switched of 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 Tachometer for the combustion engine shows zero engine revolutions.
x Instrument cluster display.
x Infotainment System screen.
Extended electro-mode drive (%

This depends on vehicle conditions of the hybrid drive system is normal and is designed to save fuel. The power steering and the braking assistance systems remain active. In certain situations it may be necessary for the system to start the combustion engine even when the vehicle is not moving. With prolonged driving in traffic jams, the combustion engine will be switched on and off to charge the high-voltage battery for the following start-stop phase.
Sailing
If the accelerator is not depressed and the lever is in Drive (D), the internal 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 vehicles power requirements. Even in this case, the rev counter in the instru-ment cluster displays zero engine speed (0 engine revolutions). 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.
When the high voltage battery is fully charged, there is no brake energy recuperation, and therefore no engine braking. Recuperation and engine braking are also automatically reduced if the vehicle detects that the road conditions do not permit sufficient contact between the wheels and the road surface.
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 High-voltage battery being charged at high rate when decelerating. The high-voltage battery can-not 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 transmis-
sion is in Park (P) or Neutral (N) ⇒  Warning when leaving the vehicle.

An indicator light k comes on in the instrument cluster display whenever Hill Descent Assist is ena-bled. The indicator light blinks when Hill Descent Assist is regulating the brakes.
Hill Descent Assist is always enabled, but only regulates the brakes when certain requirements are met.
Hill Descent Assist regulates automatically:
x If the vehicle is in off-road mode and the indicator light k is on.
x And: If your speed is under 18 mph (30 km/h).
x And: If the downhill grade is 10 % or steeper.
x And: If you neither accelerate nor apply the brakes.
x And: If the vehicle's engine is running.
If you accelerate or step on the brake when Hill Descent Assist is operating, the feature switches off. Hill Descent Assist begins regulating speed again the next time the requirements are met.
Hill Descent Assist does not regulate speed:
x On downhill grades of less than 10 %.
x OR: At speeds over 18 mph (30 km/h).
x OR: If the driver brakes or accelerates.
WARNING
Always be ready to apply the brakes. Otherwise accidents and injuries can occur.
x Hill Descent Assist is merely a driving aid and cannot always slow the vehicle down enough under on downhill grades.
x The vehicle may pick up speed despite the use of Hill Descent Assist.
The Hill Descent Assist also works when you are backing down a hill.

Warning and indicator lights

Fig. 266 In the instrument cluster display: Cruise control status indications.

WARNING
Always remember that the Adaptive Cruise Control has limits – Using Adaptive Cruise Con-trol when it is not possible to drive safely at a constant speed can be dangerous and can lead to an accident and serious personal injury.
x Adaptive Cruise Control will not slow the vehicle down or maintain the set distance when you drive towards an obstacle or something on or near the road that is not moving, such as vehicles stopped in a traffic jam, a stalled or disabled vehicle.
x Always adjust your speed and the distance you keep between you and the vehicles ahead of you to the road, traffic, weather, and visibility conditions.
x Never use Adaptive Cruise Control on steep, winding, or slippery roads (such gravel roads, wet roads, or snowy or icy roads) or on roads with standing water.
x Never use Adaptive Cruise Control when driving in heavy or varying stop-and-go traffic.
x Never use Adaptive Cruise Control when driving off-road or on unpaved roads.
x Always remember that the Adaptive Cruise Control cannot detect a vehicle that is driving towards you in your traffic lane and that it cannot detect narrow vehicles such as motorcy-cles and bicycles.
x Never follow a vehicle so closely that you cannot stop your vehicle safely. The Adaptive Cruise Control cannot slow or brake the vehicle safely when you follow another vehicle too closely. Always remember that the Adaptive Cruise Control has a braking power that is only about 30% of the vehicle's maximum braking ability, under certain circumstances the auto-matic braking function cannot bring the vehicle to a stop in time.
x Always turn off Adaptive Cruise Control when entering turn lanes, exit lanes and construc-tion zones or in similar situations because the vehicle will automatically accelerate to the stored speed when the road ahead is clear.
x To help prevent unintended operation of Adaptive Cruise Control, switch the system off when it is not being used.
x It is dangerous to use the Resume feature when the previously set speed is too high for the existing road, traffic, or weather conditions.
x When traveling downhill, the Adaptive Cruise Control may not be able to maintain a con-stant speed. The vehicle will speed up because of its own weight. Downshift and/or use the foot brake to slow the vehicle.
x Never allow the closing speed between you and other vehicles to be so high that the Adaptive Cruise Control may not be able to slow your vehicle safely. If closing speed is too high, you must apply the brakes yourself to reduce the risk of a rear-end crash.
x If a driver intervention warning appears in the instrument cluster display, immediately takeover the control of the brake and gas pedals and low down the vehicle or bring it to stop when necessary and according to the traffic situation.
x If a Forward Collision Warning system (Front Assist) collision warning appears in the instrument cluster display, immediately takeover the control of the brake and gas pedals and low down the vehicle or bring it to stop when necessary and according to the traffic situation.
x Always be prepared to takeover the control of the brake and the gas pedal in every situa-tion.
NOTICE
If you suspect that ACC and the Forward Collision Warning system (Front Assist) don't work properly or the sensors are damaged, switch off ACC immediately.
x Go see an authorized Volkswagen dealer or Volkswagen Service Facility for assistance and have the ACC system checked.
