pg. 2 This manual deals with the operation and care of your Volvo
Welcome to the world-wide family of Volvo owners. We trust that you will enjoy many years of safe
driving in your Volvo, an automobile designed with your safety and comfort in mind. To ensure your
satisfaction with this vehicle, we encourage you to familiarize yourself with the equipment descriptions,
operating instructions and maintenance requirements/recommendations in this manual. We also urge you

and your passengers to wear seat belts at all times in this (or any other) automobile. And, of course,
please do not operate a vehicle if you may be affected by alcohol, medication or any impairment that
could hinder your ability to drive.
Your Volvo is designed to meet all applicable safety and emission standards, as evidenced by the
certification labels attached to the door opening sheet metal and on the left wheel housing in the engine
compartment. For further information regarding these regulations, please contact your dealer.
pg. 3 Seatbelts: "Something We Believe In"
Despite our strongest recommendation, and your best intentions, not wearing a seatbelt is like believing
"it'll never happen to me!". Volvo urges you and all adult occupants of your car to wear seatbelts and
ensure that children are properly restrained, using an infant, car or booster seat determined by age,
weight and height.
Fact: In every state, some type of child-restraint legislation has been passed. Additionally, some states
are seriously considering, or have already made it mandatory for occupants of a car to use seatbelts.
So, urging you to 'buckle up' is not just our recommendation - its becoming the law! The few seconds it
takes to buckle up may one day allow you to say, "Its a good thing I was wearing my seatbelt."
pg. 4 Introduction

thus, you may find features described and/or pictured in this manual that do not appear on your car.
Should you require more detailed information with regard to adjustments or repairs please contact your
Volvo dealer.
Do not export your Volvo to another country before investigating that country's applicable safety
and exhaust emission requirements. In some cases it may be difficult or impossible to comply with
these requirements. Modifications to the emission control system(s) may render your Volvo not
certifiable for legal operation in the U.S., Canada, and other countries.
pg. 5 Keys
The key number codes are stamped on a separate tag supplied with the keys. This tag should be
separated from the key ring and kept in a safe place.
The double-sided tape on the back of the tag can be used to secure it safely.
In the event the original keys are lost, duplicates may be ordered from your Volvo dealer.
The central locking system is described in detail in section "Door and locks".

possible.
NOTE: This warning light is illuminated if the alternator is not charging. However, parking brake,
brake failure and bulb failure warning lights will be illuminated at the same time due to the design
of the system.
Brake failure warning light
If the light comes on while driving and the brake pedal can be depressed further than normal, it is an
indication that one of the brake circuits is not functioning.
Stop immediately, open hood and check brake fluid level (see section "Brake fluid, Power steering")
WARNING!
Fluid level below MIN mark": Do NOT drive. Tow car to shop for check/repair of brake
system.
Fluid level between MIN and MAX mark: Proceed immediately and with caution to a Volvo dealer for
an inspection of the brake system.
Oil pressure warning light
If the light comes on during driving, the oil pressure is too low. Stop the car and then stop the engine
immediately. Do not drive the vehicle. See section titled "Engine oil".
After hard driving, the light will come on occasionally when the engine is idling. This is normal,
provided it goes off when the engine speed is increased.
Bulb failure warning light
The light will come on if any of the following bulbs are defective:
one of the low beam headlights
one of the tail lights
one of the brake lights (when the brake pedal is depressed)
Check the fuse and bulb.
See sections titled "Replacing bulbs" and "Fuses".
Should the warning light come on after a defective outside bulb has been replaced, the corresponding
bulb on the other side-of the car should also be replaced.

Parking brake reminder light
This light will be on when the parking brake (hand brake) is applied. The parking brake lever is situated
between the front seats.
pg. 12 Warning lights
Anti-lock Brake System (ABS)
The Anti-lock Braking System (ABS) is designed to improve vehicle control (i.e. stopping and steering)
during severe braking conditions by limiting wheel lock-up. When the system "senses" impending wheel
lock-up, braking pressure is automatically modulated in order to help prevent lock-up, which could lead
to a skid. While the system is modulating braking pressure, the driver may detect a pulsation of the
brake pedal. The on/off switching of ABS modulator may also be audible. This is normal.
Please be aware that ABS does not increase the absolute braking potential of the vehicle. Thus, while
control will be enhanced, ABS will not shorten stopping distances on slippery surfaces.
NOTE:
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will
however function) and the vehicle should be driven to a Volvo dealer for inspection.
SRS Supplemental Restraint System
If the light comes on (or stays on after the vehicle has started), the SRS diagnostic system has detected a
Fault. Take The car to an authorized Volvo dealer for an inspection of the system. See the SRS section
for more information.
Service reminder light
This light will come on at 5000 mile (8000 km) intervals. It is a reminder to the driver that the 5000 mile
(8000 km) service interval has been exceeded. The light will stay on 2 minutes after start until reset by
the servicing dealer.

For complete operating instructions, maintenance guidelines, and specifications, please consult your
Audio Cassette/Tuner instruction Booklet. The Booklet also contains information on radio reception and
the radio antenna.
Radio antenna mast
Note: Always lower the antenna mast When entering an automatic car wash.
The antenna should be cleaned and lubricated every 5,000 miles (8,000 km).
Multipath distortion
FM signals are typically "line-of-sight" and very reflective. Their reflectivity to objects such as
buildings, mountains or even other passing vehicles causes the condition known as multipath distortion.
This distortion is the result of the reflected signal and the direct signal reaching your antenna at slightly
different times causing a cancellation of all signals. This condition will sound like hissing or static. Very
little can be done to eliminate this problem, however, lowering the treble on your radio could help mask
these disturbances thereby allowing you to achieve optimum pleasure from your audio system.
pg. 14 Lighting, Turn signals, Hazard warning flasher
Headlights and parking light
All lights off
Parking lights on
Headlights and parking lights are on if starting (ignition) switch is in position I or II.

The cruise control switches are located on the turn signal switch lever.
To engage and set desired speed:
1. Set switch (B) to ON.
2. Accelerate to desired cruise speed.
NOTE: The cruise control cannot be engaged at speeds below 22 mph (35 km/h).
3. Depress SET SPEED switch (A).
Operating brake pedal
This will automatically disengage the cruise control. Previously selected cruise speed is retained in the
memory and by momentarily setting the switch to RESUME position that speed will be re-engaged.
NOTE:
The vehicle will accelerate very quickly should there be a substantial speed differential when the switch
is reset to RESUME. It is therefore recommended that the vehicle be accelerated manually and the
switch reset to RESUME once the speed differential has been reduced.
Acceleration
Momentary acceleration, such as for passing, does not interrupt cruise control operation. The previously
selected speed will be maintained without having to set switch to RESUME.
To disengage the cruise control system:
Set switch (B) to position OFF, or depress brake pedal.
Switching off the starting (ignition) switch is will automatically disengage the cruise control system.
WARNING!
The cruise control should not be used in heavy traffic or when driving on wet or slippery roads.
If the gear shift is moved to Neutral while the cruise control is engaged, then depress the brake pedal
momentarily, or set the cruise control switch (B) to OFF. This will disengage the cruise control and
prevent overreving the engine.
NOTE: When driving on a grade, actual vehicle speed may vary slightly from the set cruise control
speed.
