Maintenance of the high-voltage battery
Other than taking the vehicle in for scheduled maintenance to an authorized Volkswagen dealer or an authorized Volkswagen Service Facility that is qualified to do work on hybrid vehicles, there is nothing that the vehicle driver has to do to maintain the high-voltage battery.
The maintenance connection for the high-voltage battery is under the luggage compartment floor under an orange cover. This connection is only for scheduled maintenance, which must be performed only by specially trained service technicians. There is no need to remove the connector at any time
when the vehicle is being used ⇒ 
WARNING
The high-voltage hybrid electrical system is dangerous and can cause burns, other serious personal injuries, electrocution and death.
x Never open, service, repair, or disconnect the high-voltage hybrid battery.
x Never touch or let jewelry or other metal objects contact high-voltage cables or the high-voltage battery and battery poles, especially if the cables, battery, or battery poles have been damaged in a crash or in some other way.
x Always have work on the hybrid electrical system and on systems that could be indirectly affected by it done by qualified, trained technicians, who have the know-how, experience, documentation, and tools to do the work safely.
WARNING
Failure to heed warning lights and instrument cluster text messages can cause the vehicle to break down in traffic and result in a collision and serious personal injury.
x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
NOTICE
x Failure to heed warning lights or text WARNINGS can result in vehicle damage.
x If the 12 Volt vehicle battery is disconnected or dead or has been replaced, there is a possi-bility 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 author-ized 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.

any requirement for engaging Hill Hold is no longer met while the vehicle is stopped, Hill Hold disen-gages, the indicator light in the button goes out, and the brakes are automatically released and will no longer hold the vehicle.

Hill Hold is activated automatically when points 1 to 3 are met at the
same time:
1. Hold the stopped vehicle on an incline with the foot brake or elec-
tronic parking brake.
2. The engine is running “smoothly”.
3. The transmission must be in Drive (D) or Sport Drive (S) and the
foot brake must be depressed to keep the vehicle from moving.
4. To drive off, take your foot off the brake pedal and gently depress
the accelerator within 2 seconds.
Release the brake as you gently depress the accelerator.

Hill Hold is immediately deactivated:
x If any requirement listed in the table above is no longer met (see ⇒ table on page 453).
x If the engine is not running smoothly or the engine malfunctions.
x If the engine stalls or is switched off.
x If the transmission is in Neutral (N).
x If a tire does not have enough road contact (such as when the vehicle is tipped or at an angle).
WARNING
The intelligent technology of Hill Hold cannot overcome the laws of physics. Never let the increased convenience provided by Hill Hold tempt you into taking risks.
x The Hill Hold feature cannot hold the vehicle in all hill start situations (for example, if the surface is icy or slippery).
x Hill Hold can only help keep the vehicle from moving for less than 2 seconds. After that, the brakes will be released and the vehicle can roll down the hill.
Hill Descent Assist

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.

WARNING
Improper use of the Adaptive Cruise Control can cause collisions, other accidents and seri-ous personal injury.
x Always remember that the Adaptive Cruise Control has limits – it 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 disa-bled vehicle.
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 drive at speeds that are too fast for traffic, road and weather conditions.
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, the automatic braking function cannot bring the vehicle to a stop.
x Never use Adaptive Cruise Control when you cannot drive safely at a steady speed, in-cluding on city streets, on winding roads or when road conditions are poor (for example, on ice, gravel, in fog, heavy rain or on wet roads that increase the risk of hydroplaning).
x The radar sensor's vision can be reduced by rain, snow and heavy road spray. These and similar conditions can prevent vehicles up ahead from being accurately detected and in some cases they may not be detected at all. Do not use ACC when the radar sensors cannot accu-rately detect vehicles moving ahead of you in traffic.
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 Never rest your foot on the accelerator pedal, especially when the Adaptive Cruise Control is being used because doing so will override the braking function.
x Always pay attention to traffic, especially when Adaptive Cruise Control is switched on.
x Always maintain a safe speed and distance between your vehicle and other vehicles while considering the traffic situation. This is the duty of the driver. Adaptive Cruise Control is merely an aid to the driver.
x To prevent unintended operation, always switch ACC 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 existing road, traffic or weather conditions.
x Always select a speed and distance to traffic ahead that is safe and appropriate under the prevailing traffic, road, weather and lighting conditions.
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.
NOTICE
When the vehicle is driving at speeds lower than 20 mph (30 km/h) and the 3%4 button is pressed or the lever is moved to 2%35-%, the vehicle will be accelerated to the lowest possible speed that can be set in ACC of 20 mph (30 km/h)
The stored speed is canceled when the ignition or the ACC is switched off.

WARNING
The Forward Collision Warning system (Front Assist) technology cannot overcome the laws of physics and system-related limits. The driver is always responsible for braking in time. If the Forward Collision Warning system issues a warning, immediately apply the brake to slow the vehicle down or avoid the obstacle, depending on the traffic situation.
x Always adjust your speed and driving style to road, traffic, weather, and visibility condi-tions.
x The Forward Collision Warning system cannot prevent accidents and serious injuries on its own.
x The Forward Collision Warning system can issue unnecessary warnings in certain com-plex driving situations, for example, at traffic islands.
x The Forward Collision Warning system can issue unnecessary warnings when its function is impaired, for example, if the radar sensor is dirty or if the position of the radar sensor has been changed.
x The Forward Collision Warning system does not react to people, animals, or vehicles crossing or approaching in the same lane.
x Always be prepared to take full control of the vehicle at all times.
NOTICE
If you notice that the Forward Collision Warning system (Front Assist) doesn't work properly or the sensors are damaged, switch off the Forward Collision Warning system (Front Assist) immediately.
x Go see an authorized Volkswagen dealer or Volkswagen Service Facility for assistance and have the Forward Collision Warning system (Front Assist) checked.
If the Forward Collision Warning system (Front Assist) initiates a braking maneuver, the hydraulic braking system is under pressure. In this case the braking pedal will feel “harder” and the brake pedal travel will be shorter.
Automatic braking maneuvers can be interrupted by depressing the gas pedal or moving the steering wheel.
Deactivate the Forward Collision Warning system if it does not work as described in this chapter, for example, if multiple unwanted warnings occur. Have the system checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Temporarily switch off the Forward Collision Warning system (Front
Assist) in the following situations

x If the radar sensor malfunctions.
x If external force has affected the radar sensor, for example, after a rear-end collision.
x If the radar sensor is covered (even temporarily) by any accessories or other equipment, for exam-ple, auxiliary headlights.
x If the vehicle is being loaded onto a truck, ferry, or train.
WARNING
Failure to switch off the Forward Collision Warning system in the situations mentioned can cause accidents and serious personal injury.
