Turning on the high beam headlights

With the headlights on, push the lever away from you to turn on the high beams. Pull the lever toward you to the center position to turn the high beams off. Pull the lever toward you and release it to flash the high beams once. You can flash the high beams with the headlights on or off.

■Daytime running light system

●For the U.S.A.: To make your vehicle more visible to other drivers, the daytime running lights turn on automatically whenever the hybrid system is started and the parking brake is released. Daytime running lights can be turned off by operating the switch. (if equipped) For Canada: To make your vehicle more visible to other drivers, the day- time running lights turn on automatically (at a reduced intensity) whenever the hybrid system is started and the parking brake is released. Daytime running lights are not designed for use at night.

●For Canada: Compared to turning on the headlights, the daytime running light system offers greater durability and consumes less electricity, so it can help improve fuel economy.

Driving in vehicle-to-vehicle distance control mode

This mode employs a radar sensor to detect the presence of vehicles up to approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle following distance, and operates to maintain a suit- able following distance from the vehicle ahead.

Note that vehicle-to-vehicle distance will close in when traveling on long downhill slopes.

277

PRIUS_OM_OM47791U_(U)

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. ■ Warnings may not occur when

In the following instances, there is a possibility that the warnings will not occur: ● When the speed of the vehicle ahead matches or exceeds your

vehicle speed

● When the vehicle ahead is traveling at an extremely slow speed ● Immediately after the cruise control speed was set ● At the instant the accelerator is applied

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.

2-4. Using other driving systems

CAUTION

■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. 279) 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

■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

CAUTION

■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 grille cover clean at all times.

Clean the sensor and 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 inaccurate or malfunction. If the sensor or surrounding area is subject to a strong impact, always have the area inspected and adjusted by your 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.

If the steering wheel is not operated for approximately 15 seconds on a straight road or approximately 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 driving.

■After the vehicle has been parked in the sun

The LKA system functions may not be available and a warning message (→P. 520) will be displayed for a while after driving has started. In such cases, turn the LKA system off and turn it on again after normal temperature returns. When the temperature in the cabin decreases and the temperature around the camera sensor (→P. 289) becomes suitable for its operation, the functions will begin to operate.

■If there are lane markers on only one side of the vehicle

The lane keeping assist function will not operate. Also, the lane departure warning will not operate for the side on which lane markers could not be rec- ognized.

■Conditions in which the function may not operate correctly

In the following conditions, the LKA system functions may not operate, or it may not be possible to ensure adequate performance. Also, the camera sensor may be unable to recognize lane lines causing the lane departure warning function to operate incorrectly, or the lane keeping assist function may not operate properly. However, this does not indicate a malfunction. ●When driving through an area with no lane markers, such as a tollbooth,

a crossing or before a ticket checkpoint

●When driving on a sharp curve ●When lanes are extremely narrow or extremely wide ●When the vehicle leans to one side an unusual amount due to a heavy

load or improper tire inflation pressure

●When the following distance between your vehicle and the vehicle ahead

is extremely short

●When the lane markers are yellow (These may be more difficult for the

system to recognize compared to white markers.)

●When the lane markers are broken, “Botts’ dots”, “Raised pavement

marker” or stones

●When lane markers are obscured or partially obscured by sand, dirt, etc. ●When there are shadows on the road running parallel with lane markers,

or if a shadow covers the lane markers

●When driving on a particularly bright road surface, such as concrete ●When driving on a road surface that is bright due to reflected light ●When driving in a location where the light level changes rapidly, such as

the entrance to or exit from a tunnel

●When sunlight or the headlights of oncoming vehicles are shining directly

into the camera lens

●When driving on roads that are branching or merging ●When driving on a road surface that is wet due to rain, previous rainfall,

standing water, etc.

●When the vehicle experiences strong up-and-down motion such as when

driving on an extremely rough road or on a seam in the pavement

●When headlight brightness at nighttime is reduced due to dirt on the

lenses, or when the headlights are misaligned

●When driving with a strong crosswind ●When driving on winding roads or roads that are uneven ●When driving on rough or unpaved roads

■When changing the tires

Depending on the tires used, sufficient performance may not be maintain- able.

■Warning messages for LKA

Warning messages are used to indicate a system malfunction or to inform the driver of the need for caution while driving. (→P. 516, 520)

CAUTION

■Before using the LKA system

Do not rely solely on the LKA system. The LKA system does not drive the vehicle automatically, nor does it reduce the amount of care you need to take. As such, the driver must always assume full responsibility for under- standing his/her surroundings, for operating the steering wheel to correct the driving line, and for driving safely. Inappropriate or negligent driving could lead to an accident.

■To avoid operating the LKA by mistake

Switch the LKA off using the “LKA” switch when not in use.

■Situations unsuitable for LKA

Do not use LKA in any of the following situations. Otherwise, the system may not function correctly and could result in an acci- dent. ●When driving with snow tires, tire chains, a spare tire, or similar equipment ●When the tires have been excessively worn, or when the tire inflation pres-

sure is low.

●When there are objects or structures along the roadside that might be mis- interpreted as lane markers (such as guardrails, curb, reflector posts, etc.)

●When driving on snowy roads ●When pavement lane markers are difficult to see due to rain, snow, fog,

etc.

●When there are visible lines on the pavement from road repairs, or if the

remains of old lane markers are still visible on the road

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

snow

●When driving in a lane other than the driving or passing lanes on a freeway

or highway

●When driving on a road with lane closures due to maintenance, or when

driving in a temporary lane ●During emergency towing

NOTICE

■To prevent damage to or incorrect operation of the LKA system

●Do not modify the headlights or attach stickers to the surface of the lights. ●Do not modify the suspension or sun visor, or replace them with non-genu-

ine parts.

●Do not install or place anything on the hood or the grille. Also, do not install

a grille guard (bull bars, kangaroo bar etc.).

●Do not modify the sun visor or replace it with anything other than a genu-

ine Toyota product.

●If your windshield needs repairs, contact your Toyota dealer.

■Camera sensor (→P. 289)

Observe the following to ensure that the LKA system functions correctly. ●Keep the windshield clean at all times.

Performance could be affected if the windshield is dirty, or if raindrops, condensation or ice are adhering to the windshield.

●Do not attach a sticker or other items to the windshield near the camera sensor. ●Do not install or place anything near the

camera.

●When adjusting the rear view mirror, make sure that it does not block the

camera lens.

●Do not attach window tinting to the windshield. ●Do not install an antenna in front of the camera lens. ●If the windshield is fogged up, use the windshield defogger to remove fog

from the windshield. 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.

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

■ 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 spin- ning 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 surfaces by controlling steering performance.

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

TRAC ●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 sys- tem 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 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 normal within 10 minutes. *: If the LKA (Lane-Keeping Assist) system (if equipped) cannot operate in this case, a warning message will be shown on the multi-information dis- play.

CAUTION

■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 nor-

mal 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 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

■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 system is operating. Do not drive the vehicle 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.

CAUTION

■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 and VSC systems will not function correctly if different tires are installed on the vehicle. Contact your Toyota 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.

A buzzer will sound once to indicate the system is acti- vated. 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

illuminated.

■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 if the operat- ing 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.

• 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.

■If the slip indicator light comes on

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

CAUTION

■Hill-start assist control

●Do not overly rely on the 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 PCS (Pre-Collision System)∗

When the radar sensor detects possibility of a frontal collision, the pre-collision systems such as the brakes and seat belts are automat- ically engaged to lessen impact as well as vehicle damage. ■ Pre-collision seat belts (front seat belts only)

If the pre-collision sensor detects that a collision is unavoidable, the pre-collision 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. 113) However, when the VSC system is disabled, the system will not oper- ate 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 sys- tem determines that a collision is unavoidable, the brakes are automat- ically applied to reduce the collision speed. Pre-collision braking can be disabled using the pre-collision braking off switch.
