AUTO LSD Indicator Light Remains ON
BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: AUTO LSD Indicator Light Remains ON
AUTO LSD Indicator Light Remains ON
DESCRIPTION
Operation of the VSC OFF switch changes the vehicle from normal mode to AUTO LSD mode (TRAC OFF mode) to VSC OFF mode. During normal mode, pressing the VSC OFF switch for a short amount of time changes vehicle to AUTO LSD mode (TRAC OFF mode). During AUTO LSD mode (TRAC OFF mode), the combination meter's AUTO LSD indicator light and slip indicator light illuminate, the AUTO LSD becomes inoperable, and TRAC operation is disabled.
HINT: The AUTO LSD does not operate even if the VSC OFF switch is pressed under the following conditions:
- TRAC or VSC system is faulty.
- Temperature inside the hydraulic brake booster increases and the AUTO LSD operation is suspended.
