Driving
■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving, the day-
time running lights turn on automatically whenever the engine is started and the
parking brake is released with the headlight switch in the or “AUTO” position.
(Illuminate brighter than the parking lights.)
Daytime running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel econ-
omy.
■Headlight control sensor
■Automatic light off system
When the light switch is in or : The headlights and tail lights turn off 30 sec-
onds after the engine switch is turned to ACCESSORY mode or turned off and a
door is opened and all of the doors and trunk are closed. (The lights turn off immedi-
ately if on the key is pressed twice after all the doors are closed.)
To turn the lights on again, turn the engine switch to IGNITION ON mode, or turn
the light switch off once and then back to or .
If any of the doors or trunk lid is kept open, the lights automatically turn off after 20
minutes.
■Light reminder buzzer
A buzzer sounds when the engine switch is turned off or turned to ACCESSORY
mode and the driver’s door is opened while the lights are turned on.
■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of pas-
sengers and the loading condition of the vehi cle to ensure that the headlights do not
interfere with other road users. 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 detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

4-3. Operating the lights and 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

Driving
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●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
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 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
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.
