pg. 12 Indicator lights
Service reminder light
This light will come on at 5000 mile (8000 km) intervals. It is a reminder to the driver to have the engine
oil and oil filter changed. The light will stay on 2 min. after start until reset by the servicing dealer.
Anti-lock Brake System ABS
ABS brakes are designed to prevent the brakes from locking under severe braking conditions. If the light
comes on while driving, there is a malfunction of the ABS system (the standard braking system will still
function), and the car should be driven to an authorized Volvo dealer for inspection.
The system "senses" when the brakes begin to lock. regulates the brake pressure and thereby helps
prevent the brakes from locking. When the system is activated, you may be aware of a slight vibration in
the brake pedal. The switching sound of the control unit in the engine compartment may also be audible.
This is quite normal.
Note that the ABS system does not increase the total braking capacity of your car. It does. however,
enable you to steer and helps to retain better control of the vehicle.
Shift indicator light (Manual transmission cars only)
The Volvo shift indicator light (S.I.L.) is a device designed to help you get even better gas mileage from
your Volvo car. Studies have shown that the best fuel economy is obtained by shifting gears at low
engine rpm and high relative engine load. The Volvo S.I.L. is calibrated to show you when to shift for
improved mileage without sacrificing smooth acceleration.
Use of the S.I.L. is simple. Shift to the next higher gear as soon as the light comes on. You may find
after using the S.I.L. for some time that your natural shifting rhythm will adapt to the S.I.L's suggestion.
Some drivers may even shift before the light comes on.
Obviously, there will be times when you need to shift later than the light would indicate, for example,
when climbing hills or trailer towing. Using the light regularly, however, should result in a mileage
