*1: These lights turn on when the “START STOP ENGINE” <“POWER”> switch isturned to IGNITION ON mode to indicate that a system check is being
performed. They will turn off after the engi ne is on, or after a few
seconds. There may be a malfunction in a system if the lights do not turn on, or
turn off. Have the vehicle inspected by your Lexus dealer.
*2: The light flashes to indicate that the system is operating.
*3: The light turns on when the system is turn ed off. The light flashes quickly to indi-
cate that the system is operating.
*4: In order to confirm operation, the BSM outside rear view mirror indicators illumi-
nate in the following situations:
• When the “START STOP ENGINE” <“POWER”> switch is turned to IGNI- TION ON mode while the BSM main switch is set to ON.
• When the BSM main switch is set to ON while the “START STOP ENGINE”
<“POWER”> switch is in IGNITION ON mode.
If the system is functioning correctly, the BSM outside rear view mirror indicators
will turn off after a few seconds.
If the BSM outside rear view mirror indicato rs do not illuminate or do not turn off,
there may be a malfunction with the system. If this occurs, have the vehicle
inspected by your Lexus dealer.
CAUTION
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on
when you start the engine , this could mean that these systems are
not available to help protect you in an accident, which could result in death or seri-
ous injury. Have the vehicle inspected by your Lexus dealer immediately if this
occurs.

■Setting display automatic cancelation
In the following situations, setting display in which the settings can be changed
through the “DISP” button will automatically be turned off.
●When a warning message appears whil e the setting display is displayed
●When the vehicle begins to move while the setting display is displayed
■Tire inflation pressure
●It may take a few minutes to display the tire inflation pressure after the “START
STOP ENGINE” <“POWER”> switch is tu rned to IGNITION ON mode. It
may also take a few minutes to display the tire inflation pressure after inflation pres-
sure has been adjusted.
●“---” may be displayed if the tire position information cannot be determined due to
unfavorable radio wave conditions.
●Tire inflation pressure changes with temperature. The displayed values may also be
different from the values measured using a tire pressure gauge.
■Liquid crystal display
Small spots or light spots may appear on th e display. This phenomenon is character-
istic of liquid crystal displays, and there is no problem continuing to use the display.
■Customization
Setting of available languages can be changed. (Custo mizable features P. 7 3 0 )

■Conditions in which the function may not operate correctly
In the following conditions, the camera sensor may be unable to recognize lane
markers causing the lane departure warning function to operate incorrectly. How-
ever, this does not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a crossing
or before a ticket checkpoint
●When driving on a sharp curve
●When lane markers are extremely narrow or extremely wide
●When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is
extremely short
●When the lane markers are yellow (These may be more difficult for the system to
recognize compared to white markers.)
●When the lane markers are broken, “Botts’ dots”, “Raised pavement marker” or
stones
●When the lane markers are on a curb etc.
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a
shadow covers the lane markers
●When driving on a particularly bright road surface, such as concrete
●When driving on a road surface that is bright due to reflected light
●When driving in a location where the light level changes rapidly, such as the
entrance to or exit from a tunnel
●When sunlight or the headlights of oncoming vehicles are shining directly into the
camera lens
●When driving on roads that are branching or merging
●When driving on a road surface that is wet due to rain, previous rainfall, standing
water, etc.
●When the vehicle experiences strong up-a nd-down motion such as when driving
on an extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or
when the headlights are misaligned
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads

PCS (Pre-Collision System)
◆Pre-collision seat belts (front seats only)
If the pre-collision sensor detects that a collision is unavoidable, the
pre-collision system will retract the seat belt before the collision occurs.
The same will happen if the dr iver makes an emergency braking or
loses control of the vehicle. ( P. 3 4 )
However, when the VSC system is disa bled, the system will not operate
in the event of skidding.
◆Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed.
◆Pre-collision braking
When there is a high poss ibility of a frontal collision, the system warns
the driver using a warning light, war ning display and buzzer. If the sys-
tem determines that a collision is unavoidable, the brakes are automati-
cally applied to reduce the collision speed.

: If equipped
When the radar sensor detects possibility of a frontal collision, the pre-
collision system such as the brakes and seat belts are automatically
engaged to lessen impact as well as vehicle damage.
The pre-collision system ca n be turned on and off as necessary by oper-
ating the switch. ( P. 322)

Enabled
Disabled
The “PCS” warning light turns on
when pre-collision system is disabled.
The radar sensor detects vehicles or
other obstacles on or near the road
ahead and determines whether a
collision is imminent based on the
position, speed, and heading of the
obstacles.

■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the sen-
sors being unable to detect obstacles, the pre-collision system will be automatically
disabled. In this case, the system will not activate even if there is a collision possibility.
■When there is a malfunction in the system, or if the system is temporarily unusable
“PCS” warning light will flash and warning messages will be displayed.

Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses tire
pressure warning valves and transmitters to detect low tire inflation pres-
sure before serious problems arise.
●If the tire pressure drops below a predetermined level, the driver is
warned by a screen display and a warning light. (P. 650)
●The tire pressure detected by the tire pressure warning system can be
displayed on the multi- information display. (P. 105)
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new ID codes must be registered in the tire pressure warning computer
and the tire pressure warning system must be initialized. Have tire pres-
sure warning valve and transmitter ID codes registered by your Lexus
dealer. ( P. 569)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following
circumstances:
●When rotating the tires.
●When the tire inflation pressure is changed such as when changing
traveling speed or load weight.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.

■How to initialize the tire pressure warning systemPark the vehicle in a safe place and turn the “START STOP
ENGINE” <“POWER”> switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 712)
Make sure to adjust the tire pressure to the specified cold tire inflation pres-
sure level. The tire pressure warning sy stem will operate based on this pressure
level.
Turn the “START STOP ENGINE” <“POWER”> switch to
IGNITION ON mode.
Press and hold the tire pres-
sure warning reset switch until
the tire pressure warning light
blinks slowly 3 times.
Wait for a few minutes with the “START STOP ENGINE”
<“POWER”> switch in IGNITION ON mode and then turn
the “START STOP ENGINE” <“POWER”> switch off.
