Driving
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to AUTO position while the “START STOP ENGINE”
<“POWER”> switch is in IGNITION ON mode, the wipers will operate once
to show that AUTO mode is activated.
●When the sensor sensitivity ring is turned toward high while in AUTO mode, the
wipers will operate once to indicate that the sensor sensitivity is enhanced.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F
(-30°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 wind-
shield 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 intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.
CAUTION
■Caution regarding the use of windshield wipers in AUTO mode (vehicles with
rain-sensing windshield wipers)
The windshield wipers may operate unexpect edly 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 ca ught 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.

Maintenance and care
◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Lexus dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits , cracks deep enough to expose the fabric,
and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consul t with your Lexus dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered, the
tire pressure warning system will not work properly. After driving for about 20 min-
utes, the tire pressure warning light blinks for 1 minute and stays on to indicate a sys-
tem malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has sel-
dom or never been used or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■When rotating the tires
Make sure that the “START STOP ENGINE” <“POWER”> switch is off. If the tires are
rotated while the “START STOP ENGINE” <“POWER”> switch is in IGNITION ON
mode, the tire position in formation will not be updated.
If this accidentally occurs, either turn the “START STOP ENGINE” <“POWER”>
switch to off and then to IGNITION ON mode, or initialize the system after
checking that the tire pressure is properly adjusted.

When trouble arises
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural
air leaks and tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with a tire
pressure warning valve and transmitter. If a tire goes flat, the tire pressure warning
light will not turn off even though the flat tire has been replaced with the spare tire.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure
warning valve and transmitter. The tire pressure warning light will turn on if the tire
inflation pressure of the spare tire is low. If a tire goes flat, the tire pressure warning
light will not turn off even though the flat tire has been replaced with the spare tire.
■Conditions that the tire pressure warning system may not function properly
P. 7 0 7
■If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1 minute when
the “START STOP ENGINE” <“POWER”> switch is turned to IGNITION ON
mode, have it checked by your Lexus dealer.
■Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and the warn-
ing buzzer may sound.
■Warning buzzer
In some cases, the buzzer may not be he ard because of noisy place or an audio
sound.
