WARNING:
- Always end maintenance mode after performing the servicing in maintenance mode. Otherwise, driving the vehicle without ending maintenance mode could result in an accident.
CAUTION:
- Brake fluid will damage painted surfaces. Be careful not to spill any on painted surfaces. In addition, if there is any brake fluid on the wiring harness, the wire insulation may corrode causing a malfunction such as a short circuit. If brake fluid gets on a painted surface or wiring harness, wash and flush it off completely with water immediately.
- Do not empty the brake fluid in the following brake related parts. Otherwise, the electronically controlled brake unit could be damaged.
- Electronically controlled brake unit
- Brake fluid reserve tank
- Rear brake caliper
- A new rear brake caliper has been plugged sealing off the brake fluid. For this reason, remove the plug of the rear brake caliper directly before installing the rear brake caliper to the vehicle. Other than for this, do not remove the plug of the rear brake caliper.
- When disconnecting the brake hose from the rear brake caliper, always plug and seal the rear brake caliper so that brake fluid does not leak.
NOTE:
- Keep the fluid level in the brake fluid reserve tank at 3/4 full or more during the brake fluid replacement.
- Replace the brake fluid from the brake caliper that is the nearest to the master cylinder.
- When switching to maintenance mode, the electronically controlled brake unit and the electric parking brake functions are canceled.
- When switching to maintenance mode, the clearance between the rear disc pad and the rear disc plate widens.
- When the maintenance mode is ended, the electric parking brake motor gear unit operating time is longer than normal due to the automatic adjustment of the electric parking brake.
- Bleed the air inside the brake fluid reserve tank when the fluid inside the brake fluid reserve tank is empty.
