🛡️ Safety Features

Crash Test Ratings:

Lacks modern safety ratings (e.g., Euro NCAP, NHTSA) due to its design era and manufacturing focus. Generally considered basic by contemporary standards.

Active Safety Features:

Standard 4WD system with low-range provides enhanced traction and control off-road and in adverse conditions. Basic brake system.

Passive Safety Features:

Seat belts (often basic lap belts in early models, 3-point in later ones), body-on-frame construction for ruggedness. Limited impact absorption structures compared to modern vehicles.

Safety Considerations:

Due to age and design, focus on maintaining brakes, tires, and steering components is critical for safe operation. Manual addresses these systems.

🔧 Maintenance

Engine Oil Change:

Every 5,000-7,500 km (3,000-5,000 miles) or 6-12 months, whichever comes first, especially for carbureted models and those driven in harsh conditions.

Transmission Fluid Change:

Spark Plugs:

Inspect every 10,000-15,000 km (6,000-9,000 miles), replace as needed or per manual recommendation (e.g., 20,000-30,000 km).

Air Filter:

Inspect every 10,000 km (6,000 miles), replace annually or more often in dusty conditions.

Coolant Type:

Ethylene glycol based coolant, typically 50/50 mix with distilled water. Specific LADA/AvtoVAZ recommendations may vary.

Brake Fluid Type:

DOT 3 or DOT 4, glycol-based hydraulic brake fluid.

Common Issues:

Rust/corrosion on body and chassis, electrical gremlins (especially wiring insulation degradation over time), starter motor reliability, clutch wear, potential gearbox synchro issues, carburetor tuning difficulties, occasional overheating if cooling system maintenance is neglected.

Maintenance Recommendations:

Regularly inspect for rust, especially in wheel arches, sills, and door bottoms. Keep electrical connectors clean and protected. Pay close attention to cooling system maintenance. Check for oil leaks from engine and drivetrain.
