Introduction

If your engine does not start because the vehicle

battery is dead, your vehicle's battery can be con-

nected 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

→ page 256, Vehicle battery.

Preparations

— Switch off the headlights, the ignition, and all

electrical consumers.

— Open the appropriate fuse box → page 231, Fuses

in the vehicle, → page 232, Fuses in the engine

compartment.

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).

Identifying a blown fuse

—

For blade fuses (ATO , MINI ): Remove the fuse

and shine a flashlight on it. This makes it easier to

tell if the fuse has blown. A blown blade fuse has

metal strips that have burned through, which you

can see through the transparent housing from

ment.

above and from the side → fig. 158

WARNING

—

For cartridge fuses (JCASE ): Shine a flashlight on

the fuse. This makes it easier to tell if the fuse has

blown. A blown cartridge fuse has metal strips

that have burned through, which you can see

through the transparent housing from above

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.

gen gas given off by the dead battery to ex-

plode.

Never attach the negative cable from the vehi-

cle providing starting assistance to any part of

the fuel system or to the brake hoses or brake

lines.

If you get battery acid in your eyes or on your

skin, immediately rinse with cold water for sev-

eral minutes and get medical attention immedi-

ately. If you swallow any battery acid, get medi-

cal attention immediately.

Never allow the non-insulated parts of the bat-

tery 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 ca-

ble manufacturer.

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:

NOTICE

To help prevent extensive damage to the vehicle

electrical system, read and heed the following:

All work on the batteries or the electrical sys-

tem 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 → page 256, Vehicle bat-

tery.

Connecting jumper cables improperly can cause

a short circuit and do expensive damage to the

vehicle's electrical system.

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 elec-

trical system damage.

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).

Jump-start terminal

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).

Please read the introductory information and

heed the Warnings and Notice

233.

and on page

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 explo-

sive! Always keep fire, sparks, open flame, and

smoking materials far away from vehicle batter-

ies. Never use a mobile telephone while con-

necting or disconnecting jumper cables.

Jump-start batteries only in well-ventilated

areas. Batteries give off highly explosive hydro-

gen 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 con-

necting the positive (+) and negative (-) termi-

nals with each other.

speed.

The dead battery must be properly connected to the

vehicle's electrical system.

— 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 en-

gine does not start within about 10 seconds, turn

off the ignition and wait at least 1 minute; then

try again. If the engine still does not start, get

professional assistance.

Make certain that the vehicles are not touching each

other. Otherwise, electric current could flow as soon

as the positive battery terminals (+) are connected.

Use longer jumper cables if necessary.

The clamps on the jumper cables must have good

contact to bare metal on the battery terminals.

If the engine does not start, stop the process after

10 seconds and repeat after about 1 minute. If the

engine still does not start, get professional assis-

tance.

Before removing the jumper cables

— Switch off the headlights (if they are on).

— 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.

The procedure for attaching and for removing the

jumper cables is described below. Perform each of

the following steps only in the order described,
