2015 VOLKSWAGEN TOUAREG warning

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.
Forward Collision Warning system (Front Assist) system limits

Autonomous Emergency Braking

Fig. 276 In the instrument cluster display. Warning: Distance to vehicle ahead becoming too small.

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.
