Ford F-350 (2024 year). Manual in english

Failure to perform active or manual
regeneration when instructed could result
in a clogged diesel particulate filter. If the
diesel particulate filter fills beyond the
regeneration threshold, your vehicle
disables the ability for active and manual
regeneration. This could result in
irreversible damage your vehicle Warranty
may not cover.

DIESEL PARTICULATE FILTER
REQUIREMENTS

The diesel particulate filter on your vehicle
requires periodic regeneration to maintain
its correct function.

If your journeys meet one of the following
conditions:
•

You drive only short distances.

•

You frequently switch the ignition on
and off.

•

Your journeys contain a high level of
acceleration and deceleration.

You must carry out occasional trips with
the following conditions to assist the
regeneration process:
•

Drive your vehicle in more favorable
conditions, which you will find at higher
vehicle speeds in normal driving, on a
main road or freeway for a minimum
of 20 minutes. This drive may include
short stops that will not affect the
regeneration process.

•

Avoid prolonged idling and observe
speed limits and road conditions.

•

Do not switch the ignition off.

•

Select a suitable gear to ideally
maintain engine speed between 1500
and 3000 RPM.

DIESEL PARTICULATE FILTER
MANUAL REGENERATION

WHAT IS DIESEL PARTICULATE
FILTER MANUAL REGENERATION

Diesel particulate filter manual
regeneration allows you to manually start
regeneration of the diesel particulate filter
at idle to clean the filter.

Note:

If you are not sure whether your

vehicle has this feature, contact your
authorized dealer.

DIESEL PARTICULATE FILTER
MANUAL REGENERATION
PRECAUTIONS

WARNING:

Stay clear of the

exhaust tailpipe during regeneration. Hot
exhaust gases can burn you badly.

You may not be able to use manual
regeneration if the service engine soon
warning lamp appears in the information
display.

Note:

During the use of manual

regeneration, you may observe a light
amount of white smoke. This is normal.

DIESEL PARTICULATE FILTER
MANUAL REGENERATION
REQUIREMENTS

You can use the manual regeneration
feature when a message appears in the
information display and you are not able
to drive in a manner that allows effective
automatic active regeneration or if you
choose to manually start the regeneration
of the diesel particulate filter while the
vehicle is idle.

218

Diesel Particulate Filter - Diesel

Before you start manual regeneration, do
the following:
•

Make sure the parking brake is on.

•

Shift into park (P) on stable, level
ground.

•

Park your vehicle outside of any
structure.

•

Park your vehicle 10–15 ft (3–5 m)
away from any obstructions and away
from materials that can easily combust
or melt, for example paper, leaves,
petroleum products, fuels, plastics and
other dry organic material.

•

Make sure there is a minimum of 1/8
tank of fuel.

•

Make sure all fluids are at proper levels.

DIESEL PARTICULATE FILTER
MANUAL REGENERATION
LIMITATIONS

You cannot use manual regeneration until
the diesel particulate filter load percentage
has reached 100% or Full. The diesel
particulate filter load percentage
fluctuates up and down when driving your
vehicle due to active and passive
regenerations.

If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than 25 mph (40 km/h), short
drive cycles, drive time less than 15 minutes
or the vehicle does not fully warm up,
passive and active regeneration may not
sufficiently clean the diesel particulate
filter system.

Aftermarket devices or modifications to
the exhaust system may reduce the
effectiveness of the exhaust system as
well as cause damage to the exhaust
system or engine. This may also degrade
vehicle performance and could lead to
engine damage that may not be covered
by the vehicle Warranty.

STARTING DIESEL PARTICULATE
FILTER MANUAL REGENERATION

Start with your vehicle engine and when it
has reached the normal operating
temperature, press the information display
control button on the steering wheel. See

Instrument Cluster Display

(page 140).

If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning
appears in the information display. See

Diesel Particulate Filter – Information
Messages

(page 220). Answer yes to this

prompt and then follow the next prompts
regarding exhaust position required to
initiate manual regeneration. Be sure to
understand each prompt. If you are not
sure what is being asked by each prompt,
contact an authorized dealer. The display
confirms the operation has started and
when it has finished. You can also drive to
clean the filter.

E67028

When the system is at the point
of oversaturation, the
malfunction indicator lamp

illuminates and a message appears in the
information display. You cannot initiate
filter cleaning. You must have your vehicle
checked as soon as possible.

Once manual regeneration starts, engine
speed increases and the cooling fan speed
increases. You will hear a change in audible
sound due to engine speed and cooling fan
speed increases.

It is not necessary to open the hood on the
engine compartment. Once manual
regeneration completes, the engine speed
returns to normal idling. The exhaust
system remains very hot for several
minutes even after regeneration is
complete. Do not reposition the vehicle
over materials that could burn until the

219

Diesel Particulate Filter - Diesel

exhaust system has had sufficient time to
cool. Depending on the amount of soot
collected by the diesel particulate filter,
ambient temperature and altitude, manual
regeneration lasts approximately 30
minutes.

WHAT IS THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM

The selective catalytic reduction system
helps reduce tailpipe emissions and
requires Diesel Exhaust Fluid (DEF) to
convert nitrogen oxides into nitrogen and
water.

HOW DOES THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM WORK

The selective catalytic reduction system
injects diesel exhaust fluid into the exhaust
system to enable correct selective catalytic
reduction system function.

The usage of diesel exhaust fluid has
increased from prior model years in order
to meet more stringent emissions
requirements. The diesel exhaust fluid
usage ranges from approximately 2-6%
of fuel burned (100.00 gal (378.54 L) of
fuel requires approximately 2.00 gal
(7.57 L)to 6.00 gal (22.71 L) of diesel
exhaust fluid) depending on vehicle usage.
Factors that influence diesel exhaust fluid
usage may include:

•

Payload/Towing

•

Driving Style

•

Altitude

•

Humidity

•

Temperature

SELECTIVE CATALYTIC
REDUCTION SYSTEM
PRECAUTIONS

WARNING:

Keep diesel exhaust

fluid out of reach of children. Avoid
contact with skin, eyes or clothing. In
case of contact with your eyes, flush
immediately with water and get prompt
medical attention. In case of contact
with your skin, clean immediately with
soap and water. If you swallow any
diesel exhaust fluid, drink plenty of
water, call a physician immediately.

WARNING:

Only refill the diesel

exhaust fluid tank in a well ventilated
area. When you remove the diesel
exhaust fluid tank filler cap or a diesel
exhaust fluid container cap, ammonia
vapors may escape. Ammonia vapors
can be irritating to skin, eyes and mucous
membranes. Inhaling ammonia vapors
can cause burning to the eyes, throat and
nose and cause coughing and watery
eyes.

WARNING:

Diesel exhaust fluid

must be refilled when low or replaced
when contaminated or your vehicle
speed becomes limited to 50 mph
(80 km/h). In these conditions, drive with
caution and refill diesel exhaust fluid
immediately. If the diesel exhaust fluid
becomes empty or contaminated and
fluid is not replaced, your vehicle
becomes limited to engine idle only once
stopped. In these conditions, be cautious
where you stop your vehicle because you
may not be able to drive long distances
or maintain highway speeds until you
refill or replace the diesel exhaust fluid.

222

Selective Catalytic Reduction System - Diesel

WARNING:

Tampering with or

disabling the selective catalytic
reduction system results in severe
vehicle performance limitation including
eventual speed limiting to 5 mph
(8 km/h).

Note:

Do not put diesel exhaust fluid in the

fuel tank. Do not start the engine if any
amount of diesel exhaust fluid was added
to the diesel fuel tank as it will likely lead to
failure of the fuel pump and injectors and
may result in severe engine damage which
your vehicle Warranty may not cover. The
diesel fuel tank must be completely drained
and cleaned prior to being refilled with clean
diesel fuel and starting the engine.

Selective catalytic reduction systems are
sensitive to contamination of the diesel
exhaust fluid. Maintaining the purity of the
fluid is important to avoid system
malfunctions. If you remove or drain the
diesel exhaust fluid tank, do not use the
same fluid to refill the tank. The system
has a sensor to monitor fluid quality.

Driving without refilling, replacing
contaminated diesel exhaust fluid, or
having the selective catalytic reduction
system repaired results in the following
actions as required by the California Air
Resources Board (CARB) and the U.S.
Environmental Protection Agency (EPA):
•

Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.

•

Further vehicle operation without
refilling or replacing contaminated
diesel exhaust fluid causes the engine
to enter an idle-only condition. This
only occurs upon vehicle refueling,
vehicle idling in park for 1 hour, or
engine shutdown for 10 minutes or
more and is indicated by a message in
the information display indicating
required actions to resume normal
operation. It is required to add a
minimum of 1.0 gal (3.8 L) of diesel
exhaust fluid to the tank to exit the
idle-only condition, but your vehicle is
still in the speed-limiting mode until
you refill the tank completely.

Note:

For vehicle speed limiting or idle-only

condition, normal vehicle operation resumes
when you refill the diesel exhaust fluid tank
or repair the contaminated system. If the
system is contaminated or inoperative, have
your vehicle checked as soon as possible.

REQUIREMENTS

E163354

Only use diesel exhaust fluid that is
certified by the American Petroleum
Institute (API).

You can purchase diesel exhaust fluid at
an authorized dealer, or contact roadside
assistance for help in finding a retailer that
sells diesel exhaust fluid.

Note:

Non-certified diesel exhaust fluid use

can cause damage that your Warranty may
not cover

SELECTIVE CATALYTIC
REDUCTION SYSTEM
GUIDELINES

•

Diesel exhaust fluid is non-flammable,
non-toxic, colorless and water-soluble
liquid.

•

In order for the system to operate
correctly you must maintain the diesel
exhaust fluid level.

•

Do not overfill the diesel exhaust fluid
tank.

•

Diesel exhaust fluid is corrosive.

•

Avoid spilling diesel exhaust fluid on
painted surfaces, carpeting or plastic
components. Immediately wipe away
any diesel exhaust fluid that has spilled
with a damp cloth and water. If it has
already crystallized, use warm water
and a sponge.

•

Do not store the diesel exhaust fluid
bottle in your vehicle. If it leaks it could
cause damage to interior components
or release an ammonia odor inside your
vehicle.

•

Do not re-use the diesel exhaust fluid
container once it is emptied.

•

Store diesel exhaust fluid out of direct
sunlight and in temperatures between
23–68°F (-5–20°C).

•

The system has a diesel exhaust fluid
quality sensor. Dilution of diesel
exhaust fluid or use of any other liquid
in the selective catalytic reduction
system leads to a diesel exhaust fluid
system fault, eventually leading to the
vehicle only operating in idle-only
mode.

•

Do not dilute diesel exhaust fluid with
water or any other liquid.

FILLING THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM TANK

FILLING THE SELECTIVE
CATALYTIC REDUCTION SYSTEM
TANK IN COLD WEATHER

Diesel exhaust fluid may freeze if the
ambient temperature is below 12°F (-11°C).
Your vehicle has a preheating system
which allows diesel exhaust fluid to
operate below 12°F (-11°C). If you do not
use your vehicle for an extended period
when the ambient temperature is below
12°F (-11°C), the fluid in the tank may
freeze.

224

Selective Catalytic Reduction System - Diesel

If the DEF tank is frozen, it may not
recognize when the tank is refilled. The DEF
level will update once the tank thaws out.
It is best to fill the DEF tank prior to, or after
a drive cycle greater than 20 minutes to
allow the remaining frozen DEF in the tank
to liquefy. If the tank is overfilled and the
fluid freezes it may cause damage that
your Warranty will not cover.

Note:

After filling the DEF tank, there may

be a short period before the increased level

WHAT IS THE CATALYTIC
CONVERTER

The catalytic converter is part of your
vehicle's emissions system and filters
harmful pollutants from the exhaust gas.

CATALYTIC CONVERTER
PRECAUTIONS

WARNING:

Do not park, idle or

drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire.

WARNING:

The normal operating

temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off.

WARNING:

Exhaust leaks may

result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.

To avoid damaging the catalytic converter:
•

Do not crank the engine for more than
10 seconds at a time.

•

Do not run the engine with a spark plug
lead disconnected.

•

Do not push-start or tow-start your
vehicle. Use booster cables. See

Jump

(page 420).

•

Use the correct fuel. See

Fuel and

Refueling

(page 209).

•

Do not switch the ignition off when your
vehicle is moving.

•

Avoid running out of fuel.

•

Have the items listed in scheduled
maintenance information performed
according to the specified schedule.

Note:

Do not make any unauthorized

changes to your vehicle or engine. By law,
vehicle owners and anyone who

POWER TAKE-OFF

(IF EQUIPPED)

HOW DOES THE POWER TAKE-
OFF WORK

Auxiliary equipment called power take-off,
or PTO, is often added to the engine or
transmission to operate utility equipment.
Examples include a wheel-lift for tow
trucks, cranes, tools for construction or tire
service, and pumping fluids. PTO
applications draw auxiliary horsepower
from the powertrain, often while the
vehicle is stationary. In this condition, there
is limited cooling air flow through the
radiator and around the vehicle that
normally occurs when a vehicle is moving.
The aftermarket PTO system installer,
having the most knowledge of the final
application, is responsible for determining
whether additional chassis heat protection
or powertrain cooling is required, and
alerting the user to the safe and proper
operation.

Note:

Use of auxiliary equipment that

exceeds the maximum Power Take-Off
(PTO) load specified in our Truck Body
Builders Layout Book can adversely affect
the performance of the powertrain system.
Refer to the Body Builders Layout Book for
instructions about the appropriate
installation of additional equipment.

WHAT IS THE SPLIT SHAFT
CAPABILITY

The split shaft capability feature allows
you to install an aftermarket split shaft
gearbox in your vehicle's driveline and run

gearbox and allows the engine to power
the power takeoff, when the engine is
running and the split shaft software is
enabled.

2-speed Electronic Shift On the Fly (ESOF)
transfer case which is also known as a
part-time system. This system offers the
driver two-wheel drive high, four-wheel
drive high, and four-wheel drive low as
available modes of operation. When you
select either four-wheel drive high or
four-wheel drive low, the system provides
mechanically locked four-wheel drive
power to both the front and rear wheels
for use in off-road or slippery conditions
such as deep snow, sand or mud. When
you select four-wheel drive low, the system
provides additional gearing for increased
torque multiplication for conditions like
deep sand, steep slopes, or pulling heavy
objects. Additionally, the system is capable
of recreational flat towing by putting the
transfer case into a neutral position. See

Recreationally Towing Your Vehicle

(page 426).

There is further information available on
driving in unique driving conditions. See

Off-Road Driving

(page 409).

LOCK

E339076

Your vehicle has manual hub locks on
either the driver side or the driver and
passenger side of your vehicle. For proper
operation, make sure that each hub is fully
engaged and that both hub locks are set
to the same position (both set to lock or
both set to auto). To engage lock, turn the
hub locks completely clockwise. To engage
auto, turn the hub locks completely
counterclockwise.

The ESOF four-wheel drive system:

•

Provides 4x4 High engagement and
disengagement while the vehicle is
moving.

•

Operates by a push button control
located on the instrument panel that
allows you select 4x2, 4x4 High or 4x4
Low operation.

•

Uses auto-manual hub locks. When set
to auto, the hubs engage and
disengage automatically based on the
4x4 mode you select. When set to lock,
the hubs remain engaged at all times.

•

Increases fuel economy when used in
the hub lock's recommended auto
mode.

Note:

Auto-manual hub locks manually

lock by rotating the hub lock control from
auto to lock.

Note:

Hub locks should be in auto mode

when in 4x2 mode. If hub locks are in lock
mode in 4x2 mode, there will be additional
noise from the front axle.

FOUR-WHEEL DRIVE
PRECAUTIONS

WARNING:

Vehicles with a higher

center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.

WARNING:

Do not become

overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.

Truck and utility vehicles differ from
passenger cars. Your vehicle could be
higher to allow it to travel over rough
terrain without getting stuck or damaging
underbody components. The differences
that make your vehicle so versatile also
make it handle differently than passenger
cars. Always maintain steering wheel
control, especially in rough terrain. Since
sudden changes in terrain can result in
abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes. Drive
cautiously to avoid vehicle damage from
concealed objects such as rocks and
stumps. Drive slower in strong crosswinds
which can affect the normal steering
characteristics of your vehicle. Be
extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.

Note:

Your vehicle may come with a front

air dam that can become damaged (due to
reduced ground clearance) when taking your
vehicle off-road. To prevent damage,
remove the 15 bolts securing the air dam
and remove.

FOUR-WHEEL DRIVE
LIMITATIONS

Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surface roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components. Four-wheel
drive high or four-wheel drive low modes
are intended for consistently slippery or
loose surfaces. Use of four low mode on
these surfaces could produce some noise,
such as occasional clunks, but should not
damage drive components. When
transitioning from consistently loose or
slippery surfaces, be sure the four-wheel
drive system is not mechanically blocked
once on dry, hard surface roads in
two-wheel drive high.

Note:

In certain scenarios, where the

four-wheel drive system has difficulty
engaging, a

To Engage 4x4 Slow to 3 MPH

To Engage 4x4 Slow to 5 km/h

message could appear in the instrument
cluster.

Operating Four-Wheel Drive with
a Spare or Worn Tires

Your four-wheel drive system is not
intended to provide full function with tires
that have different levels of wear or with
a dissimilar spare tire. Incorrect use of
four-wheel drive with such tires can cause
system damage.

235

Four-Wheel Drive

(If Equipped)

If there is a difference in the level of wear
among tires on the vehicle or if you install
a dissimilar spare tire on the vehicle, do not
use 4WD High or 4WD Low (if equipped)
other than to get your vehicle unstuck.
After getting your vehicle unstuck, shift to
2H by performing the following steps:

Come to a stop on a flat, horizontal
surface

2. Shift the transmission to park (P) for

automatic transmissions and neutral
(N) for manual transmissions.

3. Switch to two-wheel drive mode.

4. Shift the transmission to reverse (R).

5. Shift the transmission to drive (D) for

automatic transmissions and to first
gear for manual transmissions. This
ensures the transfer case system is not
trapped in place.

Note:

When the system detects a spare or

worn tires and a four-wheel drive
engagement request above a designated
speed, a warning message appears in the
instrument cluster. See

Four-Wheel Drive

– Information Messages

(page 239).

Note:

In certain scenarios, where the

four-wheel drive system has difficulty
engaging, a

To Engage 4x4 Slow to 3 MPH

To Engage 4x4 Slow to 5 km/h

message could appear in the instrument
cluster.

Mechanical Shift Blocking

On four-wheel drive vehicles with a
mechanically locked four-wheel drive high
mode, the transfer case distributes torque
to the front wheels by mechanically
interlocking the front and rear driveshafts
together. Various external factors affect
shifting performance of this type of system
including, but not limited to:

•

Vehicle acceleration.

•

Dissimilar tire sizes.

•

Steering input.

If the system detects a mechanical shift
blockage at speed after you select
two-wheel drive high, the message "4x4
Unable to Disengage See Manual", could
display momentarily. If this message
displays, one or more of the following
actions can relieve the mechanical shift
block:

•

Momentary acceleration.

•

Momentary braking.

•

Bringing the vehicle to a stop.

•

Shifting the transmission to neutral and
back to drive.

•

Shifting the transmission to reverse
and back to drive.

•

Driving the vehicle around a tight turn
at a slow speed.

Note:

In certain scenarios, where the

four-wheel drive system has difficulty
engaging, a warning message appears in
the instrument cluster. See

Four-Wheel

Drive – Information Messages

(page 239).

SWITCHING FOUR-WHEEL
DRIVE ON AND OFF

A vehicle that comes with four-wheel drive,
when selected, has the ability to use all
four wheels to power itself. This increases
traction, which may enable you to safely
drive over terrain and road conditions that
a conventional two-wheel drive vehicle
cannot.

On some four-wheel drive models, the
initial shift from two-wheel drive to
four-wheel drive while the vehicle is
moving can cause a momentary clunk and
ratcheting sound. These sounds are normal
as the front drivetrain comes up to speed
and are not cause for concern.

236

WHAT IS THE ELECTRONIC
LOCKING DIFFERENTIAL

The electronic locking differential is a
device housed in the rear axle and when
activated, allows both wheels on that axle
to turn at the same speed. The electronic
locking differential provides additional
traction should your vehicle become stuck.

HOW DOES THE ELECTRONIC
LOCKING DIFFERENTIAL
WORK

You can activate the differential
electronically and shift it on the fly within
the operating speed range. The electronic
differential disengages when the vehicle
speed exceeds a set value and it reengages
when the vehicle speed drops below a set
value. See

Switching the Electronic

Locking Differential On and Off

(page

242). The electronic locking differential
could engage based on certain selected
drive modes. See

Selecting a Drive Mode

(page 309). The electronic locking
differential is for use in mud, rocks, sand,
or any off-road condition where you need
maximum traction.

Note:

The electronic locking differential is

for off-road use only and is not for use on
dry pavement. Using the electronic locking
differential on dry pavement results in
increased tire wear, noise and vibration.

Note:

The electronic locking differential

activates or deactivates automatically
based on speed, four-wheel drive mode, and
drive mode selection. See

Switching the

Electronic Locking Differential On and
Off

(page 242).

ELECTRONIC LOCKING
DIFFERENTIAL PRECAUTIONS

Operating the Electronic Locking
Differential with a Spare or
Mismatched Tires

On vehicles with an electronic locking
differential, the size of the spare tire can
affect performance of the system. If there
is a significant difference between the two
rear tires, you may have limited electronic
locking differential functionality. If the
system has difficulty disengaging, release
the accelerator pedal and turn the steering
wheel in the opposite direction when
rolling. We recommend engaging and
disengaging the electronic locking
differential at a stop when you mount a
spare on the rear axle.

may flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop.

ANTI-LOCK BRAKING SYSTEM

ANTI-LOCK BRAKING SYSTEM
LIMITATIONS

The anti-lock braking system does not
eliminate the risk of crash 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 travel further.
Maintain pressure on the brake pedal.

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. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.

BRAKES – FREQUENTLY ASKED
QUESTIONS

Is it normal for my brakes to make
noise?

Occasional brake noise is normal. If a
metal-to-metal, continuous grinding, or
squeal sound is present, the brake lining
could be worn. Have the system checked.

There is an electrical motor sound
when I press on the brake pedal or
activate the park brake switch. Is
this normal?

Yes, those sounds are the electronic brake
booster or the electronic park brake
operating.

Note:

Brake dust could accumulate on the

wheels, even under normal driving
conditions. Some dust is normal as the
brakes wear and does not contribute to
brake noise. See

Cleaning Wheels
