Drive modes

Updated 7/23/2018

Selection of drive mode affects the car's driving characteristics in order to enhance the driving experience and facilitate driving in special situations.

Using the drive modes it is possible to quickly have access to the car's numerous functions and settings for different driving needs. The following systems are adapted to obtain the best possible driving characteristics in each respective drive mode:

  • Steering
  • Engine/gearbox/all-wheel drive
  • Brakes
  • Air suspension and shock absorption
  • Driver display
  • Climate settings

Select the drive mode that best suits the current driving conditions. Remember that not all drive modes can be selected in all situations.

Selecting drive mode

P5-1507-drive mode scroll wheel

Press the drive mode control DRIVE MODE.

A pop-up menu is opened in the centre display.

Roll the wheel upward or downward until the desired drive mode is highlighted.

Press the drive mode control or tap directly on the touch screen to confirm the selection.

The selected drive mode is indicated in the driver display.

A message is shown when a drive mode is unselectable, for example:

  • Cannot be selected because gear is in manual
  • Cannot be selected due to low battery
  • Cannot be selected due to low temperature
  • Cannot be selected due to limitations
  • Cannot be selected because speed is too high.

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.

Warning

Do not leave the car in an unventilated area with activated drive mode and the fuel-driven engine switched off - automatic engine start occurs at low energy level in the hybrid battery, and the exhaust gases could then cause serious injury to people and animals.

HYBRID

  • This is the car's normal mode where the electric motor and internal combustion engine work together.

When the car starts, it is in the Hybrid mode. The control system uses both the electric motor and internal combustion engine - individually or in parallel - and calculates optimal use with regard to performance, fuel consumption and comfort. At higher speeds the ground clearance is adjusted automatically to a lower level in order to reduce wind resistance. The capacity to run solely with the electric motor depends on the hybrid battery's energy level and, for example, the need for heating/cooling in the passenger compartment.

If high power output is available, it is possible to drive with electrical power alone. When the accelerator pedal is depressed, only the electric motor is activated until a certain position is reached. The internal combustion engine starts when this position is exceeded and the energy level in the battery is insufficient for the engine power that the driver requests with the accelerator pedal.

At low energy level (hybrid battery almost empty) the battery's energy level must be maintained, leading to the internal combustion engine starting more often. Charge the hybrid battery from a 230 VAC socket with the charging cable, or activate Charge in the function view in order to restore the capacity to drive on electric power alone, see the section "Maintain or increase the hybrid battery's state of charge while driving".

Information in the driver display

When driving in the Hybrid mode the driver display shows a hybrid gauge. The pointer in the hybrid gauge indicates how much energy the driver requests with the accelerator pedal. The marking between the lightning bolt and the drop shows how much energy is available. Read more about the hybrid symbols in the section "Hybrid related information in the driver display".

The driver display also shows when energy is returned to the battery (regenerated) during light braking. More information on regeneration is available in the section "Foot brake".

PURE

  • Drive the car with electric motor, with energy consumption as low as possible and with lowest possible carbon dioxide emissions.

The drive mode maximises driving on the hybrid battery. This means, for example, that the ground clearance is lower to reduce wind resistance and the output of certain climate settings is reduced to provide the longest possible mileage on electric power alone.

The Pure mode is available when the hybrid battery has a sufficiently high energy level. The internal combustion engine also starts in the Pure mode if the energy level in the battery falls too low. The internal combustion engine also starts

  • if the speed exceeds 125 km/h(78 mph)
  • if the driver requests more motive force than electric drive can provide
  • in the event of system/component limitations, e.g. low outside temperature.

ECO climate control

In the Pure drive mode, ECO climate control is activated automatically in the passenger compartment in order to reduce energy consumption.

Note

When the Pure drive mode is activated, several parameters in the climate control system's settings are changed, and several electricity consumer functions are reduced. Certain settings can be reset manually, but full functionality is only regained by leaving Pure drive mode or adapting Individual drive mode with full climate functionality.

In the event of difficulties due to misting, press the button for max. defroster which has normal functionality.

OFF ROAD

  • Maximise the car's traction when driving in difficult terrain and on poor roads.

The drive mode provides high ground clearance, steering is light, all-wheel drive and the function for low speed control with hill descent control (Hill Descent Control) are activated.

The drive mode can only be activated at low speeds and the speedometer shows the range for speed limitation. If this speed is exceeded, Off Road mode is cancelled and the AWD drive mode is activated instead.

To be able to drive all four wheels, the internal combustion engine and electric motor run continually, which results in increased fuel consumption.

In the Off Road mode the driver display has a compass between the speedometer and tachometer.

Note

The driving mode is not designed to be used on public roads.

Note

If the car is switched off in OFF ROAD mode, and therefore has high ground clearance, the car is lowered next time it is started.

Important

The OFF ROAD drive mode must not be used while driving with a trailer without trailer connector. Otherwise, there is a risk of damage to the air bellows.

AWD

  • Improve the car's roadholding and traction with enhanced all-wheel drive.

The drive mode is intended for optimum all-wheel drive functionality for slippery driving conditions and increased traction. It also has a stabilising effect when driving at high speed, e.g. when driving with a heavy trailer or during towing.

Both the internal combustion engine and electric motor are engaged in order to drive all four wheels, which results in increased fuel consumption.

In the car's other drive modes, the car automatically adapts the need for all-wheel drive to the road surface, and can engage the electric motor or start the internal combustion engine when necessary.

POWER

  • Power mode means that the car has sportier characteristics and faster response to accelerating.

The drive mode maximises the combined power from the internal combustion engine and electric motor by means of the car being driven by both front and rear wheels. The gear changes become faster and more distinct, and the gearbox prioritises a gear with greater traction. Steering response is faster, shock absorption is harder and a lower ground clearance means that the body follows the roadway in order to reduce roll during cornering.

Both the internal combustion engine and electric motor are engaged in order to drive all four wheels, which results in increased fuel consumption.

INDIVIDUAL

  • Adapting a drive mode according to individual preferences.

Select a drive mode to start from, and then adjust the settings according to the desired driving characteristics. These settings are saved in an individual driver profile.

An individual drive mode is only available if it is first activated in the centre display.

Press Settings in the top view.

Press My CarIndividual Drive Mode and select Individual Drive Mode.

In Preset, select a drive mode to start from: Pure, Hybrid or Power.

Possible adjustments apply to settings for:

  • Driver Display
  • Steering force
  • Powertrain Characteristics
  • Brake Characteristics
  • Suspension Control
  • ECO Climate.

Starting and stopping the combustion engine

An advanced control system determines the extent to which the car is driven on internal combustion engine, electric motor or both in parallel.

The primary function is to use the engine or motor and the available energy in the hybrid battery as efficiently as possible, with regard to the characteristics of the different drive modes as well as the driver's request for power via the accelerator pedal.

There are also cases where temporary limitations in the system, or functions governed by legal requirements aimed at maintaining a low level of total emissions for the car, may use the internal combustion engine to a greater extent.
