Warning lights
The warning lights described on pages 18 and 19 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

On-Board Diagnostics II (OBDII): As you
drive, a computer called “OBDII” monitors
your car’s engine, transmission, electrical and
emission systems. The CHECK ENGINE
light will light up if the computer senses a
condition that potentially may need correcting.
When this happens, please have your car
checked by a Volvo retailer as soon as
possible.
A CHECK ENGINE light may have many
causes. Sometimes, you may not notice a
change in your car’s behavior. Even so, an
uncorrected condition could hurt fuel econo-
my, emission cleanliness, and driveability.
Extended driving without correcting the cause
could even damage other components in your
car.

Fuel requirements
Deposit control (detergent) gasoline
Volvo recommends the use of detergent gasoline to control engine
deposits. Detergent gasoline is effective in keeping injectors and intake
valves clean. Consistent use of deposit control gasolines will help ensu\
re
good driveability and fuel economy. If you are not sure whether the
gasoline contains deposit control additives, check with the service
station operator.

Emissions maintenance
Periodic maintenance helps minimize
emissions
Periodic maintenance will help keep your vehicle running well. Your
Warranty and Service Records Information booklet provides a
comprehensive periodic maintenance schedule up to 150,000 miles
(240,000 km) of vehicle service. The schedule includes components that
affect vehicle emissions. This page describes some of the emission-
related components.
Engine air filter
The engine air filter cleans particles from air entering the engine.
Replace the engine air filter cartridge with a new one every 37,500
miles (60,000 km) under normal driving conditions. Replace the
cartridge more often when the vehicle is driven under dirty and dusty
conditions. The cartridge cannot be cleaned, and should always be
replaced with a new one.
Fuel filter
The fuel filter should be replaced at 105,000 miles (168,000 km). The
filter is replaced as a complete unit. Replace more frequently if
contaminated fuel is introduced into the tank, or if there is reason to
suspect that this has occurred.
Fuel system, including filler cap, tank, lines,
and connections
The ability of the fuel system to contain hydrocarbons depends upon a
leak-free system. Inspect fuel lines every 30,000 miles (48,000 km).
Check for proper sealing of the fuel filler cap, which contains “O”\
ring
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 light (Malfunction Indicator) may indicate a fault. However, your vehicle’s performance
will not be affected. Use only Volvo original or approved fuel filler caps.
Timing belt
For proper functioning of the engine and emission control systems, the
timing belt and belt tensioner must be replaced every 105,000 miles
(168,000 km). Engine damage will occur if the belt fails.
PCV system
(on turbocharged models)
The nipple in the intake manifold and the filter at the end of the PCV
hose in the air cleaner should be inspected and cleaned at 105,000 miles\
(168,000 km), and again at 150,000 miles (240,000 km).
Spark plugs
The spark plugs should be replaced every 60,000 miles (96,000 km)
under normal driving conditions. City driving or fast highway driving
may necessitate replacement sooner.
Under normal driving conditions, spark plugs require no maintenance
between replacement intervals. When installing new plugs, be sure to
use the right type and to tighten them correctly. When changing the
plugs, clean the terminals and rubber seals. Also check that the
suppressor connectors are in good condition. Cracked or damaged
connectors should be replaced.
