Starting check
After a few seconds, all lights except 10 and 22 will go out. Once the engine starts, 10 and 22 will also go out.
* Indicates failure of a brake light, not failure of the braking system (see item 16).
**MIL = Check Engine Lamp
pg. 20 Warning lights
The warning lights described on pages 20 and 21 should never stay on when driving
When the ignition key is turned on and before the engine starts, all of the warning lights should go on to test the
function of the bulbs. Should a light not go off after the engine has started, the system indicated should be
inspected. However, the parking brake reminder light will not go off until the parking brake has been fully
released.
Supplemental Restraint System (SRS)
If the light comes on (or stays on after the vehicle has started), the SRS diagnostic system has detected a fault.
Drive to an authorized Volvo retailer for an inspection of the system. See the SRS section for more information.
Check Engine Lamp
If the lamp comes on (or stays on after the vehicle has started), the engine diagnostic system has detected a
possible fault in the emission control system. Although driveability may not be affected, see an authorized Volvo
retailer as soon as possible for inspection.
NOTE : If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check
Engine Lamp may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo
original or approved fuel filler caps.
Oil pressure warning light
If the light comes on while driving, stop the car and then stop the engine immediately and check the engine oil
level . See page 112.
If the light stays on after restart, have the car towed to the nearest authorized Volvo
retailer. After hard driving, the light may come on occasionally when the engine is idling. This is normal,
provided it goes off when the engine speed is increased.
Parking brake reminder light
This light will be on when the parking brake (hand brake) is applied. The parking brake lever is situated
between the front seats.
WARNING!

WARNING!
The coolant fan may start or continue to operate (for up to 6 minutes) after the engine has been switched off.
pg. 110 Fuel/emissions systems
Fuel system
The fuel system is allelectronic and is microprocessorcontrolled. It can continually compensate for variation in engine
load, speed and temperature to give the best economy and power. A mass air flow sensor measures the inducted air. In
this way the system can make instantaneous adjustments for changes in air temperature or density, thus always
assuring the best economy with the lowest possible exhaust emissions.
Heated oxygen sensor
This is an emission control system designed to reduce emissions and improve fuel economy. The heated oxygen sensor
monitors the composition of the exhaust gases leaving the engine. The exhaust gas analysis is fed into an electronic
module. This adjusts the airfuel ratio to provide optimum conditions for combustion and efficient reduction of the three
major pollutants (hydrocarbons, carbon monoxide and oxides of nitrogen (NOx) by a threeway catalytic converter.
Secondary Air Injection (certain models)
This system adds air to the hot exhaust gases as they are expelled from the engine. This causes a secondary
combustion of residual hydrocarbons and carbon monoxide, resulting in lower emissions levels in the exhaust gases.
Crankcase ventilation
The engine is provided with positive crankcase ventilation which prevents crankcase gases from being released into the
atmosphere. Instead, the crankcase gases are admitted to the intake manifold and cylinders.
Evaporative control system
The car is equipped with an evaporative control system which prevents gasoline vapor from being released into the
atmosphere.
The system consists of a fuel tank with filler pipe and cap, a rollover valve, a Fill Limit Vent Valve (FLVV), vapor
vent lines, a charcoal canister, a purge line, a purge control valve and engine connections.
In addition, there is a pressure sensor connected to the fuel tank and a filter -protected Canister Close Valve (CCV) on
the atmospheric side of the canister, for system diagnosis.
The gasoline vapor is channeled through the rollover valve and the FLVV via the vapor vent lines into the charcoal
canister, where it is
stored. When the engine is started, the gasoline vapor is drawn from the charcoal canister to the engine's air intake
system and into the combustion process.
NOTE:
· If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Malfunction Indicator
Lamp may indicate a fault.
