Yep.
From the manual:XENON HEADLIGHTS (if so equipped)WARNINGHIGH VOLTAGE. When xenon headlights are on, theyproduce a high voltage. To preventan electric shock, never attempt tomodify or disassemble. Always haveyour xenon headlights replaced at aNISSAN dealer.. Xenon headlights provide considerablymore light than conventionalheadlights. If they are not correctlyaimed, they might temporarily blindan oncoming driver or the driverahead of you and cause a seriousaccident. If headlights are not aimedcorrectly, immediately take your vehicleto a NISSAN dealer and havethe headlights adjusted correctly.When the xenon headlight is initially turned on,its brightness or color varies slightly. However,the color and brightness will soon stabilize.. The life of xenon headlights will beshortened by frequent on-off operation.It is generally desirable not to turnoff the headlights for short intervals(for example, when the vehicle stops ata traffic signal).. If the xenon headlight bulb is close toburning out, the brightness will drasticallydecrease, the light will startblinking, or the color of the light willbecome reddish. If one or more of theabove signs appear, contact a NISSANdealer.SIC2745Type ASIC3019Type BHEADLIGHT AND TURN SIGNALSWITCHInstruments and controls 2-25
