Malfunction Indicator Lamp (MIL)
The Ma lfunction Indicator Lamp (MI L) ¢,ij in the

nostic (OBD II) system .
T he wa rning/indicator light ill uminates when the

gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly.
If the li ght do es not go out after the eng ine is
sta rted, or i lluminates while you are driving, a
malfunction may exist in the engine system. If
the lig ht illuminates, the catalytic converter
could be damaged.

with reduced power (avoiding
s ustained high speeds and/o r rapid accelera­
tions) and have the condit ion corrected. Contact
your authori zed Aud i dea ler .
If the light i llum inates, the elect ronic speed lim­
iter may also be malf unct ion ing. For more infor­
