1987 Volvo 760
Alternator warning light
If the light comes on while the engine is running, check the tension of the alternator drive belt as soon as
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 in 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").
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 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.
Anti- lock Brake System ABS
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.
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
