Lexus NX: Precaution

PRECAUTION

CAUTION:

  • While the auxiliary battery is connected, even if the power switch is off, the brake control system activates when the brake pedal is depressed or the door courtesy switch is turned on. Therefore, during servicing of the brake system components, do not depress the brake pedal or open/close the doors while the auxiliary battery is connected.
  • The Techstream must be used when bleeding air. If not used, the air bleeding will be incomplete, which is hazardous and may lead to an accident.

NOTICE:

  • Care must be taken to replace each part properly as it could affect the performance of the brake system and result in a driving hazard. Replace parts with those having the same part number or equivalent parts.
  • It is very important to keep parts and the area clean when repairing the brake system.
  • If the vehicle is equipped with a mobile communication system, refer to Precaution in the introduction section.
