The M, L AM waves follow the earth's surface and reflect against the atmosphere. This gives them a wide range. Weak reception fading Because of the limited range of the U FM senders and the fact that these waves are very reflective, this problem usually occurs with U FM reception. Volvo Model distortion can result.

Because these waves are very reflective, static can result. This static 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 problem occurs largely in built-up areas. Volvo Model Cross modulation If you listen to a weak station in the vicinity of a stronger one, both stations may be received simultaneously. U- FM - reasons for distortion U FM is affected by the electrical systems of nearby vehicles, especially those without suppression.

The distortion increases if the station is weak or poorly set. The signal strength needs to be stronger for good stereo reception and this limits the effective range of the sender. We hope that this information proves to be useful and provides you with a better understanding of the problems related to car radio reception. Reception conditions are not always optimum and this is, of course, beyond our control. However, we have endeavored to make the Volvo Audio System of a quality that will enable you to enjoy the best possible reception no matter what the reception conditions may be.

The antenna should be cleaned at least every 5, miles 8, km or more frequently if needed. Use WD40 or 5. Spray it again. Wipe it clean and dry again. Cassettes Store cassettes in their cases.

Do not touch the tape surface with your fingers. Tapes should not be exposed to direct sunlight, or extreme temperatures. Keep tapes away from oil, grease and other contaminants. For optimal tape deck performance Volvo does not recommend the use of C tapes. Take up slack using a pen or pencil before inserting cassette in cassette slot. Cleaning cassette We recommend the use of Volvo Cleaning Cassette available as a genuine Volvo accessory.

Regular use improves sound quality, cleans vital parts and prevent tape tangle. Volvo Model Body and interior pg. This tag should be separated from the key ring and kept in a safe place.

Cover sharp edges on load to help prevent injury to occupants. Secure load to help prevent shifting during sudden stops by wrapping seat belt around armrest as shown. Please note that the flap in the rear seat is only intended for light loads such as skis, wood etc. Volvo Model Occupant safety pg. Volvo urges you and all adult occupants of your car to wear seat belts and ensure that children are properly restrained, using an infant, car or booster seat determined by age, weight and height.

Fact: In every state and province, some type of child-restraint legislation has been passed. Additionally, most states and provinces have already made it mandatory for occupants of a car to use seat belts.

So, urging you to "buckle up" is not just our recommendation - legislation in your state or province may mandate seat belt usage. The few seconds it takes to buckle up may one day allow you to say, "It's a good thing I was wearing my seat belt". Volvo Model Seat belts Always fasten the seat belts before you drive or ride. Two lights above the rear view mirror will be illuminated for seconds after the starting ignition key is turned to the driving position. One light is located in the instrument panel and one in the console between the front seats.

A chime will sound at the same time if the driver has not fastened his seat belt. The rear seats are provided with self-retracting inertia reel belts.

The front seats are provided with twin roller belts. To buckle: Pull the belt out far enough to insert the latch plate into the receptacle buckle for rear seats until a distinct snapping sound is heard. The seat belt retractor is normally "unlocked" and you can move freely, provided that the shoulder belt is not pulled out too far. The retractor will lock up as follows: q if the belt is pulled out rapidly q during braking and acceleration q if the vehicle is leaning excessively q when driving in turns In order for the seat belt to provide maximum protection in the event of an accident, it must be worn correctly.

When wearing remember: q The belt should not be twisted or turned. Make sure that the shoulder belt is rolled up into its retractor and that the shoulder and lap belts are taut.

Volvo Model Before exiting the car, check that the seat belt retracts fully after being unbuckled. If necessary, guide the belt back into the retractor slot. Any device used to induce slack into the shoulder belt portion of the three-point belt system will have a detrimental effect on the amount of protection available to you in the event of a collision. Volvo Model Center-rear belt adjustment wagon The center-rear seat belt is manually adjustable. It should always be adjusted to fit snugly across the lap.

To unfasten Depress red pushbutton in receptacle buckle and let the belts rewind into their retractors. Maintenance Check periodically that the anchor bolts are secure and that the belts are in good condition. Use water and a mild detergent for cleaning. Check seat belt mechanism function as follows: Attach the seat belt.

Pull rapidly on the strap. Check other traffic before performing the following check. Volvo Model In the above checks you should not be able to pull the belt out. During pregnancy Pregnant women should always wear seat belts. Remember that the belt should always be positioned in such a way as to avoid any possible pressure on the abdomen. The lap portion of the belt should be located low, as shown in the above illustration.

Never use a seat belt for more than one occupant. Never wear the shoulder portion of the belt under the arm, behind the back or otherwise out of position. Such use could cause injury in event of accident. As the seat belts lose much of their strength when exposed to violent stretching, they should be replaced after any collision, even though they may appear to be undamaged.

Never repair the belt on your own; have this done by an authorized Volvo dealer only. The Volvo SRS consists of a driver's side airbag with a driver's side knee bolster. The system is designed to supplement the protection provided by the three-point seat belt system.

The interior of an SRS-equipped Volvo looks very much the same as any other. The only indications of the system's presence are the "SRS" embossed on the steering wheel pad, and the knee bolster beneath the steering column. The airbag is folded and located in the center of the steering wheel. It is released only during certain frontal or front-angular collisions, depending upon the crash severity, angle, speed and object impacted.

The airbag is designed not to be released in the event of a side or rear-end collision, or during a rollover situation. For maximum protection, wear seat belts at all times. Be aware that no system can prevent all possible injuries that may occur in an accident. Volvo Model The airbag system includes a gas generator 1 surrounded by the airbag itself 2.

To deploy the system, the sensor 3 activates the gas generators causing the airbags to be inflated with nitrogen gas. As the movement of the seat's occupants compresses the airbags, some of the gas is expelled at a controlled rate to provide better cushioning.

The entire process, including inflation and deflation of the airbags, takes approximately two-tenths of a second. When installing any optional equipment make sure that the SRS system is not damaged. Do not attempt to service any component of the SRS yourself.

Attempting to do so may result in serious personal injury. If a problem arises, take your car to the nearest authorized Volvo Dealer for inspection as soon as possible.
