Mercury Sable 1999 - Manual (Page 115)

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:
• Use 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.
• Anticipate 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.
