bulb does not
work, the vehicle may need to be serviced. Refer toOn-board
diagnostics (OBD-II)in this chapter.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If the service engine
soon
indicator blinks eight times, it means that the vehicle is not
ready for I/M testing; if the service engine soon
indicator stays on
solid, it means that the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second 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. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.

BRAKE/CLUTCH FLUID
Brake and clutch (if equipped) systems are supplied from the same
reservoir.
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the MIN and
MAX lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range, the performance of the
system could be compromised; seek
service from your authorized dealer
immediately.
TRANSMISSION FLUID
Checking automatic transmission fluid
The automatic transmission does not have an underhood transmission
fluid dipstick.
Refer to yourscheduled maintenance informationfor scheduled
intervals for fluid checks and changes. Your transmission does not
consume fluid. However, the fluid level should be checked if the
transmission is not working properly, (i.e., if the transmission slips or
shifts slowly) or if you notice some sign of fluid leakage.
Transmission fluid should be checked and, if required, added by
an authorized dealer.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.

Checking and adding manual transmission fluid (if equipped)
1. Clean the filler plug. It is located
on the passenger side of the
transmission.
2. Remove the filler plug and
inspect the fluid level.
3. Note: For vehicles equipped with a V6 engine, the correct manual
transmission fill level is at the lower edge of the filler hole. For vehicles
equipped with a V8 engine, the correct manual transmission fill level is
1/2 inch (1.3 cm) below the edge of the filler hole.
•Fill level for V6
•Fill level for V8
4. Add enough fluid through the filler opening to bring the fluid up to
the recommended levels.
5. Install and tighten the fill plug securely.

Be sure to ask your Ford or Lincoln Mercury dealership service advisor
or technician about the multi-point vehicle inspection. It’s a
comprehensive way to perform a thorough inspection of your vehicle. It’s
your checklist that gives you immediate feedback on the overall
condition of your vehicle. You’ll know what’s been checked, what’s okay,
as well as those things that may require future or immediate attention.
The multi-point vehicle inspection is one more way to keep your vehicle
running great!
Mutli-point inspection - Recommended at every visit
❑Check and top-up fluid levels: brake, coolant recovery reservoir, manual and automatic transmission (if equipped with an
underhood dipstick), power steering (if equipped) and window washer
❑Inspect tires for wear and check air pressure, including spare.
❑Check exhaust system for leaks, damage, loose parts and foreign material.
❑Check battery performance.
❑Check operation of horn, exterior lamps, turn signals and hazard warning lights.
❑Check radiator, coolers, heater and air conditioning hoses.
❑Inspect windshield washer spray and wiper operation.
❑Check windshield for cracks, chips and pitting.
❑Inspect for oil and fluid leaks.
❑Inspect engine air filter.
❑Inspect half shaft dust boots, if equipped.
❑Check shocks and struts and other suspension components for leaks and damage.
❑Inspect steering and linkage.
❑Inspect accessory drive belt(s).
❑Inspect clutch operation, if equipped.
