Pre-collision braking
The system may not operate in the following situations: ●
If a battery terminal has been disconnected and reconnected and then the vehicle has not
been driven for a certain amount of time●
If the shift position is in R●
When the VSC OFF indicator is illuminated (only the pre-collision warning function will
be operational)■
Object detection function
The system detects ob jects based on their
size, profile, motion, etc. However, an object
may not be detected depending on the sur-
rounding brightness and the motion, pos-
ture, and angle of the detected object,
preventing the system from operating prop-
erly. (  P.220)
The illustration shows an image of detect-
able objects.
■
Cancelation of the pre-collision braking
If either of the following occur while the
pre-collision braking function is operating, it
will be canceled:
●
The accelerator pedal is depressed
strongly.
●
The steering wheel is turned sharply or
abruptly.
■
Conditions under which the system may
operate even if there is no possibility of a
collision
●
In some situations such as the following,
the system may determine that there is a possibility of a frontal collision and oper-
ate.
• When passing a detectable object, etc.
• When changing lanes while overtaking a
detectable object, etc.
• When approaching a detectable object
in an adjacent lane or on the roadside,
such as when changing the course of
travel or driving on a winding road
• When rapidly closing on a detectable
object, etc.
• When approaching objects on the road-
side, such as detectable objects, guard-
rails, utility poles, trees, or walls
• When there is detectable object or other
object by the roadside at the entrance of
a curveDetectable objects Vehicle speed Relative speed between your
vehicle and object

Example: Multi-information display:
“BRAKE!”
Example: Multi-information display: “Switch to Brake” ■
If the Parking Support Brake has oper-
ated
If the vehicle is stopped due to operation of
the Parking Support Brake, the Parking
Support Brake will be disabled and the
PKSB OFF indicator will illuminate. If the
Parking Support Brake operates unneces-
sarily, brake control can be canceled by
depressing the brake pedal or waiting for
approximately 2 seconds for it to automati-
cally be canceled. Then, the vehicle can be
operated by depressing the accelerator
pedal. ■
If “Parking Support Brake Unavailable”
is displayed on th e multi-information
display and the PKSB OFF indicator is
flashing
If the vehicle is stopped due to operation of
the Parking Support Brake, the Parking
Support Brake will be disabled and the
PKSB OFF indicator will illuminate. ●
A sensor may be cove red with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to
normal.
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 wi ll return to normal.●
If this message is di splayed only when the
R shift position is selected, the rear cam-
era lens may be dirty. Clean the camera
lens. If this message is displayed in any
forward shift position, a sensor on the
front or rear bumper may be dirty. Clean
the sensors and their surrounding area
on the bumpers. ●
If this message continues to be displayed
even after cleaning the sensor, or is dis-
played even though the sensor is clean,
have the vehicle inspected by your Lexus
dealer. ●
Initialization may not have been per-
formed after a battery terminal was dis-
connected and reconnected. Initialize the
system. (  P.274)
If this message continues to be displayed
even after initializati on, have the vehicle
inspected by your Lexus dealer.
■
If a battery terminal has been discon-
nected and reconnected
The system needs to be initialized. To initial-
ize the system, drive the vehicle straight
ahead for 5 seconds or more at a speed of
approximately 22 mph (35 km/h) or more. D

Driving of the following situations: ●
Shift the shift position to P or N●
The accelerator pedal is depressed●
The parking brake is engaged●
2 seconds at maximum elapsed after the
brake pedal is released■
VGRS is disabled when
VGRS may stop operating in the following
situations.
In this event, the steering wheel may move
from its straight forward position, but it will
return when the system restarts. ●
When the steering wheel is operated for
an extended period of time while the
vehicle is stopped or is moving very
slowly (on vehicles with LDH, DRS is dis-
abled together with VGRS)●
When the steering wheel has been held
fully to the left or right
The center position of the steering wheel
may change when VGRS is disabled. How-
ever, the position will return to normal after
VGRS is reactivated. ■
When the battery is disconnected (vehi-
cles with VGRS)
The steering wheel may move from its
straight forward position, but this will be
corrected automatically when driving. ■
Sounds and vibrations caused by the
ABS, brake assist, VS C, TRAC, hill-start
assist control and VGRS systems●
A sound may be heard from the engine
compartment when the brake pedal is
depressed repeatedly, when the engine is
started or just after the vehicle begins to
move. This sound does not indicate that a
malfunction has occurred in any of these
systems.
●
Any of the following conditions may
occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehicle
body and steering.
• A motor sound may be heard also after
the vehicle comes to a stop.
• Vehicles without Lexus Safety System +
A: The brake pedal may pulsate slightly after the ABS is activated.
• Vehicles without Lexus Safety System +
A: The brake pedal may move down
slightly after the ABS is activated.■
ECB operating sound
ECB operating sound may be heard in the
following cases, but it does not indicate that
a malfunction has occurred. ●
Operating sound heard from the engine
compartment when the brake pedal is
operated. ●
Motor sound of the brake system heard
from the front part of the vehicle when
the driver’s door is opened. ●
Operating sound heard from the engine
compartment when one or two minutes
passed after the stop of the engine. ■
EPS, VGRS and DRS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunction. ■
Automatic reactivation of TRAC and
VSC systems
After turning the TRAC and VSC systems
off, the systems will be automatically
re-enabled in the following situations: ●
When the engine switch is turned off ●
If only the TRAC system is turned off, the
TRAC will turn on when vehicle speed
increases
If both the TRAC and VSC systems are
turned off, automatic re-enabling will not
occur when vehicle speed increases. ■
Reduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is
reduced to prevent the system from over-
heating when there is frequent steering
input over an extended period of time. The
steering wheel may feel heavy as a result.
Should this occur, re frain from excessive
steering input or stop the vehicle and turn
the engine off. The EPS system should
return to normal within 10 minutes.
■
Secondary Collision Brake operating
conditions
The vehicle speed is approximately 6 mph
