2017 FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS parking brake

The anti-lock braking system will not
eliminate the risks when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
PARKING BRAKE WARNING
Always set the parking brake fully
and make sure the transmission
selector lever is placed in park (P).
Failure to set the parking brake and engage
park could result in vehicle roll-away,
property damage or bodily injury. Turn the
ignition to the lock position and remove
the key whenever you leave your vehicle. Apply the parking brake whenever your
vehicle is parked.
•
For vehicles equipped with a foot
operated parking brake, press the pedal
downward to set the parking brake.
• For vehicle equipped with a hand
operated parking brake, pull the
parking brake lever up to set the
parking brake. The brake warning lamp in the
instrument cluster illuminates
when the ignition is turned on
and the parking brake is applied.
The parking brake is not recommended to
stop a moving vehicle. However, if the
normal brakes fail, the parking brake can
be used to stop your vehicle in an
emergency. Your vehicle's stopping
distance will increase greatly and the
handling of your vehicle will be adversely
affected. To release the parking brake:
•
For vehicles equipped with a foot
operated parking brake, pull the
parking brake release lever.
• For vehicles equipped with a hand
operated parking brake, push the
parking brake lever down.

Trailer Brakes
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. Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Separate functioning brake systems
are required for safe control of towed
vehicles and trailers weighing more
than 1500 pounds (680 kilograms)
when loaded.
Trailer Lamps
WARNING
Never connect any trailer lamp wiring
to the vehicle's tail lamp wiring; this
may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required. Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, direction indicators and hazard lights
are working. Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (P) to aid engine and
transmission cooling and to help air
conditioning performance.
• Switch 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.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.

2. Set your vehicle parking brake.
3. Place the automatic transmission in
park (P).
4. Place wheel chocks in the front and back of the trailer wheels. (Chocks not
included with vehicle.)
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer 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 anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required. TOWING THE VEHICLE ON
FOUR WHEELS
Emergency Towing WARNING
If your vehicle has a steering wheel
lock make sure the ignition is in the
accessory or on position when being
towed. If your vehicle becomes inoperable
(without access to wheel dollies,
car-hauling trailer, or flatbed transport
vehicle), it can be flat-towed (all wheels
on the ground, regardless of the powertrain
and transmission configuration) under the
following conditions:
•
Your vehicle is facing forward for
towing in a forward direction.
• Place the transmission in position N. If
you cannot move the transmission into
N
, you may need to override it.
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).
