Plan for electric operation
It is important to plan carefully when driving in electric mode in order to achieve the longest possible driving distance:
- Charge the car regularly from the mains power circuit. Make it a habit to always start a journey with fully-charged hybrid battery.
- Find out where the charging stations are located.
- If possible, select a parking space with a charging station.
- Precondition the car before driving if possible using the charging cable connected to the mains power circuit.
- Avoid parking the car in a way that the interior cools down or overheats while parking. Park the car in an acclimated garage, for example.
- During a short drive after preconditioning of the passenger compartment, switch off the ventilation fan if possible.
- If preconditioning is not possible when it is cold outside, use seat heating and steering wheel heating first of all*. Avoid warming up the whole of the interior which takes energy from the hybrid battery.
An energy-saving driving style reduces power consumption and makes it possible to extend the range.
- For lowest energy consumption, activate the Pure drive mode.
- Drive at a steady speed and keep a good distance to other vehicles and objects to minimise braking.
- Balance the power requirement using the accelerator pedal. Use the indicator for available electric motor power in the driver display, see Eco guide & Hybrid guide, in order to avoid starting the internal combustion engine unnecessarily. The electric motor is more efficient that the internal combustion engine, in particular at low speed.
- During braking - brake gently with the brake pedal, this recharges the hybrid battery. A regenerative braking function is integrated in the brake pedal.
- When driving in hilly terrain, utilise the engine braking function. The car engine brakes when the accelerator pedal is released and the hybrid battery is recharged.
- High speed results in increased energy consumption - the wind resistance increases with speed.
- Select drive mode Save at higher speeds during drives which are longer than the range of the electricity.
- Drive with the correct air pressure in the tyres and check this regularly - select ECOtyre pressure for best results.
- Choice of tyres can affect fuel consumption - seek advice on suitable tyres from a dealer.
- Remove unnecessary items from the car - the greater the load the higher the consumption.
- A roof load and ski box increase air resistance, leading to higher consumption - remove the load carriers when not in use.
- Avoid driving with open windows.
- Do not hold the car stationary on a hill with the accelerator pedal. Use the foot brake instead.
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.
The electric motor, electronics and batteries work best at approx. 25 °C. When the car is connected to an electrical socket it is conditioned to its optimal temperature range. If the car is started in cold weather or goes beyond its permitted temperature range while driving then the fuel heater starts and, if required, the internal combustion engine starts automatically so that heating takes place. The car can be driven electrically but with reduced power if the temperature becomes too low.
Similarly, the system may need to be cooled down when driving in hot conditions.
If the outside temperature drops extremely low then the diesel engine will always be running.
The more power consumers in the car that are switched on (e.g. stereo, electrically heated windows, door mirrors, seats, etc.) the higher the energy consumption.
