Check the belt regularly to make sure it is in good condition and is clean. A worn or dirty belt can cause poor cooling and low generator output as well as impair the operation of the power steering and the air conditioning

unit.

NOTE : The belt on the S/V 70 is equipped with a self-tensioning mechanism and requires no adjustment between changes.

WARNING! The engine must not be running when this check is performed.

Air pump system (certain models)

When the engine is being started from cold, an electrical air pump which draws air to the exhaust system is activated. This starts an afterburning process which leads to reduced hydrocarbon and carbon monoxide (HC

and CO) emissions and reduces the warm-up period for the catalytic converter.

The pump starts when the car has been started and is moving. It continues to work until the catalytic converter has reached normal working temperature, although it can also start when the engine is idling. If the air pump

is running and the engine is switched off, the pump continues working in order to protect the pump motor.
