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.

request that a record of maintenance
be kept.
■Does your vehicle need repairs?
Be on the alert for changes in perfor-
mance and sounds, and visual tip-offs
that indicate service is needed. Some
important clues are:
●Engine misses (misfire), stumbling or
pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-
ever, water dripping from the air con-
ditioning system after use is normal.)
●Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
●Flat-looking tires, excessive tire
squeal when cornering, uneven tire
wear
●Vehicle pulls to one side when driven
straight on a level road
●Strange noises related to suspension
movement
●Loss of brake effectiveness, spongy
feeling brake pedal or clutch pedal
(vehicles with a manual transmission),
pedal almost touches the floor, vehicle
pulls to one side when braking
●Engine coolant temperature continu-
ally higher than normal (→P.83, 86)
If you notice any of these clues, take
your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer as soon as possi-
ble. Your vehicle may need adjustment
or repair.
