Tire rotation
Vehicles with a spare tire of a different wheel type from the
installed tires
Rotate the tires in the order
shown.
To equalize tire wear and
extend tire life, Toyota recom-
mends that tire rotation is
carried out at the same inter-
val as tire inspection.
■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.
(  P. 733)
Vehicles with compact spare tire : The compact spare tire is not
equipped with the tire pressure warning valve and transmitters.

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 brak ing. If the vehicle tires deterio-
rate, you could lose control of th e steering wheel or the brakes.
●Vehicles with run-flat tires:
• Decelerate to the lowest appropr iate speed as soon as possible.
Do not drive over 55 mph (90 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 brak ing. If the vehicle tires deterio-
rate, you could lose control of th e steering wheel or the brakes.

Installing the spare tire
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is
in motion, causing the tire to
come off.
Install the tire and loosely tighten
each wheel nut by hand by
approximately the same amount.
Tighten the wheel nuts until the
tapered portion comes into
loose contact with the disc
wheel seat.
Lower the vehicle.

■Jack point guide
■After completing the tire change
The tire pressure warning system must be reset. ( P. 674)
■When using the compact spare tire
As the compact spare tire is not equipped with a tire pressure warning
valve and transmitter, low inflation pressure of the spare tire will not be
indicated by the tire pressure warn ing system. Also, if you replace the
compact spare tire after the tire pressure warning light comes on, the
light remains on.
■If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on one of the rear wheels of the vehicle.
Perform the following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of
the vehicle.
Fit tire chains to the front tires.
The jack point guides are located on
the side of rocker moulding. They indi-
cate the jack point positions.

CAUTION
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may resu
lt 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 wh eel, 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. 689)
