460 5-2. Steps to take in an emergency
BRZ_U
■The compact spare tire (vehicles with a 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 only in an emergency.
●Make sure to check the tire pressure of the compact spare tire.
(→ P. 498)
■When using the compact spare tire (vehicles with a tire pressure
monitoring system)
As the compact spare tire is not equipped with the tire pressure warning
valve and transmitter, low inflation pressure of the spare tire will not be
warned. 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 rear tire (vehicles with a compact spare tire)
Install the compact spare tire on the front of the vehicle. Perform the fol-
lowing steps.
Replace a front tire with the compact spare tire.
Replace the flat rear tire with the tire removed from the front of
the vehicle.
■After completing the tire change (vehicles with a tire pressure mon-
itoring system)
The tire pressure monitoring system must be reset. ( →P. 371)

WARNING
■
Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery.
● Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended termi-
nal.
● Do not allow the jumper cables to come into contact with the “+” and “-” ter-
minals.
● Do not allow open flame or use matches, cigarette lighters or smoke near
the battery.
■ Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery.
● When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, clothing
or the vehicle body.
● Do not lean over the battery.
● In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
● Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
● Do not allow children near the battery.
■ To prevent damage to the vehicle
Do not pull- or push-start the vehicle as the three-way catalytic converter
may overheat and become a fire hazard.
