2012 MITSUBISHI GALANT sensor

1-2 General information
1Fuel selection
N00301000794
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 unleaded gasoline hav-
ing a minimum octane number of 87 [(MON+RON)/2], or 91
RON.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 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. Methanol Do not operate your vehicle on gasoline containing methanol
(wood alcohol). Using this type of alcohol could adversely
affect the vehicle’s performance and damage critical parts of
the vehicle’s fuel system. Reformulated gasoline Many areas of the country require the use of cleaner burning
fuel referred to as “Reformulated Gasoline”.
Reformulated gasoline contains oxygenates and is specially
blended to reduce vehicle emissions and improve air quality.
Mitsubishi Motors Corporation strongly supports the use of
reformulated gasoline. Properly blended reformulated gasoline
has no adverse effect on vehicle performance or on the durabil-
ity of the engine and fuel system.
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.

The seat belt pre-tensioner system includes the following com-
ponents:
The air bag 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 belts 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.
Even in the event of a severe frontal impact, the pre-tensioners
will not operate if the seat belts are not fastened. The seat belt
pre-tensioners may not activate in certain frontal collisions,
even though the vehicle may appear to be severely damaged.
Such non-activation does not mean something is wrong with
the seat belt pre-tensioner system, but rather that the collision
forces were not severe enough or not of the type to activate 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.

2Supplemental Restraint System (SRS) - air
bag
N00407700677
This vehicle is equipped with a Supplemental Restraint System
(SRS), which includes air bags for the driver and passengers.
The SRS front air bags 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 driver and front passenger air bags, together with sen-
sors at the front of the vehicle and sensors attached to the front
seats, form an advanced air bag system.
The SRS side air bags are also designed to supplement the seat
belts and provide the driver and front passenger with protection
against chest and abdomen injuries in certain moderate to
severe side impact collisions.
The SRS curtain air bags are designed to supplement the seat
belts and provide the driver and passengers with protection
against head injuries in certain moderate-to-severe side impact
collisions.
The SRS air bags 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 in the rear seat, and older children buckled in the
rear seat). Refer to “Child restraints” on page 2-27.
WA R N I N G
!
IT IS VERY IMPORTANT TO ALWAYS WEAR
YOUR SEAT BELT PROPERLY EVEN WITH AN
AIR BAG.
• 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 air bags 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 air bag when
it begins to inflate.
The beginning stage of air bag inflation is the most
forceful and can cause serious injuries or death if
the occupant comes in contact with the air bag at
this time.
• Seat belts reduce the risk of injury in rollovers,
rear impact collisions, and in lower-speed frontal
collisions, because the air bags are not designed to
inflate in those situations.
• Seat belts reduce the risk of being thrown from
your vehicle in a collision or rollover.

How the Supplemental Restraint System works
N00407800173
The SRS includes the following components:
WA R N I N G
!
FRONT-FACING CHILD RESTRAINTS should be
used in the rear seat whenever possible. If they must
be used in the front passenger seat, move the seat to
the most rearward position and make sure the child
stays in the child restraint, properly restrained. Fail-
ure to follow these instructions could result in seri-
ous injury or death to the child.
WA R N I N G
!
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.
Refer to “Children who have outgrown child
restraint systems” on page 2-36.

The air bag 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 air bags 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 air bag(s), the appropriate air bag(s) will be
deployed.
When air bags 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 air bags will quickly deflate, so quickly
that some people may not even realize the air bags inflated. Air
bag inflation does not prevent the driver from seeing or being
able to steer the vehicle, and does not prevent people from
leaving the vehicle.9- Side air bag modules
10- Curtain air bag modules
11- Side impact sensors
CAUTION
!
Air bags inflate very quickly and with great force. In
certain situations, contact with an inflating air bag
may cause small cuts, abrasions, and bruises.

Event Data Recording
N00418600054
Your vehicle is equipped with an “EDR” - Event Data
Recorder which is capable of collecting and storing data in the
event of an air bag deployment.
The EDR may record the following information:

Condition of specific vehicle systems;

Whether the driver and front passenger seat belts were
buckled;

Diagnostic code(s)
Driver’s seat position sensor
N00417900092
The driver’s seat position sensor is attached to the seat rail and
provides the air bag control unit with information on the seat’s
fore-aft position. The air bag control unit controls deployment
of the driver’s front air bag 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 light in the instrument panel will come on.
Refer to “SRS warning light” on page 2-46.
WA R N I N G
!
If the SRS warning light 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 seat” on page 2-4.
• 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
sensor inspected by an authorized Mitsubishi
Motors dealer as soon as possible.

Passenger’s seat weight sensors
N00418000087
The passenger’s seat weight sensors are attached to the seat
rails and provide the air bag control unit with information
regarding the weight on the front passenger seat. The air bag
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 air bag will not deploy in an impact
when the weight on the seat is sensed to be less than approxi-
mately 66 pounds (30 kg). In this case, the passenger’s air bag
off indicator will come on.
Refer to “Passenger’s air bag off indicator” on page 2-45.
If there is a problem involving the passenger’s seat weight sen-
sors, the SRS warning light in the instrument panel will come
on. Refer to “SRS warning light” 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 light does not initially come on
when the ignition key is turned to the “ON” or
“START” position.
• The SRS warning light does not go out after sev-
eral seconds.
• The SRS warning light 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 air bag system.
• Adjust the seat to the correct position, and sit well
back against the seatback.
Refer to “Front seat” on page 2-4.
• 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.
• 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.WA R N I N G

Passenger’s air bag off indicator
N00418100088
The passenger’s air bag off indicator is located above the cen-
tral vents in the instrument 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 air bag 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 air bag is opera-
tional.

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