WARNING
■When installing a child restraint system
●If child restraint system regulations exist in the country where you reside, please con-
tact any authorized Lexus retailer or Le xus authorized repairer, or any reliable
repairer for the child rest raint system installation.
●When a junior seat is installed, always en sure that the shoulder belt is positioned
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 ch ild’s shoulder. Failing to do so may result in
death or serious injury in the event of su dden braking, sudden swerving or an acci-
dent.
●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 se curely attached, or it may cause death or serious injury to
the child or other passengers in the event of sudden braking, sudden swerving or an
accident.

For safety and security
There are air intake vents on the both
sides of the rear seatback for the pur-
pose of cooling the hybrid battery
(traction battery). If the vents become
blocked, the hybrid battery may over-
heat, leading to a reduction in hybrid
battery output.
When a certain level of impact is detected by the impact sensor, the emergency
shut off system blocks the high voltage current and stops the fuel pump to mini-
mize the risk of electrocution and fuel leakage. If the emergency shut off system
activates, your vehicle will not restart. To restart the hybrid system, contact any
authorized Lexus retailer or Lexus authorized repairer, or any reliable repa irer.
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 instructions. (  P. 466)
