4-2. Driving procedures
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.

4-3. Operating the lights and wipers
■Daytime running light system
●To make your vehicle more visible to other drivers, the parking lights turn on auto-
matically (at an increased intensity) whenever the hybrid system is started and the
parking brake is released. Daytime running lights are not designed for use at night.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel econ-
omy.
■Headlight control sensor
■Automatic light off system
When the light switch is in : The headlights and tail lights turn off 30 seconds
after the power switch is turned to ACCESSORY mode or turned off and a door is
opened and all of the doors and trunk are closed. (The lights turn off immediately if on the key is pressed twice after all the doors are closed.)
To turn the lights on again, turn the power switch to ON mode, or turn the light
switch off once and then back to or .
If any of the doors or trunk lid is kept open, the lights automatically turn off after 20
minutes.
■Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCESSORY
mode and the driver’s door is opened while the lights are turned on.
■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of pas-
sengers and the loading condition of the vehi cle to ensure that the headlights do not
interfere with other road users. The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

Driving
CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (→P. 242) will not be activated, and a fatal or serious accident
may result.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane
■Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the following conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a fatal or serious accident may
result:
●When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the trunk etc.)
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable

Driving
CAUTION
■When using the rear view monitor system
When backing up, be sure to check visually behind and all around the vehicle
before proceeding.
Observe the following precautions to avoid an accident that could result in death
or serious injuries.
●The rear view monitor system is a supplemental device intended to assist the
driver when backing up. Never depend on the rear view monitor system entirely
when backing up. Always make sure your intended path is clear.
Use caution, just as you would when backing up any vehicle.
●Never back up while looking only at the screen.
The image shown on the screen may differ from the actual state, and you could
collide with another vehicle or obstacles if backing up looking only at the screen,
possibly causing an accident. When backing up, be sure to check in front of and
behind the vehicle, both directly and with mirrors.
●Be sure to back up slowly, depressing the brake pedal to control vehicle speed.
●The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traffic con-
ditions, road surface conditions, vehicle condition, etc. when parking. It is neces-
sary to be fully aware of this before using the rear view monitor system.
●When parking, be sure to check that the parking space will accommodate your
vehicle before maneuvering into it.
●Do not use system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire
• When the trunk lid is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
●In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is moving, or you may become unable to
see the image on the screen. Be sure to check direct visually and with mirror all
around the vehicle before proceeding.
●If the tire sizes are changed, the position of the fixation guide lines displayed on
the screen may change.
●The camera uses a special lens. The distances between objects and pedestrians
that appear in the image displayed on the screen will differ from the actual dis-
tances. (→P. 277)

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.
