Ford Crown Victoria (2011 year). Manual — part 42

WARNING: Do not exceed the GVWR or the GAWR specified on
the certification label.

WARNING: Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could

result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.

Preparing to tow

Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. Contact your authorized dealer or a
reliable trailer dealer as soon as possible if you require assistance.

Hitches

Do not use a hitch that clamps onto the vehicle’s bumper; use a
load-carrying hitch. You must distribute the load in your trailer so that
10–15% 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.

WARNING: 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 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 trailer lamps.

Driving while you tow

When towing a trailer:
• Do not drive faster than 70 mph (113 km/h) during the first 500 miles

(800 km) of trailer towing and don’t make full-throttle starts.

• Turn off the speed control. The speed control may shut off

automatically when you are towing on long, steep grades.

• Use a lower gear to eliminate excessive shifting and assist in

transmission cooling. For additional information, refer to Automatic
transmission operation in the Driving chapter.

• Allow more distance for stopping with a trailer attached; anticipate

stops and brake gradually.

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.

• To aid in engine/transmission cooling and A/C efficiency during hot

weather while stopped in traffic, place the gearshift lever in P (Park).

• After you have traveled 50 miles (80 km), thoroughly check your

hitch, electrical connections and trailer wheel lug nuts.

• 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.

• 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.

• Vehicles 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

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.

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 6 in (15 cm) 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

Follow these guidelines if you have a need for recreational (RV) towing.
An example of recreational towing would be towing your vehicle behind
a motor home.

In case of a roadside emergency with a disabled vehicle, please refer to
Wrecker towing in the Roadside Emergencies chapter.

These guidelines are designed to prevent damage to your vehicle.

Do not tow your vehicle with any wheels on the ground, as vehicle or
transmission damage may occur. It is recommended to tow your vehicle
with all four (4) wheels off the ground such as when using a car-hauling
trailer. Otherwise, no recreational towing is permitted.

STARTING

Positions of the ignition

1. Off— shuts off the engine and all
accessories/locks the gearshift lever
and allows key removal.

2. Accessory— allows the electrical
accessories such as the radio to
operate while the engine is not
running.

3. On— all electrical circuits
operational. Warning lights
illuminated. Key position when
driving.
4. Start— cranks the engine. Release the key as soon as the engine
starts.

Preparing to start your vehicle
Engine starting is controlled by the powertrain control system.
This system meets all Canadian interference-causing equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, avoid pressing the accelerator
before or during starting. Only use the accelerator when you have
difficulty starting the engine. For more information on starting the
vehicle, refer to Starting the engine in this chapter.

WARNING: Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,

creating the risk of fire or other damage.

WARNING: 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.

WARNING: Do not start your vehicle in a closed garage or in
other enclosed areas. Exhaust fumes can be toxic. Always open

the garage door before you start the engine. See Guarding against
exhaust fumes in this chapter for more instructions.
