RX450h_RX450hL _U_OM48F85UThe installation of a mobile two-way radio system in your vehicle could affect electronic
systems such as: ●
Hybrid system ●
Multiport fuel injection system/seque ntial multiport fuel injection system●
Lexus Safety System+ ●
Anti-lock brake system ●
Vehicle dynamics integrated management ●
SRS airbag system ●
Seat belt pretensioner system
Be sure to check with your Lexus dealer for precautionary measures or special instruc-
tions regarding installation of a mobile two-way radio system.
High voltage parts and cables on the hybrid vehicles emit approximately the same
amount of electromagnetic waves as the co nventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the rece ption of the mobile two-way radio.Installation of a mobile two-way radio system

RX450h_RX450hL _U_OM48F85U■
If the SRS airbags deploy (inflate) ●
Slight abrasions, burns, brui sing etc., may be sustained from SRS airbags, due to the
extremely high speed deployment (inflation) by hot gases. ●
A loud noise and white powder will be emitted. ●
Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as the
front seats, parts of the front and rear pillars, and roof side rails, may be hot for several
minutes. The airbag itself may also be hot. ●
The windshield may crack. ●
For Lexus Enform Safety Connect subscribers, if any of the following situations occur,
the system is designed to send an emerge ncy call to the response center, notifying
them of the vehicle’s location (without needing to push the “SOS” button) and an agent
will attempt to speak with the occupants to ascertain the level of emergency and assis-
tance required. If the occupants are unable to communicate, the agent automatically
treats the call as an emergency and helps to dispatch the necessary emergency ser-
vices. ( → P. 571)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.WARNING ■
Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer. The SRS airb ags may malfunction or deploy (inflate)
accidentally, causing death or serious injury. ●
Installation, removal, disassembly and repair of the SRS airbags ●
Repairs, modifications, removal or replacement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, side and rear pillars, roof side rails,
front door panels, front door trims, or front door speakers ●
Modifications to the front door panel (such as making a hole in it) ●
Repairs or modifications of the front fend er, front bumper, or side of the occupant
compartment ●
Installation of a grille guard (bull bars, ka ngaroo bar, etc.), snow plows, winches or
roof luggage carrier ●
Modifications to the vehicle’s suspension system ●
Installation of electronic devices such as mobile two-way radios and CD players●
Modifications to your vehicle for a person with a physical disability

80 1-3. Hybrid system
RX450h_RX450hL _U_OM48F85U■
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. 662)
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 2.9 gal. [11.0 L, 2.4 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.
WARNING ■
High voltage precautions
This vehicle has high voltage DC and AC sy stems 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 warn-
ing labels attached to the vehicle.●
Never try to open the service plug access
hole located under the rear seat. The service
plug is used only when the vehicle is serviced
and is subject to high voltage.

Tire pressure ●
It may take a few minutes to display the tire inflation pressure after the power switch is
turned to ON mode. It may also take a few minutes to display the tire inflation pressure
after inflation pressure has been adjusted.●
“---” may be displayed if the tire position information cannot be determined due to
unfavorable radio wave conditions. ●
Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge. ■
Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is characteristic
of liquid crystal displays, and there is no problem continuing to use the display.■
Customization
Some functions can be customized. ( → P. 108, 736)
WARNING ■
Caution for use while driving ●
When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle. ●
Do not look continuously at the multi-info rmation display while dr iving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle. ■
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, th e information display monitor may respond
slowly, and display changes may be delayed.
For example, there is a lag between the dr iver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, causing
rapid and excessive engine braking and possibly an accident resulting in death or
injury. ■
Cautions during setting up the display
As the hybrid system needs to be operating during setting up the display, ensure that
the vehicle is parked in a place with adequa te ventilation. In a closed area such as a
garage, exhaust gases including harmful carbon monoxide (CO) may collect and enter
the vehicle. This may lead to dea th or a serious health hazard.
NOTICE ■
While setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid syst em is operating while
setting up the display features.
