When backing down a ramp during boat launching or retrieval:
• 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 vehicle components:
• causing internal damage to the components.
• affecting driveability, emissions and reliability.
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.
RECREATIONAL TOWING (ALL WHEELS ON THE GROUND)
An example of recreational towing would be towing your vehicle behind
a motorhome. Follow these guidelines if you have the need for
recreational towing your vehicle with all four wheels on the ground.
These guidelines are designed to ensure that your transmission is not
damaged.
2WD vehicles (with automatic transmissions):
• Place the transmission in N (Neutral)
• Maximum speed is 56 km (35 mph)
• Maximum distance is 80 km (50 miles)
If a distance of 80 km (50 miles) or a speed of 56 km (35 mph) must be
exceeded, the drive shaft will have to be removed before the vehicle is
towed.
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.
Vehicles equipped with Control Trac four-wheel drive system:
Vehicles equipped with the Control Trac four-wheel drive system cannot
be towed with any wheels on the ground. See your local dealer if you
must flat-tow a vehicle equipped with the Control Trac four-wheel drive
system.

• Have the items listed in your scheduled maintenance guide performed
according to the specified schedule.
The scheduled maintenance items listed in the scheduled maintenance
guide are essential to the life and performance of your vehicle and to its
emissions system.
If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Illumination of the “ Check Engine ” light, charging system warning light
or the temperature warning light, fluid leaks, strange odors, smoke or
loss of engine power, could indicate that the emission control system is
not working properly.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle ’ s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult your Warranty Guide for complete emission warranty
information.
On board diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine ’ s
emission control system. This system is commonly known as the On
Board Diagnostics System (OBD-II). This OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists the
service technician in properly servicing your vehicle. When the Check
Engine/Service Engine Soon light illuminates, the OBD-II system has
