Start engine VOLKSWAGEN JETTA 2017 Service Manual

WARNING
Improperly lifting your vehicle with a workshop hoist or a floor jack can cause the vehicle to fall off and cause serious personal injury.
x Always read and heed the operating instructions from the floor jack manufacturer and legal regulations if necessary before using the floor jack to lift the vehicle.
x Never let anyone stay in the vehicle when it is being lifted or when it is off the ground.
x Always lift your vehicle only at the designated lift points shown in the illustrations
⇒ fig. 172 and ⇒ fig. 173. Not using the designated lift points can cause the vehicle to fall off the floor jack when heavy parts such as the engine or transmission are removed.
x Always make sure that the vehicle's lift points lie as flat as possible and centered on the carrier plates of the floor jack.
x Never start the engine when you have raised the vehicle on the floor jack. The engine vibrations and vehicle movements could knock the vehicle off the floor jack.
x If you must work under a vehicle raised on a floor jack, always make sure that the vehicle is safely supported on safety stands intended for that purpose that are strong enough to support the weight of the vehicle.
x Never use the floor jack as a ladder or step ladder.
x Always make sure that the weight of the vehicle is not heavier than the lifting capacity of the floor jack and safety stands being used.
NOTICE
x To help prevent serious vehicle damage, never lift the vehicle by the engine oil pan, trans-mission housing, or by the front or rear axles or suspension.
x To help prevent damage to the underbody or chassis, always insert a rubber pad between the hoist and the lifting points. In addition make sure the lifting arms have enough clearance.
x The lifting arms should not touch side sills or other parts of the vehicle.

WARNING
Changing a wheel, especially on the side of the road, can be dangerous. To help reduce the risk of serious personal injury:
x Always stop the vehicle as soon as it is safe to do so. Move the vehicle a safe distance off the road where it is safe to change the wheel.
x Always make sure that all passengers, especially children, are in a safe place outside the vehicle and away from the vehicle and traffic (such as behind a guard rail).
x Turn on the emergency flashers and set up another warning device about 25 yards (25 meters) behind the vehicle to warn approaching traffic.
x Change a wheel by yourself only if you are familiar with the necessary steps. Otherwise, get expert assistance.
x Always switch the engine off, firmly apply the parking brake, and shift the transmission into Park (P) (automatic transmission) or any gear (manual only) to help prevent the vehicle from moving suddenly and slipping off the jack.
x Always make sure that the ground is level and firm. If necessary, place the jack on a large and sturdy board or on a similar ground support.
x Always block the wheel diagonally opposite the wheel being changed with chocks or other similar things.
x If you are towing a trailer, always unhitch it from your vehicle before starting to change the wheel. Always apply the trailer brakes firmly and make sure the trailer cannot move unin-tentionally.
x Always use proper and undamaged tools when changing a wheel.
x Once a wheel is lifted off the ground, having the transmission in Park (P) or in gear will not prevent sudden vehicle movement.
x Always use a jack that has been approved by the manufacturer for your vehicle. Never use other jacks, even if they have been approved for use on other Volkswagen models.
x To reduce the risk of losing control, crashes, and serious personal injuries, never loosen the screws on rims with threaded rim rings.
x After changing a wheel, have the wheel bolt tightening torque checked with an accurate torque wrench.
x After changing a wheel or tire, reset the Tire Pressure Monitoring System ⇒  Tire Pressure Monitoring System (TPMS).
Preparations for changing a wheel

WARNING
Improper use of your vehicle jack can cause the vehicle to fall off the jack leading to serious personal injury. To help reduce the risk of serious personal injury:
x Use only jacks approved by Volkswagen for the vehicle. Other jacks might slip, even those approved for other Volkswagen models, but not for your vehicle.
x Always set up the jack on firm and level ground. The vehicle may slip off the jack if the jack is resting on soft or sloping ground. If necessary, place a sturdy board under the jack.
x On a hard, slippery surface (such as a tiled floor), use an anti-skid rubber mat or some-thing similar to help prevent the jack from slipping.
x Position the jack only at the described vehicle lift points. Before you raise your vehicle, always make sure the jack claw properly grips the vertical rib under the sill so that the jack
does not slip off when you are raising the vehicle ⇒ fig. 192.
x Never have any part of your body (such as your arm or leg) under the vehicle when it is supported by the jack. Never let other persons have any part of their body under the vehicle, either!
x If you must work under a vehicle raised on a floor jack, always make sure that the vehicle is safely supported on safety stands intended for that purpose that are strong enough to support the weight of the vehicle.
x Never lift the vehicle when it is tilted or inclined to one side or the engine is running.
x Never lift the vehicle when more than 1 tire is flat or damaged.
x Do not start the engine while the vehicle is supported by a jack. Engine vibrations may cause the vehicle to slip off the jack.
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
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 make sure that the battery providing starting assistance (the booster battery) has the same voltage as the dead battery (12 V) and about the same amperage capacity (see bat-tery label).
x Never jump-start a vehicle with a thawed or frozen vehicle battery. The battery can ex-plode. A dead battery can freeze at temperatures around +32 °F (0 °C).
x A battery that is frozen or was frozen, but has since thawed, must be replaced.
x When the vehicle battery is jump-started, it gives off hydrogen gas, which is highly explo-sive! Always keep fire, sparks, open flame, and smoking materials far away from vehicle bat-teries. Never use a mobile telephone while connecting or disconnecting jumper cables.
x Jump-start batteries only in well-ventilated areas. Batteries give off highly explosive hy-drogen gas during jump-starting.
x Always route the jumper cables so that they cannot get caught in any moving parts in the engine compartment.
x Never short out the battery terminals by connecting the positive (+) and negative (-) termi-nals with each other.
x Never connect the negative cable from the other vehicle directly to the negative terminal of the dead battery, as this may cause the hydrogen gas given off by the dead battery to ex-plode.
x Never attach the negative cable from the vehicle providing starting assistance to any part 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 Always follow the instructions of the jumper cable manufacturer.
NOTICE
To help prevent extensive damage to the vehicle electrical system, read and heed the follow-ing:
x Connecting jumper cables improperly can cause a short circuit and do expensive damage to the vehicle's electrical system.
x Do not let the vehicles touch each other while the jumper cables are connected. If they do, electrical current may flow between the vehicles when the positive (+) terminals are connected, causing electrical system damage.

Attaching jumper cables
1. Switch off the ignition in both vehicles ⇒  Starting and stopping the engine.
2. Open the battery cover in the engine compartment if the battery has a cover ⇒  Vehicle battery.
3. Attach one end of the red jumper cable to the positive terminal (+) of the dead battery: (1) ⇒ .
4. Attach the other end of the red jumper cable to the positive terminal (+) of the good battery (booster battery): (2).
5. Attach one end of the black jumper cable to the negative terminal (-) of the booster battery: (2)
⇒ fig. 199.
6. Attach the other end of the black jumper cable (3) to a bare metal part of the vehicle with the dead battery. This part should be connected directly to the engine block. You may also attach the
cable to the engine block itself or to the towing eye installed on the front of the vehicle ⇒ page 405,
Towing. Attach the clamp to a point that is as far away as possible from the dead battery (1) ⇒ .
On vehicles with a 1.8 liter engine, see ⇒ fig. 198 (-).
7. Route the jumper cables so that they cannot get caught in any moving parts in the engine com-partment of either vehicle.
Starting the engine
x Start the engine of the vehicle with the good battery that is providing help and let it run at idle speed.
x Turn on the ignition of the vehicle with the dead battery. If the engine starts, wait 2 to 3 minutes
until it “runs smoothly” before removing the jumper cables as described below ⇒ . If the engine does not start within about 10 seconds, turn off the ignition and wait at least 1 minute; then try again.
Before removing the jumper cables
x Switch off the headlights (if they are on).
x In the vehicle with the dead battery, switch on the heater fan and the rear window defroster. This helps to minimize voltage spikes when the cables are disconnected.
Removing jumper cables
With the engine running, remove the jumper cables in reverse order to the way they were connected.
1. Disconnect the black (-) cable from the vehicle with the dead battery.
2. Disconnect the black (-) cable from the other vehicle (vehicle with the good battery).
3. Disconnect the red (+) cable from the other vehicle (vehicle with the good battery).
4. Disconnect the red (+) cable from the vehicle with the dead battery.
5. Close the battery cover.
6. If necessary, unscrew the towing eye on the front of the vehicle ⇒  Installing the front towing eye.

When not to tow your vehicle
In the following situations, the vehicle cannot be towed and must be transported on a flatbed truck or trailer:
x If transmission fluid has leaked out of the transmission.
x If there is little or no oil in the transmission because of damage to your vehicle, it must be moved with the drive wheels off the ground.
x If the front and rear wheels cannot turn.
x When the vehicle battery is dead, because the steering may remain disabled and it may not be possible to release the electronic steering column lock.
x If you have to tow an automatic transmission vehicle more than 30 miles (50 km).
x If the steering or the wheel clearance might be impaired, for example, after an accident.
Towing other vehicles
x Obey all legal requirements
x Read and heed all towing information in the owner's manual for the other vehicle.
A vehicle can be towed only if the electronic steering column lock is released. In case of a power loss or malfunctions of the electrical system, the engine may have to be jump-started in order to re-lease the electronic steering column lock.
