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.

There is an air intake vent on the right
side of the rear seatback 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 detect ed 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 retailer or Lexus author ized repairer, or any reliable repairer.
A message is automatically displayed wh en 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 au thorized 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. 577)
go off. If there is only a smal l 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 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 li mited service life. The lifespan of the hybrid
battery (traction battery) can change in acco rdance with driving style and driving condi-
tions.
■Declaration of conformity
This model conforms to hydrogen emission s according to regulation ECE100 (Battery
electric vehicle safety).

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 retailer or Lexus authoriz ed repairer, or any reliable repairer. 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 disposed 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 any authorized Lexu s retailer or Lexus authorized repairer, or
any reliable repairer. 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 short
circuit 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 (traction battery), the battery may be damaged.
Have the vehicle inspected by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.

■Tilt sensor detection considerations
The sensor may trigger the alar m in the following situations:
●The vehicle is transported by a ferry, trailer, train, etc.
●The vehicle is parked in a parking garage.
●The vehicle is inside a car wash that moves the vehicle.
●Any of the tires loses air pressure.
●The vehicle is jacked up.
●An earthquake occurs or the road caves in.
NOTICE
■To ensure the intrusion sensor function correctly
●Installing accessories other than genuine Lexus parts or leaving objects between the driver’s seat and front passenger’s seat may reduce the detection performance.
●To ensure that the sensors operate properly,
do not touch or cover them.
●Do not spray air fresheners or other products
directly into the sensor holes.

WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on when you start the hybrid system, this could mean that these systems are not available to help
protect you in an accident, which could result in death or serious injury. Have the vehi-
cle inspected by any authorized Lexus retailer or Lexus authorized repairer, or any reli- able repairer immediat ely if this occurs.
