Tires Replace or rotate tires in accordance with maintenance schedules and treadwear. Tires Checking Checking tires Check if the treadwear indicators are showing on the tires. Also check the tires for uneven wear, such as excessive wear on one side of the tread. Check the spare tire condition and pressure if not rotated. New tread Worn tread Treadwear indicator The location of treadwear indicators is shown by a “ TWI” or “ ” mark, etc., molded into the sidewall of each tire. Replace the tires if the treadwear indicators are showing on a tire. Note: When to replace your vehicle’s tires Tires should be replaced if: The treadwear indicators are showing on a tire. You have tire damage such as cuts, splits, cracks deep enough to expose the fabric, and bulges indicating internal damage A tire goes flat repeatedly or cannot be properly repaired due to the size or location of a cut or other damage If you are not sure, consult your Toyota dealer. Tire life Any tire over 6 years old must be checked by a qualified technician even if it has seldom or never been used or damage is not obvious. Low profile tires (vehicles with 195/50R19 tires) Generally, low profile tires will wear more rapidly and tire grip performance will be reduced on snowy and/or icy roads when compared to standard tires. Be sure to use snow tires on snowy and/or icy roads and drive carefully at a speed appropriate for road and weather conditions. Maximum load of tire Check that the maximum load of the replacement tire is greater than 1/2 of the Gross Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is greater. For the GAWR, see the Certification Label. For the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire. (Tire information) Tire types Summer tiresSummer tires are high-speed performance tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction performance as snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For driving on snow-covered roads or icy roads, the use of snow tires is recommended. When installing snow tires, be sure to replace all four tires. All season tiresAll season tires are designed to provide better traction in snow and to be adequate for driving in most winter conditions as well as for use year-round. All season tires, however, do not have adequate traction performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in acceleration and handling performance compared with summer tires in highway driving. Snow tiresFor driving on snow-covered roads or icy roads, we recommend using snow tires. If you need snow tires, select tires of the same size, construction and load capacity as the originally installed tires. Since your vehicle has radial tires as original equipment, make sure your snow tires also have radial construction. Do not install studded tires without first checking local regulations for possible restrictions. Snow tires should be installed on all wheels. (Preparation for winter) If the tread on snow tires wears down below 0.16 in. (4 mm) The effectiveness of the tires as snow tires is lost. Warning: When inspecting or replacing tires Observe the following precautions to prevent accidents.Failure to do so may cause damage to parts of the drivetrain as well as dangerous handling characteristics, which may lead to an accident resulting in death or serious injury. Do not mix tires of different makes, models or tread patterns.Also, do not mix tires of remarkably different treadwear. Do not use tire sizes other than those recommended by Toyota. Do not mix differently constructed tires (radial, bias-belted or bias-ply tires). Do not tow if your vehicle has a compact spare tire installed. Do not mix summer, all season and snow tires. Do not use tires that have been used on another vehicle.Do not use tires if you do not know how they were used previously. Notice: Driving on rough roads Take particular care when driving on roads with loose surfaces or potholes.These conditions may cause losses in tire inflation pressure, reducing the cushioning ability of the tires. In addition, driving on rough roads may cause damage to the tires themselves, as well as the vehicle’s wheels and body. Low profile tires (vehicles with 195/50R19 tires) Low profile tires may cause greater damage than usual to the tire wheel when sustaining impact from the road surface. Therefore, pay attention to the following: Be sure to use proper tire inflation pressure. If tires are under-inflated, they may be damaged more severely. Avoid potholes, uneven pavement, curbs and other road hazards. Failure to do so may lead to severe tire and wheel damage. If tire inflation pressure of each tire becomes low while driving Do not continue driving, or your tires and/or wheels may be ruined. Tires Rotating tires Tire rotation Rotate the tires in the order shown. To equalize tire wear and extend tire life, Toyota recommends that tire rotation is carried out at the same interval as tire inspection. Do not fail to initialize the tire pressure warning system after tire rotation. Front Note: When rotating the tires Make sure that the power switch is off. If the tires are rotated while the power switch is in ON, the tire position information will not be updated. If this accidentally occurs, either turn the power switch to off and then to ON, or initialize the system after checking that the tire pressure is properly adjusted. Flat tire Tire pressure warning system Multi-information display Tire pressure Tire inflation pressure Tire inflation pressure display function Tire pressure warning system Tire pressure warning system Function Tires Tire inflation pressure display function Tires Tire pressure warning system Tire pressure warning system Your vehicle is equipped with a tire pressure warning system that uses tire pressure warning valves and transmitters to detect low tire inflation pressure before serious problems arise. The tire pressure warning system of this vehicle adopts a 2-type warning system. When “ Adjust Pressure” is displayed (Normal Warning) The tire pressure warning light comes on and a buzzer sounds when the tire inflation pressure becomes low due to natural air leakage or outside temperature. (Ways of coping: Tire pressure warning light (warning buzzer), Tires and wheels) When “ Immediately Check tire when Safe” is displayed (Emergency Warning) The tire pressure warning light comes on and a buzzer sounds when the tire inflation pressure becomes low suddenly due to a blowout. (Ways of coping: Tire pressure warning light (warning buzzer), If you have a flat tire (vehicles without spare tire), If you have a flat tire (vehicles with spare tire)) However, the system may not be able to detect sudden tire ruptures (bursting, etc.). The tire pressure detected by the tire pressure warning system can be displayed on the multi-information display. (Multi-information display) The illustration used is intended as an example, and may differ from the image that is actually displayed on the multi-information display. How to change the unit Park the vehicle in a safe place and turn the power switch off. Changing the unit cannot be performed while the vehicle is moving. Start the hybrid system. Use the meter control switches (Changing the display) to select (Menu icons). Use the meter control switches to select , then press and hold . Use the meter control switches to select “ TPWS setting”, then press . Use the meter control switches to select “ Pressure unit setting”, then press . Use the meter control switches to select the desired unit and then press . Note: Routine tire inflation pressure checks The tire pressure warning system does not replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily vehicle checks. Tire inflation pressure It may take a few minutes to display the tire inflation pressure after the power switch is turned to ON.It may also take a few minutes to display the tire inflation pressure after inflation pressure has been adjusted. Tire inflation pressure changes with temperature. The displayed values may also be different from the values measured using a tire pressure gauge. Situations in which the tire pressure warning system may not operate properly In the following cases, the tire pressure warning system may not operate properly. If non-genuine Toyota wheels are used. A tire has been replaced with a tire that is not an OE (Original Equipment) tire. A tire has been replaced with a tire that is not of the specified size. Tire chains etc. are equipped. If a window tint that affects the radio wave signals is installed. If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel housings. If the tire inflation pressure is extremely higher than the specified level. If wheel without tire pressure warning valves and transmitters are used. If the ID code on the tire pressure warning valves and transmitters is not registered in the tire pressure warning computer. Performance may be affected in the following situations. Near a TV tower, electric power plant, gas station, radio station, large display, airport or other facility that generates strong radio waves or electrical noise When carrying a portable radio, cellular phone, cordless phone or other wireless communication device If tire position information is not correctly displayed due to the radio wave conditions, the display may be corrected by changing the location of the vehicle as the radio wave conditions may change. When the vehicle is parked, the time taken for the warning to start or go off could be extended. When tire inflation pressure declines rapidly for example when a tire has burst, the warning may not function. Warning performance of the tire pressure warning system The warning of the tire pressure warning system will change in accordance with driving conditions. For this reason, the system may give a warning even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when the system was initialized. Tire pressure warning system Installing tire pressure warning valves and transmitters Installing tire pressure warning valves and transmitters When replacing tires or wheels, tire pressure warning valves and transmitters must also be installed. When new tire pressure warning valves and transmitters are installed, new ID codes must be registered in the tire pressure warning computer. (Registering ID codes) Note: When replacing the tires and wheels If the ID code of the tire pressure warning valve and transmitter is not registered, the tire pressure warning system will not work properly. In this case, after driving for about 20 minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a system malfunction. Notice: Repairing or replacing tires, wheels, tire pressure warning valves, transmitters and tire valve caps When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters, contact your Toyota dealer as the tire pressure warning valves and transmitters may be damaged if not handled correctly. Make sure to install the tire valve caps. If the tire valve caps are not installed, water could enter the tire pressure warning valves, corrode the valve, and cause sticking and air leaks. When replacing tire valve caps, do not use tire valve caps other than those specified. The cap may become stuck. To avoid damage to the tire pressure warning valves and transmitters When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact your Toyota dealer or other qualified service shop as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when replacing the tire.

When wheel position registration is complete, a message indicating that registration has been completed and the inflation pressure of each tire will be displayed on the multi-information display. Even if it is not possible to drive continuously at approximately 25 mph (40 km/h) or more, registration can be completed by driving for a long time. However, if registration does not complete after driving for 1 hour or more, park the vehicle in a safe place and leave it with the power switch in ON for approximately 15 minutes or more, and then perform the driving procedure again. Note: When performing wheel position registration Normally, wheel position registration can be completed within approximately 30 minutes. Wheel position registration is performed while driving at a vehicle speed of approximately 25 mph (40 km/h) or more. Wheel position registration procedure If the power switch is turned off while registering the wheel position, the next time the power switch is turned to ON, the wheel position registration will resume and it will not be necessary to restart the procedure. While the position of each wheel is being determined and the inflation pressures are not being displayed, if the inflation pressure of a tire drops, the tire pressure warning light will come on. If the wheel position cannot be registered easily In the following situations, wheel position registration may take longer than usual to be completed or may not be possible. Vehicle is not driven at approximately 25 mph (40 km/h) or more Vehicle is driven on unpaved roads If wheel position registration does not complete after driving for 1 hour or more, park the vehicle in a safe place for approximately 15 minutes and then drive the vehicle again. If the vehicle is reversed during wheel position registration, all data collected until then will be cleared. Perform driving again. Tire pressure warning system Setting the tire pressure Setting the tire pressure In the following situations, it will be necessary to perform the tire inflation pressure setting procedure of the tire pressure warning system. When the specified tire inflation pressure has changed, such as due to carried load, etc. When the tire inflation pressure is changed such as when the tire size is changed. If the tire inflation pressure has been adjusted to the specified level, perform the tire inflation setting procedure by selecting specified inflation pressure on the multi-information display. When the tire inflation pressure is to be other than specified, such as when tires other than the specified size are used, etc., set the tire inflation pressure using the current pressure. Make sure to adjust the tire inflation pressure of each tire to the appropriate level before performing tire pressure setting.
