4-3. Operating the lights and wipers
Driving
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.
WARNING
■Caution regarding the use of windshield wipers in AUTO mode (vehicles with rain-sensing wind- 
shield wipers) 
The windshield wipers may operate  unexpectedly if the sensor is touched  
or the windshield is subject to vibra- tion in AUTO mode. Take care that your fingers or anything else do not  
become caught in the windshield wip- ers.
■Caution regarding the use of washer fluid 
When it is cold, do not use the washer  
fluid until the windshield becomes  warm. The fluid may freeze on the windshield and cause low visibility.  
This may lead to an accident, result- ing in death or serious injury.
NOTICE
■When there is no washer fluid  
spray from the nozzle 
Damage to the washer fluid pump  may be caused if the lever is pulled  
toward you and held continually.
■When a nozzle becomes blocked 
In this case, contact any authorized  Toyota retailer or Toyota authorized repairer, or any reliable repairer. 
Do not try to clear it with a pin or other  object. The nozzle will be damaged.

4-5. Using the driving support systems
WARNING
●In some situations, while the pre- collision braking function is operat- 
ing, operation of the function may  be canceled if the accelerator pedal is depressed strongly or the steer- 
ing wheel is turned and the system  determines that the driver is taking evasive action.
●If the brake pedal is being depressed, the system may deter- 
mine that the driver is taking eva- sive action and possibly delay the operation timing of the pre-collision  
braking function.
■Emergency steering assist (for 
region A)
●As emergency steering assist oper- ation will be canceled when the sys- 
tem determines that lane departure  prevention function has been com-pleted.
●Emergency steering assist may not operate or may be cancel in the fol- 
lowing cases as the system may  determine the driver is taking actions. 
• If the accelerator pedal is being  depressed strongly, the steering  
wheel is being operated sharply,  the brake pedal is being depressed or the turn signal lever is being  
operated. In this case, the system  may determine that the driver is tak-ing evasive action and the emer- 
gency steering assist may not  operate. 
• In some situations, while the emer- gency steering assist is operating, operation of the function may be  
canceled if the accelerator pedal is  depressed strongly, the steering wheel is operated sharply or the  
brake pedal is being depressed and  the system determines that the driver is taking evasive action.
• When the emergency steering assist is operating, if the steering wheel is held firmly or is operated in  
the opposite direction to that which  the system is generating torque, the function may be canceled.
■When to disable the pre-colli-sion system 
In the following situations, disable the  system, as it may not operate prop-erly, possibly leading to an accident  
resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing  another vehicle
●When transporting the vehicle via truck, boat, train or similar means of  
transportation
●When the vehicle is raised on a lift 
with the engine running and the  tires are allowed to rotate freely
●When inspecting the vehicle using a drum tester such as a chassis dynamometer or speedometer tes- 
ter, or when using an on vehicle  wheel balancer
●When a strong impact is applied to the front bumper or front grille, due to an accident or other reasons
●If the vehicle cannot be driven in a stable manner, such as when the  
vehicle has been in an accident or  is malfunctioning
●When the vehicle is driven in a sporty manner or off-road
●When the tires are not properly inflated
●When the tires are very worn
●When tires of a size other than  
specified are installed
●When tire chains are installed

■Situations in which the system may  
not operate properly
●In some situations such as the follow-
ing, an object may not be detected by  the radar sensor and front camera, preventing the system from operating  
properly: • When a detectable object is approaching your vehicle 
• When your vehicle or a detectable  object is wobbling• If a detectable object makes an abrupt  
maneuver (such as sudden swerving,  acceleration or deceleration)• When your vehicle approaches a  
detectable object rapidly • When a detectable object is not directly in front of your vehicle 
• When a detectable object is near a  wall, fence, guardrail, manhole cover,  
vehicle, steel plate on the road, etc. • When a detectable object is under a structure
