SIENNA_OM_OM45483U_(U)

5-2. Steps to take in an emergency

CAUTION

■When the electric power steering system warning light comes on

The steering wheel may become extremely heavy. If the steering wheel becomes heavier than usual when operating, hold firmly and operate using more force than usual.

■If the tire pressure warning light comes on

Be sure to observe the following precautions. Failure to do so could cause loss of vehicle control and result in death or serious injury. ●Vehicles with standard tires:

• Stop your vehicle in a safe place as soon as possible. Adjust the

tire inflation pressure immediately.

• If the tire pressure warning light comes on even after tire inflation pressure adjustment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change it with the spare tire and have the flat tire repaired by the nearest Toyota dealer.

• Avoid abrupt maneuvering and braking. If the vehicle tires deterio-

rate, you could lose control of the steering wheel or the brakes.

●Vehicles with run-flat tires:

• Decelerate to the lowest appropriate speed as soon as possible.

Do not drive over 50 mph (80 km/h).

• Check and adjust the tire inflation pressure immediately. • If the tire pressure warning light comes on even after tire inflation pressure adjustment, it is probable that you have a flat tire. Have the tire replaced by the nearest Toyota dealer.

• Avoid abrupt maneuvering and braking. If the vehicle tires deterio-

rate, you could lose control of the steering wheel or the brakes.

755

SIENNA_OM_OM45483U_(U)

5-2. Steps to take in an emergency

CAUTION

■If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.

■Maintenance of the tires

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label (tire and load information label). (If your vehicle has tires of a differ- ent size than the size indicated on the vehicle placard or tire inflation pressure label [tire and load information label], you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS-tire pressure warning system) that illuminates a low tire pressure telltale (tire pressure warning light) when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale (tire pressure warning light) illumi- nates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under- inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. Please note that the TPMS (tire pressure warning system) is not a sub- stitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale (tire pressure warning light).

756

SIENNA_OM_OM45483U_(U)

5-2. Steps to take in an emergency

CAUTION

Your vehicle has also been equipped with a TPMS (tire pressure warning system) malfunction indicator to indicate when the system is not operat- ing properly. The TPMS (tire pressure warning system) malfunction indi- cator is combined with the low tire pressure telltale (tire pressure warning light). When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illumi- nated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illumi- nated, the system may not be able to detect or signal low tire pressure as intended. TPMS (tire pressure warning system) malfunctions may occur for a vari- ety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS (tire pressure warning system) from functioning properly. Always check the TPMS (tire pres- sure warning system) malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alter- nate tires and wheels allow the TPMS (tire pressure warning system) to continue to function properly.

NOTICE

■Precaution when installing a different tire

When a tire of a different specification or maker is installed, the tire pres- sure warning system may not operate properly.

5-2. Steps to take in an emergency If you have a flat tire (vehicles with run-flat tires)

You can continue driving a vehicle with run-flat tires even if any tire goes flat. In this case, slow down and drive with extra caution. ■ Run-flat tires (A “RFT” or “DSST” mark is molded on the

sidewall)

Take your vehicle to the near- est Toyota dealer or autho- rized tire dealer as soon as possible if any tire goes flat.

The vehicle can be driven for a maximum of 100 miles (160 km) at a speed below 50
mph (80 km/h) after the tire pressure warning light comes on. (P. 747)

CAUTION

■Replacing a flat tire

●Observe the following precautions.

Failure to do so may result in serious injury: • Do not touch the disc wheels or the area around the brakes imme-

diately after the vehicle has been driven. After the vehicle has been driven the disc wheels and the area around the brakes will be extremely hot. Touching these areas with hands, feet or other body parts while changing a tire, etc. may result in burns.

• Remove the spare tire before jacking up the vehicle. If the spare tire is removed after jacking up the vehicle, the tire carrier and the spare tire may interfere with the jack and cause a serious accident.

●Failure to follow these precautions could cause the wheel nuts to

loosen and the tire to fall off, resulting on death or serious injury. • Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103 N•m, 10.5 kgf•m) as soon as possible after changing wheels. • When installing a tire, only use wheel nuts that have been specifi-

cally designed for that wheel.

• If there are any cracks or deformations in the bolt screws, nut threads or bolt holes of the wheel, have the vehicle inspected by your Toyota dealer.

• When installing the wheel nuts, be sure to install them with the

tapered end facing inward. (P. 705)
