Climate comfort retaining function
The climate in the passenger compartment can be maintained when the vehicle isparked, e.g. if the engine is turned off but thedriver or passengers remain in the vehicle.
This function can only be direct-started. The function utilizes several of the vehicle's systems:
Residual heat from the engine is used tohelp heat the passenger compartment to acomfortable temperature.
In warm weather, the ventilation systemcools the passenger compartment byblowing air in from outside.
NOTE
Climate comfort maintenance will be deac- tivated if the vehicle is locked from the out-side in order to avoid using residual engineheat unnecessarily. This function isintended to be used to maintain climatecomfort when the driver or a passengerremains in the vehicle after the engine isturned off.

Starting and stopping the combustion engine in Twin Enginevehicles An advanced control system determines the distance that the vehicle can be driven on thecombustion engine, electric motor, or both atthe same time. When driving on only theelectric motor, the vehicle may automaticallystart the combustion engine due to outsidecircumstances, e.g. low ambient tempera-tures. This is completely normal. The com-bustion engine will also always start whenthe hybrid battery is nearly fully discharged.
Climate settings at low temperaturesAt low ambient temperatures, the combustion engine will sometimes start automatically tohelp achieve the desired passenger compart-ment temperature and air quality. The amountof time the combustion engine is running canbe affected by lowering the temperature
reducing blower speed
activating
Pure drive mode.
Using the electric motor in hot or cold
weather
At very low or high ambient temperatures, the electric motor's driving range and power maybe reduced and affect how often the combus-tion engine automatically starts.
Emission control systemTo help ensure that the emission control sys-tem is as energy-efficient as possible, thecombustion engine will run for several minutesafter it is started. The amount of time the com-bustion engine needs to be used variesdepending on the temperature of the three-way catalytic converter.

Pure
Uses the electric motor only, with the low- est possible energy consumption and car-bon dioxide emissions.
This drive mode prioritizes the use of thehybrid battery. Certain climate system func-tions are reduced to provide the longest dis-tance using only electricity.
Pure mode is available when the hybrid bat-
tery is sufficiently charged. Even in Puremode, the combustion engine will start if the charge level in the battery gets too low. Thecombustion engine will also start
if the vehicle's speed goes above125 km/h (78 mph)
if the driver requests more power than theelectric motor can provide
if factors such as cold weather affect thesystem or components.
This drive mode is adapted for the longestpossible driving distance with electric propul-sion and is primarily intended for use in city driving.
Pure helps provide the lowest possi-
ble consumption even when the hybrid battery is fully discharged. ECO climate is activated tocontrol the climate in the passenger compart-ment, and in slippery road conditions slightlymore wheel spin may be permitted before all-wheel drive is automatically activated.
ECO Climate
In Pure mode, ECO climate is automatically
activated in the passenger compartment to help reduce energy consumption.
NOTE
When the Pure drive mode is activated,
settings for certain climate system and electricity consuming functions arereduced. Some of these settings can bereset manually, but full functionality will only be restored by leaving
Pure mode or
adapting the Individual drive mode to full
climate system functionality.
If condensation forms on the windows, tap the max defroster button, which will function nor-mally.
Constant AWD
Improves the vehicle's traction and han- dling by increasing all-wheel drive.
This drive mode locks the vehicle in all-wheeldrive. An adapted distribution between frontand rear axle torque provides effective control,stability and traction, e.g. on slippery roads orwhen towing a heavy trailer or another vehicle. The
Constant AWD drive mode is always
available regardless of the hybrid battery's charge status. Both the combustion engine and the electricmotor are engaged to enable all-wheel drive,which results in higher fuel consumption. In the other drive modes, the vehicle automati- cally adapts the need for all-wheel driveaccording to the road surface, and can acti-vate the electric motor or start the combustionengine as needed.
Power

The vehicle gets sportier driving characte- ristics and a faster acceleration response.
This drive mode adapts the combined powerfrom the combustion engine and the electricmotor by providing power to both the frontand rear wheels. Gear shifting will be fasterand more distinct and the transmission willprioritize gears with a higher traction force.Steering response is faster and suspension isstiffer. Both the combustion engine and the electric motor are engaged to enable all-wheel drive,which results in higher fuel consumption.

Using the electric or combustion engine
An advanced control system determines the distance that the vehicle can be driven on thecombustion engine, electric motor, or both atthe same time. Its primary function is to use the motor/engine and the current available in the hybrid batteryas efficiently as possible based on the charac-teristics of the various drive modes and thepower output requested by the driver bypressing the accelerator pedal. In certain cases, temporary limitations in the system or mandatory functions to help main- tain a low overall emissions level may result in greater use of the combustion engine.

Economical driving
Drive economically and more environmentally conscious by thinking ahead and avoidingrapid starts and stops.
Adapt your driving style and speed to the cur- rent traffic conditions. To help achieve the greatest distance with the lowest fuel consumption with Twin Engine,observe the following:
Charge
Charge the vehicle regularly by plugging it into an electrical outlet. Make it a habit toalways begin trips with the hybrid batteryfully charged.
Locate charging stations along your route.
If possible, choose parking spots withcharging stations.
NOTE
Charge the vehicle from the electricity grid as often as possible!
Preconditioning
Whenever possible, precondition the vehi- cle before driving by connecting thecharging cable to an electrical outlet.
Avoid parking the vehicle somewherewhere the interior will become too hot ortoo cold while the vehicle is parked. If pos- sible, park the vehicle in a climate-con-trolled garage.
During a short drive after passenger com-partment preconditioning, turn off thepassenger compartment fan or the airconditioning in a hot climate.
If preconditioning is not possible when itis cold outside, use seat and steeringwheel heating first. Avoid heating theentire passenger compartment to reducethe amount of current being taken fromthe hybrid battery.
