Active Cruise Control (ACC):
For more relaxed highway cruising, Active Cruise Control (ACC)* monitors the road to maintain a set distance from the vehicle ahead. The radar sensor in the Sports Luxury grade front grille works as part of the Active Cruise Control (ACC). You can simply set your preferred highway speed via touch controls near the steering wheel, or additionally you can vary your desired following distance from the vehicle in front. Then, should the radar detect that distance is closing or detect another vehicle in your path, Active Cruise Control reduces your speed and even applies the brakes if necessary. Your nominated speed is resumed once a safe following distance can be maintained.

*ACC is a driver assist technology and should not be used in place of safe driving practices. Driver should continue to monitor road ahead.
Adaptive Front-lighting System (AFS):
The projector-type High Intensity Density (HID) low beams are directed around corners, to better illuminate your intended driving line. The inbuilt Adaptive Front-lighting System (AFS) responds to inputs from the steering angle sensor and the front wheel speed sensors, and activates at speeds above 10km/h.  The headlamps are able to swivel, so that the right and left headlamp have a range of movement.  The AFS helps ensure improved illumination for greater safety at night.
Atkinson Cycle:
The Atkinson, or high-expansion, Cycle can have a higher compression ratio than a conventional Otto Cycle engine. The design makes full use of combustion energy by keeping the exhaust valves closed until the end of the expansion stroke. The expansion stroke is extended, converting more of the combustion energy into torque on the crankshaft, resulting in improved efficiency.
Crawl Control:
You can think of Crawl Control as off-road cruise control for uphill and downhill driving. It is an advanced technology that allows you to concentrate on steering the vehicle in difficult terrain. When driving along rocky or otherwise challenging off road trails, Crawl Control maintains a slow, steady rate of progress. Simply select your preferred speed using the switch near the shift lever and Crawl Control maintains that pace. Crawl Control is able to detect when a particular wheel is spinning faster than the others, then it applies braking pressure and controls engine output, to restrain wheelspin or lock-up when climbing and descending.
Dual Variable Valve Timing (VVT-i):
Dual Variable Valve Timing with intelligence (Dual VVT-i) alters the inlet and exhaust valve timing in accordance with engine speed, load, temperature and throttle position. This means at low engine revs, it optimises valve timing to increase low-end torque, while at higher speeds it increases midrange and top end power. In addition, by minimising the period of valve overlap (the condition where both the inlet and exhaust valves are open) at low engine revolutions Dual VVT-i helps reduce emissions and improves fuel economy.
Electronically controlled Continuously Variable Transmission (E-CVT):
The Electronically controlled Continuously Variable Transmission (E-CVT) seamlessly combines the driving force of the V8 petrol engine and the electric drive motor. It allows the vehicle to accelerate without gear changes, so speed increases remarkably quietly and seamlessly. It has a sequential-shift feature, so you can select a degree of engine braking for corner entry and hill descents. It also allows you to experience a sequential shift feeling when accelerating or decelerating.
Intelligent Parking Assist (IPA):
When parallel parking, firstly align the car forward of your intended parking space. Touch the appropriate buttons on the EMV screen, select reverse and remove your hands from the steering wheel.  Using inputs from the parking sensors, IPA+ calculates the optimum direction, controls the steering and parks the car, while you regulate the speed with the foot brake.  Naturally you should also maintain a watchful eye while parking.  You may override IPA any time you wish using the accelerator pedal or the steering wheel.  Whenever you prefer to take matters into you own hands, the parking sensors and Rear View Camera (RVC)^ with Rear Guide Assist (RGA) help guide you.

Intelligent Park Assist is designed as a driver assist device only and should not be used as a substitute for skilled driving and safe parking practices. The driver should watch the area into which the vehicle is to be reversed, react appropriately and ensure compliance with all road rules. Intelligent Parking Assist requires brake control.

^Rear View Camera is designed as a driver assist device only and should not be used as a substitute for skilled driving and safe parking practices.  The area into which the vehicle is to be reversed must be visually monitored by the driver while parking.

Lexus Hybrid Drive:
Hybrid is about the conservation of energy. The Lexus Hybrid Drive System not only delivers performance, it saves energy at every stage. For example, any energy from the petrol engine that is not required to propel the vehicle is converted to electricity and stored for later use. Kinetic energy that would otherwise be wasted as heat energy through the brakes when slowing the vehicle is converted to electrical energy through regenerative braking and stored. That stored energy is used, via the electric drive motor, to accelerate the vehicle. As part of the Lexus system's energy saving strategy, there is near zero wastage (or slippage) in the transmission. While the transmission acts as an E-CVT and drives exactly as you would a sequential-shift automatic transmission, it conserves energy by reducing any slippage - it provides direct mechanical drive. There is no torque converter and there are no rubber belts.
NOx emissions:
NOx emissions refer to nitrogen oxides which are formed when fuels are burned at high temperatures and, when released, form fine particles and ozone smog that are harmful to our health.
Rear View Camera (RVC):
Located just above the rear licence plate on the boot there is a Rear View Camera (RVC)^. Whenever reverse gear is selected, it automatically relays a colour image to the Electro Multi Vision (EMV) screen on the console, showing what's immediately behind you. With the additional Rear Guide Assist (RGA) feature, the screen also displays coloured grid lines that indicate the predicted path into the parking position (with your current steering angle and full steering angle) and if the space is long enough for the vehicle.

^Rear View Camera is designed as a driver assist device only and should not be used as a substitute for skilled driving and safe parking practices.  The area into which the vehicle is to be reversed must be visually monitored by the driver while parking.
Regenerative Braking :
When slowing down or braking, energy is lost in a normal vehicle - largely through the brakes creating heat. With Regenerative Braking, the Lexus Hybrid Drive system ensures as much energy as possible is captured, by using the electric drive motor as a generator. It captures the vehicle's 'kinetic' energy and converts it into electrical energy, which is then stored in the hybrid system battery. This electricity is later put to good use by the electric drive motor to propel the vehicle.
Traction Control (TRC):
Slippery or undulating terrain, or a situation where one side of the vehicle is on a high-grip surface and the other side on a low-grip surface, can cause wheel spin on one or more wheels, and hence potential loss of control. Traction Control (TRC) modulates the vehicle's hybrid drive system and (if necessary) the brakes on the individual wheels to ensure smooth acceleration and improved control.
Variable Gear Ratio Steering (VGRS):
Variable Gear Ratio Steering (VGRS)** tailors the rate of steering response to vehicle speed, providing quick response when parking and optimum steering feel at highway speeds. VGRS has another key benefit. By stepping in with only minimal assistance it can effectively limit the impulse to overcompensate when steering through a corner. In addition, VGRS works with the car's VDIM system to enhance safety in the event of a skid.

**VGRS not available on all Lexus models.
Vehicle Dynamics Integrated Management (VDIM):
VDIM is designed to help maintain control of the vehicle in the event of a loss of traction - such as a front-end or rear-end slide. It achieves this by integrating an number of systems within the vehicle, including electro-hydraulic Electronically Controlled Braking (ECB), Anti-skid brakes (ABS), Electronic Brake-force Distribution (EBD), Traction Control (TRC) and Vehicle Stability Control (VSC) active safety systems with the Adaptive Variable Suspension (AVS), Electronic Power Steering (EPS) and Variable Gear Ratio Steering (VGRS)**.

**VGRS not available on all Lexus models.
Wet-sanded paintwork:
The bodywork receives up to six coats of paint. In between paint coats, robots which simulate the skilful hands of craftsmen, carefully sand the paintwork. Then the final two coats are sanded by hand. The paintwork is rubbed back with wet sandpaper, ensuring a more even finish and richer gloss.
