Electrical System - Volvo XC90 User Manual

2005 VOLVO XC90
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 vehicle 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), or 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, the Electronic Control
Module, 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.
- Altering emission system components or location or removing components.
- Repeated use of leaded fuel.
NOTE: Unleaded fuel is required for vehicles with three-way catalytic converters.
