PERIODIC MAINTENANCE
Introduction of Periodic MaintenanceINFOID:0000000006287729
Two different maintenance schedules are provided, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage/time intervals.
Schedule 1INFOID:0000000006287730
EMISSION CONTROL SYSTEM
Abbreviations: R = Replace. I = Inspec t. Correct or replace if necessary. [ ]: At the mileage intervals only
Schedule 1Follow Periodic Maintenance Schedule 1 if the driving habits frequently include
one or more of the following driving conditions:
 Repeated short trips of less than 5 miles (8 km).
 Repeated short trips of less than 10 miles (16 km) with outside temperatures
remaining below freezing.
 Operating in hot weather in stop-and-go “rush hour” traffic.
 Extensive idling and/or low speed driving for long distances, such as police, taxi
or door-to-door delivery use.
 Driving in dusty conditions.
 Driving on rough, muddy, or salt spread roads.
 Towing a trailer, using a camper or a car-top carrier. Emission Control Sys-

OIL PRESSURE WARNING LAMP : System Description
INFOID:0000000006221709
 IPDM E/R reads the ON/OFF signals fr om the oil pressure switch and transmits the oil pressure switch sig-
nal to the combination meter via BCM with the CAN communication.
 The combination meter turns the oil pressure warning lamp ON (at the time of a reduction in hydraulic pres-
sure)/OFF (except at the time of a reduction in hydraulic pressure) according to the oil pressure switch signal
received via CAN communication.

 The ambient sensor input value that is displayed on “Data Monitor” of CONSULT-III is the value before the
correction. It may not match the indica ted temperature on the information display.
 After removal and installation of the battery and comb ination meter, an ambient sensor-detected tempera-
ture is indicated on the information display.
 Depending on engine heat or heat on the road surfaces, an ambient temperature may be indicated higher
than actual one.
INTERRUPT INDICATION
 The combination meter displays an interrupt regarding a warning, alert, and maintenance on the information
display, based on signals received from each unit and switch.
 When conditions are satisfied, the normal screen swit ches to a warning screen to display an interrupt.
Door Open Warning
 When all the following operating conditions are satisfied, the combination meter displays a door open warn-
ing on the information display by an interrupt.
 The combination meter judges showing/hiding of “door open warning”, according to the signals below:
