pg. 106 Long distance trips
Before a long distance trip
It is always worthwhile to have your car checked at a Volvo retailer bef\
ore driving long distances. Your
retailer will also be able to supply you with bulbs, fuses, spark plugs \
and wiper blades for your use in the
event that problems occur.
As a minimum, the following items should be checked before any long trip\
:
l Check that engine runs smoothly and that fuel consumption is normal.
l Check for fuel, oil, and fluid leakage.
l Check condition of accessory drive belts.
l Check transmission oil level*.
l Check state of the battery's charge.
l Examine tires carefully (the spare tire as well), and replace those th\
at are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be checked b\
y your Volvo retailer only.
l Check all lights, including high beams.
l Reflective warning triangles are legal requirement in some countries.
l Have a word with your Volvo retailer if you intend to drive in countries\
where it may be difficult to
obtain the correct fuel.
l Consider your destination. If you will be driving through an area where \
snow or ice are likely to
occur, consider snow tires.
* To prevent injury from contact with hot surfaces, do not inspect your \
car's transmission fluid yourself.
Have your car's transmission fluid level inspected by a qualified Volvo \
service technician.

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 le\
ak-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. Howev\
er, your vehicle's performance
will not be affected. Use only Volvo original or approved fuel filler ca\
ps.
Timing belt
For proper functioning of the engine and its emission control systems, t\
he 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 h\
ose in the air cleaner should be
inspected and cleaned at 105,000 miles (168,000 km) or at 120,000 mile\
s (193,000 km) for the 2.5T
engine on AWD models, and again at 150,000 miles (240,000 km).
Spark plugs
The spark plugs should be replaced every 60,000 miles (96,000 km) unde\
r normal driving conditions.
City driving or fast highway driving may necessitate replacement sooner.\
Under normal driving conditions, spark plugs require no maintenance betw\
een 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 sup\
pressor connectors are in good
condition. Cracked or damaged connectors should be replaced.
