Buick Riviera 1991 - CAUTIONS & WARNINGS ANTI-LOCK BRAKE SYSTEM


On models equipped with anti-lock brake systems, ALWAYS observe the following cautions:

  • DO NOT attempt to bleed hydraulic system without first referring to appropriate ANTI-LOCK BRAKE SYSTEM article in the BRAKES Section.
  • DO NOT mix tire sizes. As long as tires remain close to the original diameter, increasing the width is acceptable. Rolling diameter must be identical for all 4 tires. Some manufacturers recommend tires of the same brand, style and type. Failure to follow this precaution may cause inaccurate wheel speed readings.
  • Use ONLY recommended brake fluids. DO NOT use silicone brake fluids in an ABS-equipped vehicle.

Buick Riviera 1991 - INFLATABLE RESTRAINT SYSTEM (AIR BAG SYSTEM)


CAUTION: The Diagnostic Energy Reserve Module (DERM) can maintain enough voltage to cause a deployment of the inflator module for up to 10 minutes after the ignition switch is turned off and the battery is disconnected. Many of the service procedures require disconnection of the inflator module to avoid an accidental deployment.
