AIR BAG MODULE AND SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURES

TSB Revision

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-439

DEPLOYED AIR BAG MODULE AND OPERATED
SEAT BELT PRE-TENSIONER DISPOSAL

After deployment and operation, the air bag module and seat
belt pre-tensioner should be disposed of in the same manner
as any other scrap parts, adhering to local laws and/or legisla-
tion. Observe the following precautions during air bag or seat
belt pre-tensioner disposal:
1. The inflator will be quite hot immediately following

deployment, so wait at least 30 minutes to allow it cool
before attempting to handle it.

2. Do not put water or oil on the air bag after deployment or on

the seat belt pre-tensioner after operation.

WARNING

If after following these precautions, any material does
get into the eyes or on the skin, immediately rinse the
affected area with a large amount of clean water. If
any irritation develops, seek medical attention.

3. There may be material on the deployed air bag module or

the operated seat belt pre-tensioner, that could irritate the
eye and/or skin. Wear gloves and safety glasses when
handling a deployed air bag module or the operated seat
belt pre-tensioner.

4. Tightly seal the air bag module and seat belt pre-tensioner in

a strong plastic bag for disposal.

5. Be sure to always wash your hands after completing this

operation.

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES

WARNING

•

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 and

passenger (from rendering the SRS inoperative).

•

Service or maintenance of any SRS component or SRS-related component must be performed only at an

authorized MITSUBISHI dealer.

•

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.

NOTE

The SRS includes the following components: SRS air bag control unit, SRS warning light, front impact sensors, driver’s and

passenger’s (front) air bag modules, knee air bag module, side-airbag module, curtain air bag module, side impact sensors,

seat belt pre-tensioners, clock spring, and 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 by an asterisk (*).

ACTIVE SKID CONTROL SYSTEM (ASC)

35C-2

GENERAL INFORMATION

M1355000200115

Active skid control (ASC) has been equipped as a
standard.

• ASC has been added to the transaxle <twin

clutch sportronic shift transmission (TC-SST)

*1

>

control and AWD <super all wheel control
(S-AWC)

*2

> control, and the controls are inte-

grated to improve the vehicle stability.

• The ASC system integrates the traction control

(TCL) function and skid control function.

• When the TCL function detects the slip of driving

wheel (for example, during startup on slippery
road), it automatically applies the braking force to
the slipping driving wheel. At the same time, TCL
reduces the engine output and prevents the
wheel spin when it determines that the engine
torque is too high for the road surface friction
coefficient.

• When the skid control function determines that

the vehicle behavior is in a critical state, it
reduces the engine output and applies brake
force to four wheels independently to control the
vehicle behavior, avoiding the critical state.

• Brake performance at ASC system failure is

ensured by the fail-safe function, and at the same
time, the serviceability during service is
improved.

NOTE:

.

•

*1

: For the details on twin clutch sportronic shift

transmission (TC-SST), refer to technical infor-
mation manual.

•

*2

: For the details on super all wheel control

(S-AWC), refer to technical information manual.

•

The active skid control (ASC) has the traction
control function and the skid control function. By
the integrated control with the anti-lock brake
system, the system stabilizes the vehicle attitude
and, at the same time, secures the driving force.
