Instantaneous fuel consumption mode
Instantaneous fuel consumption is calculated and
displayed based on distance and fuel consumption for 2
seconds with the engine running.
The displayed value is updated every 2 seconds.
Note that an accurate figure may not be shown in the following
cases.
 When the vehicle is stopped with the engine running, the
display will indicate extremely high fuel consumption.
 When the vehicle is driving down a long slope, with the
engine brake applied, the display will indicate extremely low
fuel consumption.
To reset the calculations, push and hold the “RESET” button for
more than 1 second. 
Driving range modeThe 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 required to
travel 0.6 miles (1 km) is consumed.
Every time you refuel the vehicle, the calculation is reset.
The actual driving range varies with driving habits and road
conditions. If fuel consumption is good, the driving range will
be longer. If fuel consumption is poor, the driving range will be
shorter.
If the low fuel level warning light comes on, refuel even if the
display indicates that the vehicle can be driven further.

(c) Erasing the entire HomeLink memory (all
three programs)
To erase all previously programmed codes at one time, press
and hold down the 2 outside buttons for 20 seconds until the
indicator light flashes.
If you sell your vehicle, be sure to erase the programs stored
in the HomeLink
 memory.
CAUTION
 When programming the HomeLink Universal
Transceiver, you may be operating a garage door or
other device. Make sure people and objects are out
of the way of the garage door or other device to
prevent potential harm or damage.
 Do not use this HomeLink
 Universal Transceiver
with any garage door opener that lacks the safety
stop and reverse feature as required by federal safety
standards. (This includes any garage door opener
model manufactured before April 1, 1982.) A garage
door opener which cannot detect an object (signaling
the door to stop and reverse), does not meet current
federal safety standards. Using a garage door opener
without these features increases risk of serious
injury or death.
CUP HOLDERS

 In front of the rear console box
To use the cup holder, push the cup holder lid.
The cup holder is designed for holding cups or drink −cans
securely.
The cup holder can be adjusted to the size of the cups by
changing the separator position or moving the separator arms.
You can use it as an accessory box by removing the separator
inside.

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 seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. (For details, see
“Service remi nder indicators and warning buzzers” on page 43
for instructions.) 1 Front airbag sensors

2 Seat belt pretensioner assemblies

3 SRS warning light

4 Airbag sensor assembly
The front seat belt pretensioner system consists mainly of the
above components, and their locations are shown in the
illustration.
The front seat belt pretensioners are controlled by the airbag
sensor assembly. The airbag sensor assembly consists of a
safing sensor and airbag sensor.
When the front seat belt pretensioners are activated, an
operating noise may be heard and a small amount of
smoke−like gas may be released. This gas is harmless and
does not indicate that a fire is occurring.
Once the front seat belt pretensioners have been activated, the
seat belt retractors remain locked.

CAUTION
The SRS curtain shield airbags inflate with considerable
force. To avoid potential death or serious injury when
they inflate, the driver, front passenger and second
outside passengers must:
Wear their seat belts properly.
 Remain properly seated with their back upright and
against the seat at all times.
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 seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. (For details, see
“Service reminder indicators and warning buzzers” on page 43
for instructions.)
The SRS front airbags are designed to deploy in severe
(usually frontal) collisions where the magnitude and
duration of the forward deceleration of the vehicle
exceeds the designed threshold level.

11 Airbag sensor assembly
The SRS 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. In an impact results in a forward
deceleration beyond the designed threshold level, the system
triggers the airbag inflators. In a severe side impact, the side
and curtain shield airbag sensor and/or the curtain shield
airbag sensor trigger(s) the si
de and curtain shield airbag
inflators and/or the curtain shield airbag inflator. At this time a
chemical reaction in the inflators very quickly fills the airbags
with non −toxic gas to help restrain the forward or lateral 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 physically and safely exit the vehicle
after a collision, you should do so at the first opportunity.

STARTING AND DRIVING
314
4Resetting to a slower speed
Press the control lever downward in the “ − SET” direction and
hold it. Release the lever when the desired speed is attained.
While the lever is held downward, the vehicle speed will
gradually decrease.
When the difference between the actual vehicle speed and the
set speed is less than 5 km/h (3 mph), the set speed can be
lowered 1.6 km/h (1 mph) each time by pressing the control
lever downward in the “ − SET” direction quickly within 0.6
seconds.
However, a quicker way to reset is to depress the brake pedal
and then press the control lever downward in the “ − SET”
direction.
Even if you downshift the transmission from the “D” position to
“4” position with the cruise control on, engine braking will not
be applied because the cruise control is not cancelled. To
decrease the vehicle speed, reset to a slower speed with the
cruise control lever or depress the brake pedal. If you use the
brake pedal, cruise control is cancelled.
5Resuming the preset speed
If the preset speed is cancelled by pulling the control lever or
by depressing the brake pedal, pushing the lever up in the “+
RES” direction will restore the speed set prior to cancellation.
However, once the vehicle speed falls below about 40 km/h (25
mph), the preset speed will not be resumed.
Cruise control failure warning
If the “CRUISE” indicator light in the instrument cluster flashes
when using the cruise control, push the main switch to turn the
system off and then push it again to turn it on.
If any of the following conditions then occurs, there is some
trouble in the cruise control system.
 The indicator light does not come on.
 The indicator light flashes again.
 The indicator light goes out after it comes on.
If this is the case, contact your Lexus dealer and have your
Lexus inspected.
