Forward collision warning and Autonomous
emergency braking system with Pedestrian
Detection
Conditions for operation
The Autonomous emergency braking system operates:- between 3 and 87 mph (5 and 140 km/h), in the case of a moving vehicle,- at a speed below 50 mph (80 km/h), in the case of a stationary vehicle,- at a speed below 36 mph (60 km/h), in the case of a pedestrian,- if the passenger seat belts are fastened,- if the vehicle is not accelerating sharply,- if the vehicle is not in a tight corner.
The Forward collision warning system allows the driver to be warned that their vehicle is at risk of collision with the vehicle in front or a pedestrian in their traffic lane.The Autonomous emergency braking system inter venes following the aler t if the driver does not react quickly enough and does not operate the vehicle's brakes.If the driver fails to act, it contributes towards avoiding a collision or limiting its severity by reducing the speed of your vehicle.
These systems use a radar located in the front bumper and a camera at the top of the windscreen.
These system are designed to improve road safety.It is the driver's responsibility to continuously monitor the state of the traffic, obser ving the driving regulations.These systems do not replace the need for vigilance on the part of the driver.
The Forward collision warning system only operates:- with a registered vehicle pointing in the same direction as the traffic, moving or stationary,- with pedestrians.- from 4 mph (7 km/h) (and is deactivated at 3 mph (5 km/h)).

The Autonomous emergency braking system does not operate:- if the front bumper is damaged,- if the system has been triggered in the last 10 seconds,- if the electronic stability control system has a fault.
Limits of operation
It is recommended that the system be deactivated in the vehicle configuration menu in the following cases:- if the windscreen has impact damage close to the detection camera,- when towing a trailer or caravan,- when a load on the roof rack extends beyond the windscreen (for example: long objects),- when the vehicle is being towed, with the engine running,- when a "space-saver" type spare wheel is fitted (if your vehicle has one),- when on a rolling road for a ser vice in a workshop,- when in an automatic car wash,- if the brake lamps are not working.
Following an impact, the system is automatically disabled; contact an authorized Toyota dealer or repairer, or another duly qualified and equipped professional to have the system checked.
Forward collision warning
Depending on the degree of risk of collision detected by the system and the alert threshold chosen, different levels of alert can be triggered and displayed in the instrument panel or the head-up display.
This level of alert is based on the inter-vehicle time between your vehicle and the vehicle ahead.
Level 1: visual alert only, warning you that the vehicle ahead is very close.A message on your vigilance is displayed as you close on the vehicle ahead.
This information also appears in the head-up display.For more information on the Head-up display, refer to the corresponding section.
Driving

241
This level of alert is based on the time before collision. It takes account of the vehicle dynamics, the speed of your vehicle and the one in front, the environmental conditions, the operation of the vehicle (cornering, pedals pressed, etc.) to trigger the alert at the best moment.
Level 2: visual and audible alert, warning you that a collision is imminent.A message indicating that you should brake is displayed.
Where the speed of your vehicle is too high approaching another vehicle, the first level of alert may not be displayed: the level 2 alert may be displayed di r e c t l y.Furthermore, the level 1 alert is never displayed with the "Close" threshold.Poor weather conditions (very heavy rain, accumulation of snow in front of the radar and the camera) may hinder the operation of the system, with the display of an operating fault message. The system remains out of ser vice until the message disappears.
Programming the alert thresholds
The thresholds for triggering an alert determine how you wish to be warned of the presence of a vehicle moving or stationary ahead of you, or a pedestrian in your traffic lane.You can select one of three thresholds:- "Distant", to be warned early (cautious driving).- "Normal".
- "Close", to be warned later.
With audio system or touch screen
The current threshold can be modified in the vehicle configuration menu using the audio system or the touch screen.

This system, also called automatic emergency braking, aims to reduce the speed of impact or avoid a frontal collision by your vehicle (between 3 and 87 mph (5 and 140 km/h) where the driver fails to react.Using a radar and a camera, this system acts on the vehicle's braking system.
Autonomous emergency
braking
The driver can take back control of the vehicle at any time by sharply turning the steering wheel and/or pressing the accelerator pedal.
Operation of the system may be felt by slight vibration in the brake pedal.If the vehicle comes to a complete stop, the automatic braking is maintained for 1 to 2 seconds.If your vehicle has a manual gearbox, in the event of the automatic emergency braking bringing the vehicle to a complete stop, the engine may stall.If your vehicle has an automatic gearbox, in the event of the automatic emergency braking bringing the vehicle to a complete stop, the vehicle will move off again; press the brake pedal.
If automatic emergency braking is not activated, you are alerted by the fixed display of this warning lamp accompanied by a message.
If the radar and the camera have confirmed the presence of a vehicle or a pedestrian, this warning lamp flashes when the system is operating.
Important: if operation of the automatic emergency braking is triggered, you should take back control of your vehicle and brake with the pedal to add to or finish the automatic braking.

Deactivation / Activation of
the alert and the braking
By default, the function is automatically activated at every engine start.
Autonomous emergency braking system with Pedestrian Detection
If the driver does not brake sufficiently to avoid an accident, this system will complete the braking.This emergency braking system will not act if you press the brake pedal.
In the event of a fault, you are alerted by the illumination of this warning lamp, accompanied by an audible signal and a message.Contact an authorized Toyota dealer or repairer, or another duly qualified and equipped professional.
Operating fault
There may be inter ference in the operation of the camera or it not work at all in the following situations:- poor visibility (inadequate street lighting, falling snow or rain, fog, ...),- dazzle (headlamps of an approaching vehicle on the other side of the road, low sun, reflection on a wet road, leaving a tunnel, alternating between light and shade, ...),- the area in front of the windscreen: dirty, misty, frosty, snow-covered, damaged or covered by a sticker.The operation of the radar, located in the front bumper, may be disturbed in certain weather conditions: with accumulations of snow, ice, mud, ...
With audio system or touch screen
This system can be deactivated or activated via the vehicle configuration menu.

Driver Attention Alert
The system resets itself if one of the following conditions is met:- engine running, the vehicle has been stationary for more than 15 minutes,- the ignition has been switched off for a few minutes,- the driver's seat belt is unfastened and their door is open.
As soon as the speed of the vehicle drops below 40 mph (65 km/h), the system goes into standby.The driving time is counted again once the speed is above 40 mph (65 km/h).
The system cannot in any circumstances replace the need for vigilance on the part of the driver.
Do not take the wheel if you are tired.
The system triggers an alert once it detects that the driver has not taken a break after two hours of driving at a speed above 40 mph (65 km/h).
It is recommended that you take a break as soon as you feel tired or at least every two hours.Depending on version, the vehicle either has the "Driving time warning system" only, or this combined with the "Driver Attention Alert".
Driving time warning
Activation / Deactivation
This alert takes the form of the display of a message encouraging you to take a break, accompanied by an audible signal.If the driver does not follow this advice, the alert is repeated hourly until the vehicle is stopped.
With audio system or touch screen
Activation or deactivation is done in the vehicle configuration menu.

Using a camera placed at the top of the windscreen, the system assesses the driver's level of vigilance by identifying variations in trajectory compared to the lane markings.This system is particularly suited to fast roads (speed higher than 40 mph (65 km/h)).
Driver Attention Alert
Depending on version, the "Driving time warning system" may be combined with the "Driver Attention Alert".
The system cannot, in any circumstances, replace the need for vigilance on the part of the driver.Do not drive if you are tired or taking medicines that can cause drowsiness.
Once the system considers that the behaviour of the vehicle suggests a certain level of fatigue or inattention by the driver, it triggers the first level of alert.
After three first level alerts, the system triggers a new alert with the message "Take a break!", accompanied by a more pronounced audible
signal.
In certain driving conditions (poor road sur face or strong winds), the system may give alerts independent of the driver's level of vigilance.
The following situations may interfere with operation of the system or prevent it working:- poor visibility (inadequate lighting of the roadway, falling snow, heavy rain, dense fog, ...),- dazzle (headlamps of an oncoming vehicle, low sun, reflections on a damp road, leaving a tunnel, alternating shade and light, ...),- windscreen area located in front of the camera: dirty, misted, frost-covered, snow-covered, damaged or covered by a sticker,- lane markings absent, worn, masked (snow, mud) or multiple
(roadworks, ...),- close to the vehicle ahead (lane markings not detected),- roads that are narrow, winding, ...
The driver is then alerted by the message "Ta k e c a r e !", accompanied by an audible signal.

Blind spot monitoring system
A warning lamp appears in the door mirror on the side in question:- immediately, when being overtaken,- after a delay of about one second, when overtaking a vehicle slowly.
This driving assistance system warns the driver of the presence of another vehicle in the blind spot angle of their vehicle (areas masked from the driver's field of vision), as soon as this presents a potential danger.
The alert is given by a warning lamp which comes on in the door mirror on the side in question as soon as a vehicle - car, lorry, bicycle - is detected and the following conditions are fulfilled:- all the vehicles must be moving in the same direction and on adjacent lanes,- the speed of your vehicle is between 7 and 87 mph (12 and 140 km/h),- when you overtake a vehicle with a speed difference of less than 6 mph (10 km/h),- when a vehicle overtakes you with a speed difference of less than 15 mph (25 km/h),- the traffic must be flowing normally,- in the case of an overtaking manoeuvre, if this is prolonged and the vehicle being overtaken returns to the blind spot,- you are driving on a straight or slightly curved road,- your vehicle is not pulling a trailer, a caravan...
This system is designed to improve safety when driving and is in no circumstances a substitute for the use of the interior rear view mirror and door mirrors. It is the driver's responsibility to constantly check the traffic, to assess the distances and relative speeds of other vehicles and to predict their movements before deciding whether to change lane.The blind spot sensor system does not replace the need for vigilance on the part of the driver.
