WARNING
If a warning light illuminates or 
flashes, or a warning message is dis-
played, immediately stop the vehicle 
in a safe place. Do not open the hood 
to inspect the engine, as doing so 
may lead to serious injury, such as 
steam burns. If a warning message is 
displayed, perform the necessary pro-
cedures according to the displayed 
message or explanation in the 
owner’s manual.
These warning messages indicate 
that a malfunction has occurred in a 
system or function of the vehicle. If 
you continue to drive the vehicle, the 
engine may stop suddenly, possibly 
leading to an accident. Also, even if 
no warning lights are illuminated or 
messages are displayed, if any 
abnormal sounds, smells or vibrations 
are detected, or of the engine stops 
suddenly, refrain from opening the 
hood to inspect the engine and con-
sult an authorized Toyota retailer or 
Toyota authorized repairer, or any reli-
able repairer.
WARNING
If you hear a loud noise or feel some-
thing impact the underside of the 
vehicle while driving, immediately 
stop the vehicle in a safe place.
After stopping the vehicle in a safe 
place, check the underside of the 
vehicle for any leaking brake fluid, oil 
or fuel. If any fluid is leaking, stop 
driving immediately and have the 
vehicle inspected by an authorized 
Toyota retailer or Toyota authorized 
repairer, or any reliable repairer.
Brake and fuel lines run under the 
floor of the vehicle. If any of these 
lines are damaged, the brakes may 
fail or leaking fuel may ignite and 
cause a fire.
WARNING
If the engine stalls while driving, sev-
eral warning lights will illuminate. 
Depending on vehicle specifications, 
the power-assisted brakes and power 
steering may stop operating. In this 
case the braking power will be 
reduced and operation of the steering 
wheel will become heavy. Although 
the operation of the brakes and steer-
ing will not be totally lost, they will 
require stronger than normal input to 
operate. Stop the vehicle in a safe 
place as soon as possible.
