2021 RAM 1500 Owners Manual - JUMP STARTING



JUMP STARTING

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.

PREPARATIONS FOR JUMP START

The battery in your vehicle is located in the front of the engine compartment, behind the left headlight assembly.

NOTE:

Battery Location

NOTE:

When using a portable battery booster pack, follow the manufacturer's operating instruc- tions and precautions.

The positive battery post may be covered with a protective cap. Lift up on the cap to gain access to the positive battery post. Do not jump off fuses. Only jump directly off positive post which has a positive (+) symbol on or around the post.

JUMP STARTING PROCEDURE

See below steps to prepare for jump starting:

    Apply the parking brake, shift the automatic transmission into PARK and turn the ignition OFF.
    Turn off the heater, radio, and all electrical accessories.
    Pull upward and remove the protective cover over the remote positive (+) battery post.
    If using another vehicle to jump start the battery, park the vehicle within the jumper cables’ reach, apply the parking brake and make sure the ignition is OFF.

    Connect the positive (+) end of the jumper cable to the positive (+) post of the discharged vehicle.

Do not jump off fuses. Only jump directly off positive post.

    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.

    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.

    Once the engine is started, follow the disconnection procedure below.
    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 vehicle with the discharged battery.

If frequent jump starting is required to start your vehicle you should have the battery and charging system inspected at an authorized dealer.
