TACHOMETER
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine overrevving.
Driving with the engine running too fast causes excessive
engine wear and poor fuel economy. Remember, in most
cases the slower the engine speed, the greater the fuel
economy.
It is not a malfunction even if the needle of the tachometer
returns to the bottom position when the ignition switch is turned
to the “START” position.
NOTICE
Do not let the indicator needle get into the red zone. This
may cause severe engine damage.
ODOMETER AND TRIP METER
 Trip meter reset knob
This meter displays the odometer and two trip meters. To
change the mode indication, push the trip meter reset
knob briefly. Each time you push the knob, the mode
changes in order from the odometer to trip meter A to trip
meter B, then back to the odometer, etc.
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 set the A trip meter to zero, display the A meter reading,
push the knob and hold it. The same applies for the B trip
meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.

(c) Front Passenger’s Seat Belt ReminderLight
This light reminds you to buckle up the front passenger’s seat
belt.
Once the ignition key is turned to “ON” or “START”, the
reminder light flashes if a passenger sits in the front passenger
seat and does not fasten the seat belt. Unless the front
passenger fastens the belt, the light stays flashing.
If luggage or other load is placed on the front passenger seat,
depending on its weight and how it is placed on the seat,
built−in sensors in the seat cushion may detect the pressure,
causing the reminder light to come on.
(d) SRS Warning Light
The indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the SRS airbags and front seat belt pretensioners
are operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources.
If either of the following conditions occurs, this indicates a
malfunction somewhere in the parts monitored by the warning
light system. Contact your Lexus dealer as soon as possible
to service the vehicle.
 When the ignition key is turned to the “ON” position, the light
does not come on, remains on or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front
passenger airbags have a problem. If the light flashes, the side
and curtain shield airbags and/or seat belt pretensioners have
a problem.

CAUTION
To avoid serious personal injury, you must do the
following.
 While the vehicle is moving, always keep the heads,
hands and other parts of the bodies of all occupants
away from the roof opening. Otherwise, they could
be seriously injured if the vehicle stops suddenly or
if the vehicle is involved in an accident.
 Before you close the moon roof, always make sure
there is nobody around the moon roof. You must also
make sure nobody places his or her head, hands and
other parts of the body in the roof opening. If
someone’s neck, head or hands get caught in the
closing roof, it could result in a serious injury. When
anyone closes the moon roof, first make sure it is safe
to do so.
 Never leave small children alone in the vehicle,
especially with the ignition key still inserted. They
could use the moon roof switches and get trapped in
the roof opening. Unattended children can be
involved in serious accidents.

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.)

COMFORT ADJUSTMENT

INSIDE REAR VIEW MIRROR
Adjust the mirror so that you can just see the rear of your
vehicle in the mirror.
Pushing the “MIRROR” switch changes the mode
between AUTO and DAY.
The indicator comes on when the AUTO mode is selected.
DAY mode: The mirror surface is normal.
AUTO mode: If the mirror detects light from the headlights
of the vehicle behind you, the mirror surface darkens
slightly to reduce the reflected light.
When the ignition key is inserted and turned on, the inside rear
view mirror always turns on in the AUTO mode. When the outside air temperature is low, it may take a little
longer for the mirror to darken in response to the detection of
headlights.
CAUTION
Do not adjust the mirror while the vehicle is moving.
Doing so may cause the
driver to mishandle the vehicle
and an accident may occur resulting in death or serious
injuries.
To ensure correct functioning of an antiglare mirror
sensor located on the back side of the mirror, do not touch
or cover the sensor with your finger or a piece of cloth, etc.
