INSTRUMENTS AND CONTROLS DIM PUSH BUTTON (12) - This push button confirms and acquires the anti-theft code. The 4 digits of the secret code must be entered in sequence and each selection must be confirmed by means of the push button 12 (DIM). 15 This button is used also to adjust the luminous intensity of the display (15) and of the leds (day/night) and this can be done after the engine start, the self-test and the display of the 2 nd + - gear. 12 RWA12460 77 • This button engages the 4WD in 1st and 2nd gear with the green led (8) on. If the 4WD is engaged in 3rd or 4th gear, the led flashes and the function is inhibited.

If you shift down from 3rd to 2nd gear with the button (7) on, the logic automatically recalls the 4WD function and the green led stops flashing and lights up continuously. 8 +- 7 RWA12470 8 +- 7 RWA12470 IMPORTANT • In case of braking in 3rd or 4th gear, the logic automatical- ly engages the 4WD and the green led (8) lights up without flashing. 3 2 FWD • After the engine start, the self-test and the entry and confirma- tion of the antitheft code, if any, the electronic control system always sets to the 2nd gear with semiautomatic logic (SA).
