Accessories, spare parts and modification of your Lexus
A wide variety of non-genuine spare parts and accessories for Lexus vehicles are
currently available in the market. You should know that Toyota does not warrant
these products and is not responsible for their performance, repair, or replacement,
or for any damage they may cause to, or adverse effect they may have on, your
Lexus vehicle.
This vehicle should not be modified with non-genuine Lexus products. Modification
with non-genuine Lexus products could affect its performance, safety or durability,
and may even violate governmental regula tions. In addition, damage or perfor-
mance problems resulting from the modi fication may not be covered under war-
ranty.
Installation of a mobile two-way radio system
As the installation of a mobile two-way ra dio system in your vehicle could affect
electronic systems such as the hybrid system, multiport fuel injection system/
sequential multiport fuel injection system , cruise control system, vehicle dynamics
integrated management, SRS airbag system and seat belt pretensioner system, be
sure to check with your Lexus dealer for precautionary measures or special instruc-
tions regarding installation.
High voltage parts and cables on the hybr id vehicles emit approximately the same
amount of electromagnetic waves as the conventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.

1-1. Hybrid system
■Charging the battery
●As the gasoline engine charges the hybrid battery (traction battery), the battery
does not need to be charged from an outside source. However, if the vehicle is
left parked for a long time the hybrid battery will slowly discharge. For this rea-
son, be sure to drive the vehicle at least once every few months for at least 30
minutes or 10 miles (16 km). If the hybrid battery becomes fully discharged and
you are unable to jump-start the vehicle with the 12 volt battery, contact your
Lexus dealer.
●If the shift lever is in “N”, the hybrid battery (traction battery) will not be
charged. When driving in heavy traffic, operate the vehicle with the shift lever in
“D” or “S” to avoid discharging the battery.
■After the 12 volt battery has discharged or has been changed or removed
The gasoline engine may not st op even if the vehicle is running on the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibrat ion even though the vehicle is able to
move. Always put the shift lever in “P” when parked.
The following sounds or vibrations may occu r when the hybrid system is operating,
and are not a malfunction.
●Motor sounds may be heard fr om the engine compartment.
●Sounds may be heard from the hybrid ba ttery (traction battery) behind the rear
seat when the hybrid system starts or stops.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transmissi on when the hybrid system starts or
stops.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard from the regenerative brake when you press the brake
pedal.
●Vibration may be felt when the gasoline engine starts or stops.
●You may hear cooling fan sounds coming from the air intake vents behind the
rear seat.
■Maintenance, repair, recycling, and disposal
Contact your Lexus dealer regarding main tenance, repair, recycling and disposal.
Do not dispose of the vehicle yourself.

Windshield wipers and washer
■The windshield wiper and washer can be operated when
The power switch is in “IG-ON” mode.
■Dripping prevention wiper sweep
After washing and wiping operation several times, the wipers operate one more
time after a short delay to prevent dripping.
However, the last sweep will not happen if the vehicle is traveling above 106 mph
(170 km/h).
■Effects of vehicle speed on wiper operation
With the settings other than “AUTO” also, the time until drip prevention wiper
sweep occurs is changed depending on vehicle speed.
With “LO” selected, wiper operation will be switched from low speed to intermit-
tent wiper operation only when the vehicle is stationary.
■ Rain-sensing windshield wipers
With “AUTO” selected, the wipers will operate automatically when
the sensor detects falling rain. The system automatically adjusts

When driving
Beeps and obstacle distanceA beep sounds when an obstacle with which there is a danger of collision
is detected. As the vehicle moves clos er to the obstacle, the interval of
the beep becomes shorter.
● When the following obstacle distan ces are reached, the beep changes
from intermittent to continuous:
• If the distance to the obstacle detected by the dual sensors or rear corner
sensors is less than 0.8 ft. (25 cm).
• If the distance to the obstacle detected by the back sensors is less than 1.1
ft. (35 cm).
● If obstacles are detected by the dual sensors in 2 places at once, or if
both rear corner sensors detect obst acles at the same time, the system
will sound a warning beep for the closer of the 2 obstacles.
● If multiple obstacles are detected in front and behind the vehicle at the
same time, the warning beep will change in the following manner:
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected near a different area of th e vehicle, the warning beep will sound
6 beeps then one continuous beep.
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected within 0.8 ft. (25 cm) of a different area of the vehicle, the warn-
ing beeps will sound 2 beeps then one continuous beep.
●You can change the volume of the warning beeps. (P. 155)

2-4. Using other driving systems
■The intuitive parking assist can be operated when
The power switch is in the “IG-ON” mode.
■When the system malfunctions
●If a malfunction occurs and no obstacles have been detected, a warning is dis-
played, and a malfunction beep sounds for 7 seconds.
If an obstacle has been detected, or another malfunction occurs in a different
sensor, the malfunction beeps will not sound.
●In the following circumstances the displayed warning will disappear:
• If you switch the screen to a different mode.
• If you turn OFF the intuitive parking assist main switch.
• If the vehicle speed exceeds 6 mph (10 km/h). Once the vehicle speed drops
below 6 mph (10 km/h), the warning will be displayed again.
●If the malfunction screen is displayed, the detection range of the dual sensors is
shortened. In this case, the necessity fo r obstacle evasion (whether the obstacle
will come within 0.8 ft. [25 cm] of the vehicle or not) will not be calculated.
■When using intuitive parking assist
●The sensors' detection areas and reaction times are limited. When moving for-
ward 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.
• The sensors' detection areas are limited to the areas around the vehicle’s front
and rear bumpers.
• Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or dete ction may be impossible.
• There will be a short delay between ob stacle detection and display. Even at
slow speeds, there is a possibility that the obstacle will come within 0.8 ft. (25
cm) of the vehicle before the display is shown and the warning beep sounds.
• Braking distance may differ according to the road conditions (rain, gravel etc.).
• It might be difficult to hear beeps due to the volume of audio system or air flow noise of air conditioning system.
• For long obstacles such as walls, the obstacle warning may change as the
obstacle gets closer.
