■Effects of vehicle speed on wiper opera-
tion (vehicles with rain-sensing wind-
shield wipers)
Vehicle speed affects the Intermittent wiper
interval.
■Raindrop sensor (vehicles with rain-
sensing windshield wipers)
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs, etc. are
present on the windshield.
●If the wiper switch is turned to the AUTO
position while the power switch is in ON,
the wipers will operate once to show that
AUTO mode is activated.
●If the temperature of the raindrop sensor
is 194°F (90°C) or higher, or 5°F (-15°C)
or lower, automatic operation may not
occur. In this case, operate the wipers in
any mode other than AUTO mode.
■If no windshield washer fluid sprays
Check that the washer nozzles are not
blocked, if there is washer fluid in the
washer fluid tank.

etc. do not become caught in the wind-
shield wipers.
■Caution regarding the use of washer
fluid

the washer fluid pump may overheat.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer.

Driving
Use fluids that are appropriate to
the prevailing outside temperatures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
Have a service technician inspect
the condition of the 12-volt battery.
 It is recommended that the vehicle is
fitted with four snow run-flat tires or
purchase a set of tire chains for the
front tires.
Ensure that all tires are the same size and
brand, and that chains match the size of the
tires.
Perform the following according to the
driving conditions:
Do not try to forcibly open a window
or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water
immediately to prevent it from

WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehicle
being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower.
●Avoid driving on bumpy road surfaces
or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
●Slow down sufficiently before entering
a curve to ensure that vehicle control is
maintained.
●Do not use LTA (Lane Tracing Assist).
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.
