PRECAUTIONS AND PREPARATION
LC-2

Oil Filter Bracket
OIL PUMP RELIEF VALVE INSPECTION
1. Visually inspect components for wear and damage.
2. Coat relief valve with engine oil and check that it falls
smoothly into the valve hole by its own weight.
If damaged, replace oil pump relief valve set.
OIL FILTER RELIEF VALVE INSPECTION
Inspect oil filter relief valve for rough movement and damage by
pushing the ball.
If damaged, replace oil filter bracket assembly.

PRE-DELIVERY INSPECTION ITEMS
MA-3

Depending on annual driving distance and engine types, different basic schedules are introduced here.
Please follow the appropriate schedule for the vehicle. Furthermore, according to the weather and atmo-
spheric conditions, varying road surfaces, individual driving habits and vehicle usage, additional or more
frequent maintenance may be required, as shown in ``Maintenance Under Severe Driving Conditions''.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
Basic Schedule for Gasoline Engine Models
Engine maintenance for vehicles which drive less than 30,000 km/year (18,000 miles/year)
