do not allow the static water level to rise above the bottom edge of
the rear bumper.
do not allow waves to break higher than 15 cm (6 inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions, reliability and
causing internal transmission damage.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
Disconnect the wiring to the trailer before backing the trailer into the
water. Reconnect the wiring to the trailer after the trailer is removed
from the water.

RECREATIONAL TOWING (ALL WHEELS ON THE GROUND)

Follow these guidelines for your specific powertrain combination to tow
your vehicle with all four wheels on the ground (such as behind a
recreational vehicle).
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.

All Rear Wheel Drive (RWD) vehicles

This applies to all cars and 4x2 trucks/sport utilities with rear wheel
drive capability.
An example of recreational towing is towing your vehicle behind a
motorhome. The following recreational towing guidelines are designed to
ensure that your transmission is not damaged.
Place the transmission in N (Neutral).
Maximum speed is 56 km/h (35 mph).
Maximum distance is 80 km (50 miles).
If a distance of 80 km (50 miles) or a speed of 56 km/h (35 mph) must
be exceeded, you must disconnect the driveshaft. Ford recommends the
driveshaft be removed/installed only by a qualified technician. See your
local dealer for driveshaft removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid loss, damage to the driveshaft and internal
transmission components.
