Ironically if you want a family vehicle for remote-area touring, the safest 70 Series carries only two passengers. That is the 79 Single-Cab ute, a fixture on mining fleets and the only 70 Series model to receive a five-star rating from safety authority ANCAP.
Safety in all 70 Series vehicles was improved with the upgrade of November 2016. But the 79 Single-Cab was improved more than others.
The main safety enhancement applied to all models was the addition of electronic stability control, which since 2014 has been mandatory on new passenger cars (but not on commercial vehicles). It can help you avoid losing control of a skidding vehicle (by controlling the brake on each wheel independently).
A related addition is electronic brake-force distribution, which makes sure each tyre is using all available grip when you want to stop in a hurry. This too has long been ubiquitous on passenger cars.
Also a safety improvement, especially in steep off-road driving, is the addition of Hill start assist, which helps you take off on uphill slopes (by controlling the brakes automatically). Toyota says it will work even when you are carrying a big load or towing a trailer.
All 70 Series models have two airbags up front, protecting the heads of the driver and front passenger in a frontal crash. (Only the 79 Single-Cab has other airbags.) All have seatbelt reminders on the front seats.
The 79 Single-Cab has, in addition, a frontal airbag for the driver at knee level, and curtain airbags on each side at head height that help in side-crashes, for a total of five.
The Single-Cab also has new seats that protect you better from whiplash injuries if you are struck from behind, and a revised chassis and steering mechanism that make it more likely you will walk away from a crash.
A reversing camera is not available even as an option on any 70 Series model.
The Australasian New Car Assessment Program (ANCAP) awarded the 79 Single-Cab five stars for safety, its maximum, in October 2016. The 79 Dual-Cab and other 70 Series models have not been rated.
