2. The system is switched on by pressing the button, as shown in the figure, and can be done "on the go".

When the ignition is turned on (when the ignition key is turned to the "ON" position), the "TRC" indicator lights up for a few seconds. If the indicator does not light up when the ignition key is turned to the "ON" position, or if the indicator lights up continuously while driving, then the "TRC" system may be faulty.

The system is switched off when the "TRC OF" indicator on the instrument panel is constantly lit while driving.

3. When stuck in snow or mud, it may be necessary to turn the system off or on, since TRC can either help or hinder depending on the situation.
