JLOW VIBRATION AND LOW NOISE BODY
1. General
Effective application of vibration damping and noise suppresant materials reduces engine and road noise.
2. Noise Absorbing and Vibration Damping Materials
D Sandwich panels are used in the dash panel and rear wheel housings, and in the front floor tunnel to
reduce engine and road noise.
D Asphalt sheets are optimally placed to reduce engine and road noise for quieter vehicle operation.
D Foamed urethane sponge and foamed seal material are applied onto the roof panel and pillars to reduce
wind and road noise.
D The joining rigidity of the parts in the periphery of the suspension has been increased to reduce road
noise.

3. Sub-Frame
The highly rigid front sub-frame helps reduce noise and vibration.
The engine and the transaxle are installed onto the front sub-frame fitted to the vehicle’s body.
The front lower arms and the steering link are also fitted to the sub-frame. Vibration is suppressed in two
stages by means of a rubber bushing between the body and the sub-frame, and also by rubber bushings
between the sub-frame, the engine and transaxle.

ENHANCEMENT OF PRODUCT APPEAL
JSEAT BELT
D The front seats are provided with a 3-point ELR (Emergency Locking Retractor) seat belt.
D The rear seats are provided with a 3-point ELR and ALR (Automatic Locking Retractor) seat belt.
D The front seats are provided with an electrical sensing type seat belt pretensioner and a seat belt force
limiter. In the beginning of a collision, the seat belt pretensioner instantly pulls up the seat belt thus
providing the excellent belt’s effectiveness in restraining the occupant.
When the impact of a collision causes the tension of the seat belt applied to the occupant to reach a
predetermined level, the force limiter restrains the tension, thus controlling the force applied to the occu-
pant’s chest area.
D In accordance with the ignition signal from the airbag sensor assembly, the seat belt pretensioner activates
simultaneously with the deployment of the SRS airbags for the driver and front passenger.
