VOLKSWAGEN JETTA 2018 Owners Manual

NOTICE
x The radar sensors in the rear bumper can be damaged or become misaligned in low-speed impacts and parking maneuvers. The system can switch itself off or may be impaired as a result.
x Always keep the rear bumper clean and free of snow and ice so that the radar sensors can function properly. Do not cover the radar sensor area.
x The rear bumper may only be painted with vehicle paint that is approved by Volkswagen. Other paints may impair the function of the Blind Spot Monitor or cause it to malfunction.
x Sunlight may reduce the visibility of the indicator light in the outside mirror.
If the system does not function as described in this chapter or if your vehicle was involved in a collision, do not use the Blind Spot Monitor with Rear Traffic Alert. See an authorized Volkswagen dealer or an authorized Volkswagen Service Facility to have the system checked.
Indicator lights

WARNING
Failure to heed warning and indicator lights and instrument cluster text messages can result in a collision and serious personal injury.
x Never ignore warning and indicator lights or text WARNINGS.
x Always heed warning and indicator lights and take action where necessary.
NOTICE
Failure to heed warning and indicator lights or text WARNINGS can result in vehicle damage.
Blind Spot Monitor

mirror A informs you about traffic to the left, and the indicator light in the passenger side outside mirror B informs you about traffic to the right of your vehicle.
Tinting on the side windows or aftermarket tinting films can interfere with the indicator lights in the outside mirrors or cause false readings.
Keep the glass in the outside mirrors clean and free of snow and ice, and do not cover the mirrors with stickers or other objects.
Radar sensors
The radar sensors are behind the rear bumper on the left and right ⇒ fig. 143. They are not visible from outside the vehicle. They monitor an area about 21 yards (20 meters) behind the vehicle as well as the blind spots on the left and right sides of the vehicle. The monitored area next to the vehicle is about one lane wide.
The width of the lane is not detected individually on each road, but is preprogrammed into the system. Because of this, the indicators may be incorrect when driving on narrow roads or driving in the center of two lanes. Likewise, vehicles that are two lanes away from you or stationary objects such as guard rails may also be detected and cause a false warning.
Driving situations

The Blind Spot Monitor only works at speeds above about 9 mph (15 km/h). The green indicator light 9 in the instrument cluster display switches on automatically when the system is active. The system and indicator light switch off automatically when the vehicle speed drops below about 6 mph (10 km/h).
Physical and system limitations
In certain situations, the Blind Spot Monitor may not interpret the traffic situation correctly. These situations may include:
x When driving in tight curves.
x When the width of the lanes differs.
x When there is a rise in the road surface.
x When there are poor weather conditions.
x When certain types of equipment are on the side of the road, such as high or offset guard rails.
Rear Traffic Alert

WARNING
The Blind Spot Monitor with Rear Traffic Alert technology cannot overcome the laws of phys-ics and limits of the system. Careless or unintentional use of the Blind Spot Monitor and Rear Traffic Alert may result in accidents and serious injuries.
x The Rear Traffic Alert is not a substitute for careful and attentive driving.
x Never use the system when visibility is limited or in confusing traffic situations, for exam-ple, on heavily traveled roads or when there are multiple lanes.
x Always watch for people, especially small children, bicycles, animals, and objects, be-cause the Rear Traffic Alert may not always be able to detect them. Rear Traffic Alert cannot detect people, animals, and things that are moving slowly or not at all.
x The Rear Traffic Alert does not always brake the vehicle to a complete stop.
x The harsh automatic braking will be uncomfortable for many people, and if you or your passengers have special conditions or sensitivities, particularly in the neck, you may want to switch off Rear Traffic Alert.
Using the Blind Spot Monitor with Rear Traffic Alert

Forward Collision Warning (Front Assist)

WARNING
The Forward Collision Warning system 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.
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.

should only be carried out by a qualified workshop ⇒  Parts, accessories, repairs, and modifications. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility for assis-tance.
Incorrectly performed repairs to the front end of the vehicle can change the position of the radar sen-sor and therefore impair the function of the Forward Collision Warning system. Repair work should only be carried out by a qualified workshop. Contact an authorized Volkswagen dealer or an author-ized Volkswagen Service Facility for assistance.
NOTICE
Switch off the Forward Collision Warning system if you suspect that the radar sensor has been damaged or if its position has been changed. This can help prevent further damage. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility to have the radar sensor realigned.
x The radar sensor can become misaligned if it is hit, for example, when parking the vehicle. Readjusting the sensor could impair the performance of the system or cause it to switch off.
x Repairs to the radar sensor require special knowledge and tools. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility for assistance.
x Remove snow with a brush, and remove ice with a solvent-free deicer spray.
