INTRODUCTION REPAIR INSTRUCTION
AVENSIS REPAIR MANUAL (RM1018E)
NOTICE:

Confirm that the VSC warning light blinks.

VSC system will be reset when the engine is re-
started.

Fasten the vehicle with lock chains.
(b) NOTICES OF RELATED OPERATIONS TO VSC (1) Do not carry out unnecessary installation and re-
moval as it might disorder the adjustment of related
parts to VSC.
(2) Be sure to carry out the preparation for operation and the confirmation of operation completion in ac-
cordance with the instruction of the text and when
the related operations to VSC are performed.
10. FOR VEHICLES EQUIPPED WITH CATALYTIC CONVERTER
CAUTION:
If a large amount of unburned gasoline flows into the converter, it may cause overheating and is a
fire hazard. To prevent this, observe the following precautions.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling. Avoid idling the engine for more than 20 minutes.
(c) Avoid a spark jump test. (1) Perform a spark jump test only when absolutely necessary. Perform this test as rapidly as pos-sible.
(2) While testing, never race the engine.
(d) Avoid a prolonged engine compression measurement. Engine compression measurements must be performed as rapidly as possible\
.
(e) Do not run the engine when the fuel tank is nearly empty. This may cause the engine to misfire and create an extra load on the converter.
