allowing metal objects to contact the battery posts and the
vehicle at the same time.
CAUTION: Never disconnect the battery while the engine is running;
doing so could damage the car's electrical components.
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical system. Be
sure to use fuse with the correct indicated amperage rating. The use
of an incorrect amperage rating fuse may result in a dangerous
electrical system overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.
BRAKE FLUID
WARNING: DO NOT use reclaimed fluid or fluid that has been stored
in old or open containers. It is essential that foreign
particles and other liquids are kept out of the brake fluid
reservoir.
CATALYTIC CONVERTER
Continued operation of vehicle with a severe malfunction
could cause converter to overheat, resulting in possible damage to
converter and vehicle.
ENGINE COOLANT SERVICE
WARNING: To avoid the danger of being scalded never change the coolant
when the engine is hot.
WARNING: Never remove the radiator cap when the engine is hot Serious
burns could be caused by high pressure fluid escaping from
the radiator.
CAUTION: When adding or replacing engine coolant, use a high quality
ethylene glycol antifreeze diluted with 50% distilled water.
When putting the cap on the reserve tank, line up the arrow
on the cap and the arrow on the tank, or coolant can leak out
ENGINE DRIVE BELT SERVICE
WARNING: Be sure the ignition key is OFF. The engine could rotate
unexpectedly.
ENGINE OIL
WARNING: The engine oil may be high enough to burn your fingers
when the drain plug is loosened. Wait until the drain plug
is cool enough to touch with you bare hands.
WARNING: Continuous contact with used engine oil has been found to
cause skin cancer in laboratory animals. Brief contact with
used engine oil may irritate skin. To minimize your exposure
to used oil, wear a long sleeve shirt and moisture-proof
gloves when changing oil. If oil contacts your skin, wash

thoroughly with soap and water.
CAUTION: Never use non-detergent or straight mineral oil.
FUEL SYSTEM SERVICE
WARNING: Relieve fuel system pressure prior to servicing any fuel
system component (fuel injection models).
HALOGEN BULBS
Halogen bulbs contain pressurized gas which may explode if
overheated. DO NOT touch glass portion of bulb with bare hands. Eye
protection should be worn when handling or working around halogen
bulbs.
RADIATOR CAP
CAUTION: Always disconnect the fan motor when working near the
radiator fan. The fan is temperature controlled and could
start at any time even when the ignition key is in the OFF
position. DO NOT loosen or remove radiator cap when cooling
system is hot.
RADIATOR FAN
WARNING: Keep hands away from radiator fan. Fan is controlled by a
thermostatic switch which may come on or run for up to 15 minutes even
after engine is turned off.
WARRANTY INFORMATION
CAUTION: Due to the different warranties offered in various regions
and the variety of after-market extended warranties
available, please refer to the warranty package that came
with the vehicle to verify all warranty options.
FUSES & CIRCUIT BREAKERS
FUSE PANEL LOCATION
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.

SCHEDULED SERVICES
1998 Mitsubishi Montero
1997-98 MAINTENANCE
Mitsubishi Maintenance & Service Intervals
Mitsubishi: Montero
* READ THIS FIRST *
Before preforming maintenance on vehicle, ensure that all
cautions and warnings have been observed to prevent vehicle damage or
personal injury. See CAUTIONS & WARNINGS in MAINTENANCE INFORMATION
article in this section.
Introduction
The frequency of scheduled inspection and maintenance
services in this article are based on "normal" vehicle usage. They DO
NOT take into account the following "severe" conditions:
* Driving In Dusty Conditions
* Trailer Towing, Police, Taxi, commercial Type Operation
* Extensive Idling, Driving In Stop-And-Go Traffic
* Short Trip Operation At Freezing Temperatures (Engine Not
Thoroughly Warmed Up)
* Driving In Sandy Areas
* Driving In Salty Areas
* More Than 50% Operation In Heavy City Traffic Or At Sustained
High Speeds During Hot Weather Above 90
F (32C)
* Driving On Off-Road
If any of these severe conditions exist, the "normal" service
schedule frequency for some service items is inadequate and must be
supplemented. See the following section for specific details,
SEVERE SERVICE CONDITIONS/ACTIONS .
SEVERE SERVICE CONDITIONS/ACTIONS
The following table identifies eight "severe" conditions that
cause faster-than-normal wear. Each condition lists affected service
item(s) and their revised (more frequent) service interval.
If any severe condition(s) is applicable, its revised service\
interval(s) supersede those found in the "normal" schedules. Depending\
on the specific mileage/time, the revised interval(s) may overlap a
normal schedule (in which case they can be done together). If not, it
must be performed outside of the normal schedule.
