Checklist
For your own safety and that of your passengers, carry out the following steps in the order listed ⇒ :
1. Park the vehicle at safe distance from traffic and on a suitable surface ⇒ .
2. Switch on emergency flashers by pressing the  switch ⇒ fig. 327.
3. Apply the electronic parking brake to help prevent the vehicle from moving.
4. Shift the transmission into Park (P)
5. Stop the engine and remove the key from the ignition switch
6. Have all passengers exit and go to a safe location away from moving traffic, such as behind a guard rail.
7. Take all vehicle keys with you when leaving your vehicle.
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 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 and can cause a fire 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 ⇒  12 Volt vehicle bat-tery.
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 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 explo-sive! Always keep fire, sparks, open flame, and smoking materials far away from vehicle bat-teries. 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 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 terminal (+) 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 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.

The procedure for attaching and for removing the jumper cables is described below. Perform each of the following steps only in the order in which it is described.
Before you begin
d Switch off the ignition in both vehicles.
d Open the hoods of both vehicles.
d Remove the cover from the positive terminal on your vehicle and, if necessary, the battery cover of the other vehicle.

Starting the engine
1. Start the engine of the vehicle with the good battery that is providing help and let it run at idle speed.

2. Turn 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
1. Switch off the headlights (if they are on).
2. In the vehicle with the dead battery, switch on the heater fan and the rear window defroster. This helps tit minimize voltage spikes when the cables are disconnected.
Removing the jumper cables
1. Before you remove the jumper cables, switch off the headlights (if they are on).
2. 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 jumper cables are disconnected.
3. With the engine running, remove the jumper cables in reverse order to the way they were con-nected. Specifically:
– Disconnect the black (–) cable from the vehicle with the dead battery.
– Disconnect the black (–) cable from the other vehicle (vehicle with the good battery).
– Disconnect the red (+) cable from the other vehicle (vehicle with the good battery).
– Disconnect the red (+) cable from the vehicle with the dead battery.
4. Turn off the heater fan and the rear winder defroster on the vehicle with the dead battery.
