1999 Mercury Sable maintenance

Do not connect a trailer's hydraulic brake
system directly to your vehicle's brake
system. Your vehicle may not have enough braking
power and your chances of having a collision
greatly increase.
The braking system of the tow vehicle is rated for
operation at the GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles.
Make sure your trailer lamps conform to local and
Federal regulations. See your dealer or trailer rental
agency for proper instructions and equipment for
hooking up trailer lamps.
Driving while you tow
Do not drive faster than 88 km/h (55 mph) when
towing a trailer. Do not drive faster than 72 km/h
(45 mph) with any weight on the trailer while
towing on a hot day or in hilly country.
Speed control may shut off if you are towing on
long, steep grades.
When towing a trailer:
²Use D (Drive) or a lower gear when towing up or
down steep hills. This will eliminate excessive
downshifting and upshifting for optimum fuel
economy and transaxle cooling.
²Anticipate stops and brake gradually.
Servicing after towing
If you tow a trailer for long distances, your vehicle
will require more frequent service intervals. Refer to
your maintenance guide and or service guide for
more information.

Adding engine oil
1. Check the engine oil. For instructions, refer to
Checking 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.

Engine oil and filter recommendations
Look for this
certification mark.
Ford oil specification is WSS-M2C153-G.
Use SAE 5W-30 motor oil certified for gasoline
engines by the American Petroleum Institute.
Do not use supplemental engine oil additives, oil
treatments or engine treatments. They are
unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your
warranty.
Change your engine oil and filter 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,
startup engine noises or knock may be experienced.
