Advanced Parking Guidance System
2. GENERAL PRECAUTION
(a) While using the battery during inspection, do not bring the positive (+) and negative (-) tester probes too
close to each other as a short circuit may occur.
3. PRECAUTIONS WHEN USING TECHSTREAM
(a) When using the Techstream with the power switch off to troubleshoot:
Connect the Techstream to the vehicle, and turn a courtesy light switch on and off at 1.5-second intervals until
communication between the Techstream and vehicle begins.
(b) After all DTCs are cleared, check if the trouble occurs again 6 seconds after the power switch is turned on
(IG).
4. OPERATION PRECAUTIONS
(a) The solar ventilation system operates using electrical power generated by the moon roof glass assembly
(solar panel). Therefore, the solar ventilation system stops operating when the amount of electricity generated
by the moon roof glass assembly (solar panel) becomes insufficient.
HINT:
If the solar ventilation system stops operating due to the moon roof glass assembly (solar panel) generating an
insufficient amount of electricity, the solar ventilation system will resume operating after output from the moon
roof glass assembly (solar panel) has recovered.

System Name
(b) The solar ventilation system may degrade the air quality in the cabin
or lower air conditioning efficiency depending on the usage environment.
When ventilation is not necessary, turn the solar ventilation switch off.
Depending on the usage environment, exhaust emissions from
other vehicles or polluted outside air may enter in the cabin.
Depending on the strength of the sunlight when the outside
temperature is low, the cabin temperature may become low
because of the cool air drawn into the cabin due to solar
ventilation system operation.
