Kia EV9 2024 - Starting the vehicle

What to do in an emergency
Starting the vehicle
Precautions
WARNING
• Keep all flames or sparks away from the battery. The battery produces hydrogen
gas which may explode if exposed to flame or sparks. If these instructions are not
followed exactly, serious personal injury and damage to the vehicle may occur! If
you are not sure how to follow this procedure, seek qualified assistance. Automobile
batteries contain sulfuric acid. This is poisonous and highly corrosive. When jump
starting, wear protective glasses and be careful not to get acid on yourself, your
clothing or on the vehicle.
• Do not attempt to jump start the vehicle if the discharged battery is frozen or if the
electrolyte level is low; the battery may rupture or explode.
• Do not allow the (+) and (-) jumper cables to touch. It may cause sparks.
• Never attempt to check the electrolyte level of the battery as this may cause the
battery to rupture or explode causing serious injury.
• The battery may rupture or explode when you jump start with a low or frozen bat
tery.
• The electrical starting system works with high voltage. NEVER touch these compo
nents with the READY indicator ON or when the EV button is in the ON position.
CAUTION
Use only a 12-volt jumper system. You can damage other electrical parts beyond re
pair by use of a 24- volt power supply (either two 12-volt batteries in series or a 24-
volt motor generator set).
NOTE
Do not connect the jumper cable from the negative terminal of the booster battery to
the negative terminal of the discharged battery. This can cause the discharged bat
tery to overheat and crack, releasing battery acid. Make sure to connect one end of
the jumper cable to the negative terminal of the booster battery, and the other end to
a metallic point, far away from the battery.
