1-7. Safety information
1
Before driving
GX460_U.S.A. (OM60J00U)Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment power for the driver and front passen-
ger. The driver airbag system consists of the driver’s seat belt buckle
switch etc. The front passenger’s airbag system consists of the front pas-
senger occupant classification sensor etc.
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and a main sensor.
In certain types of severe frontal or side impacts or a vehicle rollover, the
SRS airbag system triggers the airbag inflators. A chemical reaction in
the inflators quickly fills the airbags with non-toxic gas to help restrain the
motion of the occupants.

CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (→P. 257) will not be activated, and a fatal or serious accident
may result.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane
■Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the following conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a fatal or serious accident may
result:
●When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable
●When the vehicle ahead of you decelerates suddenly
●Excessive exhaust gas (black smoke) is coming from the vehicle ahead or other
vehicles around you, obscuring your front view
●The rear section of the vehicle ahead is extremely dirty
●The vehicle ahead has higher ground clearance

NOTICE
■Cleaning detergents
●Do not use the following types of detergent, as they may discolor the vehicle inte-
rior or cause streaks or damage to painted surfaces.
• Non-seat portions: Organic substances such as benzene or gasoline, alkalineor acidic solutions, dye, or bleach.
• Seats: Acidic solutions, such as thinner, benzene, or alcohol.
●Do not use polish wax or polish cleaner. The instrument panel’s or other interior
part’s painted surface may be damaged.
■Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of leather
surfaces:
●Remove any dust or dirt from leather surfaces immediately.
●Do not expose the vehicle to direct sunlight for extended periods of time. Park
the vehicle in the shade, especially during summer.
●Do not place items made of vinyl, plastic, or containing wax on the upholstery, as
they may stick to the leather surface if the vehicle interior heats up significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes into
contact with electrical components such as the audio system above or under the
floor of the vehicle. Water may also cause the body to rust.
■Cleaning the inside of the rear window
●Do not use glass cleaner to clean the rear window, as this may cause damage to
the rear window defogger heater wires or antenna. Use a cloth dampened with
lukewarm water to gently wipe the window clean. Wipe the window in strokes
running parallel to the heater wires or antenna.
●Be careful not to scratch or damage the heater wires or antenna.

■Gasoline quality standards
●Automotive manufacturers in the U.S.A., Europe and Japan have developed a
specification for fuel quality called the World-Wide Fuel Charter (WWFC),
which is expected to be applied worldwide.
●The WWFC consists of four categories that are based on required emission
levels. In the U.S., category 4 has been adopted.
●The WWFC improves air quality by lowering emissions in vehicle fleets, and
improves customer satisfaction through better performance.
■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 detergent additives to clean and/or keep
clean intake systems.
■Recommendation of the use of cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxygen-
ates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many
areas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended
reformulated gasoline. These types of gasoline provide excellent vehicle perfor-
mance, reduce vehicle emissions and improve air quality.

NOTICE
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used, the engine will be dam-
aged.
●Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic convert-
ers 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 number or rating lower than the level
previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■Fuel-related poor driveability
If poor driveability is encountered after using a different type of fuel (poor hot start-
ing, vaporization, engine knocking, etc.), discontinue the use of that type of fuel.
■When refueling with gasohole
Take care not to spill gasohol. It can damage your vehicle’s paint.
