Second generation Toyota Safety Sense rolled out from 2018

For advanced vehicle safety systems to realise their best potential to reduce the number of traffic accidents and fatalities, they need to be operating on large numbers of vehicles. That’s why in 2015 Toyota decided to launch the democratisation of these technologies in its cars with Toyota Safety Sense, a set of active safety features designed to help prevent or mitigate the consequences of collisions across a wide range of traffic situations.

By making Toyota Safety Sense a standard feature or an affordable option on large numbers of its cars, Toyota helps larger numbers of motorists – and other road users – to benefit from the safeguards it can provide.

The package includes a Pre-Collision System (PCS), Lane Departure Alert (LDA), Road Sign Assist (RSA) and Automatic High Beam (AHB). Vehicles equipped with a millimetre-wave radar further benefit from Adaptive Cruise control and PCS with a pedestrian detection function.

More than five million Toyotas worldwide are now using Toyota Safety Sense; in Europe, 92 per cent of new cars are fitted with the technology. Studies in Japan reveal that in real-world traffic conditions there has been an approximate 50 per cent reduction in rear-end collisions – and a decrease of around 90 per cent where Toyota Safety Sense operates in combination with an Intelligent Clearance Sonar (ICS).


Toyota is committed to achieving a safe mobility society and believes it is important to take an approach that involves people, vehicles and the traffic environment, as well as pursuing real-world safety by learning from accidents and incorporating that knowledge in its vehicle development.

True to the company’s Kaizen philosophy of continuous improvement, Toyota is introducing the second generation Toyota Safety Sense. This comes with an improved system unit, an upgraded PCS function and new Lane Tracing Assist (LTA), while retaining the established ACC, RSA and AHB functions.


Vehicles will use a single-lens camera and millimetre – wave radar with higher performance, increasing the scope of hazard detection and improving functionality. The hardware is also more compact and easier to install.

Between speeds of approximately 6 and 112mph, the upgraded Pre-Collision System will detect vehicles ahead and reduce the risk of hitting them from the back. The system can also detect potential collisions with pedestrians (in day and night-time driving) and cyclists (during daylight hours), with automated braking operating at relative speeds between 6 and 50mph.

The new Lane Tracing Assist keeps the vehicle centred in its highway lane by helping the driver with steering control, when the Adaptive Cruise Control is operating. LTA also comes with an upgraded Lane Departure Alert which can recognise the margins of straight roads, even when white line markings are not used. Should the vehicle deviate from its lane, the system will sound a warning and provided assistance for the driver to steer the car back to its correct course.


The second generation Toyota Safety Sense will be progressively rolled out from the start of 2018, predominantly in Japan, Europe and North America.

    1. Hi there,

      Thanks for getting in touch. Unfortunately, we can’t comment on other markets and would recommend getting in touch with Toyota in your region for further help with this.


  1. Hello what Toyota cars come with tss2 in the uk at the moment? And from what year?

    Especially Prius and chr. Thanks

    1. Hi David,

      Currently, none of our UK vehicles have Toyota Safety Sense 2, but rather the first generation of Toyota Safety Sense. Toyota Safety Sense is provided as standard on all versions of both the current C-HR and Prius. Please keep an eye on our blog and social channels for future updates.


    1. Hi Brian,
      Thanks for getting in touch. Unfortunately, the Toyota Safety Sense system cannot be retrofitted.

  2. The press release states 2nd generation TSS will be “available on new models being launched as from 2018”. Am I correct in understanding this means it will only be fitted to brand new models launched as of this year and not to existing models manufactured this year?

    John Broughton asks if the 2nd gen TSS can be retrofitted but I don’t see an answer. I did consider buying a brand new Aygo when I first saw details of the 2nd gen TSS. Now I realise that, as the Aygo is not a new model, it is unlikely it will have the 2nd gen TSS fitted – but I would still be interested in the Aygo if it could be retro-fitted. Please advise.

    1. Hi David,
      Thanks for getting in touch.
      You are correct in your understanding. This does indicate brand new models that are launched from production, so not existing models such as Aygo. Currently, it will not be possible to retrofit this system either.
      We have passed your feedback on to our Product team.

      1. I am expecting delivery of a new Aygo auto in October will it have tss2 please it has yet to come off production line.

        1. Hi Paul,

          Thanks for getting in touch. Brand new models that are launched from production will have TSS2, not existing models such as Aygo.

          Hope this helps.

      2. Hi, just bought an yaris icon tech from Huddersfield RRG. Will be ready for Thursday. Can’t wait. Will the car come with the lane departure where it has steering assist?

        1. Hi Sufyan,

          Thanks for getting in touch, it’s great to hear that you’ll be driving a new Yaris Icon Tech!

          Yes, the car comes with Toyota Safety Sense which includes Lane Departure Alert.


  3. I really like this new system and if it will be implement on the Auris this year, I would then change my mind from a C-HR and get an Auris.

    1. Hi Daniel,
      Thanks for getting in touch. We can confirm that at the moment the system will only be available for the Auris. However, keep an eye on the blog for further updates. Many thanks.

    1. Hi Gethin. Thanks for your comment. We recommend keeping in touch with your local dealer for further details on this. Thanks.

  4. Hello, I am planning to purchase a Hybrid C-HR mid next year. Will this upgraded system be fitted on this model and if so, when (for UK models)?

    1. Hi Daniel,
      Thanks for your comment. Unfortunately, the new Toyota Safety Sense wont be in the MY18 C-HR. Many thanks.

    1. Hi John,
      Thanks for getting in touch. Please could you provide your reg and VIN number so we can look further in to this for you. Many thanks.
