When the “TRC OFF” indicator comes on even if the TRC OFF switch has not
been pressed
TRC cannot be operated. Contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
A sound may be heard from the engine compartment when the hybrid system is
started, just after the vehicle begins to move, if the brake pedal is depressed
forcefully or repeatedly, or 1-2 minutes after the hybrid system is stopped. 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 operat-
ing. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
Reduced effectiveness of the EPS system
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, refrain from
excessive steering input or stop the vehicle and turn the hybrid system off. The
EPS system should return to normal within 10 minutes.
Automatic reactivation of TRC system
After turning the TRC system off, the system will be automatically re-enabled in
the following situations:
When the power switch is turned off
The TRC will turn on when vehicle speed increases
Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will
operate:
The emergency flashers are off.
Actual vehicle speed is over 55 km/h (35 mph).
The brake pedal is depressed in a manner that cause the system to judge from
the vehicle deceleration that this is a sudden braking operation.
Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
The emergency flashers are turned on.
The brake pedal is released.
The system judges from the vehicle deceleration that is not a sudden braking
operation.

The ABS does not operate effectively when
The limits of tire gripping performance have been exceeded (such as exces-
sively worn tires on a snow covered road).
The vehicle hydroplanes while driving at high speed on wet or slick road.
Stopping distance when the ABS is operating may exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations:
When driving on dirt, gravel or snow-covered roads
When driving with tire chains
When driving over bumps in the road
When driving over roads with potholes or uneven surfaces
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slippery
road surfaces, even if the TRC system is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
When the TRC system is turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the system to help ensure vehicle stability and driving force, do not
turn the TRC system off unless necessary.
Replacing tires
Make sure that all tires are of the specified size and of the same brand, tread
pattern and total load capacity. In addition, make sure that the tires are inflated
to the recommended tire inflation pressure level.
The ABS, VSC and TRC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional for further information when replacing tires or wheels.
Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Hill-start assist control
To engage hill-start assist control,
further depress the brake pedal
when the vehicle is stopped com-
pletely.
A buzzer will sound once to indicate
the system is activated. The slip
indicator will also start flashing.
Hill-start assist control operating conditions
The system operates in the following situations:
• The shift position is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
Hill-start assist control cannot be operated while the slip indicator light is illu-
minated.
Hill-start assist control
While hill-start assist control is operating, the brakes remain automatically
applied after the driver releases the brake pedal. The stop lights and the high
mounted stoplight turn on.
Hill-start assist control operates for about 2 seconds after the brake pedal is
released.
If the slip indicator does not flash and the buzzer does not sound when the brake
pedal is further depressed, slightly reduce the pressure on the brake pedal (do
not allow the vehicle to roll backward) and then firmly depress it again. If the
system still does not operate, check if the operating conditions explained above
have been met.
Assists with starting off and temporarily maintains braking power even if
the foot is removed from the brake pedal when starting off on an incline
or a slippery slope.

PCS (Pre-Crash Safety system)
Pre-crash seat belts (front seat belts only)
If the pre-crash sensor detects that a collision is unavoidable, the pre-
crash safety system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (P. 4 1 )
However, when the VSC system is disabled, the system will not oper-
ate in the event of skidding.
Pre-crash 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-crash braking
When there is a high possibility of a frontal collision, the system warns
the driver using a warning light, warning display and buzzer. If the sys-
tem determines that a collision is unavoidable, the brakes are automati-
cally applied to reduce the collision speed. Pre-crash braking can be
disabled using the pre-crash braking off switch.
: If equipped
When the radar sensor detects possibility of a frontal collision, the pre-
crash safety system such as the brakes and seat belts are automatically
engaged to lessen impact as well as vehicle damage.

When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
When water or snow thrown up by the surrounding vehicles hinders the func-
tioning of the sensor
When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
Vehicles that cut in suddenly
Vehicles with small rear ends (trailers with no load on board etc.)
Motorcycles traveling in the same lane
Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function effec-
tively:
Keep the sensor and front grille cover clean at all times.
Clean the sensor and front grille cover with a soft cloth so you do not mark or
damage them.
Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may become inaccu-
rate or malfunction. If the sensor or surrounding area is subject to a strong
impact, always have the area inspected and adjusted by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
Do not modify or paint the sensor and grille cover.
