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.
