2016 LEXUS RX450H warning

82 1-3. Hybrid system
RX450h_U_OM0E013U ■
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 3 8 )
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 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.
WA R N I N G ■
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 under the rear seat. The service
plug is used only when the vehicle is serviced
and is subject to high voltage.
