Braking precautions

The brake system has two separate hydraulic circuits. If one circuit malfunctions, you will still have braking at two wheels.

You may feel a small click and hear a sound when the brake pedal is fully depressed slowly.

This is not a malfunction and indicates that the brake assist mechanism is operating properly.
