2013 VOLKSWAGEN GOLF check engine light

Opening the engine hood
x Before you open the hood, make sure that the windshield wiper arms are resting on the windshield
⇒ .
x Open the driver door and pull the inside hood release lever in the direction of the arrow ⇒ fig. 150.
The engine hood is released from its latch by a spring ⇒ .
x Push the outside hood release lever ⇒ fig. 151 (arrow) and lift the hood all the way up. A gas-filled
strut will hold the hood up.
Closing the engine hood
x Pull the hood down to overcome the resistance of the gas-pressure strut ⇒ .
x Lower the engine hood by hand until it is about 1 ft. (30 cm) above its latch and then let it drop into
place to latch it. Do not push down on it afterwards!
If the hood does not close completely, open it again and close it properly.
When the hood is properly closed, you can see that it fits flush with the other body parts. The indicator
light in the instrument cluster will go out
WARNING
If the hood is not closed properly, it could fly up and block your view while you are driving.
This can lead to a crash and serious personal injuries.
x After closing the engine hood, check that the hood release lever is properly latched into
the hood latch. The engine hood must be flush with the surrounding auto body parts.
x If you ever notice that the hood latch is not properly secured when the vehicle is moving,
stop at once and close it.
x Never let anyone get in the way of the hood when closing it.
NOTICE
x Make sure the windshield wiper arms are resting on the windshield before you open the
hood. Otherwise, the windshield wipers and the hood may be damaged.
x Always put the windshield wiper arms down against the windshield before driving the
vehicle.
NOTICE
Before opening or closing the engine hood, make sure there is enough room to do so, for
example when the vehicle is in a garage.

WARNING
Working on the batteries or the electrical system in your vehicle can cause serious acid
burns, fires, explosions, or electrical shocks. Always read and heed the following WARNINGS
and safety precautions before working on the batteries or the electrical system.
x Before working on the electrical system, always switch off the ignition and all electrical
consumers and disconnect the negative (-) cable from the standard 12 Volt battery.
x When you change a light bulb, always switch off the light first.
x Always keep children away from battery acid and vehicle batteries in general.
x Always wear eye protection. Never let battery acid or lead particles come into contact with
your eyes, skin, or clothing.
x Sulfuric battery acid is very corrosive. It can burn unprotected skin and cause blindness.
Always wear protective gloves and eye protection. To reduce your risk of injury, never tilt the
batteries, as this could spill acid through the vents and burn you.
x If you get battery acid in your eyes or on your skin, immediately rinse with cold water for
several minutes and then get immediate medical attention. If you swallow any battery acid,
get medical attention immediately.
x When disconnecting the batteries from the vehicle electrical system, always disconnect
the negative cable (-) first and then the positive cable (+).
x Always switch off all electrical consumers before reconnecting 12 Volt batteries.
Reconnect the plus cable (+) first and then the negative cable (-). Never reverse the polarity of
the connections. This could cause a fire.
x A highly explosive mixture of gases is given off when the battery is being charged.
x Do not smoke and avoid fires, sparks, and open flames when working. Never create
sparks or electrostatic charges when handling cables and electrical equipment. Never short
circuit the battery terminals. High-energy sparks can cause serious personal injury.
x Never use or attempt to charge a damaged or frozen battery, or a battery that was frozen
but has thawed. Charging a frozen or thawed battery could cause explosions and chemical
burns! Replace damaged or frozen vehicle batteries immediately. A dead battery can freeze at
temperatures around +32 °F (0 °C).
x If the battery has a vent line or tube, make sure that it is properly connected to the battery.
WARNING
California Proposition 65 Warning
x Battery posts, terminals, and related accessories contain lead and lead components,
chemicals known to the State of California to cause cancer and reproductive harm. Wash
your hands after handling.
NOTICE
x Do not expose the vehicle battery to direct sunlight for an extended period of time as
ultraviolet rays may damage the battery housing.
x If the vehicle is left standing in the cold for a long time, protect the vehicle battery from
freezing. A battery will be permanently damaged by freezing.
Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle
battery has been replaced may change or delete system settings (including time, date, personal
convenience settings, and programming). Check the settings and correct as necessary once the
vehicle battery has built up a sufficient charge.

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
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 248, 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
window clearly, or if it is light yellow or colorless, do not jump-start the vehicle. Get expert
assistance.
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
smoking 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 (-)
terminals with each other.
