2021 FORD F-450 wheel

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.
• The Adaptive Steering system (if
equipped) automatically changes the
steering function to a fixed steering
ratio. See
Adjusting the Steering
Wheel (page 81).
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.
• Your vehicle slows down.
• Reduced 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 may 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 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 roll 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 227). Vehicle without stability control

The system turns on each time you switch
the ignition on.
You can switch the electronic stability
control and roll stability control portions
of the system off.
When you shift the transmission into

control switch on the instrument
panel to switch the systems off
or on.
You can independently switch off the
traction control portion of the system.

WHAT IS TRAIL CONTROL
WARNING: The system does not
control speed in low traction conditions
or extremely steep slopes. The system
is designed to be an aid and does not
relieve you of your responsibility to drive
with due care and attention. Failure to
follow this instruction could result in
personal injury. WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission.
Trail control lets you focus on steering
during low-speed and off-road use by
controlling your vehicle's acceleration and
braking.
You can use trail control under the
following speeds:
• 20 mph (31 km/h)
in two-wheel or
four-wheel drive high range.
• 10 mph (15 km/h)
in four-wheel drive
low range.
• 5 mph (8 km/h)
in reverse (R).
You may hear a noise from the anti-lock
brake system pump motor when you use
the system. This is normal.
SWITCHING TRAIL CONTROL
ON AND OFF Press the button.
The system switches off if you press the
button again or exceed 42 mph (68 km/h). SETTING THE TRAIL CONTROL
