■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as excessively
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 conditions
The ABS is not designed to shorten the vehi cle’s stopping distance. Always maintain a
safe distance from the vehicle in front of you, especially in the following 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 dr ive 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 this is
the system to help ensure vehicle stability and driving force, do not turn the TRC sys-
tem 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 recom-
mended 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 modi fying 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, fur-
ther depress the brake pedal when the
vehicle is stopped completely.
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 wh ile the slip indicator light is illuminated.
■Hill-start assist control
●While hill-start assist control is operating, the brakes rema in 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 depr ess it again. If the system still does not
operate, check if the operating conditions explained above have been met.
■Hill-start assist control buzzer
●When hill-start assist control is activated, the buzzer will sound once.
●In the following situations, hill-start assist control will be canceled and the buzzer will
sound twice.
• No attempt is made to drive the vehicle wi thin approximately 2 seconds of releasing
the brake pedal.
• Push the P position switch.
• The parking brake is applied.
• The brake pedal is depressed again.
• The brake pedal has been depressed for more than approximately 3 minutes.
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 slip-
pery slope.

■Hill-start assist control
●Do not overly rely on hill-start assist control. Hill-start assist control may not operate
effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist control is not intended to hold the vehicle
stationary for an extended period of time. Do not attempt to use hill-start assist con-
trol to hold the vehicle on an incline, as doing so may lead to an accident.

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 con-
trol of the vehicle. ( →P. 3 9 )
However, when the VSC system is disabled, the system will not operate 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 di splay and buzzer. If the system deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed. Pre-crash braking can be disabled using the pre-
crash braking off switch.
Pre-crash braking disabled
Pre-crash braking enabled
The “PCS” warning light will turn on
when pre-crash braking is disabled.
∗: If equipped
When the radar sensor detects possibilit y 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.

The radar sensor detects vehicles or
other obstacles on or near the road
ahead and determines whether a colli-
sion is imminent based on the position,
speed, and heading of the obstacles.
■The pre-crash safety system is operational when
●Pre-crash seat belts (type A)
• Vehicle speed is greater than about 30 km/h (19 mph).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
●Pre-crash seat belts (type B)
• Vehicle speed is greater than about 5 km/h (4 mph).
• The speed at which your vehicle is approaching the obstacle or the vehicle runningahead of you is greater than about 30 km/h (19 mph).
• The front occupants are wearing a seat belt.
●Pre-crash brake assist:
• Vehicle speed is greater than about 30 km/h (19 mph).
• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greater than about 30 km/h (19 mph).
• The brake pedal is depressed.
●Pre-crash braking:
• The pre-crash braking off switch is not pressed.
• Vehicle speed is greater than about 15 km/h (10 mph).
• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greater than about 15 km/h (10 mph).

■Conditions that may trigger the system even if there is no possibility of a collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface (nose up, nose down)
●When passing an oncoming vehicle on a left-turn (left-hand drive vehicles) or right-turn
(right-hand drive vehicles)
●When your vehicle rapidly closes on the vehicle in front
●When a grade separation/interchange, sign, billboard, or other structure appears to be
directly in the vehicle’s line of travel
●When the steep angle of the road causes a metal object located beneath the road sur-
face to be seen ahead of the vehicle
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
●When passing through certain toll gates
●When passing through an overpass
●When passing through a tunnel
When the system is activated in the situations described above, there is also a possibility
that the seat belts will retrac t quickly and the brakes will be applied with a force greater
than normal. When the seat belt is locked in the retracted position, stop the vehicle in a
safe place, release the seat belt and refasten it.
■Obstacles not detected
The sensor cannot detect plastic obstacles su ch as traffic cones. There may also be occa-
sions when the sensor cannot detect pedestri ans, animals, bicycles, motorcycles, trees,
or snowdrifts.
■Situations in which the pre-crash safe ty system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●When your vehicle is skidding with the VSC system off
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
■Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors
being unable to detect obstacles, the pre-crash safety system will be automatically dis-
abled. In this case, the system will not activa te even if there is a collision possibility.
■When there is a malfunction in the system, or if the system is temporarily unusable
Warning lights and/or warning messages will turn on or flash. (→P. 5 1 5 , 5 2 1 )
