If you get a flat tire while driving,
do not apply the brakes heavily.
Instead, gradually reduce the
speed while holding the steering
wheel firmly. Move the vehicle to a
safe spot off to the side of the
road.

Oil filters
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,
startup engine noises or knock
may be experienced. It is
recommended that you use the
appropriate Motorcraft oil filter (or
another brand meeting Ford
specifications) for your engine
application.
Checking engine oil
Check the engine oil each time you
fuel your vehicle.
Check the engine oil level more
frequently if the vehicle is carrying
a heavy load, towing a trailer,
idling for extended periods (like
police, taxi or shuttle service
vehicles) or driven at high speeds
for extended periods of time.
To check the oil:
1. Make sure the vehicle is on level
ground. If the engine is warm, turn
the engine off and wait a few
minutes for the oil to drain into
the oil pan.
2. Set the parking brake and
ensure the gearshift is latched in P
(Park) (automatic transmission) or
1 (First) (manual transmission).
3. Open the hood. Protect yourself
from engine heat.
4. Locate and carefully remove the

Maintenance and care

Before adding any fluid, make sure
the correct type will be used. This
information is indicated on the
dipstick.
Do not drive the vehicle if the fluid
level is below the bottom hole on
the blade type dipstick (4R70W
transmission) or below the COLD
area on the bullet type dipstick
(E4OD transmission) and outside
temperatures are above 10ÉC
(50ÉF).
Your vehicle does not use up
transmission fluid. However, it is
recommended that you check the
transmission fluid at least twice a
year. 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.
It is preferable to check the
transmission fluid level at normal
operating temperature, after
approximately 32 km (20 miles) of
driving. However, you can check
the fluid level without driving to
obtain a normal operating
temperature if the outside
temperature is above 10ÉC (50ÉF).
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 the fluid
to cool before checking.
