■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexu s 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 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 refueling because sparks resulting fr om 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 fu el 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 pe rson or object that is statically charged.
This may cause static electricity to build up, resulting in a possible ignition hazard.

GX460_OM_OM60Q84U_(U)6-1. Maintenance and care
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to maintain
the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cl
eaners available. Use a sponge or brush to
apply the foam. Rub in overlapping circles. Do not use water. The excellent results are
obtained when keeping the ca rpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the belts
periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet. (P. 38)
An electrical malfunction ma y cause the airbags to deploy or not function properly,
resulting in death or serious injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. Th e instrument panel may reflect off the wind-
shield, obstructing the driver’s view and le ading to an accident, resulting in death or
serious injury.
NOTICE
■Cleaning detergents
●Do not use the following types of detergent, as they may discolor the vehicle interior
or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances su ch as benzene or gasoline, alkaline or
acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, su ch as thinner, benzene, and alcohol
●Do not use polish wax or polish cleaner. The instrument pane l’s or other interior part’s
painted surface may be damaged.

NOTICE
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used, the engine will be damaged.
●Do not use leaded gasoline.
Leaded gasoline can cause damage to your
vehicle’s three-way catalytic converters
causing the emission control system to malfunction.
●Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performance problems.
●Using unleaded gasoline with an octane numb er or rating lower than the level previ-
ously stated may cause pe rsistent heavy knocking.
At worst, this may lead to engine da mage and will void the vehicle warranty.
■Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is encoun-
tered after using a different type of fuel, discontinue the use of that type of fuel.
■When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.
