NOTICE
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time. 
Doing so may damage the power steering pump.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.

following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of oil an d fluid used for the engine, transmission,

2-3. Operating the lights and windshield wipers
GX460_U.S.A. (OM60E69U)
●In the situations below, the system may not be able to correctly detect the sur-
rounding brightness levels, and may flash or expose nearby pedestrians to the
high beam. Therefore, you should consider turning the high beam on or off
manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The inside rear view mirror or camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights or
fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are chang-
ing color, or are not aimed properly.
• When driving through an area of intermittently changing brightness and darkness
• When frequently and repe atedly driving ascending/descending roads, or
roads with rough, bumpy or uneven surfaces (such as stone-paved roads,
gravel tracks etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• There is a highly reflective object ahead of the vehicle, such as a sign or a mir- ror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The Automatic High Beam indicator is flashing.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or distress to
other drivers or pedestrians nearby.

CAUTION
■Conditions which may affect the rear view monitor system
●If the back of the vehicle has been hit, the camera’s position and mounting angle
may have changed. Have the vehicle inspected by your Lexus dealer.
●As the camera has a water proof construction, do not detach, disassemble or
modify it. This may cause incorrect operation.
●Rapid temperature changes, such as when hot water is poured on the vehicle in
cold weather, may cause the system to function abnormally.
●If the camera lens is dirty, it cannot transmit a clear image. Rinse with water and
wipe with a soft cloth. If the camera lens is extremely dirty, wash with a mild
cleanser and rinse.
●Do not strongly rub the camera lens. If the camera lens is scratched, it cannot
transmit a clear image.
●Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to
the camera. If this happens, wipe it off as soon as possible.
●The displayed image may be darker and mo ving images may be slightly distorted
when the system is cold.
●Situations unsuitable for rear view monitor
• On icy or slick road surfaces, or in snow.
• When using tire chains or emergency tires.
• On roads that are not flat or straight, such as curves or slopes.
●When traveling on a sloping road, the ar ea displayed on the screen may change.
●If the tires are changed, the area displayed on the screen may change.
●When washing the vehicle, do not apply intensive bursts of water to the camera
or camera area. Doing so may result in the camera malfunctioning.

height control air suspension cannot be activated until the malfunction is cor-
rected. 

operating correctly. If the warning mess age continues to be displayed, have
your vehicle inspected by your Le xus dealer as soon as possible.

wires for transportation via flat bed truck (Turn off the rear height control air sus-
pension and stop the engine.)
●When the vehicle must be towed or disconnecting a trailer (Put the vehicle height
