Ignition modes
The vehicle's ignition can be put in various modes (levels) to make different functions availa-ble.
The vehicle's ignition has 3 modes: 0, I, and II
that can be used to operate various functions without starting the engine. The following tableshows examples of which functions are availablein the respective modes.
Mode Functions available
0 •The odometer, clock and tem- perature gauge are illuminated
• Power seats
* can be adjusted
• The power windows can be oper-ated
• The 12-volt socket in the cargocompartment can be used
• The center display is activatedand can be used
• The infotainment system can beused for a limited time
In this mode, certain functions canonly be used for a limited time to helpminimize battery drain
I •The laminated panoramic roof
*,
power seats */windows,12-volt
sockets in the passenger com-partment, Bluetooth, navigation system *, climate system blower,
windshield wipers can be oper- ated
• The infotainment system will start(if it was started when the ignitionwas switched off)
Using electrical current will drainthe start battery in this mode.Mode Functions available
II •The headlights illuminate
• Warning/indicator lights illumi- nate for 5 seconds
• A number of other functions willalso be activated. However, the heated seats

Battery drain Your vehicle's electrical functions drain the bat- tery to varying extents.
Avoid using ignition mode
II as much as posssi-
ble, or electrical functions that require a great deal of electrical current when the engine is notrunning. Using ignition mode I whenever possible con-
sumes less electrical current. Functions that require a great deal of electrical current include:
• the climate system blower
• headlights
• wipers
• infotainment system (especially at high vol-ume).
If the battery's charge level is low, a text messagewill appear in the instrument panel. The vehicle'senergy-saving function will then turn off orreduce certain functions that are currently con-suming electrical current. If the battery needs to be recharged, start the engine and let it idle for at least 15 minutes ordrive the vehicle (driving charges the batteryfaster than letting the engine idle).

Driving systems
Twin Engine Plug-in Hybrid vehicles are parallel hybrids, which means that they have two sepa-rate drive systems: an electric motor and a gaso-line engine.
Two drive systemsDepending on the drive mode selected and the amount of electric power available in the hybridbattery, the two systems can be used in tandemor separately. The electric motor is powered by a hybrid battery located under the tunnel console. This batterycan be charged from a wall socket or specialcharging stations. The gasoline engine can alsocharge the hybrid battery using a special high-voltage generator. The gasoline engine and electric motor both gen- erate power directly to the wheels. A control sys-tem coordinates both of the drive systems to helpoptimize driving economy.
