For safety and security
There is an air intake vent beside the
rear left seat for the purpose of
cooling the hybrid battery (traction
battery). If the vent becomes
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
When a certain level of impact is detected by the impact sensor, the emer-
gency shut off system blocks off the high voltage current and stops the fuel
pump to minimize the risk of electr ocution and fuel leakage. If the emer-
gency shut off system activates, your ve hicle 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 instruc-
tions.

7-2. Steps to take in an emergency
Fuel pump shut off system (gasoline vehicles)
Follow the procedure below to restart the engine after the system is acti-
vated.
Turn the “START STOP ENGINE” switch to ACCESSORY mode or
turn it off.
Restart the engine.
To minimize the risk of fuel leakage when the engine stalls or when an
airbag inflates upon collision, the fuel pump shut off system stops the
supply of fuel to the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto th e ground, the fuel system has been damaged
and is in need of repair. Do not restart the engine.

Vehicle specifications
Fuel information
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that only
accommodates the special nozzle on unleaded fuel pumps.
■Gasoline quality
In very few cases, driveability problems ma y be caused by the brand of gasoline you
are using. If driveability problems persist, try changing the brand of gasoline. If this
does not correct the problem, consult your Lexus dealer.
■Gasoline quality standards
●Automotive manufacturers in the U.S.A., Europe and Japan have developed a
specification for fuel quality called the World-Wide Fuel Charter (WWFC), which
is expected to be applied worldwide.
●The WWFC consists of four categories that are based on required emission levels.
In the U.S., category 4 has been adopted.
●The WWFC improves air quality by lowering emissions in vehicle fleets, and
improves customer satisfaction through better performance.
You must only use unleaded gasoline in your vehicle.
Select octane rating 87 (Research Octane Number 91) or higher. Use
of unleaded gasoline with an octane rating lower than 87 may result in
engine knocking. Persistent knockin g can lead to engine damage.
At minimum, the gasoline you us e should meet the specifications of
ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.

8-1. Specifications
■Recommendation of the use of gasoline containing detergent additives
●Lexus recommends the use of gasoline that contains detergent additives to avoid
the build-up of engine deposits.
●All gasoline sold in the U.S.A. contains minimum detergent additives to clean and/
or keep clean intake systems, per EPA’ s lowest additives concentration program.
●Lexus strongly recommends the use of Top Tire Detergent Gasoline. For more
information on Top Tire Detergent Gasoline and a list of marketers, please go to the
official website www.toptiregas.com
.
■Recommendation of the use of cleaner burning gasoline
Cleaner burning gasoline, including reformul ated gasoline that contains oxygenates
such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many areas.
Lexus recommends the use of cleaner burn ing gasoline and appropriately blended
reformulated gasoline. These types of ga soline provide excellent vehicle perfor-
mance, reduce vehicle emissions and improve air quality.
■Non-recommendation of the use of blended gasoline
●If you use gasohol in your vehicle, be sure that it has an octane rating no lower than
87.
●Lexus does not recommend the use of gasoline containing methanol.
●Use only gasoline containing a maximum of
10% ethanol.
DO NOT use any flex-fuel or gasoline that
could contain more than 10% ethanol,
including from any pump labeled E15, E30,
E50, E85 (which are only some examples
of fuel containing mo re than 10% ethanol).DO NOT use gasoline con-
taining more than 10% ethanol.
(15% ethanol)
(50% ethanol)
(85% ethanol)
