Inspection
WARNING
In principle, the transmission oil is maintenance-free, and no exchange is required.
But it must be inspected and replenished every 4 years or 40,000 miles.
- Uplift the vehicle with lift.
- Remove the engine room under cover.
(Refer to Engine Mechanical System - "Engine Room Under Cover")
- Loosen the oil filler plug (A).
- Check the oil level.
WARNING
- For the accuracy, inspect the oil level after the oil is completely drained.
- Loosen the drain plug (A) and wait for over 10 minutes until the oil is drained enough.
- Install the drain plug (A) after drain the oil.
- After the inspection, inject the oil through the filler plug
hole according to the specification.
(Specified fluid : 1.6 - 1.7L (0.42 - 0.45\j.S.gal., 1.69 -1.80 U.S. qt., 1.41 - 1.50 Imp qt)
- While draining, some of the oil flows into the transmission
part and the oil may be less than the
specification by 0.1 - 0.15 L (0.03 - 0.04 U.S.gal., 0.10 - 0.16 U.S. qt.,
0.09 - 0.13 Imp qt.) This is normal
and additional oil injection is not required.
- The existing gasket (A) must be replaced with a new one. (Do not reuse it.)
New gasket part no.: 45323-39000
- Install the filler plug (A) with new gasket.
Tightening torque : 58.9 - 78.5 N.m (6.0 - 8.0 kgf.m. 43.4 - 57.8 lb-ft)
WARNING
The existing gasket (A) must be replaced with a new one. (Do not
reuse it.) 
- Install the engine room under cover.
