With the launch of the all-new Toyota Hiace Super Grandia, it also signaled the arrival of Toyota Safety Sense. With that, the luxury van is also the first model offered here to come with this feature. But what exactly is Toyota Safety Sense or TSS?

So while it's safe to say (pun not intended) that the Super Grandia will be safe in the event of an accident. After all, the Hiace recently got top marks in the latest batch of ANCAP (Australasian New Car Assessment Program) testing. That means the van has good passive safety. As for Toyota Safety Sense, it can actually help prevent the accident from happening in the first place.

In the case of Toyota Safety Sense, it is called active safety. Also called TSS, it is a package that includes more of these features, on top of other active safety systems such as anti-lock brakes, traction control, and stability control. What's included in TSS? Here are four.

First up is the Pre-collision System (PCS). Also known as automatic emergency braking (AEB), it warns the driver of an impending impact through a series of beeps and flashes. If the driver does not respond to the warnings, PCS will do the braking instead. It will do that even if the brakes have not been applied by the driver.

Another clever piece of tech TSS has to offer is adaptive cruise control. Whereas standard cruise control stays at a constant speed, adaptive cruise control constantly adjusts the vehicle's pace depending on the conditions. When no cars are detected in front of the vehicle (in this case, the Hiace Super Grandia), it will maintain the speed set by the driver. The moment another car pulls in front of the vehicle, adaptive cruise control will cut down its speed and maintain a safe distance from the car in front. If the car in front stops, it will work in conjunction with the Pre-collision system to bring the Super Grandia to a halt.

Up next is Lane Departure Alert (LDA) which notifies the driver that they are straying out of their lane. This aims to keep the driver aware of their position on the road, and can also help prevent the driver from straying off of the road.

Last but not least is Automatic High Beam (AHB). The Super Grandia's LED headlights will, again, constantly adjust to the conditions if needed. AHB switches to low-beam if it detects oncoming traffic in order to prevent glaring or blinding the driver in the opposite lane. It then reverts back to high beam once the over vehicle has passed.

All in all, Toyota Safety Sense boosts the active safety equipment in the Super Grandia. These are standard on the top-spec model, the Elite. While all these can help prevent an accident, it's the driver that's still in control of the vehicle. What TSS does is make driving that little bit safer which, at the end of the day, just makes things a whole lot better for the rest of us.
