Camera sensor detection information

●

The high beam may not be automatically turned off in the following situations:

●

• When oncoming vehicles suddenly appear from a curve

• When the vehicle is cut in front of by another vehicle

• When vehicles ahead are hidden from sight due to repeated curves, road dividers or roadside trees

• When vehicles ahead appear from the faraway lane on wide road

• When vehicles ahead have no lights

The high beam may be turned off if a vehicle ahead that is using fog lights without using the headlights is detected.

●

●

House lights, street lights, traffic signals, and illuminated billboards or signs may cause the high beam to switch to the low beams, or the low beams to remain on.

The following factors may affect the amount of time taken to turn the high beam on or off:

●

●

●

• The brightness of headlights, fog lights, and tail lights of vehicles ahead

• The movement and direction of vehicles ahead

• When vehicle ahead only has operational lights on one side

• When vehicle ahead is a two-wheeled vehicle

• The condition of the road (gradient, curve, condition of the road surface etc.)

• The number of passengers and amount of luggage

The high beam may be turned on or off when the driver does not expect it.

Bicycles or similar objects may not be detected.

In the situations shown below, the system may not be able to accurately detect surrounding brightness levels. This may cause the low beams to remain on or the high beams to cause problems for pedestrians, vehicles ahead or other parties. In these cases, manually switch between the high and low beams.

• In bad weather (rain, snow, fog, sandstorms etc.)

• The windshield is obscured by fog, mist, ice, dirt etc.

• The windshield is cracked or damaged.

• The camera sensor is deformed or dirty.

• The camera sensor temperature is extremely high.

• Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.

• Vehicles ahead have headlights that are either switched off, dirty, are changing color, or have are not aimed properly.

• When driving through an area of intermittently changing brightness and darkness.

• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved roads, gravel tracks etc.).

• When frequently and repeatedly taking curves or driving on a winding road.

• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.

• The back of a vehicle ahead is highly reflective, such as a container on a truck.

• The vehicle’s headlights are damaged or dirty, or are not aimed properly.

• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.

• The high beam and low beam are repeatedly being switched between in an abnormal manner.

• The driver believes that the high beam may be causing problems or distress to other drivers or pedestrians nearby.

4-3. Operating the lights and wipers

Switching between the intermittent windshield wipers and rain-sensing windshield wipers (vehicles with rain-sensing windshield wipers)

The wipers can be used as intermittent windshield wipers, which operate regardless of vehicle speed or amount of raindrops. The intermittent windshield wiper operation can be switched when the vehicle is stopped and the wiper is off. The wiper operation cannot be switched during AUTO mode or while the intermittent windshield wipers are operating.

Press and hold until the AUTO mode indicator stops flashing.

If is pressed and held until the

AUTO mode indicator stops flashing again, it will return to its previous state.

■

The windshield wiper and washer can be operated when

The engine switch is in IGNITION ON mode.

■

Dripping prevention wiper sweep

After washing and wiping operation several times, the wipers operate one more time after a short delay to prevent dripping.

■

However, the last sweep will not happen while the vehicle is moving.

Effects of vehicle speed on wiper operation

●

●

Intermittent windshield wipers interval changes when the vehicle is stopped.

With low speed operation selected, wiper operation will be switched from low speed to intermittent operation only when the vehicle is stationary.

■

Raindrop sensor

●

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.

●

●

If AUTO mode is selected while the engine switch is in IGNITION ON mode, the wipers will operate once to show that AUTO mode is activated.

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.

■

When the windshield wipers are in temporary operation

227

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.

WARNING

■

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.

4

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 your Lexus dealer.

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. 320)

Failure to do so may result in damage to the wipers and/or the hood.

4-4. Refueling

Opening the fuel tank cap

Perform the following steps to open the fuel tank cap:

Before refueling the vehicle

●

●

Turn the engine switch off and ensure that all the doors and windows are closed.

Confirm the type of fuel.

■

■

Fuel types

→P. 556

Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your vehicle has a fuel tank opening that only accommodates the special nozzle on unleaded fuel pumps.

WARNING

■

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 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.

■

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.
