S90 Twin Engine Ignition modes | Volvo Support EN-CA

To enable the use of a limited number of functions when the engine is not running, the ignition can be put in one of three different levels: 0, I and II. These levels are referred to as "ignition modes" in the Owner's Manual.

The following table shows which functions are available in each ignition mode:

Mode	Functions
0	The odometer, clock and temperature gauge are illuminated1. The power seats* can be adjusted. The power windows can be used. The center display is activated and can be used1. The 12 V outlet in the trunk* can be used. The infotainment system can be used1. In this ignition mode, the functions are available for a limited time and then switch off automatically.
I	The panoramic roof, power windows, 12 V outlet in passenger compartment, Bluetooth, navigation, phone, blower and windshield wipers can be used. The power seats can be adjusted. The 12 V outlet in the cargo compartment can be used. Electrical current will be taken from the battery in this ignition mode.
II	The headlights illuminate. Warning/indicator lights illuminate for 5 seconds. A number of other systems are activated. However, seat and rear window heating can only be activated when the engine is running. This ignition mode uses a lot of current from the battery and should be avoided whenever possible!
