The Kia EV6 may fail to start if the 12-volt battery charge is insufficient or if a related electrical issue is present.
Check the battery condition by performing the following steps:
Verify that the shifter dial is positioned in P (Park). The Kia EV6 can only be started when the transmission selector is in the Park position.
Inspect the 12-volt battery terminals and connections to ensure they are clean, secure, and free of corrosion.
Confirm that no warning messages related to the battery or electrical system are displayed on the instrument cluster.
WARNING
Never attempt to push-start or tow-start the Kia EV6. Doing so may cause severe damage to the electric drive system and could result in injury to the driver, passengers, or nearby individuals.
Jump Starting (12V Battery)
When performing a jump-start procedure on the Kia EV6, always connect the jumper cables in the exact numerical sequence shown in the illustration below and disconnect them in the reverse order after the procedure is complete.

Jump-starting the Kia EV6 can be hazardous if the procedure is not followed correctly. Incorrect cable connections may cause personal injury, battery damage, electrical system damage, or fire. If you are uncertain about any step, seek assistance from a qualified technician, roadside assistance provider, or authorized Kia dealer.
WARNING
Battery Inspection
Never attempt to inspect or check the electrolyte level of the battery. Doing so may cause the battery to rupture, leak hazardous materials, or explode unexpectedly.
WARNING
Frozen Batteries
Do not attempt to jump-start the Kia EV6 if the discharged battery is frozen. A frozen battery may crack, rupture, or explode during charging or jump-starting.
WARNING
Electrolyte Safety
Do not charge or discharge the battery in an improper manner. Incorrect handling may result in system malfunction, electric shock, burns, or fire.
Prevent physical damage to the battery. Dropping, deforming, puncturing, striking, crushing, or exposing the battery to sharp objects may cause electrolyte leakage, overheating, or fire.
If the battery becomes damaged, it may release electrolyte or generate flammable gases. Contact an authorized Kia dealer immediately for professional inspection.
If electrolyte comes into contact with your eyes, skin, or clothing, flush the affected area immediately with clean water and seek medical attention without delay.
Never place the battery near open flames, sparks, welding equipment, or sources of intense heat.
Keep the battery out of the reach of children and animals.
Protect the battery from moisture, water, and spilled liquids. Do not touch or operate battery components if liquid contamination is present.
WARNING
Battery Cables
Never connect the negative jumper cable directly between the negative terminal of the booster battery and the negative terminal of the discharged battery. This may cause excessive heat buildup, battery damage, cracking, or explosion.
Always connect the negative jumper cable from the booster battery to a suitable chassis ground point within the motor compartment of the Kia EV6.
WARNING
Sulfuric Acid Hazard
Automotive batteries contain sulfuric acid, a highly corrosive and poisonous substance. When jump-starting the Kia EV6, avoid contact with battery acid. If contact occurs, immediately flush the affected area with large amounts of clean water and seek medical assistance.
WARNING
Battery Safety
Keep all flames, sparks, cigarettes, and ignition sources away from the battery. Hydrogen gas generated by batteries is extremely flammable and may explode if exposed to an ignition source.
Jump Starting Procedure
Verify that the booster battery is a 12-volt battery and that its negative terminal is properly grounded.
If the booster battery is installed in another vehicle, ensure that the two vehicles do not touch each other at any point.
Turn OFF all unnecessary electrical accessories, including lights, climate-control systems, audio equipment, and charging devices.
Connect the jumper cables exactly as illustrated. First, connect one end of the positive jumper cable to the positive terminal of the discharged battery (1), then connect the other end to the positive terminal of the booster battery (2).
Next, connect one end of the second jumper cable to the negative terminal of the booster battery (3), then attach the remaining end to a solid, stationary metal grounding point located away from the battery (4).
Ensure that the jumper cables do not contact moving parts, painted surfaces, or incorrect terminals. Avoid leaning directly over the battery while making connections.
Start the vehicle containing the booster battery and allow it to run for several minutes. Then attempt to start the Kia EV6 using the discharged battery.
After the Kia EV6 starts successfully, carefully disconnect the jumper cables in the reverse order of installation.
If the reason for the battery discharge is unknown or if repeated jump-starting becomes necessary, have the Kia EV6 inspected by an authorized Kia dealer as soon as possible.
NOTE
Always connect one end of the negative jumper cable to the negative terminal of the booster battery and the other end to a grounded metallic point located away from the discharged battery. This reduces the risk of sparks near the battery.
Push Starting
Kia EV6 vehicles equipped with an electric powertrain must never be push-started or roll-started under any circumstances.
WARNING
Tow-Starting Vehicle
Never attempt to tow-start the Kia EV6.
If the vehicle suddenly begins operating during a tow-start attempt, it may surge forward unexpectedly and cause a collision with the towing vehicle, nearby objects, or pedestrians.
