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) or at 120,000 miles (193,000 km) for
the 2.5T engine on AWD models. 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 and 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 vehicle and its emission control systems, the timing belt and belt tensioner
must be replaced every 105,000 miles (168,000 km) or at 120,000 miles (193,000 km) for the 2.5T
engine on AWD models. 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 thereafter, again at 150,000 mile (240,000 km)
intervals.
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.
