switched off in this mode. Gentle start-ups (getting the vehicle going) and parking are also phases the
electrical motor can often handle alone.
The combustion engine is started if you accelerate faster or if the charge level of the high-voltage
battery gets too low. As soon as allowed by your acceleration and the high-voltage battery charge
level, the vehicle switches back to electrical motor drive.
Use the following indicators to tell when the vehicle is being powered electrically:
x Instrument cluster display.
x Infotainment System screen.
Extended electro-mode drive (EÊMODE)
By pressing the %

Sailing
If the accelerator is not depressed and the lever is in position D, the combustion engine is switched off,
even at higher speeds. The vehicle then decelerates slower than conventional vehicles. This feature
can be used to help reduce fuel consumption when you keep traffic conditions in mind and can
anticipate the vehicle's power requirements. The instrument cluster powermeter shows zero.
Brake energy regeneration (Recuperation/charge)
When the vehicle brakes, the electrical energy is generated by the electric motor, which works as an
alternator and charges the high-voltage battery. The same thing occurs while the vehicle is coasting to
a stop or driving downhill.
Energy regeneration is shown in the instrument cluster display or on the Infotainment System screen.
The combustion engine may be switched off automatically in this situation. The instrument cluster
powermeter registers below zero.
Automatic starting - combustion engine
The combustion engine is started automatically in a number of situations.
x Engine temperature is too low.
x Catalytic converter temperature is too low.
x The high-voltage battery requires recharging.
x High-voltage battery is being charged at high rate when decelerating. The high-voltage battery
cannot absorb any more energy and for this reason the electric motor cannot brake the vehicle. The
combustion engine comes on to help slow the vehicle down (engine brake).
x Engine hood is open.
x Leaving the vehicle when the electric motor is still “live”. The status of the electric motor is not
always obvious, particularly when the combustion engine is not running. The combustion engine will
therefore start if the driver's safety belt is unlatched or the driver's door is opened when the
transmission is in Park (P) or Neutral (N) .

High-voltage battery

NOTICE
x Failure to heed warning lights or text WARNINGS can result in vehicle damage.
x If the 12 Volt battery is disconnected or dead or has been replaced, there is a possibility that
the combustion engine will not automatically switch off when the vehicle is powered by the
electric motor. If this situation persists for several days, take the vehicle to an authorized
Volkswagen dealer or an authorized Volkswagen Service Facility that is qualified to do work on
hybrid vehicles.
x Never transport water or other liquids or fluids in open containers, such as an aquarium. If
liquid is spilled in the luggage compartment, this can cause short circuits or damage the high-
voltage battery.
NOTICE
Never block or cover the cooling air vents for the high-voltage hybrid battery under the rear
seat. Blocking or covering these vents can damage the high-voltage battery.
NOTICE
If the vehicle is not used for a longer period, the high-voltage battery will run down. To keep
the high-voltage battery in good condition, the vehicle needs to be driven at least every 2
months for at least 30 minutes or 15 miles (20 km).
x If the high-voltage battery is dead, the gasoline engine will not start. Contact an authorized
Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop
for assistance.
Special considerations for hybrid vehicles

voltage hybrid components (B).

Jump-starting
If the 12 Volt electrical system is not working because the 12 Volt vehicle battery is dead, the hybrid
vehicle can be jump-started like a conventional vehicle . For this purpose, the vehicle has a jump
start terminal in the engine compartment. You must open the fuse box cover in the engine
compartment to get to the jump-start terminal .
Hybrid warning labels
There are additional warning labels that warn against touching hybrid system components. The
warning labels are placed:
x On each high-voltage component, for example, in the engine compartment or underneath the
luggage compartment ⇒ fig. 116 A.
x In the engine compartment on the hood latch carrier B.
