GX460_OM_OM60M73U_(U)4-4. Refueling
Opening the fuel tank cap
●Turn the engine switch off and ensure that all the doors and windows are
closed.
●Confirm the type of fuel. (
P. 5 7 2 )
■Fuel types
 P. 5 7 2
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only accommo-
dates the special nozzle on unleaded fuel pumps.
Perform the following steps to open the fuel tank cap.
Before refueling the vehicle
CAUTION
■When refueling the vehicle
Observe the following precautions while refu eling the vehicle. Failure to do so may
result in death or serious injury.
●After exiting the vehicle and before openin g the fuel door, touch an unpainted metal
surface to discharge any static electricity. It is important to discharge static electricity
before refueling because sparks resulting fr om static electricity can cause fuel vapors
to ignite while refueling.
●Always hold the grips on th e fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened. Wait until the
sound cannot be heard before fully removing the cap. In hot weather, pressurized fuel
may spray out of the filler neck and cause injury.
●Do not allow anyone that has not discharged static electricity from their body to come
close to an open fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances th at are harmful if inhaled.
●Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch any person or object that is statically charged.
This may cause static electricity to build up, resulting in a possible ignition hazard.

When trouble arises
7-2. Steps to take in an emergency
Fuel pump shut off system
Follow the procedure below to restart the engine after the system is activated.Turn the engine switch to AC CESSORY mode or turn it off.
Restart the engine.
To minimize the risk of fuel leakage wh en 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 the ground, the fuel system has been damaged and
is in need of repair. Do not restart the engine.

Vehicle 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 Ti er Detergent Gasoline. For more informa-
tion on Top Tier Detergent Gasoline and a list of marketers, please go to the official
website www.toptiergas.com.
■Recommendation of the use of low emissions gasoline
Gasolines containing oxygenates such as et hers and ethanol, as well as reformulated
gasolines, are available in some cities. These fuels are typically acceptable for use, pro-
viding they meet other fuel requirements.
Lexus recommends these fuels, since the fo rmulations allow for reduced vehicle emis-
sions.
■Non-recommendation of the use of blended gasoline
●If you use gasohol in your Lexus, be sure that it has an octane rating no lower than 87.
●Lexus does not recommend the use of gasoline containing methanol.
■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcy clopenta-
dienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasolin e that contains MMT. If fuel containing
MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instru ment cluster may come on. If this happens,
contact your Lexus dealer for service.
●Use only gasoline containing up to 15% etha-
nol.
DO NOT use any flex-fuel or gasoline that
could contain more than 15% ethanol, includ-
ing from any pump labeled E30, E50, E85
(which are only some examples of fuel con-
taining more than 15% ethanol).DO NOT use gasoline
containing more than 15%
ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)
