CAUTION
When installing a child restraint system
If child restraint system regulations exist in the country where you reside,
please contact any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional for the child restraint system installation.
When a junior seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child’s shoulder. The belt should be kept away
from the child’s neck, but not so that it could fall off the child’s shoulder. Fail-
ing to do so may result in death or serious injury in the event of sudden brak-
ing, sudden swerving or an accident.
Ensure that the belt and plate are securely locked and the seat belt is not
twisted.
Shake the child restraint system left and right, and forward and backward to
ensure that it has been securely installed.
After securing a child restraint system, never adjust the seat.
Follow all installation instructions provided by the child restraint system
manufacturer.
To correctly attach a child restraint system to the anchors
When using the lower anchors, be sure that there are no foreign objects around
the anchors and that the seat belt is not caught behind the child restraint system.
Make sure the child restraint system is securely attached, or it may cause death
or serious injury to the child or other passengers in the event of a sudden brak-
ing, sudden swerve or an accident.

841-2. Hybrid system
IS300h_EE(OM53B95E)
There is an air intake vent on the
right side of the rear seatback for
the purpose of cooling the hybrid
battery (traction battery). If the vent
becomes blocked, the hybrid battery
may overheat, leading to a reduc-
tion in hybrid battery output.
When a certain level of impact is detected by the impact sensor, the emer-
gency shut off system blocks the high voltage current and stops the fuel
pump to minimize the risk of electrocution and fuel leakage. If the emer-
gency shut off system activates, your vehicle will not restart. To restart
the hybrid system, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
A message is automatically displayed when a malfunction occurs in the
hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the instruc-
tions.
