When any part of the vehicle sags due to the number of pas- sengers or the distribution of the load, there is a margin of error between the guide lines on the screen and the actual distance/ course on the road. The distance that appears on the screen between three-dimen- sional objects (such as vehicles) and flat surfaces (such as the road) and the actual distance dif- fer as follows. In reality, C = A < B (C and A are equally far away; B is farther than C and A). However, on the screen, the situation appears to be A < B < C. On the screen, it appears that a truck is parking about 3.0 ft. (1.0 m) away. However, in reality if you back up to point A, you will hit the truck. 237 PRIUS_U (OM47685U) DVD 2-4.

Using other driving systems n Rear view monitor system camera In the following cases, it may be difficult to see the images on the screen, even when the system is functioning correctly. l The vehicle is in a dark area, such as at night. l The temperature near the lens is extremely high or low. l Water droplets are on the camera lens or humidity is high, such as when it rains. l Foreign matter, such as snow or mud, adheres to the camera lens. l The sun or headlights are shining directly into the camera lens. l A bright object such as a white wall is reflected in the mirror surface over the monitor. l When the camera has scratches or dirt on it. If a bright light, such as sunlight reflected off the vehicle body, is picked up by the camera, a smear effect* characteristic to the camera may occur. *:Smear effect—A phenomenon that occurs when a bright light (for example, sunlight reflected off the vehicle body) is picked up by the camera; when trans- mitted by the camera, the light source appears to have a vertical streak above and below it. n Smear effect 240 PRIUS_U (OM47685U) DVD 2-4. Using other driving systems n Flicker effect When the camera is used under fluorescent lights, sodium lights, mercury lights, etc., the lights and the illuminated areas may appear to flicker. CAUTION n When using the rear view monitor system Observe the following precautions to avoid an accident that could result in death or serious injuries. l Never depend solely on the rear view monitor system when reversing. l Always check visually and with the mirrors to confirm your intended path is clear. l Always check the vehicle surrounding area, because the guide lines are estimates of distance and location. l The guide lines are assistant lines and do not change even if the steering wheel is turned. l Depicted distances between objects and flat surfaces differ from actual distances. l Do not use the system if the back door is not completely closed. n 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. l 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. l The displayed image may be darker and moving images may be slightly distorted when the system is cold. n Caution while driving in reverse Do not change modes while the vehicle is moving. Doing so may cause an accident. 241 PRIUS_U (OM47685U) DVD 2-4. Using other driving systems NOTICE n Camera precautions l As the camera has a water proof construction, do not detach, disassemble or modify it. This may cause incorrect operation. If the camera lens becomes dirty, it cannot transmit a clear image. If water droplets, snow, or mud adhere to the lens, rinse with water and wipe with a soft cloth. If the lens is extremely dirty, wash it with a mild cleanser and rinse. l 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. l When washing the vehicle, do not apply intensive bursts of water to the camera or camera area. Doing so may result in the camera malfunction- ing. 242 PRIUS_U (OM47685U) DVD 2 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. n 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. n Lane keeping assist function This function will be active when the vehicle-to-vehicle distance control mode of the cruise control (→P. 221) 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 243 PRIUS_U (OM47685U) DVD 2-4. Using other driving systems n 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. ITO24P132 244 PRIUS_U (OM47685U) DVD 2-4.

Using other driving systems n 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. l The turn signal lever is operated. l The steering wheel is turned as far as necessary to cause the vehicle to change lanes. l 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. l 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.) l When the lane lines cannot be recognized while driving. (The buzzer will beep twice when the lane keeping assist function is being canceled.) l 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. l The no-handed driving warning activates while the lane keeping assist function is active. (The buzzer will beep twice.) l When the lane departure warning function is activated. Once the lane departure warning function is activated, it will be tempo- rarily canceled and resume a few seconds later. 247 PRIUS_U (OM47685U) DVD 2-4. Using other driving systems n 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. n 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 n 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. 248 PRIUS_U (OM47685U) DVD 2 2-4. Using other driving systems CAUTION n 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. l When it is difficult to see lane markings because they are dirty or not clear l When it is difficult to see lane markings due to rain, snow, fog or glare l When the headlights are not bright enough due to dirt on the lenses or if the headlight aim is not adjusted appropriately l When a lane marking is not present, such as before tollbooths on a free- way l When sudden changes in the light level occur repetitively l 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 l When driving in lanes other than the driving lane or passing lane on free- way or motor highways l When there is a lane closure due to road repairs or when driving in a makeshift lane l When the lanes are narrow or wide l When the distance from the vehicle ahead of you is short l When the vehicle leans to one side an unusual amount due to a heavy load or improper tire inflation pressure l When driving on winding roads or on uneven roads l When driving on slippery roads, such as those covered with rain, ice or snow l The tires have been exchanged (including snow tires), or the suspension has been modified 249 PRIUS_U (OM47685U) DVD 2-4. Using other driving systems NOTICE n Camera sensor Observe the following to ensure that the LKA system functions correctly. ITO24P134 l 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. l Do not subject the camera sensor to strong impact or force, and do not disassemble the camera sensor. l Do not change the installation position of the camera sensor or remove it. The direction of the camera sensor is precisely adjusted. l 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. l Do not place anything on the dashboard. The camera sensor may recognize the image reflected on the windshield as lane markings by mistake. l Do not scratch the camera lens, or let it get dirty. l Do not attach a sticker or other items to the windshield near the camera sensor. 250 PRIUS_U (OM47685U) DVD 2-4. Using other driving systems Hill-start assist control Hill-start assist control helps to prevent the vehicle from rolling backwards when starting on incline or slippery slope. To engage hill-start assist con- trol, further depress the brake pedal when is stopped completely. the vehicle A buzzer will sound once to indicate the system is acti- vated. The slip indicator will also start flashing. ITO24P109 n 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. n Hill-start assist control l 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. l 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. 251 PRIUS_U (OM47685U) DVD 2-4. Using other driving systems n Hill-start assist control buzzer l 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. n If the slip indicator comes on... It may indicate a malfunction in the system. Contact your Toyota dealer. CAUTION n Hill-start assist control l 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. l 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. 252 PRIUS_U (OM47685U) DVD 2 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. n 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. n Brake assist Generates an increased level of braking force after the brake pedal is depressed, when the system detects a panic stop situation. n VSC (Vehicle Stability Control) Helps the driver to control skidding when swerving suddenly or turning on slippery road surfaces. n 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. n Hill-start assist control →P. 251 n EPS (Electric Power Steering) Employs an electric motor to reduce the amount of effort needed to turn the steering wheel. n Pre-Collision System (if equipped) →P. 257 n 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 surface by controlling steering performance. 253 PRIUS_U (OM47685U) DVD 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 n Sounds and vibrations caused by the ABS, brake assist, TRAC and Enhanced VSC l 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. l 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. n EPS operation sound When the steering wheel operates, a motor sound (whirring sound) may be heard. This does not indicate a malfunction. 254 PRIUS_U (OM47685U) DVD 2 2-4. Using other driving systems n 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 n The ABS does not operate effectively when l The limits of tire gripping performance have been exceeded. l The vehicle hydroplanes while driving at high speed on the wet or slick road. n 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. l When driving on dirt, gravel or snow-covered roads l When driving with tire chains l When driving over bumps in the road l When driving over roads with potholes or roads with uneven pavement n 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. 255 PRIUS_U (OM47685U) DVD 2-4. Using other driving systems CAUTION n 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. n 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. n 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. 256 PRIUS_U (OM47685U) DVD 2 2-4. Using other driving systems Pre-Collision System∗ When the radar sensor detects possibility of a frontal collision, the pre-collision system such as the brakes and seat belts are auto- matically engaged to lessen impact and injuries to occupants as well as vehicle damage. n Pre-collision seat belts If the pre-collision sensor detects that a collision is unavoidable, the pre-collision system will retract the seat belt before the colli- sion occurs. The same will happen if the driver makes an emergency braking or loses control of the vehicle. (→P. 86) However, when the VSC is disabled, the system will not operate in the event of skidding. n 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. n 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 determines that a collision is unavoidable, the brakes are automatically applied to reduce the collision speed. Pre-collision braking can be disabled using the pre-colli- sion braking off switch. ∗: If equipped 257 PRIUS_U (OM47685U) DVD 2-4. Using other driving systems Disabling pre-collision braking Radar sensor Enabled Disabled The “PCS” warning light comes on when the pre-collision braking is disabled. Detects vehicles or other obsta- cles on or near the road ahead and determines whether a colli- sion is imminent based on the position, speed, and heading of the obstacles. ITO24P116 ITO24P131 258 PRIUS_U (OM47685U) DVD 2 2-4. Using other driving systems n Obstacles not detected The sensor cannot detect plastic obstacles such as pylons. There may also be occasions when the radar sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees, or snowdrifts. n The pre-collision system is operational when l Pre-collision seat belts (linked to the radar sensor): • Vehicle speed is above 4 mph (5 km/h). • The speed at which your vehicle is approaching the obstacle or oncom- ing vehicle exceeds 19 mph (30 km/h). • The front occupants are wearing a seat belt. l Pre-collision seat belts (linked to brake operation): • Vehicle speed exceeds 19 mph (30 km/h). • The system detects sudden braking or skidding. • The front occupants are wearing a seat belt. l Pre-collision brake assist: • Vehicle speed is above 19 mph (30 km/h). • The relative speed difference between your vehicle and another vehi- cle that is ahead of your vehicle, or the speed at which your vehicle is approaching an obstacle is greater than 19 mph (30 km/h). • The brake pedal is depressed. l Pre-collision braking: • The pre-collision braking off button is not pressed. • Vehicle speed is above 10 mph (15 km/h). • The relative speed difference between your vehicle and another vehi- cle that is ahead of your vehicle, or the speed at which your vehicle is approaching an obstacle is greater than 10 mph (15 km/h). 259 PRIUS_U (OM47685U) DVD 2-4. Using other driving systems n Conditions that may trigger the system even if there is no danger of collision l When there is an object by the roadside at the entrance to a curve l When passing an oncoming vehicle on a curve l When driving over a narrow iron bridge l When there is a metal object on the road surface l When driving on an uneven road surface l When passing an oncoming vehicle on a left-turn l When your vehicle rapidly closes on the vehicle in front l When a grade separation/interchange, sign, billboard, or other structure appears to be directly in the vehicle’s line of travel l When climbing a steep hill causes an overhead billboard, or other metal- lic structure to appear directly in the vehicle’s line of travel l When an extreme change in vehicle height occurs l When the axis of the radar is out of adjustment l When passing through certain toll gates 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 restricted position, stop the vehicle in a safe place, release the seat belt and refasten. n When there is a malfunction in the system Warning lights and/or warning messages will turn on or flash.

Using other driving systems CAUTION n 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. l 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 inattentive 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. l Assisting the driver in making correct judgment When attempting to estimate the likelihood 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 possi- bility of collision in any given situation. l Assisting the driver in taking action The pre-collision system’s braking assist feature is designed to help reduce the severity of a collision, and so only acts when the system has judged that a collision is unavoidable. This system by itself is not capable of automatically avoiding a collision or bringing the vehicle to a stop safety. 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. 262 PRIUS_U (OM47685U) DVD 2 2-4. Using other driving systems CAUTION n Handling the radar sensor Observe the following to ensure the pre-collision system can function effec- tively. l Keep the sensor and grille cover clean at all time. Clean the sensor and grille cover with a soft cloth so you do not mark or damage them. l 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 your Toyota dealer. l Do not disassemble the sensor. l Do not attach accessories or stickers to the sensor, grille cover or sur- rounding area. l Do not modify or paint the sensor and grille cover. n Limitations of the pre-collision system Do not rely on the pre-collision system. Always drive safely, taking care to observe your surroundings and checking for any obstacles or other road hazards. 263 PRIUS_U (OM47685U) DVD 2-5. Driving information Cargo and luggage Take notice of the following information about storage precau- tions, cargo capacity and load. l Stow cargo and luggage in the luggage compartment when- ever possible. Be sure all items are secured in place. l Be careful to keep the vehicle level. Placing the weight as far forward as possible helps maintain vehicle balance. l For better fuel economy, do not carry unnecessary weight. 264 PRIUS_U (OM47685U) DVD 2-5. Driving information Capacity and distribution Cargo capacity depends on the total weight of the occupants. (Cargo capacity) = (Total load capacity) — (Total weight of occupants) Steps for Determining Correct Load Limit— (1) Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehi- cle’s placard. (2) Determine the combined weight of the driver and passengers that will be riding in your vehicle. (3) Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs. (4) The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs. and there will be five 150 lb passengers in your vehicle, the amount of avail- able cargo and luggage load capacity is 650 lbs. (1400 - 750 (5 × 150) = 650 lbs.) (5) Determine the combined weight of luggage and cargo being (6) loaded on the vehicle. That weight may not safely exceed the available cargo and lug- gage load capacity calculated in Step 4. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. (→P. 269) Toyota does not recommend towing a trailer with your vehicle. Your vehicle is not designed for trailer towing. 265 PRIUS_U (OM47685U) DVD 2-5. Driving information Example on your vehicle Cargo capacity Total load capacity When 2 people with the combined weight of 366 lb. (166 kg) are riding in your vehicle, which has a total load capacity of 825 lb. (370 kg), the available amount of cargo and luggage load capacity will be as follows: 825 lb. — 366 lb. = 459 lb. (370 kg — 166 kg = 204 kg) In this condition, if 3 more passengers with the combined weight of 388 lb. (176 kg) get on, the available cargo and luggage load will be reduced as follows: 459 lb. — 388 lb. = 71 lb. (204 kg — 176 kg = 28 kg) As shown in the above example, if the number of occupants increases, the cargo and luggage load equaling the combined weight of the occupants who got on later, by an amount. In other words, if an increase in the number of occupants causes an excess of the total load capacity (combined weight of occupants plus cargo and luggage load), you must reduce the cargo and luggage on your vehicle. 266 PRIUS_U (OM47685U) DVD 2 2-5. Driving information CAUTION n Things that must not be carried in the luggage compartment The following things may cause a fire if loaded in the luggage compart- ment. l Receptacles containing gasoline l Aerosol cans n Storage precautions Observe the following precautions. Failing to do so may result in death or serious injury. l Do not place cargo or luggage in or on the following locations as the item may get under the brake or accelerator pedal and prevent the pedals from being depressed properly, block the driver’s vision, or hit the driver or passengers, causing an accident. • Driver’s feet • Front passenger or rear seats (when stacking items) • Luggage cover (if equipped) • Instrument panel • Dashboard • Auxiliary box or tray that has no lid l Secure all items in the occupant compartment, as they may shift and injure someone during sudden braking, sudden swerving or an acci- dent. l Never allow anyone to ride in the luggage compartment. It is not designed for passengers. They should ride in their seats with their seat belts properly fastened. Otherwise, they are much more likely to suffer death or serious injury, in the event of sudden braking, sudden swerv- ing or an accident. 267 PRIUS_U (OM47685U) DVD 2-5. Driving information CAUTION n Weight of the load l Do not exceed the maximum axle weight rating or the total vehicle weight rating. l Even if the total load of occupant’s weight and the cargo load is less than the total load capacity, do not apply the load unevenly. Improper loading may cause deterioration of steering or braking control which may cause death or serious injury. 268 PRIUS_U (OM47685U) DVD 2 2-5. Driving information Vehicle load limits Vehicle load limits include total load capacity, seating capacity, towing capacity and cargo capacity. n Total load capacity: 825 lb. (370 kg) Total load capacity means the combined weight of occupants, cargo and luggage. n Seating capacity: 5 occupants (Front 2, Rear 3) Seating capacity means the maximum number of occupants whose estimated average weight is 150 lb. (68 kg) per person.
