TRANSMISSION & DRIVELINE

SECTION CL: CLUTCH

PRECAUTIONS

This section outlines critical safety precautions and service notices related to the clutch system, including:

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER": Emphasizes the importance of authorized service for SRS components to prevent accidental activation and potential injury. Warns against using electrical test equipment on SRS circuits unless specified and notes that SRS wiring harnesses are typically yellow or orange.
Precautions When Using Power Tools (Air or Electric) and Hammers: Advises against using power tools or striking near Air Bag Diagnosis Sensor Units or other Air Bag System sensors when the ignition is ON or the engine is running, due to the risk of accidental air bag deployment. Recommends switching off the ignition, disconnecting the battery, and waiting at least 3 minutes before performing service.
Precaution for Procedure without Cowl Top Cover: Suggests covering the lower end of the windshield with urethane or similar material to prevent damage when working after removing the cowl top cover.
Service Notice or Precautions for Clutch: Warns against using compressed air for cleaning the clutch disc, recommending a dust collector instead. Advises referring to MA-10, "Fluids and Lubricants" for clutch fluid specifications, not reusing drained clutch fluid, and promptly cleaning any spilled clutch fluid from painted surfaces.
Precautions for Removing of Battery Terminal: Instructs to turn OFF the ignition switch and wait at least 30 seconds before removing the 12V battery terminal, as ECUs may remain active. For vehicles with dual batteries, it's crucial to connect both batteries before turning the ignition ON. After installation, it's recommended to check the "Self Diagnosis Result" of all ECUs and erase any DTCs.
General Precautions: Avoids mineral oils like gasoline or kerosene as they can damage hydraulic system rubber parts. States that the Concentric Slave Cylinder (CSC) should not be reused as dust on sliding parts can damage seals and cause fluid leakage. Advises against disassembling the clutch master cylinder and CSC.

PERIODIC MAINTENANCE

CLUTCH PEDAL

Inspection and Adjustment

The Height of Clutch Pedal

1. Turn the floor carpet.
