To support the power plant, the inertial axis four-point mount system has been adopted. The system has the following features

  1. For the engine and transaxle mounting insulator, the cylindrical liquid seal mount has been adopted. It reduces the idling vibration and acceleration
  2. noise, and improves riding comfort.
  3. For the engine mounting bracket, lightweight and high rigidity aluminum has been adopted to reduce acceleration noise.
  4. For the transaxle mounting bracket, lightweight and high rigidity sheet metal has been adopted to reduce the gear noise.
  5. For the front and rear roll stoppers, insulators developed exclusively for M/T vehicle or CVT vehicle have been adopted. It reduces the idling vibration and acceleration/deceleration shock.
  6. A front axle crossmember has been adopted to improve steering ability.

< 2.0L ENGINE TURBO >

For the power plant support, the inertial axis four-point mounting system is adopted, and the system has the following features.

  1. Environmental-load substances are totally abolished for hexavalent chromium-free and lead-free components.
  2. For the engine and transaxle mounting insulator, the cylindrical liquid seal mountings are adopted. This reduces idling vibration and acceleration noise, and improves riding comfort.
  3. A front axle crossmember is adopted to improve steering ability.
  4. The mass damper is added into the centermember to reduce muffled sound during acceleration.
  5. The front axle crossmember bar is added to enhance rigidity.

REMOVAL AND INSTALLATION < 2.0L ENGINE NON-TURBO >

CAUTIONBefore removing the steering wheel assembly and driver's air bag module assembly, refer to SERVICE PRECAUTIONS and AIR BAG MODULE(S) AND CLOCK SPRING . Position the steering wheel in the straight-ahead position, and remove the ignition key. If you fail to do this, clock spring for SRS may get damage not to operate the SRS (air bag), and it may cause the serious injury of the driver. The parts indicated by * are the bolts/nuts with friction coefficient stabilizer. In removal, ensure there is no damage, clean dust and soiling from the bearing and thread surfaces, and tighten them to the specified torque. After the installation, perform a calibration for the ASC-ECU to learn the steering wheel sensor neutral point. (Refer to STEERING WHEEL SENSOR CALIBRATION ) < Vehicles with ASC >.
