2019 FORD F650/750 Owners Manual

If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Press the switch again to enable the
traction control system.
System Indicator Light
Note:
If the traction control light does not
flash during a traction control event or stays
illuminated, the system is not functioning
properly. Take your vehicle to an authorized
dealer for service.
During traction control operation, the
traction control light flashes rapidly and
the engine does not rev-up when you press
further on the accelerator. This is normal
and is no reason for concern.
When traction control is disabled, the
traction control light illuminates and
flashes slowly.

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It's always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator's ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system automatically turns on each
time you switch the ignition on. If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
Vehicles With: Air Brakes
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes rapidly.
• Your vehicle slows down.
• Reduced engine power.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s motion and the rate at which it
changes by applying the brakes to one or
more wheels individually.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin.
See
Using Traction Control (page 133).

USING STABILITY CONTROL
The system automatically turns on each
time you switch the ignition on.
You cannot switch the stability control and
roll stability control systems off, but when
you shift into reverse (R), the systems
deactivate.
You can switch the traction control system
off or on. See Traction Control (page 133).
Limitations of the Stability System
Stability Control effectiveness may be
greatly reduced if: •
Your load shifts due to improper
retention, accident damage or the
inherently mobile nature of some loads,
for example, hanging meat, live
animals or partially laden tankers.
• Your vehicle or load has an unusually
high or off-set center of gravity (CG).
• Your brakes are not properly adjusted
or maintained.
• One side of your vehicle drops off the
pavement at an angle that is too great
to be counteracted by a reduction in
speed.
To Maximize the Effectiveness Of
Stability Control
• Make sure that the weight of your load
is evenly distributed, from front to back,
side to side and you secure it properly
at all times.
• Exercise extreme caution at all times
while driving and avoid sharp turns,
sudden steering inputs or abrupt lane
changes at high speeds, particularly if:
•Hauling loads that can shift.
• Your vehicle or load has a high or
off-set center of gravity when
loaded.
• You are towing doubles or triples.
ESC Usage with Tractor/Trailer
The ESC system is designed to work with
trailer air brake systems. We do not
recommend its use with any other trailer
brake system.
ESC and Towing with Non-tractor
Trucks (Straight or Kick-up Frame)
Non-tractor Trucks (Straight or Kick-up
Frame) with air brake ESC, should not be
used for towing any type of trailer.

Chassis Modifications
Stability Control is specifically calibrated
and validated only for your vehicle's
original configuration. If you alter your
vehicle's chassis components, for example,
a wheel base extension or reduction, tag
axle addition or removal, a major body
change such as conversion of a tractor into
a truck. Ford Motor Company is not
responsible for the performance of the
stability control system if you modify any
major components such as axle,
suspension or steering system.

PRINCIPLE OF OPERATION
Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal. You can use cruise
control when your vehicle speed is greater
than 20 mph (30 km/h).
USING CRUISE CONTROL WARNING:
Do not use cruise
control on winding roads, in heavy traffic
or when the road surface is slippery. This
could result in loss of vehicle control,
serious injury or death. WARNING:
When you are going
downhill, your vehicle speed could
increase above the set speed. The
system does not apply the brakes.
To help the system to maintain the set
speed when going downhill, downshift to
a lower gear.
Your vehicle speed could decrease below
the set speed when driving uphill.
Note: The system cancels if your vehicle
speed drops below 10 mph (16 km/h) under
the set speed when driving uphill. The cruise controls are on the steering
wheel. See
Cruise Control (page 47).

STEERING
To help prevent damage to the power
steering system:
•
Do not hold the steering wheel at its
furthest turning points for more than
three to five seconds when the engine
is running.
• Avoid continuously steering back and
forth with elevated engine RPM as this
may overheat the system. If trying to
free a stuck vehicle, pause between
attempts to allow the power steering
system to cool or seek assistance.
Typical steering and driving maneuvers
allow the system to cool.
• Do not operate the vehicle if the power
steering pump fluid level is below the
MIN mark on the reservoir.
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
If the power steering system breaks down
or if you switch off the engine, you can
steer the vehicle manually, but it takes
more effort.
Operating the steering system excessively
at an elevated engine RPM (>1200 rpm)
for more than 2 minutes can result in
steering system damage from overheating.
Move the steering wheel to the full left
position then full right position at idle
speed, or stop using the system for 2
minutes to allow the system to cool down. If the power steering system exhibits heavy
or uneven efforts, check for the following
before seeking service from your dealer:
•
An improperly inflated tire.
• Overloading of front suspension.
• Uneven vehicle loading.
• Binding suspension components.
If the power steering system wanders or
pulls, check for:
• An improperly inflated tire.
• Uneven vehicle loading.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
• High crosswinds.
If you service or replace any steering
components, install new fasteners. Many
fasteners have thread adhesive coatings,
or have prevailing torque features, which
you cannot re-use. Do not re-use a bolt or
nut. Torque fasteners to specifications.
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull.

LOAD LIMIT
WARNING: Do not exceed
the GVWR or the GAWR
specified on the Safety
Compliance Certification Label. WARNING:
Do not use
replacement tires with lower
load carrying capacities than the
original tires 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. WARNING:
Exceeding any
vehicle weight rating limitation
could result in serious damage
to the vehicle and/or personal
injury.
Every vehicle manufactured by
Ford Motor Company is supplied
with information on the Safety
Compliance Certification Label,
located on either the B-pillar or
the driver ’s door edge, listing the
maximum loading for the vehicle
(GVWR), and its axle systems
(GAWR) at the tire to ground
interface. Example only:
Under no circumstances should
your vehicle be loaded in excess
of the GVWR or GAWR. It is the
operator
’s responsibility to ensure
that neither the axle capacities,
spring capacities, tire capacities
nor the vehicle rated GVWR is
exceeded.
Unloaded or Lightly Loaded
Vehicles WARNING:
When
operating empty or lightly
loaded, sudden or hard braking
may induce wheel lockup with
loss of vehicle control and the
possibility of accident and
serious injury, especially on wet
or slippery road surfaces.
The braking system has been
designed to safely stop your
vehicle when fully loaded to its
GVWR.
