5-1. Essential information
Fuel pump shut off system
Follow the procedure below to restart the engine after the system is acti-
vated.
Turn the “ENGINE START STOP” switch to ACCESSORY mode
or turn it off.
Restart the engine.
NOTICE
nBefore starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto 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 when an air-
bag inflates upon collision, the fuel pump shut off system stops the supply of
fuel to the engine.

6-1. Specifications
Fuel information
nFuel 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.
nIf your engine knocks
lConsult your Lexus dealer.
lYou may occasionally notice light knocking for a short time while accelerating
or driving uphill. This is normal and there is no need for concern.
nGasoline 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. Per-
sistent 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.
