improper deployment of the system.
AIR CONDITIONING SERVICING
ANTI-LOCK BRAKE SYSTEM
On models equipped with anti-lock brake systems, ALWAYS observe the following cautions:
DO NOT attempt to bleed hydraulic system without first referring to the appropriate ANTI-LOCK
BRAKE SYSTEM article in the BRAKES Section.
DO NOT mix tire sizes. As long as tires remain close to the original diameter, increasing the width is
acceptable. Rolling diameter must be identical for all 4 tires. Some manufacturers recommend tires of the
same brand, style and type. Failure to follow this precaution may cause inaccurate wheel speed readings.
Use ONLY recommended brake fluids. DO NOT use silicone brake fluids in an ABS-equipped vehicle.
BATTERY WARNING WARNING:To avoid injury from accidental air bag deployment, read and carefully
follow all warnings and service precautions. See appropriate AIR BAG
RESTRAINT SYSTEM article in ACCESSORIES/SAFETY EQUIPMENT.
CAUTION: Disconnect negative battery cable before servicing any air bag system,
steering column or passenger side dash component. After any repair, turn
ignition key to the ON position from passenger's side of vehicle in case of
accidental air bag inflation
CAUTION: Avoid breathing R-134a refrigerant and PAG lubricant vapors, exposure
may irritate eyes, nose and throat. To remove R-134a from system use R-
134a recycling equipment that meets SAE J2210 specifications. If
accidental system discharge occurs, ventilate work area before resuming
service.
WARNING:R-134a service equipment or vehicle A/C systems SHOULD NOT be
pressure tested or leak tested with compressed air. Some mixtures of
air/R134a have shown to be combustible at elevated pressures. These
mixtures are dangerous and may cause fire and/or explosions. See AIR
CONDITIONING SERVICE article in GENERAL INFORMATION section.
CAUTION: The anti-lock brake system contains electronic equipment that can be
susceptible to interference caused by improperly installed or high output
radio transmitting equipment. Since this interference could cause the
possible loss of the anti-lock braking capability, such equipment should
be installed by qualified professionals.

FUEL SYSTEM SERVICE WARNING:When battery is disconnected, vehicles equipped with computers may
lose memory data. When battery power is restored, driveability problems
may exist on some vehicles. These vehicles may require a relearn
procedure. See COMPUTER RELEARN PROCEDURES article in GENERAL
INFORMATION section.
CAUTION: Before replacing a blown fuse, remove ignition key, turn off all lights and
accessories to avoid damaging the electrical system. Be sure to use fuse
with the correct indicated amperage rating. The use of an incorrect
amperage rating fuse may result in a dangerous electrical system
overload.
CAUTION: Indicator will cause a squealing or scraping noise, warning that brake
pads need replacement.
CAUTION: Continued operation of vehicle with a severe malfunction could cause
converter to overheat, resulting in possible damage to converter and
vehicle.
CAUTION: Any modification to the exhaust system on turbo models, which reduces
exhaust backpressure, will lead to lean fuel mixtures and excessive spark
advance. This could cause serious engine damage.
WARNING:Many solid state electrical components can be damaged by static
electricity (ESD). Some will display a warning label, but many will not.
Discharge personal static electricity by touching a metal ground point on
the vehicle prior to servicing any ESD sensitive component.
CAUTION: Never use non-detergent or straight mineral oil.
