perform regular checks. Toyota recommends the following main-  
tenance:  
General maintenance  
General maintenance should be performed on a daily basis. This can  
be done by yourself or by a Toyota dealer.  
Scheduled maintenance  
Scheduled maintenance should be performed at specified intervals  
according to the maintenance schedule.  
For details about maintenance items and schedules, refer to the “Sched-  
uled Maintenance Guide” or “Owner’s Manual Supplement”.

The use of Toyota Repair Manuals is recommended.  
For details about warranty coverage, refer to the separate “Owner’s War-  
ranty Information Booklet” or “Owner’s Manual Supplement”.  
Repair and replacement  
It is recommended that genuine Toyota parts be used for repairs to ensure  
performance of each system. If non-Toyota parts are used in replacement or if  
a repair shop other than a Toyota dealer performs repairs, confirm the war-  
ranty coverage.

6-2. Maintenance  
Emission inspection and maintenance (I/M)  
programs  
Some states have vehicle emission inspection programs which  
include OBD (On Board Diagnostics) checks. The OBD system  
monitors the operation of the emission control system.  
If the malfunction indicator lamp comes on  
The OBD system determines that a problem exists somewhere in the  
emission control system. Your vehicle may not pass the I/M test and  
may need to be repaired. Contact your Toyota dealer to service the  
vehicle.  
Your vehicle may not pass the I/M test in the following situations:  
When the battery is disconnected or discharged  
Readiness codes that are set during ordinary driving are erased.  
Also, depending on your driving habits, the readiness codes may  
not be completely set.  
When the fuel tank cap is loose  
The malfunction indicator lamp comes on indicating a temporary  
malfunction and your vehicle may not pass the I/M test.  
When the malfunction indicator lamp still remains on after sev-  
eral driving trips  
The error code in the OBD system will not be cleared unless the vehi-  
cle is driven 40 or more times.  
If your vehicle does not pass the I/M test  
Contact your Toyota dealer to prepare the vehicle for re-testing.
