5428-2. Steps to take in an emergency
■Rear passengers’ seat belt reminder lights*1 (warning buzzer)*2
*1: This light illuminates on the multi-information display.
*2: Rear passengers’ seat belt warning buzzer:
The rear passengers’ seat belt warning buzzer sounds to alert the rear passen-
ger that his or her seat belt is not fastened. If the seat belt is unfastened, the
buzzer sounds intermittently for a certain period of time after the vehicle reaches
a certain speed.
■Warning buzzer
In some cases, the buzzer may not be
heard because of noisy place or an audio sound.
■Front passenger detection sensor, seat belt reminder and warning
buzzer
●If luggage is placed on the front pas-
senger seat, the front passenger detection sensor may cause the warn-ing light to flash and the warning
buzzer to sound even if a passenger is not sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning light may not operate properly.
■If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes com-pletely empty. If the fuel tank is empty,
refuel the vehicle immediately. The mal- function indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer as soon as possible.
■Electric power steering system
warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tem-
porarily drops, the electric power steer- ing system warning light may come on and the warning buzzer may sound.
At this time, the functions of the air con- ditioning, etc. may be partially limited in order to reduce the power consumption
of the 12-volt battery.
■When the tire pressure warning light comes on
Inspect the tires to check if a tire is
punctured.
If a tire is punctured: P.548, 559
If none of the tires are punctured:
Turn the power switch to OFF then turn it to ON. Check if the tire pressure warn-ing 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.

8-2. Steps to take in an emergency
When trouble arises
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.492)
■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 com-pact spare tire (vehicles with com-
pact spare tire)
The compact spare tire is not equipped with a tire pressure warning valve and
transmitter. 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 standard 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.490
WARNING
■If a warning light comes on or a
warning buzzer sounds when a
warning message is shown on
the multi-information display*
Check and follow the message shown
on the multi-information display.
Failure to do so may result in death or serious injury.*: Warning lights illuminate in red or
yellow and the warning buzzer
beeps once or sounds continu-
ously.
■When the electric power steer- ing system warning light comes on
When the light comes on yellow, the assist to the power steering is restricted. When the light comes on
red, the assist to the power steering is lost and handling operations of the steering wheel 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 pre-
cautions. 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
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 authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
