1) Replace at 105,000 miles (168,000 km)
2) Brake fluid should be changed at owner request every second year or 30,000 miles (48,000 km). The fluid
should be replaced once a year or every 15,000 miles (24,000 km) when driving under extremely hard
conditions (mountain driving, etc.).
3) Rotate tires at owner request.
The following items should be checked weekly by the driver (it takes only a few minutes):
Engine oil level, brake fluid level, radiator coolant level, operation of all lights, horns, windshield wipers, tire
pressure (all five tires), windshield washer fluid level
The following should also be carried out at regular intervals:
Washing (check all drain holes), polishing, cleaning
pg. 108 Servicing
Air cleaner
Replace the air cleaner cartridge with a new one every 30,000 miles (48,000 km). The cartridge should be replaced
more often when driving under dirty and dusty conditions. The filter cannot be cleaned and therefore should always be
replaced with a new one.
Timing belt
For proper functioning of the vehicle and its emission control systems, the timing belt and tensioner must be replaced
every 105,000 miles (168,000 km). Engine damage will occur if the belt fails.
Fuel system cap, tank and lines and connections
The effectiveness of the fuel system to contain hydrocarbons is dependent largely on a leakfree system. Check for
proper sealing of the fuel filler cap which contains "O" ring type seals.
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 ("Check Engine") may indicate a fault. However, your vehicle's performance will not be affected. Use only
Volvo original or approved fuel filler caps.
Fuel (line) filter
For proper functioning of the vehicle and its emission control systems, the fuel line filter should be replaced at 105,000
miles (168,000 km). The filter is replaced as one complete unit. Replace more frequently if contaminated fuel is
introduced into the tank (or if there is reason to suspect that this has occurred).

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.
