2022 FORD E-450 brake fluid

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 your vehicle as
soon as it is safe to do so. Have the system
checked as soon as possible.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does 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.
Note: If the system activates, the brake
pedal could pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal. PARKING BRAKE WARNING: Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death.
Apply the parking brake whenever you park
your vehicle.
• For vehicles with a foot operated
parking brake, press the pedal down.
• For vehicles with a hand operated
parking brake, pull the parking brake
lever up. It illuminates when you switch
the ignition on and apply the
parking brake. It also illuminates
momentarily when you switch
the ignition on to confirm the
lamp is functional. If it does not
illuminate when you switch the ignition on
or begins to flash at any time, have the
system checked by an authorized dealer.
If it illuminates when your vehicle is
moving, make sure you disengage the
parking brake.
If the parking brake is disengaged, this
indicates a low brake fluid level or a brake
system fault. Have your vehicle checked
as soon as possible.
To release the parking brake:
• For vehicles with a foot operated
parking brake, pull the parking brake
release lever.
• For vehicles with a hand operated
parking brake, push the parking brake
lever down.

Checking Automatic Transmission
Fluid
For scheduled intervals of the fluid checks
and changes, See Scheduled
Maintenance (page 251). Your
transmission does not consume fluid.
However, if the transmission is not working
properly, for example, if the transmission
slips or shifts slowly, or if you notice some
sign of fluid leakage, check the fluid level
as soon as possible.
Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle until it is at normal
operating temperature, approximately
19 mi (30 km). Verify that the transmission
fluid temperature gauge on the instrument
cluster is within normal range.
1. Drive the vehicle
19 mi (30 km) until it
reaches normal operating temperature.
2. Park the vehicle on a level surface and
engage the parking brake.
3. With the engine running, parking brake
engaged and your foot on the brake
pedal, move the gearshift lever through
all of the gear ranges. Allow sufficient
time for each gear to engage.
4. Put the transmission in park (P) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry, lint free rag.
6. Install the dipstick, fully seating it in the
filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be in the
designated area for normal operating
temperature or ambient temperature. Low Fluid Level
Do not drive the vehicle if there is no
indication of fluid on the dipstick and the
ambient temperature is above
50°F
(10°C).
Correct Fluid Level Drive the vehicle
19 mi (30 km) or until it
reaches normal operating temperature.
Check the fluid at the normal operating
temperature of
196°F (91°C) to 215°F
(102°C) on a level surface.

BRAKE FLUID CHECK
WARNING: Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death. WARNING:
Do not allow the fluid
to touch your skin or eyes. If this
happens, rinse the affected areas
immediately with plenty of water and
contact your physician. WARNING:
The brake system
could be affected if the brake fluid level
is below the MIN mark or above the MAX
mark on the brake fluid reservoir. 1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative
to the
MIN and the MAX marks on the
reservoir.
Note: If the brake fluid level is between the
MIN
and the MAX marks on the reservoir, it
is acceptable.
Note: If the brake fluid level is below the
MIN
mark or above the MAX mark, have
your vehicle checked as soon as possible.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our
specifications. See
Capacities and
Specifications (page 223).
Brake Fluid Service Interval
Brake fluid absorbs water over time which
degrades the effectiveness of the brake
fluid. Change the brake fluid at the
specified intervals to prevent degraded
braking performance.

For detailed interval information, see
Scheduled Maintenance in your Owner's
Manual or your local maintenance guide.
POWER STEERING FLUID
CHECK
WARNING: A fluid level between
the MAX and MIN lines is within the
normal operating range and there is no
need to add fluid. A fluid level not in the
normal operating range could
compromise the performance of the
system. WARNING:
For E-350 and E-450
vehicles with the Hydro-Boost Brake
System, do not press the brake pedal
after the engine has been turned off.
Pressing the brake pedal after the engine
has been turned off will give a false
power steering fluid level reading.
Only use fluid that meets Ford
specifications. See
Hydraulic Power
Steering Fluid Capacity and
Specification
(page 233).
To top up the power steering fluid level do
the following.
1. Start the engine and let it run until it reaches normal operating temperature.
2. Make sure the fluid is within the
MIN
and MAX range.
3. If the fluid level is low, add fluid to be within the
MIN and MAX range. Do not
overfill.
4. While the engine idles, turn the steering
wheel left and right several times.
5. Recheck the fluid level in the reservoir.
Note: Do not operate the vehicle with a low
power steering pump fluid level. CHANGING THE 12V BATTERY WARNING:
This vehicle may have
more than one battery. Removing the
battery cables from only one battery
does not disconnect your vehicle
electrical system. Make sure you
disconnect the battery cables from all
batteries when disconnecting power.
Failure to do so may cause serious
personal injury or property damage. WARNING:
Batteries normally
produce explosive gases which can
cause personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery, always
shield your face and protect your eyes.
Always provide correct ventilation. WARNING:
When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in
personal injury and damage to the
vehicle or battery. Lift the battery with a
battery carrier or with your hands on
opposite corners. WARNING:
Keep batteries out of
reach of children. Batteries contain
sulfuric acid. Avoid contact with skin,
eyes or clothing. Shield your eyes when
working near the battery to protect
against possible splashing of acid
solution. In case of acid contact with skin
or eyes, flush immediately with water for
a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed,
call a physician immediately.
