| 1. |
Remove the air duct (B). |
| 2. |
Disconnect the negative terminal (A) from the battery.
Tightening torque :
3.9 ~ 5.9N.m (0.4 ~ 0.6kgf.m, 2.9 ~ 4.3lb-ft)
|
|
| 3. |
Disconnect the positive terminal (A) from the battery.
Tightening torque :
7.8 ~ 9.8N.m (0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb-ft)
|
|
| 4. |
Remove the battery insulation pad (B). |
| 5. |
Remove the battery mounting bracket (C) by loosening the mounting bolt and then remove the battery (D).
Tightening torque :
9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
|
|
| 6. |
Remove the air cleaner assembly.
|
| 7. |
Disconnect the front connector (A) and then remove the battery tray (B).
Tightening torque :
9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
|
|
| 8. |
Installation is the reverse order of removal.
|
When installing the battery, fix the mounting bracket on the tray correctly. |

Battery Diagnostic Flow
Vehicle parasitic current inspection
| 1. |
Turn the all electric devices OFF, and then turn the ignition switch OFF. |
| 2. |
Close all doors except the engine hood, and then lock all doors.
| (1) |
Disconnect the hood switch connector. |
|
| 3. |
Wait a few minutes until the vehicle’s electrical systems go to sleep mode.
|
For an accurate measurement of a vehicle parasitic current,
all electrical systems should go to sleep mode. (It takes at least one
hour or at most one day.) However, an approximate vehicle parasitic
current can be measured after 10~20 minutes. |
|
| 4. |
Connect an ammeter in series between the battery (-) terminal
and the ground cable, and then disconnect the clamp from the battery
(-) terminal slowly.
|
Be careful that the lead wires of an ammeter do not come off
from the battery (-) terminal and the ground cable to prevent the
battery from being reset. In case the battery is reset, connect the
battery cable again, and then start the engine or turn the ignition
switch ON for more than 10 sec. Repeat the procedure from No. 1.
To prevent the battery from being reset during the inspection,
| 1) |
Connect a jump cable between the battery (-) terminal and the ground cable. |
| 2) |
Disconnect the ground cable from the battery (-) terminal. |
| 3) |
Connect an ammeter between the battery (-) terminal and the ground cable. |
| 4) |
After disconnecting the jump cable, read the current value of the ammeter. |
|
|
| 5. |
Read the current value of the ammeter.
| A. |
If the parasitic current is over the limit value, search for
abnormal circuit by removing a fuse one by one and checking the
parasitic current. |
| B. |
Reconnect the suspected parasitic current draw circuit fuse
only and search for suspected unit by removing a component connected
with the circuit one by one until the parasitic draw drops below limit
value. |
Limit value (after 10~20 min.) : Below 50mA
|
|
| 1. |
Make sure the ignition switch and all accessories are in the OFF position. |
| 2. |
Disconnect the battery cables (negative first). |
| 3. |
Remove the battery from the vehicle.
|
Care should be taken in the event the battery case is cracked or leaking, to protect your skin from the electrolyte.
Heavy rubber gloves (not the household type) should be worn when removing the battery. |
|
| 4. |
Inspect the battery tray for damage caused by the loss of
electrolyte. If acid damage is present, it will be necessary to clean
the area with a solution of clean warm water and baking soda. Scrub the
area with a stiff brush and wipe off with a cloth moistened with baking
soda and water. |
| 5. |
Clean the top of the battery with the same solution as described above. |
| 6. |
Inspect the battery case and cover for cracks. If cracks are present, the battery must be replaced. |
| 7. |
Clean the battery posts with a suitable battery post tool. |
| 8. |
Clean the inside surface of the terminal clamps with a
suitable battery cleaning tool. Replace damaged or frayed cables and
broken terminal clamps. |
| 9. |
Install the battery in the vehicle. |
| 10. |
Connect the cable terminals to the battery post, making sure tops of the terminals are flush with the tops of the posts. |
| 11. |
Tighten the terminal nuts securely. |
| 12. |
Coat all connections with light mineral grease after tightening.
|
When batteries are being charged, an explosive gas forms
beneath the cover of each cell. Do not smoke near batteries being
charged or which have recently been charged. Do not break live circuit
at the terminals of batteries being charged.
A spark will occur when the circuit is broken. Keep open flames away from battery. |
