Older children should be seated in the rear seat with
their seat belt properly worn, and with an appropri-
ate booster seat (including a booster cushion) if
needed.

The airbag control unit monitors the readiness of the electronic
parts of the system whenever the ignition switch is in the “ON”
or “START” position. These include all of the items listed
above and all related wiring.
The airbags will operate only when the ignition switch is in the
“ON” or “START” position. When the impact sensors detect a sufficient front or side impact
to deploy the airbag(s), the appropriate airbag(s) will be
deployed.
When airbags deploy, some smoke is released accompanied by
a loud noise. The smoke is not harmful, but do not intentionally
inhale the smoke as it may cause temporary irritation to people
with respiratory problems.
After deployment, the airbags will quickly deflate, so quickly
that some people may not even realize the airbags inflated.
Airbag inflation does not prevent the driver from seeing or
being able to steer the vehicle, and does not prevent people
from leaving the vehicle.10- Side airbag modules

12- Side impact sensors
CAUTION
!
Airbags inflate very quickly and with great force. In
certain situations, contact with an inflating airbag
may cause small cuts, abrasions, and bruises.

Event Data Recording
N00418600171
Your vehicle is equipped with an “EDR” - Event Data
Recorder which is capable of collecting and storing data in the
event of an airbag deployment.
The EDR may record the following information:

Condition of specific vehicle systems;

Diagnostic code(s)
Driver’s seat position sensor
N00417900180
The driver’s seat position sensor is attached to the seat rail and
provides the airbag control unit with information on the seat’s
fore-aft position. The airbag control unit controls deployment
of the driver’s front airbag in accordance with the information
it receives from this sensor.
If there is a problem involving the driver’s seat position sensor,
the SRS warning in the instrument panel will come on. Refer to
“SRS warning light/display” on page 2-46.
WA R N I N G
!
If the SRS warning comes on, have the vehicle
inspected by an authorized Mitsubishi Motors
dealer as soon as possible.
Please observe the following instructions to ensure
that the driver’s seat position sensor can operate
correctly.
• Adjust the seat to the correct position, and sit well
back against the seatback.
Refer to “Front seats” on page 2-3.
• Do not recline the seatback more than necessary
when driving.
• Do not place metallic objects or luggage under the
front seat.

If the vehicle is involved in a severe impact, have the
SRS sensor inspected by an authorized Mitsubishi
Motors dealer as soon as possible.

Passenger’s seat weight sensors
N00418000292
The passenger’s seat weight sensors are attached to the seat
rails and provide the airbag control unit with information
regarding the weight on the front passenger seat. The airbag
control unit controls deployment of the passenger’s front air-
bag in accordance with the information it receives from this
sensor.
The passenger’s front airbag will not deploy in an impact when
the weight on the seat is sensed to be less than approximately
66 pounds (30 kg). In this case, the passenger’s airbag off indi-
cator will come on.
Refer to “Passenger’s airbag off indicator” on page 2-45.
If there is a problem involving the passenger’s seat weight sen-
sors, the SRS warning in the instrument panel will come on.
Refer to “SRS warning light/display” on page 2-46.
WA R N I N G
!
If any of the following conditions occur, you should
immediately have your vehicle inspected by an
authorized Mitsubishi Motors dealer as soon as pos-
sible:
• The SRS warning does not initially come on when
the ignition switch is turned to the “ON” or
“START” position.
• The SRS warning does not go out after several sec-
onds.
• The SRS warning comes on while you are driving.

To ensure that the passenger’s seat weight sensors
can correctly sense the weight being applied to the
seat, observe the following instructions. Failure to
follow these instructions can adversely affect the
performance of the passenger’s airbag system.
• Adjust the seat to the correct position, and sit well
back against the seatback.
Refer to “Front seats” on page 2-3.
• Do not recline the seatback more than necessary.
• Never have more than one person (adult or child)
sitting on the seat.
• Do not place anything between the seat and the
floor console.
• Do not hang anything on the front passenger’s
seatback.
• Do not remove the head restraints.
• When attaching a child restraint system, secure it
firmly.
• Do not place luggage or other objects on the seat.
• Do not use a seat cover or a cushion.
• Do not modify or replace the seat and seat belt.
• Do not place luggage or other objects under the
seat.
• Do not place the floor mat on the seat rails.
• Do not expose the sensors to liquids or vapors.
• Do not subject the sensors to shock.
• Do not allow rear-seat occupants to push the front
passenger seat with their feet or force the front
passenger seat upward.WA R N I N G

Passenger’s airbag off indicator
N00418100251
The passenger’s airbag off indicator is located in the instru-
ment panel.
The indicator normally comes on when the ignition switch is
turned to the “ON” position and goes out a few seconds later.
In the following situations, the indicator will stay on to show
that the passenger’s front airbag is not operational.

The passenger’s seat weight sensors sense a weight of less
than approximately 66 pounds (30 kg) on the front passen-
ger seat.

The front passenger’s seat is not occupied.
When the weight applied to the front passenger seat is sensed
to be approximately 66 pounds (30 kg) or greater, the indicator
goes out to show that the passenger’s front airbag is opera-
tional.
WA R N I N G
!
If any of the following conditions occur, you should
immediately have the airbag system in your vehicle
inspected by an authorized Mitsubishi Motors
dealer as soon as possible:
• The passenger’s airbag off indicator comes on
when an adult is sitting on the front passenger
seat.
• The passenger’s airbag off indicator does not come
on when the front passenger’s seat is not occupied.
• The passenger’s airbag off indicator does not come
on when the ignition switch is turned to the “ON”
position.
• The passenger’s airbag off indicator comes on and
goes out repeatedly.

Do not attach any accessory to your vehicle that
makes the passenger’s airbag off indicator difficult
or impossible to see.
You must be able to see the passenger’s airbag off
indicator and verify the status of the passenger’s air-
bag system.

SRS warning light/display
N00408300524
Warning light
Warning display type 1
Warning display type 2
If there is an error in the system, the warning light will come on
and the warning display will appear on the information screen
in the multi-information display.
Under normal conditions, the warning light comes on when the
ignition switch is turned to the “ON” position and goes off a
few seconds later.
The warning light will also come on and remain on when the
SRS airbags and the seat belt pre-tensioner system have been
activated.
The warning light/display is used for both SRS airbag warn-
ings and seat belt pre-tensioner system warnings.
WA R N I N G
!
There may be a system error if the warning
light/display appears as indicated. In such cases, an
SRS airbag or a seat belt pre-tensioner system may
not function properly in a collision. Have your vehi-
cle checked by an authorized Mitsubishi Motors
dealer:
• Even when the ignition switch is in the “ON” posi-
tion, the warning light does not come on or it
remains on a few seconds later
• When warning light comes on while driving
• When warning display appears while driving

Driver’s and passenger’s front airbag system
N00407900275
The driver’s airbag is located under the padded cover in the
middle of the steering wheel. The front passenger’s airbag is
contained in the instrument panel above the glove compart-
ment. The driver’s airbag and the front passenger’s airbag are
designed to deploy at the same time. However, the front pas-
senger’s airbag does not deploy when the front passenger seat
is not occupied or when the weight sensor in the front passen-
ger seat senses a weight on the seat of less than approximately
66 pounds (30 kg).
Driver’s knee airbag system
N00404500010
The driver’s knee airbag is located under the steering wheel.
The driver’s knee airbag is designed to deploy at the same time
as the driver’s front airbag.
