- Always clean the filler cap area before removing the cap.

Brake fluid

Check the brake fluid level in the reservoir. If the level is below the MIN line 1, or if the brake warning light illuminates, add Genuine NISSAN Brake Fluid or equivalent DOT 3 or DOT 4 brake fluid up to the MAX line 2.
If brake fluid must be added frequently, the braking system should be inspected. It is recommended that you visit a NISSAN dealer for professional service.
Clutch fluid

Check the clutch fluid level in the reservoir. If the fluid is below the CL (clutch) MIN line 2, add Genuine NISSAN Brake Fluid or equivalent DOT 3 or DOT 4 fluid up to the MAX line 1.
If clutch fluid requires frequent replenishment, the clutch system should be checked. It is recommended that you visit a NISSAN dealer for this service.
