■Auto return function when entering the vehicle (driver’s seat only)
When either of the following actions has been performed, the steering
wheel will move toward the driver and seat will move forward: • The power switch has been turned to ACCESSORY mode.
• The driver’s seat belt has been fastened.
■When driving position memory is linked with door unlock operation
If the driver’s door is opened, the driver’s seat will move toward the memorized posi-
tion but stop slightly beforehand to allow easy access to the vehicle.
Turning the power switch to ACCESSORY or ON mode, or fastening the driver’s
seat belt moves the seat fully into the memorized position.
■Operating the driving position memory after turning the power switch off

Memorized positions can be activated up to 180 seconds after the front passenger’s
door is opened by pressing button “1”, “2” or “3”.
■Correct seat position
When the seat is in the most forward or most backward position, and the seat is
being moved in those directions, the system may not correctly recognize the current
position and the memorized positi on will not be correctly recalled.
■The auto away function for exiting the driver’s seat
If the seat is already close to the rearmost position, the auto away function may not
operate when the driver exits the vehicle.
■Customization
The distance that the driver’s seat moves backward during the auto away function
can be changed. (Customizable features: →P. 807)
CAUTION
■Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passen-
ger or squeeze your body against the steering wheel.

Brake Hold
Turns the brake hold system on
The brake hold standby indicator
(green) comes on. While the system is
holding the brake, the brake hold
operated indicator (yellow) comes on.
■Brake hold system operating conditions
The brake hold system cannot be turned on in the following conditions:
●The trunk or hood is not closed.
●The driver’s door is not closed.
●The driver is not wearing the seat belt.
If any of the conditions above are detected when the brake hold system is enabled,
the system will turn off and the brake hold standby indicator light will go off. In addi-
tion, if any of the conditions are detected while the system is holding the brake, a
warning buzzer will sound and a message will be shown on the multi-information dis-
play. The parking brake will then be set automatically.
■Brake hold function
●If the brake pedal is left released for a period of about 3 minutes after the system
has started holding the brake, the parking brake will be set automatically. In this
case, a warning buzzer sounds and a message is shown on the multi-information
display.
●To turn the system off while the system is holding the brake, firmly depress the
brake pedal and press the button again.
●The brake hold function may not hold the vehicle when the vehicle is on a steep
incline. In this situation, it may be necessary for the driver to apply the brakes. The
multi-information display will inform the driver of this situation.
The brake hold system keeps the brak e applied when the shift lever is in
D, S or N with the system on and the brake pedal has been depressed to
stop the vehicle. The system releases the brake when the accelerator
pedal is depressed with the shift lever in D or S to allow smooth start off.

PCS (Pre-Collision System)∗
◆Pre-collision seat belts (front seat only)
If the pre-collision sensor detects that a collision is unavoidable, the
pre-collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (→P. 3 4 )
◆Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed.
◆Pre-collision braking
When there is a high possibility of a frontal collision, the system warns
the driver using a warning light, warning display and buzzer. If the sys-
tem determines that a collision is unavoidable, the brakes are automati-
cally applied to reduce the collision speed.
∗
: If equipped
When the radar sensor detects that a frontal collision is highly likely or
even unavoidable, safety systems such as the brakes and seat belts are
automatically engaged to lessen impact as well as vehicle damage.
The pre-collision system can be turned on and off as necessary by oper-
ating the switch. ( →P. 2 9 7 )

4-5. Using the driving support systems
■Conditions that may trigger the system even if there is no danger of a collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface
●When passing an oncoming vehicle on a left-turn
●When your vehicle rapidly closes on the vehicle in front
●When a grade separation/interchange, sign, billboard, or other structure appears
to be directly in the vehicle’s line of travel
●When climbing a steep hill causes an overhead billboard or other metallic structure
to appear directly in the vehicle’s line of travel
When the system is activated in the situations described above, there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten it.
■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be
occasions when the sensor cannot detect pedestrians, animals, bicycles, motorcy-
cles, trees, or snowdrifts.
■Situations in which the pre-collision system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of your vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●When your vehicle is skidding such as the VSC system off

Maintenance and care
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlapping circles. Do not use water. Wipe dirty sur-
faces and let them dry. Excellent results are obtained by keeping the carpet as dry as
possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
■When cleaning the carpeted portions of the glove box, console box, etc.
If a strong adhesive tape is used, there is a possibility that the surface of the carpet
could be damaged.
CAUTION
■Wa t e r i n t h e v e h i c l e
●Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid bat-
tery (traction battery) air vents, and in the trunk.
Doing so may cause the hybrid battery, electrical components, etc. to malfunc-
tion or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(→ P. 4 0 )
An electrical malfunction may cause the airbags to deploy or not function prop-
erly, resulting in death or serious injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off the
windshield, obstructing the driver’s view and leading to an accident, resulting in
death or serious injury.
