pg. 18 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 light not go off after the engine has started, the system indicated should be inspected.
However, the parking brake reminder light will not go off until the parking brake has been fully released.
Malfunction indicator lamp
On-Board Diagnostic 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 economy, emission cleanliness, and driveability. Extended driving
without correcting the cause could even damage other components in your car.
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. However, your vehicle's performance will not be affected. Use only Volvo
original or approved fuel filler caps.
Canadian models are equipped with this warning light:
Oil pressure warning light
If the light comes on while driving, stop the car and then stop the engine immediately and check the engine oil
level . See page 116.
If the light stays on after restart, have the car towed to the nearest authorized Volvo retailer. After
hard driving, the light may come on occasionally when the engine is idling. This is normal, provided it goes off when
the engine speed is increased.
Roll Over Protection System (ROPS)
If the warning lamp remains on after the engine has started or comes on while you are driving, the ROPS self -
diagnostic system has detected a fault. The car should be driven to an authorized Volvo retailer as soon as possible for
inspection.
Please refer to page 10
for more information on the ROPS system.
Brake failure warning light
If the light comes on while driving or braking, stop immediately, open the hood and check the brake fluid level

Fuel filler door control on driver's door
Refueling
The fuel tank holds approximately 18 US gal. (68 liters) with sufficient volume left over to accommodate possible
expansion of the fuel in hot weather. Be aware that the "usable" tank capacity will be somewhat less than the specified
maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "Reid vapor pressure"
characteristics, and terrain can affect the fuel pumps' ability to supply the engine with an adequate supply of fuel.
Therefore, it is advisable to refuel as soon as possible when the needle nears the red zone, or when the fuel warning
light comes on.
Fuel filler door
The fuel filler door (on the right rear fender) is locked and must be popped open using the control on the driver's door.
Open fuel filler cap slowly during hot weather conditions
CAUTION:
Do not refuel with the engine running. Turn the ignition off or to position I. If the ignition is on, an incorrect reading
could occur in the fuel gauge.
After refueling, close the fuel filler cap by turning it clockwise until it clicks into place *.
Allow for fuel expansion by not overfilling the tank. Overfilling could also cause damage to the emission control
systems.
Avoid spilling gasoline during refueling. Gasolines containing alcohol can cause damage to painted surfaces, which
may not be covered under the New Vehicle Limited Warranty.
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the
New Vehicle Limited Warranty.
* 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. However, your vehicle's performance will not be affected. Use only Volvo
original or approved fuel filler caps.
pg. 63 Driving economy
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
ProCarManuals.com

Clean the contact surfaces on the wheel and hub. Lift the wheel and place it on the hub. Make sure that you align the
wheel with the guide stud on the wheel hub prior to installation. Install the wheel bolts crosswise (see illustration) and
tighten by turning lightly clockwise. Lower the vehicle to the ground and alternately tighten the bolts to 100 ft. lbs.
(130 Nm). Install the wheel cap (where applicable).
CAUTION: Correct tightening torque on wheel bolts must be observed. The wheel bolts should never be greased or
lubricated. The extended, chromed wheel bolts must not be used with steel rims, as they make it impossible to fit the
hub caps.
Correct tightening order for wheel bolts
pg. 88 Spare tire
Temporary Spare (certain models)
The spare tire in your car is called a "Temporary Spare". It has the following designation: T125/90 R15.
Recommended tire pressure (see decal on fuel filler flap) should be maintained irrespective of which position on the
car the Temporary Spare tire is used on.
In the event of damage to this tire, a new one can be purchased from your Volvo retailer.
CAUTION: The car must not be driven with wheels of different dimensions or with a spare tire other than the one that
came with the car. The use of different size wheels can seriously damage your car's transmission.
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. In other words, it must be replaced as soon as possible by a standard tire. Roadholding, etc., may be
affected with the "Temporary Spare" in use. Do not, therefore, exceed 50 mph (80 km/h).

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. 113 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
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.
ProCarManuals.com

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. 114 Fuel/emissions systems
Fuel system
The fuel system is all-electronic and is microprocessor-controlled. 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 air-fuel 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 three-ways 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.
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
ProCarManuals.com

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.
During a transitional period, a small number of service stations may still have fuel nozzles that are not compatible
with the fuel filler neck on cars equipped with the evaporative emission control system mandated by the U.S.
Environmental Protection Agency and the California Air Resources Board. If you experience difficulties in refueling
your vehicle, please ask the gas station attendant for assistance.
CAUTION:
Fuel must not be siphoned from the fuel tank. This will damage the evaporative emission control system.
