High Voltage Precautions; Road Accident Cautions - Lexus GS450h Owner's Manual

CAUTION

High voltage precautions

■
The vehicle has high voltage DC and AC systems as well as a 12-volt system. DC
and AC high voltage is very dangerous and can cause severe burns and electric
shock that may result in death or serious injury.
Never touch, disassemble, remove or replace the high voltage parts, cables or
●
their connectors.
The hybrid system will become hot after starting as the system uses high voltage.
●
Be careful of both the high voltage and the high temperature, and always obey
the caution labels attached to the vehicle.
Never try to open the service plug access
●
hole located behind the rear seats. The ser-
vice plug is used only when the vehicle is
serviced and is subject to high voltage.

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 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 rear wheels raised. If the wheels
●
connected to the electric motor (traction motor) are on the ground when towing,
the motor may continue to generate electricity. This may cause an electricity
leakage leading to a fire. (P. 496)
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.
