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 sm/+e 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

8. Set up a warning triangle or other warning device in order to alert other motorists and cyclists.
9. Let the engine cool down and get expert assistance if necessary.
If the emergency flashers are on, use the turn signal lever to indicate a direction or lane change, for
example when the vehicle is being towed. This temporarily interrupts the emergency flashers.
Switch on the emergency flashers when:
x Traffic suddenly slows down or stops in front of you to warn those approaching from behind.
x In any emergency situation.
x If the vehicle breaks down.
x When being towed.
Always obey traffic laws that govern the use of emergency flashers where you are driving.
If the emergency flashers are not working, a different method – as permitted by law – must be used to
alert other motorists and cyclists to the breakdown.
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
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot.
They can cause fires and serious personal injury.
x Never park where parts of the hot exhaust system or catalytic converter could ignite
flammable materials, such as dry grass, brush, leaves, spilled fuel, etc.
The vehicle battery will be drained if the emergency flashers are on for a long time – even if the
ignition is switched off.

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
battery label).
x 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).
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
explosive! Always keep fire, sparks, open flame, and sm/+ing materials far away from vehicle
batteries. Never use a cellular telephone while connecting or disconnecting jumper cables.
x Jump-start batteries only in well-ventilated areas. Batteries give off highly explosive
hydrogen 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 (-)
terminals 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
explode.
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
following:
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.

Using jumper cables

Fig. 165 Diagram for attaching the jumper cables: Dead battery 1 and booster battery 2.

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., Vehicle battery.
