General
Information

• Never run the engine unless the work area is well ventilated.
Carbon monoxide kills.

WARNINGS (cont’d)
• Batteries give off explosive hydrogen gas during charging. Keep
sparks, lighted matches and open flame away from the top of the
battery. If hydrogen gas escaping from the cap vents is ignited, it
ignites the gas trapped in the cells and causes the battery
to explode.
• Connect and disconnect battery cables, jumper cables or a battery
charger only with the ignition off. Do not disconnect the battery
while the engine is running.
• Do not quick-charge the battery (for boost starting) for longer than
one minute. Wait at least one minute before boosting the battery a
second time.
• Do not allow battery charging voltage to exceed 16.5 volts. If
the battery begins producing gas or boiling violently, reduce the
charging rate. Boosting a sulfated battery at a high charging rate
can cause an explosion.
• The A/C system is filled with chemical refrigerant, which is
hazardous. The A/C system should be serviced only by trained
technicians using approved refrigerant recovery/recycling
equipment, trained in related safety precautions, and familiar with
regulations governing the discharging and disposal of automotive
chemical refrigerants.
• Do not expose any part of the A/C system to high temperatures
such as open flame. Excessive heat increases system pressure
and may cause the system to burst.
• Some aerosol tire inflators are highly flammable. Be extremely
cautious when repairing a tire that may have been inflated using an
aerosol tire inflator. Keep sparks, open flame or other sources of
ignition away from the tire repair area. Inflate and deflate the tire at
least four times before breaking the bead from the rim. Completely
remove the tire from the rim before attempting
any repair.
• Some cars are equipped with a Supplemental Restraint System
(SRS) that automatically deploys airbags and pyrotechnic seat
belt tensioners in the event of a frontal or side impact. These
are explosive devices. Handled improperly or without adequate
safeguards, they can be accidentally activated and cause serious
injury.
• The ignition system produces high voltages that can be fatal.
Avoid contact with exposed terminals and use extreme care when
working on a car with the engine running or the ignition on.

General
Information

• Place jack stands only at locations specified by manufacturer.
The vehicle lifting jack supplied with the vehicle is intended for tire
changes only. Use a heavy duty floor jack to lift the vehicle before
installing jack stands.
• Battery acid (electrolyte) can cause severe burns. Flush contact
area with water, seek medical attention.
• Aerosol cleaners and solvents may contain hazardous or deadly
vapors and are highly flammable. Use only in a well ventilated
area. Do not use on hot surfaces (such as engines or brakes).
• Do not remove coolant reservoir or radiator cap with the engine
hot. Burns and engine damage may occur.

CAUTIONS
• If you lack the skills, tools and equipment, or a suitable workshop
for any procedure described in this manual, we suggest you leave
such repairs to an authorized dealer or other
qualified shop.
• Before starting a job, make certain that you have all the necessary
tools and parts on hand. Read all the instructions thoroughly
and do not attempt shortcuts. Use tools appropriate to the work
and use only replacement parts meeting original specifications.
Makeshift tools, parts and procedures will not make good repairs.
• Use pneumatic and electric tools only to loosen threaded parts and
fasteners. Never use these tools to tighten fasteners, especially on
light alloy parts. Always use a torque wrench to tighten fasteners to
the tightening torque specification listed.
• Be mindful of the environment and ecology. Before you drain the
crankcase, find out the proper way to dispose of the oil. Do not
pour oil onto the ground, down a drain, or into a stream, pond or
lake. Dispose of in accordance with Federal, State and
Local laws.
• The control module for the Anti-lock Brake System (ABS) cannot
withstand temperatures from a paint-drying booth or a heat
lamp in excess of 95­°C (203­°F) and should not be subjected to
temperatures exceeding 85­°C (185­°F) for more than two hours.
• Before doing any electrical welding on cars equipped with ABS,
disconnect the battery negative (-) terminal (ground strap) and the
ABS control module connector.
• Always make sure the ignition is off before disconnecting battery.

CAUTIONS (cont’d)
• Label battery cables before disconnecting. On some models,
battery cables are not color coded.
• Disconnecting the battery may erase fault code(s) stored in control
module memory. Check for fault codes prior to disconnecting the
battery cables.
• If a normal or rapid charger is used to charge the battery,
disconnect the battery and remove it from the vehicle to avoid
damaging paint and upholstery.
• Do not quick-charge the battery (for boost starting) for longer than
one minute. Wait at least one minute before boosting the battery a
second time.
• Connect and disconnect a battery charger only with the battery
charger switched off.
• Sealed or “maintenance free” batteries should be slow-charged
only, at an amperage rate that is approximately 10% of the
battery’s ampere-hour (Ah) rating.
• Do not allow battery charging voltage to exceed 16.5 volts. If
the battery begins producing gas or boiling violently, reduce the
charging rate. Boosting a sulfated battery at a high charging rate
can cause an explosion.
