approximately 400 ft. (120 m) ahead and to judge the distance between
your vehicle and those the vehicle ahead of you.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.

1. Example of constant speed cruising.

1. Example of constant speed cruising.
When there are no vehicles ahead.
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle
distance can also be set by operating the vehicle-to-vehicle distance control.
2. Example of deceleration cruising.
When the vehicle ahead is driving slower than the set speed.
When a vehicle is detected running ahead of you the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is necessary,
the system applies the brakes. A warning tone warns you when the
system cannot decelerate sufficiently to prevent your vehicle from closing in
on the vehicle ahead.
3. Example of follow-up cruising.
When following a vehicle driving slower than the set speed.
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance
set by the driver.
4. Example of acceleration.
When there are no longer any vehicles driving slower than the set
speed.
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

Approach warning

When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the cruise control is not possible, the display will
flash and the buzzer will sound to alert the driver. An example of this
would be if another driver cuts in front of you while you are following a
vehicle. Apply the brakes to ensure an appropriate vehicle-to-vehicle distance.

CAUTION:
Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
Assisting the driver to measure following distance
The dynamic radar cruise control is only intended to help the driver in determining
the following distance between the driver’s own vehicle 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 necessary for driver to pay close attention to the vehicle’s surroundings.
Assisting the driver to judge proper following distance
The dynamic radar cruise control determines whether the following distance
between the driver’s own vehicle and a designated vehicle traveling ahead is
appropriate or not. It is not capable of making any other type of judgement.
Therefore, it is absolutely necessary for the driver to remain vigilant 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 has no 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 vehicle and act appropriately in
order to ensure the safety of all involved.
To avoid inadvertent cruise control activation
Switch the cruise control off using the “ON-OFF” button when not in use.

CAUTION:
Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an accident
resulting in death or serious injury.
In heavy traffic.
On roads with sharp bends.
On winding roads.
On slippery roads, such as those covered with rain, ice and 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 expressways.
When weather conditions are bad enough that they may prevent the sensors
from functioning correctly (fog, snow, sandstorm, heavy rain, etc.).
When an approach warning buzzer is heard often.
When your vehicle is towing a trailer (AWD models with towing package) or during
emergency towing.
When the sensor may not be correctly detecting the vehicle ahead.
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning will not be activated, and a fatal or serious accident
may result.
Vehicles that cut in suddenly.
Vehicles traveling at low speeds.
Vehicles that are not moving.
Vehicles with small rear ends (trailers with no load on board etc.).
Motorcycles traveling in the same lane.

CAUTION:
Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the following conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a fatal or serious accident may
result:
When water or snow thrown up by the surrounding vehicles hinders the functioning
of the sensor.
When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.).
When the road curves or when the lanes are narrow.
When steering wheel operation or your position in the lane is unstable.
When the vehicle ahead of you decelerates suddenly.
Handling the radar sensor.
Observe the following to ensure the cruise control system can function effectively.
Otherwise, the system may not function correctly and could result in an accident.
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

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 braking 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

TRAC (Traction Control)

Maintains drive power and helps to prevent any of the drive wheels from
spinning when the vehicle is started or accelerated on a slippery road surface

EPS (Electric Power Steering)

Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

Active stabilizer suspension system (if equipped)

Reduces sway when cornering according to vehicle conditions such as
steering wheel movement and vehicle speed, in order to maintain a stable
vehicle posture

VDIM (Vehicle Dynamics Integrated Management)

Provides integrated control of the ABS, brake assist, TRAC, VSC, hill-start
assist control, and EPS systems.
Maintains vehicle stability when swerving on slippery road surfaces by
controlling the brakes and hybrid system output.

When the VSC/TRAC systems are operating

If the vehicle is in danger of slipping

If the vehicle is in danger of slipping
or if any of the drive wheels
spins, the slip indicator light flashes
to indicate that the VSC/TRAC
systems are operating.
A buzzer (intermittent) sounds to
indicate that VSC is operating.

Disabling TRAC and/or VSC systems

If the vehicle gets stuck in fresh snow or mud, the TRAC/VSC systems
may reduce power from the hybrid system to the wheels. You may need
to turn the system off to enable you to rock the vehicle in order to free it.

Turning off the TRAC system only

To turn the TRAC system off,

To turn the TRAC system off,
quickly press and release the button.
A message will be shown on the
multi-information display.
Press the button again to turn the
system back on.

Turning off both TRAC and VSC systems

To turn the TRAC and VSC systems

To turn the TRAC and VSC systems
off, press and hold the button
for more than 3 seconds while the
vehicle is stopped.
A message will be shown on the
multi-information display and VSC
off indicator light will come on.

systems back on.

Sounds and vibrations caused by the ABS, VSC, TRAC and brake assist

A sound may be heard from the engine compartment when the hybrid system 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 operating.
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.

Reactivation of the TRAC /VSC systems

Turning off the hybrid system after turning off the TRAC/VSC systems will automatically
reactivate them.

Reactivation of the TRAC system linked to vehicle speed

When only the TRAC system is turned off, the TRAC system will turn on when vehicle
speed increases. However, when both TRAC and VSC systems are turned off,
the systems will not turn on even when vehicle speed increases.

Reduced effectiveness of the EPS system

The effectiveness of the EPS system is reduced to prevent the system from overheating
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.

If the slip indicator comes on

It may indicate a malfunction in the VSC or TRC function.
Contact your Lexus dealer.

CAUTION:
The ABS does not operate effectively when
Tires with inadequate gripping ability are used (such as excessively worn tires on
a snow covered road).
The vehicle hydroplanes while driving at high speed on a wet or slick road.
Stopping distance when the ABS is operating will exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain
a safe distance from the vehicle in front of you 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 roads with uneven surfaces.
TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road
surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.

CAUTION:
When the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indicator
light flashes and a buzzer sounds.
When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to ensure vehicle stability and driving force, do not turn the
TRAC/VSC systems off unless necessary.
Replacing tires
Make sure that all tires are of the same size, 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 and VSC systems will not function correctly if different tires are installed
on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect the driving
assist systems, and may cause a system malfunction.

Hill-start assist control

Hill-start assist control helps to prevent the vehicle from rolling backwards
when starting on an incline or slippery slope.

To engage hill-start assist control,

To engage hill-start assist control,
further 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 can be operated when

l The shift lever is in a position other than P.
The parking brake is not applied.
The accelerator pedal is not depressed.

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.

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 within approximately 2 seconds of
releasing the brake pedal.
• The shift lever is moved to P.
• The parking brake is applied.
• The brake pedal is depressed again.
• The brake pedal has been depressed for more than approximately 3 minutes.

If the slip indicator comes on

It may indicate a malfunction in the system. Contact your Lexus dealer.

CAUTION:
Hill-start assist control
Do not overly rely on hill-start assist control. Hill-start assist control may not operate
effectively on extremely steep inclines or roads covered in 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 control to hold the vehicle on an incline for an extended period of time, as
doing so may lead to an accident.

Pre-Collision System

When the radar sensor detects an unavoidable frontal collision, safety systems
such as the brakes and seat belts are automatically engaged in an
attempt to lessen vehicle damage.

Pre-collision seat belts (front seat belts only)

If the pre-collision sensor detects that a collision is unavoidable, the precollision
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.
However, the system will not operate in the event of skidding when the
TRAC/VSC systems are disabled.

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.

Radar sensor

The radar sensor detects vehicles

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.

The pre-collision system is operational when

Pre-collision seat belts linked to the radar sensor
• Vehicle speed is greater than about 3 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or oncoming
vehicle is greater than about 18 mph (30 km/h).
• The front occupants are wearing a seat belt.
Pre-collision seat belts in the event of sudden braking or skidding
• Vehicle speed is greater than about 18 mph (30 km/h).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
Pre-collision brake assist
• Vehicle speed is greater than about 18 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle
running ahead of you is greater than about 18 mph (30 km/h).
• The brake pedal is depressed.

Conditions that may trigger the system even if there is no danger of 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.
When passing an oncoming vehicle on a left-turn.
When your vehicle rapidly closes on the vehicle in front.
When the system is activated in the situations described above, there is also a possibility
that the seat belts will retract 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 such as traffic cones. There may also be
occasions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles,
trees, or snowdrifts.

When there is a malfunction in the system

Warning lights and/or warning messages will turn on or flash.
