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.
