Raindrop sensor (vehicles with rain-sensing windshield wipers)
If AUTO mode is selected while the power switch is in ON mode, the wip-
ers will operate once to show that AUTO mode is activated.
If the temperature of the raindrop sensor is 85°C (185°F) or higher, or -
30°C (-22°F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than AUTO mode.
When the windshield wipers are in temporary operation
AUTO mode cannot be activated even if is pressed.
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
windshield washer fluid reservoir.
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 intermit-
tently strikes the windshield, or if bugs
etc. are present on the windshield.
CAUTION
Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched
or the windshield is subject to vibration in AUTO mode. Take care that
your fingers or anything else do not become caught in the windshield wip-
ers.
Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility.
This may lead to an accident, resulting in death or serious injury.

2924-3. Operating the lights and wipers
GS450h_300h_OM_OM30D53E_(EE)
NOTICE
When the windshield is dry
Do not use the wipers, as they may damage the windshield.
When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled
toward you and held continually.
When a nozzle becomes blocked
In this case, contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
When standing the windshield wipers up
Raise the wipers in line with the windshield. (P. 437)
Failure to do so may result in damage to the wipers and/or the hood.

and the headlights on, the headlight cleaners will operate once. (P. 285)
Washer fluid can be sprayed on the headlights.
NOTICE
When the washer fluid tank is empty
Do not press the switch continually as the washer fluid pump may overheat.

4344-6. Driving tips
GS450h_300h_OM_OM30D53E_(EE)
Winter driving tips
Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
Have a service technician inspect the condition of the 12-volt
battery.
Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the rear tires.
*
Ensure that all tires are the specified size and brand, and that chains
match the size of the tires.
*: Tire chains cannot be mounted on vehicles with front and rear tires of
differing sizes and vehicles with LDH and 19 inch tires
Carry out the necessary preparations and inspections before driv-
ing the vehicle in winter. Always drive the vehicle in a manner
appropriate to the prevailing weather conditions.

Wa s h e r f l u i d (P. 748)
• Water or washer fluid containing
antifreeze (for winter use)

CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
When working on the engine compartment
Make sure that the “POWER ON” on the multi-information display and
the “READY” indicator are both off.
Keep hands, clothing and tools away from the moving fan and engine
drive belt.
Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately. If you still experience dis-
comfort, consult a doctor.
