WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
●Pull your vehicle off the road, shift the shift lever to P, apply the parking brake, and
turn the hybrid system off.
●Do not touch the high voltage parts, cables and 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 flui d 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 immedi ate 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 el ectric fires. Using even a small amount of
water may be dangerous.
●If your vehicle needs to be towed, do so wi th all four 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 elec tricity. This may cause a fire. (P. 654)
●Carefully inspect the ground under the vehicl e. 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.
