LED alarm status indicator
Alarm
The radio signal emitted from the transmitter, which is used to set/unset the alarm, is a "rolling code" signal. This
means that the signal is changed randomly for each transmission and is intended to help prevent unauthorized
recording of the code.
When armed (set), the alarm continuously monitors a number of points on the car. The following conditions will set off
the alarm:
· The hood is opened
· The trunk is opened
· A door is opened
· The ignition switch is tampered with · The car is lifted or towed (if the car is equipped with the optional inclination
sensor)
· The battery is disconnected (if the car is equipped with the optional backup battery siren). The alarm will sound for
ten 30 second intervals, with a 5 second pause between intervals. This function cannot be interrupted
Arming (setting) the alarm
ProCarManuals.com

Press the LOCK button on the remote control, lock the car using the key in the driver's door or press the central lock
button on one of the doors with the door open. One long flash of the turn signals will confirm that the alarm is set.
Disarming the alarm
Press the UNLOCK button on the remote control or unlock the doors with the key.
Turning off (stopping) the alarm
If the alarm is sounding, it can be stopped by pressing the UNLOCK button on the remote control or by unlocking the
driver's door with the key.
If the alarm is stopped with the remote control, this will be confirmed by two short flashes from the turn signals.
"Panic" function
In an emergency situation, this feature can be used to attract attention.
Activate the "panic" function by pressing the red panic button on the remote control for at least 3 seconds or by
pressing this button twice within 3 seconds. The turn signals will flash, the interior lights will go on and the alarm will
sound.
The function can be turned off by pressing any of the buttons on the remote control or will stop automatically
after 25 seconds.
NOTE: This button will NOT unlock the car.
Audible alarm signal
An audible alarm signal is given either by a separate alarm horn or by the optional backup siren. One alarm cycle lasts
for 30 seconds.
Visual alarm signal
The visual alarm signal is given by flashing all turn signals and turning on the interior lighting for approximately 5
minutes.
pg. 49 Alarm
Automatic reset function
If only the driver's door is unlocked with the remote control, the lock will automatically reengage (re-lock) and the
alarm will reset after 2 minutes unless the door has been opened.
Temporarily disconnecting the alarm sensor(s)
In certain situations it may be desirable to disconnect the optional alarm sensors, particularly the inclination sensor, if,
for example, you drive your car onto a ferry where the rocking of the boat could trigger the alarm.
ProCarManuals.com

To temporarily disconnect the sensor(s) from the alarm system:
· With both doors closed, switch off the ignition and remove the key from the ignition switch
· Press the locking (left) side of the central locking button on the driver's door for at least 3 seconds
· The doors will first lock and then unlock after 3 seconds to confirm that the sensors have been disconnected
The car can then be locked in the usual way to set the alarm.
NOTE: The sensors will automatically be reconnected to the alarm system the next time the ignition is switched on.
LED alarm status signals
The status of the alarm system is indicated by the red LED at the top center of the dash:
· LED off - the alarm is not armed (set)
· LED flashes once per second - the alarm is armed (set)
· LED flashes rapidly before the ignition is switched on - the alarm has been triggered
· LED flashes rapidly for 15 seconds after the ignition has been switched on - a fault has been detected in the alarm
system. Contact a Volvo retailer.
Batteries
Each remote transmitter is powered by a three-volt battery, type CR 2016. If the range of the transmitter is noticeably
reduced, this indicates that the battery is weak and should be replaced.
Replacement: Remove the battery cover on the back of the transmitter with a coin. Replace the battery. Reinstall the
cover, making sure it is secured tightly to help protect the transmitter.
CAUTION: Do not attempt to service or repair any components of the alarm system yourself. This should only be
done by an authorized Volvo retailer.

Posted speed limits should not be exceeded.
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be
effective in keeping injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good
driveability and fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with
the service station operator.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations
require that pumps delivering unleaded gasoline be labelled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded gasoline only". Leaded
gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of leaded
gasoline will lessen the effectiveness of the emission control system and could result in loss of emission warranty
coverage. State and local vehicle inspection programs will make detection of misfueling easier, possibly resulting in
emission test failure for misfueled vehicles.
NOTE : Some U.S. and Canadian gasolines contain an octane enhancing additive called methly-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Malfunction Indicator Lamp located on your instrument panel may light. If this occurs, please return your
vehicle to an authorized Volvo retailer for service.
Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI of 91,
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON. (RON + MON/2).
The minimum octane requirement is AKI 87 (RON 91).

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.
ProCarManuals.com

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
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 control system (ORVR) 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 control system.

Engine
Liquid-cooled gasoline, 5-cylinder, in-line engine. Aluminum alloy cylinder block with castiron cylinder liners cast
directly into the block. Aluminum alloy cylinder head with double overhead camshafts and separate intake and outlet
channels.
Engine lubrication is provided by an eccentric pump driven from the crankshaft. Fullflow type oil filter. Exhaust
emission control is accomplished by multiport fuel injection, heated oxygen sensor(s) and threeway catalytic converter.
Charge air cooler (Intercooler)
Turbocharged engines employ a turbocompressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold by approx. 8.7
psi (over atmospheric pressure) and engine power output by approx. 50 horsepower over that developed by the
normallyaspirated engine. The charge air cooler (which resembles a radiator) is located between the turbocompressor
and inlet manifold.Designation: Volvo B 5234 T3
