The two linked systems have been specifically engineered for the 1.5-litre engine in the Australian market, providing an electronic safety net for the more affordable models in Toyota's line-up.
These features are included along with the recently introduced MP3 and iPod compatibility and Bluetooth hands-free capability with audio streaming, also standard across the range.
"The addition of vehicle stability and traction control to the Yaris models fitted with the 1.5-litre engine can potentially reduce the number and severity of impacts. We will continue to add a variety of safety features to models across our range as the opportunity arises." Toyota Australia senior executive director sales and marketing David Buttner said.
Fuel consumption for the 1.5-litre manual models is 6.1-litre per 100km with emissions of just 145 grams of Co2 per kilometre.
In line with the additional standard equipment, pricing for the 1.5-litre models has increased from between $300 and $650 depending on specification.
