    2. 8GR-FXS Engine


      1. The 8GR-FXS engine is a 3.5-liter, 24-valve DOHC V6 Direct injection 4-stroke gasoline engine Superior version (D-4S). This engine uses both direct injection and port injection systems. In addition, this engine uses the Dual Variable Valve Timing-intelligent (Dual VVT-i) control, Direct Ignition System (DIS), and Electronic Throttle Control System-intelligent (ETCS-i). These control functions achieve improved engine performance, fuel economy, and clean emissions.

      1. An Adaptive Variable Suspension system (AVS) is used.

      2. A multi-link type suspension is used for the front.

      3. A multi-link type suspension is used for the rear.

    5. Brake Control System


      1. The following brake control functions are provided:


        • Anti-lock Brake System (ABS)

        • Electronic Brake force Distribution (EBD)

        • Brake assist

        • Traction Control (TRC)

        • Vehicle Stability Control (VSC)

        • Steering cooperative control

        • Hill-start assist control

        • Brake hold function

    6. Front Brake


      1. A ventilated disc brake is used.

    7. Rear Brake


      1. A ventilated disc brake is used.

    8. Parking Brake


      1. A duo servo inner drum type parking brake is used.

      2. An electric parking brake system is used.

    9. Steering


      1. Power tilt, power telescopic and Electric Power Steering (EPS) systems are used.

      2. A Variable Gear Ratio Steering (VGRS) system is used.

      3. A Dynamic Rear Steering (DRS) system is used.

      4. The LEXUS Dynamic Handling (LDH) system*is used, which consists of the Variable Gear Ratio Steering (VGRS) system which controls the turning angle of the front wheels and the Dynamic Rear Steering (DRS) system which controls the turning angle of the rear wheels.

    10. Drive Mode Select


      1. The drive mode select is a function where control characteristics switches of the powertrain (hybrid control system), chassis [Adaptive Variable Suspension system (AVS), Vehicle Dynamic Integrated Management (VDIM), Electric Power Steering (EPS) system, LEXUS Dynamic Handling (LDH) system*] and air conditioning (air conditioning system) are integrated. This function optimally controls each system according to the driving mode selected by the driver.

        Sport S+ Power2 Sport Sport Sport Sport Normal

        *: Models with LEXUS Dynamic Handling (LDH) system

      3. The control characteristics in each drive mode are as follows:

        Drive Mode Control Characteristics
        Normal Performs control for normal driving.
        Eco Performs control for driving with improved fuel efficiency by generating torque more gently than Normal mode according to accelerator pedal depression while suppressing air conditioning cooling and heating operations.
        Sport S Improves accelerator response by controlling the hybrid control system to perform control for driving that requires powerful acceleration.
        Sport S+

        Comprehensively controls the AVS, VDIM, EPS system and LDH system*in addition to the hybrid control system of Sport S mode to ensure maneuverability and stability to perform control for sporty driving.
        Comfort Mainly uses the lower damping force range with the Adaptive Variable Suspension System (AVS) compared to Normal mode, performing control to achieve a comfortable ride.

      4. Custom mode is provided. Custom mode is a function where the control characteristics of each system can be freely selected and combined by the driver. Powertrain (Normal/Eco/Power), chassis (Normal/Sport/Comfort) and air conditioning (Normal/Eco) combinations can be freely selected to support the specific needs of the driver. Refer to the Repair Manual for the details of the custom mode setting method.

        Tech Tips

        When Power is selected for the powertrain in custom mode, the control characteristic of the hybrid control system is set to Power1.
