1-1. Hybrid system

Before driving
Hybrid battery air ventThere 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, your 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 impr oper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions.
(P. 507)

1-1. Hybrid system
■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 theref ore emit approximately the same amount of electro-
magnetic waves as conventional gasoline powered vehicles or home electronic
appliances.
●Your vehicle may cause sound interference in some third party-produced radio
parts.
■Running out of fuel
When the vehicle has run out of fuel and th e hybrid system cannot be started, refuel
the vehicle with at least enough gasoline to make the low fuel level warning light
(  P. 501) 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 about 2.6 gal. [10 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
hybrid battery (traction battery) can chan ge in accordance with driving style and
driving conditions.

■Alarms and warning indicators
A combination of exterior and interior alarms as well as warning messages shown
on the multi-information display is used to prevent theft of the vehicle and accidents
resulting from erroneous operation. Take appropriate measures in response to any
warning message on the multi-information display. ( P. 5 0 7 )
The following table describes circumstances and correction procedures when only
alarms are sounded.
■Security feature
If a door is not opened within approx imately 60 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again.
■Battery-saving function
The battery-saving function will be activa ted in order to prevent the electronic key
battery and the 12-volt battery from bein g discharged while the vehicle is not in
operation for a long time.
●In the following situations, the smart access system with push-button start may
take some time to unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of the
outside of the vehicle for 10 minutes or longer.
