the car.<br />
The engine-compartment blower is mounted in the<br />
engine compartment.<br />
Warning!<br />
Risk of injury.<br />
After the engine is switched off, the enginecompartment<br />
temperature is monitored for<br />
approx. 30 minutes.<br />
During this period, and depending on temperature,<br />
the engine-compartment blower<br />

Engine Oil<br />
It is important to perform oil changes regularly in<br />
accordance with the intervals specified in the<br />
“Maintenance” booklet.<br />
Engine oil consumption<br />
It is normal for your engine to consume oil.<br />
The rate of oil consumption depends on the quality<br />
and viscosity of oil, the speed at which the engine<br />
is operated, the climate, road conditions as well<br />
as the amount of dilution and oxidation of the<br />
lubricant.<br />
If the vehicle is used for repeated short trips, and<br />
consumes a normal amount of oil, the engine oil<br />
measurement may not show any drop in the oil<br />
level at all, even after 600 miles (1,000 km) or<br />
more. This is because the oil is gradually becoming<br />
diluted with fuel or moisture, making it appear<br />
that the oil level has not changed.<br />
The diluting ingredients evaporate out when the<br />
vehicle is driven at high speeds, as on an expressway,<br />
making it then appear that oil is excessively<br />
consumed after driving at high speeds.<br />
If the conditions you drive your vehicle in are<br />
dusty, humid, or hot, the frequency of the oil<br />
change intervals should be greater.
