All Toyota 4runners came with Toyota's Star Safety System which includes anti-lock brakes, electronic brakeforce distribution, brake assist, traction control and Vehicle Stability Control. Side torso airbags for the front rows as well as side curtain airbags for the front and rear rows were optional on 2005-2007 models and became standard on 2008 models.
The Hilux Surf version for the Japanese market was also available with a range of diesel engines, including a 2.4 L turbodiesel 2L-TE I4 up to 1993, followed by a 3.0 L turbodiesel 1KZ-TE I4. A small number were also made with a normally aspirated 2.8 L diesel 3L I4. A small number were also produced with a 2.0 L 3Y I4 naturally-aspirated gasoline engine. A common modification for normally aspirated diesel engines (e.g. 2.8L) is the retro-fiting of a turbo (with or without intercooler kit), which can significantly improve performance.
