2002 Mercury Grand Marquis tow

Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage.
VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
²Base Curb Weight:Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include occupants or
aftermarket equipment.
²Payload:Combined maximum allowable weight of cargo, occupants
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
²GVW (Gross Vehicle Weight):Base curb weight plus payload
weight. The GVW is not a limit or a specification.
²GVWR (Gross Vehicle Weight Rating):Maximum permissable total
weight of the base vehicle, occupants, optional equipment and cargo.
The GVWR is specific to each vehicle and is listed on the Safety
Certification Label on the driver's door pillar.
²GAWR (Gross Axle Weight Rating):Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
Safety Certification Label on the driver's door pillar.
²GCW (Gross Combined Weight):The combined weight of the
towing vehicle (including occupants and cargo) and the loaded trailer.
²GCWR (Gross Combined Weight Rating):Maximum permissable
combined weight of the towing vehicle (including occupants and
cargo) and the loaded trailer.
²Maximum Trailer Weight Rating:Maximum weight of a trailer the
vehicle is permitted to tow. The maximum trailer weight rating is
determined by subtracting the vehicle curb weight for each
engine/transmission combination, any required option weight for trailer
towing and the weight of the driver from the GCWR for the towing
vehicle.
²Maximum Trailer Weight:Maximum weight of a trailer the loaded
vehicle (including occupants and cargo) is permitted to tow. It is
determined by subtracting the weight of the loaded trailer towing
vehicle from the GCWR for the towing vehicle.
²Trailer Weight Range:Specified weight range that the trailer must
fall within that ranges from zero to the maximum trailer weight rating.

Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle's GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.
The Certification Label, found on the inside pillar of the driver's door,
lists several important vehicle weight rating limitations. Before adding
any additional equipment, refer to these limitations. If you are adding
weight to your vehicle, always ensure that the weight of occupants, cargo
and equipment being carried is within the weight limitations that have
been established for your vehicle including both gross vehicle weight and
front and rear gross axle weight rating limits. Under no circumstance
should these limitations be exceeded.
Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle and/or personal injury.
The weight of your loaded trailer should not exceed 907 kg (2 000 lbs).
The GCW of your vehicle and trailer should not exceed 2 993 kg (6 600 lbs).
TRAILER TOWING
Your vehicle is classified as a light duty towing vehicle. Do not tow a
trailer until your vehicle has been driven at least 3 200 km (2 000 miles).
Towing a trailer places an additional load on your vehicle's engine,
transmission, brakes, tires and suspension. Inspect these components
carefully after towing.
Your loaded trailer should weigh no more than 907 kg (2 000 lbs.).
Do not exceed the GVWR or the GAWR specified on the
certification label.

Towing trailers beyond the maximum recommended gross trailer
weight could result in engine damage, transmission/axle damage,
structural damage, loss of control, and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer, and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that 10% of
the total weight of the trailer is on the tongue.
Safety chains
Always connect the trailer's safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer's safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer's
specifications. The trailer brakes must meet local and Federal
regulations.
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
When towing a trailer:
²Ensure that you turn off your speed control. The speed control may
shut off automatically when you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations for towing a trailer.
²Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
²Anticipate stops and brake gradually.
Exceeding the GCWR rating may cause internal transmission
damage and void your warranty coverage.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your scheduled maintenance guide for
more information.
Trailer towing tips
²Practice 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.
²Allow more distance for stopping with a trailer attached.
²If 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.
²The trailer tongue weight should be 10% of the loaded trailer weight.
²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) and increase idle speed. This aids engine
cooling and air conditioner efficiency.
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval:

²do not allow the static water level to rise above the bottom edge of
the rear bumper.
²do 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.
²Place the transmission in N (Neutral).
²Maximum speed is 56 km/h (35 mph).
²Maximum 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.
