SWITCHES
32To turn the electric rear window defogger on, push the
switch.
The ignition key must be in the “ON” position.
The thin heater wires on the inside of the rear window will
quickly clear the surface. An indicator light will illuminate to
indicate the defogger is operating.
The system will automatically shut off when the defogger has
operated about 15 minutes.
If further defrosting or defogging is desired, simply actuate the
switch again. When the
surface has cleared, push the switch
once again to turn the defogger of f. Continuous use may cause
the battery to discharge, especially during stop −and−go
driving. The defogger is not designed to dry rain water or to
melt snow.
NOTICE
 When cleaning the inside of the rear window, be
careful not to scratch or damage the heater wires or
connectors.
 To prevent the battery from being discharged, turn
the switch off when the engine is not running.
OUTSIDE REAR VIEW MIRROR
DEFOGGER SWITCH
To turn the electric outside rear view mirror defogger on,
push the switch.
The ignition key must be in the “ON” position.
The thin heater wires on the heater panels in the outside rear
view mirrors will quickly clear the surface. Keep your hands off
the mirror faces when the switch is on. An indicator light will
illuminate to indicate the defogger is operating.
The system will automatically shut off when the defogger has
operated about 5 minutes.

SWITCHES
37
SEAT HEATER SWITCHES
The seat heater has two dials; one marked “L” (for the
driver’s seat) and the other marked “R” (for the front
passenger’s seat). To turn the seat heaters on, turn the
dials forward. The indicator lights come on. To turn them
off, turn the dials backward until they stop. The indicator
lights go off.
You can adjust the heating temperature to 5 stages. To
increase the temperature, turn them forward. To decrease the
temperature, turn them backward.
The ignition key must be in the “ON” position.
CAUTION
Occupants must use caution when operating the seat
heater because they may experience minor burns even
at low temperatures. Use extra caution for;
 Babies, small children, elderly persons, sick persons
or handicapped persons
 Persons who have delicate skin
 Persons who are exhausted
 Persons who have taken alcohol or drugs which
induce sleep (sleeping drug, cold remedy, etc.).
To prevent the seat from overheating, do not use the
seat heater with a blanket, cushion, or other insulating
objects which cover the seat.
NOTICE
 Do not put unevenly weighted objects on the seat and
do not stick sharp objects (needles, nails, etc.) into
the seat.
 When cleaning the seats, do not use organic
substances (paint thinner, benzine, alcohol,
gasoline, etc.). They may damage the heater and seat
surface.
 To prevent the battery from being discharged, turn
the switches off when the engine is not running.

COMFORT ADJUSTMENT
11 5
Auto tilt away*
When the ignition key is removed, the steering column
moves forward away from the driver and also tilts up for
easy exit and entry.
When the key is inserted in the ignition switch, the steering
column returns to the previously set position.NOTE:
*This feature can be deactivated.
Ask your Lexus dealer for details.
OUTSIDE REAR VIEW MIRRORS
Adjust the mirror so that you can just see the side of your
vehicle in the mirror.
Be careful when judging the size or distance of any object seen
in the outside rear view mirror on the passenger’s side. It is a
convex mirror with a curved surface. Any object seen in a
convex mirror will look smaller and farther away than if seen in
a normal flat mirror.
When you push the outside rear view mirror defogger switch,
the heater panels in the outside rear view mirrors will quickly
clear the mirror surface. (See “Outside rear view mirror
defogger switch” on page 32.)
The rear view mirrors are rain clearing mirrors that clear the
driver’s rear view when it rains. (For details, see “Rain clearing
mirrors” on page 466.)
