■Hybrid battery air vent
Hybrid battery air vent
There is an air intake vent on the
package tray for the purpose of
cooling the hybrid battery (trac-
tion battery). If the vent becomes
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
Emergency shut off system
The emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel leakage
when a certain level of impact is detected by the impact sensor. If the
emergency shut off system activates, your vehicle will not restart. To
restart the hybrid system, contact your Lexus dealer.
Energy monitor/consumption screen
You can view the status of your hybrid system on the multi-information
display (P. 168) and the touch screen (P. 242). The following images
are examples only, and may vary slightly from actual conditions.
■Energy monitor
●How to display on the touch screen:
Press .
Touch “Fuel Consumption” on the “Information” screen.
If the “Energy Monitor” screen does not appear, touch “Energy”.
●How to display on the multi-information display:
Push the “DISP” switch on the steering wheel several times to
select the energy monitor display.

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 (traction motor) are on the ground when towing, the
motor may continue to generate electricity. This may cause an electricity leakage
leading to a fire. (
P. 5 2 3 )
●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.

■Active head restraints
■When the active head restraint has been operated
If the active head restraint has been operated, you will not be able to return it to its
original position.
After operation, contact your Lexus dealer.
CAUTION
■Reclining adjustment
Do not recline the seat more than necessary when the vehicle is in motion, to
reduce the risk of sliding under the lap belt.
If the seat is too reclined, during an accident the lap belt may slide past the hips and
apply restraint forces directly to the abdomen or your neck may contact the shoul-
der belt, increasing the risk of death or serious injury.
Adjustments should not be made while driving as the seat may unexpectedly move
and cause the driver to lose control of the vehicle.
Even small forces applied to the seatback
may cause the head restraint to move.During

Driving position memory system
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 front passenger’s seat to be memorized. (if equipped)
■Entering a position to memory
Turn the “POWER” switch to ON mode.
Adjust the driver’s seat, steering wheel, and outside rear view
mirrors to the desired positions.
While pushing the “SET” but-
ton, or within 3 seconds after
the “SET” button is pushed,
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
overwritten.
