Anti-lock Braking System (ABS) was standard on VT and optional/standard on 2WD variants depending on specific market configurations.

Seatbelts:

Three-point inertia-reel seatbelts

💡 Technology Features

Audio System:

Factory fitted audio system (likely AM/FM radio with cassette player), with speakers integrated into the cabin. Limited by 1993 technology standards.

Driver Aid Features:

ABS, and for the VT model, the all-wheel-drive system itself acts as a significant driver assistance feature for traction and stability.

Connectivity Features:

None in the modern sense. Connectivity would be limited to basic vehicle diagnostics and potentially aftermarket additions.

🔧 Maintenance

Oil Change Interval:

Typically every 7,500-10,000 miles or annually, whichever comes first, but highly dependent on driving conditions and manufacturer recommendations for high-performance engines.

Engine Oil Specification:

Specific viscosity grade will be detailed in the manual, likely a high-quality synthetic (e.g., 10W-50 or 20W-50). Capacity approx. 10-12 liters.

Coolant Specification:

Ethylene glycol-based antifreeze coolant, typically a 50/50 mix with distilled water. Capacity approx. 15-18 liters.

Brake Fluid Specification:

DOT 4 or DOT 5.1 high-performance brake fluid.

Manual Transmission Fluid:

Specific GL-4 or GL-5 gear oil, viscosity will be specified in the manual.

Common Issues Diablo:

Potential issues may include aging rubber and plastic components, HVAC system reliability, early electronics/ECU quirks, and the need for specialized maintenance due to its exotic nature. Clutch wear is also a factor for high-mileage vehicles.

📚 Vehicle History
