Air pump system (B5254S)
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 continue\
s to work until the catalytic
converter has reached normal working temperature, although it can also s\
tart when the engine is idling.
If the air pump is running and the engine is switched off, the pump cont\
inues working in order to protect
the pump motor.
Note! A soft whining noise can be heard from the pump, and when it perfo\
rms a self-diagnosis, the high/
low beam and the instrument lighting will flash briefly. This is complet\
ely normal. pg. 8:15 Windshield washer nozzles, Washer fluid reservoir
Adjusting washer nozzles
The washer jets should spray the windshield as shown above. Use the edge\
of a small screwdriver to
adjust the nozzles if necessary.
