The first model in the Toyota range to add the system, the LandCruiser 200's sway control works with the existing stability technologies to help drivers if a trailer starts to swing from side to side.
The system works to combat crosswinds, bumpy roads and sharp turns, detecting trailer sway through information from the vehicle's yaw-rate, acceleration and steering sensors.
The sway control system will then use deceleration and yaw-moment controls to suppress the effects, alerting the driver via the slip indicator light in the dash and lighting up the rear lamps for following drivers.
The addition of this system follows recent upgrades to GX and GXL models, adding driver and front passenger knee airbags.
Other upgrades include tinted windows for the rear side, rear quarter and rear windscreen glass on GXL models.
The VX model gains automatic headlights and the Sahara adds both auto headlights and digital (DAB) radio.
The upgrades don't come for free however, with prices increasing across the range by $1500, starting with the five-seat turbo-diesel GX at $78,990.
The eight-seat turbo-diesel GXL is $89,990 plus the unchanged $3,250 option of the Kinetic Dynamic Suspension System. Seven-seat turbo-diesel VX is $100,990 and seven-seat turbo-diesel Sahara is $119,990.
The three eight-seat petrol models are GXL $84,990, VX $95,990 and Sahara $114,990.
LandCruiser 200 models are covered by Toyota Service Advantage capped-price servicing at $210 per service (maximum payable during 3yr/60,000km program).
Note: prices exclude on-road costs.
