vated.

●

●

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.

221

■

Effects of vehicle speed on wiper operation (vehicles with rain-sensing windshield wip-

ers)
With the settings other than “AUTO” also, the time until drip prevention wiper sweep

occurs is changed depending on vehicle speed.

With the low speed wiper operation selected, wiper operation will be switched from low

speed to intermittent wiper operation only when the vehicle is stationary. (However,

when the sensor sensitivity is adjusted to the highest level, the mode cannot be switched.)

■

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.

CAUTION

■

Caution regarding the use of windshield wipers in “AUTO” mode (vehicles with rain-

sensing windshield wipers)
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 etc. anything

else does 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.

■

Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only accommo-

dates the special nozzle on unleaded fuel pumps.

Perform the following steps to open the fuel tank cap.

Before refueling the vehicle

CAUTION

■

When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so may

result in death or serious injury.

●

After exiting the vehicle and before opening the fuel door, touch an unpainted metal

surface to discharge any static electricity. It is important to discharge static electricity

before refueling because sparks resulting from static electricity can cause fuel vapors

to ignite while refueling.

●

Always hold the grips on the fuel tank cap and turn it slowly to remove it.

A whooshing sound may be heard when the fuel tank cap is loosened. Wait until the

sound cannot be heard before fully removing the cap. In hot weather, pressurized fuel

may spray out of the filler neck and cause injury.

●

Do not allow anyone that has not discharged static electricity from their body to come

close to an open fuel tank.

●

Do not inhale vaporized fuel.

Fuel contains substances that are harmful if inhaled.

●

Do not smoke while refueling the vehicle.

Doing so may cause the fuel to ignite and cause a fire.

●

Do not return to the vehicle or touch any person or object that is statically charged.

This may cause static electricity to build up, resulting in a possible ignition hazard.

226

CAUTION

■

When refueling
Observe the following precautions to prevent fuel overflowing from the fuel tank:

●

Securely insert the fuel nozzle into the fuel filler neck.

●

Stop filling the tank after the fuel nozzle automatically clicks off.

●

Do not top off the fuel tank.

NOTICE

■

Refueling
Do not spill fuel during refueling.

Doing so may damage the vehicle, such as causing the emission control systems to

operate abnormally or damaging fuel system components or the vehicle’s painted sur-

face.

227

Press the opener to open the fuel
filler door.

Turn the fuel tank cap slowly to open,
and hang the fuel tank cap on the
back of the fuel filler door.
