Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and odorless. Observe the following precautions.Failure to do so may cause exhaust gases enter the vehicle and may lead to an accident
caused by light-headedness, or may lead to death or a serious health hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in the vehicle even when the trunk lid is closed, open the windows and have the vehicle inspected at any authorized Lexus dealer or repairer,or another duly qualified and equipped professional as soon as possible.
■When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the hybrid system.
●Do not leave the vehicle with the hybrid system on for a long time.If such a situation cannot be avoided, park the vehicle in an open space and ensurethat exhaust fumes do not enter the vehicle interior.
●Do not leave the hybrid system operating in an area with snow build-up, or where it is snowing. If snowbanks build up around the vehicle while the hybrid system is operat- ing, exhaust gases may collect and enter the vehicle.
■Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or crack caused by corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehicle
inspected and repaired by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.

Hybrid system precautions
Take care when handling the hybrid system, as it is a high voltage system
(about 650 V at maximum) as well as contains parts that become extremely
hot when the hybrid system is operatin g. Obey the warning labels attached to
the vehicle.

901-2. Hybrid system
RC300h_EE(OM24740E)
There is an air intake vent on the right
side of the rear seat back for the pur-
pose of cooling the hybrid battery
(traction battery). If the vent becomes
blocked, the hybrid battery may over-
heat, leading to a reduction in hybrid
battery output.
When a certain level of impact is detected by the impact sensor, the emergency
shut off system blocks the high voltage current and stops the fuel pump to mini-
mize the risk of electrocution and fuel leakage. If the emergency shut off system
activates, your vehicle will not restart. To restart the hybrid system, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
A message is automatically displayed when a malfunction occurs in the hybrid
system or an improper operation is attempted.
If a warning message is shown on the
multi-information display, read the
message and follow the instructions.

■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 dealer or repairer, or another
duly qualified and equipped professional.
■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. 539) go off. If there is only a small amount of fuel, the hybrid system may not be able to start.(The standard amount of fuel is about 10 L [2.7 gal., 2.2 Imp. gal.] when the vehicle is on a
level surface. This value may vary when the vehi cle 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. Becareful 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 accesshole located under the luggage under tray.
The service plug is used only when the vehicle is serviced and is subject to high voltage.

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.

WARNING
■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 any
authorized Lexus dealer or repairer, or an other duly qualified and equipped profes- sional. Do not dispose of the battery yourself.
Unless the battery is properly collected, the 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 batterymust be disposed of by any authorized Lexu s dealer or repairer, or another duly qual-
ified and equipped professional. If the hybrid battery is not disposed of properly, it may cause electric shock that can result in death or serious injury.
NOTICE
■Hybrid battery (traction battery) air intake vent
●Do not place objects that will block the air intake vent. The hybrid battery (traction
battery) may overheat and be damaged.
●Clean the air intake vent regularly to prevent the hybrid battery (traction battery) from overheating.
●Do not get water or foreign materials in the air intake vent as this may cause a shortcircuit and damage the hybrid battery (traction battery).
●Do not carry large amounts of water such as water cooler bottles in the vehicle. If
water spills onto the hybrid battery (tract ion battery), the battery may be damaged. Have the vehicle inspected by any authorized Lexus dealer or repairer, or anotherduly qualified and equipped professional.
