greater durability and consumes less

electricity, so it can help improve fuel

economy.

■

Headlight control sensor

The sensor may not function properly if an

object is placed on the sensor, or anything

that blocks the sensor is affixed to the wind-

shield.

Doing so interferes with the sensor detect-

AHB (Automatic High
Beam)

The Automatic High Beam uses a
camera sensor located behind the
upper portion of the windshield to
assess the brightness of the lights of
vehicles ahead, streetlights, etc.,
and automatically turns the high
beams on or off as necessary.

WARNING

■

Limitations of the Automatic High

Beam

Do not overly rely on the Automatic High

Beam. Always drive safely, taking care to

observe your surroundings and turning

the high beams on or off manually if nec-

LEXUS LS500h Owner's Manual

Driving

●

The high beams may be turned off if a

vehicle ahead that is using fog lights with-

out its headlights turned on is detected.

●

House lights, street lights, traffic signals,

and illuminated billboards or signs and

other reflective objects may cause the

high beams to change to the low beams,

or the low beams to remain on.

●

The following factors may affect the

amount of time taken for the high beams

to turn on or off:

• The brightness of the headlights, fog

lights, and tail lights of vehicles ahead

• The movement and direction of vehicles

ahead

• When a vehicle ahead only has opera-

tional lights on one side

• When a 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 in the vehicle

●

The high beams may turn on or off unex-

pectedly.

●

Bicycles or similar vehicles may not be

detected.

●

In the following situations the system may

not be able to correctly detect the sur-

rounding brightness level. This may cause

the low beams to remain on or the high

beams to flash or dazzle pedestrians or

vehicles ahead. In such a case, it is neces-

sary to manually switch between the high

and low beams.

• When driving in inclement weather

(heavy rain, snow, fog, sandstorms, etc.)

• When the windshield is obscured by fog,

mist, ice, dirt, etc.

• When the windshield is cracked or dam-

aged

• When the camera sensor is deformed or

dirty

• When the temperature of the camera

sensor is extremely high

• When the surrounding brightness level is

equal to that of headlights, tail lights or

fog lights

• When headlights or tail lights of vehicles

ahead are turned off, dirty, changing

color, or not aimed properly

• When the vehicle is hit by water, snow,

dust, etc. from a preceding vehicle

• When driving through an area of inter-

mittently changing brightness and dark-

ness

• When frequently and repeatedly driving

ascending/descending roads, or roads

with rough, bumpy or uneven surfaces

(such as stone-paved roads, gravel roads,

etc.)

• When frequently and repeatedly taking

curves or driving on a winding road

• When there is a highly reflective object

ahead of the vehicle, such as a sign or

mirror

• When the back of a preceding vehicle is

highly reflective, such as a container on a

truck

• When the vehicle’s headlights are dam-

aged or dirty, or are not aimed properly

• When the vehicle is listing or titling due to

a flat tire, a trailer being towed, etc.

• When the headlights are changed

between the high beams and low beams

repeatedly in an abnormal manner

• When the driver believes that the high

beams may be flashing or dazzling

Opening the fuel tank cap

The fuel tank of your vehicle has a
special structure, which requires a
reduction in fuel tank pressure
before refueling. After the opener
switch has been pressed, it will take
several seconds until the vehicle is
ready for refueling.

Before refueling the vehicle

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 refu-

eling 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 dis-

charged static electricity from their

body to come close to an open fuel

tank.
