4-3. Operating the lights and wipers
Driving
4 Temporary operation
When “AUTO” is selected, the wipers  
will operate automatically when the 
sensor detects falling rain. The system 
automatically adjusts wiper timing in 
accordance with rain volume and vehi-
cle speed.
When “AUTO” is selected, the sen- 
sor sensitivity can be adjusted as  
follows by turning the switch ring. 
5 Increases the rain-sensing wind- 
shield wiper sensitivity 
6 Decreases the rain-sensing  
windshield wiper sensitivity 
7  Washer/wiper dual oper- 
ation
Pulling the lever operates the wipers  
and washer. 
Wipers will automatically operate a cou- 
ple of times after the washer squirts.
■The windshield wiper and washer  can be operated when 
The engine switch is in ON.
■Effects of vehicle speed on wiper  operation 
Vehicle speed affects the Intermittent  
wiper interval.
■Raindrop sensor
●The raindrop sensor judges the 
amount of raindrops. An optical sensor is adopted. It may not operate properly when sunlight  
from the rising or setting of the sun  intermittently strikes the windshield, or if bugs etc. are present on the wind- 
shield.
●If the wiper is turned to AUTO mode 
while the engine switch is in ON, the  wipers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sen-sor is 85°C (185°F) or higher, or -15°C  
(5°F) or lower, automatic operation  may not occur. In this case, operate  
the wipers in any mode other than  AUTO mode.
■If no windshield washer fluid sprays 
Check that the washer nozzles are not  blocked if there is washer fluid in the windshield washer fluid reservoir.

7-2. Steps to take in an emergency 
ble.
■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. 3 2 5 
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.282)
■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).
■Conditions that the tire pressure  
warning system may not function  properly 
→ P. 2 8 0
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 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. When steering wheel operations are heavier than usual, grip the steering  
wheel firmly and operate it 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.
●Avoid abrupt maneuvering and braking.If the vehicle tires deteriorate, you  
could lose control of the steering  wheel or the brakes.
