Before driving
You can replace the battery by yourself
( P.368). However, as there is a danger
that the electronic key may be damaged, it
is recommended that replacement be car-
ried out by your Lexus dealer.
●To avoid serious deterioration, do not
leave the electronic key within 3 ft. (1 m)
of the following electr ical appliances that
produce a magnetic field:
• TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
■Replacing the battery
 P.368
■Confirmation of the registered key
number
The number of keys already registered to
the vehicle can be confirmed. Ask your
Lexus dealer for details.
■If “A New Key has been Registered
Contact Your Dealer for Details” is
shown on the multi-information display
This message will be displayed each time
the driver’s door is opened when the doors
are unlocked from the outside for approxi-
mately 10 days after a new electronic key
has been registered. If this message is dis-
played but you have not had a new elec-
tronic key registered, ask your Lexus dealer
to check if an unknown electronic key
(other than those in your possession) has
been registered.
NOTICE
■To prevent key damage
●Do not drop the keys, subject them to
strong shocks or bend them.
●Do not expose the keys to high tem-
peratures for long periods of time.
●Do not get the keys wet or wash them
in an ultrasonic washer, etc.
●Do not attach metallic or magnetic
materials to the keys or place the keys
close to such materials.
●Do not disassemble the keys.
●Do not attach a sticker or anything else
to the surface of the electronic key.
●Do not place the keys near objects that
produce magnetic fields, such as TVs,
audio systems and induction cookers,
or medical electrical equipment, such
as low-frequency therapy equipment.
■Carrying the electronic key on your
person
Carry the electronic key 3.9 in. (10 cm)
or more away from electric appliances
that are turned on. Radio waves emitted
from electric applianc es within 3.9 in. (10
cm) of the electronic key may interfere
with the key, causing the key to not func-
tion properly.
■In case of a smart access system with
push-button start malfunction or
other key-related problems
 P.403
■When an electronic key is lost
 P.402
■Handling the card key
●If the battery or card key terminals get
wet, the battery may corrode and the
card key may stop working.
If the key is dropped into water, or if
drinking water, etc., is spilled on the
key, immediately remove the battery
cover and wipe the battery and termi-
nals. (To remove the battery cover,
lightly grasp and pull it.) If the battery is
corroded, have your Lexus dealer
replace the battery.
●Do not crush the battery cover or use
a screwdriver to remove the battery
cover.
Forcibly removing the battery cover
may bend or damage the key.

■Raindrop sensor (vehicles with rain-
sensing windshield wipers)
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not

or lower, automatic operation may not
occur. In this case, operate the wipers in
any mode other than AUTO mode.

the windshield is subject to vibration in
AUTO mode. Take care that your fingers,
etc. do not become caught in the wind-
shield wipers.
■Caution regarding the use of washer
fluid
When it is cold, do not use the washer
fluid until the windshield becomes warm.
The fluid may freeze on the windshield
and cause low visibility. This may lead to
an accident, resulting in death or serious
injury.
NOTICE

Do not operate the switch continually as
the washer fluid pump may overheat.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other
object. The nozzle will be damaged.

2344-5. Using the driving support systems
■The system can be operated when
●The power switch is in ON.
●Intuitive parking assist function is on.
●The vehicle speed is less than about 6
mph (10 km/h).
●The shift lever is in a position other than P.
■Setting the buzzer volume
The buzzer volume can be adjusted on the
multi-information display. ( P.231)
■If “Parking Assist Unavailable Clean
Parking Assist Sensor” is displayed on
the multi-information display
A sensor may be covered with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low
temperatures, a warning message may be
displayed or the sensor may not be able to
detect an object. Once the ice melts, the
system will return to normal.
■Sensor detection information
●The sensor’s detectio n areas are limited
to the areas around the vehicle’s front and
rear bumpers.
WARNING
●The sensors’ detection areas and reac-
tion times are limited. When moving
forward or reversing, check the areas
surrounding the vehicle (especially the
sides of the vehicle) for safety, and
drive slowly, using the brake to control
the vehicle’s speed.
●Do not install accessories within the
sensors’ detection areas.
●The area directly under the bumpers is
not detected.
■When to disable the function
In the following situations, disable the
function as it may operate even though
there is no possibility of a collision.
●The vehicle is equipped with a fender
pole or wireless antenna.
●The front or rear bu mper or a sensor
receives a strong impact.
●A non-genuine Lexus suspension
(lowered suspension, etc.) is installed.
●Towing eyelet is installed.
●A backlit license plate is installed.
■When using intuitive parking assist
In the following situations, the system
may not function correctly due to a sen-
sor malfunction, etc. Have the vehicle
checked by your Lexus dealer.
●The intuitive parking assist operation
display flashes or shows continuously,
and a beep sounds when no objects
are detected.
●If the area around a sensor collides
with something, or is subjected to
strong impact.
●If the bumper or grille collides with
something.
●If the display flashes or is displayed
continuously and a buzzer does not
sound, except when the mute function
has been turned on.
●If a display error oc curs, first check the
sensor.
If the error occurs even when there is
no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or
steam to the sensor area.
Doing so may result in the sensor mal-
functioning.
●When using a high pressure washer to
wash the vehicle, do not spray the sen-
sors directly, as doing so may cause a
sensor to malfunction.
●When using steam to clean the vehicle,
do not direct steam too close to the
sensors as doing so may cause a sen-
sor to malfunction.
