If a two-post hoist is used to lift the car, the front lift arm pads should be positioned under the rear engine frame
mounts. The rear lift arm pads should be positioned under the rear supporting arm bracket.
CAUTION: Certain models have reduced ground clearance due to the design of the front spoiler. Please observe
caution when driving the car onto a garage hoist.
pg. 117 Emission 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 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
ProCarManuals.com

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). 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. 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.
pg. 118 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(s)
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.
Crankcase ventilation
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.

been successfully programmed. Release both buttons.
5. If you are programming a rolling code-equipped device (e.g., garage door opener or entry door lock), refer to
"Programming rolling codes" on the next page to complete the programming process.
Repeat steps 3 and 4 to program the other two transceiver buttons. If, after several attempts, you are unable to
successfully train the HomeLink® Universal Transceiver to learn your hand -held transmitter's signal, contact
HomeLink® toll-free 1-800-355-3515 (Internet: www.HomeLink.com
).
WARNING!
· If you use HomeLink® to open a garage door or gate, be sure no one is near the gate or door while it is in motion.
· Do not use the HomeLink® Universal Transceiver with any garage door opener that lacks safety "stop" and "reverse"
features as required by federal safety standards. (This includes any garage door opener model manufactured before
April 1, 1982) A garage door opener that cannot "detect" an object, signalling the door to "stop" and "reverse" does
not meet current federal safety standards. Using a garage door opener without these features increases the risk of
serious injury or death. For more information on this matter, call toll-free 1-800-355- 3515 (Internet:
www.HomeLink.com
).
pg. 195 HomeLink® Universal Transceiver (option)
NOTE - Canadian residents:
During programming, your hand -held transmitter may automatically stop transmitting. To successfully train
HomeLink® , continue to hold the HomeLink® button. At the same time, repeatedly press and hold your hand -held
transmitter's button at two-second intervals until HomeLink® has learned your transmitter's code. The HomeLink®
indicator light will flash first slowly, and then rapidly to indicate that the button has been successfully programmed.
Determining if your garage door uses a rolling code
Determining if your garage door uses a rolling code Determine, in one of the following ways, if your garage door uses
a rolling code system and is manufactured after 1996:
Refer to the garage door opener owner's manual for verification.
If your hand -held transmitter appears to program the HomeLink® Universal Transceiver but the programmed button
does not activate the garage door, your garage door opener may have a rolling code.
Press the programmed HomeLink® button. If the garage door opener has the rolling code feature, the HomeLink®
indicator light flashes rapidly and then glows steadily after approximately 2 seconds.
To train a rolling code garage door opener , follow these instructions after programming the desired transceiver
button according to "Programming the transceiver." The help of a second person may make training easier.
1. Locate the training button on the garage door opener motor head unit. The location and color of the training button
may vary. If you encounter difficulty, refer to the garage door opener owner's manual or call toll-free 1-800-355-3515
(Internet: www.HomeLink.com
).
2. Press the "training" button on the garage door opener motor head unit until the "training" light comes on.
3. Press and release the programmed HomeLink® button. Press and release the programmed HomeLink® button a
second time to complete the training process. Some garage door openers may require you to do this procedure a third
time to complete the training.
