The compact spare tire

●

The compact spare tire is identified by the label “TEMPORARY USE
ONLY” on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.

●

Make sure to check the tire inflation pressure of the compact spare
tire. (

P. 439)

■

After completing the tire change (U.S.A. only)

The tire pressure warning system must be reset. (

P. 315)

■

When using the compact spare tire (U.S.A. only)

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 warning 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.

CAUTION

■

Using the tire jack

Improper use of the tire jack may cause the vehicle to suddenly fall off
the jack, leading to death or serious injury.

●

Do not use the tire jack for any purpose other than replacing tires or
installing and removing tire chains.

●

Only use the tire jack that comes with this vehicle for replacing a flat
tire.
Do not use it on other vehicles, and do not use other tire jacks for
replacing tires on this vehicle.

●

Always check that the tire jack is securely set to the jack point.

●

Do not put any part of your body under the vehicle while it is supported
by the jack.

●

Do not start or run the engine while your vehicle is supported by the

CAUTION

■

Replacing a flat tire

Observe the following precautions to reduce the risk of death or serious
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 Scion dealer.

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

with the tapered end facing inward. (

P. 330)

■

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 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 seri-
ous injury.
