38SUPRAÐNEW FEATURES
2. Sound Absorbing Materials
Seal material has been newly provided to the bottom of the front pillar, and a quarter service hole cover has been
newly provided to the quarter portion in order to reduce road noise while driving.
The material of sound absorbing material used in the roof side inner garnish, quarter trim, deck side trim and deck
rear trim has been changed to reduce road noise.

CRUISE CONTROL SYSTEM
1. Actuator
The '97 Supra has adopted a new motor type actuator that is both lightweight and simple in construction.
The basic construction and operation of this actuator are the same as in the '96 4Runner with 5VZ±FE engine.
For details, see the 1996 4Runner New Car Features (Pub. No. NCF126U), page 71.
2. Cruise Control ECU
Manual Cancel Function
The manual cancel function, which cancels the cruise control when the parking brake is operated, has been
discontinued.

 DRIVE SHAFT
The drive shaft outboard joint of the 2JZ±GE engine model has been changed from the cross±groove type CJV
(Constant±Velocity Joint) to the Rzeppa type CVJ.
As in the '96 model, the 2JZ±GTE engine model uses the drive shaft consisting of cross±groove type CVJs for both
the inboard and outboard joints.
 BRAKES
1. General
The size of the master cylinder for the 2JZ±GTE engine model has been increased to realize excellent brake feeling.
The ABS actuator has been changed from the conventional three±position solenoid valves to a combination of
compact two±position solenoid valves, thus achieving a compact and lightweight configuration.
3±channel type ABS with 4±speed sensor is used on the 2JZ±GE engine model.
4±channel type ABS with 4±speed sensors and linear type deceleration sensor is used on the 2JZ±GTE engine
model.
