Fluid specifications
- Engine oil: The workshop manual p. 9 specifies 10W-40, SL grade or higher: 1.6 L without a filter change, 1.7 L with a filter change, and 2.2 L after engine disassembly.
- Coolant: p. 35 specifies 1.3 L and the designation G40. Its accompanying wording is “Ethanol-containing, silicate-free coolant”; the designation is reproduced here without interpreting that chemistry description.
- Brake fluid: The front brake specification on p. 54 and rear brake specification on p. 55 both specify DOT 4.
Oil-level check timing: On p. 9, the main procedure says to idle for 180–300 seconds, stop the engine and wait one minute. The “Important” note on the same page covers the re-check after topping up: idle for 30 seconds, then check the level again.
Conflicting instructions in this manual
Rear shock absorber lower mounting bolt: The workshop manual specifies 35 N·m on p. 8, but 40 N·m for both upper and lower mounting bolts on p. 48. We cannot verify which lower-bolt value is correct.
