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 travelling ahead. 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 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 travelling 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 travelling ahead. Therefore, if there is ever any danger, the driver must take immediate and direct control of the vehicle and act appropriately in order to ensure the safety of all involved. ■To avoid inadvertent cruise control activation Switch the cruise control off using the “ON-OFF” button when not in use. SIENNA_OM_01999-08001_(U) 4 4-5. Using the driving support systems 271 WARNING ■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 ●When your vehicle is towing a trailer ■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. 266) 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 SIENNA_OM_01999-08001_(U) 272 4-5. Using the driving support systems WARNING ■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 seri- ous accident may result: ●When water or snow thrown up by the surrounding vehicles hinders the functioning of the sensor ●When your vehicle is pointing upwards (caused by a heavy load in the lug- gage compartment, etc.) ●When the road curves or when the lanes are narrow ●When steering wheel operation or your position in the lane is unstable ●When the vehicle ahead of you decelerates suddenly ■Handling the radar sensor Observe the following to ensure the cruise control system can function effectively: Otherwise, the system may not function correctly and could result in an accident. ●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 malfunction. If the sensor or surrounding area is subject to a strong impact, always have the area inspected and adjusted by a Toyota dealer. ●Do not disassemble the sensor. ●Do not attach accessories or stickers to the sensor, grille cover or sur- rounding area. ●Do not modify or paint the sensor and grille cover. ●Do not replace them with non-genuine parts.

Using the driving support systems ■The intuitive parking assist can be operated when ●The engine switch is in the “ON” position (vehicles without a smart key sys- tem) or IGNITION ON mode (vehicles with a smart key system). ●Front corner sensors: • The shift lever is not in P. • The vehicle speed is approximately 6 mph (10 km/h) or less. ●Rear corner and rear center sensors: The shift lever is in R. ■Intuitive parking assist display When an obstacle is detected while the rear view monitor system is in use, the warning indicator will appear in the upper corner of the screen even if the display setting has been set to off. ■Sensor detection information ●The sensor’s detection areas are limited to the areas around the vehicle’s bumper. ●Certain vehicle conditions and the surrounding environment may affect the ability of the sensor to correctly detect obstacles. Particular instances where this may occur are listed below. • There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this problem.) • The sensor is frozen. (Thawing the area will resolve this problem.) In especially cold weather, if a sensor is frozen the screen may show an abnormal display, or obstacles may not be detected. • The sensor is covered in any way. • The vehicle is leaning considerably to one side. • On an extremely bumpy road, on an incline, on gravel, or on grass • The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultra- sonic waves. • There is another vehicle equipped with parking assist sensors in the vicinity. • The sensor is coated with a sheet of spray or heavy rain. • The vehicle is equipped with a fender pole or wireless antenna. • The bumper or sensor receives a strong impact. • The vehicle is approaching a tall or curved curb. • In harsh sunlight or intense cold weather • The area directly under the bumpers is not detected. • If obstacles draw too close to the sensor. • A non-genuine Toyota suspension (lowered suspension etc.) is installed. • People may not be detected if they are wearing certain types of clothing. In addition to the examples above, there are instances in which, because of their shapes, signs and other objects may be judged by the sensor to be closer than they are. SIENNA_OM_01999-08001_(U) 4-5. Using the driving support systems 279 ●The shape of the obstacle may prevent the sensor from detecting it. Pay particular attention to the following obstacles: • Wires, fences, ropes, etc. • Cotton, snow and other materials that absorb sound waves • Sharply-angled objects • Low obstacles • Tall obstacles with upper sections projecting outwards in the direction of your vehicle ●The following situations may occur during use. • Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impossible. • Obstacles may not be detected if they are too close to the sensor. • There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the obstacle will come within the sensor’s detection areas before the display is shown and the beep sounds. • Thin posts or objects lower than the sensor may not be detected when approached, even if they have been detected once. • It might be difficult to hear beeps due to the volume of audio system or air flow noise of the air conditioning system. ■If the display flashes and a message is displayed P. 548 ■Certification (Canada only) This ISM device complies with Canadian ICES-001. WARNING ■When using the Intuitive parking assist-sensor Observe the following precautions. Failure to do so may result in the vehicle being unable to be driven safely and possibly cause an accident. ●Do not use the sensor at speeds in excess of 6 mph (10 km/h). ●The sensors’ detection areas and reaction times are limited. When moving forward or reversing, check the areas surrounding the vehicle (especially the sides of the vehicle) for safety, and drive slowly, using the brake to control the vehicle’s speed. ●Do not install accessories within the sensors’ detection areas. SIENNA_OM_01999-08001_(U) 280 4-5. Using the driving support systems NOTICE ■When using intuitive parking assist In the following situations, the system may not function correctly due to a sensor malfunction etc. Have the vehicle checked by your Toyota dealer. ●The intuitive parking assist operation display flashes, and a beep sounds when no obstacles are detected. ●If the area around a sensor collides with something, or is subjected to strong impact. ●If the bumper collides with something. ●If the display shows continuously without a beep. ●If a display error occurs, first check the sensor. ●If the error occurs even when there is no ice, snow or mud on the sensor, it is likely that the sensor is malfunctioning. ■Notes when washing the vehicle Do not apply intensive bursts of water or steam to the sensor area. Doing so may result in the sensor malfunctioning. SIENNA_OM_01999-08001_(U) 4 4-5. Using the driving support systems 281 Rear view monitor system The rear view monitor system assists the driver by displaying an image of the view behind the vehicle and guide lines while back- ing up, for example while parking. The screen illustrations used in this text are intended as examples, and may differ from the image that is actually displayed on the screen.  With guide function Refer to the “NAVIGATION AND MULTIMEDIA SYSTEM OWNER’S MANUAL”.  Without guide function The rear view monitor system will activate when the shift lever is in R. If you move the lever out of R, the rear view monitor system will be deactivated. When the shift lever is shifted to R and any mode button (such as “APPS”/“SETUP”) is pressed, the rear view monitor system is can- celed, and the screen is switched to the mode of the button that was pressed. SIENNA_OM_01999-08001_(U) 282 4-5. Using the driving support systems Using the rear view monitor system ■ Screen description The rear view monitor system screen will be displayed if the shift lever is shifted to R while the engine switch is in the “ON” position (vehicles without a smart key system) or IGNITION ON mode (vehi- cles with a smart key system). Vehicle width guide line The line indicates a guide path when the vehicle is being backed straight up. The displayed width is wider than the actual vehicle width. Vehicle center guide line These lines indicate the estimated vehicle center on the ground. Distance guide line The line shows distance behind the vehicle, a point approximately 1.5 ft. (0.5 m) (red) from the edge of the bumper. Distance guide line The line shows distance behind the vehicle, a point approximately 3 ft. (1 m) (blue) from the edge of the bumper.

The image on the rear view monitor system be adjusted. (P. 329) • The area displayed on the screen may vary according to vehicle orientation conditions. can • Objects which are close to either corner of the bumper or under the bumper cannot be dis- played. • The camera uses a special lens. The distance of the image that appears on the screen differs from the actual distance. Corners of bumper • Items which are located higher than the camera may not be displayed • If your vehicle is equipped with a backlit license plate, it may interfere on the monitor. with the display. SIENNA_OM_01999-08001_(U) 284 4-5. Using the driving support systems ■ Rear view monitor system camera The camera for the rear view monitor system located is above the license plate. ● Using the camera 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. ■ Differences between the screen and the actual road The distance guide lines and the vehicle width guide lines may not actually be parallel with the dividing lines of the parking space, even when they appear to be so. Be sure to check visually. The distances between the vehicle width guide lines and the left and right dividing lines of the parking space may not be equal, even when they appear to be so. Be sure to check visually. The distance guide lines give a distance guide for flat road sur- faces. In any of the following situations, there is a margin of error between the fixation guide lines on the screen and the actual dis- tance/course on the road. SIENNA_OM_01999-08001_(U) 4-5. Using the driving support systems 285 ● When the ground behind the vehicle slopes up sharply The distance guide lines will appear to be closer to the vehicle than the actual dis- tance. Because of this, objects will appear to be far- ther away than they actually are. In the same way, there will be a margin of error between the guide lines and the actual distance/course on the road. ● When the ground behind the vehicle slopes down sharply The distance guide lines will appear to be further from the vehicle than the actual dis- this, tance. Because of objects will appear to be closer than they actually are. In the same way, there will be a margin of error between the guide lines and the actual distance/course on the road. SIENNA_OM_01999-08001_(U) 286 4-5. Using the driving support systems ● When any part of the vehicle sags When any part of the vehicle sags due to the number of passengers or the distribu- tion of the load, there is a margin of error between the fixation guide lines on the screen and the actual dis- tance/course on the road. A margin of error ■ When approaching three-dimensional objects The distance guide lines are displayed according to flat surfaced objects (such as the road). It is not possible to determine the posi- tion of three-dimensional objects (such as vehicles) using the dis- tance guide lines. When approaching a three-dimensional object that extends outward (such as the flatbed of a truck), be careful of the following. ● Vehicle width guide lines the illustration, Visually check the surround- ings and the area behind the vehicle. In the case shown in the truck appears to be outside of the vehicle width guide lines and the vehicle does not look as if it hits the truck. However, the rear body of the truck may actually cross over the vehi- cle width guide lines. In real- ity if you back up as guided by the vehicle width guide lines, the vehicle may hit the truck. SIENNA_OM_01999-08001_(U) 4-5. Using the driving support systems 287 ● Distance guide lines Visually check the surround- ings and the area behind the vehicle.

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 ABS is activated. • The brake pedal may move down slightly after 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. ■Automatic reactivation of TRAC and VSC systems After turning the TRAC and VSC systems off, the systems will be automati- cally re-enabled in the following situations: ●When the engine switch is turned to the “LOCK” position (vehicles without a smart key system) or off (vehicles with a smart key system). ●If only the TRAC system is turned off, the TRAC will turn on when vehicle speed increases If both the TRAC and VSC systems are turned off, automatic re-enabling will not occur when vehicle speed increases. SIENNA_OM_01999-08001_(U) 294 4-5. Using the driving support systems ■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 engine off. The EPS system should return to normal within 10 minutes. ■Operating conditions of hill-start assist control (vehicles with a hill-start assist control system) When the following four conditions are met, the hill-start assist control will operate: ●The shift lever is in a position other than P or N (when starting off forward/ backward on an upward incline). ●The vehicle is stopped. ●The accelerator pedal is not depressed. ●The parking brake is not applied. ■Automatic system cancelation of hill-start assist control (vehicles with a hill-start assist control system) The hill-start assist control will turn off in any of the following situations: ●The shift lever is shifted to P or N. ●The accelerator pedal is depressed. ●The parking brake is applied. ●Approximately 2 seconds elapse after the brake pedal is released. WARNING ■The ABS does not operate effectively when ●The limits of tire gripping performance have been exceeded (such as excessively worn tires on a snow covered road). ●The vehicle hydroplanes while driving at high speed on wet or slick roads. ■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 following situations: ●When driving on dirt, gravel or snow-covered roads ●When driving with tire chains ●When driving over bumps in the road ●When driving over roads with potholes or uneven surfaces SIENNA_OM_01999-08001_(U) 4-5. Using the driving support systems 295 WARNING ■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. Drive the vehicle carefully in conditions where stability and power may be lost. ■Hill-start assist control (vehicles with a hill-start assist control system) ●Do not overly rely on hill-start assist control. Hill-start assist control may not operate effectively on steep inclines and roads covered with ice. ●Unlike the parking brake, hill-start assist control is not intended to hold the vehicle stationary for an extended period of time. Do not attempt to use hill-start assist control to hold the vehicle on an incline, as doing so may lead to an accident. ■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. ■When the TRAC/VSC systems are turned off Be especially careful and drive at a speed appropriate to the road condi- tions. As these are the systems to help ensure vehicle stability and driving force, do not turn the TRAC/VSC systems off unless necessary. ■Replacing tires Make sure that all tires are of the specified size, brand, tread pattern and total load capacity. In addition, make sure that the tires are inflated to the recommended tire inflation pressure level.

Using the driving support systems PCS (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 automatically engaged to lessen impact as well as vehicle dam- age. ◆ Pre-collision warning When a high possibility of a frontal collision is detected, the pre-collision system warning light flashes, a buzzer sounds and a message is shown on the multi-information display to urge the driver to take evasive action. ◆ 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. 31) However, when the VSC system is disabled, the system will not operate in the event of skidding. ◆ Pre-collision brake assist When there is a high possibility of a frontal collision, the system applies greater braking force in relation to how strongly the brake pedal is depressed. The system may not warn the driver using a warning light, warning display and buzzer when the system detects and judges braking operations. : If equipped SIENNA_OM_01999-08001_(U) 4 4-5. Using the driving support systems 297 ◆ 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-colli- sion braking can be disabled using the pre-collision braking off switch. Disabling pre-collision braking Pre-collision braking disabled Pre-collision braking enabled The pre-collision system warning light will turn on when pre-collision braking is disabled. Radar sensor The radar sensor detects vehi- cles or other obstacles on or near the road ahead and determines whether a collision is imminent based on the position, speed, and heading of the obstacles.

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 judgment 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. SIENNA_OM_01999-08001_(U) 302 4-5. Using the driving support systems WARNING ■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 front grille clean at all times. Clean the sensor and front grille 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 Toy- ota dealer. ●Do not disassemble the sensor. ●Do not attach accessories or stickers to the sensor, grille or surrounding area. ●Do not modify or paint the sensor and grille cover.

Driving tips 311 Winter driving tips Carry out the necessary preparations and inspections before driving the vehicle in winter. Always drive the vehicle in a man- ner appropriate to the prevailing weather conditions. Preparation for winter ● Use fluids that are appropriate to the prevailing outside tempera- tures. • Engine oil • Engine coolant • Washer fluid ● Have a service technician inspect the condition of the 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. 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 accu- mulated on the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes. ● Remove any snow or mud from the bottom of your shoes before getting in the vehicle. SIENNA_OM_01999-08001_(U) 312 4-6. Driving tips 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 con- ditions. When parking the vehicle Park the vehicle and move the shift lever to P without setting the park- ing brake. The parking brake may freeze up, preventing it from being released. If necessary, block the wheels to prevent inadvertent sliding or creeping. Selecting tire chains Use the tire chains of correct size and type. Use SAE Class “S” type radial tire chains, with the exception of radial cable chains or V-bar type chains. Regulations on the use of tire chains Regulations regarding the use of tire chains vary depending on loca- tion and type of road. Always check local regulations before installing chains. ■Tire chain installation Observe the following precautions when installing and removing chains. ●Install and remove tire chains in a safe location. ●Install tire chains on the front tires only. Do not install tire chains on the rear tires. ●Install tire chains on front tires as tightly as possible. Retighten chains after driving 1/4 - 1/2 mile (0.5 - 1.0 km). ●Install tire chains following the instructions provided with the tire chains. SIENNA_OM_01999-08001_(U) 4 4-6. Driving tips 313 WARNING ■Driving with snow tires Observe the following precautions to reduce the risk of accidents. Failing to do so may result in a loss of vehicle control and cause death or serious injury. ●Use tires of the specified size. ●Maintain the recommended level of air pressure. ●Do not drive in excess of 75 mph (120 km/h), regardless of the type of snow tires being used. ●Use snow tires on all, not just some wheels. ■Driving with tire chains Observe the following precautions to reduce the risk of accidents. Failing to do so may result in the vehicle being unable to be driven safely, and may cause death or serious injury. ●Do not drive in excess of the speed limit specified for the tire chains being used or 30 mph (50 km/h), whichever is lower. ●Avoid driving on bumpy road surfaces or over potholes. ●Avoid sudden acceleration, abrupt steering, sudden braking and shifting operations that cause sudden engine braking. ●Slow down sufficiently before entering a curve to ensure that vehicle con- trol is maintained. NOTICE ■Repairing or replacing snow tires Request repairs or replacement of snow tires from Toyota dealers or legiti- mate tire retailers. This is because the removal and attachment of snow tires affects the opera- tion of the tire pressure warning valves and transmitters. ■Fitting tire chains The tire pressure warning valves and transmitters may not function correctly when tire chains are fitted.
