Electric Parking Brake Light

This light comes on when the parking brake is applied. If the light continues to flash after the parking brake is released, or while driving, there is a problem with the electric parking brake system. A message may also appear in the Driver Information Center (DIC).
If the light does not come on, or continues to flash, see your dealer.

This light should come on briefly when the vehicle is started. If it does not, have it repaired so that it will be ready to warn you if there is a problem.
If this light stays on, take the vehicle to your dealer as soon as possible. See Electric Parking Brake under Parking Brake. A message may also appear in the Driver Information Center (DIC).
