WHEEL & TIRE SPECIFICATIONS
Tire specifications are imprinted on the tire side wall. The
recommended cold tire inflation pressures are listed on a label
attached to the rear face of the driver's door. These pressures
provide the best combination of ride comfort, tire wear and stability
under normal conditions.
CAUTION: DO NOT mix tires of different design such as radial ply
with bias or bias-belted tires. Mixing tire types will
adversely affect road handling and may lead to loss of
vehicle control. When using snow tires, they must be used
in set of four for maneuverability and safety. DO NOT use
tire chains on front wheels.

BATTERY SPECIFICATIONS
CAUTION: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure. See
COMPUTER RELEARN PROCEDURES article in the GENERAL
INFORMATION Section.
Battery is maintenance-free and does not normally require
additional water. However, under severe conditions it is advisable to
check battery fluid periodically. Use only distilled water to fill
battery cell should it become necessary to add water. Charge condition
can be checked by a visual test indicator on top of battery.

CAUTIONS & WARNINGS
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR BAG SYSTEM
NOTE: See the AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT Section.
The SRS has no user-servicable parts. Always have servicing
done by an authorized dealer.
When performing maintenance on air bag equipped vehicles
always observe proper safety precautions.
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
ANTI-LOCK BRAKE SYSTEM (ABS)
CAUTION: Never mix different diameter tires. On loose or uneven
surfaces, the ABS system may require longer stopping
distances than conventional brake systems. Exercise caution
when removing mud or snow from the wheels so as not to
damage the ABS wiring or speed sensors.
BATTERY WARNING
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure. See
appropriate COMPUTER RELEARN PROCEDURES article in the
GENERAL INFORMATION section below.
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.

MITSUBISHI MONTERO 1991 Service Manual CATALYTIC CONVERTER
Continued operation of vehicle with a severe malfunction
could cause converter to overheat, resulting in possible damage to
converter and vehicle.
COOLAN

CATALYTIC CONVERTER
Continued operation of vehicle with a severe malfunction
could cause converter to overheat, resulting in possible damage to
converter and vehicle.
COOLANT (PROPYLENE-GLYCOL FORMULATIONS)
CAUTION: To avoid possible damage to vehicle use only ethylene-glycol
based coolants with a mixture ratio from 44-68% anti-freeze.
DO NOT use 100% anti-freeze as it will cause the formation
of cooling system deposits. This results in coolant
temperatures of over 300
\b F (149\bC) which can melt plastics.
100% anti-freeze has a freeze point of only -8\b F (-22\bC).
CAUTION: Propylene-Glycol Mixtures has a smaller temperature range
than Ethylene-Glycol. The temperature range (freeze-boil)
of a 50/50 Anti-Freeze/Water Mix is as follows:
Propylene-Glycol -26
\b F (-32\bC) - 257\b F (125\bC)
Ethylene-Glycol -35\b F (-37\bC) - 263\b F (128\bC)
CAUTION: Propylene-Glycol/Ethylene-Glycol Mixtures can cause the
destabilization of various corrosion inhibitors. Also
Propylene-Glycol/Ethylene-Glycol has a different specific
gravity than Ethylene-Glycol coolant, which will result in
inaccurate freeze point calculations.
ELECTROSTATIC DISCHARGE SENSITIVE (ESD) PARTS
WARNING: Many solid state electrical components can be damaged by
static electricity (ESD). Some will display a warning label,
but many will not. Discharge personal static electricity by
touching a metal ground point on the vehicle prior to
servicing any ESD sensitive component.
ENGINE OIL
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
WARNING: 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

Page 672 of 1333

MITSUBISHI MONTERO 1991 Service Manual 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.
