brake booster FORD E-450 2019 Owners Manual

Pregnant women should always wear their
seatbelt. Position the lap belt portion of a
combination lap and shoulder belt low
across the hips below the belly and worn
as tight as comfort allows. Position the
shoulder belt to cross the middle of the
shoulder and the center of the chest.
Seatbelt Locking Modes
WARNING: If your vehicle is
involved in a crash, have the seatbelts
and associated components inspected
as soon as possible. Failure to follow this
instruction could result in personal injury
or death.
All safety restraints in the vehicle are
combination lap and shoulder belts. The
driver seatbelt has the first type of locking
mode. The front outboard passenger
seatbelt has both types of locking modes
described as follows:
Vehicle Sensitive Mode
This is the normal retractor mode, which
allows free shoulder belt length
adjustment to your movements and
locking in response to vehicle movement.
For example, if the driver brakes suddenly
or turns a corner sharply, or the vehicle
receives an impact of about
5 mph
(8 km/h) or more, the combination
seatbelts lock to help reduce forward
movement of the driver and passengers.
In addition, the retractor is designed to lock
if you pull the webbing out too quickly. If
the seatbelt retractor locks, slowly lower
the height adjuster to allow the seatbelt
to retract. If the retractor does not unlock,
pull the seatbelt out slowly then feed a small length of webbing back toward the
stowed position. For rear seatbelts, recline
the rear seat backrest or push the seat
backrest cushion away from the seatbelt.
Feed a small length of webbing back
toward the stowed position.
Automatic Locking Mode
In this mode, the shoulder belt
automatically pre-locks. The belt will still
retract to remove any slack in the shoulder
belt. The automatic locking mode is not
available on the driver seatbelt.
When to Use the Automatic Locking
Mode
Use this mode any time a child safety seat,
except a booster, is installed in the
passenger front seating position. See
Child Safety
(page 17).
How to Use the Automatic Locking
Mode 1. Buckle the combination lap and
shoulder belt.
2. Grasp the shoulder portion and pull downward until the entire belt is pulled
out.
3. Allow the belt to retract. As the belt retracts, you will hear a clicking sound.
This indicates the seatbelt is now in the
automatic locking mode.

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. See Cleaning the Wheels
(page 165).
Note: Indicators vary depending on region. See
Warning Lamps and
Indicators (page 54). 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. Switch the engine off, shift the
transmission into park (P), 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 turns on if you apply
the brake pedal, or if you switch the ignition
to the on position.
The sound of the pump operating may be
heard by the driver. 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
removal of the vehicle from the roadway.
Note:
For vehicles with the Hydromax
system operating under normal conditions,
the noise of the fluid flowing through the
booster may be heard whenever you apply
the brake. This condition is normal. Vehicle
service is not required.
If braking performance or pedal response
becomes very poor, even when you
strongly press the pedal, it may indicate
the presence of air in the hydraulic system
or leakage of fluid. Stop the vehicle safely
as soon as possible and seek service
immediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
