4-3. Operating the lights and wipers
Driving
1 Off
2 Rain-sensing operation
3 Low speed operation
4 High speed operation
5 Temporary operation
When AUTO is selected, the sensor
sensitivity can be adjusted by turning
the switch ring.
6 Increases the sensitivity
7 Decreases the sensitivity
8 Washer/wiper dual operation
The wipers will automatically operate a
couple of times after the washer squirts.
(After operating several times, the wipers
operate once more time after a short delay
to prevent dripping. However, the dripping
prevention does not operate while the
vehicle is moving.)
When the engine switch is
in IGNITION ON mode and
the headlights are on, if the lever is pulled,
the headlight cleaners will operate once.
After this, the headlight cleaners will oper-
ate every 5th time the lever is pulled.
■The windshield wiper and washer can be
operated when
The engine switch

is in
IGNITION ON mode .
■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 windshield.
●If the wiper is turned to AUTO position while the engine switch is
in IGNITION ON mode , the wipers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor is 85°C (185°F) or higher, or -30°C (-
22°F) or lower, automatic operation may not occur. In this case, operate the wipers in any mode other than AUTO.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.

drive the vehicle or reduce the amount of attention that must be paid to the area in front of the vehicle. The driver must
always assume full responsibility for driv- ing safely by paying careful attention to the surrounding conditions and operat-
ing the steering wheel to correct the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as
from driving for a long period of time. Failure to perform appropriate driving operations and pay careful attention may
lead to an accident, resulting in death or serious injury.
■To avoid operating LKA system by mistake
When not using the LKA system, use the LKA switch to turn the system off.
■Situations unsuitable for LKA system
Do not use the LKA system in the follow- ing situations.The system may not operate properly
and lead to an accident, resulting in death or serious injury.
●A spare tire, tire chains, etc. are equipped.
●When the tires have been excessively
worn, or when the tire inflation pres- sure is low.
●Tires which differ by structure, manu-facturer, brand or tread pattern are
used.
●Objects or patterns that could be mis- taken for white (yellow) lines are pres-ent on the side of the road (guardrails,
curbs, reflective poles, etc.).
●Vehicle is driven on a snow-covered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Asphalt repair marks, white (yellow) line marks, etc. are present due to road repair.
