When driving
Turning on the high beam headlights
With the headlights on, push the
lever forward to turn on the high
beams.
Pull the lever back to the center
position to turn the high beams off.

on the high beams.

■Daytime running light system
●Vehicles with halogen headlights: to make your vehicle more visible to other
drivers, the headlights turn on automatically (at a reduced intensity) whenever
the engine is started and the parking brake is released. Daytime running lights
are not designed for use at night.
Vehicles with discharge headlights: to make your vehicle more visible to other
drivers, the parking lights turn on auto matically (at a increased intensity) when-
ever the engine is started and the parking brake is released. Daytime running
lights are not designed for use at night.
●Compared to turning on th e headlights, the daytime running light system offers
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 detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

immediately if on the key is pressed after both side doors are locked.)
●When only the tail lights come on: The tail lights turn off automatically if the
“ENGINE START STOP” switch is switched to ACCESSORY mode or turned
OFF and driver’s door is opened.
To turn the lights on again, switch to IGNITION ON mode, or turn the light switch
off once and then back to or
.
■Automatic headlight leveling system (vehicles with discharge headlights)
The level of the headlights is automatica lly adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights do
not interfere with other road users.
