2394-3. Operating the lights and wipers

Driving
IS300h_EE(OM53B95E)
The windshield wiper and washer can be operated when
The power switch is in ON mode.
Dripping prevention wiper sweep
After performing a washing and wiping operation several times, the wipers oper-
ate one more time after a short delay to prevent dripping.
However, the last sweep will not happen if the vehicle is traveling above 170 km/
h (106 mph).
Effects of vehicle speed on wiper operation (vehicles with rain-sensing wind-
shield wipers)
Vehicle speed affects the following even when the wipers are not in AUTO
mode.
Intermittent wiper interval
Wiper operation when the washer is being used (delay until drip prevention
wiper sweep occurs)
With low speed windshield wiper operation selected, wiper operation will be
switched from low speed to intermittent wiper operation only when the vehicle is
stationary.
Raindrop sensor (vehicles with rain-sensing windshield wipers)
If the wiper is turned to AUTO mode while the power switch is in ON mode,
the wipers 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 (vehicles with rain-sens-
ing windshield wipers)
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.
Operation guide display (vehicles with rain-sensing windshield wipers only)
When the windshield wiper switch is operated to activate AUTO mode or when
the rain-sensing level is adjusted, the current status is displayed on the meters for
a few seconds. (P. 1 1 9 )
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.

2404-3. Operating the lights and wipers
IS300h_EE(OM53B95E)
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 wipers.
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.
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.

Driving
IS300h_EE(OM53B95E)
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.
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 the 18-inch 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 freezing.
To ensure proper operation of the climate control system fan, remove
any snow that has accumulated on the air inlet vents in front of the
windshield.
Check for and remove any excess ice or snow that may have accumu-
lated on the exterior lights, vehicle’s roof, chassis, around the tires or
on the brakes.
Remove any snow or mud from the bottom of your shoes before get-
ting in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and the
vehicle ahead, and drive at a reduced speed suitable to road conditions.
Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
