SWITCHES
26
For signaling turns, move the lever up or down in the
conventional manner.
The ignition key must be in the “ON” position.
The turn signal is self−cancelling after a turn, but after a lane
change, you may have to cancel it by hand. You can also signal
a lane change by moving the turn signal lever partway and
holding it there.
If the green light in the instrument cluster flashes faster than
normal, it indicates that the front or rear turn signal bulb has
burned out. If this indicator light does not come on, the fuse
or the indicator light itself has probably failed.
FOG LIGHT SWITCH
To turn on the fog lights, turn the switch to the “ON”
position. The fog lights come on only when the headlights
are on low beam.

AUDIO
201
Turn this knob to the right to step up the frequency or to
the left to step down.
Your radio automatically changes to stereo reception when a
stereo broadcast is received. “ST” appears on the display. If
the signal becomes weak, the radio reduces the amount of
channel separation to prevent the weak signal from creating
noise. If the signal becomes extremely weak, the radio
switches from stereo to mono reception. In this case, “ST”
disappears from the display.(b) Presetting a station

2. Push
one of the station selector buttons ( 16 ) and hold
it until a beep is heard. This sets the station to the button
and the button number ( 16 ) appears on the display.
Each button can store one AM station and two FM stations. To
change the preset station to a different one, follow the same
procedure.
The preset station memory is cancelled when the power
source is interrupted by battery disconnection or a blown fuse.

Link System, you will hear “A Lexus Link System error has
been detected. Please contact your Lexus dealer.” If you hear
this message, take your vehicle to your Lexus dealer.
