On- or off-road, KDSS is the best of all worlds. Plus, it’s kinda fun to say. A standard feature in the Toyota Land Cruiser and optional in the Toyota 4Runner Trail Edition, KDSS features hydraulically linked front and rear stabilizer bars that remain firmly engaged while the vehicle is cornering on-road, helping to limit body roll. But when negotiating rough roads and rugged terrain, the stabilizer bars can be disengaged via KDSS for a much wider range of suspension movement.

This might just be an engine’s best friend. It detects high-frequency vibrations that are a precursor to pre-ignition (“pinging”), a condition that is potentially harmful to the engine. KCS can retard the ignition timing until the knock ceases, which allows an engine to take advantage of a high compression ratio (for more power) while reducing the risk of pre-ignition damage.
