1-2 General information
1Fuel selection
N00301000879
Your vehicle is designed to use unleaded gasoline only. It is
equipped with a fuel filler tube especially designed to accept
only a small diameter unleaded gasoline dispensing nozzle. Gasoline detergent additivesIn the United States, fuel suppliers are required by law to add
detergents to their gasoline to minimize fuel-injector fouling
and minimize intake-valve deposits. Detergent gasoline helps
keep your engine in tune and your emission-control system
working properly.
Octane requirementYour vehicle is designed to operate on premium grade
unleaded gasoline having a minimum octane number of 93
[(MON+RON)/2] or higher for optimum performance. In case
premium grade unleaded gasoline 93 [(MON+RON)/2] is not
available, unleaded gasoline rating of 91 [(MON+RON)/2] can
be used. However, the performance level is reduced.
In order to maintain exhaust system durability, premium
unleaded gasoline having an octane number of at least 91
[(MON+RON)/2] must be used
If the premium grade unleaded gasoline rating of 91
[(MON+RON)/2] or higher is not available on journey, etc.,
regular unleaded gasoline having an octane number of 87
[(MON+RON)/2] can be used temporarily as an emergency
measure.
MON: Motor Octane Number
RON: Research Octane Number Oxygenated gasoline Gasoline sold at some service stations contains oxygenates
such as ethanol, although the oxygenates may not be identified
by those names. Oxygenates are required in some areas of the
country. Such fuel can be used in your vehicle.Ethanol (Gasohol) A mixture of up to 10 % ethanol (grain alcohol) and 90 %
unleaded gasoline may be used in your vehicle, provided the
octane number is at least as high as that recommended for
unleaded gasoline.
WA R N I N G
!
Gasoline is highly flammable and explosive. You
could be burned, seriously injured or killed when
handling it. Whenever you refuel your vehicle, stop
the engine and keep flames, sparks, and smoking
materials away from the vehicle. Always handle fuel
in well-ventilated outdoor areas.
CAUTION
!
Using leaded gasoline in your vehicle will damage
the engine, catalytic converter, and the oxygen sen-
sors. Also, using leaded gasoline is illegal, and will
void your warranty coverage of the engine, catalytic
converter, and oxygen sensors.

2Seat belt pre-tensioner and force limiter
systems
N00417700638
The driver’s and front passenger’s seats each have a seat belt
equipped with a pre-tensioner system.Pre-tensioner system The driver and front passenger seat belts are equipped with a
seat belt pre-tensioner system. In a moderate-to-severe frontal
or side collision, the pre-tensioner system operates simulta-
neously with the deployment of the front airbags or side air-
bags and curtain airbags.
The seat belt pre-tensioners are located within the seat belt
retractors (A). When activated, the pre-tensioners quickly draw
back seat belt webbing and increase seat belt performance.The seat belt pre-tensioner system includes the following com-
ponents:
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 pre-tensioner seat belt system will operate only when the
ignition switch is in the “ON” or “START” position.

2 Supplemental Restraint System (SRS) -
airbag
N00407700651
This vehicle is equipped with a Supplemental Restraint System
(SRS), which includes airbags for the driver and passengers.
The SRS front airbags are designed to supplement the primary
protection of the driver and front passenger seat belt systems
by providing those occupants with protection against head and
chest injuries in certain moderate to severe frontal collisions.
The SRS front airbags, together with sensors at the front of the
vehicle and sensors attached to the front seats, form an
advanced airbag system.
The SRS driver’s knee airbag is designed to supplement the
primary protection of the driver’s seat belt system. It can
reduce the forward movement of the driver’s lower legs and
provide increased overall body protection in certain moderate
to severe frontal collisions.
The SRS side airbags and the curtain airbags are also designed
to supplement the seat belts. The SRS side airbags provide the
driver and front passenger with protection against chest injuries
by deploying the bag on the side impacted in moderate to
severe side impact collisions. The SRS curtain airbags provide
the driver and passengers on the front seat and rear outboard
seat with protection against head injuries by deploying a bag
on the side impacted in moderate to severe side impact colli-
sions.The SRS airbags are NOT a substitute for use of the seat belts.
For maximum protection in all types of accidents, seat belts
must ALWAYS be worn by everyone who drives or rides in
this vehicle (with infants and small children in an appropriate
child restraint system in the rear seat, and older children buck-
led in the rear seat). Refer to “Child restraint systems” on page
2-22.
WA R N I N G
!
IT IS VERY IMPORTANT TO ALWAYS WEAR
YOUR SEAT BELT PROPERLY EVEN WITH AN
AIRBAG.
• Seat belts help keep the driver and passengers
properly positioned. This reduces the risk of injury
in all collisions, and reduces the risk of serious
injuries or death when the airbags inflate.
During sudden braking just before a collision, an
unrestrained or improperly restrained driver or
passengers can move forward into direct contact
with, or within close proximity to, the airbag when
it begins to inflate.
The beginning stage of airbag inflation is the most
forceful and can cause serious injuries or death if
the occupant comes in contact with the airbag at
this time.
• Seat belts reduce the risk of injury in rollovers,
rear impact collisions, and in lower-speed frontal
collisions, because the airbags are not designed to
inflate in those situations.
• Seat belts reduce the risk of being thrown from
your vehicle in a collision or rollover.

When the impact sensors detect a front or side impact sufficient
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.
Event Data Recording
N00418600230
This vehicle is equipped with an event data recorder (EDR).
The main purpose of an EDR is to record, in certain crash or
near crash-like situations, such as an airbag deployment or hit-
ting a road obstacle, data that will assist in understanding how
a vehicle’s systems performed.
The EDR is designed to record data related to vehicle dynam-
ics and safety systems for a short period of time, typically 30
seconds or less.
The EDR in this vehicle is designed to record such data as:

How various systems in your vehicle were operating;

Whether or not the driver and passenger safety belts were
buckled/fastened;

How far (if at all) the driver was depressing the accelera-
tor and/or brake pedal; and,

How fast the vehicle was traveling.
These data can help provide a better understanding of the cir-
cumstances in which crashes and injuries occur.
CAUTION
!
Airbags inflate very quickly and with great force. In
certain situations, contact with an inflating airbag
may cause small cuts, abrasions, and bruises. Refer
to “Supplemental Restraint System (SRS) - airbag”
on page 2-33.

NOTE
EDR data are recorded by your vehicle only if a non-triv-
ial crash situation occurs; no data are recorded by the
EDR under normal driving conditions and no personal
data (e.g., name, gender, age, and crash location) are
recorded. However, other parties, such as law enforce-
ment, could combine the EDR data with the type of per-
sonally identifying data routinely acquired during a crash
investigation.
To read data recorded by an EDR, special equipment is
required, and access to the vehicle or the EDR is needed. In
addition to the vehicle manufacturer, other parties, such as law
enforcement, that have the special equipment, can read the
information if they have access to the vehicle or the EDR.
Driver’s seat position sensor
N00417900193
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 2-42.
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
N00418000306
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
airbag 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 2-41.
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 2-42.
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.
• 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.

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.
• Do not allow rear-seat occupants to grasp the front
passenger’s seatback or put their arms around it.
• When attaching a child restraint system in the rear
seat, make sure it does not interfere with the front
seat.

If the vehicle is involved in a severe impact, have the
SRS sensors inspected by an authorized Mitsubishi
Motors dealer as soon as possible.WA R N I N G
