531-2. Child safety
LS500h_OM_(U)_1809

For safety and security
■Child restraint LATCH anchors
LATCH anchors are provided for the 
outboard rear seat. (Buttons displaying 
the location of the anchors are 
attached to the seats.)
■Installation with LATCH system
Install the child restraint system in 
WARNING
●Do not allow children to play with the 
seat belt. If the seat belt becomes 
twisted around a child’s neck, it may 
lead to choking or other serious inju-
ries that could result in death.
If this occurs and the buckle cannot be 
unfastened, scissors should be used to 
cut the belt.
●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.
●When a booster seat  is installed, 
always ensure that th e 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 child’s 
shoulder.
●Follow all installation instructions pro-
vided by the child restraint system 
manufacturer.
●When securing some  types of child 
restraint systems in rear seats, it may 
not be possible to properly use the 
seat belts in position s next to the child 
restraint without inte rfering with it or 
affecting seat belt effectiveness. Be 
sure your seat belt fits snugly across 
your shoulder and low on your hips. If it 
does not, or if it interferes with the 
child restraint, move to a different posi-
tion. Failure to do so may result in 
death or serious injury.
●When installing a child restraint system 
in the rear center se at, adjust both seat 
cushions to the same position and 
align both seatbacks at the same 
angle. Otherwise,  the child restraint 
system cannot be securely restrained 
and this may cause death or serious 
injuries in the event  of sudden braking, 
sudden swerving or an accident.
■When installing a booster seat
To prevent the belt from going into ALR 
lock mode, do not fully extend the shoul-
der belt. ALR mode causes the belt to 
tighten only. This could cause injury or 
discomfort to the child. ( P.26)
■Do not use a seat belt extender
If a seat belt extender is used when 
installing a child restra int system, the seat 
belt will not securely hold the child 
restraint system, which could cause 
death or serious injury to the child or 
other passengers in the event of sudden 
braking, sudden swerving or an accident.

691-4. Hybrid system
LS500h_OM_(U)_1809

For safety and security
There are air intake vents on each side 
of the rear seatback with the purpose 
of cooling the hybrid battery (traction 
battery). If the vents become blocked, 
hybrid battery output may be reduced. 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 minimize the risk of electrocu-
tion and fuel leakage. If the emergency 
shut off system activates, your vehicle 
will not restart. To restart the hybrid 
system, contact your Lexus dealer.
A message is automatically displayed 
when a malfunction occurs in the 
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the 
multi-information display, read the 
message and follow the instructions.
■If a warning light comes on, a warning 
message is displayed, or the 12-volt bat-
tery is disconnected
The hybrid system may not start. In this 
case, try to start the system again. If the 
“READY” indicator does not come on, con-
Hybrid battery (traction bat-
tery) air intake vents
NOTICE
■Hybrid battery (traction battery) air 
intake vents
●Make sure not to block the air intake 
vent with anything, such as a seat 
cover, plastic cover, or luggage. If the 
vents become blocked, the hybrid bat-
tery (traction battery) input and output 
may be restricted, leading to a reduc-
tion in hybrid battery (traction battery) 
output and a malfunction.
●When dust etc. has accumulated in the 
air intake vent, periodically clean it 
with a vacuum cleaner to prevent the 
vent from clogging.
●A filter is installed to the air intake vent. 
When the filter remains noticeably 
dirty even after cleaning the air intake 
vent, filter cleaning or replacement is 
recommended. When cleaning or 
replacing the filter, contact your Lexus 
dealer.
Refer to P.372 for details on how to 
clean the filters.
●Do not get water or foreign materials 
in the air intake vent s as this may cause 
a short circuit and damage the hybrid 
battery (traction battery).
