●In the following situations the system may not be able to correctly detect the surround- ing brightness level. This may cause the low beams to remain on or the high beams to flash or dazzle pedestrians or vehicles ahead. In such a case, it is necessary to manually
switch between the high and low beams.
• When driving in inclement weather (heavy rain, snow, fog, sandstorms, etc.) • When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or damaged • When the camera sensor is deformed or dirty• When the temperature of the camera sensor is extremely high
• When the surrounding brightness level is equa l to that of headlights, tail lights or fog lights• When headlights or tail lights of vehicles ah ead are turned off, dirty, changing color,
or not aimed properly • When the vehicle is hit by water, snow, dust, etc. from a preceding vehicle• When driving through an area of interm ittently changing brightness and darkness
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved roads, gravel roads, etc.)• When frequently and repeatedly taking curves or driving on a winding road
• When there is a highly reflective object ahead of the vehicle, such as a sign or mirror • When the back of a preceding vehicle is highly reflective, such as a container on atruck
• When the vehicle's headlights are damaged or dirty, or are not aimed properly • When the vehicle is listing or titling due to a flat tire, a trailer being towed, etc. • When the headlights are changed between the high beams and low beams repeat-
edly in an abnormal manner • When the driver believes that the high beams may be flashing or dazzling pedestri-ans or other drivers
• When the vehicle is used in an area in which vehicles travel on the opposite side of the road of the country for which the vehicle was designed, for example using a vehi-
cle designed for right-hand traffic in a left-hand traffic area, or vice versa

Washer/wiper dual operation
The wipers will automatically operate a
couple of times after the washer squirts.
Vehicles with headlight cleaners: When the engine switch is in IGNI-
TION ON mode and the headlights are on, if the lever is pulled, the headlightcleaners will operate once. After this,
the headlight cleaners will operate every 5th time the lever is pulled.
■The windshield wipers and washer can be operated when
The engine switch is in IGNITION ON mode.
■Dripping prevention wiper sweep (vehicles with rain-sensing windshield wipers)
After washing and wiping operation severa l times, the wipers operate one more time after a short delay to prevent dripping. However, this function will not operate while driv- ing.
■Effects of vehicle speed on wiper operation
Vehicle speed affects the Intermittent wiper interval.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to the “AUTO” position while the engine switch is in IGNI-
TION ON mode, the wipers will operate on ce to show that AUTO mode is activated.
●When the sensor sensitivity ring is turned toward high while in “AUTO” position, the wipers will operate once to indicate th at the sensor sensitivity is enhanced.
●If the temperature of the raindrop sensor is 90C (194F) or higher, or -15C (5F) or lower, automatic operation may not occur. In this case, operate the wipers in any modeother than AUTO mode.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked, if there is washer fluid in the washer fluid tank.
■Washer nozzle heaters (if equipped)
The washer nozzle heaters operate when the outside temperature is 5°C (41°F) or less
and the engine switch is in IGNITION ON mode.

WARNING
■Before using LKA system
Do not rely solely upon the LKA system. LKA is not a system which automatically drives the vehicle or reduces the amount of attention that must be paid to the area in
front of the vehicle. The driver must always assume full responsibility for driving safely by always paying careful attention to the surrounding conditions and operate the steer-ing wheel to correct the path of the vehicle. Also, make sure to take adequate breaks
when fatigued, such as from driv ing for a long period of time. Failure to perform appropriate driving operat ions and pay careful attention may lead to an accident, resulting in death or serious injury.
■To avoid operating LKA by mistake
When not using the LKA system, use the LKA switch to turn the system off.
■Situations unsuitable for LKA
Do not use the LKA system in the following situations. The system may not operate properly and le ad 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 pressure is low.
●Tires which differ by structure, manufacturer, brand or tread pattern are used.
●Objects or patterns that could be mistaken for white (yellow) lines are present on the side of the road (guardrails, cu rbs, 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.
●Vehicle is driven in a temporary lane or restricted lane due to construction work.
●Vehicle is driven on a road surface which is slippery due to rainy weather, fallen snow, freezing, etc.
●Vehicle is driven in traffic lanes other than on highways and freeways.

Pulling the lever toward you cancels
the speed control.
The speed control is also canceled when
the brake pedal is depressed.
(When the vehicle has been stopped by system control, depressing the brake
pedal does not cancel the setting.)
Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.
However, when a vehicle ahead is not detected, cruise control does not resume when the vehicle speed is approximately 40 km/h (25 mph) or less.
When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the driver.
An example of this would be if another
driver cuts in front of you while you are
following a vehicle. Depress the brake
pedal to ensure an appropriate vehicle-
to-vehicle distance.
■Warnings may not occur when
In the following instances, warnings may not occur even when the vehicle-to-
vehicle distance is small.
●When the speed of the preceding vehicle matches or exceeds your vehicle
speed
●When the preceding vehicle is traveling at an extremely slow speed
●Immediately after the cruise control speed was set
●When depressing the accelerator pedal

Large adjustment: The set speed can be incr eased or decreased continually until the
lever is released.
*1: When the set speed is shown in “km/h”
*2: When the set speed is shown in “MPH”
Pulling the lever toward you cancels
the constant speed control.
The speed setting is also canceled when
the brake pedal is depressed.
Pushing the lever up resumes the
constant speed control.
However, resuming is available when the vehicle speed is more than approxi-
mately 40 km/h (25 mph).
