SERVICING YOUR VEHICLE
Service recommendations
To help you service your vehicle:
²We highlight do-it-yourself items
in the engine compartment for
easy location.
²As possible, we design parts that
can be replaced without tools.
²We provide you with a ªService
Guideº which makes tracking
routine service for your vehicle
easy.
If your vehicle requires
professional service, your
dealership can provide necessary
parts and service. Check your
ªWarranty Information Bookletº to
find out which parts and services
are covered.
Use only recommended fuels,
lubricants, fluids and service parts
conforming to specifications.
Motorcraft parts are designed and

Precautions when servicing
your vehicle
Be especially careful when
inspecting or servicing your

²If you must work with the
engine running, avoid wearing
loose clothing or jewelry that

could get caught in moving
parts. Take precautions with
long hair.
²Do not work on a vehicle with
the engine running in an
enclosed space, unless you are
sure you have enough
ventilation.
²Keep all lit cigarettes, open
flames and other lit material
away from the battery and all
fuel related parts.
If you disconnect the battery, the
engine must ªrelearnº its idle
conditions before your vehicle will
drive properly, as explained in
Batteryin this chapter.

ENGINE OIL
Oil specifications
Use WSS-M2C153±F motor oil
CERTIFIED FOR GASOLINE
ENGINES by the American
Petroleum Institute.
Engine oils with an SAE 5W-30
viscosity and displaying the
American Petroleum Institute
certification mark are preferred for
your vehicle. They provide the best
engine performance, fuel economy
and engine protection for all
climates down to ±25ÉC (-15ÉF).
Do not use:
²ªnon-detergentº oils
²oils labeled API SA, SB, SC, SD,
SE, SF or SG
²additional engine oil additives,
oil treatments or engine
treatments
Additional engine oil additives, oil
treatments, or engine treatments
are never needed and could, under
certain conditions, lead to engine
damage which is not covered by
your Ford warranty.
Synthetic engine oils which are
CERTIFIED and of the preferred
viscosity may be used in your
engine. The engine oil and oil filter
must still be changed according to
the ªService Guide.º

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

Snow tires and chains
Snow tires must be the
same size and grade as the
tires you currently have on your
vehicle.
The tires on your vehicle have all
weather treads to provide traction
in rain and snow.
However, in some climates, you
may need to use snow tires and
chains.
Follow these guidelines when using
snow tires and chains.
²Use only SAE Class ªSº chains.
²Install chains securely, verifying
that the chains do not touch any
wiring, brake lines or fuel lines.
²4x2: Install tire chains on rear
tires (of all sizes) only.
²4x4: Install tire chains on rear
tires (of all sizes), and on front
tires of size P235/70R16 only.
²Drive cautiously. If you hear the
chains rub or bang against your
vehicle, stop and retighten the
chains. If this does not work,
remove the chains to prevent
damage to your vehicle.
²If possible, avoid fully loading
your vehicle.
²Remove the tire chains when
they are no longer needed. Do
not use tire chains on dry roads.
²The suspension insulation and
bumpers will help prevent
vehicle damage. Do not remove

these components from your
vehicle when using snow tires
and chains.
FUEL
Important safety precautions
Do not overfill the fuel
tank. The pressure in an
overfilled tank may cause
leakage and lead to fuel spray
and fire.
If you do not use the
proper fuel cap, the
pressure in the fuel tank can
damage the fuel system or cause
it to work improperly in a
collision.
The fuel system may be
under pressure. If the fuel
cap is venting vapor or if you
hear a hissing sound, wait until it
stops before completely
removing the cap.
Automotive fuels can
cause serious injury or
death if misused or mishandled.
