nCustomization that can be configured at Lexus dealer
Settings (e.g. buzzer volume) can be changed. (Customizable features →P. 4 6 1 )
CAUTION
nCaution when using the intuitive parking sensor
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and possi-
bly cause an accident.
lDo not use the sensor at speeds in excess of 6 mph (10 km/h).
lDo not attach any accessories within the sensor range.
NOTICE
nNotes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

PCS (Pre-Collision System)∗
Radar sensor
Detects vehicles or other obsta-
cles on or near the road ahead and
determines whether a collision is
imminent based on the position,
speed, and heading of the obsta-
cles.
Grille cover
Radar sensor
Safety systems such as the brakes and seat belts are automatically
engaged to lessen impact and injuries to occupants as well as vehicle dam-
age when the radar sensor detects an unavoidable frontal collision.
nPre-collision seat belts
The seat belts are immediately retracted to provide the driver and passen-
gers with enhanced pretensioner effectiveness in a collision. (→P. 5 7 ) I n
the event of sudden braking or skidding, the system will operate even if no
obstacle has been detected.
nPre-collision brake assist
Applies greater braking force in relation to how strongly the brake pedal is
depressed.
nObstacles not detected
The sensor cannot detect plastic obstacles such as pylons. There may also be occa-
sions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles,
trees, or snowdrifts.

When driving
CAUTION
nLimitations of the pre-collision system
Do not rely on the pre-collision system. Always drive safely, taking care to observe
your surroundings and checking for any obstacles or other road hazards.
nHandling the radar sensor
Observe the following to ensure the pre-collision system can function effectively.
lKeep the sensor and front grille clean at all times.
Clean the sensor and front grille with a soft cloth so you do not mark or damage
them.
lDo not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction. If the
sensor or surrounding area are subject to a strong impact, always have the area
inspected and adjusted by a Lexus dealer.
lDo not disassemble the sensor.
lDo not attach accessories or stickers to the sensor, grille guard or surrounding
area.

When driving
NOTICE
nRepairing or replacing snow tires
Request repairs of and obtain replacement snow tires from Lexus dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the operation of
the tire air pressure sensor.
nFitting tire chains
The tire air pressure sensor may not function correctly when tire chains are fitted.

CAUTION
nWhile driving the vehicle
Do not adjust the display. Be sure to adjust the display only when the vehicle is
stopped.
nWhen doing the circling calibration
Be sure to secure a wide space, and watch out for people and vehicles in the neigh-
borhood. Do not violate any local traffic rules while performing circling calibration.
NOTICE
nTo avoid the compass malfunctions
Do not place magnets or any metal objects near the inside rear view mirror.
Doing this may cause a malfunction of the compass sensor.
nTo ensure normal operation of the compass
lDo not perform circling calibration of the compass in a place where the earth's
magnetic field is subject to interference by artificial magnetic fields.
lDuring calibration, do not operate electric systems (moon roof, power windows,
etc.) as they may interfere with the calibration.

5-1. Essential information
Event data recorder
In a crash or a near car crash event
The SRS airbag sensor assembly contains the EDR. In a crash or a near
car crash event, this device may record some or all of the following infor-
mation:
lEngine speed
lWhether the brake pedal was applied or not
lVehicle speed
lTo what extent the accelerator pedal was depressed
lPosition of the transmission shift lever
lWhether the driver and front passenger wore seat belts or not
lDriver's seat position
lSRS airbag deployment data
lSRS airbag system diagnostic data
lFront passenger’s occupant classification
The information above is intended to be used for the purpose of improv-
ing vehicle safety performance. Unlike general data recorders, the EDR
does not record sound data such as conversation between passengers.
Your vehicle has computers that monitor and control certain aspects of
your vehicle. These computers assist in driving and maintaining optimal
vehicle performance.
Besides storing data useful for troubleshooting, there is an event data
recorder (EDR) that records data in a crash or a near car crash event.

5-2. Steps to take in an emergency
nIf the malfunction indicator lamp comes on while driving
First check the following:
lIs the fuel empty?
If it is, fill the fuel tank immediately.
lIs the fuel tank cap loose?
If it is, tighten it securely.
The lamp will go off after taking several driving trips.
If the lamp does not go off even after several trips, contact your Lexus dealer as
soon as possible.
nElectric power steering warning light
When the battery is low or when the voltage drops temporarily, the electric power
steering warning light may come on.
nFront passenger detection sensor and passenger seat belt reminder and warning
buzzer
lIf luggage is placed on the front passenger seat, the front passenger detection
sensor may cause the warning light to flash and the warning buzzer to sound,
even if a passenger is not sitting in the seat.
lIf a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
nWhen the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pressing the
satellite switch does not turn off the tire pressure warning light.
nThe tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such as natural air
leaks or tire inflation pressure changes caused by temperature. In this case, adjust-
ing the tire inflation pressure will turn off the warning light (after a few minutes).
nWhen a tires is replaced with a spare tire
The compact spare tire is not equipped with the tire pressure warning valve and
transmitter. If a tire goes flat, the tire pressure warning light will not turn off even
though the flat tire is replaced with the spare tire. Replace the spare tire with the
repaired tire and adjust the proper tire inflation pressure. The tire pressure warning
light will turn off after a few minutes.
