exhaust system FORD F53 2017 Owners Manual

If the light is blinking, engine misfire is
occurring which could damage your
catalytic converter. Drive in a moderate
fashion (avoid heavy acceleration and
deceleration) and have your vehicle
serviced immediately.
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. Have your vehicle
serviced immediately. The service engine soon indicator light
illuminates when the ignition is first turned
on prior to engine start to check the bulb
and to indicate whether the vehicle is ready
for Inspection/Maintenance (I/M) testing.
Normally, the service engine soon light will
stay on until the engine is cranked, then
turn itself off if no malfunctions are
present. However, if after 15 seconds the
service engine soon light blinks eight times,
it means that the vehicle is not ready for
I/M testing. See Emission Control
System (page 30).
Transmission Tow/Haul
(If Equipped) Illuminates when the tow/haul
feature has been activated. If the
light flashes steadily, have the
system serviced immediately, damage to
the transmission could occur.
AUDIBLE WARNINGS AND
INDICATORS
Fail-Safe Cooling Warning Chime
Sounds when the coolant gauge pointer
has moved to hot. There are three stages
of chimes: •
Stage 1 is a single chime when the
engine temperature begins to overheat.
• Stage 2 is multiple chimes and engine
power becomes limited in order to help
cool the engine.
• Stage 3 is multiple chimes and the
engine will shut down.
Headlamps On Warning Chime
Sounds when you remove the key from the
ignition and open the driver's door and you
have left the headlamps or parking lamps
on.
Key in Ignition Warning Chime
Sounds when you open the driver's door
and you have left the key in the ignition.
Parking Brake On Warning Chime
Sounds when you have left the parking
brake on and drive your vehicle. If the
warning chime remains on after you have
released the parking brake, have the
system checked by your authorized dealer
immediately.
Shift to Park Warning Chime
Sounds when you open the driver's door
and your vehicle is not in park.

GENERAL INFORMATION
WARNINGS
Extended idling at high engine
speeds can produce very high
temperatures in the engine and
exhaust system, creating the risk of fire or
other damage. 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. Do not start the engine in a closed
garage or in other enclosed areas.
Exhaust fumes can be toxic. Always
open the garage door before you start the
engine. If you smell exhaust fumes inside
your vehicle, have your vehicle
checked by an authorized dealer
immediately. Do not drive your vehicle if
you smell exhaust fumes. If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately 5 miles
(8 kilometers) after you reconnect it. This
is because the engine management system
must realign itself with the engine. You can
disregard any unusual driving
characteristics during this period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start the engine, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the
engine. IGNITION SWITCH
A (accessory) - Allows the electrical
accessories, such as the radio, to operate
while the engine is not running.
Note: Do not leave the ignition key in this
position for too long. This could cause your
vehicle battery to lose charge.
B
(lock) - Locks the gearshift lever and
allows key removal.
C
(off) - The ignition is off.
Note: When you switch the ignition off and
leave your vehicle, do not leave your key in
the ignition. This could cause your vehicle
battery to lose charge.
D
(on) - All electrical circuits are
operational and the warning lamps and
indicators illuminate.
E
(start) - Cranks the engine.
STARTING A GASOLINE
ENGINE
When you start the engine, the idle speed
increases, this helps to warm up the
engine. If the engine idle speed does not
slow down automatically, have your
vehicle checked by an authorized dealer.

Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of your
vehicle
’s fuel economy under current
driving conditions. Keeping records during
summer and winter will show how
temperature impacts fuel economy.
Conditions
• Heavily loading your vehicle reduces
fuel economy.
• Carrying unnecessary weight in your
vehicle may reduce fuel economy.
• Adding certain accessories to your
vehicle such as bug deflectors, rollbars
or light bars, running boards and ski
racks may reduce fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures.
• Fuel economy may decrease when
driving short distances.
• You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.
EMISSION CONTROL SYSTEM WARNINGS
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. 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. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
•
Use only the specified fuel listed.
• Avoid running out of fuel.
• Do not turn off the ignition while your
vehicle is moving, especially at high
speeds.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
such non-Ford parts should be equivalent
to genuine Ford Motor Company parts in
performance and durability.
Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
