The daytime running lights illuminate using th e same lights as the parking lights and illu-
minate 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 a ll 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 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.●
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.●

ning light, on the same side, is turned off. For emergency flashers, both are turned off. ■

ing brightness level. This may cause the lo w beams to remain on or the high beams to
flash or dazzle pedestrians or vehicles ahead. In such a case, it is necessary to manually
switch between the high and low beams.
• When driving in inclement weather (heavy ra in, snow, fog, sandstorms, etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.

• When the surrounding brightness level is equal to that of he adlights, 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 intermittently changi ng brightness and darkness
• When frequently and repeated ly driving ascendin g/descending roads, or roads with

• When frequently and repeatedly taking curves or driving on a winding road
• When there is a highly reflective object ahea d 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
