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 pr obable that you have a flat tire. Check the tires.

compact spare tire after the tire pressure warning light comes on, the
light remains on.

CAUTION
■Replacing a flat tire
●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 po ssible 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 wh eel, 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)
■When stowing the flat tire
●Make sure the rear seats are in their original position.
● Secure it using a tire tie-down belt. Otherwise, the flat tire may fly out in
case of the sudden braking or an accident, resulting in death or serious
injury.

Overheating
If you observe the following, your vehicle may be overheating:
●The high engine coolant temperature warning light flashes or comes on
or a loss of power is experienced.
● Steam comes out from under the hood.
CAUTION
■To prevent an accident or injury when inspecting under the hood of
your vehicle
●If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
● Keep hands and clothing away from the fan and drive belt while the engine
is running.
● Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.

sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. ( →P. 347)
