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 converters.
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.
- Altering emission system components or location or removing components.
- Repeated use of leaded fuel.
NOTE: Unleaded fuel is required for cars with three-way catalytic converters
pg. 113 Brake system
Brake circuit malfunction
The brake system is a hydraulic system consisting of two master cylinders and two separate brake
circuits. If a problem should occur in one of these circuits, it is still possible to stop the car with the other
brake circuit.
If the brake pedal must be depressed farther than normal and requires greater foot pressure, the stopping
distance will be longer. A warning light in the instrument panel will light up to warn the driver that a
fault has occurred.
If this light comes on while driving or braking, stop immediately and check the brake fluid level in the
reservoir.
NOTE: Press the brake pedal hard and maintain pressure on the pedal - do not pump the brakes.
WARNING!
If the fluid level is below the MIN mark in the reservoir: DO NOT DRIVE. Tow the car to a Volvo
retailer and have the brake system inspected.
NOTE: When the car is at a standstill and the engine is idling, e.g. at a traffic light and the brake pedal
is depressed, the pedal may go down slightly. This is normal and is caused by an built-in function in the
power brake system.
