Petrol and Petrol-Ethanol Fuel Systems Health and SafetyPrecautions
WARNINGS:
Fuel may not give adequate warning before
toxic or harmful effects arise.
Exposure to fuel can be harmful and can
cause severe health damage or death.
Extreme care must be exercised when
handling hot fluids. Always wash off spilled
fluids from affected areas of skin
immediately.
Highly flammable mixtures are always
present and may ignite when working on
fuel systems. Do not allow naked flames,
sparks or lighted substances to come near
fuel related components.
Fuel must not be used as a cleaning agent.
Keep fuel containers tightly closed, out of
direct sunlight and in a cool area. Keep
away from heat sources, ignition sources
and oxidizing agents.
SKIN CONTACT: Excessive or prolonged
skin contact with diesel fuel may cause
serious skin disorders including skin
cancer.
SKIN CONTACT: Fuel is mildly irritating to
the skin and may cause dermatitis due to
defatting effect. Remove contaminated
clothing. Wash affected areas of skin with
soap and water. Seek medical attention for
any persistent skin irritation or
abnormality. Wash contaminated clothing
before reuse.
EYE CONTACT: Fuel is mildly irritating to
the eyes. Flush with plenty of running
water, blinking as often as possible. Do not
force the eyelid open. Seek medical
attention for any persistent eye irritation
or abnormality.
SWALLOWED: Fuel is moderately toxic
and tends to foam on vomiting. If drawn
into the lungs, inflammation may develop.
Do not induce vomiting. If spontaneous
vomiting occurs place the victim in a
forward position to reduce the risk of fuel
being drawn into the lungs. Give nothing
by mouth. If breathing but unconscious,
place in the recovery position. If breathing has stopped, apply artificial respiration.
Seek immediate medical attention.
INHALED: Fuel is toxic to the respiratory
and other body systems. Exposure may
result in various symptoms including
drowsiness, unconsciousness or severe
health damage. Move a victim to fresh air.
Keep a victim warm and at rest. If
unconscious, place in the recovery
position. If not breathing, apply artificial
respiration. Give cardiac massage if
necessary. Seek immediate medical
attention.
CAUTIONS:
Fuel injection equipment is manufactured
to very precise tolerances and fine
clearances. It is essential that absolute
cleanliness is observed when working with
these components.
Make sure that the workshop area in which
the vehicle is being worked on is as clean
and as dust free as possible.

Body Repair Health and Safety and General Precautions
General
Appropriate repair methods and carrying out repair
and paint jobs correctly is particularly important to
the operating safety of vehicles and the safety of
people.
WARNING: There is danger of injury
through:
• High voltage when electrical welding. – Do not perform welding work in a dampenvironment or on a wet substrate. Use
suitable insulation underneath.
• Welding spatter and UV radiation. – Wear protective clothing, gloves and weldingmask or welding goggles.
• Fire, explosion and hot surfaces in the work area.
– Always have a suitable fire extinguisheravailable when using welding or heating
equipment.
– Remove flammable substances from the danger area. Remove the fuel tank and fuel
pipes and hoses.
– Welding and grinding near the battery presents the danger of explosion. Remove
the battery before you start working.
– During paint work there is an increased danger of fire or explosion. Prevent any
sparks being created. Fire, open light and
smoking are forbidden.
– Always ventilate the workplace well and use an extraction system.
– Wear protective footwear made from anti-static material.
– Only use tools made of wood, brass or copper to clean stands and extraction ducts.
Do not use tools made of steel.
– Only fill or decant paint materials in a specially marked area. • Inhalation and/or absorption through the skin of
harmful substances.
– Welding fumes grinding dusts and solventvapours can be extremely harmful to the
health.
– Sealants, underbody protection and paint residues must not be burnt down with an
unshielded flame, as this will produce harmful
substances.
– Always ventilate the workplace well and use an extraction system.
– Wear protective clothing.
• Pyrotechnic components. – Disconnect the battery negative clamp andcover the battery terminal.
– Remove any airbag components.
• Noise – Cutting, grinding and alignment work cancause a noise level over 85 dB (A).
– Always wear ear protection.
• High Forces. – The various body areas are subject to veryhigh forces during realignment work. Should
any component suddenly become detached
during this process, there is a very great
danger of injury.
– Pulling chains and pulling shackles must be secured with arrester cables.
As well as these general instructions on the
dangers in body and paint shops, you must
observe:
• All valid local national and international regulations governing Health and Safety at Work
• Safety instructions of material equipment and tool manufacturers
For additional information, refer to: (100-00 General
Information) Solvents, Sealants and Adhesives (Description
and Operation),

Description
Item
Activated charcoal filter
1
Coarse filter
2
Filter masks with wadding, sponge or colloid filters
and also paper masks are all unsuitable for working
with coating materials because they do not stop
solvent vapors.
Eye protection
Cutting grinding welding solvents and paint bear
fundamental risks for your eyes.
Damage ranging from irritation of the cornea to
incurable illnesses is possible.
Solvents and paint – even water based – could not
only be absorbed via your skin but also via your
eyes.
Therefore always wear the appropriate eye
protection for your work.
Protective goggles must be inert toward splashes
of solvent, and must have side protection. Best
protection during spray painting is offered by full
mask respirators or helmet respirators with built-in
visor.
Skin protection
Spray painters must wear suitable protective work
clothing (flame-proof and anti-static). Also, when
working with water based materials, comprehensive
skin protection must be worn, because these
materials are very easily absorbed through the
skin.
Change your protective clothing at proper intervals.
Clothes contaminated with coating materials can
easily catch fire.
Do not choose clothes or underwear with a large
content of easy melting synthetic fiber, because
this material considerably increases the danger
and degree of injuries (melted plastic on the skin!). For areas of the skin which are not covered by
protective clothing suitable skin protection cleaning
and care agents must be used.
Ear protection
Cutting grinding compressors and extractor fans
and ducts are the main sources of noise in body
and paint shops.
Always wear suitable ear protection like ear plugs
or ear defenders.
Protection of the vehicle
Protect affected areas from weld spatter and dust
during all welding and grinding work on the vehicle.
If metallic dust stays on the vehicle for some time,
there is the likelihood of film rust formation.
Grinding produces tiny spots of damage to the paint
surface, which may cause corrosion. Also use
suitable protective measures to protect the interior
when performing repair operations which relate to
the inside of the vehicle.
For this reason, make sure to:
• Use carbon fiber blankets to protect the vehicle
body and the interior.
• Use covering film to protect the vehicle body from grinding dust and metal dust.
• Use covering paper to protect the interior from grinding dust.
In addition, take into account:
• Remove fuel supply components as necessary.
• Protect working areas which are in danger of catching fire with a fireproof blanket.
• Keep heat away from all components of the air conditioning system.
• Remove all components in the space adjoining the repair area.
Electronic components
Increased use of comfort and safety electronics in
modern vehicles requires additional attention to be
paid during body work.
Over voltages produced during welding can cause
electronic systems to be damaged. In particular,
the safety instructions for performing welding work
on vehicles with airbag systems must be adhered
to.
WARNING: After disconnecting the power
supply and before performing further work,
a wait time of up to 15 minutes must be

Auxiliary Climate Control – Overview
Initial start-up of the fuel-fired booster
heater
The fuel-fired booster heater needs to be filled
before being taken into operation for the first time.
Activation of the fuel pump for the fuel-fired booster
heater is controlled by the Ford diagnostic unit.
Lockout
Flame sensor
If the flame goes out independently during
operation of the booster heater, a restart is carried
out. If the booster heater does not ignite within 90
seconds of fuel delivery or if the flame goes out
within 15 minutes of starting, a lockout will be
implemented by the flame sensor.
Lockout can be cancelled by switching the booster
heater off then on again, although this may only
be repeated at most 2 times.
Overheating sensor
In the event of overheating (water shortage, poorly
ventilated coolant circuit), the fuel supply to the
booster heater is interrupted and a lockout occurs.
After the cause of the overheating has been
eliminated, the booster heater can be started again
by switching it off and on, if the coolant temperature
is below 70°C. If the booster heater overheats ten
times in a row, the control unit will be locked.
Unlocking the control unit
Delete the fault memory of the fuel-fired booster
heater after eliminating the cause of the fault using
the Ford diagnostic unit.

System Operation
Electric Booster Heater
In diesel vehicles which give off little residual heat,
a booster heater is used to heat the passenger
compartment rapidly in the case of low ambient
temperatures.
If the interior temperature has been set to HI, or if
the heater controls have been switched to the
highest setting, the two-zone air conditioning
system sends an "electric booster heater ON"
request signal to the CAN (controller area network)
via the medium speed GEM bus. If a manual air
conditioning system is installed, the signal is
transmitted via a conventional cable connection.
The GEM switches on the electric booster heater
depending on the following parameters:
• Engine coolant temperature is below 60 °C.
• Ambient air temperature is below 10 °C.
• Sufficient generator capacity is available.
The electric booster heater electronics activate
three output stages as a function of a pulse width
modulated signal PWM (pulse width modulation)
generated by the GEM. The output stages switch
the three heating elements of the electric booster
heater ON or OFF individually, whereby the heating
periods of the individual elements can overlap. Due
to the variable switch-on duration, continuously
variable temperature control is possible. The overall
heating power of the three heating elements is
linearly proportional to the PWM signal. If the PWM
signal is below 10% or above 95%, the electric
booster heater is not activated.
The electric booster heater is switched off when
an engine coolant temperature of 70°C or an
ambient air temperature of 20°C is exceeded.

Boost heat mode
When the engine is running, the booster heater
helps the engine to heat the passenger
compartment at low ambient temperatures.
When the coolant temperature reaches 30 °C, the
control unit transmits a switch-on signal for the
passenger compartment blower via the CAN bus.
When the coolant temperature drops, the blower
remains on until the temperature reaches 20 °C
whereupon it is deactivated.
The fuel tank must be filled to at least 14% for the
system to be switched on. If the fuel level drops
below 8% then the system is switched off.
In boost mode, the fuel fired booster heater is only
switched on if all of the following criteria are met:
• Engine speed above 500 rpm. The fuel fired booster heater is not allowed to start up while
the engine is being cranked; this prevents a
shut-down due to low voltage if the battery
charge is low.
• Ambient temperature below 5 °C.
• Fuel level above 14% of total capacity.
• Function is active on the trip computer menu.
One of the following conditions is sufficient to
switch off the booster heater in boost heat mode:
• Engine speed below 500 rpm.
• Ambient temperature above 11 °C.
• Function is active on the trip computer menu.
• Fuel level below 8% of total capacity.
Programmable fuel fired booster heater
The programmable fuel fired booster heater has
two operating modes:
• Instant start
• Programmed start
The heater status is displayed on the instrument
cluster display. The parking heater mode is controlled via a menu in the message centre. The
fuel fired booster heater can be activated and
deactivated via the message centre. (If set to 'Auto'
the system is activated, if set to 'Off' the system is
completely deactivated)
Immediate start-up of the booster
heater
This function enables the fuel-fired booster heater
to be switched on manually when the engine is not
running. This function is activated via the menu on
the driver information system.
The ignition key must be in the II" position before
this menu can be accessed. The timer function of
the booster heater remains active when the ignition
key is in position "0".
After an immediate start-up of the booster heater
it is switched off again after 30 minutes (or if the
fuel level in the fuel tank drops below 8%). The
booster heater stops within 2 minutes of the engine
starting. This leaves enough time to check whether
the switch-on conditions for boost heat mode have
been met, thus preventing the booster heater from
having to switch off and switch back on again. The
heater can be switched off manually at any time
from the menu.
Programmed start-up of the booster
heater
The driver can use a menu to adjust the time at
which the vehicle is to be pre-heated. The following
options are available:
• Time setting. One or two times can be
programmed for each day of the week. It is
possible to program days either individually or
together in groups (Mon-Sun/Mon-Sat/Mon-Fri).
• Time and data setting
With the first option, the fuel-fired booster heater
will start repeatedly without needing to be G1066982en

reprogrammed. However, if the engine hasn't been
run since the last programmed start, the fuel-fired
booster heater will not start up the second time so
as to prevent the battery from being discharged.
The length of time required to pre-heat the vehicle
is calculated in the control unit of the fuel-fired
booster heater and is based on two temperature
values:
• Ambient air temperature: this message is taken
from the GEM via the CAN bus.
• Coolant temperature: this is determined via an internal sensor in the fuel-fired booster heater.
The maximum heating time is 30 minutes at an
outside air temperature of -10 °C or lower. The
heating time decreases proportionally with
increasing ambient temperature until the ambient
temperature is between +15 °C and +20 °C. Then
the minimum heating time is 10 minutes. The
parking heater is deactivated at temperatures
above +20 °C.
The sequence for a programmed start of the
booster heater is as follows:
• Two minutes before the start of the maximum heating time the driver information
system/instrument cluster sends an activation
message to the fuel-fired booster heater via the
CAN bus.
• The fuel-fired booster heater calculates the required heating time and, if necessary, sends
a delay request on the CAN bus.
• At the calculated time, the fuel-fired booster heater starts up. The conditions for start-up are:
engine not running and amount of fuel in the
fuel tank is above 14% of maximum.
• When the coolant temperature reaches +30 °C, the control unit of the fuel-fired booster heater
sends a request to switch on the passenger
compartment blower.
• Eight minutes after the programmed switch-off time, the booster heater stops heating mode
and starts a run-on operation to clean the
system's spark plugs.
• Ten minutes after the switch-off time, the post-cleaning operation is complete. The
additional ten minutes run-on time provides
some leeway in case the driver is late arriving.
After a programmed start-up of the booster heater
it is switched off again after the heating time has
elapsed (or if the fuel level in the fuel tank drops
below 8%). The booster heater stops within 2 minutes of the engine starting. This leaves enough
time to check whether the switch-on conditions for
boost heat mode have been met, thus preventing
the booster heater from having to switch off and
switch back on again. The heater can be switched
off manually at any time from the menu.
Whilst the fuel-fired booster heater is in additional
heating mode and/or parking heating mode, the
instrument cluster receives a fuel consumption
signal; this is used to re-calculate the vehicle's
remaining range and fuel consumption data.
Emergency shutoff
In the event of an accident in which the airbags
are deployed, the control unit of the fuel-fired
booster heater receives a message on the CAN
bus from the restraints control module (RCM).
When this message is received, the booster heater
system switches off immediately.
The booster heater control module deactivates the
system and does not respond to further messages
on the CAN bus. The booster heater control module
needs to be activated with WDS.
Component Description
Electric Booster Heater
The electric booster heater consists of three
individual heating elements, which are incorporated
into a single housing. It is controlled by the generic
electronic module (GEM), taking into account the
following factors:
