Fuel pump shut off system
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked on to the ground, the fuel system has been damaged
and is in need of repair. Do not restart the engine.
To minimize the risk of fuel leakage when the engine stalls or an airbag
inflates upon collision, the fuel pump shut off system stops supplying fuel to
the engine.
Follow the procedure below to restart the engine after the system is
activated.
Turn the “ENGINE START STOP” switch to the ACCESSORY
mode or OFF.
Restart the engine.

Fuel information
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only
accommodates the special nozzle on unleaded fuel pumps.
■If your engine knocks
●Consult your Lexus dealer.
●You may occasionally notice light knocking for a short time while accelerating
or driving uphill. This is normal and there is no need for concern.
■Gasoline quality
In very few cases, driveability problems may 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.
Your vehicle must use only unleaded gasoline.
Premium unleaded gasoline with an octane rating of 91 (Research Octane
Number 96) or higher required for optimum engine performance. If 91
octane cannot be obtained, you may use unleaded gasoline with an octane
rating as low as 87 (Research Octane Number 91). Use of unleaded gaso-
line with an octane rating lower than 91 may result in engine knocking and
significantly reduced performance. Persistent knocking can lead to engine
damage and should be corrected by refueling with higher octane unleaded
gasoline.
At minimum, the gasoline you use should meet the specifications of
ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.
