2007 FORD FOCUS engine

Illumination of theindicator, charging system warning light or the
temperature warning light, fluid leaks, strange odors, smoke or loss of
engine power could indicate that the emission control system is not
working properly.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
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 yourWarranty Guidefor complete emission warranty
information.
On board diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the On
Board Diagnostics System (OBD-II). This OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle. When the
indicator illuminates, the OBD-II system has detected a malfunction.
Temporary malfunctions may cause the
indicator to illuminate.
Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been securely tightened. SeeFuel filler
capin this chapter.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel and/or properly tightening the fuel cap. After three
driving cycles without these or any other temporary malfunctions
present, the
indicator should turn off—A driving cycle consists of a
cold engine startup followed by mixed city/highway driving. No additional
vehicle service is required.
If the
indicator remains on, have your vehicle serviced at the first
available opportunity.

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 diagnostics system. If the
indicator is on, refer to the
description in theWarning lights and chimessection of the
Instrument Clusterchapter. Your vehicle may not pass the I/M test with
the
indicator on.
If the vehicle’s powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a “not ready for I/M test”
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
•First, at least 10 minutes of driving on an expressway or highway.
•Next, 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.
POWER STEERING FLUID
Check the fluid. Refer to the
scheduled maintenance
informationfor service
maintenance schedules.
1. Start the engine and let it run
until it reaches normal operating
temperature.
2. Turn the steering wheel left and
right several times.
3. Turn the engine off.
4. Check the fluid level.
5. If the fluid is below the MIN line, add fluid in small amounts until it
reaches the correct level (between the MIN and MAX lines).
Use only MERCON
AT F.
BRAKE/CLUTCH FLUID
Brake and clutch 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 your
brake system could be
compromised; seek service from
your authorized dealer immediately.
TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to yourscheduled maintenance informationfor scheduled
intervals for fluid checks and changes. Your transaxle does not consume
fluid. However, the fluid level should be checked if the transaxle is not
working properly, i.e., if the transaxle slips or shifts slowly or if you
notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 20 miles [30 km]). If your vehicle has been
operated for an extended period at high speeds, in city traffic
during hot weather or pulling a trailer, the vehicle should be
turned off for about 30 minutes to allow fluid to cool before
checking.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer toIdentifying components in the engine compartment
in this chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be in
the designated areas for normal operating temperature.

If an overfill occurs, excess fluid
should be removed by an authorized
dealer.
An overfill condition of
transmission fluid may cause
shift and/or engagement
concerns and/or possible damage.
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.
2. Remove the filler plug and
inspect the fluid level.
3. Fluid level should be at the
bottom of the opening.
4. Add enough fluid through the
filler opening so that the fluid level
is at the bottom of the opening.
5. Install and tighten the fill plug
securely.
Use only fluid that meets Ford specifications. Refer to theMaintenance
product specifications and capacitiessection in this chapter.

1Approximate dry fill capacity including transmission fluid cooling system, actual refill capacities
will vary based on vehicle application and transmission fluid cooling system (i.e. coolers size,
cooling lines, auxiliary cooler capacities). The amount of transmission fluid and fluid level should
be set by the indication on the dipstick’s normal operating range.
The manual transmission service refill capacity is determined by filling the transaxle to the bottom
of the filler hole with the vehicle on a level surface.2Ensure the correct automatic transmission fluid is used. Transmission fluid requirements are
indicated on the dipstick or on the dipstick handle or as listed in this Owner’s Guide. Check the
container to verify the fluid being added is of the correct type. Refer to yourscheduled
maintenance informationto determine the correct service interval.
Some transmission fluids may be labeled as dual usage, such as MERCON
and MERCON
V.
These dual usage fluids are not to be used in an automatic transmission that requires use of the
MERCON
type fluid. However, these dual usage fluids may be used in transmissions that require
the MERCON
V type fluid.
MERCON
and MERCON
V type fluids are not interchangeable. DO NOT mix MERCON

and MERCON
V. Use of a transmission fluid that indicates dual usage (MERCON
and
MERCON
V) in an automatic transmission application requiring MERCON
may cause
transmission damage. Use of any fluid other than the recommended fluid may cause
transmission damage.3Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C930-A and the API Certification mark.4Add the coolant type originally equipped in your vehicle.
