SWITCHES
23 Daytime Running Light System (Canada only)
The headlights turn on 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.
Under the daytime running light system, the headlights turn on at
reduced intensity. Twist the knob to the second clickstop to turn to
full intensity for driving at night.
When setting the knob to the third clickstop (”AUTO”), the
headlights will automatically 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
To prevent the battery from being discharged, do not leave the
lights on longer than necessary when the engine is not running.
Automatic headlight leveling system (Vehicles with
discharge headlight only)
As the headlight beam level is always maintained automatically at
the proper level in all loading conditions, your headlights do not
dazzle other road users.
If this system fails, the multi information display shows a message
”HEADLIGHT LEVELING”. If this occurs, have your vehicle
checked by Lexus dealer.

SWITCHES
26The time interval between sweeps is shortened when the vehicle
speed increases. When the vehicle speed reaches more than about
20 km/h (12 mph) with the interval adjuster in ”F” position, the time
interval becomes the shortest 1.5 seconds.
If you stop the vehicle with the wiper switch in the ”LO” position,
the wiper speed automatically changes from low speed to
intermittent operation speed.* This function does not work when the
interval adjuster is in the ”F” position.
NOTE: *This feature can be set inoperative. Ask your Lexus
dealer for details.
For mist wiper operation (a single wipe), pull the lever toward
you and release it.
To make the washer squirt, push the button on the end of the
lever.
If the wiper lever is in the ”OFF” position, the wipers will
automatically operate a couple of times and a few seconds later,
make a single wipe again to sweep the windshield completely.* The
last sweep does not happen if the vehicle speed exceeds about 170
km/h (106 mph).
NOTE: *The last single wipe can be set inoperative. Ask your
Lexus dealer for details.
The warning message ”LOW WASHER FLUID” is displayed in the
multi information display when the fluid level in the tank becomes
nearly empty. For information on adding washer fluid, see ”Adding
washer fluid” on page 261.
In cold weather, warm the windshield with the defroster before using
the washer. This will help prevent icing, which could block your
vision.
NOTICE
Do not operate the wipers if the windshield is dry. It may scratch
the glass.

SWITCHES
27
HEADLIGHT CLEANER SWITCH
(CANADA ONLY)
12L0072
To spray fluid on the headlights, push the switch with the
headlights on.
The ignition key must be in the ”ON” position.
The warning message ”LOW WASHER FLUID” is displayed in the
multi information display when the fluid level in the tank becomes
nearly empty. For information on adding washer fluid, see ”Adding
washer fluid” on page 261.
NOTICE
Do not turn the headlight cleaner on with the tank empty. It may
cause the cleaner motor to overheat.
REAR WINDOW AND OUTSIDE
REAR VIEW MIRROR DEFOGGER
SWITCH
12L008-4
To 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 and 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 is on when the defogger is operating.
The system will automatically shut off when the defogger has
operated about 15 minutes.

FUEL GAUGE
13L0011
Low fuel level warning light
The gauge is displayed when the ignition switch is on and
indicates the approximate quantity of fuel remaining in the tank.
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 fuelselection.
ENGINE COOLANT
TEMPERATURE GAUGE
13L0022
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.

ODOMETER AND TRIP METER
13L0041
This meter displays the odometer and two trip meters. To
change the mode indication, push the ”ODO/TRIP” button.
The odometer records the total distance the vehicle has been
driven. The twin trip meter records two different distances
independently.
For example, you can use one meter to calculate the fuel economy
and the other to measure the distance on each trip.
To change the trip meter indication from one trip to the other,
push the ”ODO/TRIP” button. To set the A trip meter to zero,
display the A meter reading, then push the ”RESET” button.
The same applies for the B trip meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.

occurs in your vehicle, a warning message appears in place of
cruise information. To change to the cruise information display,
push the ”FUNCTION” button.
