turning the engine switch off.
Pull the lever toward you and release it again to turn off the lights.
●When the steering wheel or turn signal lever is operated while the headlights
are on (low beam), a cornering light will turn on and light up the direction of
movement of the vehicle. The cornering lights are designed to ensure excel-
lent visibility when making a turn at an intersection.
However, when vehicle speed is approximately 35 km/h (22 mph) or higher, the cor-
nering lights will not turn on.
●When the shift lever is in R while the headlights are on (low beam), both cor-
nering lights will turn on. This is designed to enhance visibility when parking.

■Conditions in which the light distribution control of the headlights changes automati-
cally
●When all of the following conditions are met, the high beams will be turned on automat- ically and the system will operate:
• The vehicle speed is approximately 60 km/h (38 mph) or more. • The area ahead of the vehicle is dark.
●When all of the following conditions are me t, the shaded high beams will turn on and the distance that the low beams are projecte d will be adjusted automatically, depending on the location of vehicles ahead:
• The vehicle speed is approximately 60 km/h (38 mph) or more. • The area ahead of the vehicle is dark.• There are vehicles ahead with headlights or tail lights turned on.
●If any of the following conditions is met, the high beams or shaded high beams will be changed to the low beams automatically:
• The vehicle speed is below approximately 60 km/h (38 mph). • The area ahead of the vehicle is not dark.• There are many vehicles ahead.
• Vehicles ahead are moving quickly and the high beams may blind the drivers of the other vehicles.
■Camera sensor detection information
●The high beams may not be automatically changed to the shaded high beams in the fol-lowing situations:
• When vehicles ahead suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle • When vehicles ahead are hidden from sight du e to repeated curves, road dividers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road • When vehicles ahead have no lights
●The high beams may be changed to the shad ed high beams if a vehicle ahead that is using fog lights without its head lights turned on is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs and other
reflective objects may cause the high beam s to change to the shaded high beams, cause the high beams not to change to the sh aded high beams, or change the area that is not illuminated.
●The following factors may affect the amount of time taken to turn the high beam on or off, or the speed by which the areas not illuminated change:
• The brightness of headlights, fog lig hts, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead • When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle • The condition of the road (gradient, curve, condition of the road surface etc.)• The number of passengers and amount of luggage
●The light distribution control of the headlights may change unexpectedly.

• When the vehicle is cut in front of by another vehicle • When vehicles ahead cannot be detected due to repeated curves, road dividers orroadside trees
• When vehicles ahead appear in a faraway lane on a wide road • When the lights of vehicles ahead are not on
●The high beams may be turned off if a vehicl e ahead that is using fog lights without its headlights turned on is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs and other
reflective objects may cause the high beams to change to the low beams, or the low beams to remain on.
●The following factors may affect the amount of time taken for the high beams to turn on
or off:
• The brightness of the headlights, fog lights, and tail lights of vehicles ahead • The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side • When a vehicle ahead is a two-wheeled vehicle• The condition of the road (gradient, curve, condition of the road surface, etc.)

WARNING
■Limitations of the pre-crash safety system
●The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
Do not use the pre-crash safety system instead of normal braking operations under any circumstances. This system will not pr event collisions or lessen collision damage or injury in every situation. Do not overly rely on this system. Failure to do so may lead
to an accident, resulting in death or serious injury.
●Although this system is designed to help avoid a collision or help reduce the impact of the collision, its effectiveness may change according to various conditions, therefore
the system may not always be able to achieve the same level of performance. Read the following conditions carefully. Do not overly rely on this system and always drive carefully.
• Conditions under which the system may oper ate even if there is no possibility of a collision: P. 307 • Conditions under which the system may not operate properly: P. 310
●Do not attempt to test the operation of the pre-crash safety system yourself, as the system may not operate properly, possibly leading to an accident.
■Pre-crash braking*3
●When the pre-crash braking function is operating, a large amount of braking forcewill be applied.
●If the vehicle is stopped by the operation of the pre-crash braking function, the pre- crash braking function operation will be canceled after approximately 2 seconds. Depress the brake pedal as necessary.
●The pre-crash braking function may not operate if certain operations are performedby the driver. If the accelerator pedal is being depressed strongly or the steering wheel is being turned, the system may determine that the driver is taking evasive
action and possibly prevent the pre-crash braking function from operating.
●In some situations, while the pre-crash brakin g function is operating, 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 determine that the driver is tak- ing evasive action and possibly delay the operation timing of the pre-crash braking
function.
*3: Depending on the region in which the vehicle was sold, the pre-crash braking func-
tion may not be available.

WARNING
■When to disable the pre-crash safety system
In the following situations, disable the syst em, as it may not operate properly, 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 th e 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 tester, or when using an on vehicle wheel balancer
●When a strong impact is applied to the fron t 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 beenin 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
●When a compact spare tire or an emergency tire puncture repair kit is used
●If equipment (snow plow, etc.) that may obstruct the radar sensor or camera sensor is
temporarily installed to the vehicle

■Pedestrian detection function*4
*4: Depending on the region in which the vehicle was sold, the pedestrian detection func-
tion may not be available.
■Cancelation of the pre-crash braking*3
If either of the following occur while the pre- crash braking function is operating, it will be canceled:
●The accelerator pedal is depressed strongly.
●The steering wheel is turned sharply or abruptly.
*3: Depending on the region in which the vehi cle was sold, the pre-crash braking function
may not be available.
■Conditions under which the system may operate even if there is no possibility of a colli-
sion
●In some situations such as the following, the system may determine that there is a possi- bility of a frontal collision and operate.
• When passing a vehicle or pedestrian*4
• When changing lanes while overtaking a preceding vehicle • When overtaking a preceding vehicle that is changing lanes
The pre-crash safety system detects pedestrians
based on the size, profile, and motion of a detected object. However, a pedestrian may notbe detected depending on the surrounding
brightness and the motion, posture, and angle of the detected object, preventing the system fromoperating properly. ( P. 312)
• When overtaking a preceding vehicle that is making a left/right turn
• When passing a vehicle in an oncoming lane that is stopped to make a right/left turn

• After the engine has started the vehicle has not been driven for a certain amount of time• While making a left/right turn and for a few seconds after making a left/right turn
• While driving on a curve and for a few seconds after driving on a curve • If your vehicle is skidding
• If the wheels are misaligned • If a wiper blade is blocking the camera sensor
• The vehicle is wobbling. • The vehicle is being driven at extremely high speeds.• When driving on a hill
• If the radar sensor or camera sensor is misaligned
●In some situations such as the following, sufficient braking force may not be obtained,
preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively worn, improper tire inflation pressure, etc.)• When the vehicle is being driven on a gravel road or other slippery surface
• If the front of the vehicle is raised or low- ered
