Volvo 2006 S60 - Manual (Page 103)

If the engine is warm, wait for at least 10-15 minutes after the engine has been switched off before checking the oil.
Checking the oil
1. Pull out the dipstick and wipe it with a lint free rag.
2. Reinsert the dipstick, pull it out, and check the oil level.
3. Add oil if necessary. If the level is close to the MIN mark, add approximately 1 US quart (1 liter) of oil.
4. Run the engine until it reaches normal operating temperature.
5. Switch off the engine and wait for at least 10-15 minutes and recheck the oil level. If necessary, add oil until the
level is near the mark.
CAUTION:
- Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
- Never fill oil above the MAX mark. This could cause an increase in oil consumption.
- Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
- Always add oil of the same type and viscosity as already used.
WARNING!
Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces.
R-models
R-models are equipped with an oil level warning system. If the engine oil level becomes too low, the warning light in
the instrument panel will come on and a warning will be displayed in the text window.
If the yellow warning light in the instrument panel comes on and the text OIL LEVEL LOW/FILL OIL is displayed,
stop safely as soon as possible and add 1 qt (1 liter) of oil. Check the oil level with the dipstick before restarting the
engine.
If the red warning light in the instrument panel comes on and the text OIL LEVEL LOW/STOP SAFELY-->STOP
ENGINE-->SEE MANUAL is displayed, stop safely as soon as possible and add oil (not more than 1.6 qts (1.5 liters).
Check the oil level with the dipstick before restarting the engine. If no oil level is visible on the dipstick, do not start
the engine. Have the car towed to an authorized Volvo workshop.
