warning light VOLKSWAGEN JETTA 2018 User Guide

WARNING
Some kinds of cigarette lighters can be lit unintentionally, or crushed causing a fire that can result in serious burns and vehicle damage.
x Always make sure that there are no lighters in the seat tracks or near other moving parts before adjusting the seats.
x Before closing a storage compartment, always make sure that no cigarette lighter can be activated, crushed, or otherwise damaged.
x Never leave a cigarette lighter in a storage compartment, on the instrument panel, or in other places in the vehicle. Heat buildup in the passenger and luggage compartment of a parked vehicle can result in temperatures in the vehicle that are much higher than the outside temperatures, particularly in summer. High temperatures could cause the cigarette lighter to catch fire.

People suffering from a low level of perceived pain or a lowered awareness of pain as from medica-
tion, paralysis, or chronic illness (e.g. diabetes) should NEVER use the seat heating feature ⇒ !
The use of seat heating by persons with these conditions could result in burns to the back, buttocks, and legs that may take a long time to heal and may never heal completely. If you have any of these conditions, you should take regular breaks and get out of the vehicle, particularly on long trips. Consult your doctor for advice regarding your specific condition.
WARNING

Damage to safety belts reduces their overall effectiveness and increases the risk of serious personal injury and death whenever the vehicle is being used.
x Never let safety belts become damaged by being caught in the door or seat hardware.
x Torn or frayed safety belts can tear, and damaged safety belt hardware can break in an accident.
x Inspect belts regularly for damage. If webbing, bindings, buckles, or retractors are dam-aged, have the belts replaced immediately with the correct replacement belts approved by Volkswagen for your vehicle, model, and model year.
x Safety belts that were subject to stress in an accident and stretched must be replaced with a correct, new safety belt, preferably by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Warning light

Fig. 52 Warning light in the instrument cluster.

A warning chime also sounds.
The safety belt warning light i comes on for 6 seconds when the ignition is switched on. A warning chime also sounds for up to 6 seconds if the driver's safety belt is not buckled. The chime stops soon-er if the driver buckles his or her safety belt. The warning light and the chime go out when both driver and front passenger have buckled their safety belts.
If the driver and front seat passenger do not both fasten their safety belts within about 24 seconds after the chime stops and the vehicle is moving at a speed of more than about 15 mph (25 km/h), the chime will again sound for about 6 seconds, then go off for about 24 seconds, then sound again for about another 6 seconds. The same thing happens if one of the safety belts is fastened and then unfastened while the vehicle is moving. The safety belt warning light i also flashes. The warning chime continues to sound at 24 second intervals for up to 2 minutes. No chime sounds at speeds of less than about 5 mph (8 km/h).
If the ignition is switched on, the safety belt warning light i stays on until the driver and front passen-ger have both buckled their safety belts.

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. You will not be able to see far enough ahead for safety, especially at dusk or when it is dark. Always switch on the low-beam headlights at dusk or when it is dark.

Interior and reading lights

The self-dimming feature can be switched on and off with the switch on the inside mirror (2) A or (2) B. When self-dimming is activated, the indicator light (1) is on.
There are two sensors in the interior mirror housing:
x One sensor on the side facing the interior to measure light from the rear of the vehicle ⇒ fig. 89 A
(3) or ⇒ fig. 89 B (3).
x One sensor on the side facing the windshield to measure light from the front of the vehicle ⇒ fig. 89 C (4).
If the ignition is switched on, the mirror automatically darkens depending on the amount of light shining into the vehicle from the rear.
The self-dimming feature is deactivated when you shift the transmission into reverse or switch on the interior lights or the reading light.
Do not attach external navigation devices to the windshield or in the vicinity of the self-dimming inside
mirror ⇒ .
WARNING

x Malfunctions in the self-dimming function can result in the inside mirror being unable to evaluate the exact distance of vehicles in the rear or other objects.
If the light striking the sensor is filtered or blocked (such as by a sunshade), the self-dimming inside mirror will not work properly or may not work at all.
