(6) Driving range(“Cruising Range miles” or “Cruising Range
km”)
The distance the vehicle can travel with the remaining fuel
is calculated and displayed based on the quantity of
remaining fuel and past fuel consumption.
The driving range display indicates the approximate distance
that you can drive until the fuel gauge reaches “E”. It is dif ferent
from the actual distance traveled.
The displayed value is updated every time the fuel equivalent
for 1 mile or 1 km is consumed.
The actual driving range varies with driving habits and road
conditions. If fuel consumption is good, the driving range will
be longer than indica ted. If fuel consumption is poor, the
driving range will be shorter than indicated.
If the low fuel level warning light comes on, refuel the vehicle
even if the display indicates that the vehicle can be driven
further.
INSTRUMENT PANEL LIGHT CONTROL
To adjust the brightness of the instrument panel lights,
turn the knob.
With the knob turned fully clockwise, the intensity of the

NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the front seat belt

This indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the 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 passenger occupant classification system, “AIRBAG ON”
indicator light, “AIRBAG OFF” indicator light, front passenger’s
seat belt buckle switch, front seat belt pretensioner
assemblies, inflators, warning light, interconnecting wiring and

The SRS front airbag system consists mainly of the above
components, and their locations are shown in the illustration.
The airbag sensor assembly consists of a safing sensor and
airbag sensor. The airbag sensors constantly monitor the forward
deceleration of the vehicle. If an impact results in a forward
deceleration beyond the designed threshold level, the system
triggers
the airbag inflators. At this time a chemical reaction in
the inflators very quickly fills the airbags with non− toxic gas to
help restrain the forward motion of the occupants. The front
airbags then quickly deflate, so that there is no obstruction of
the driver’s vision should it be necessary to continue driving.
When the airbags inflate, they produce a loud noise and
release some smoke and residue along with non −toxic gas.
This does not indicate a fire. This smoke may remain inside the
vehicle for some time, and may cause some minor irritation to
the eyes, skin or breathing. Be sure to wash off any residue as
soon as possible to prevent any potential skin irritation with
soap and water. If you can safety exit from the vehicle, you
should do so immediately.

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 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 passenger occupant classification system, “AIRBAG ON”

and warning buzzers” on page 74.)
If any of the following conditions occurs, this indicates a
malfunction of the airbags or seat belt pretensioners. Contact
your Lexus dealer as soon as possible. 
The light does not come on when the ignition key is turned
to the “ON” position or remains on for more than 6 seconds
or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the SRS driver and front
passenger airbags and/or front passenger occupant
classification system, “AIRBAG ON” indicator light and
“AIRBAG OFF” indicator light fail. If the light flashes, the SRS
side and curtain shield airbags have a problem.
The SRS warning light and “AIRBAG OFF” indicator light will
be illuminated if there is a malfunction in the front passenger
occupant classification system.
