2-1. Driving procedures
GX460_U.S.A. (OM60J00U)
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.
Information on what to do in case of a flat tire ( →P. 7 2 1 )
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
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 and fluid used for the engine, transmission,
transfer, differentials, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

2-3. Operating the lights and windshield wipers
GX460_U.S.A. (OM60J00U)
●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 orfog 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 repeatedly 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.

NOTICE
■In the following situations, the LDA will not work, or will not perform reliably
●When the lane markers are interrupted or are not present, such as before a toll-
booth.
●When the lane markers are only on one side of the road.
●When driving on a sharp curve.
●When lanes are extremely narrow or extremely wide.
●When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure.
●When the following distance between your vehicle and the vehicle ahead is
extremely short.
●When the lane markers are broken or when “Botts’ dots” or “Raised pavement
markers” can be seen.
●When the lane markers are obscured or partially obscured by sand, dirt, etc.
●When driving on a particularly bright road surface, such as concrete.
●When driving on a road surface that is bright due to reflected light.
●When driving in a location where the light level changes rapidly, such as the
entrance to or exit from a tunnel.
●When sunlight or the headlights of oncoming vehicles are shining directly into the
camera lens.
●When pavement lane markers are difficult to see due to rain, snow, fog, etc.
●When driving on a road surface that is wet due to rain, standing water, etc.
●When the vehicle experiences strong up-and-down motion such as when driving
on an extremely rough road or on a seam in the pavement.
●When driving on roads that are branching or merging.
●When headlight brightness is reduced due to dirt on the lenses, or when the
headlights are misaligned.

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 moving 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 area 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.
