Three-Way Catalytic Converter - Volvo S40 2001 Owner's Manual

2001 Volvo S40 & V40
following should be observed:
· A battery connection to the wrong terminal will damage the electrical system. Before connections are
made, check the polarity of the battery with a voltmeter.
· If booster batteries are used for starting, they must be properly connected to minimize the risk of the
electrical system being damaged. For correct connection, see "Jump starting" section.
· Never disconnect the battery circuit (for example, to replace the battery) while the engine is running or
the ignition is switched on, as this will immediately ruin the generator. Always make sure that all the
battery connections are properly tightened.
· If any electrical welding work is performed on the vehicle, the battery's ground lead (negative cable)
and all the connecting cables of the generator must be disconnected and the welder cables placed as near
the welding points as possible.
· The radio must be turned off before the battery is disconnected.
· The anti-theft code must be re-entered before the radio will function properly.
· The electrical system in your car is designed to accommodate Volvo accessories.

Three-way catalytic converter

· Keep your engine properly tuned. Certain engine malfunctions, particularly involving the electrical,
fuel or distributor ignition systems, may cause unusually high three-way catalytic converter
temperatures. Do not continue to operate your vehicle if you detect engine misfire, noticeable loss of
power or other unusual operating conditions, such as engine overheating or backfiring. A properly
tuned engine will help avoid malfunctions that could damage the three-way catalytic converter.
· Do not park your car over combustible materials, such as grass or leaves, which can come into contact
with the hot exhaust system and cause such materials to ignite under certain wind and weather
conditions.
· Excessive starter cranking (in excess of one minute), with an intermittently firing or flooded engine,
can cause three-way catalytic converter or exhaust system overheating.
· Remember that tampering or unauthorized modifications to the engine or the vehicle may be illegal and
can cause three-way catalytic converter or exhaust system overheating. This includes:
- Altering fuel injection setting or components.
