Driving in vehicle-to-vehicle distance control mode

This mode employs a sensor to detect the presence of vehicles up to 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.

222

2-4. Using other driving systems

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 dis- tance control. 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 automati- cally 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. 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 dis- tance set by the driver. Example of acceleration When there are no longer any vehicles ahead 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 dis- play will flash and the buzzer will sound to alert the driver. An exam- ple 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 vehi- cle-to-vehicle distance.

CAUTION

■Before using dynamic radar cruise control

Do not overly rely on vehicle-to-vehicle distance control. Be aware of the set speed. If automatic deceleration/acceleration is not appropriate, adjust the vehicle speed, as well as the distance between your vehicle and vehicles ahead by applying the brakes etc.

■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 care- less 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 dis- tance 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 dan- ger, 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 acci- dent 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 sen-

sors from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)

●When an approach warning buzzer can be heard often

■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 (→P. 227) 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

229

2-4. Using other driving systems

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 sen- sor 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 lug-

gage 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 effec- tively. Otherwise, the system may not function correctly and could result in an acci- dent. ●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 malfunction. If the sensor or surrounding area is subject to a strong impact, always have the area inspected and adjusted by a Toyota dealer.

●Do not disassemble the sensor. ●Do not attach accessories or stickers to the sensor, grille cover or sur-

rounding area.

●Do not modify or paint the sensor and grille cover. ●Do not replace them with non-genuine parts.

CAUTION

■When using the rear view monitor system

Observe the following precautions to avoid an accident that could result in death or serious injuries. ●Never depend solely on the monitor system when reversing. ●Always check visually and with the mirrors to confirm your intended path is

clear.

●Depicted distances between objects and flat surfaces differ from actual

distances.

●Do not use the system if the back door is not completely closed.

■Conditions which may affect the rear view monitor system

●If the back of the vehicle is hit, the camera’s position and mounting angle

may change. Contact your Toyota dealer.

●Rapid temperature changes, such as when hot water is poured on the

vehicle in cold weather, may cause the system to function abnormally.

●If the camera lens is dirty, it cannot transmit a clear image. Rinse with water and wipe with a soft cloth. If extremely dirty, wash with a mild cleanser and rinse.

●The displayed image may be darker and moving images may be slightly

distorted when the system is cold.

2-4. Using other driving systems LKA (Lane-Keeping Assist)∗

While driving on a freeway or motor highway that has lane markings, this system recognizes the lanes using a camera as a sensor to assist the driver with staying in the lane. The LKA system has two functions. ■ Lane departure warning function

If the system judges that the vehicle may deviate from its lane, it alerts the driver using rapid beeping, indications on the multi- information display, and a sensory warning* given via the steer- ing wheel. *: A slight steering torque is applied for a short period of time in

the direction of the center of the lane.

■ Lane keeping assist function

This function will be active when the vehicle-to-vehicle distance control mode of the cruise control (→P. 218) is set with vehicle speed above approx. 50 mph (approx. 75 km/h) and while the lane departure warning function is active. When the lane keep- ing assist function is active, a slight steering torque will be applied, to help the driver maintain the vehicle inside the lane.

∗: If equipped 235

2-4. Using other driving systems

■ Turning the LKA system on

The lane departure warning function and lane keeping assist function will be automatically activated depending on the recog- nition condition of lane markings, vehicle speed and the setting of radar cruise control (vehicle-to-vehicle distance control mode).

Press the “LKA” switch to acti- vate the system.

Press the switch again to turn the LKA system off.

■Temporary cancellation of the LKA system functions

If any of the following occurs, the LKA system functions will be temporarily canceled. The functions will resume after the necessary operating conditions have returned. ●The turn signal lever is operated. ●The steering wheel is turned as far as necessary to cause the vehicle to

change lanes.

●The brake pedal is depressed.

The lane keeping assist function will not resume even after the brake pedal is released because depressing the brake pedal also cancels the dynamic radar cruise control.

●The vehicle speed deviates from the operating range of the LKA system functions. (The buzzer will beep twice when the lane keeping assist func- tion is being canceled.)

●When the lane lines cannot be recognized while driving. (The buzzer will

beep twice when the lane keeping assist function is being canceled.)

●Low speed or high speed wiper operation states. (The buzzer will beep

twice when the lane keeping assist function is being canceled.) The buzzer may not beep when the LKA system functions are canceled because the notification of dynamic radar cruise control cancellation takes priority over the LKA system and cancels the function.

●The no-handed driving warning activates while the lane keeping assist

function is active. (The buzzer will beep twice.)

239

2-4. Using other driving systems

■No-handed driving warning

If the steering wheel is not operated for about 15 seconds on a straight road or about 5 seconds on a curve, the buzzer will beep twice, indicators on the multi-information display will flash, and the lane keeping assist function will be temporarily canceled. If you drive the vehicle with your hands lightly touching the steering wheel, this may also be detected as no-handed driv- ing.

■When the vehicle has been parked in the sun

The LKA system functions may not be available for a while after driving has started. In such cases, turn the LKA system off and turn it on again after nor- mal temperature returns. When the temperature in the cabin decreases and the temperature around the camera sensor becomes suitable for its opera- tion, the functions will begin to operate.

CAUTION

■Before using the LKA system

Do not rely on the LKA system to remain within a selected lane. The LKA system is not designed to enable inattentive driving. The steering wheel should be operated by the driver to maintain the vehicle in a suitable position within its lane. Always drive carefully.

CAUTION

■Situations unsuitable for the LKA system

Using the LKA system in any of the following situations may result in improper operation of the system and could lead to an accident, causing death or serious injury. Turn the LKA system off while driving in any of the following situations. ●When it is difficult to see lane markings because they are dirty or not clear ●When it is difficult to see lane markings due to rain, snow, fog or glare ●When the headlights are not bright enough due to dirt on the lenses or if

the headlight aim is not adjusted appropriately

●When a lane marking is not present, such as before tollbooths on a free-

way

●When sudden changes in the light level occur repetitively ●When there are misleading lines such as shadows, lines of snow, wheel

ruts with rain collected in them, or lines that remain after road repairs

●When driving in lanes other than the driving lane or passing lane on free-

way or motor highways

●When there is a lane closure due to road repairs or when driving in a

makeshift lane

●When the lanes are narrow or wide ●When the distance from the vehicle ahead of you is short ●When the vehicle leans to one side an unusual amount due to a heavy

load or improper tire inflation pressure

●When driving on winding roads or on uneven roads ●When driving on slippery roads, such as those covered with rain, ice or

snow

●The tires have been exchanged (including snow tires), or the suspension

has been modified

NOTICE

■Camera sensor

Observe the following to ensure that the LKA system functions correctly.

ITO24P134

●Keep the windshield clean at all times.

LKA performance may deteriorate due to the presence of raindrops, con- densation, ice or snow on the windshield.

●Do not subject the camera sensor to strong impact or force, and do not

disassemble the camera sensor.

●Do not change the installation position of the camera sensor or remove it.

The direction of the camera sensor is precisely adjusted.

●When it is cold, using the heater with air blowing to the feet may allow the upper part of the windshield to fog up. This will have a negative effect on the images. In such a case, use the windshield defogger to provide warm, dry air to the windshield.

●Do not place anything on the dashboard.

The camera sensor may recognize the image reflected on the windshield as lane markings by mistake.

●Do not scratch the camera lens, or let it get dirty. ●Do not attach a sticker or other items to the windshield near the camera

sensor.

■Hill-start assist control operating conditions The system operates in the following situations: • The shift position is in 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 automati- cally 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 that the oper- ating 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 “P” position switch is pressed. • The parking brake is applied. • The brake pedal is depressed again.

■If the slip indicator comes on...

It may indicate a malfunction in the system. Contact your Toyota 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.

2-4. Using other driving systems Driving assist systems

To help enhance driving safety and performance, the following sys- tems operate 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. ■ 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.

■ Enhanced 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 prevents the front wheels from spinning when starting the vehicle or accelerating on slippery roads.

■ Hill-start assist control

→P. 243

■ EPS (Electric Power Steering)

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

■ Pre-Collision System (if equipped)

→P. 249

245

2-4. Using other driving systems

When the Enhanced VSC/TRAC is operating

If the vehicle is in danger of slip- ping or if the front wheels spin, the slip indicator light flashes to indicate that the Enhanced VSC/ TRAC have been engaged.

A buzzer (intermittent) sounds to indicate that Enhanced VSC is operating.

ITO24P109

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

Enhanced VSC ●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.

■EPS operation sound

When the steering wheel operates, a motor sound (whirring sound) may be heard. This does not indicate a malfunction.

246

2

2-4. Using other driving systems

■Reduced effectiveness of EPS

The effectiveness of EPS 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 system should return to normal within 10 minutes.

CAUTION

■The ABS does not operate effectively when

●The limits of tire gripping performance have been exceeded. ●The vehicle hydroplanes while driving at high speed on the wet or slick

road.

■Stopping distance when the ABS is operating on the wet or slick roads 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 situ- ations. ●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 pavement

■TRAC may not operate effectively when

Directional control and power may not be achievable while driving on slip- pery road surfaces, even if the TRAC is operating. Do not drive the vehicle in conditions where stability and power may be lost.

247

2-4. Using other driving systems

CAUTION

■When the Enhanced 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.

■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 speci- fied tire pressure level. The ABS and Enhanced VSC will not function correctly if different tires are fitted on the vehicle. Contact your Toyota 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 the system to malfunction.
