Brake warning light

If the brake fluid level is below the minimum mark on the brake fluid reservoir, do not drive the vehicle until the brake system has been checked by a NISSAN dealer or qualified worksho
Even if you judge it to be safe, have your vehicle towed because driving it could be dangerous.
Depressing the brake pedal without the engine running and/or with a low brake fluid level could increase the stopping distance and require greater pedal travel distance and effort.
The brake warning light indicates a low brake fluid level of the brake system and an Anti-lock Braking System (ABS) malfunction.
Low brake fluid warning indicator
When the ignition switch is placed in the ON position, the brake warning light illuminates, and then turns off.
If the brake warning light illuminates while the engine is running, or while driving, and the parking brake is released, it may indicate the brake fluid level is low.
When the brake warning light illuminates while driving, stop the vehicle safely as soon as possible. Stop the engine and check the brake fluid level. If the brake fluid level is at the minimum mark, add brake fluid as necessary. (See
.)Anti-lock Braking System (ABS) warning indicator
When the parking brake is released and the brake fluid level is sufficient, if both the brake warning light and the Anti-lock Braking System (ABS) warning light illuminate, it may indicate the ABS is not functioning properly. Have the brake system checked, and if necessary repaired, by a NISSAN dealer or qualified workshop promptly. (See
