VOLKSWAGEN TOUAREG 2012 Owners Manual

The Autonomous Emergency Braking function should be deactivated by switching off the Forward Collision Warning system (Front Assist) in following situations:
x When the vehicle is being towed.
x When the vehicle is on a roller test stand.
x When the vehicle is off road, like on construction sites or on race tracks.
x When one of the sensors is defect.
x When the sensors have been damaged, like after a frontal collision accident.
x After several false alarms in a row.
x If the sensors are covered by additional parts, like auxiliary headlights.
x If the vehicle is driving on steep terrain or on or across slopes.
WARNING
Always remember that the Autonomous Emergency Braking function has limits – it will not release you from the responsibility to control and slow down your vehicle.
x The Autonomous Emergency Braking function alone cannot avoid accidents and fatal injuries.
x Under certain circumstances and complex traffic situations the Autonomous Emergency Braking function can perform unwanted braking maneuvers, like in construction sites.
x Soiled or misaligned radar sensors can lead to unwanted braking maneuvers
x The Autonomous Emergency Braking function does not react to people, animals, crossing traffic or vehicles that are approaching you on the same lane.
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 follow a vehicle so closely that you cannot stop your vehicle safely, under certain circumstances the automatic braking function cannot bring the vehicle to a stop in time.
x Never allow the closing speed between you and other vehicles to be so high that the Au-tonomous Emergency Braking function 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 Always be prepared to takeover the control of the brake and the gas pedal in every situa-tion.
NOTICE
If you notice that the Autonomous Emergency Braking function doesn't work properly or the sensors are damaged, switch off the Forward Collision Warning system (Front Assist) and therefore the Autonomous Emergency Braking function immediately.
x Go see an authorized Volkswagen dealer or Volkswagen Service Facility for assistance and have the system checked.
If the Autonomous Emergency Braking function initiates a braking maneuver, the hydraulic brak-ing 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.
The Autonomous Emergency Braking function can slow your vehicle down to a standstill, but not hold your vehicle permanently. When necessary, apply the vehicle brakes!

Should the Autonomous Emergency Braking function not work properly as described here and initiate several false alarms unwanted braking maneuvers in a row, temporarily deactivate the Forward Collision Warning system (Front Assist) and therefore the Autonomous Emergency Braking function. Have the system checked by an authorized Volkswagen dealer or Volkswagen Service Facility.
Special driving situations

Fig. 277

Vehicles with oversize loads
Under certain circumstances vehicles carrying oversize loads or loads that exceed the vehicle dimen-sions, like flat-bed trailer trucks, can't be recognized correctly by the ACC. Switch off ACC when driving behind such vehicles.
Other vehicles changing lanes
Vehicles that change into your lane within a short distance can only be detected by the radar sensor
once they are within sensor range ⇒ fig. 278 (C). The result is a delayed reaction by the Adaptive Cruise Control.
Stationary vehicles
If a vehicle detected by Adaptive Cruise Control turns or changes lanes and there is a stationary vehicle in front of that vehicle, the system will not react to the stationary vehicle (D).
Narrow vehicles
Narrow vehicles, such as motorcycles traveling ahead, are often detected late or not at all under some circumstances.
Oncoming vehicles
ACC does not detect oncoming vehicles on your lane.
Metal objects on the road
Metal objects on the road, such as tracks, can cause irritations for the ACC due to falsely reflected radar signals and therefore lead to unwanted reactions of the system, such as abrupt braking maneu-vers.
Radar sensor impaired by rain and dirt
If the radar sensor function is impaired by heavy rain, spray, snow or mud, Adaptive Cruise Control switches off temporarily. ACC not available. No sensor view! appears in the instrument cluster display.
When Adaptive Cruise Control is reactivated after this message is displayed, it functions like a “stand-ard” cruise control system. It maintains the set speed but it does not regulate the distance to the vehicle ahead.
Overheated brakes
Adaptive Cruise Control may switch off temporarily if the brakes overheat significantly, for example from braking maneuvers or driving down steep slopes. ACC not available appears in the instru-ment cluster display. Adaptive Cruise Control cannot be activated.
Adaptive Cruise Control can be activated again once the temperature of the brakes decreases suffi-ciently. The message ACC not available in the instrument cluster switches off.
If the message ACC not available does not switch off, there is a malfunction. Contact your au-thorized Volkswagen dealer.
Trailer towing
When towing a trailer, ACC and the Forward Collision Warning system (Front Assist) may work only with limited functionality.
Text messages in the instrument cluster display

Lane Assist

WARNING
If the view area of the camera is covered or dirty, Lane Assist may not work properly.
x Always make sure that the camera area is free of dirt or snow and not covered.
NOTICE
In order to help maintain the proper function of the Forward Collision Warning system (Front Assist):
x Always keep the camera area in the front windshield free of ice, dirt and snow.
x Never cover the camera area.
x Regularly check the windshield and especially the area of the camera for damages.
Lane Assist has been developed only for on-road driving.
If Lane Assist does not work properly and as described here, have the system checked by an authorized Volkswagen dealer or Volkswagen Service Facility.
Warning and Indicator lights

lights
up Possible cause Proper response
Minimum speed not yet reached.

When the ignition is switched on, several warning and indicator lights come on briefly for a function check. They go out after a few seconds.
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
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
How Lane Assist works

Before starting to drive, always make sure that the area of the camera ⇒ fig. 279 is not covered.
When to deactivate Lane Assist

Lane Assist settings in the infotainment system
You can change some Lane Assist settings in the infotainment system
x Switch on the ignition.
x Push the infotainment button CAR.
x Tap on the Assistants button in the display.
x Select Front LaneAssist.

Function key
Warning time setting : After touching the Warning time setting or z func-
tion key, you can choose between early, medium and late.
Steering wheel vibration : After touching the Steering wheel vibration or z
function key, you can choose between low, medium and strong.

Setting the warning time

Menu option Meaning
Early The system has a low tolerance level and warns
you early if you come too close to a side marking.
Medium Original setting.
Late The system has a high tolerance level and warns
you late if you come too close to a side marking.

The warning time setting defines the distance from your vehicle to the side markings. An early warning time means that the distance to the side markings has to be high in order for Lane Assist not to trigger a warning.
The time of the warning is also dependent on the approach angle to the side marking and the driving speed. If, for example, you approach a road marking at a steeper angle, the steering wheel will start vibrating at a greater distance.
Setting the vibration level of the steering wheel

Menu option Meaning
Low Light vibration of the steering wheel.
