CAUTION
■Road accident cautions
Observe the following precautions to reduce the risk of injury.
●Pull your vehicle off the road, put the shift lever in “P”, apply the parking brake,
turn the hybrid system off.
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside your vehicle, an electric shock may
occur. Never touch exposed electric wires.
●If a fluid leak occurs, do not touch it as it may be strong alkaline electrolyte from
the hybrid battery (traction battery). If it comes into contact with your skin or
eyes, wash it off immediately with a large amount of water or if possible, boric
acid solution. Seek immediate medical attention.
●If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never
use a fire extinguisher that is not meant for electric fires. Using even a small
amount of water may be dangerous.
●If your vehicle needs to be towed, do so with the rear wheels raised. If the wheels
with the electric motor (t raction motor) are on the ground when towing, the
motor may continue to generate electricit y. This may cause an electricity leakage
leading to a fire.(
P. 4 2 0 )
■Nickel-metal hydride battery
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of improp-
erly, it is hazardous to the environment and there is a risk of severe burns and elec-
trical shock that may result in death or serious injury.
■Emergency shut off system
●Carefully check to see if there are exposed high voltage parts or cables. Never
touch the parts or cables. (
P. 5 )
●Carefully inspect the ground under the vehicle. If you find that liquid has leaked
onto the ground, the fuel system may have been damaged. Leave the vehicle as
soon as possible.

Driving position memory system (if equipped)
Your preferred driving position (the position of the driver's seat, steering
wheel and outside rear view mirrors) can be entered into the computer's
memory and recalled with the touch of a button. It is also possible to set this
function to activate automatically when the doors are unlocked.

Three different driving positions can be entered into memory.
The same buttons are found on the front passenger's side, allowing the
position of the fr

ont passenger's seat to be memorized.
■Entering a position to memory
Check that the shift lever is set in “P”.
Switch to “IG-ON” mode.
Adjust the driver’s seat, steering wheel, and outside r
ear view
mirrors to the desired positions.
While pushing the “SET” button,
push button
“1”, “2” or “3” until
the signal beeps.
If the selected button has
already been preset, the previ -
ously recorded position will be
o
verwritten.

be act
ivated within 30 seconds after the co rresponding side door is opened, even if
the power switch is in the “OFF” mode.
■If any position memory button is push ed while the adjustments are being made
The operation will stop. To reactivate the sy st
em, push the desired button (“1” or “2”)
again.

1-8. Safety information

Before driving
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemica l reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu -
pants.
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the front seats, and parts of the front pillar and roof side rail, may be hot
for several minutes. The airbag itself may also be hot.
●The windshield may crack.
■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col -
lision in the U.S.A. and 18 mph (30 km/h) collision in Canada when the vehicle
impact
s straight into a fixed barrier that does not move or deform.
However, this threshold velocity will be considerably higher if the vehicle strikes
a
n object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi -
cle is very close to the designed thresh ol
d level, the SRS front airbags and the
seat belt pretensioners ma y not activate together.
●The SRS front passenger airbag will not activate, if there is not passenger sitting
in the front passenger seat. However, th e front passenger airbag may deploy, if
luggage is put in the seat or the seat belt is buckled up, regardless of the pres -
ence of an occupant in the seat.

1-8. Safety information
■When to contact your Lexus dealer
In the following cases, contact your Lexus dealer as soon as possible. Do not dis-
connect the 12 volt battery cables before contacting your Lexus dealer.
●Any of the SRS airbags have been inflated.
●The front of the vehicle is damaged or
deformed, or was involved in an accident
that was not severe enough to cause the
SRS airbags to inflate.
●A portion of the doors is damaged or
deformed, or the vehicle was involved in an
accident that was not severe enough to
cause the SRS side airbags and curtain
shield airbags to inflate.
●The pad section of the steering wheel, front
passenger airbag cover or lower portion of
the instrument panel is scratched, cracked,
or otherwise damaged.
●The surface of the seats with the side air-
bag is scratched, cracked, or otherwise
damaged.
●The portion of the front pillars, rear pillars
or roof side rail garnishes (padding) con-
taining the curtain shield airbags is
scratched, cracked, or otherwise dam-
aged.
