or Brake warning light

This light functions for both the parking brake and the foot brake systems.

Parking brake indicator (if so equipped)

When the ignition switch is placed in the ON position, the light comes on when the parking brake is applied.

Low brake fluid warning light

When the ignition switch is placed in the ON position, the light warns of a low brake fluid level. If the light comes on while the engine is running with the parking brake not applied, stop the vehicle and perform the following:

1. Check the brake fluid level. Add brake fluid as necessary. For additional information, see "Brake fluid".

2. If the brake fluid level is correct, have the warning system checked. It is recommended that you visit a NISSAN dealer for this service.

WARNING

• Your brake system may not be working properly if the warning light is on.

  Driving could be dangerous. If you judge it to be safe, drive carefully to the nearest service station for repairs.

  Otherwise, have your vehicle towed because driving it could be dangerous.

• Pressing the brake pedal with the engine stopped and/or a low brake fluid level may increase your stopping distance and braking will require greater pedal effort as well as pedal travel.
• If the brake fluid level is below the MINIMUM or MIN mark on the brake fluid reservoir, do not drive until the brake system has been checked.

  It is recommended that you visit a NISSAN dealer for this service.

Charge warning light

If this light comes on while the engine is running, it may indicate the charging system is not functioning properly. Turn the engine off and check the generator belt. If the belt is loose, broken, or missing, or if the light remains on, have the system checked.

It is recommended that you visit a NISSAN dealer for this service.

CAUTION

• Do not ground electrical accessories directly to the battery terminal. Doing so will bypass the variable voltage control system and the vehicle battery may not charge completely.

  For additional information, see "Variable voltage control system".

• Do not continue driving if the generator belt is loose, broken or missing.

or Electronic parking brake indicator light (if so equipped)

This light illuminates when the electronic parking brake system is operating.

When the ignition switch is placed in the ON position, the electronic parking brake warning light illuminates. When the engine is started and the parking brake is released, the warning light turns off.

If the parking brake is not released, the electronic parking brake warning light remains illuminated. Ensure the electronic parking brake warning light has turned off before driving.

If the electronic parking brake warning light illuminates or flashes while the electronic parking brake system warning light (yellow) illuminates, it may indicate that the electronic parking brake system is not functioning properly. Have the system checked. It is recommended that you visit a NISSAN dealer for this service.

For additional information, see "Parking brake".

This light warns of low engine oil pressure.

If the light flickers or comes on during normal driving, pull off the road in a safe area, stop the engine immediately and call a NISSAN dealer or other authorized repair shop.

The engine oil pressure warning light is not designed to indicate a low oil level.

Use the dipstick to check the oil level. For additional information, see "Engine oil".
