warning VOLKSWAGEN JETTA 2017 Service Manual

person who is not using the safety belt. Leaving the extender attached to the safety belt buckle when the front seat is occupied and the safety belt is not being used will signal the airbag control unit during a collision that the front passenger seat is occupied and that the safety belt is being used. The elec-tronic control unit for the airbag system will then receive incorrect information that will cause the safety belt pretensioner to deploy unnecessarily and the front passenger airbag to deploy later in collisions that would normally trigger the front airbag earlier in the collision to help protect an unrestrained front seat occupant. The airbag will not be able to provide enough protection for an occupant not wearing a safety belt.
x Only use the safety belt extender approved by Volkswagen for your vehicle.
WARNING
Improper use or positioning of a safety belt extender increases the risk of serious personal injury and death.
x A driver or passenger who is not properly restrained can be seriously injured by striking the interior of the passenger compartment or by the safety belt itself, which can be displaced from stronger parts of the body into sensitive areas like the abdomen.
x Safety belt extenders offer optimum protection only when they are properly used.
x Only use the extender when the belt is not long enough to be worn low and snug and the person is in the correct seating position. Remove and stow extender safely when not needed.
x Always make sure the safety belt tongue of the safety belt extender is securely inserted into the buckle for the seating position that belongs to the seat where the safety belt extender is being used. Attaching the safety belt to the wrong buckle will reduce safety belt effective-ness and can cause serious personal injury.
x Never use the safety belt extender if you can properly attach the safety belt without it. Using a safety belt extender when not needed can increase the risk of injury, especially in a collision.
x Never use a safety belt extender if the distance (B) between the front edge of the safety belt extender buckle (A) and the centerline of the person using the safety belt extender
⇒ fig. 64 (C) is less than 6 inches (15 cm).
x Never leave a safety belt extender attached to the vehicle safety belt buckle when the extender is not needed and being used with the safety belt. Otherwise, the airbag control module will receive an incorrect signal from the safety belt buckle and this will prevent the airbag from working properly for a person who is not using the safety belt.
x Never use more than 1 extender with a safety belt. Using more than 1 extender can change the way the safety belt passes over the body and can cause serious injury.
x Never use the safety belt extender to secure a child restraint.
x Never use a safety belt extender on your Volkswagen that you got from another automo-bile manufacturer or from an automotive parts store.
x Never use the safety belt extender you got for your vehicle for any other vehicle, regard-less of make, model, or model year.
NOTICE
x Leaving the extender attached to the safety belt buckle when the front seat is occupied and the safety belt is not being used will signal to the airbag control unit that the front passenger seat is occu-pied and that the safety belt is being used. The electronic control unit for the airbag system will then receive incorrect information that will
– cause the safety belt pretensioner to deploy unnecessarily in collisions.
– cause the front passenger airbag to deploy later in collisions in which the front airbag would otherwise be triggered earlier to help protect an unrestrained front seat passenger.

x A pretensioner that has deployed cannot be repaired. The entire safety belt must be re-placed.
NOTICE
If the safety belt extender is left attached to the safety belt buckle, the safety belt warning system will sense that the safety belt for that seat is being used. The warning light will not come on and the warning chime will not sound even though the seat is occupied and the safety belt is not being used.
Safety belt retractor, pretensioner, load limiter

Undeployed safety belt pretensioners and airbag modules contain explosive materials that can cause serious injuries to the general public and to people who work at dealerships and workshops, scrap yards, and recycling facilities. For this reason, the systems must be properly handled when they or the vehicles they are installed in are scrapped.
Undeployed safety belt pretensioners and airbag modules can also pollute the environment. Never abandon vehicles or vehicle parts. If your vehicle must be scrapped, please make sure that it is done safely, responsibly, and in compliance with all applicable environmental regulations. Take it to a li-censed facility that has the knowledge and experience to properly dispose of the vehicle and its safety belt system. Your authorized Volkswagen dealer and authorized Volkswagen Service Facility are familiar with these regulations.
WARNING
Improper handling, care, servicing, and repair procedures can increase the risk of personal injury and death by preventing a belt pretensioner from activating when needed or by caus-ing it to activate unexpectedly.
x The pretensioner can be activated only once. If a pretensioner has been activated, the safety belt must be replaced.
x Safety belt systems including the pretensioners cannot be repaired. Special procedures are required to remove, install, and dispose of this system.
x Never repair, adjust, or change pretensioners or any other part of the safety belt system yourself. We strongly recommend that you have any work on the safety belt system per-formed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. They
have the necessary technical information, training, and special equipment ⇒  Parts, accesso-ries, repairs, and modifications.

Lights and vision features

Adaptive Front Lighting System (AFS)
The Adaptive Front Lighting System (AFS) works only with the low beams switched on and only at speeds above about 6 mph (10 km/h). The swivel-mounted lamps automatically improve road illumina-tion during cornering.
In some models, the headlights will turn independently, even when driving straight ahead. They can adjust according to the weather conditions and the speed of the vehicle to better light up the road ahead. The bulbs return to their original position after a short period of time, depending on the vehicle speed.
On vehicles equipped with the Adaptive Front Lighting System, the feature is switched on and off via
the Assistants menu in the instrument cluster display ⇒ page 16, Volkswagen Information System.
WARNING
Crashes and other accidents can happen when you cannot see the road ahead and when you cannot be seen by other motorists.
x Never use daytime running lights (DRL) to see where you are going. DRL are not bright enough to light up the roadway and be seen by other motorists.

Interior and reading lights

x Crack or chip in the windshield: If a stone hits and chips the windshield while the rain sensor is on, this will trigger a wiper cycle. After that, the rain sensor will recognize the change and recalibrate itself to respond to the sensitive surface's reduced detection zone. Depending on the size of the chip, the sensor's reaction pattern may or may not change.
WARNING
The rain sensor cannot always recognize rain and activate the wipers.
x Switch the wipers on manually when water on the windshield reduces visibility.
Clean the rain sensor's sensitive surface ⇒ fig. 87 (arrows) regularly and check the wiper blades for wear or damage.
To remove wax and coats of polish safely, we recommend using an alcohol-based windshield cleaner.
