How to use the camera

●

The parking assist monitor may not operate properly in the following cases.
• If the back of the vehicle is hit, the position and mounting angle of the camera may

change.

• As the camera has a water proof construction, do not detach, disassemble or

modify it. This may cause incorrect operation.

• When cleaning the camera lens, flush the camera with a large quantity of water

and wipe it with a soft and wet cloth. Strongly rubbing the camera lens may cause

the camera lens to be scratched and unable to transmit a clear image.

• Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to

the camera. If this happens, wipe it off as soon as possible.

• If the temperature changes rapidly, such as when hot water is poured on the vehi-

cle in cold weather, the system may not operate normally.

• When washing the vehicle, do not apply intensive bursts of water to the camera or

camera area. Doing so may result in the camera malfunctioning.

• When the camera is used under fluorescent lights, sodium light or mercury light

etc., the lights and the illuminated areas may appear to flicker.

●

Do not expose the camera to strong impact as this could cause a malfunction.

If this happens, have the vehicle inspected by your Lexus dealer as soon as possible.

tioning system to enhance fuel efficiency (

P. 420, 427). To improve air conditioning

performance, adjust the fan speed or turn off Eco drive mode.

■

Sport mode automatic deactivation
Sport mode is automatically deactivated if the power switch is turned off after driving in

sport mode.

The driving modes can be selected to suit driving conditions.

238

Driving assist systems

◆

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)

Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads

◆

EPS (Electric Power Steering)

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

◆

Enhanced VSC (Enhanced Vehicle Stability Control)

Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance.

◆

Hill-start assist control

Helps to prevent the vehicle from rolling backward when starting on an incline

◆

PCS (Pre-Collision System) (if equipped)

P. 242

To help enhance driving safety and performance, the following systems oper-
ate automatically in response to various driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too
heavily when operating the vehicle.

239

The slip indicator light will flash while
the VSC/TRAC/ABS systems are
operating.

If the vehicle gets stuck in mud, dirt or snow, the TRAC system may reduce

power from the hybrid system to the wheels. Pressing

to turn the system

off may make it easier for you to rock the vehicle in order to free it.
To turn the TRAC system off, quickly

press and release

The “TRAC OFF” indicator light will

come on.

Press

again to turn the system

back on.

■

When the “TRAC OFF” indicator comes on even if the TRAC OFF switch has not been

pressed
TRAC and hill-start assist control cannot be operated. Contact your Lexus dealer.

■

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

control systems

●

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 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.

When the VSC/TRAC/ABS systems are operating

Disabling the TRAC system

240

■

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 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 nor-

mal within 10 minutes.

■

Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will operate:

●

The shift position is in a position other than P or N (when starting off forward/backward

on an upward incline).

●

The vehicle is stopped.

●

The accelerator pedal is not depressed.

●

The parking brake is not engaged.

■

Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:

●

Shift the shift position to P or N

●

The accelerator pedal is depressed

●

The parking brake is engaged.

●

Approximately 2 seconds elapse after the brake pedal is released.

■

Automatic reactivation of TRAC system
After turning the TRAC system off, the system will be automatically re-enabled in the fol-

lowing situations:

●

When the power switch is turned off

●

The TRAC will turn on when vehicle speed increases

241

WARNING

■

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 vehicle’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

■

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.

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.

■

Hill-start assist control does not operate effectively when

●

Do not overly rely on the hill-start assist control. The 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.

■

When the TRAC 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 TRAC 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 TRAC 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 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.

242

PCS (Pre-Collision System)



◆

Pre-collision seat belts (front seat belts only)

If the pre-collision sensor detects that a collision is unavoidable, the pre-colli-
sion 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. 35)

However, when the VSC system is disabled, 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 possibility of a frontal collision, the system warns the
driver using a warning light, warning display and buzzer. If the system deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed. Pre-collision braking can be disabled using the
pre-collision braking off switch.

Pre-collision braking disabled
Pre-collision braking enabled
The “PCS” warning light will turn on
when pre-collision braking is dis-
abled.



: If equipped

When the radar sensor detects possibility of a frontal collision, the pre-colli-
sion system such as the brakes and seat belts are automatically engaged to
lessen impact as well as vehicle damage.

Disabling pre-collision braking

243

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-collision system is operational when

●

Pre-collision seat belts (type A)
• Vehicle speed is greater than about 19 mph (30 km/h).

• The system detects sudden braking or skidding.

• The front occupants are wearing a seat belt.

●

Pre-collision seat belts (type B)
• Vehicle speed is greater than about 4 mph (5 km/h).

• The speed at which your vehicle is approaching the obstacle or the vehicle running

ahead of you is greater than about 19 mph (30 km/h).

• The front occupants are wearing a seat belt.

●

Pre-collision brake assist:
• Vehicle speed is greater than about 19 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 19 mph (30 km/h).

• The brake pedal is depressed.

●

Pre-collision braking:
• The pre-collision braking off switch is not pressed.

• Vehicle speed is greater than about 10 mph (15 km/h).

• The speed at which your vehicle is approaching the obstacle or the vehicle running

ahead of you is greater than about 10 mph (15 km/h).

244

■

Conditions that may trigger the system even if there is no possibility of a collision
In any of the following situations where the frontal area of the radar sensor is interrupted,

the radar sensor may detect possibility of a frontal collision and the system may be acti-

vated.

●

When passing by an oncoming vehicle in a curve or a turn to the right or the left

●

When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll gate barrier,

etc.)

●

When there is a structural object (billboard, low ceiling, fluorescent light, etc.) above

the uphill road ahead

●

When driving on a narrow road or through under a low overhead structure (bridge,

tunnel, fly-under, etc.)

●

When driving on an uneven road surface

●

When there is a metal object, bump, or protrusion on the road surface

●

When vehicle’s front part is raised or lowered depending on loading conditions

●

When the direction of radar sensor is misaligned by strong impact applied on an area

around the radar sensor, etc.

●

When there is an obstacle (guard rail, etc.) by the roadside at the entrance to a curve

●

When the front of your vehicle is pointing upwards (caused by putting a heavy load in

the luggage compartment etc.)

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 may 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 occa-

sions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees,

or snowdrifts.

■

Situations in which the pre-collision 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

●

Due to greatly turning the steering wheel when an obstacle suddenly appears ahead

245

■

Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors

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

P. 535, 542)

WARNING

■

Limitations of the pre-collision system
The driver is solely responsible for safe driving. Always drive safely, taking care to

observe your surroundings.
Do not use the pre-collisions system instead of normal braking operations under any

circumstances. This system will not prevent collisions or lessen damage or injuries in all

cases. Do not overly rely on this system. Failure to do so may cause an accident, result-

ing in death or serious injury.
This system has been designed to help avoid and reduce the impact of collisions. How-

ever, the system operates differently depending on the situation (

P. 243, 244). As a

result, the same level of performance may not be expected in all cases. Also, the pre-

collision’s brakes may not operate if the driver is depressing the brake pedal or turning

the steering wheel, as the system will determine such conditions as collision avoidance

operations.

246

WARNING

■

Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision system is intended to assist the

driver in avoiding collisions through the process of LOOK-JUDGE-ACT. There are

limits to the degree of assistance the system can provide, so please keep in mind the

following important points.

●

Assisting the driver in watching the road

The pre-collision system is only able to detect obstacles directly in front of the vehicle,

and only within a limited range. It is not a mechanism that allows careless or inatten-

tive driving, and it is not a system that can assist the driver in low-visibility conditions. It

is still necessary for the driver to pay close attention to the vehicle’s surroundings.

●

Assisting the driver in making correct judgement

When attempting to estimate the possibility of a collision, the only data available to

the pre-collision system is that from obstacles it has detected directly in front of the

vehicle. Therefore, it is absolutely necessary for the driver to remain vigilant and to

determine whether or not there is a possibility of collision in any given situation.

●

Assisting the driver in taking action

The pre-collision system’s braking assist feature is designed to help reduce the sever-

ity of a collision, and so only acts when the system has judged that a collision is

unavoidable. This system is not capable of automatically avoiding a collision or bring-

ing the vehicle to a stop safely without appropriate operations performed by the

driver. For this reason, when encountering a dangerous situation the driver must take

direct and immediate action in order to ensure the safety of all involved.

■

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 functioning

of the sensor

●

When your vehicle is pointing upwards (caused by a heavy load in the luggage com-

partment 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-collision system can function effectively:

●

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 dam-

age 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 inaccurate or

malfunction. If the sensor or surrounding area is subject to a strong impact, always

have the area inspected and adjusted by your Lexus dealer.

●

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.

●

If the sensor needs to be replaced, contact your Lexus dealer.

Hybrid vehicle driving tips

◆

Using Eco drive mode

When using Eco drive mode, the torque corresponding to the accelerator
pedal depression amount can be generated more smoothly than it is in normal
conditions. In addition, the operation of the air conditioning system (heating/
cooling) will be minimized, improving the fuel economy. (

P. 237)

◆

Use of Hybrid System Indicator

The Eco-friendly driving is possible by keeping the indicator needle of Hybrid
System Indicator within Eco area. (

P. 88)

◆

Shift lever operation

Shift the shift position to D when stopped at a traffic light, or driving in heavy
traffic etc. Shift the shift position to P when parking. When using the N posi-
tion, there is no positive effect on fuel consumption. In the N position, the gas-
oline engine operates but electricity cannot be generated. Also, when using
the air conditioning system, etc., the hybrid battery (traction battery) power is
consumed.

◆

Accelerator pedal/brake pedal operation

●

Drive your vehicle smoothly. Avoid abrupt acceleration and deceleration.
Gradual acceleration and deceleration will make more effective use of the
electric motor (traction motor) without having to use gasoline engine
power.

●

Avoid repeated acceleration. Repeated acceleration consumes hybrid bat-
tery (traction battery) power, resulting in poor fuel consumption. Battery
power can be restored by driving with the accelerator pedal slightly
released.

◆

When braking

Make sure to operate the brakes gently and in a timely manner. A greater
amount of electrical energy can be retained when slowing down.

For economical and ecological driving, pay attention to the following points:

248

◆

Delays

Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check traffic reports before leaving and avoid
delays as much as possible. When driving in a traffic jam, gently release the
brake pedal to allow the vehicle to move forward slightly while avoiding over-
use of the accelerator pedal. Doing so can help control excessive gasoline
consumption.

◆

Highway driving

Control and maintain the vehicle at a constant speed. Before stopping at a toll
booth or similar, allow plenty of time to release the accelerator and gently
apply the brakes. A greater amount of electrical energy can be regenerated
when slowing down.

◆

Air conditioning

Use the air conditioning only when necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recirculated air
mode. Doing so will help to reduce the burden on the air conditioning system
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out until it
and the interior of the vehicle are warm, it will consume fuel. Fuel consumption
can be improved by avoiding overuse of the heater.

◆

Checking tire inflation pressure

Make sure to check the tire inflation pressure frequently. Improper tire infla-
tion pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on dry roads
can lead to poor fuel economy. Use tires that are appropriate for the season.

◆

Luggage

Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.

◆

Warming up before driving

Since the gasoline engine starts up and cuts out automatically when cold,
warming up the engine is unnecessary. Moreover, frequently driving short dis-
tances will cause the engine to repeatedly warm up, which can lead to excess
fuel consumption.

249

Winter driving tips

●

Use fluids that are appropriate to the prevailing outside temperatures.

• Engine oil
• Engine/power control unit coolant
• Washer fluid

●

Have a service technician inspect the condition of the 12-volt battery.

●

Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the front tires.

Ensure that all tires are the same size and brand, and that chains match the size of the

tires.

Perform the following according to the driving conditions:

●

Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to melt the ice. Wipe away the water imme-
diately to prevent it from freezing.

●

To ensure proper operation of the climate control system fan, remove any
snow that has accumulated on the air inlet vents in front of the windshield.

●

Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes.

●

Remove any snow or mud from the bottom of your shoes before getting in the
vehicle.

Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.
