2021 FORD F650/750 Owners Manual

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
Note:
The system does not apply the brakes
when vehicle speed is above 25 mph
(40 km/h).
USING TRACTION CONTROL -
VEHICLES WITH: AIR BRAKES WARNING:
The stability and
traction control light illuminates steadily
if the system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead
to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death. Press the TCS Off button on the
instrument panel to enable the
mud/snow mode.
This is beneficial when your vehicle is stuck
in snow or on a slippery road surface. This
mode allows wheel spin to dig your vehicle
out and allows you to rock your vehicle. Press the switch again to select standard
traction control. The system automatically
selects standard traction control at the
next ignition cycle.
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.
In Mud/Snow mode, the TCS OFF light
illuminates on the instrument cluster. If a
traction event occurs in either mode, the
Stability Control and Traction Control light
flashes rapidly.
USING TRACTION CONTROL -
VEHICLES WITH: HYDRAULIC
BRAKES WARNING:
Aggressive driving in
any road conditions can cause you to
lose control of your vehicle increasing
the risk of severe personal injury or
property damage. The traction control
activating is an indication that at least
some of the tires have exceeded their
ability to grip the road; this may lead to
an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death. If you experience a severe
road event, slow down
.
The system turns on each time you switch
the ignition on.

switch the system off or on.
If your vehicle is stuck in mud or snow,
switching traction control off is beneficial
as this allows the wheels to spin.
Press the button again to switch the
traction control system on.
System Indicator Light
Note: If the traction control light does not
flash during a traction control event or stays
on, the system is not operating. Have the
system checked as soon as possible.
During a traction control event, the traction
control light rapidly flashes. Pressing
further on the accelerator does not cause
the engine to rev higher. This is normal and
is no reason for concern.
When the system turns the traction control
off, the OFF light illuminates on the
instrument cluster. If a traction event
occurs in either mode, the stability control
and traction control light rapidly flashes.

BRAKES
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 turns on each time you switch
the ignition on.
If a fault occurs in either the stability
control or the traction control system, the
following conditions are possible:
• The stability and traction control light
illuminate.
• The stability control and traction
control systems are not maintaining
traction of the wheels.
If a driving condition activates either the
stability control or the traction control
system, the following conditions are
possible:
• The stability and traction control light
flash.
• Your vehicle slows down.
• The system reduces engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal could move as the system
applies higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system assists in preventing skids or
lateral slides by applying the brakes to one
or more of the wheels individually and, if
necessary, decreases engine power.

•
The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
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 142). Vehicle without stability control

•
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.
