Refer to “Engine malfunction indicator
(“SERVICE ENGINE SOON” or “Check
engine light”)” on page 5-146 and follow the
appropriate measures.
A safety device in the Twin Clutch SST has
been activated due to a possible malfunction
in the Twin Clutch SST.
Refer to “If the gearshift lever position dis-
play is not showing” on page 5-73 and follow
the appropriate measures.
A safety device in the Twin Clutch SST has
been activated due to a possible malfunction
in the Twin Clutch SST or in the engine elec-
tronic control module.
Perform the following procedure.
1. Park your vehicle in a safe place and stop
the engine.
2. Restart the engine.
If the vehicle moves and accelerates normally
after this procedure is performed, there is no
malfunction in the transmission.
However, if the vehicle does not move or
accelerate normally, or if this problem occurs
repeatedly, have the vehicle checked by an
authorized Mitsubishi Motors dealer or a
repair facility of your choice as soon as possi-
ble.

The ACD is a system that improves accelera-
tion performance and straight-ahead stability
by regulating the differential limiting action
and power drive distribution of the center dif-
ferential.

Select the control mode from the following
three types to suit the driving conditions.
When the gearshift lever position display
is not showing
When warning display is showing or
when no warning is showing in the multi-
information display
CAUTION
 When the Twin Clutch SST fluid tempera-
ture is high, the engine idle speed when the
vehicle is stopped may increase or the vehi-
cle will have a weak tendency to creep.
After that, if the Twin Clutch SST fluid tem-
perature rises even higher, the warning
display will appear.

ential system)
(if so equipped)
CAUTION
 Do not over-rely on the ACD. Even the ACD
cannot prevent the natural laws of physics
from acting on the vehicle. This system, like
any other system, has limits and cannot help
you to maintain traction and control of the
vehicle in all circumstances. Reckless driv-
ing can lead to accidents. It is the driver’s
responsibility to drive carefully. This means
taking into account the traffic, road and envi-
ronmental conditions.
 Be sure to use tires that are the same speci-
fied size, type, and brand, and have no differ-
ence in the amount of wear for all four
wheels. Otherwise, the ACD may not work
properly.
NOTE
 If the parking brake lever is pulled up while
the vehicle is moving, the center differential
is designed to switch to a free state condition
which will allow the rear wheel to lock eas-
ier.
