NX300h_OM_USA_OM78082U
The cooling air intake and discharge
vents for the hybrid battery (traction
battery) are located under the rear
seats and between the rear seats and
deck board, respectively. If the air
intake vents are blocked, it could lead
to a reduction in hybrid battery (trac-
tion battery) output.
The hybrid battery (traction battery)
output will not be reduced, even if the
space between the upper part of the air
discharge vents on the back of the rear
seat and deck board is blocked with lug-
gage, etc.
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 your
Lexus dealer.
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 your Lexus dealer.
■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. 5 6 7 )
go off. If there is only a small amount of fu el, the hybrid system may not be able to start.
(The standard amount of fuel is about 2.7 gal. [10.1 L, 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 vehicl es 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 limited service life. The lifespan of the hybrid
battery (traction battery) can change in accordance with driving style and driving condi-
tions.

■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 star ting 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 underneath the rear seats. The
service plug is used only when the vehicle is
serviced and is subject to high voltage.

*1: These lights turn on when the power switch is turned to ON mode to indicate that a system check is being performed. They will turn off after the hybrid system is on, or
after a few seconds. There may be a malfunction in a system if the lights do not turn on,
or turn off. Have the vehicle inspected by your Lexus dealer.

*5: In order to confirm operation, the BSM outside rear view mirror indicators illuminate in the following situations:
• When the power switch is turned to ON mode while the BSM main switch is set to
ON.
• When the BSM main switch is set to ON while the power switch is in ON mode.
If the system is functioning correctly, the BSM outside rear view mirror indicators will
turn off after a few seconds.
If the BSM outside rear view mirror indica tors do not illuminate or do not turn off,
there may be a malfunction in the system.
If this occurs, have the vehicle inspected by your Lexus dealer.
*6: This light illuminates on the outside rear view mirrors.
*7: This light illuminates on the center panel.

■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS airbag 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 a ccident, which could result in death or serious injury. Have
the vehicle inspected by your Lexus dealer immediately if this occurs.
