Maintenance Main Items
If the message ‘‘SERVICE’’ does not appear more than 12 months after the display is reset, change the engine oil every
year.
NOTE:


 Replace the brake fluid every 3 years independent of the maintenance messages in the information display.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2 or 3, only if they are noisy.

















A Replace engine oil (see page 8-10).
Engine oil capacity without oil filter:
K20Z2: 4.0 L (4.2 US qt)

K20Z2: 4.2 L (4.4 US qt)
K20Z3: 4.4 L (4.6 US qt)
Check front and rear brakes (see page 19-3). Check pad and disc for wear (thickness), damage, and cracks.
Check calipers for damage, leaks, and tightness of mounting bolts.
Check parking brake adjustment (see page 19-7). Check the number of clicks (8 to 10) when the parking brake lever is pulled with 196 N (20 kgf,
44 lbf) of force.
Inspect tie-rod ends, steering gearbox, and gearbox boots (see page 17-5). Check steering linkage.
Check boots for damage and leaking grease.
Check fluid lines for damage and leaks.
Inspect suspension components (see page 18-3). Check bolts for tightness.
Check condition of ball joint boots for deterioration and damage.

Inspect all fluid levels and condition of fluids. Engine coolant (see page 10-7)
Automatic transmission fluid (ATF-Z1) (see page 14-231)
Manual transmission fluid (MTF)
5M/T (see page 13-5), 6M/T (see page 13-82)
Clutch fluid (see page 12-7)
