After the engine is switched off, the enginecompartment temperature is monitored for approx. 30 minutes.

During this period, and depending on temperature, the engine-compartment blower may continue to run or start to run.

  • Carry out work in these areas only with the engine off, the ignition off, and exercise extreme caution.

Engine Oil
It is important to perform oil changes regularly in accordance with the intervals specified in the "Maintenance" booklet.

Engine oil consumption
It is normal for your engine to consume oil.

The rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well as the amount of dilution and oxidation of the lubricant.

If the vehicle is used for repeated short trips, and consumes a normal amount of oil, the engine oil measurement may not show any drop in the oil level at all, even after 600 miles (1,000 km) or more. This is because the oil is gradually becoming diluted with fuel or moisture, making it appear that the oil level has not changed.

The diluting ingredients evaporate out when the vehicle is driven at high speeds, as on an expressway, making it then appear that oil is excessively consumed after driving at high speeds.

If the conditions you drive your vehicle in are dusty, humid, or hot, the frequency of the oil change intervals should be greater.
