Lincoln 2013 MKZ Owner's Manual page 233

The braking system of the tow
vehicle is rated for operation at the
GVWR not GCWR.
Separate functioning brake
systems are required for safe
control of towed vehicles and
trailers weighing more than 1500
pounds (680 kilograms) when
loaded.
Trailer Lamps
Trailer lamps are required on most
towed vehicles. Make sure all running
lights, brake lights, turn signals and
hazard lights are working. Contact
your authorized dealer or trailer rental
agency for proper instructions and
equipment for hooking up the lamps.
Before Towing a Trailer
Practice turning, stopping and
backing-up to get the feel of the
vehicle-trailer combination before
starting on a trip. When turning, make
wider turns so the trailer wheels clear
curbs and other obstacles.
When Towing a Trailer
• Do not drive faster than 70 mph
(113 km/h) during the first 500
miles (800 kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical
connections and trailer wheel lug
nuts thoroughly after you have
traveled 50 miles (80 kilometers).
Towing
• When stopped in congested or
heavy traffic during hot weather,
place the gearshift in position P to
aid engine and transmission
cooling and to help A/C
performance.
• Turn off the speed control with
heavy loads or in hilly terrain. The
speed control may turn off
automatically when you are towing
on long, steep grades.
• Shift to a lower gear when driving
down a long or steep hill. Do not
apply the brakes continuously, as
they may overheat and become
less effective.
• If your transmission is equipped
with a grade assist or Tow/Haul
feature, use this feature when
towing. This provides engine
braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping
with a trailer attached. Anticipate
stops and brake gradually.
