1-2 General information
1Fuel selection
N00301000781
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 and MTBE, 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.

!

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.

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.When the seat belt pre-tensioners activate, some smoke is
released and a loud noise will be heard. The smoke is not harm-
ful, but care should be taken not to intentionally inhale it, as it
may cause some temporary irritation to people with respiratory
problems.
The pre-tensioners activate in the event of moderate-to-severe
frontal impact, even if the seat belt is not being worn. The seat
belt pre-tensioners may not activate in certain frontal colli-
sions, even though the vehicle may appear to be severely dam-
aged. Such non-activation does not mean something is wrong
with the seat belt pre-tensioner system, but rather that the colli-
sion forces were not severe enough or not of the type to acti-
vate the system.1- SRS warning light

The seat belt pre-tensioner system is designed to
work only once. After the seat belt pre-tensioners
have been activated, they will not work again. They
must promptly be replaced and the entire seat belt
pre-tensioner system inspected by an authorized
Mitsubishi Motors dealer.

2Maintenance and inspection of seat belts
N00407000221
The seat belt webbing may be cleaned with mild soap or deter-
gent solution. Do not use an organic solvent. Allow the belts to
dry in the shade. Do not allow them to retract until completely
dry. Do not attempt to bleach or re-dye the belts. The color may
rub off and the webbing strength may be affected.
Regularly check your seat belt buckles and their release mech-
anisms for positive engagement and release of the latch plate.
Check the retractors for automatic locking when in the Auto-
matic Locking Retractor function.
The entire seat belt assembly should be replaced if the webbing
shows any obvious cuts, tears, increase in thickness in any sec-
tion of the webbing from broken fibers, or severe fading from
sunlight. All of these conditions indicate a weakening of the
belt, which may adversely affect seat belt performance in an
accident.
Supplemental Restraint System (SRS) - air-
bag
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.
WA R N I N G
!

Do not attempt to repair or replace any part of the
seat belt assemblies. This work should be done by an
authorized Mitsubishi Motors dealer. Failure to
have an authorized Mitsubishi Motors dealer per-
form the work could reduce the effectiveness of the
belts and could result in a serious injury or death in
an accident.

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

CAUTION
!

Airbags inflate very quickly and with great force. In
certain situations, contact with an inflating airbag
may cause small cuts, abrasions, and bruises.

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 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 2-41.
If there is a problem involving the passenger’s seat weight sen-
sors, the SRS warning in the instrument panel will come on.
