In order to increase the car-theft protection of the e-up!, it is equipped with a combined immobilizer. The Immobiliser control unit J362, which is integrated in the control unit for the dash panel insert J285, provides the master. It can operate immobilizer slaves of immobilizer generations IVc and V; it works according to the principle of Immobilizer IVc. The engine control unit J623 is an immobilizer V slave in this case. Electric drive control unit J841 is also an immobilizer IVc slave.

The headlight of the e-up! does not differ from that of the up! in terms of hardware. The difference can be found in the way the lamps in the headlight are activated. The lamp for the daylight running light in the headlight is not activated in the e-up!; only the lamp for the side light (5 W). Two curved LED lights are installed in the bumper; they have three LED lamps, each with three watts. The LED daylight running light is switched off when terminal 58 is activated.

6

The rear lights of the e-up! doe not differ from those of the up!. The highmounted brake light is white and features 16 red LEDs. The lamp in the tail light is identical to that in the tail light and rear fog light, where only the 4 W lamp is activated.

7

The dash panel insert of the e-up! is based on the highline dash panel insert of the VW Beetle. For the e-up!, the display instruments and the multifunction display (MFI) have been subjected to electric drive-specific modifications. Next to the centrally arranged speed display, the battery charge level and the percentage performance indication (power meter) are displayed in an analogue display. The modified MFI can display the following additional information: - electric range - current electricity consumption - average electricity consumption - Information on the charge process - driving mode selection - readiness to drive with display "READY" - ePerformance (currently available electric power)

The maps and more portable navigation and infotainment system J982 is produced by Garmin, and has been since week 22/13. Visually and in terms of function, it is similar to the familiar maps and more made by Navigon, but new functions have been added. The reset button familiar from the Navigon device on the underside of the device has been omitted. A hard reset on a Garmin device is performed as follows: Switch off the device, press one finger on the display while the device is switched off, keep finger pressed on the display and activate the device; wait until the displayed time has elapsed; the device then performs the reset.

Maps and more features live services that provide, for example, information on the current weather, traffic jams and speed cameras, and a local search for points of interest or businesses, for example, with the assistance of an internet connection. For this purpose, it is necessary to connect a data-capable mobile telephone with Bluetooth tethering support to maps and more. A help function for this connection process is displayed when the live services are called. The sources for the live services are the "yelp.com" search engine, the Navteq traffic information and speed camera service, and Garmin's own weather forecast.

The term tethering refers to the action of connecting a smartphone to a computer or PDA in order to enable it to access the internet via GSM/UMTS.

12

The Think Blue Trainer in maps and more has been expanded to include the fuel-saving tips and analysis functions. The "fuel-saving tips" / "energy-saving tips" sub-menu uses charts to give the driver hints on how to drive his up! in a more fuel-saving (energy-saving) and therefore more environmentally friendly way. The "status" sub-menu displays the level of fuel efficiency with fictitious flyballs and the blue circle. The motto: the more blue you see, the better and more efficient. The driver receives blue score points for thrifty driving. In the "analysis" sub-menu, the driving style can be analysed by means of the blue score points or the average fuel consumption over time.

13

The maps and more system in the e-up! and the Eco-up! features multi-stop route planning. That means that the current electrical (CNG) range is considered when the route is planned. Charging options (CNG fuel stations) contained in the POI data are integrated; otherwise, approximate locations are specified, and the vehicle must be charged (fuelled) in the vicinity of these locations. The charging duration during charge stops is included in the overall journey time and also displayed separately.

14

The maps and more system in the e-up! features a new range display. It is possible to display the simple electrical range, the range with consideration of the return journey, and a combination of both in a kind of fried egg display on the map.

Apart from the electrical air conditioner compressor, the refrigerant circuit of the e-up! is identical to the refrigerant circuit of the up! with combustion engine. A single-zone Climatronic is installed 100% in all markets. There are no different variants or country codes. New components in the e-up! are: • Heater and air conditioning unit • Electric air-conditioner compressor • High-voltage heater element • Operating and control unit • Fresh air blower - activation via LIN bus The stationary air conditioning function is also new. It can be activated via a smartphone app or via Maps+More.

The electric air conditioner compressor is installed at the front, right of the electric drive motor. It is designed as a scroll compressor and R134a is intended as the refrigerant. The electric air conditioner compressor would have to be completely overhauled for the e-up!. The challenge is to reduce the effects of the rotating masses in the compressor, both acoustically as well as vibration-specifically. In the case of a combustion engine, they are masked by the engine. In the case of an electric vehicle, they are not masked by the working noise of the engine. Measures are necessary, such as fine balancing and mass reduction of the rotating components . Caution: the electric air conditioner compressor is a high-voltage component. It may only be installed once the high-voltage system has been de-energised and the refrigerant circuit drained. Special qualifications are required to perform work!

19

The high-voltage heater element is necessary because no combustion engine which supplies waste heat is available. The heater element heats up the coolant mixture in the coolant circuit. It is activated by the Climatronic J255 control unit via a LIN data bus. The input and output temperature of the coolant are both measured by a temperature sensor. The high-voltage heater element sends the status data in a LIN message as feedback to the control unit for the Climatronic J255. Technical data: Power:

The high-voltage heater element, the heat exchanger for heater and the coolant pump for the high-temperature circuit are integrated in the high-temperature circuit. The supply is via the connection to the coolant circuit of the engine. The return is via a 2/2 way valve and a non-return valve with 1.5 mm restrictor back to the coolant expansion tank. The coolant pump for the high-temperature circuit is controlled upon request of the air conditioning control unit according to the demand. Activation takes place between 0 and 100%. HHE

The stationary air conditioning can be activated as immediate air conditioning via the smartphone app. The maximum running period is 30 minutes in charging mode and 10 minutes in battery mode. It is not possible to operate the air conditioning system during stationary air conditioning. No controls light up and the buttons are not active. The nominal temperature, the cooling or heating function as well as the red or blue vehicle discs are displayed in the smartphone app in the event of control via CarNet.

22

Stationary air conditioning can be activated by means of timer programming via Maps+More. The request from the charge manager is controlled by the control unit for Climatronic. The nominal temperature and departure time are sent by the charge manager as temperature control request in the control unit for the Climatronic. Furthermore, the provision of the energy required for air conditioning for the high-voltage heater element or air conditioner compressor is released by the charge manager to the control unit for the Climatronic. The maximum power consumption for stationary air conditioning is limited by the charge manager to 3.3 kW. Stationary air conditioning is independent of the selected driving mode. It is not possible to operate the air conditioning system during stationary air conditioning. No controls light up and the buttons are not active. If stationary air conditioning was activated via Maps+More, any other timer entries which may still be stored are ignored. Any changes made here via Maps+More are not synchronised with the smart phone. Stationary air conditioning is deactivated when the readiness to drive is established. The air conditioning system can only be operated by mean of the air conditioner operating unit. Operation in low or high mode is not possible for reasons of energy efficiency.

23

The air conditioning system has a target time logic which automatically calculates the air conditioning duration. The control unit for the Climatronic is woken by the charge manager one hour before the desired departure time in order to calculate the required air conditioning duration and report it back to the charge manager. The air conditioning control unit then returns to sleeping mode. At the calculated starting time, the charge manager wakes the air conditioning control unit and stationary air conditioning begins. The lead time takes up to max. 30 minutes, the lag time is always 15 minutes. No stationary air conditioning takes place if the charge level of the battery is below 20%. Only once the charge level of the battery exceeds 20% can the customer start stationary air conditioning. In this case, it is indicated to the customer that charging with simultaneous stationary air conditioning is restricted. Starting the air conditioning system must be confirmed by the customer. Only charging or air conditioning can take place when charging with alternate current (AC charging). Air conditioning can only take place during the charging process when charging with direct current (DC charging). (The charging station is switched off as soon as the high-voltage battery is charged.)

24

In battery mode, stationary air conditioning starts 10 minutes before the programmed departure time. No stationary air conditioning takes place if the minimum charging capacity of the battery is fallen short of. The minimum charging capacity can be adjusted by the customer.

25

The button for E735 driving modes can be found in the centre console in front of the shift lever.

26

The windscreen heating is implemented as a full-surface windscreen heating with heating wires installed in the shape of a trapezium. This ensures that the entire surface can be kept free from condensation and ice. The windscreen heating is activated with the switch for windscreen heating E… , which is connected to the onboard supply control unit. The heating duration is time-limited. Deactivation takes place by the J519 onboard supply control unit after max. 4 minutes. If necessary, it can be switched on immediately with the button for windscreen heating E…. The windscreen heating can also be switched off by measures taken by the charge management!

27

The windscreen heating can also be activated by the control unit for the Climatronic J255 if the due point* exceeds a defined value. The temperature and humidity on the windscreen are registered and the windscreen heating activated if necessary by the humidity sender for the G260 air conditioning system. In "AUTO" mode, the windscreen heating is automatically activated by the Climatronic in different driving and operating situations. This may make more sense energetically than activating the high-voltage air conditioner compressor of the air conditioning system. This function can be interrupted at any time by pressing the button for the windscreen heating. * Dew point = temperature at which the humidity condenses
