INSPECTIONM17JCAF +’
(1) Referring to the VACUUM HOSES ROUTING, confirm that
the vacuum hoses are properly connected.
(2) Check the hoses for irregularities (disconnection, loose-
ness, etc.) and confirm that there is no breakage or
damage.
INSTALLATIONM17JDAF(1) When connecting a hose, firmly press it onto the nipple.
(2) Referring to the VACUUM HOSES ROUTING, connect the
hoses correctly.

INSPECTIONMl7NCAA
Inspect for damage, cracking or deterioration. Replace if faulty.
Caution1. Operation of any type, including idling, should be
avoided if engine misfiring occurs. Under this conditionthe exhaust system will operate at abnormally high
temperature, which may cause damage to the catalystor underbody parts of the vehicle.
2.Alteration or deterioration of ignition or fuel system, or
any type of operating condition which results in enginemisfiring must be corrected to avoid overheating the
catalytic converters.
3.Proper maintenance and tune up according to manufac-turer’s specifications should be made to correct the
‘bi
conditions as soon as possible.TSB Revision

SHIFT PATTERNSTwo shift patterns are pre-stored in the control unit of this
transaxle. One is the power pattern (for more powerful
performance), and the other is the economy pattern (for
improved fuel consumption and quieter operation).
The driver can select and switch to the desired pattern by using
the power/economy select switch on the center
Iconsole.The solid lines shown in these shift patterns indicate up-shifts,
and the broken lines indicate down-shifts. The reason why
there is a difference between the shift points for upshifts and
for down-shifts is so that up-shifts and down-shifts will not
occur frequently when driving at a speed in the vicinity of the
shift point.
When the vehicle is stopped, there is a shift to 2nd gear in
order to obtain a suitable “creeping”, but when the accelerator
pedal is then depressed the vehicle starts off in 1st gear.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
(1)A Supplemental Restraint System (SRS), which uses a driver-side air bag, has been installed in the 3000GT.(2)The SRS includes the following components: impact sensors, SRS diagnosis unit: SRS warning light, air bagmodule, clock spring, interconnecting wiring. Other SRS-related components (that may have to be
removed/installed in connection with SRS service or maintenance) are indicated in the table of contents byan asterisk (*).
WARNING!(1)Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to
personal injury or death to service personnel (from inadvertent firing of the air bag) or to the driver (from
rendering the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an
authorized MITSUBISHI dealer.(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B
-Supplemental Restraint System (SRS), before beginning any service or maintenance of any component of the
SRS or any SRS-related component.
