warning light VOLKSWAGEN JETTA 2018 Owner's Guide

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.
If the ignition is switched on, an acoustic warning sounds when low tire pressure is detected. If a system malfunction is detected, no acoustic warning sounds.
Driving for a longer period of time on rough roads or with a dynamic and sporty style can make the TPMS system temporarily unavailable. The indicator light will come on, signaling a malfunction, but will go out again once the road condition or driving style changes.

WARNING
Objects in the driver footwell can prevent the pedals from moving freely. This can cause loss of vehicle control and increase the risk of serious personal injuries.
x Always make sure that nothing can interfere with the pedals.
x Always fasten floor mats securely to the floor.
x Never put floor mats or other floor coverings on top of already installed floor mats.
x Always make sure that nothing can fall into the driver footwell while the vehicle is moving.
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.
NOTICE
x The defroster heating wires or antenna in the rear window can be damaged by hard or sharp things on the shelf below the rear window.
x Do not keep any food, medicine, or other items sensitive to heat or cold in the vehicle. They can be damaged or made unusable by heat or cold.
x Things that are made of transparent materials (such as eyeglasses, magnifying glasses, or transparent suction cups on the windows) can magnify sunlight and damage the vehicle.

WARNING
To reduce the risk of serious personal injury when starting and running the vehicle's engine:
x Never start the engine or let it run in a confined or enclosed area. Engine exhaust contains carbon monoxide, a poisonous, colorless, and odorless gas. Carbon monoxide can cause unconsciousness and death.
x Never start the engine or let it run if oil, fuel, or other flammable substances are under, around, or have leaked from the vehicle, for example, due to vehicle damage.
x Never leave the vehicle unattended with the engine running, especially when it is in gear. The vehicle could move suddenly or some other unexpected event could occur, resulting in property damage, fire, or personal injury.
x Never use starting assist fluids. Starting fluids can explode and can cause a “run-away” vehicle condition.
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 the vehicle where the hot exhaust system or catalytic converter could ignite flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
x Never apply additional undercoating or rust proofing on or near the exhaust manifold, exhaust pipes, catalytic converter, diesel particulate filter, or heat shields.
Indicator lights

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.
x Whenever stalled or stopped for repair, move the vehicle a safe distance off the road, turn on the emergency flashers, stop the engine, and use other warning devices to warn ap-proaching traffic.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
Vehicle key positions in the ignition switch

Fig. 123 In the ignition switch: Vehicle key positions.

WARNING
Rapid acceleration can cause skidding and loss of traction, especially on slippery roads, resulting in a loss of vehicle control, collisions, and serious personal injury.
x Only use the kick-down feature or fast acceleration if visibility, weather, road, and traffic conditions permit and other drivers will not be endangered by your driving and the vehicle's acceleration.
WARNING
Constant braking causes the brakes to overheat and even to fail leading to collisions and serious personal injury.
x Never “ride” the brakes or apply the brake pedal too often or too long.
x Riding the brakes will substantially reduce braking performance, increase stopping dis-tance, and can cause complete brake system failure.
NOTICE
x Never “ride” the brakes by keeping your foot on the brake pedal when you do not want to brake. This will make the brakes wear faster.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and shift into lower gear (manual or automatic transmission). This will let the vehicle use engine braking and reduce the load on the brakes. Otherwise, the brake system could overheat and even fail. Only use the brakes when you need them to slow the vehicle down more or to stop.
Warning and indicator lights

Automatic Shift Lock (ASL)
The Automatic Shift Lock (ASL) in Park (P) and Neutral (N) prevents drive positions from being en-gaged inadvertently, which would cause the vehicle to move.
To release the ASL, depress and hold the brake pedal with the ignition switched on. Press the release button on the selector lever at the same time.
The ASL is not engaged if the selector lever is moved quickly through Neutral (N) (e.g., when shifting from Reverse (R) to Drive (D)). This makes it possible to “rock” the vehicle backwards and forwards if it is stuck in snow or mud. The ASL engages automatically if the brake pedal is not depressed and the lever is in Neutral (N) for more than about 1 second and the vehicle is traveling no faster than about 3 mph (5 km/h).
In rare cases, the ASL may not engage on vehicles with a DSG® automated transmission. If this happens, power to the drive wheels will be interrupted to prevent the vehicle from moving unexpected-ly. The green indicator light K will blink and a text message will be displayed. To engage the Automat-ic Shift Lock (ASL):
x Depress and then release the brake pedal. Try to engage the ASL again.
WARNING
Moving the selector lever to the wrong position can cause loss of vehicle control, a collision, and serious personal injury.
x Never accelerate when moving the selector lever.
x When the engine is running and a drive position is engaged, the vehicle will start to move as soon as the brake pedal is released.
x Never shift into Reverse (R) or Park (P) when the vehicle is moving.
WARNING
Unintended vehicle movement can cause serious personal injury.
x Never get out of the driver's seat while the engine is running, especially when the trans-mission is in a drive gear. If you must leave your vehicle while the engine is running, always set the parking brake and shift the transmission into Park (P).
x Never leave the vehicle in Neutral (N). It will roll down hills, whether the engine is running or not.
x When the engine is running and a drive gear - Drive (D), Sport Drive (S), or Reverse (R) - has been selected, press and hold the brake pedal to keep the vehicle from moving. The ve-hicle may “creep” and move forward or backward even if the engine is idling slowly.
x Never shift into Reverse (R) or Park (P) when the vehicle is moving.
NOTICE
Even though the transmission is in Park (P), the vehicle may move a couple of inches (a few centimeters) forwards or backwards if you take your foot off the brake pedal after stopping the vehicle without first setting the parking brake.
If the selector lever is moved into Neutral (N) by mistake when the vehicle is moving, take your foot off the accelerator pedal. Wait until the engine speed has dropped to idle speed before moving the selector lever into a drive gear.

In any event, have the automatic transmission checked by an authorized Volkswagen dealer or author-ized Volkswagen Service Facility.
Overheating of the DSG® automated transmission
The DSG transmission may overheat, for example, due to frequent starts, extended “creeping,” or stop-and-go traffic. Overheating is indicated by the warning light

Lights up Possible cause Proper response
D=
Power steering assist is reduced.
Stop, restart the engine, and drive a short distance. If the yellow warning light does not come on again, you do not need to have the steering system checked. Otherwise, have the steering checked imme-diately by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Vehicle battery was disconnected and has been reconnected. Drive a short distance at about 10–12 mph (15–20 km/h).


Flashes Possible cause Proper response
D= Electronic steering column lock malfunc-tion.

WARNING
Parking improperly can cause serious personal injury.
x Never remove the key from the ignition switch while the vehicle is moving or rolling to a stop. The steering wheel will lock and you will not be able to steer or control the vehicle.
x Never park the vehicle where the hot exhaust system or catalytic converter could ignite flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
x Always apply the parking brake when parking your vehicle.
x Improper use of the parking brake can seriously injure you and your passengers.
x Never use the parking brake to slow down the vehicle when it is moving, except in an emergency. The stopping distance is much longer because only the rear wheels are braked. Always use the foot brake to stop the vehicle.
x Never activate the throttle manually from the engine compartment when the engine is running and the automatic transmission is in gear. The vehicle will start to move as soon as the engine speed increases even if the parking brake is on.
x Never leave children or anyone who cannot help themselves behind in the vehicle. They could release the parking brake and move the gear selector lever or gear shift, which could cause the vehicle to start moving. This can lead to a crash and serious personal injuries.
x Always take the key with you when you leave the vehicle. The engine can be started and vehicle systems such as the power windows can be operated, leading to serious personal injury.
x Never leave children, disabled persons, or anyone who cannot help themselves in the vehicle. The doors can be locked with the remote control vehicle key, trapping passengers in the vehicle in an emergency. For example, depending on the time of year, people trapped in the vehicle can be exposed to very high or very low temperatures.
x 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. Temperatures can quickly reach levels that can cause unconsciousness and death, particularly to small children.
NOTICE
x Always be careful when you park in areas with parking barriers or high curbs. These vary in height and could damage your bumper and related parts if the front of your vehicle hits a barri-er or curb that is too high while you are getting into or out of a parking spot. To help prevent damage, stop before the tires of your vehicle touch a parking barrier or curb.
x Always be careful when you enter a driveway or drive up or down steep ramps or over curbs or other obstacles. Parts of the vehicle close to the ground may be damaged (such as bumper covers, spoilers, and parts of the engine, suspension, and exhaust systems).
Warning and indicator lights

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.
WARNING
Driving with bad brakes can cause a collision and serious personal injury.
x If the brake warning light "2!+% or H does not go out, or lights up when driving, either the brake fluid level in the reservoir is too low or there is a fault in the brake system. Stop the
vehicle as soon as you can do so safely and get expert assistance ⇒ page 242, Brake fluid.
x If the brake warning light "2!+% or H lights up at the same time as the ABS warning light !"3 or J, the ABS may not be working properly. This could cause the rear wheels to lock up rela-tively quickly during braking. Rear wheel brake lock-up can cause loss of vehicle control.
x If you believe the vehicle is safe to drive, drive slowly and very carefully to the nearest authorized Volkswagen dealer, authorized Volkswagen Service Facility, or other qualified workshop and have the brake system inspected. Avoid sudden hard braking and steering.
x If the ABS indicator light !"3 or J does not go out, or if it lights up while driving, the ABS system is not working properly. The vehicle can then be stopped only with the standard brakes (without ABS). You will not have the protection ABS provides. Contact your author-ized Volkswagen dealer or an authorized Volkswagen Service Facility as soon as possible.
x If the brake pads are worn or you notice changes in the way the vehicle brakes, immedi-ately contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility to have the brake pads checked and, if necessary, replaced.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
