Acc VOLKSWAGEN TOUAREG 2017 Owner´s Manual

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.

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.

Adaptive Cruise Control (ACC) with Front Assist

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.

x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
Radar sensors, ultrasonic sensors and Front Assist camera

Fig. 271 Vehicle front view: Sensors and camera

There are 2 radar sensors next to the fog lights on the vehicle front (3). These can detect moving vehicles up to 590 ft (180 m) in front of your vehicle.
The areas of the sensors (2) and (3) and the camera (1) must not be spray painted on or covered by stickers or other objects, since this can lead to a malfunction of the Adaptive Cruise Control (ACC) and the Front Assist system.
NOTICE
If you notice that Adaptive Cruise Control (ACC) or Front Assist doesn'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.
x The sensors can be damaged or become misaligned in low speed impacts and parking maneuvers. Damaged or misaligned sensors can cause ACC or Front Assist to malfunction.
x To help make sure that the system works properly, always keep the sensors clean, free of snow and ice; do not cover the sensors with stickers or other objects.
x When cleaning the sensors with power washers or steam cleaners, only spray the sensors directly for a very short time, and always keep the washer nozzle at least 4 inches (10 cm) from the sensors.
x For Declaration of Compliance to United States FCC and Industry Canada regulations
Always keep the area of the Front Assist camera clear of ice and snow.
Switching ACC on and off

Fig. 272 On the steering wheel column: Lever for Adaptive Cruise Control.

Fig. 273 Lever for Adaptive Cruise Control: Setting the distance (time intervals)

By depressing the gas pedal while the vehicle is standing still and ACC is active, the vehicle will ac-celerate. Once you take your foot off the pedal, ACC will automatically resume the stored speed and regulate the set distance.
ACC will not automatically accelerate if the vehicle ahead accelerates.
Distance (time interval) to the vehicle ahead and driving profiles
The distance the ACC maintains to the vehicle traveling ahead is determined by time intervals. A time distance to the vehicle traveling ahead is maintained. This results in a speed-dependent distance. The
higher the speed, the larger the distance in feet/meters ⇒ .
The distance can be set at 4 different levels:

Distance Time distance at 65 mph
(105 km/h)
Very small about 1,0 Seconds
Small about 1,3 Seconds
Medium about 1,8 Seconds
Large about 2,5 Seconds

Besides changing the time distance, the acceleration characteristics can be changed, by choosing on of the following driving profiles:
x Comfort
x Normal
x Sport
The distance intervals can be set by pushing the slider switch on the lever ⇒ fig. 273. The driving profile can only be set in the infotainment system .
Always select a greater following distance to the vehicle ahead on wet roads than on dry roads.
Setting the distance and selecting a driving profile
In order to show the currently selected distance in the instrument cluster display, briefly tap the sliding
switch on the lever ⇒ fig. 273.

DANGER
Following other vehicles too closely increases the risk of collisions and serious personal injury or even death.
x Always obey applicable traffic laws when setting the distance to the vehicles ahead in traffic.
x Setting short distances to the traffic ahead reduces the time and distance available to bring your vehicle to a safe stop and makes it even more necessary to pay close attention or traffic.
x Always use good judgment and select a safe following distance for the traffic, road and weather conditions.
x Never use Adaptive Cruise Control on narrow or winding roads or under poor road condi-tions (snow, ice, streets covered with standing water or gravel, for example) or when visibility is poor, especially when it is foggy.
x Always select a greater following distance to the vehicle ahead on wet roads than on dry roads.
