Tires, Wheels and Loading Driving while you tow When towing a trailer: • To ensure proper "break-in" of powertrain components, do not trailer tow during the first 1,000 miles (1,600 km) of a new vehicle. • To ensure proper "break-in" of powertrain components during the first 500 miles (800 km) of trailer towing, drive no faster than 70 mph (113 km/h) with no full throttle starts. • Turn off the speed control. The speed control may shut off automatically when you are towing on long, steep grades. • Consult your local motor vehicle speed regulations for towing a trailer. • To eliminate excessive shifting, use a lower gear. This will also assist in transmission cooling. For additional information, refer to Automatic transmission operation in the Driving chapter. • Anticipate stops and brake gradually. • Do not exceed the GCWR rating or transmission damage may occur. Servicing after towing If you tow a trailer for long distances, your vehicle will require more frequent service intervals. Refer to your scheduled maintenance information for more information. Trailer towing tips • Practice turning, stopping and backing up before starting on a trip to get the feel of the vehicle trailer combination. When turning, make wider turns so the trailer wheels will clear curbs and other obstacles. • Allow more distance for stopping with a trailer attached. • If you are driving down a long or steep hill, shift to a lower gear. Do not apply the brakes continuously, as they may overheat and become less effective. • The trailer tongue weight should be 10-15% of the loaded trailer weight. • If you will be towing a trailer frequently in hot weather, hilly conditions, at GCWR, or any combination of these factors, consider refilling your rear axle with synthetic gear lube if not already so equipped. Refer to the Maintenance and Specifications chapter for the lubricant specification. Remember that regardless of the rear axle lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a new vehicle, and that the first 500 miles (800 km) of towing be done at no faster than 70 mph (113 km/h) with no full throttle starts. 166 2009 Grand Marquis (grn) Owners Guide (own2002), 2nd Printing USA (fus)

Driving while you tow
When towing a trailer:
To ensure proper “break-in” of powertrain components, do not trailer
tow during the first 1,000 miles (1,600 km) of a new vehicle.
To ensure proper “break-in” of powertrain components during the first
500 miles (800 km) of trailer towing, drive no faster than 70 mph
(113 km/h) with no full throttle starts.
Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
Consult your local motor vehicle speed regulations for towing a trailer.
To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. For additional information, refer to
Automatic
transmission operation
in the
Driving
chapter.
Anticipate stops and brake gradually.
Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your
scheduled maintenance
information
for more information.
Trailer towing tips
Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
Allow more distance for stopping with a trailer attached.
If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
The trailer tongue weight should be 10–15% of the loaded trailer
weight.
If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to the
Maintenance and Specifications
chapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 km/h) with no full throttle starts.
