■Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
●Stop the vehicle in a safe place to prevent subsequent accidents. While depressing
the brake pedal, apply the parking brake and shift the shift position to P to stop the
hybrid system. Then, slowly release the brake pedal.
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside 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 motor) are on the ground when towing, the
motor may continue to generate electricit y. This may cause an electricity leakage
leading to a fire. ( →P. 5 2 2 )
●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.
■Hybrid battery (traction battery)
●Never resell, hand over or modify the hybrid battery. To prevent accidents, hybrid
batteries that have been removed from a disposed vehicle are collected through
Lexus dealer. Do not dispose of the battery yourself.
Unless the battery is properly collected, th e following may occur, resulting in death
or serious injury:
• The hybrid battery may be illegally dispos ed of or dumped, and it is hazardous to
the environment or someone may touch a high voltage part, resulting in an electric
shock.
• The hybrid battery is intended to be used exclusively with your hybrid vehicle. If the hybrid battery is used outside of your vehicle or modified in any way, accidents
such as electric shock, heat generation , smoke generation, an explosion and elec-
trolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident is
extremely high because the person receiving the vehicle may not be aware of these
dangers.
●If your vehicle is disposed of without the hybrid battery having been removed, there is
a danger of serious electric shock if high voltage parts, cables and their connectors
are touched. In the event that your vehicle must be disposed of, the hybrid battery
must be disposed of by your Lexus dealer or a qualified service shop. If the hybrid bat-
tery is not disposed of properly, it may cause electric shock that can result in death or
serious injury.

Observe the following precautions.
Failure to do so may result in death or serious injury.
■Before driving
●Make sure that the back door is fully closed. If the back door is not fully closed, it may
open unexpectedly while driving and hit near-by objects or luggage in the luggage
compartment may be thrown out, causing an accident.
●Do not allow children to play in the luggage compartment.
If a child is accidentally locked in the luggage compartment, they could have heat
exhaustion or other injuries.
●Do not allow a child to open or close the back door.
Doing so may cause the back door to open unexpectedly, or cause the child’s hands,
head, or neck to be caught by the closing back door.
■Important points while driving
●Keep the back door closed while driving.
If the back door is left open, it may hit near-by objects or luggage in the luggage com-
partment may be thrown out, causing an accident.
●Never let anyone sit in the luggage compartment. In the event of sudden braking,
sudden swerving or a collision, they are susceptible to death or serious injury.
■Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death or serious
injury.
●Remove any heavy loads, such as snow and ice, from the back door before opening it.
Failure to do so may cause the back door to suddenly shut again after it is opened.
●When opening or clos ing the back door, thoroughly check to make sure the sur-
rounding area is safe.
●If anyone is in the vicinity, make sure they are safe and let them know that the back
door is about to open or close.
●Use caution when opening or closing the ba ck door in windy weather as it may move
abruptly in strong wind.
●The back door may suddenly shut if it is not
opened fully. It is more difficult to open or
close the back door on an incline than on a
level surface, so beware of the back door
unexpectedly opening or closing by itself.
Make sure that the back door is fully open and
secure before using the luggage compart-
ment.
