The automatic light control sensor is on the top center of the
instrument panel.
Do not place anything on the instrument panel, and/or do not
affix anything on the windshield to block this sensor.
When you turn on the headlights, the lights automatically turn
off about 30 seconds after any of the doors is opened and
closed with the ignition switch turned to the “ACC” or “LOCK”\
position.* To turn them on again, turn the ignition switch to the
“ON” position, or turn the headlight switch off and then twist the
knob until the first or second clickstop. If you are going to park
for over one week, make sure the headlight switch is off.
When the headlight switch is on with all the doors locked and
the trunk closed, pushing the “LOCK” button on the wireless
remote control key turns off the headlights.
NOTE:
* The time before turning off the lights can be changed.
Ask your Lexus dealer for details. Daytime Running Light System
The headlights turn on at reduced intensity when the parking
brake is released with the engine started, even with the light
switch in the “OFF” position. They will not go off until the
ignition switch is turned off.
To turn on the other exterior lights and instrument panel lights,
twist the knob to the first clickstop.
Twist
the knob to the second clickstop to turn on the headlights
to full intensity for driving at night.
When setting the knob to the third clickstop (“AUTO”), the
headlights will automatic ally adjust to full intensity and/or turn
on the other lights depending on the darkness of the
surroundings. Likewise, as the surroundings become brighter,
the headlights will turn to reduced intensity, ultimately turning
off the other lights.
NOTICE

leave the lights on longer than necessary when the
engine is not running.

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 is on when the defogger is
operating.
The system will automatically shut off when the defogger has
operated about 15 minutes.

when the switch is on.
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 off. 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.
If the outside rear view mirrors are heavily coated with ice, use
a spray de −icer before operating the switch.
NOTICE
 When cleaning the inside of the rear window, be
careful not to scratch or damage the heater wires or
connectors.

FUEL GAUGE
13L062d
Low fuel level warning light
The gauge indicates the approximate quantity of fuel
remaining in the tank when the ignition switch is on.
It is a good idea to keep the tank over 1/4 full.
If the fuel level approaches “E” or the low fuel level warning light\
comes on, fill the fuel tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the fuel gauge needle may fluctuate or the low fuel level
warning light may come on earlier than usual.
If the fuel tank is completely empty, the malfunction indicator
lamp comes on. Fill the fuel tank immediately.
The indicator lamp goes off after driving several times. If the
indicator lamp does not go off, contact your Lexus dealer as
soon as possible. See the inner back cover for fuel capacity and recommended
fuel selection.
ENGINE COOLANT
TEMPERATURE GAUGE
13L151
 Normal range
The gauge indicates the engine coolant temperature when
the ignition switch is on. The engine operating
temperature will vary with changes in weather and engine
load.
If the needle points to the red zone or higher, stop your vehicle
and allow the engine to cool.
Your vehicle may overheat during severe operating conditions,
such as:
 Driving up a long hill on a hot day.
 Reducing speed or stopping after high speed driving.
