Health and Safety Precautions
Introduction
Many of the procedures associated with vehicle
maintenance and repair involve physical hazards
or other risks to health. This subsection lists,
alphabetically, some of these hazardous operations
and the materials and equipment associated with
them. Precautions necessary to avoid these
hazards are identified.
The list is not exhaustive and all operations and
procedures, and the handling of materials, should
be carried out with health and safety in mind.
Before using any product the Materials Safety Data
Sheet supplied by the manufacturer or supplier
should be consulted.
Acids and Alkalis
See alsoBattery Acids.
For example caustic soda, sulphuric acid.
Used in batteries and cleaning materials.
Irritant and corrosive to the skin, eyes, nose and
throat. Cause burns. Can destroy ordinary
protective clothing.
Avoid splashes to the skin, eyes and clothing. Wear
suitable protective impervious apron, gloves and
goggles. Do not breath mists.
Make sure access to eye wash bottles, shower and
soap are readily available for splashing accidents.
Display Eye Hazard sign.
Air Bags
See also Fire, Chemical Materials.
Highly flammable, explosive – observe No Smoking
policy.
Used as a safety restraint system mounted in the
steering wheel and passenger side of the
instrument panel.
The inflator contains a high-energetic propellant
which, when ignited, produces a VERY HOT GAS
(2500°C).
The gas generant used in air bags is Sodium Azide.
This material is hermetically sealed in the module
and is completely consumed during deployment.
No attempt should be made to open an air bag inflator as this will lead to the risk of exposure to
Sodium Azide. If a gas generator is ruptured, full
protective clothing should be worn when dealing
with the spillage.
After normal deployment, gloves and safety
goggles must be worn during the handling process.
Deployed air bags should be disposed of in a
plastic bag in accordance with local regulations at
an approved chemical waste site.
For additional information, refer to:
Supplemental
Restraint System (SRS) Health and Safety
Precautions (100-00 General Information,
Description and Operation).

See also Chlorofluorocarbon, Chemical Materials
Highly flammable, combustible – observe No
Smoking policy.
Skin contact may result in frostbite.
Instructions given by the manufacturer must be
followed. Avoid naked lights, wear suitable
protective gloves and goggles.
If refrigerant comes into contact with the skin or
eyes, immediately rinse the affected areas with
water. Eyes should also be rinsed with an
appropriate irrigation solution and should not be
rubbed. SEEK MEDICAL ASSISTANCE IF
NECESSARY.
For additional information, refer to: Air Conditioning
(A/C) System Health and Safety Precautions
(100-00 General Information, Description and
Operation).
Adhesives and Sealers
See also Fire, Chemical Materials.
Highly flammable, flammable, combustible –
observe No Smoking policy.
Generally should be stored in No Smoking areas.
Cleanliness and tidiness in use should be
observed, for example disposable paper covering
benches; should be dispensed from applicators
where possible; containers, including secondary
containers, should be labeled appropriately.

Water-based Adhesives/Sealers
Those based on polymer emulsions and rubber
latexes may contain small amounts of volatile toxic
and harmful chemicals. Skin and eye contact
should be avoided and adequate ventilation
provided during use.
Hot Melt Adhesives
In the solid state, they are safe. In the molten state
they may cause burns and health hazards may
arise from the inhalation of toxic fumes.
Use appropriate protective clothing and a
thermostatically controlled heater with a thermal
cut-out and adequate extraction.
Resin-based Adhesives/Sealers, for
example Epoxide and Formaldehyde
Resin-based
Mixing should be carried out in well ventilated
areas, as harmful or toxic volatile chemicals may
be released.
Skin contact with uncured resins and hardeners
can result in irritation, dermatitis, and absorption
of toxic or harmful chemicals through the skin.
Splashes can damage the eyes.
Provide adequate ventilation and avoid skin and
eye contact.
Anaerobic, Cyanoacrylate (super-glues)
and other Acrylic Adhesives
Many are irritant, sensitizing or harmful to the skin
and respiratory tract. Some are eye irritants.
Skin and eye contact should be avoided and the
manufacturers instructions followed.
Cyanoacrylate adhesives (super-glues) MUST NOT
contact the skin or eyes. If skin or eye tissue is
bonded, cover with a clean moist pad and SEEK
IMMEDIATE MEDICAL ATTENTION. Do not
attempt to pull tissue apart. Use in well ventilated
areas as vapors can cause irritation to the nose
and eyes.For two-pack systems see Resin-based and
Isocyanate Adhesives/Sealers.
Isocyanate (Polyurethane)
Adhesives/Sealers
See also
Resin-based Adhesives.
Individuals suffering from asthma or respiratory
allergies should not work with or near these
materials as sensitivity reactions can occur.
Over exposure is irritating to the eyes and
respiratory system. Excessive concentrations may
produce effects on the nervous system including
drowsiness. In extreme cases, loss of
consciousness may result. Long term exposure to
vapor concentrations may result in adverse health
effects.
Prolonged contact with the skin may have a
defatting effect which may lead to skin irritation
and in some cases, dermatitis.
Splashes entering the eye will cause discomfort
and possible damage.
Any spraying should preferably be carried out in
exhaust ventilated booths, removing vapors and
spray droplets from the breathing zone.

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

Noise Conditions
• Gear noise is typically a howling or whining dueto gear damage or incorrect bearing preload. It
can occur at various speeds and driving
conditions, or it can be continuous.
• Chuckle is a particular rattling noise that sounds like a stick against the spokes of a spinning
bicycle wheel. It occurs while decelerating from
64 km/h (40 mph) and can usually be heard all
the way to a stop. The frequency varies with
vehicle speed.
• Knock is very similar to chuckle, though it may be louder and occurs on acceleration or
deceleration. The teardown will disclose what
has to be corrected.
Clicking, popping or grinding noises may be caused
by the following:
• worn, damaged or incorrectly installed wheel bearing, suspension or brake component.
Check and rule out tires, exhaust and trim items
before disassembling the transmission to diagnose
and correct gear noise.
The noises described under Road Test usually
have specific causes that can be diagnosed by
observation as the unit is disassembled. The initial
clues are the type of noise heard on the road test
and driving conditions.
Vibration Conditions
Vibration at highway speeds may be caused by
the following:
• out-of-balance front or rear wheels.
• out-of-round tires.
Shudder or vibration during acceleration may be
caused by the following:
• damaged powertrain/drivetrain mounts.
• excessively high constant velocity (CV) joint operating angles caused by incorrect ride height.
Check ride height, verify correct spring rate and
check items under inoperative conditions.
Road Test
A gear-driven unit will produce a certain amount
of noise. Some noise is acceptable and may be
audible at certain speeds or under various driving
conditions, as on a newly paved asphalt road. The slight noise is in no way detrimental and must be
considered normal.
The road test and customer interview (if available)
provide information needed to identify the condition
and give direction to the correct starting point for
diagnosis.
1. Make notes throughout the diagnosis routine.
Make sure to write down even the smallest bit
of information, because it may turn out to be the
most important.
2. Do not touch anything until a road test and a thorough visual inspection of the vehicle have
been carried out. Leave the tire pressures and
vehicle load just where they were when the
condition was first observed. Adjusting tire
pressures, vehicle load or making other
adjustments may reduce the condition(s)
intensity to a point where it cannot be identified
clearly. It may also inject something new into
the system, preventing correct diagnosis.
3. Make a visual inspection as part of the preliminary diagnosis routine, writing down
anything that does not look right. Note tire
pressures, but do not adjust them yet. Note
leaking fluids, loose nuts and bolts, or bright
spots where components may be rubbing
against each other. Check the load space for
unusual loads.
4. Road test the vehicle and define the condition by reproducing it several times during the road
test.
5. Carry out the Road Test Quick Checks as soon as the condition is reproduced. This will identify
the correct diagnostic procedure. Carry out the
Road Test Quick Checks more than once to
verify they are providing a valid result.
Remember, the Road Test Quick Checks may
not tell where the concern is, but they will tell
where it is not.
Road Test Quick Checks
1. 24-80 km/h (15-50 mph): with light acceleration,a moaning noise is heard and possibly a
vibration felt in the front floor panel. It is usually
worse at a particular engine speed and at a
particular throttle setting during acceleration at
that speed. It may also produce a moaning
sound, depending on what component is
causing it. REFER to Tip-in Moan in the
Driveline Noise and Vibration Symptom Chart.
2. Acceleration/Deceleration: With slow acceleration and deceleration, a shake is

1 Check the brake pedal for free operation.
• Did the brake pedal operate freely?
zYe s INSTALL a new brake booster. TEST the
system for normal operation.
zNoINSTALL new brake pedal bushings. TEST
the system for normal operation.
Component Tests
Hydraulic Leak Check
NOTE: There is a common clutch and brake fluid
reservoir, therefore it is possible that a clutch leak
can lead to reduction in the reservoir level.
It is possible that all evidence of fluid leakage may
have washed off if the vehicle has been operated
in rain or snow, as brake fluid is water-soluble.
Refill the system, bleed then apply the brakes
several times. Examine the system to verify that
the reservoir fluid level is actually dropping. Locate
and repair the external leak. If the fluid level drops
and no external leak can be found, check for a
brake master cylinder bore end seal leak.
Brake System Check
Brake Pedal Reserve Check
Where a low brake pedal or the feel of a
bottomed-out condition exists, check for brake
pedal reserve.
1. Operate the engine at idle with the transaxle in the NEUTRAL position.
2. Apply the brake pedal lightly three or four times.
3. Allow 15 seconds for the vacuum to replenish the brake booster.
NOTE: This increased resistance may feel like
something has bottomed out.
4. Apply the brake pedal until it stops moving downward or an increased resistance to the
pedal travel occurs. 5. Hold the brake pedal in the applied position and
raise the engine speed to approximately 2000
rpm.
NOTE: The additional movement of the brake pedal
is the result of the increased engine manifold
vacuum which exerts more force on the brake
booster during engine rundown. This means that
additional stroke is available in the brake master
cylinder and the brake system is not bottoming out.
6. Release the accelerator pedal and observe that the brake pedal moves downward as the engine
returns to idle speed.
Brake Booster Functional Test
Inspect all hoses and connections. All unused
vacuum connectors should be capped. Hoses and
their connections should be correctly secured and
in good condition with no holes and no collapsed
areas. Inspect the check valve on the brake booster
for damage.
Brake Booster Operation Check
1. Check the hydraulic brake system for leaks orlow fluid.
2. With the transaxle in the NEUTRAL position, stop the engine and apply the parking brake.
Apply the brake pedal several times to exhaust
all the vacuum in the system.
3. With the engine turned off and the vacuum in the system exhausted, apply the brake pedal
and hold it down. Start the engine. If the vacuum
system is operating, the brake pedal will tend
to move downward under constant foot
pressure. If no motion is felt, the vacuum
booster system is not functioning.
