242SRS
*The SRS airbag are provided for the driver and front passenger. The SRS airbags have been designed to help reducing
the shocks to the heads and chests of the driver and front passenger in the event of a severe frontal impact collision as
supplements to the seat belts.
This system is a 3-sensor type airbag system to detect the impact during a front collision using the center airbag sensor
assembly and airbag sensor front LH, RH, and to make the airbag system and pretensioner operate as well.
*In this system, a front side collision is detected by the side airbag sensor front LH, RH in order to simultaneously deploy
the side and curtain shield airbags. A rear side collision is detected by the side airbag sensor rear LH, RH in order to
deploy only the curtain shield airbag.
*Roll sensing of curtain shield airbags control has been adopted in order to deploy the curtain shield airbags and the
pretensioners for the driver and front passenger, in the event that the vehicle rolls over.
A roll sensing of curtain shield airbags cutoff SW is provided on the driver side of the instrument panel to enable the driver
to disable this system.
*Dual-stage SRS airbags system, that controls the airbag inflating output optimum by judging the extent of impact and seat
position (Driver seat), has been used for the driver and front passenger airbags.
*In accordance with the adoption of the dual-stage SRS airbag system, a seat position sensor has been established for the
driver seat.
*This system has adopted a fuel cut control that stops the fuel pump when the airbag is deployed.

254Power Window
1. Manual Down or Up Operation
When the power window master SW is pressed one step, the current flows from the power window master SW TERMINAL
DN to the power window motor front LH to the power window master SW TERMINAL UP to GROUND, and rotates the motor
to open the window.
When the power window master SW is pulled one step, the current flows from the power window master SW TERMINAL UP
to the power window motor front LH to the power window master SW TERMINAL DN to GROUND, and rotates the motor to
close the window.
For the other windows, as the power window master SW and the power window SW is operated, the relevant door window is
opened or closed.
2. Auto Down or Up Operation
When the power window master SW is pushed two steps, the power window master SW determines it is in auto mode and
the current flows from the power window master SW TERMINAL DN to the power window motor front LH to the power
window master SW TERMINAL UP to GROUND, and rotates the motor to open the window automatically.
When the power window master SW is pulled two steps, the power window master SW determines it is in auto mode and the
current flows from the power window master SW TERMINAL UP to the power window motor front LH to the power window
master SW TERMINAL DN to GROUND, and rotates the motor to close the window automatically.
Accordingly, when each window switch of the power window control SW is operated, the relevant door window is
automatically opened/closed.
3. Catching Prevention Function
When any foreign matter is caught in the window during power window up operation, the pulse sensor in the power window
motor detects the changes in the number of motor rotations and forcibly opens the door window 50 mm, or when the window
opening is less than 200 mm, it opens the window until the opening is 200 mm.
4. Key Off Power Window Operation
It is possible to operate the power window for approx. 43 seconds after the ignition SW is turned from on to off. However,
when the door is opened while the window is being operated, the power window operation is stopped even though 43
seconds have not elapsed.

321
When the ignition SW turned on, a signal is input to the combination meter and the center cluster integration panel (w/
navigation system) or the A/C control assembly (w/o navigation system). To determine whether the driver has fastened the
seat belt, a signal is input from the buckle SW LH to the combination meter. When the seat belt is not fastened, the seat belt
warning light in the combination meter blinks, and emits a warning sound.
In addition, the front passenger is recognized by a sensor (Seat belt warning occupant detection sensor) is installed in the
front passenger seat, and determines whether the seat belt is fastened. When not fastened, the signals from the seat belt
warning occupant detection sensor and the buckle SW RH is input to the center cluster integration panel (w/ navigation
system) or the A/C control assembly (w/o navigation system), and the passenger seat belt warning light blinks to warn the
passenger.
