break MITSUBISHI MONTERO 1991 Owner's Manual

improperly.
CONSEQUENCE OF DEFECT:
The safety belts would not provide adequate protection to an occupant
in a vehicle crash.
CORRECTIVE ACTION:
Owners should promptly check the condition and operation of both front
safety belt buckles and carefully inspect the red release button for
any breaks or cracks. They should ensure that both buckles are
operating properly by inserting each latch plate into its buckle,
tugging on the belt to make sure the latch is securely locked, and
then pressing the release button. The latch plate should pop out of
the buckle when the button is pressed. If either release button shows
a sign of breaking or cracking or if either buckle fails to operate
properly, owners should promptly contact their authorized dealer to
schedule an appointment to have the buckle replaced or repaired, free
of charge. The manufacturer is developing a remedy designed to prevent
failure of the buttons that are not currently broken.
NOTE:
If your vehicle is presented to an authorized dealer on an agreed upon
service date and the remedy is not provided free of charge within a
reasonable time, please contact Mitsubishi at 1-800-222-0037. Also
contact the National Highway Traffic Safety Administration's Auto
Safety Hotline at 1-800-424-9393.
ADDITIONAL INFORMATION:
The National Highway Traffic Safety Administration operates Monday
through Friday from 8:00 AM to 4:00 PM, Eastern Time. For more
information call (800) 424-9393 or (202) 366-0123. For the hearing

The electrical system is protected against shorts by fuses
that are designed to fail, to prevent damage to the wire harness. The
fuse block is located under the instrument panel on the driver's side.
If a fuse is blown, locate the cause before replacing the fuse. Spare
fuses are contained in the fuse block.

for items requiring additional maintenance.
NOTE: This article contains scheduled maintenance service
information. Fluid types and capacities listed with each
service in this article are only those necessary to perform
that scheduled service. For specifications pertaining to
fluid capacities for the entire vehicle, fuse and circuit

CAUTIONS & WARNINGS
SUPPLEMENTAL RESTRAINT SYSTEM (AIR BAG)
NOTE: See the AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT Section.
Modifications or improper maintenance, including incorrect
removal and installation of the Supplemental Restraint System (SRS),
can adversely affect system performance. DO NOT cover, obstruct or
change the steering wheel horn pad in any way, as such action could
cause improper function of the system. Use only plain water when
cleaning the horn pad. Solvents or cleaners could adversely affect the
air bag cover and cause improper deployment of the system.
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all warnings and service precautions. See
appropriate AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT section.
CAUTION: Disconnect negative battery cable before servicing any air
bag system, steering column or passenger side dash
component. After any repair, turn ignition key to the ON
position from passenger's side of vehicle in case of
accidental air bag inflation

VEHICLE SPEED SENSOR
1) Vehicle Speed Sensor (VSS) is located in speedometer
assembly. Connect an ohmmeter between sensor terminals on back of
instrument panel. See Fig. 7 or 8.
2) Rotate speedometer cable. For each revolution of
speedometer cable, sensor should make and break continuity 4 times. If
ohmmeter reading does not fluctuate between continuity and no
continuity or if sensor does not make and break continuity 4 times for
each revolution, replace sensor.

that all of the engine control systems are operating as they were
designed to. Therefore, they are not the cause of the driveability
problem.

causes of a driveability problem.
1. THROTTLE VALVE AREA - Dirt or ice buildup causing rough idle and
stalling.
2. ENGINE IGNITION TIMING - Must be set with timing terminal
grounded.

9. TORQUE CONVERTER CONDITION - May cause very low power at breakaway
or high speed (Only 1 condition at a time).
10. FUEL CONTAMINATION - High alcohol or water content.
11. FUEL INJECTORS - Rough idle may be caused by injector wiring not
connected to correct injector.
12. ENGINE SECONDARY IGNITION CHECK - Abnormal scope patterns.
13. TECHNICAL SERVICE BULLETINS - Any that apply to vehicle.
14. All air intake piping and vacuum hoses must be in place and
secure. The proper air filter element must be used.
