2013 FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS light

Grade braking downshift mode is immediately exited if the Tow/Haul
mode is deactivated or if the accelerator pedal is depressed beyond a
minimum threshold.
To deactivate the tow/haul feature and return to normal driving mode,
press the button on the end of the gearshift lever. The TOW HAUL light
will no longer be illuminated.
When you shut-off and restart the engine, the transmission will
automatically return to normal D (Overdrive) mode (tow/haul off).
WARNING:Do not use the tow/haul feature when driving in icy
or slippery conditions as the increased engine braking can cause
the rear wheels to slide and the vehicle to swing around with the
possible loss of vehicle control.
3 (Third)
Transmission starts and operates in third gear only.
Used for improved traction on slippery roads. Selecting 3 (Third)
provides engine braking.
2 (Second)
Use 2 (Second) to start-up on slippery roads or to provide additional
engine braking on downgrades.

GENERAL INFORMATION
Note:Occasional brake noise is normal. If a metal-to-metal, continuous
grinding or continuous squeal sound is present, the brake linings may be
worn-out and should be inspected by an authorized dealer. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by an authorized dealer.
Note:Brake dust may accumulate on the wheels, even under normal
driving conditions. Some dust is inevitable as the brakes wear and does
not contribute to brake noise. Refer to theVehicle Carechapter for
wheel cleaning instructions.
Refer to theInstrument Clusterchapter for information on the
brake system warning light.
Wet brakes result in reduced braking efficiency. Gently press the brake
pedal a few times when driving from a car wash or standing water to dry
the brakes.
Brake Over Accelerator
In the event the accelerator pedal becomes stuck or entrapped, apply
steady and firm pressure to the brake pedal to slow the vehicle and
reduce engine power. If you experience this condition, apply the brakes
and bring your vehicle to a safe stop. Turn the engine off, shift to P
(Park) and apply the parking brake, and then inspect the accelerator
pedal for any interferences. If none are found and the condition persists,
have your vehicle towed to the nearest authorized dealer.
Hydraulic brake booster system (Hydroboost or Hydromax)
The Hydroboost and Hydromax systems receive fluid pressure from the
power steering pump to provide power assist during braking.
The Hydromax booster receives backup pressure from the reserve
system electric pump whenever the fluid in the power steering system is
not flowing. When the engine is off, the pump will turn on if the brake
pedal is applied, or if the ignition is turned to the on position.
The sound of the pump operating may be heard by the driver, but this is
a normal characteristic of the system.
The reserve system provides reduced braking power, so the vehicle
should be operated under these conditions with caution, and only to seek
service repair and remove the vehicle from the roadway.

TOWING A TRAILER
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.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components periodically during, and after, any towing operation.
Load Placement
To help minimize how trailer movement affects the vehicle when driving:
•Load the heaviest items closest to the trailer floor.
•Load the heaviest items so they are centered between the left and
right side trailer tires.
•Load the heaviest items above the trailer axles or just slightly forward
toward the trailer tongue. Do not allow the final trailer tongue weight
to go above or below 10–15% of the loaded trailer weight.
•Select a tow bar with the correct rise or drop. When both the loaded
vehicle and trailer are connected, the trailer frame should be level, or
slightly angled down toward the vehicle, when viewed from the side.
When driving with a trailer or payload, a slight takeoff vibration or
shudder may be present due to the increased payload weight. Additional
information regarding proper trailer loading and setting your vehicle up
for towing is noted underLoad limitin theLoad Carryingchapter and
in theRV & Trailer Towing Guide,available at your authorized dealer.
RECOMMENDED TOWING WEIGHTS
Note:Do not exceed the trailer weight for your vehicle configuration
listed in the chart below.
Note:Make sure to take into consideration trailer frontal area. Do not
exceed:
•60 feet
2(5.6 meters2) trailer frontal area.
Note:For high altitude operation, reduce the gross combined weight by
2% per 1000 feet (300 meters) starting at the 1000 foot (300 meter)
elevation point.

Hitches
Do not use a hitch that either clamps onto the bumper or attaches to the
axle. Distribute the trailer load so 10–15% of the total trailer weight is on
the tongue.
Weight-Distributing Hitch
When hooking-up a trailer using a weight-distributing hitch, always use
the following procedure:
1. Park the loaded vehicle (without the trailer) on a level surface.
2. Measure the height to the top of the vehicle front wheel opening on
the fender, this is H1.
3. Securely attach the loaded trailer to the vehicle without the
weight-distributing bars connected.
4. Measure the height to the top of the vehicle front wheel opening on
the fender a second time, this is H2.
5. Install and adjust the tension in the weight-distributing bars so that
the height of the vehicle’s front wheel opening on the fender is
approximately halfway between H1 and H2.
6. Check that the trailer is level or slightly nose down. If not, adjust the
ball height accordingly and repeat Steps 1 through 6.
7. Lock bar tension adjuster in place.
8. Check that the trailer tongue is securely attached and locked to the
hitch.
9. Install safety chains, lighting, and trailer brake controls as required
by law or the trailer manufacturer.
WARNING:Do not adjust a weight-distributing hitch to any
position where the rear bumper of the vehicle is higher than it
was before attaching the trailer. Doing so will defeat the function of the
weight-distributing hitch, which may cause unpredictable handling, and
could result in serious personal injury.
Safety Chains
Note:Never attach safety chains to the bumper.
Always connect the safety chains to the hook retainers of the vehicle
hitch.
To connect the safety chains, cross them under the trailer tongue and
allow enough slack for turning tight corners. Do not allow the chains to
drag on the ground.

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.
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 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 1,500 lb
(680 kg) when loaded.
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 the lamps.
Before Towing a Trailer
Practice turning, stopping and backing-up to get the feel of the
vehicle-trailer combination before starting on a trip. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
When Towing a Trailer
•Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 kilometers).
•Do not make full-throttle starts.
•Check your hitch, electrical connections and trailer wheel lug nuts
thoroughly after you have traveled 50 miles (80 kilometers).
•When stopped in congested or heavy traffic during hot weather, place
gearshift in P (Park) to aid engine and transmission cooling and to
help A/C performance.
•Turn off the speed control with heavy loads or in hilly terrain. The
speed control may turn off automatically when you are towing on
long, steep grades.

•Carry unnecessary weight (approximately 1 mpg [0.4 km/L] is lost for
every 400 lb [180 kg] of weight carried).
•Add particular accessories to your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski racks).
•Drive with the wheels out of alignment.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly. Never drive through water
that is higher than the bottom of
the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.
Note:Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause internal
transmission damage.
Note:Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal. Wet
brakes do not stop the vehicle as quickly as dry brakes.
