1999 VOLVO S80 ECU

Always fasten the seat belts before you drive or ride. A chime will sound several times if the driver has not
fastened his seat belt.
To buckle:
Pull the belt out far enough to insert the latch plate into the receptacle until a distinct click 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:
· if the belt is pulled out rapidly
· during braking and acceleration
· if the vehicle is leaning excessively
· when driving in turns
For the seat belt to provide maximum protection in the event of an accident, it must be worn correctly. When wearing
the seat belt remember:
· The belt should not be twisted or turned.
· The lap belt must be positioned low on the hips (not pressing against the abdomen).
Make sure that the shoulder belt is rolled up into its retractor and that the shoulder and lap
belts are taut.
Before exiting the car, check that the seat belt retracts fully after being unbuckled.
If necessary, guide the belt back into the retractor slot.
NOTE: Legislation in your state or province may mandate seat belt usage.
Adjusting shoulder belt
Lap portion of the belt should sit low
Child seats: Please refer to page 14
for information on securing child seats with the seat belts.
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.

pg. 56 Remote keyless entry system
Remote keyless entry system
Your car is equipped with a remote control transmitter. This transmitter uses a radio frequency which will allow
"keyless" entry into the passenger compartment or the trunk. You will be supplied with two coded key ring
transmitters, which will enable you to lock/unlock all doors and the trunk from a distance of 10-15 feet (3-5 meters).
On vehicles equipped with an alarm, the alarm will also be activated/deactivated by this system.
The car can also be locked/unlocked with the key.
As an extra security precaution in certain situations (valet parking, etc.), Volvo recommends that the transmitter not be
included when the keys are given to anyone. The service key can be used instead. If one of the transmitters is
misplaced, contact the nearest authorized Volvo retailer for assistance.

The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.WARNING!
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and does not include
cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by law. WARNING!
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and possible
tire failure.
