light VOLKSWAGEN JETTA 2017 Workshop Manual

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

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

H

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.
Parking brake

Fig. 133 Between the front seats: Parking brake.

Setting the parking brake
x Pull the parking brake lever up firmly.
x When the ignition is on, the indicator light G or 0!2+ appears in the instrument cluster display to
show that the parking brake is engaged ⇒  Warning and indicator lights.
Releasing the parking brake
x Pull the lever up slightly and press the release button ⇒ fig. 133 (arrow).
x While holding the release button down, move the lever all the way down.
WARNING
Improper use of the parking brake can cause accidents and severe injuries.
x Never use the parking brake to slow down the vehicle when it is moving, except in an emergency. Braking distance is much longer, since only the rear wheels are braked. Always use the foot brake.
x Never drive with the parking brake partially engaged. This can cause the brake to overheat and negatively affect the brake system. It will also cause the rear brake pads to wear prema-turely.
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 even if the parking brake is engaged.
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 firmly setting the parking brake.
A warning signal sounds if you drive faster than about 4 mph (6 km/h) with the parking brake engaged.
Parking

Wet brakes (for example, after driving through water or washing the vehicle or after heavy rainfall) will not brake as well. Stopping distances will be longer when brake discs are wet or, in winter, even icy. Wet or icy brakes must be dried as soon as possible by carefully applying the brakes a couple of times while traveling at a relatively high speed. Make sure nobody is behind you and that you do not endan-
ger yourself or others ⇒ .
Brakes coated with road salt also react slower and need longer stopping distances. If there is salt on the roads and you are not braking regularly, brake carefully and gently from time to time to remove any
salt coating from the brake discs and pads ⇒ .
Brake disc corrosion (rust) and dirt buildup on the brake pads are more likely to occur if the vehicle is not driven much or is driven only for short distances with little braking. If the brakes have not been used and there is some rust on the discs, clean the brake discs and pads once in a while by carefully braking a couple of times while driving at relatively high speed to help clean the brake discs and pads.
Make sure nobody is behind you and that you do not endanger yourself or others ⇒ .
Brake system malfunction
If you brake and find that the vehicle doesn't brake nearly as well as it used to (sudden increase in stopping distance), a brake circuit may have failed. The brake warning light H or "2!+% will light up and a message may appear in the instrument cluster display. If you believe the vehicle is safe to drive, immediately take it to the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for repair. Drive slowly and very carefully, allow for the longer stopping distance, and be ready to push longer and harder on the brake pedal to slow the vehicle down.
Brake booster
The brake booster works only when the engine is running. It increases the force on the brakes above and beyond the pressure put on the brake pedal by the driver.
If the brake booster is not working, or if the vehicle has to be towed, you will have to push the brake pedal harder to make up for the lack of booster assistance and the resulting longer stopping distance
⇒ .
WARNING
New brake pads do not provide maximum braking performance.
x New brake pads do not have the best stopping power for the first 185 miles (300 km) and must be “broken in.” You can compensate for the slightly reduced braking force by putting more pressure on the brake pedal.
x Drive with extra care while the new brake pads are being broken in. This reduces the risk of collisions and serious personal injuries due to a loss of control over the vehicle.
x Never follow other vehicles too closely or put yourself into other situations that might require sudden, hard braking, especially when the brake pads have not been broken in.
WARNING
Overheated brakes will reduce the vehicle's stopping power and increase stopping distances considerably.
x When driving downhill, the brakes have to work especially hard and heat up quickly.
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 over-heat and possibly fail. Only use the brakes when you need them to slow the vehicle down more or to stop.
x A damaged front bumper or a non-standard spoiler can reduce airflow to the brakes and make them overheat.
