7-2. Steps to take in an emergency
When trouble arises
■Electric power steering system
warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering sys- tem warning light may come on and the warning buzzer may sound.
■When the tire pressure warning
light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: P.415, 426
If none of the tires are punctured: Turn the engine switch off then turn it to
ON. Check if the tire pressure warning light comes on or blinks.
If the tire pressure warning light blinks
for approximately 1 minute then stays on
There may be a malfunction in the tire
pressure warning system. Have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immedi- ately.
If the tire pressure warning light
comes on
1 After the temperature of the tires has lowered sufficiently, check the infla-tion pressure of each tire and adjust
them to the specified level.
2 If the warning light does not turn off even after several minutes have elapsed, check that the inflation
pressure of each tire is at the speci- fied level and perform initialization. ( P.367)
■The tire pressure warning light may
come on due to natural causes
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pres- sure changes caused by temperature. In this case, adjusting the tire inflation
pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare
tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and trans- mitter. If a tire goes flat, the tire pressure warning light will not turn off even
though the flat tire has been replaced with the spare tire. Replace the spare tire with the repaired tire and adjust the
tire inflation pressure. The tire pressure warning light will go off after a few min-utes.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure warning valve and transmitter.
The tire pressure warning light will turn on if the tire inflation pressure of the spare tire is low. If a tire goes flat, the
tire pressure warning light will not turn off even though the flat tire has been replaced with the spare tire. Replace the
spare tire with the repaired tire and adjust the tire inflation pressure. The tire pressure warning light will go off after a
few minutes.
■Conditions that the tire pressure warning system may not function properly
 P. 3 6 6
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any autho-rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer. The vehicle will become extremely unstable during braking, and the ABS
system may fail, which could cause an accident resulting in death or seri-ous injury.

When trouble arises
entry & start system when the battery
is discharged. Use the wireless remote control or the mechanical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has
recharged but will start normally after the second attempt. This is not a mal-function.
●The engine switch mode is memo-rized by the vehicle. When the battery
is reconnected, the system will return to the mode it was in before the bat-tery was discharged. Before discon-
necting the battery, turn the engine switch off.If you are unsure what mode the
engine switch was in before the bat- tery discharged, be especially careful when reconnecting the battery.
●The Stop & Start system may not automatically stop the engine for up to
an hour.
■When replacing the battery
●Use a battery that conforms to Euro-
pean regulations.
●Use a battery that the case size is
same as the previous one, 20 hour rate capacity (20HR) is equivalent or greater, and performance rating
(CCA) is equivalent or greater. Check the label on top of the battery for the battery size and specifications (ex.
LN2, 60Ah, 345A). • If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi-cle is not used is a short time, the bat-
tery may discharge and the engine may not be able to start.
●For details, consult any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
■When removing the battery ter-minals
Always remove the negative (-) termi- nal first. If the positive (+) terminal contacts any metal in the surrounding
area when the positive (+) terminal is removed, a spark may occur, leading to a fire in addition to electrical shocks
and death or serious injury.
■Avoiding battery fires or explo-
sions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery:
●Make sure each jumper cable is connected to the correct terminal and that it is not unintentionally in
contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to come into contact with
any other parts or metal surfaces in the area, such as brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into con-
tact with each other.
●Do not smoke, use matches, ciga-
rette lighters or allow open flame near the battery.
■Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following precautions when handling the bat-
tery:
