Left Steering Wheel Switch
The left steering wheel switch contains the controls for the IPC menu selection. The left steering wheel switch comprises a central 'MENU/OK' switch and a 4-way switch to allow menu selection 'UP/DOWN/LEFT/RIGHT'. The left steering wheel switch is also used to control the audio system.
The driver can navigate to the required menu using the 'UP/DOWN' and 'LEFT/RIGHT' switches. When the required menu is highlighted it can be selected using the 'MENU/OK' switch.
When the 'MENU/OK' switch is operated to select the menu, the screen displays a sub-menu for that option or activates the selected item. Scroll arrows to the left of the menus show that additional menu items are available that are not visible in the current view. When the arrow is displayed brightly it indicates that additional menu items are available in that direction.
The current displayed menu can be closed by operating the 'LEFT' switch on the menu switch. When sub-menus are open, pressing and holding the 'LEFT' switch on the menu control closes the sub-menus. The menu closes automatically when:
- No selection is made in the main menu within 10 seconds of opening.
- A selection is made in the main menu and no further selection is made within 30 seconds. When a selection is made within the 30 second period, the timer is reset. A further 30 seconds elapses before the menu automatically closes if no selections are made.
