1-1. Hybrid system
Hybrid battery air vent
There is an air intake vent on the
side of the rear left seatback for
the purpose of cooling the hybrid
battery (traction battery). If the
vent become blocked, the hybrid
battery may overheat, leading to a
reduction in hybrid battery output.
Emergency shut off system
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks off the high voltage current and stops
the fuel pump to minimize the risk of electrocution and fuel leakage. If the
emergency shut off system activates, yo ur vehicle will not restart. To
restart the hybrid system, contact your Lexus dealer.
Hybrid warning message
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.

Before driving
■If a warning light comes on, a warning message is displayed, or the 12-volt battery
is disconnected
The hybrid system may not start. In that case,
try to start the system again. If the
“READY” indicator does not come on, contact your Lexus dealer.
■Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electromag -
netic shielding, and therefore emit appr o
ximately the same amount of electro-
magnetic waves as conventional gasoline powered vehicles or home electronic
appl
iances.
●Your vehicle may cause sound interference in some third party produced radio
parts.
●Consult your Lexus dealer before installing or removing third party-produced
radio parts.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid sy
stem cannot be started, refuel
the vehicle with at least enough gasoline to make the low fuel level warning light
(  P. 4 9 5 ) go off. If there is only a small amount of fuel, the hybrid system may not
be able to start. (The minimum amount of
fuel to add to make the low fuel level
warning light go out is more than 2.6 gal. [1 0 L, 2.1 Imp.gal.], when the vehicle is on a
level surface. This value may vary when the vehicle is on a slope.)
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of the
hybri
d battery (traction battery) can chan ge in accordance with driving style and
driving conditions.
