Glossary

ABS (Anti-Skid Braking System)

Modern electronics and a hydraulic actuator compares and adjusts wheel speeds when braking to prevent wheel lock-up and hence a potential skid. (Toyota ABS includes a sophisticated gravel road strategy, which in the special circumstance of braking on a gravel road ensures the tyres brake through the loose gravel to maximise stopping power.)


Active All-Wheel Drive (Active AWD)

System developed to provide enhanced control and improved fuel economy. Toyota Active AWD is a compact system that controls torque distribution between the front and rear axles – using a newly developed electromagnetic coupling in the rear differential housing. Electronically controlled Active AWD system saves engine power and fuel by only driving the front wheels. It switches automatically to all-wheel drive when needed, for example if a loss of front-wheel traction is anticipated.

Active Height Control (AHC)

Allows the driver to vary the ride height to suit off-road driving (increased height) and ease of entry (decreased height).

Active Traction Control (ATRC)

This system dynamically distributes the torque to each wheel as well as regulates brake pressure, eliminating wheel-spin and ensuring that the tyres with the best grip always help the driver to keep the vehicle in motion. The system automatically adjusts to the transfer range selected no matter what sort of driving conditions you tackle.

Advanced Variable Gear Ratio Steering (VGRS)

Electrically powered system to provide increased steering assistance and a quicker steering gear ratio at low speeds, as well as optimum driving feel. A boon when parking, its benefits also include reducing understeer and enhanced steering adjustment when cornering, and reducing the steering wheel angle required to make a lane change.

Anti-intrusion beams

Beams placed in the side doors to protect the occupants in the event of a side impact to the vehicle.

Artificial Intelligence Shift Control (AI Shift Control)

One of the modern ECT features, it provides the ability to “read” the driver’s intentions and to “read” hills, AI Shift Control is a transmission algorithm designed to manage the shift regime according to road conditions and driver behaviour. It uses data on accelerator pedal angle and rate of change, throttle angle and engine speed.

Bluetooth?

A short-range wireless communication system ideally suited to hands-free use of mobile telephones in cars*. Can be linked to steering-wheel mounted controls and the vehicle’s touch screen to provide access to your phone directory, call register, received calls, number editing and fast dials.

* Bluetooth™ will only operate with telephones enabled with compatible Bluetooth™ wireless technology (HFP (Hands Free Profile) v1.0 and OPP (Object Push Profile) v1.1 international standards).


Brake Assist (BA)

A system designed to assist the driver in emergency braking, where the driver cannot apply the high pedal force required to obtain the shortest possible braking distance. It supplements the braking power applied if the driver has not pushed hard enough on the brake pedal in an emergency braking situation – working in conjunction with ABS.

Downhill Assist Control (DAC)

Electronically controlled system designed to help prevent the vehicle slipping sideways during steep off-road hill descents. It provides “feet off” driving down a steep incline.


Driver Assist Technology (DAT)

DAT encapsulates Toyota’s latest advances in 4WD technology – to in effect do the thinking for you. This technology is designed to suit on and off-road applications. The DAT features can include Active 4WD, Downhill Assist Control, Hill-start Assist Control, Toyota Electronically Modulated Suspension (TEMS), electronically controlled rear air suspension Active Traction Control (A-TRC), Vehicle Stability Control, Torsen limited slip centre differential with locking function, ABS anti-skid brakes with Electronic Brake-force Distribution and Brake Assist.

Dual-stage SRS airbags

Toyota’s dual-stage SRS (Supplemental Restraint System) front airbag system can deploy the driver and front passenger airbags at different rates according to the intensity of a frontal collision and the proximity of the seat occupant to the steering wheel/dashboard. The airbag SRS electronic control unit uses information from seat slide position sensors and impact sensors to determine the inflation rate and pressure of the airbags.

Electric Power-assisted Steering (EPS)

System in which an electric motor attached to the steering rack or shaft provides power assistance – in place of the conventional hydraulic assist system. The electric motor only consumes energy when power assistance is required (i.e. when the steering wheel is turned), thereby saving energy and fuel. The more straight-road driving, the greater the fuel saving. EPS eliminates the need for a hydraulic pump, hydraulic pipes, pulleys and belt, and power-steering fluid in the steering system. It therefore offers reduced service costs and environmental benefits, as well as saving fuel.

Electro-Multi-Vision (EMV)

State-of-the-art touch-screen display technology for the vehicle’s sound system, air conditioning system, vehicle information, satellite navigation, DVD (if fitted) and Bluetooth™ mobile telephone technology. Toyota uses Liquid Crystal Display (LCD) screen technology and high-quality Video Graphics Array (VGA) vision.

Electronic Brake-force Distribution (EBD)

A sophisticated electronic system designed to minimise stopping distances by maximising braking power to the wheels with the most grip. It replaces the conventional load sensing proportioning valve. The latest Toyota EBD can adjust the fore/aft brake balance according to vehicle load and the right/left brake balance if the brakes are applied during cornering.

Electronically Controlled Transmission (ECT)

Electronic control of the automatic transmissions has created a raft of breakthroughs in driving comfort and vehicle efficiency. ECT helps to ensures optimal gear change timing according to throttle position with vehicle load and judges the most suitable time to initiate torque converter lock-up for increased fuel economy, and networks with the engine’s computer.

Energy Absorbing Steering Column

Toyota steering columns have special sections that can compress, to absorb impact energy in a frontal collision. Current Toyota designs include features to absorb the energy of a secondary impact.
