•towing a trailer up or down steep hills.
•additional engine downhill braking is desired. If towing a trailer, refer
toDriving while you towin theTrailer towingsection.
To return to
(Overdrive) mode, press the transmission control switch
(TCS). The TCIL (the word OFF) will no longer be illuminated.
Each time the vehicle is started, the transmission will automatically
return to normal overdrive mode.
Every time the vehicle is shut off and restarted, you must press the
transmission control switch to cancel overdrive operation if driving in
overdrive is not desired.
2 (Second)
Use 2 (Second) to start-up on
slippery roads or to provide
additional engine braking on
downgrades.
1 (First)
Use 1 (Low) to provide maximum
engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
(Overdrive). Selecting 1 (Low) at
higher speeds causes the transmission to shift to a lower gear, and will
shift to 1 (Low) after vehicle decelerates to the proper speed.
Forced Downshifts
To gain acceleration in
(Overdrive) or Drive (O/D OFF) when
passing another vehicle, push the accelerator to the floor. The
transmission will downshift to the appropriate gear: third, second or first
gear.
VEHICLE LOADING
Your vehicle’s load capacity is designed by weight, not volume, so you
cannot necessarily use all available space with large or heavy loads.
Maximum safe vehicle weights as well as tire, rim sizes and inflation
pressures are specified for your vehicle on the Safety Compliance
Certification Label. A Certification Label was supplied by Ford Motor
Company to the Motorhome Manufacturer. The manufacturer uses this
Driving
33

information and supplies a Certification Label which is located inside the
vehicle to the left of the driver.
Before loading a vehicle, familiarize yourself with the following terms:
•Base Curb Weight:Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include passengers or
aftermarket equipment.
•Payload:Combined maximum allowable weight of cargo, passengers
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
•GVW (Gross Vehicle Weight):Base curb weight plus payload
weight. The GVW is not a limit or a specification.
•GVWR (Gross Vehicle Weight Rating):Maximum total weight of
the base vehicle, passengers, optional equipment and cargo. The
GVWR is specific to each vehicle and is listed on the Certification
Label, located near the driver’s seat or on the driver’s door pillar.
•GAWR (Gross Axle Weight Rating):Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
Certification Label, located near the driver’s seat or on the driver’s
door pillar.
•GCWR (Gross Combined Weight Rating):Maximum combined
weight of towing vehicle (including passengers and cargo) and the
trailer.
•Maximum Trailer Weight Rating:Maximum weight of a trailer the
loaded vehicle (including passengers and cargo) 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.
•Trailer 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 weight capacities than the
originals because they may lower the vehicle’s GVWR and GAWR
Driving
34

limitations. Replacement tires with a higher weight limit than the
originals do not increase the GVWR and GAWR limitations.
Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum gross combined weight rating (GCWR)
chart to find the maximum GCWR for your type engine and rear axle
ratio.
2. Weigh your vehicle as you customarily operate the vehicle without
cargo. To obtain correct weights, try taking your vehicle to a shipping
company or an inspection station for trucks.
3. Subtract your loaded vehicle weight from the maximum GCWR on the
following charts. This is the maximum combined cargo and trailer weight
your vehicle can carry/tow and must fall below the maximum shown
under maximum trailer weight on the chart. Refer to the definition of
Maximum Trailer Weight below Vehicle Loading in this chapter to
determine the maximum trailer weight permitted for a loaded vehicle.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following chart:

For high altitude operation reduce GCW by 2% per 300 meters (1 000
ft) elevation. To determine the maximum trailer weight designed for
your particular vehicle as equipped, follow the sectionCalculating the
load your vehicle can carry/towearlier in this chapter.
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
You must distribute the load in your trailer so that 10 – 15% of the total
weight of the trailer is on the tongue.
Load equalizing hitch
When hooking up a trailer using a load equalizing hitch, always use the
following procedure:
1. Park the unloaded vehicle on a level surface. With the ignition on and
all doors closed, allow the vehicle to stand for several minutes so that it
can level.
2. Measure the height of a reference point on the front and rear bumpers
at the center of the vehicle.
3. Attach the trailer to the vehicle and adjust the hitch equalizers so that
the front bumper height is within 0–13 mm (
12inch) of the reference
point. After proper adjustment, the rear bumper should be no higher
than in Step 2.
Adjusting an equalizing hitch so the rear bumper of the vehicle
is lower or higher than it was unloaded will defeat the function
of the load equalizing hitch and may cause unpredictable handling.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle. 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 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.
Driving
36

The towing vehicle braking system is rated for operation at the GVWR,
not the GCWR.
Separate functioning brake systems are required for safe control of
towed vehicles and trailers weighing more than 680 kg (1 500 lbs) when
loaded.
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
Do not drive faster than 88 km/h (55 mph) when towing a trailer.
Speed control may shut off if you are towing on long, steep grades.
When towing a trailer:
•Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
•Anticipate stops and brake gradually.
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
•Practice turning, stopping and backing up in an area 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.
•The trailer tongue weight should be 10% of the loaded trailer weight.
•After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•When 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.
Driving

•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.
DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine’s air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims (for cars).
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transmission/transmission
vent tube is submerged may allow water into the transmission
and cause internal transmission damage.
