| T-TT-0591-20 | 2020-02-24. Service bulletin. PARKING BRAKE; POWER TRAIN; SEAT BELTS. TT: A message to replace the battery may indicate on the dash. This message can display when the voltage drops too low and is to assure the customer receives the vehicle with a fully charged battery. Due to the high amp draw when the vehicle is not shut down, this vehicle depletes the battery charge much quicker than other Toyota vehicles, so dealers must use care to maintain battery charge on their lot. Care should be made to use the key fob to lock the vehicle upon every exit of the vehicle. If you are going to remain in the vehicle, press and hold the power button on the radio. |
