cates that the MIL is wor king properly.
If the light doe s not go out after the eng ine is
started, or i lluminates while you are driving, a
malfunction may exist in t he engine system. If
the light ill uminates, the catalytic converter
could be damaged.
Continue driving

tions) and have the condit ion corrected. Contact

for manually sw itching the w ipers on based
on v is ib il ity conditions.
-The w indshie ld may not be treated with wa­

when the blades are frozen to the wind­ s h ield can damage the wiper blades.
-Prior to using a car was h, the windshield
wiper system must be switched off (lever in
