CAUTION:
• Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.
• Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.
• Be careful not to cut your hand on the heat insulator edge.

• If the insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insula-
tor, remove them.
• When installing the insulator avoir large gaps or interference between the insulator and each
exhaust pipe.
• Remove desits from the sealing surface or each connection. Connect them securely to avoid gas
leakage.
• If it is difficult to install mounting rubber, use mild detergent for smooth installation.
• When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left
directions.
• Temporarily tighten mounting nuts. Check each part for unusual interference, and then tighten them
to the specified torque.

INSPECTION AFTER INSTALLATION
• Make sure clearance between tail tube and rear bumper is even.
• With engine running, check exhaust tube joints for gas leakage and unusual noises.
• Ensure that mounting brackets and mounting rubbers are installed properly and free from undue stress.
Improper installation could result in excessive noise and vibration.

CAUTION:
• Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.
• Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.
• Be careful not to cut your hand on the heat insulator edge.
• Never use silicon-containing products (e.g. oil) to prevent malfunctions such as the interference with
the conduction of electricity and the occurrence of noise in the radio.
• Prevent rust preventives from adhering to the sensor body.
Precautions for Removing Battery Terminal
INFOID:0000000010665050
• When removing the 12V battery terminal, turn OFF the ignition
switch and wait at least 30 seconds.
NOTE:
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption may
occur.
• For vehicles with the 2-batteries, be sure to connect the main bat-
tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be
detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
NOTE:
The removal of 12V battery may cause a DTC detection error.

- Using heated oxygen sensor wrench [SST: KV10114400] (A),
removal heated oxygen sensor 2
.
CAUTION:
Discard any sensor which has been dropped from a height of
more than 0.5 m (19.7 in) onto a hard surface such as a con-
crete floor; use a new one.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
• Always replace gaskets with new ones when reassembling.
• Discard any heated oxygen sensor 2 which has been dropped onto a hard surface such as a con-
crete floor. Use a new one.
• Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxy-
gen sensor thread cleaner [commercial service tool (J-43897-18 or J-43897-12)] and apply anti-seize
lubricant (commercial service tool).
• Never over torque heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sen-
sor 2, resulting in the “MIL” coming on.
• If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat
insulator, remove them.
• When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.
• Remove deposits from the sealing surface of each connection. Connect them securely to avoid gas
leakage.
• Temporarily tighten mounting nuts and bolts. Check each part for unusual interference and mount-
ing rubber interference, and then tighten them to the specified torque.
• When installing each mounting rubber, avoid twisting or unusual extension in up/down, front/rear
and right/left directions.
• Install mounting rubber, refer to the following instructions,
- Install slit of the mounting rubber
is in a horizontal direction.

INSPECTION AFTER INSTALLATION
• Check clearance between tail tube and rear bumper is even.
• With engine running, check exhaust tube joints for gas leakage and unusual noises.
• Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.
