2011 FORD F550 brake light

Using your vehicle as an ambulance
If your light truck is equipped with the Ford Ambulance Preparation
Package, it may be utilized as an ambulance. Ford urges ambulance
manufacturers to follow the recommendations of the Ford Incomplete
Vehicle Manual, Ford Truck Body Builder’s Layout Book and the
Qualified Vehicle Modifiers (QVM) Guidelines as well as pertinent
supplements. For additional information, please contact the Truck Body
Builders Advisory Service at http://www.fleet.ford.com/truckbbas/ and
then by selecting “Contact Us” or by phone at 1–877–840–4338.
Use of your Ford light truck as an ambulance, without the Ford Ambulance
Preparation Package voids the Ford New Vehicle Limited Warranty and
may void the Emissions Warranties. In addition, ambulance usage without
the preparation package could cause high underbody temperatures,
overpressurized fuel and a risk of spraying fuel which could lead to fires.
If your vehicle is equipped with the Ford Ambulance Preparation
Package, it will be indicated on the Safety Compliance Certification
Label. The label is located on the driver’s side door pillar or on the rear
edge of the driver’s door. You can determine whether the ambulance
manufacturer followed Ford’s recommendations by directly contacting
that manufacturer. Ford Ambulance Preparation Package is only available
on certain Diesel engine equipped vehicles.
Using your vehicle as a stationary power source (PTO)
Refer to the Driving chapter for more information and guidelines for
operating a vehicle equipped with an aftermarket power take-off system.
DATA RECORDING
Service Data Recording
Service data recorders in your vehicle are capable of collecting and
storing diagnostic information about your vehicle. This potentially
includes information about the performance or status of various systems
and modules in the vehicle, such as engine, throttle, steering or brake
systems. In order to properly diagnose and service your vehicle, Ford
Motor Company, Ford of Canada, and service and repair facilities may
access or share among them vehicle diagnostic information received
through a direct connection to your vehicle when diagnosing or servicing
your vehicle. For U.S. only (if equipped), if you choose to use the SYNC 
Vehicle Health Report, you consent that certain diagnostic information
may also be accessed electronically by Ford Motor Company and Ford
authorized service facilities, and that the diagnostic information may be
used for any purpose. See your SYNC  supplement for more information.Introduction

WARNING: Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.
Check fuel cap: Displays when the
fuel cap may not be properly
installed. Continued driving with
this light on may cause the Service
engine soon warning indicator to
come on. Refer to Fuel filler cap in
the Maintenance and Specifications chapter.
Low fuel (RTT): Displays when
the fuel level in the fuel tank is at
or near empty (refer to Fuel gauge
in this chapter).
Powertrain malfunction/Reduced
power/Electronic throttle
control (RTT): Displays when the
engine has defaulted to a
“limp-home” operation or when a transmission problem has been
detected and shifting may be restricted. If the light remains on, have the
system serviced immediately by your authorized dealer.
Brake system warning light: To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
when the engine is not running, or in a position between on and start, or
by applying the parking brake when the ignition is turned to the on
position.
If the brake system warning light does not illuminate at this time, seek
service immediately from your authorized dealer. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your authorized dealer. P!

WARNING: Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Anti-lock brake system: If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.
Airbag readiness: If this light fails
to illuminate when the ignition is
turned to on, continues to flash or
remains on, have the system
serviced immediately by your
authorized dealer. A chime will sound if there is a malfunction in the
indicator light.
Safety belt: Reminds you to fasten
your safety belt. A Belt-Minder 
chime will also sound to remind you
to fasten your safety belt. Refer to
the Seating and Safety Restraints
chapter to activate/deactivate the Belt-Minder  chime feature.
Charging system: Illuminates when
the battery is not charging properly.
If it stays on while the engine is
running, there may be a malfunction
with the charging system. Contact your authorized dealer as soon as
possible. This indicates a problem with the electrical system or a related
component.
Engine oil pressure (RTT and
static warning light): Displays
when the oil pressure falls below the
normal range. Refer to Engine oil
in the Maintenance and Specifications chapter.ABSInstrument Cluster

CLEANING EXHAUST FILTER (diesel engine only) — Displayed
when the vehicle has entered the cleaning mode. Various engine actions
will raise the exhaust temperature in the Diesel Particulate Filter (DPF)
system to burn off the particles (exhaust soot). After the particles are
burned off, the exhaust temperature will fall back to normal levels. This
message is NORMAL. Refer to your diesel supplement for more
information.
WARNING: When the CLEANING EXHAUST FILTER message
appears in the message center, do not park near flammable
materials, vapors or structures until filter cleaning is complete.
DRIVE TO CLEAN EXHAUST SYSTEM (diesel engine only) —
Displayed when the Diesel Particulate Filter (DPF) is full of particles
(exhaust soot) and the vehicle is not being operated in a manner to
allow normal cleaning. This message will stay on until the exhaust filter
cleaning has begun, at which time the CLEANING EXHAUST FILTER
message will be displayed. It is recommended the vehicle operator drive
the vehicle above 30 mph (48 km/h) until the CLEANING EXHAUST
FILTER message turns off. This message is NORMAL. Refer to your
diesel supplement for more information.
Note: If this message is ignored, your vehicle will continue to fill the
Diesel Particulate Filter (DPF) with particles (exhaust soot). If cleaning
is not permitted, the light will illuminate and engine power may be
limited. If the vehicle is still not operated in a manner to allow cleaning,
the service engine soon light will illuminate and engine power will
be further limited. Dealer service will then be required to restore your
vehicle to full-power operation. Instrument Cluster
