4-4.Refueling
Turn the engine switch off.
 When closing the soft top roof,
ensure that both side doors, side
windows and rear quarter windows
are closed.
 Confirm the type of fuel.
■Fuel types
 P.357
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehi-
cle has a fuel tank opening that only accom-
modates the special nozzle on unleaded
fuel pumps.
■If the malfunction indicator lamp illumi-
nates
The malfunction indicator lamp may illumi-
nate erroneously if refueling is performed
repeatedly when the fuel tank is nearly full.
Opening the fuel tank cap
Before refueling the vehicle
WARNING
■When refueling the vehicle
Observe the following precautions while
refueling the vehicle. Failure to do so
may result in death or serious injury.
●After exiting the vehicle and before
opening the fuel door, touch an
unpainted metal surface to discharge
any static electricity. It is important to
discharge static electricity before refu-
eling because sparks resulting from
static electricity can cause fuel vapors
to ignite while refueling.
●Always hold the grips on the 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 the filler neck and cause injury.
●Do not allow anyone that has not dis-
charged static electricity from their
body to come close to an open fuel
tank.
●Do not inhale vaporized fuel.
Fuel contains substances that are
harmful if inhaled.
●Do not smoke while refueling the vehi-
cle.
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 refueling
Observe the following precautions to
prevent fuel overflowing from the fuel
tank:
●Securely insert the fuel nozzle into the
fuel filler neck.
●Stop filling the tank after the fuel noz-
zle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such
as causing the emission control system to
operate abnormally or damaging fuel
system components or the vehicle’s
painted surface.

7
When trouble arises
Vehicle pulls heavily to one side
when driving on a level road
 Loss of brake effectiveness, spongy
feeling, pedal almost touches the
floor
Follow the procedure below to restart
the engine after the system is activated.
1
Turn the engine switch to ACC or
turn it off.
2
Restart the engine.
Fuel pump shut off system
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.
Restarting 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 dam-
aged and is in need of repair. Do not
restart the engine.

Vehicle specifications
■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.
■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 Tier Detergent Gasoline. For more
information on Top Tier Detergent Gas-
oline and a list of marketers, please go to
the official websit e www.toptiergas.com.
■Recommendation of the use of low
emissions gasoline
Gasolines containing oxygenates such as
ethers and ethanol, as well as reformulated gasolines, are available in some cities.
These fuels are typically acceptable for use,
providing they meet other fuel require-
ments.
Lexus recommends these fuels, since the
formulations allow for reduced vehicle
emissions.
■Non-recommendation of the use of
blended gasoline
●Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from
any pump labeled
E30 (30% ethanol [ ]), E50 (50%
ethanol [ ]), E85 (85% ethanol [ ])
(which are only some examples of fuel
containing more than 15% ethanol).
●If you use gasohol in your vehicle, be sure
that it has an octane rating no lower than
91.
●Lexus does not recommend the use of
gasoline containing methanol.
■Non-recommendation of the use of gas-
oline containing MMT
Some gasoline contains an octane enhanc-
ing additive called MMT (Methylcyclopen-
tadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gas-
oline that contains MMT. If fuel containing
MMT is used, your emission control system
may be adversely affected.
The malfunction indicator lamp on the
instrument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
■If your engine knocks
●Consult your Lexus dealer.
●You may occasionally notice light knock-
Fuel information
You must only use unleaded gaso-
line.
Select premium unleaded gasoline
with an octane rating of 91
(Research Octane Number 96) or
higher required for optimum
engine performance and fuel econ-
omy. If the octane ra ting is less than
91, damage to the engine may
occur and may void the vehicle
warranty.
At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A..
