Do not drive in the overrevving range, as this
could damage the engine.

engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.

You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the temperature measured and

Opening the hood when the engine is over-
heated or when there is a fire in the engine

injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
