 Daytime running light system

The daytime running lights illuminate using the same lights as the parking

lights and illuminate brighter than the parking lights.

To make your vehicle more visible to other drivers during daytime driving,

the daytime running lights turn on automatically when all of the following

conditions are met. (The daytime running lights are not designed for use at

night.)

The engine is running

The parking brake is released

The headlight switch is in the

The daytime running lights remain on after they illuminate, even if the parking

brake is set again.

For the U.S.A.: Daytime running lights can be turned off by operating the

switch.

For the Canada: Daytime running lights are not designed for use at night.

Compared to turning on the headlights, the daytime running light system

offers greater durability and consumes less electricity, so it can help improve

fuel economy.

 Headlight control sensor (vehicles with automatic headlight system)

The sensor may not function properly if an

object is placed on the sensor, or anything

that blocks the sensor is affixed to the

windshield.

Doing so interferes with the sensor

detecting the level of ambient light and

may cause the automatic headlight sys-

tem to malfunction.

202

 Automatic light off system

onds after a door is opened and closed if the engine switch is turned to the

“ACC” or “LOCK” position. (The lights turn off immediately if the

on the key is pressed after all the doors are locked.)

button

When only the tail lights come on: The tail lights turn off automatically if the

engine switch is tuned to the “ACC” or “LOCK” position and the driver’s door

is opened.

Settings (automatic light off system) can be changed.

NOTICE

 To prevent battery discharge

Do not leave the lights on longer than necessary when the engine is not

running.

203

Automatic High Beam∗

The Automatic High Beam uses an in-vehicle camera sensor to

assess the brightness of streetlights, the lights of vehicles

ahead etc., and automatically turns the high beam on or off as

necessary.

WARNING

 Limitations of the Automatic High Beam

Do not rely on the Automatic High Beam. Always drive safely, taking care to

observe your surroundings and turning the high beam on or off manually if

necessary.

 To prevent incorrect operation of the Automatic High Beam system

Do not overload the vehicle.

 High beam automatic turning on or off conditions

When all of the following conditions are fulfilled, the high beam will be auto-

matically turned on (after approximately 1 second):

Vehicle speed is above approximately 21 mph (34 km/h).

The area ahead of the vehicle is dark.

There are no vehicles ahead with headlights or tail lights turned on.

There are few streetlights on the road ahead.

If any of the following conditions are fulfilled, the high beam will be automat-

ically turned off:

Vehicle speed drops below approximately 17 mph (27 km/h).

The area ahead of the vehicle is not dark.

Vehicles ahead have headlights or tail lights turned on.

There are many streetlights on the road ahead.

 Camera sensor detection information

The high beam may not be automatically turned off in the following situa-

tions:

When oncoming vehicles suddenly appear from a curve

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

When vehicles ahead are hidden from sight due to repeated curves, road

dividers or roadside trees

4

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 a vehicle ahead only has operational 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

206

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 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.

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 dis-

tress to other drivers or pedestrians nearby.

207

warm. The fluid may freeze on the windshield and cause low visibility. This

may lead to an accident, resulting in death or serious injury.

NOTICE

 When the windshield is dry
