Customization that can be configured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 363) However, Toyota recommends that the seat

when seat belts are not fastened.
WARNING
■ When the electric power steerin g 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 (vehicles with a tire
pressure warning system)
Be sure to observe the following precautions. Failure to do so could
cause a loss of vehicle control and result in death or serious injury.
●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 pres-
sure 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 deteriorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur (vehicles with a tire
pressure warning system)

WARNING
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Do not try to remove the wheel ornament by hand. Take due care inhandling the ornament to avoid unexpected personal injury.
• Do not touch the disc wheels or the area around the brakes immedi-
ately 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.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting in 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 ends facing inward. ( P. 266)

on another vehicle.
●Do not use more than one compact spare tire simultaneously.
●Replace the compact spare tire with a standard tire as soon as possi-
ble.
●Avoid sudden acceleration, abrupt steering, sudden braking and shift-
ing operations that cause sudden engine braking.
■When storing the compact spare tire
Be careful not to catch fingers or other body parts between the compact
spare tire and the body of the vehicle.
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in
their storage location to reduce the possibility of personal injury during a
collision or sudden braking.
■When the compact spare tire is attached

tems may not operate correctly:
●ABS
●Brake assist
●VSC
●TRAC
●PCS (Pre-Collision System) (if equipped)
●LDA (Lane Departure Alert) (if equipped)
●Automatic High Beam (if equipped)
●Cruise control (if equipped)

■Speed limit when using the compact spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a compact
spare tire is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Fail-
ure to observe this precaution may lead to an accident causing death or
serious injury.
■When stowing the flat tire
●Make sure the rear seats are in their original position.
