warning light VOLKSWAGEN JETTA 2017 Repair Manual

Make sure there is enough distance to soft materials such as rubber hoses or insulating material.
Never use concentrated jet nozzles or so-called dirt blasters ⇒ .
Never use a power washer to clean the engine compartment ⇒  Cleaning the engine compartment.
WARNING
Improper use of power washers can cause serious invisible permanent damage leading to tire failure and loss of vehicle control. This can cause accidents and severe personal injury.
x Keep sufficient distance between water jet and tires. Never wash tires with a nozzle that sprays the water out in a direct stream regardless of the distance to the tire and even for a very short time.
x Never use “dirt blasters” to clean tires. Even spraying from a relatively long distance for a very short time can do visible or invisible damage to tires.
WARNING
After the vehicle has been washed, the wet brakes or, in winter, brake discs or pads coated with ice, react slower and need longer stopping distances.
x Always dry the brakes and clean off any ice coatings with a few careful applications of the brake. Make sure not to endanger other motorists or cyclists or disobey legal requirements.
NOTICE
x Water temperature should not be more than +140 °F (+60 °C).
x To help prevent damage to the paint, do not wash the vehicle in direct sunlight.
x Do not clean icy or snow-covered windows with a power washer.
x When washing or rinsing the vehicle in cold weather, do not let water get into the lock cylinders or point the hose at gaps around the doors, hood, or luggage compartment lid. The water could freeze on the locks and seals and make it difficult to open the vehicle!

Treating stains
When treating stains, it may be necessary to clean the entire surface and not just the stain itself. This is especially true if the entire surface has become dirty from normal use. Otherwise, the area that is treated may become lighter than the untreated area. If you have questions or concerns, consult a professional cleaner.

Always obey traffic laws that govern the use of emergency flashers where you are driving.
If the emergency flashers are not working, a different method – as permitted by law – must be used to alert other motorists and cyclists to the breakdown.
WARNING
Disregarding the safety-related checklist may lead to accidents and serious personal injuries.
x Always review and follow the checklist. Follow accepted safety practices and use common sense.
WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot. They can cause fires and serious personal injury.
x Never park where parts of the hot exhaust system or catalytic converter could ignite flammable materials, such as dry grass, brush, leaves, spilled fuel, etc.
NOTICE
To help prevent damage to the vehicle if you should have to push it a short distance by hand, never push against spoilers, lights, body panels, windows, or similar parts. Concentrating force on these parts of the vehicle can cause expensive damage that may not always be obvi-ous right away.
The vehicle battery will be drained if the emergency flashers are on for a long time – even if the ignition is switched off.

Removing the wheel
x Review the checklist ⇒  Preparations for changing a wheel.
x Loosen the wheel bolts ⇒  Wheel bolts.
x Lift the vehicle ⇒  Lifting the vehicle with the vehicle jack.
x Completely unscrew and remove the previously loosened wheel bolts using the hexagonal socket
in the screwdriver handle ⇒ fig. 193. Place the wheel bolts on a clean surface.
x Remove the wheel.
Mounting a compact spare wheel
If the tire is a unidirectional tire, be sure to install it in the proper rolling direction ⇒  Tires and wheels.
x Place the compact spare wheel on the axle.
x Screw in the wheel bolts clockwise and tighten them slightly using the hexagonal socket in the screwdriver handle.
x Lower the vehicle with the jack.
x Use the lug wrench to firmly tighten all wheel bolts (turn clockwise) ⇒ . Do not tighten them in sequence! Tighten any wheel bolt to begin, then tighten the wheel bolt diagonally opposite the first bolt, and so forth.
x Install the wheel bolt caps, center wheel hubcap, or wheel cover, if any ⇒  Wheel trim.
WARNING
Wheel bolts that are tightened or installed improperly can come loose, causing loss of vehi-cle control, a crash, and serious personal injury.
x Always keep wheel bolts and threads in the wheel hub clean and free of oil and grease. The wheel bolts must turn easily and must be tightened with the right torque.
x Use the hexagonal socket in the screwdriver handle only to turn the wheel bolts when they are loose, never to loosen them or tighten them firmly.
WARNING
Improper use of a compact spare wheel can cause loss of vehicle control, a crash or other accident, and serious personal injury.
x Never use a compact spare wheel if it is damaged or worn down to the wear indicators.
x Never drive faster than 50 mph (80 km/h) with a compact spare wheel. Avoid full-throttle acceleration, heavy braking, and fast cornering!
x Never drive more than 125 miles (200 km) with a compact spare wheel that is installed on the front axle (drive axle).
x Replace the compact spare with a normal wheel and tire as soon as possible. Compact spare tires are designed for brief use only.
After changing a wheel

WARNING
Improper replacement of burned out headlights and other light bulbs can cause serious per-sonal injury.
x Stop! Always read and heed the WARNINGS before doing any work in the engine com-
partment ⇒  Working in the engine compartment. The engine compartment of any motor vehi-cle is a potentially dangerous area, and work in this area can lead to serious personal injury.
x HID – High Intensity Discharge (Xenon) headlights get power from a high voltage source that can cause severe personal injury and even death if handled improperly.
x H7 bulbs and HID – High Intensity Discharge (Xenon) headlights are under high pressure and can explode if handled improperly.
x Always let a burned out light bulb cool down before replacing it.
x Never replace a light bulb unless you are familiar with all of the necessary procedures. In particular, never remove a headlight unless you know exactly how to carry out the job and have the correct tools and light bulbs.
x If you are uncertain about what to do, have the work performed by an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified work-shop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon) headlights and H7 bulbs replaced by a qualified technician.
x Do not touch the glass of light bulbs with your bare hands. Fingerprints left on the bulb evaporate due to the heat when the bulb is switched on and cause the reflector to “cloud.”
x There are sharp edges on and around the headlight housing in the engine compartment and the rear light housing. Wear hand protection if you replace bulbs.
NOTICE
After replacing a headlight bulb or other light bulb, always make sure that the rubber covers or plastic caps have been properly and securely reinstalled to help prevent water from getting into the electrical connections and the headlight housing and damaging the electrical system.
LEDs cannot be replaced. Contact your authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.

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.
Failure of a single LED within a taillight is not indicated. However, the  indicator light will light up if all LEDs fail.

WARNING
Improper use of jumper cables when jump-starting a vehicle with a dead battery can cause the battery to explode, leading to serious personal injury. To help reduce the risk of battery explosion:
x All work on the batteries or the electrical system in your vehicle can cause serious acid burns, fires, or electrical shocks. Always read and heed the following WARNINGS and safety
precautions before working on the batteries or the electrical system ⇒  Vehicle battery.
x Always wear proper eye protection. Never lean over the vehicle battery.
x Attach the jumper cables in the correct order: first the positive cable, then the negative cable.
x Never connect the negative cable from the vehicle providing starting assistance to parts of the fuel system or to the brake hoses or brake lines.
x Never allow the non-insulated parts of the battery clamps to touch.
x Never allow the jumper cable attached to the positive battery terminal to contact metal parts of the vehicle.
x Check the battery acid level indicator window on the vehicle battery. Use a flashlight, never a match, cigarette lighter, or other open flame. If you cannot see the color of the win-dow clearly, or if it is light yellow or colorless, do not jump-start the vehicle. Get expert assis-tance.
x Avoid electrostatic discharge in the vicinity of the vehicle battery. Sparks may cause the hydrogen gas escaping from the vehicle battery to ignite.
x Never jump-start a vehicle with a battery that is damaged or frozen or that was frozen and has thawed. The battery can explode. Replace the battery instead.
x Always follow the instructions of the jumper cable manufacturer.
x Always make sure that the battery providing starting assistance has the same voltage as the dead battery (12 V) and about the same capacity (see battery label).
x Batteries give off explosive hydrogen gas. Always keep fire, sparks, open flame and smok-ing materials away from batteries.
x Never connect the negative cable from the other vehicle directly to the negative terminal of the dead battery. The hydrogen gas from the battery is explosive.
x Never short out the battery terminals by connecting the positive (+) and negative (-) termi-nals with each other.
