Replacing fuses

Introduction to the subject

In this chapter you will find information on the following subjects:

⇒ Fuses in the vehicleꢀ

⇒ Replacing blown fusesꢀ

Due to ongoing development of the vehicle, conﬁguration-dependent allocation of fuses and the combined fuse protection of multiple loads with one fuse, an up-to-

date overview of the fuse location per load is not possible at the time of printing. Detailed information regarding fuse box layout is available from authorized

Volkswagen dealers and authorized Volkswagen Service Facilities.

In general, one fuse can protect several loads. One load can also be protected by several fuses.

Find out why the fuse blew and correct the problem before replacing a blown fuse. If a newly replaced fuse blows again after a short time, the electrical system

should be checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.

WARNING

High voltage systems in the engine compartment can cause electrical shocks, severe burns, and even death!

Never touch ignition cables. Never touch other components of the high voltage electronic ignition system.

Avoid short circuits in the electrical system.

WARNING

Using the wrong fuse, using a blown fuse that has been repaired, and using metal objects in place of fuses to complete the electrical connection in the circuit

can cause fires and serious personal injury.

Never replace a fuse with one that has a higher amp rating. Replace a blown fuse only with a fuse of the same amperage (same color and same imprint)

and same overall size.

Never repair fuses.

Never replace fuses with a metal strip, a paper clip, or a similar object.

NOTE

To help prevent damage to the electrical system, switch off all lights and accessories, switch off the ignition, and remove the key from the ignition switch (if

applicable) before replacing a fuse.

If a fuse is replaced with a fuse with higher amperage, this can also cause damage at different locations in the electrical system.

273

Open fuse boxes must be protected from dirt and moisture. Dirt and moisture in fuse boxes can cause damage to the electrical system.

Opening the fuse box in the instrument panel

Pull the lower part of the cover straight out (in the direction of the arrow ⇒ Fig. 197ꢀ) and remove the cover from the bottom. This action may require moderate

274

force.

To install, fit the cover on the hinges at the bottom of the opening. Guide the cover into the instrument panel by pushing in the direction opposite of the arrow

⇒ Fig. 197ꢀ until you can hear it latch into place.

Opening the fuse box in the engine compartment

Open the engine hood

⇒ In the engine compartmentꢀ.

Press the release tabs in the direction of the arrows ⇒ Fig. 198ꢀ to unlock the fuse box cover ①.

Remove the cover upward.

To install push the cover onto the fuse box. The locking tabs must latch with an audible click.

In some vehicles, there are plastic tweezers for removing fuses on the inside of the fuse box cover ⇒ Fig. 198②ꢀ.

NOTE

To help prevent vehicle damage, be careful when removing fuse box covers and be sure to reinstall them properly.

Open fuse boxes must be protected from dirt and moisture. Dirt and moisture in fuse boxes can cause damage to the electrical system.

The vehicle contains other fuses in addition to those mentioned in this section. Have these fuses replaced by an authorized Volkswagen dealer or an

authorized Volkswagen Service Facility.

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

Preparations

Switch off the headlights, the ignition, and all electrical consumers.

Open the appropriate fuse box ⇒ Fuses in the vehicleꢀ.

Identifying a blown fuse

Shine a flashlight on the fuse. This makes it easier to tell if the fuse has blown.

A blown blade fuse (ATO^®, MINI^®) has metal strips that have burned through, which you can see through the transparent housing from above and from the

side ⇒ Fig. 199ꢀ

A blown cartridge fuse (JCASE^®) has metal strips that have burned through, which you can see through the transparent housing from above ⇒ Fig. 199ꢀ

Replacing a fuse

In some vehicles, there are plastic tweezers for removing blade fuses on the inside of the fuse box cover in the engine compartment.

Open the fuse box cover in the engine compartment ⇒ Fuses in the vehicleꢀ and remove the plastic tweezers.

Depending on the type of fuse, slide the tweezers ⇒ Fig. 200ꢀ ① or ⇒ Fig. 200ꢀ ① onto the fuse from the side.

Pull out the fuse.

If the fuse is blown, replace the fuse with a new fuse of the same amperage (same color and same imprint) and same size ⇒ ꢀ.

275

Clip the plastic tweezers back into the holder inside the fuse box cover.

Replace the fuse box cover.

NOTE

If a fuse is replaced with a fuse with higher amperage, then damage can occur at various places in the electrical system.

Jump-starting

Introduction to the subject

In this chapter you will find information on the following subjects:

⇒ Jump-start terminalꢀ

⇒ Using jumper cablesꢀ

If your engine does not start because the vehicle battery is dead, your vehicle's battery can be connected to the battery of another vehicle to start your engine

(jump-starting). Check the battery acid level indicator on the vehicle battery before jump-starting ⇒ Vehicle batteryꢀ.

You must use jumper cables that meet recognized industrial standards (check information provided by the jumper cable manufacturer). For vehicles with gasoline

engines, the cross-section of the jumper cable wire must be at least 0.038 in. ²(25 mm²), or about 3 ga. (AWG).

WARNING

Working on the batteries or the electrical system in your vehicle can cause serious acid burns, fires, or electrical shock.

Always keep children away from battery acid and vehicle batteries in general.

Sulfuric battery acid is very corrosive and can cause blindness and damage to unprotected skin. Never let battery acid or lead particles contact your eyes,

skin, and clothing.

Never lean over a vehicle battery. Always wear protective gloves and eye protection. To reduce your risk of injury, never tilt the batteries; acid could spill out

through the vents and burn you.

A highly explosive mixture of gases is given off when the battery is being charged.

Always avoid fires, sparks, open flame, and smoking. 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.

If you get battery acid in your eyes or on your skin, immediately rinse with cold water for several minutes and get medical attention immediately. If you

swallow any battery acid, get medical attention immediately.

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:

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 batteryꢀ.

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 battery label).

Never jump-start a vehicle with a thawed or frozen vehicle battery. The battery can explode. A dead battery can freeze at temperatures around +32 °F

(0 °C).

A battery that is frozen or was frozen, but has since thawed, must be replaced.

When the vehicle battery is jump-started, it gives off hydrogen gas, which is highly explosive! Always keep fire, sparks, open flame, and smoking materials

far away from vehicle batteries. Never use a mobile telephone while connecting or disconnecting jumper cables.

Jump-start batteries only in well-ventilated areas. Batteries give off highly explosive hydrogen gas during jump-starting.

Always route the jumper cables so that they cannot get caught in any moving parts in the engine compartment.

Never short out the battery terminals by connecting the positive (+) and negative (-) terminals with each other.

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 explode.

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.

Never allow the non-insulated parts of the battery clamps to touch.

Never allow the jumper cable attached to the positive battery terminal to contact metal parts of the vehicle.

Always follow the instructions of the jumper cable manufacturer.
