If your vehicle has a discharged battery, it can be jump started using a set of jumper cables and a battery in another vehicle, or by using a portable battery booster pack. Jump starting can be dangerous if done improperly, so please follow the procedures in this section carefully.
Do not attempt jump starting if the battery is frozen. It could rupture or explode and cause personal injury.
Do not use a portable battery booster pack or any other booster source with a system voltage greater than 12 Volts or damage to the battery, starter motor, alternator or electrical system may occur.
When using a portable battery booster pack, follow the manufacturer's operating instructions and precautions.
For Hybrid Vehicles
The vehicle requires its 12 Volt battery power to turn-on the vehicle's high voltage battery. The high voltage battery is used to charge the 12 Volt battery, provide electric vehicle operation, and to start the vehicle's gas engine. If the 12 Volt battery has been discharged, the vehicle can be jump started using a set of jumper cables and a battery in another vehicle or by using a portable battery booster pack.
If the vehicle's high voltage battery has also been discharged, it will need to be recharged to a minimum operating State Of Charge (SOC) before the vehicle can be started:
If the vehicle can be connected to a Level 1 or Level 2 charger where it is currently parked, the vehicle will still require a jump start to allow the vehicle to begin the battery charging process. Once the vehicle charging has begun (indicated by the charge status indicator on top of the vehicle's instrument panel), the jumper cables can be removed from the vehicle jump posts.
If the vehicle cannot be connected to a Level 1 or Level 2 charger where it is currently parked, the vehicle can be moved by connecting 12 Volt power to the vehicle's jump posts and then shifting the transmission from PARK (P) into NEUTRAL (N). Power provided by the jumper cables will also allow the Electric Park Brake to be released. Carefully move the vehicle to a Level 1 or Level 2 charge location. While the vehicle is being moved, the external 12 Volt power must remain connected to the vehicle jump posts.
Be careful when moving the vehicle - ensure that control of the vehicle is maintained. Also, ensure that vehicle is secured to prevent unintentional movement during and after moving the vehicle. If the external 12 Volt power becomes disconnected from the vehicle jump posts or there is an interruption of the 12 Volt power while moving the vehicle, the vehicle's transmission may engage PARK. Do not allow the jumper cables to come in contact with each other or to the vehicle, this will result in a short.
When the vehicle is at the charging location, shift the transmission back to PARK, apply the Electric Park Brake, and start the high voltage battery charging. Once the vehicle has been secured against unintentional movement and high voltage battery charging has been initiated, the jumper cables can be removed from the vehicle jump posts.
Only use the positive battery post on the main battery to jump start your vehicle. Serious injury or death could result if you attempt to jump start using the supplemental battery.
Battery gas is flammable and explosive. Keep flame or sparks away from the battery. Do not use a booster battery or any other booster source with an output greater than 12 Volts. Do not allow cable clamps to touch each other.
Never use a fast battery charger to start the engine, as this could damage the electronic systems of your vehicle, particularly the ignition and engine fuel supply control units.
If a “fast charger” is used while the battery is in the vehicle, disconnect both vehicle battery cables before connecting the charger to the battery.
Battery posts, terminals, and related accessories contain lead and lead compounds. Wash hands after handling.

Positive (+) Battery Post

Positive (+) Battery Post (6.4 Engine)
The positive (+) battery post is covered with a protective cap. Lift up on the cap to gain access to the post.
See the following steps to prepare for jump starting:
Apply the parking brake, shift the automatic transmission into PARK (P) (manual transmission in NEUTRAL) and turn the ignition OFF.
Turn off the heater, radio, and all electrical accessories.
Pull upward and remove the protective cover over the positive (+) battery post.
If using another vehicle to jump start the battery, park the vehicle within the jumper cable’s reach, apply the parking brake and make sure the ignition is OFF.
Do not allow vehicles to touch each other as this could establish a ground connection and personal injury could result.
Take care to avoid the radiator cooling fan whenever the hood is raised. It can start anytime the ignition switch is ON. You can be injured by moving fan blades.
Remove any metal jewelry such as rings, watch bands and bracelets that could make an inadvertent electrical contact. You could be seriously injured.
Batteries contain sulfuric acid that can burn your skin or eyes and generate hydrogen gas which is flammable and explosive. Keep open flames or sparks away from the battery.

Supplemental Battery – If Equipped
Failure to follow this jump starting procedure could result in personal injury or property damage due to battery explosion.
Connecting The Jumper Cables
Connect the positive (+) end of the jumper cable to the positive (+) post of the discharged vehicle.
Connect the opposite end of the positive (+) jumper cable to the positive (+) post of the booster battery.
Connect the negative (-) end of the jumper cable to the negative (-) post of the booster battery.
Connect the opposite end of the negative (-) jumper cable to a good engine ground. A “ground” is an exposed metallic/unpainted part of the engine, frame or chassis, such as an accessory bracket or large bolt. The ground must be away from the battery and the fuel injection system.
Do not connect the jumper cable to the negative (-) post of the discharged battery. The resulting electrical spark could cause the battery to explode and could result in personal injury.

Jump Starting Label
Make sure at all times that unused ends of jumper cables are not contacting each other or either vehicle while making connections. Failure to follow these procedures could result in damage to the charging system of the booster vehicle or the discharged vehicle.
Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start the engine in the vehicle with the discharged battery.
Do not run the booster vehicle engine above 2,000 RPM since it provides no charging benefit, wastes fuel, and can damage booster vehicle engine.
Once the engine is started, remove the jumper cables in the reverse sequence.
Disconnecting The Jumper Cables
Disconnect the negative (-) end of the jumper cable from the engine ground of the vehicle with the discharged battery.
Disconnect the opposite end of the negative (-) jumper cable from the negative (-) post of the booster battery.
Disconnect the positive (+) end of the jumper cable from the positive (+) post of the booster battery.
Disconnect the opposite end of the positive (+) jumper cable from the positive (+) post of the discharged vehicle.
Reinstall the protective cover over the positive (+) post of the discharged vehicle.
If frequent jump starting is required to start your vehicle you should have the battery and charging system tested at an authorized dealer.
Accessories plugged into the vehicle power outlets draw power from the vehicle’s battery, even when not in use (i.e., cellular devices, etc.). Eventually, if plugged in long enough without engine operation, the vehicle’s battery will discharge sufficiently to degrade battery life and/or prevent the engine from starting.
