Before driving CAUTION■
Front passenger occupant classi fication system precautions●
Do not recline the front passenger seatback so far that it touches a rear seat. This
may cause the “AIR BAG OFF” indicator ligh t to be illuminate d, which indicates
that the passenger’s airbags will not deploy in the event of a severe accident. If the
seatback touches the rear se at, return the seatback to a position where it does
not touch the rear seat. Keep the front pa ssenger seatback as upright as possible
when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.●
If an adult sits in the front passenger se at, the “AIR BAG ON” indicator light is illu-
minated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the “AIR BAG OFF” indicator still rema ins illuminated, either ask the pas-
senger to move to the rear seat, or if th at is not possible, move the front passenger
seat fully rearward.●
When it is unavoidable to install the forw ard-facing child restraint system on the
front passenger seat, install the child rest raint system on the front passenger seat
in the proper order. (  P. 1 5 4 )●
Do not modify or remove the front seats.●
Do not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indicate a malfunction of the detection sys-
tem. In this case, contact your Lexus dealer immediately.●
Child restraint systems installed on the rear seat should not contact the front seat-
backs.●
Do not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.●
Do not modify or replace the upholstery of the front seat.

When driving
CAUTION■
If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on
when you start the hybrid system, this could mean that these systems are not avail-
able to help protect you in an accident, wh ich could result in death or serious injury.
Have the vehicle inspected by your Lexus dealer immediately if this occurs.■ Warning lights
Warning lights inform the driver of malfunctions in any of the vehi-
cle’s systems. (  P. 733)
* 1
: These lights turn on when the “POWER” switch is turned to ON mode
to indicate that a system check is being performed. They will turn off
after the hybrid system is on, or after a few seconds. There may be a
malfunction in a system if a light do es not come on, or if the lights do
not turn off. Have the vehicle inspected by your Lexus dealer.

■ Average vehicle speed
Displays the average vehicle speed since the function was reset The function can be reset by pushing the “ENTER” switch for longer than
one second when the average vehicle speed is displayed.
■ Cruising range
Displays the estimated maximum distan ce that can be driven with the
quantity of fuel remaining • This distance is computed based on your average fuel consumption. As
a result, the actual distance that can be driven may differ from that dis-
played.
• When only a small amount of fuel is added to the tank, the display may
not be updated.
When refueling, turn the “POWER” switch off. If the vehicle is refueled
without turning the “POWER” switch off, the display may not be
updated.
■ Tire inflation pressure
Displays inflation pressure of each tire. There is no correlation between
the order of the displayed values and the tire positions. If the inflation pressure of any tire drops a certain amount below the tire infla-
tion pressure value currently memorized in the system, the displayed values
will be highlighted.
It may take a few minutes to display the tire inflation pressure after the
“POWER” switch is turned to ON mode. It may also take a few minutes to
display the tire inflation pressure after inflation pressure has been adjusted.
If the tire pressure warning light is on or flashing, a message describing the
situation will be displayed.
