WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets
Ford specification WSB-M8B16–A2.
Refer toLubricant specifications
in this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
If you operate your vehicle in temperatures below 4.5°C (40°
F), use washer fluid with antifreeze protection. Failure to use
washer fluid with antifreeze protection in cold weather could result in
impaired windshield vision and increase the risk of injury or accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance guide for the appropriate intervals
for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait a few minutes for the oil to drain into the
oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(automatic transaxle) or 1st (manual transaxle).
4. Open the hood. Protect yourself from engine heat.

•2.0L Zetec engine
6. Wipe the indicator clean. Insert the indicator fully, then remove it
again.
•If the oil level isbetween the MIN and MAX marks(2.0L SPI/2.3
engine) orbetween ADD and FULL(2.0L Zetec engine), the oil
level is acceptable.DO NOT ADD OIL.

•If the oil level is below the MIN/ADD mark, add enough oil to raise the
level within the MIN-MAX/ADD-FULL range.
•Oil levels above the MAX/FULL mark may cause engine damage. Some
oil must be removed from the engine by a service technician.
7. Put the indicator back in and ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the engine oil level is not within the normal range, add only certified
engine oil of the recommended viscosity. Remove the engine oil filler cap
and use a funnel to pour the engine oil into the opening.

3. Recheck the engine oil level. Make sure the oil level is not above the
MAX mark on the engine oil level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
tightly until clicks are heard, or until it is snug.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.
Engine oil and filter recommendations
Look for this certification
trademark.
Use SAE 5W-20 engine oil.
Only use oils“Certified For Gasoline Engines”by the American
Petroleum Institute (API). To protect your engine’s warranty use
Motorcraft SAE 5W-20 or an equivalent 5W-20 oil meeting Ford
specification WSS-M2C153–H.SAE 5W-20 oil provides optimum fuel
economy and durability performance meeting all requirements for
your vehicle’s engine.
Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil according to the appropriate schedule listed in
the scheduled maintenance guide.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.

When lifting a plastic-cased battery, excessive pressure on the
end walls could cause acid to flow through the vent caps,
resulting in personal injury and/or damage to the vehicle or battery.
Lift the battery with a battery carrier or with your hands on opposite
corners.
Keep batteries out of reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or clothing. Shield your eyes
when working near the battery to protect against possible splashing of
acid solution. In case of acid contact with skin or eyes, flush
immediately with water for a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed, call a physician immediately.
Battery posts, terminals and related accessories contain lead and
lead compounds.Wash hands after handling.
Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park) (automatic transaxle) or the neutral
position (manual transaxle), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 16 km (10 miles) or more to
relearn the idle and fuel trim strategy.
•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
When the battery is disconnected or a new battery installed, the
transmission must learn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will fully update transmission operation to its optimum shift feel.
