warning Lexus GS300h 2017 Owner's Guide

821-2. Hybrid system
GS450h_300h_OM_OM30F92E_(EE)
■If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
connected
The hybrid system may not start. In this case, try to start the system again. If the “READY”
indicator does not come on, contact any authorized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light ( P. 462)
go off. If there is only a small amount of fuel, the hybrid sys tem may not be able to start.
(The standard amount of fuel is about 9.9 L [2 .6 gal., 2.2 Imp.gal.], when the vehicle is on
a level surface. This value may vary when the vehicle is on a slope. Add extra fuel when
the vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid ve hicles incorporate electromagnetic shield-
ing, and therefore emit approximately the same amount of electromagnetic waves as
conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference in some third party-produced radio parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a lim ited service life. The lifespan of the hybrid
battery (traction battery) can change in accordance with driving style and driving condi-
tions.
■Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100 (Battery
electric vehicle safety).
WARNING
■High voltage precautions
This 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 hi gh temperature, and always obey the warn-
ing 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 ser-
viced and is subject to high voltage.

For safety and security
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 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 con-
nected to the electric motor (traction motor) are on the ground when towing, the
motor may continue to generate electricity. This may cause a fire. ( P. 454)
●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.

WARNING
■Hybrid battery (traction battery)
●Never resell, hand over or modify the hy brid battery. To prevent accidents, hybrid
batteries that have been removed from a disposed vehicle are collected through any
authorized Lexus retailer or Lexus authoriz ed repairer, or any reliable repairer. Do
not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting in death
or serious injury:

WARNING
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, the information display monitor may respond
slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear number
appearing on the display. This lag could cau se the driver to downshift again, causing
rapid and excessive engine braking and po ssibly an accident resulting in death or
injury.
NOTICE
■To prevent damage to the hybrid system and its components
●While the tachometer is displayed, do not let the indicator needle of the tachometer
enter the red zone, which indicates the maximum engine speed.
●The engine may be overheating if the engine coolant temperature gauge is in the red
zone (H). In this case, immediately stop the vehicle in a safe place, and check the
engine after it has cooled completely. ( P. 535)
