Using other driving systems ■ Canceling and resuming the speed control the Pulling the lever toward you cancels the cruise control. The speed setting is also can- celed when the brakes are applied. Pushing lever up resumes the cruise control and returns vehicle speed to the set speed. Resuming is available when the vehicle speed is more than approximately 25 mph (40 km/h). ITO24P127 274 2-4. Using other driving systems 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. 275 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. 276 2 2-4. Using other driving systems 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 277 2-4. Using other driving systems Selecting conventional constant speed control mode Constant speed control mode differs from vehicle-to-vehicle distance control mode. When constant speed mode is selected, your vehicle will maintain a set speed regardless of whether or not there are other vehicles in the lane ahead. Press the “ON-OFF” button to activate the cruise control. Press the button again to deacti- vate the cruise control. Switch to constant speed con- trol mode. (Push the lever forward and hold for approximately 1 sec- ond.) Cruise control indicator will come on. When in constant speed control mode, to return to vehicle-to-vehi- cle distance control mode, push the lever forward again and hold for approximately 1 second. After the desired speed has been set, it is not possible to return to vehicle-to-vehicle distance con- trol mode. 278 2-4. Using other driving systems If the “POWER” switch is turned off and then turned to ON mode again, the vehicle will automati- cally return to vehicle-to-vehicle distance control mode.

After acceleration, the set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehicle speed may decrease below the set speed in order to maintain the distance to the vehicle ahead. ■Set speed The set speed may be unsustainable depending on driving circumstances. 279 2-4. Using other driving systems ■Automatic cancelation of vehicle-to-vehicle distance control Vehicle-to-vehicle distance control driving is automatically canceled in the following situations: ●Actual vehicle speed falls below approximately 25 mph (40 km/h). ●Enhanced VSC is activated. ●The sensor cannot operate correctly because it is covered in some way. ●The windshield wipers are operating at high speed (when the wiper switch is set to the high speed windshield wiper operation position). If vehicle-to-vehicle distance control driving is automatically canceled for any other reason, there may be a malfunction in the system. Contact your Toyota dealer. ■Automatic cancelation of constant speed control The cruise control will stop maintaining the vehicle speed in the following sit- uations: ●Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehicle speed. At this time, the memorized set speed is not retained. ●Vehicle speed falls below approximately 25 mph (40 km/h). ●Enhanced VSC is activated. ■Radar sensor and grille cover Always keep the sensor and grille cover clean to ensure that the vehicle-to- vehicle distance control operates properly. (Some obstructions, such as snow, ice and plastic objects, cannot be detected by the obstruction sensor.) Dynamic radar cruise control (vehicle-to-vehicle distance control mode) will be canceled if dirt is detected. (Constant speed control mode can be used). Grille cover Radar sensor 280 2 2-4.

Using other driving systems 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. 282 2 2-4. Using other driving systems CAUTION ■To avoid inadvertent cruise control activation Switch the cruise control off using the “ON-OFF” button when not in use. ■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 or 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 is heard often ●During emergency towing 283 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. 277) 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 284 2 2-4. Using other driving systems 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 has moved out of position, the system may malfunction or operate incorrectly. 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. 285 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. 270) 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. 286 ∗: If equipped 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. “LKA” indicator will come on. Press the switch again to turn the LKA system off. 287 2-4. Using other driving systems ■ Operating conditions for each function “LKA” switch On Cruise control (vehicle-to-vehicle distance control mode) Off On (While cruising in vehi- cle-to-vehicle distance control mode with the set vehicle speed approx. 45 mph [approx. 70 km/h] or less) On (While cruising in vehi- cle-to-vehicle distance control mode with the set vehicle speed approx. 50 mph [approx. 75 km/h] or more) Lane departure warning function*1 Available Lane keeping assist function*2 Not available Available Not available Available Available *1: Vehicle speed is between about 30 and 124 mph (50 and 200 km/h). *2: Vehicle speed is between about 50 and 112 mph (75 and 180 km/h). 288 2 2-4. Using other driving systems Indication on the multi-information display While the LKA system is on, the lane line display and steering wheel display (in case of lane keeping assist function) are shown on the multi-information display to inform that the LKA system is on. Steering wheel display The lane keeping assist function is active. Dynamic radar cruise control display Lane line display When thin lines are shown: A lane marking is not recognized by the system, or the LKA system functions are temporarily can- celed. When solid lane lines are shown: The lane departure warning func- tion is active. 289 2-4. Using other driving systems ■Temporary cancelation 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. However, the lane keeping assist function will not resume even after the brake pedal is released because depressing the brake pedal also can- cels the dynamic radar cruise control. (Only lane departure warning func- tion will resume.) ●The vehicle speed deviates from the operating range of the LKA system functions. ●When the lane lines cannot be recognized while driving. ●The wiper operates continuously. ■When the lane departure warning function is activated The lane departure warning function will be temporarily canceled and will not resume until a few seconds elapse after it is activated. 290 2 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. ■Warning lights and warning messages for LKA Warning lights and messages are used to indicate a system malfunction or to inform the driver of the need for caution while driving. (→P. 496, 510) 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. 291 2-4. Using other driving systems CAUTION ■Turn the LKA off while driving in any of the following conditions 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, snow chains, a spare tire, or similar equip- ment. ●When driving with non-standard parts or aftermarket equipment installed. (including modified tires and suspensions, etc.) ●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 there are wheel ruts, icy trademarks, etc. or if snow remains on the road surface. ●When there are shadows on the road running parallel with lane markers, or if a shadow covers the lane markers. ●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. ●When driving on winding roads or roads that are rough or uneven. 292 2 2-4. Using other driving systems NOTICE ■In the following situations, the LKA will not work, or will not perform reliably: ●When lane markers are interrupted or are not present, such as before a tollbooth. ●When lane markers are only on one side of the road. ●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 broken, “Botts’ dots”, or “Raised pavement marker”. ●When lane markers are obscured or partially obscured by sand, dirt, etc. ●When driving on a particularly bright road surface, such as concrete. ●When driving on a road surface that is bright due to reflected light. 293 2-4. Using other driving systems NOTICE ●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 pavement lane markers are difficult to see due to rain, snow, fog, etc. ●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 is reduced due to dirt on the lenses, or when the headlights are misaligned. ●When driving with a strong crosswind. 294 NOTICE ■Camera sensor 2-4. Using other driving systems 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 attach a sticker or other items to the windshield near the camera sensor. ●When adjusting the rear view mirror, make sure that it does not block the camera lens. ●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 change the installation position of the camera sensor or remove it. The direction of the camera sensor is precisely adjusted. ●Do not subject the camera sensor to strong impact or force, and do not disassemble the camera sensor. 295 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. 296 2-4. Using other driving systems ■ Hill-start assist control →P. 301 ■ PCS (Pre-Collision System) (if equipped) →P. 303 When the TRAC/VSC/ABS systems are operating The slip indicator light will flash while the TRAC/VSC/ABS sys- tems are operating. 297 2-4. Using other driving systems ■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. ■Electric power steering system warning light (warning buzzer) →P. 501 298 2 2-4. Using other driving systems CAUTION ■The ABS does not operate effectively when ●Tires with inadequate gripping ability are used (such as excessively worn tires on a snow covered road). ●The vehicle hydroplanes while driving at high speed on 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 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 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. 299 2-4. Using other driving systems 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. 300 2 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 an 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. ■Hill-start assist control can be operated when ●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 ●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. 301 2-4. Using other driving systems ■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. 302 2 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. 111) 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. ∗: If equipped 303 Pre-collision braking enabled Pre-collision braking disabled The “PCS” warning light will turn on when pre-collision braking is disabled. The radar sensor detects vehi- cles or other obstacles on or near the road ahead and deter- mines whether a collision is imminent based on the position, speed, and heading of the obsta- cles. 2-4.

Using other driving systems ■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: • 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). • The pre-collision braking off switch is not pressed. 305 2-4. Using other driving systems ■Conditions that may trigger the system even if there is no possibility of a collision ●When there is an object by the roadside at the entrance to a curve ●When passing an oncoming vehicle on a curve ●When driving over a narrow iron bridge ●When there is a metal object on the road surface ●When driving on an uneven road surface (nose up, nose down) ●When passing an oncoming vehicle on a left-turn ●When your vehicle rapidly closes on the vehicle in front ●When a grade separation/interchange, sign, billboard, or other structure appears to be directly in the vehicle’s line of travel ●When the steep angle of the road causes a metal object located beneath the road surface to be seen ahead of the vehicle ●When an extreme change in vehicle height occurs ●When the axis of the radar is out of adjustment ●When passing through certain toll gates ●When passing through an overpass When the system is activated in the situations described above, there is also a possibility that the seat belts will retract quickly and the brakes will be applied with a force greater than normal. When the seat belt is locked in the retracted position, stop the vehicle in a safe place, release the seat belt and refasten it. 306 2 2-4. Using other driving systems ■Obstacles not detected The sensor cannot detect plastic obstacles such as traffic cones. There may also be occasions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees, or snowdrifts. ■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 ■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 Warning lights and/or warning messages will turn on or flash.

Using other driving systems CAUTION ■Limitations of the pre-collision system Do not overly rely on the pre-collision system. Always drive safely, taking care to observe your surroundings and checking for any obstacles or other road hazards. Failure to do so may cause an accident resulting in death or serious injury. ■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 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. ●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 possi- bility 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 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 safely. 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. 309 2-4. Using other driving systems CAUTION ■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 lug- gage compartment 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 effec- tively: ●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 has moved out of position, the system may malfunction or operate incorrectly. 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. 310 2-5. Driving information Cargo and luggage Take notice of the following information about storage precau- tions, cargo capacity and load: ● Stow cargo and luggage in the luggage compartment whenever possible. ● Be sure all items are secured in place. ● To maintain vehicle balance while driving, position luggage evenly within the luggage compartment. ● For better fuel economy, do not carry unnecessary weight. 311 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 vehicle’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 lug- gage 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 available cargo and luggage load capacity is 650 lbs. (1400 − 750 (5 × 150) = 650 lbs.) (5) Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. (6) 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. 316) Toyota does not recommend towing a trailer with your vehicle. Your vehicle is not designed for trailer towing. 312 2-5. Driving information Example based 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 830 lb. (375 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 example above, if the number of occupants increases, the cargo and luggage load will be reduced by an amount that equals the increased weight due to the additional occupants. 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. 313 2-5. Driving information CAUTION ■Things that must not be carried in the luggage compartment The following things may cause a fire if loaded in the luggage compart- ment: ●Receptacles containing gasoline ●Aerosol cans ■Storage precautions Observe the following precautions. Failure to do so may result in death or serious injury. ●Stow cargo and luggage in the luggage compartment whenever possi- ble. ●Do not stack cargo and luggage in the luggage compartment higher than the seatbacks. Such items may be thrown about and possibly injure people in the vehicle in the event of sudden braking or in an accident. ●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: • At the feet of the driver • On the front passenger or rear seats (when stacking items) • On the luggage cover (if equipped) • On the instrument panel • On the dashboard 314 2-5. Driving information CAUTION ●Secure all items in the occupant compartment, as they may shift and injure someone in the event of an accident or sudden braking. ●When you fold down the rear seats, long items should not be place directly behind the front seats. ●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 bodily injury, in the event of sudden braking or an accident. ■Capacity and distribution ●Do not exceed the maximum axle weight rating or the total vehicle weight rating. ●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. 315 2-5. Driving information Vehicle load limits Vehicle load limits include total load capacity, seating capacity, towing capacity and cargo capacity. ■ Total load capacity: 825 lb. (370 kg) Total load capacity means the combined weight of occupants, cargo and luggage. ■ 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. ■ Towing capacity Toyota does not recommend towing a trailer with your vehicle. ■ Cargo capacity Cargo capacity may increase or decrease depending on the weight and the number of occupants. ■Total load capacity and seating capacity These details are also described on the tire and loading information label. (→P. 447) CAUTION ■Overloading the vehicle Do not overload the vehicle. It may not only cause damage to the tires, but also degrade steering and braking ability, resulting in an accident. 316 2 2-5. Driving information Winter driving tips Carry out the necessary preparations and inspections before driving the vehicle in winter. Always drive the vehicle in a manner appropri- ate to the prevailing weather conditions. ■ Pre-winter preparations ● Use fluids that are appropriate to the prevailing outside tem- peratures. • 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. 317 2-5. Driving information ■ Before driving the vehicle 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 immediately 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 snow or mud from the bottom of your shoes before getting in the vehicle. ■ When driving the vehicle Accelerate the vehicle slowly, keep a safe distance between you and the vehicle ahead, and drive at a reduced speed suitable to road conditions. ■ When parking the vehicle Park the vehicle and shift the shift position to P and block the wheel under the vehicle without setting the parking brake. The parking brake may freeze up, preventing it from being released. If necessary, block the wheels to prevent inadvertent sliding or creeping. 318 2
