The radiator and radiator fans are in the front of
the car.
The engine-compartment blower is mounted on
the engine compartment lid.
/?\. Warning!
Risk of injury.
After the engine is switched off, the engine-
compartment and coolant temperatures are
monitored for approx. 20 minutes.
During this period, and depending on tem-
perature, the engine-compartment blower
and radiator fans may continue to run or
start to run.

Engine Oil
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 condi-
tions as well as the amount of dilution and oxida-
tion of the lubricant.
If the vehicle is used for repeated short trips,
and consumes a normal amount of oil, the en-
gine oil measurement may not show any drop in
the oil level at all, even after 600 miles (1000
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 ex-
pressway, making it then appear that oil is ex-
cessively 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.
If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is
high, the oil should be checked more frequently,
as driving conditions will determine the rate of
oil consumption.
- The engine in your vehicle depends on oil to
lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
- Make it a habit to have the engine oil level
checked with every fuel filling.
- The oil pressure warning light is not an oil
level indicator.
The oil pressure warning light indicates
serious engine damage may be occuring
when lit, if engine rpm is above idle speed.
