the engine switch <power switch> has
been turned to ACCESSORY or
IGNITION ON mode <ON mode> to
indicate that the system has been can-
celed.
■System maintenance
The vehicle has a maintenance-free type
engine immobilizer system <immobilizer system>.
■Conditions that may cause the system to malfunction
●If the grip portion of the key is in contact with a metallic object
●If the key is in close proximity to or touch-ing a key registered to the security sys-
tem (key with a built-in transponder chip) of another vehicle
Engine immobilizer system
<Immobilizer system>
The vehicle’s keys have built-in tran-
sponder chips that prevent the
engine <hybrid system> from start-
ing if a key has not been previously
registered in the vehicle’s on-board
computer.
Never leave the keys inside the
vehicle when you leave the vehicle.
This system is designed to help pre-
vent vehicle theft but does not guar-
antee absolute security against all
vehicle thefts.

■The intrusion sensor and tilt sensor
detection
 The intrusion sensor detects intrud-
ers or movement in the vehicle.
 The tilt sensor detects changes in
vehicle inclination, such as when the
vehicle is towed away.
This system is designed to deter and
prevent vehicle theft but does not
guarantee absolute security against all
intrusions.
■Setting the intrusion sensor and tilt
sensor
The intrusion sensor and tilt sensor will
be set automatically when the alarm is
set. ( P.77)
■Canceling the intrusion sensor and
tilt sensor
If you are leaving pets or other moving
things inside the vehicle, make sure to
disable the intrusion sensor and tilt
sensor before setting the alarm, as they
will respond to movement inside the
vehicle.
1 Turn the engine switch <power
switch> off.
2 Press the intrusion sensor and tilt
sensor cancel switch.
Press the switch again to re-enable the intrusion sensor and tilt sensor.
Each time the intrusion sensor and tilt sen- sor are canceled/set, a message will be shown on the multi-information display in
the instrument cluster.
■Canceling and automatic re-enabling of
the intrusion sensor and tilt sensor
●The alarm will still be set even when the
intrusion sensor and tilt sensor are can- celed.
●After the intrusion sensor and tilt sensor are canceled, pressing the engine switch <power switch> or unlocking the doors
using the entry function or wireless remote control will re-enable the intru-sion sensor and tilt sensor.
●The intrusion sensor and tilt sensor will automatically be re-enabled when the
alarm system is deactivated.

*: If equipped
■Pre-collision warning
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes-
sage will be displayed on the multi-
information display to urge the driver
to take evasive action.
■Pre-collision brake assist
When the system determines that the
possibility of a frontal collision is high,
the system applies greater braking
force in relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
When the system determines that the
possibility of a frontal collision is high,
the system warns the driver. If the sys-
tem determines that the possibility of a
frontal collision is extremely high, the
brakes are automatically applied to
help avoid the collision or reduce the
collision speed.
■Suspension control
When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension sys-
tem ( P.262) will control the damping
force of the shock absorbers to help
maintain an appropriate vehicle pos-
ture.
■Steering control (if equipped)
When the system determines that the
possibility of a frontal collision is high
PCS (Pre-Collision System)*
The pre-collision system uses a
radar sensor and camera sensor to
detect vehicles and pedestrians*1 in
front of your vehicle. When the sys-
tem determines that the possibility
of a frontal collision with a vehicle
or pedestrian is high, a warning
operates to urge the driver to take
evasive action and the potential
brake pressure is increased to help
the driver avoid the collision. If the
system determines that the possi-
bility of a frontal collision with a
vehicle or pedestrian is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. ( P.212)
*1: Depending on the region in which
the vehicle was sold, the pedestrian
detection function may not be avail-
able. Contact any authorized Lexus
retailer or Lexus authorized repairer,
or any reliable repairer for details.

WARNING
●Assisting the driver to measure follow- ing distance
The dynamic radar cruise control with
full-speed range is on ly intended to help
the driver in determ ining the following
distance between the driver’s own vehi-
cle and a designated vehicle traveling
ahead. It is not a mechanism that allows
careless or inattentive driving, and it is
not a system that can assist the driver in
low-visibility conditions. It is still neces-
sary for driver to pay close attention to
the vehicle’s surroundings.
●Assisting the driver to judge proper following distance
The dynamic radar cruise control with
full-speed range determines whether the
following distance between the driver’s
own vehicle and a designated vehicle
traveling ahead is within a set range. It is
not capable of making any other type of
judgement. Therefore, it is absolutely
necessary for the driver to remain vigi-
lant and to determine whether or not
there is a possibility of danger in any
given situation.
●Assisting the driver to operate the vehicle
The dynamic radar cruise control with
full-speed range has limited capability to
prevent or avoid a collision with a vehicle
traveling ahead. Therefore, if there is
ever any danger, the driver must take
immediate and direct control of the vehi-
cle and act appropriately in order to
ensure the safety of all involved.
■To avoid inadvertent dynamic radar cruise control with full-speed range
activation
Switch the dynamic radar cruise control
with full-speed range off using the cruise control main switch when not in use.
■Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control
with full-speed range in any of the follow- ing situations.
Doing so may result in inappropriate speed control and could cause an acci-dent resulting in death or serious injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those cov- ered with rain, ice or snow
●On steep downhills, or where there
are sudden changes between sharp up and down gradients Vehicle speed may exceed the set
speed when driving down a steep hill.
●At entrances to freeways and highways
●When weather conditions are bad enough that they may prevent the sen-sors from detecting correctly (fog,
snow, sandstorm, heavy rain, etc.)
●When there is rain, snow, etc. on the front surface of the radar sensor or camera sensor
●In traffic conditions that require fre-
quent repeated acceleration and deceleration
●During emergency towing

• When the Lexus parking assist-sensor is turned off once and turned on again• When the engine switch <power switch>
is turned off once and turned to IGNI- TION ON mode <ON mode> again
■If “Clean Parking Assist Sensor” is dis-played on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from
the sensor, the system should return to nor- mal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may appear or an obstacle may not be detected.
If the sensor thaws out, the system should return to normal.
■If “Parking Assist Malfunction” or “Park-ing Assist Malfunction Visit Your
Dealer” is displayed on the multi-infor- mation display
There is a malfunction and the device may not be working properly.
Have the vehicle inspected by any autho- rized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Sensor detection information
●The sensor’s detection areas are limited
to the areas around the vehicle’s front and rear bumpers.
●Certain vehicle conditions and the sur-rounding environment may affect the ability of the sensor to correctly detect
obstacles. Particular instances where this may occur are listed below.• There is dirt, snow or ice on the sensor.
(Wiping the sensors will resolve this problem.)• The sensor is frozen. (Thawing the area
will resolve this problem.)
In especially cold weather, if a sensor is fro-
zen the screen may show an abnormal dis-
play, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.• On an extremely bumpy road, on an
incline, on grav el, or on grass. • The vicinity of the vehicle is noisy due to
vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensor in the vicinity.• The sensor is splashed with water or
heavy rain. • The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed. • The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.• People may not be detected if they are
wearing certain types of clothing.
In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by
the sensor to be closer than they are.
●The shape of the obstacle may prevent the sensor from detecting it. Pay particu-
lar attention to the following obstacles: • Wires, fences, ropes, etc.• Cotton, snow and other materials that
absorb sound waves • Sharply-angled objects•Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your vehicle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impos-
sible. • Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the
obstacle will come within the sensor’s detection areas before the display is shown and the warning beep sounds.

■ECB (Electronically Controlled
Brake System)
The electronically controlled system
generates braking force correspond-
ing to the brake operation
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the
brakes are applied suddenly, or if the
brakes are applied while driving on a
slippery road surface
■Brake assist
Generates an increased level of brak-
ing force after the brake pedal is
depressed when the system detects a
panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding
when swerving suddenly or turning on
slippery road surfaces
■Secondary Collision Brake (if
equipped)
When the airbag sensor detects a colli-
sion, the brakes and brake lights are
automatically controlled to reduce the
vehicle speed and that helps reduce
the possibility of further damage due to
a secondary collision.
■TRC (Traction Control)
Helps to maintain drive power and pre-
vent the drive wheels from spinning
when starting the vehicle or accelerat-
ing on slippery roads
■Hill-start assist control
Helps to reduce the backward move-
ment of the vehicle when starting on an
uphill
■VGRS (Variable Gear Ratio Steer-
ing) (if equipped)
Adjusts the front wheel turning angle in
accordance with the vehicle speed and
steering wheel movement
■DRS (Dynamic Rear Steering) (if
equipped)
Contributes to the turning characteris-
tics and responsiveness of the vehicle
by slightly adjusting the rear wheel
angle of the vehicle in accordance with
steering wheel movement.
■EPS (Electric Power Steering)
Employs an electric motor to reduce
the amount of effort needed to turn the
steering wheel
■AVS (Adaptive Variable Suspen-
sion System)
By independently controlling the
damping force of the shock absorbers
for each of the 4 wheels according to
Driving assist systems
To keep driving safety and perfor-
mance, the following systems oper-
ate automatically in response to
various driving situations. Be aware,
however, that these systems are
supplementary and should not be
relied upon too heavily when oper-
ating the vehicle.
