Jump starting procedure
1. Make sure the booster battery is
12-volt and that its negative termi‐
nal is grounded.
2. If the booster battery is in another
vehicle, do not allow the vehicles
come in contact.
3. Turn off all unnecessary electrical
loads.
4. Connect the jumper cables in the
exact sequence shown in the illus‐
tration. First connect one end of a
jumper cable to the positive termi‐
nal of the discharged battery (1),
then connect the other end to the
positive terminal on the booster
battery (2).
Proceed to connect one end of the
other jumper cable to the negative
terminal of the booster battery (3),
then the other end to a solid, sta‐
tionary, metallic point (for example,
the engine lifting bracket) away
from the battery (4). Do not con‐
nect it to or near any part that
moves when the engine is cranked.
Do not allow the jumper cables to
contact anything except the correct
battery terminals or the correct
ground. Do not lean over the bat‐
tery when making connections.
CAUTION
n
Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative ter‐
minal of the discharged battery. This
can cause the discharged battery to
overheat and crack, releasing bat‐
tery acid.
5. Start the engine of the vehicle with
the booster battery and let it run
at 2,000 rpm, then start the engine
of the vehicle with the discharged
battery.
If the cause of your battery discharging
is not apparent, we recommend that
the system be checked by an author‐
ized Kia dealer.
Push-starting
Your manual transaxle-equipped vehi‐
cle should not be push-started because
it might damage the emission control
system.
Vehicles equipped with automatic
transaxle/dual clutch transmission can‐
not be push-started.
Follow the directions for jump-starting
in Jump starting on page 7-05.
WARNING
Never tow a vehicle to start it be‐
cause the sudden surge forward
when the engine starts could cause
a collision with the tow vehicle.
