IDENTIFICATION NUMBER
Nissan has assigned identification number P0A08 to this campaign. This number must
appear on all communication and documentation of any nature dealing with this campaign.

DEALER RESPONSIBILITY
Dealers are to repair vehicles falling within range of this campaign that enter the service
department. This includes vehicles purchased from private parties, vehicles presented by
transient (tourists) owners, and vehicles in a dealer’s inventory.

properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

To prevent damage to the vehicle, never spill or splash brake fluid on painted surfaces.
Brake fluid may seriously damage paint. Wash with water if it gets on a painted surface.
6.

Drain the brake fluid from brake fluid reservoir as follows:
IMPORTANT: Monitor the level in the brake fluid reservoir while performing step 6.
Do not allow it to go below the minimum (MIN) line.
