If your child restraint system is not
equipped with a lock-off (a seat
belt locking feature), secure the
child restraint system using a
locking clip.
After installing the child restraint system, rock it back and forth to ensure
that it is installed securely.
◆Removing a child restraint system installed with a seat belt
Press the buckle release button and
fully retract the seat belt.
When releasing the buckle, the child restraint system may spring up due tothe rebound of the seat cushion.
Release the buckle while holding down the child restraint system.
Since the seat belt automatically
reels itself, slowly return it to the stowing position.

vide a locking clip, you can purchase the following item from any authorized Lexus dealer or repairer, or another duly qualified and equipped professional: Locking clip for child restrain t system (Part No. 73119-22010)

WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
●Pull your vehicle off the road, apply the parking brake, shift the shift lever to P, and
turn the hybrid system off.
●Do not touch the high voltage parts, cables or connectors.
●If electric wires are exposed inside or ou tside your vehicle, an electric shock may
occur. Never touch exposed electric wires.
●If a fluid leak occurs, do not touch the fluid as it may be strong alkaline electrolyte from the hybrid battery (traction battery). If it comes into contact with your skin or
eyes, wash it off immediately with a large amount of water or, if possible, boric acid solution. Seek immediate medical attention.
●If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never use a
fire extinguisher that is not meant for electric fires. Using even a small amount of water may be dangerous.
●If your vehicle needs to be towed, do so with front wheels raised. If the wheels con-
nected to the electric motor (traction mot or) are on the ground when towing, the motor may continue to generate electricity. This may cause a fire. ( P. 530)
●Carefully inspect the ground under the vehicle. If you find that liquid has leaked onto
the ground, the fuel system may have been damaged. Leave the vehicle as soon as possible.
