General information about Twin Engine

Twin Engine runs like a regular car, but certain functions differ from a car that only runs on petrol or diesel. The electric motor drives the car mostly at low speeds, the petrol engine at higher speeds, as well as during more active driving.

Important to know

Car without power

Bear in mind that important functions such as the brakes and power steering are inoperable when the car is without power.

 Warning

In a de-energised car with the electric motor and fuel-driven engine switched off it is not possible to brake the car.

Towing not permitted

Towing the Twin Engine is not permitted since this damages the electric motor. When moving the car it must be transported raised up with all the wheels on a recovery vehicle's platform.

Exterior engine noise

 Warning

Remember that the car does not emit any engine noise when it is only powered by the electric motor and may therefore be difficult to notice by children, pedestrians, cyclists and animals. This applies in particular at low speeds, such as in car parks.

High-voltage current

P5-1507-Symbol Elecric warning

Several components in the car work with high-voltage current that could be dangerous in the event of incorrect intervention. Do not touch anything that is not clearly described in the owner's manual, see section "Engine compartment overview" for an overview of the engine compartment's components.

 Warning

Orange-coloured cables must only be handled by qualified personnel.

Unique functions

Drive modes

It is possible to set the car in different drive modes while driving, e.g. electric operation only or, when power is required, both electric motor and petrol engine. The car calculates an optimal combination of driveability, driving experience, environmental impact and fuel economy according to the drive mode selected. Read more in the section "Drive modes".

Driver display

The driver display shows some information that is unique to the Twin Engine - charging information, selected drive mode, distance to empty battery as well as the hybrid battery's charge level. Read more in the sections "Hybrid related information in the driver display" and "Drive modes".

Preconditioning

In order that the car should have optimal function it is important that the hybrid battery with associated electrical drive systems, as well as the petrol engine and its drive systems, have the correct operating temperature. Battery capacity is reduced considerably if the battery is too cold or too hot. Preconditioning prepares the car's drive systems and the passenger compartment before departure so that both wear and energy needs during the journey are reduced. The range for the hybrid battery increases. Read more in the section "Starting/stopping preconditioning".

Charging the hybrid battery

 Important

Never connect the charging cable when there is a risk of lightning.

The hybrid battery is the Lithium-ion type and can be recharged in different ways. A charging cable with control unit can be connected between the car and a 230 VAC socket1. Charging time depends on charging current. Read more in the section "Charging the hybrid battery".

The hybrid battery can also be charged by the car's engine. The hybrid battery is recharged during gentle braking with the brake pedal. The hybrid battery is also recharged during engine braking in gear position B when e.g. travelling downhill. Read more in the sections "Gear positions for automatic gearbox" and "Hybrid related information in the driver display".
