pg. 1:4 Warning lights
The warning lights described on this page should never stay on when driving
When the ignition key is turned on, and before the engine starts, all of the warning lights should be on to
test the function of the bulbs. Should a light not go off after the engine has started, the system indicated
should be inspected. However, the parking brake reminder light will not go off until the parking brake is
fully released.
Alternator warning light
If the light comes on while the engine is running, check the tension of the generator drive belt as soon as
possible.
NOTE: This warning lights is illuminated if the generator 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.
Check Engine warning light
If the lamp comes on (or stays on after the vehicle has started), the Engine Check diagnostic system has
detected a fault. Drive to an authorized Volvo dealer for inspection.
Oil pressure warning light
If the light comes on while driving, the oil pressure is too low. Stop the car and then stop the engine
immediately and check the engine oil level. See the section titled "Engine oil". If the light stays on after
restart, have the car towed to the nearest authorized Volvo dealer. After hard driving, the light may come
on occasionally when the engine is idling. This is normal, provided it goes off when the engine speed is
increased.
