■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If AUTO mode is selected while the engine switch is in IGNITION 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 wip-
ers 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 oper-
ate properly when sunlight from the rising or
setting of the sun intermittently strikes the
windshield, or if bugs etc. are present on the
windshield.
WARNING
■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield 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.

GS350_200t_GS F_OM_OM30F83E_(EE)
Perform the following according to the driving conditions: ●Do not try to forcibly open a window or move a wiper that is fr ozen. Pour
warm water over the frozen area to melt the ice. Wipe away the water imme-
diately 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 windsh ield.
● Check for and remove any excess ice or snow that may have accumulated 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 getting 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. ● Park the vehicle and move the shift lever to P without setting the parking
brake. The parking brake may freeze up, preventing it from being released. If
the vehicle is parked without setting the parking brake, make sure to block the
wheels.
Failure to do so may be dangerous because it may cause the vehicle to move
unexpectedly, possibly leading to an accident.
● If the vehicle is parked without setting the parking brake, confirm that the shift
lever cannot be moved out of P *.
* : The shift lever will be locked if it is attemp ted to be shifted from P to any other position
without depressing the brake pedal. If the shift lever can be shifted from P, there may
be a problem with the shift lock system. Have the vehicle inspected by any authorized
Lexus retailer or Lexus authorized repair er, or any reliable repairer immediately.

WARNING
■To prevent the windshield from fogging up
●Do not use during cool air operation in extremely humid weather. The d iffer-
ence between the temperature of the outside air and that of the windshield can cause
the outer surface of the windshield to fog up, blocking your vision.
■To prevent burns
●Do not touch the rear view mirror surfaces when the outside rear view mirror defog-
gers are on.
●Vehicles with windshield wiper de-icer: Do not touch the glass at lower part of the
windshield or to the side of the front pilla rs when the windshield wiper de-icer is on.
