Gasoline engines might also be present depending on market. Specific engine codes vary. Performance Horsepower Torque: Specific horsepower and torque figures vary significantly by engine and market. The manual will detail these for each variant. Fuel System Fuel Delivery: Commonly features direct injection diesel with mechanical or electronic fuel injection pumps, and potentially common rail systems on later models within the range. Gasoline engines would feature port or direct injection. 🔧 Transmission Standard Transmission Types: Predominantly 5-speed and 6-speed manual transmissions. Some models may offer automatic transmissions (e.g., 4-speed automatic). Optional Optional Transmissions: Automatic transmission availability depends on specific N Series model and market configuration. Features Transmission Features: Manuals will cover clutch actuation, gearbox overhaul, fluid capacities, and shift mechanism adjustments. 📐 Dimensions Exterior Wheelbase Options: Multiple wheelbase configurations are available for the N Series, impacting overall length and turning radius. The manual will provide specifications for each. Weights Gvwr: Gross Vehicle Weight Rating (GVWR) varies significantly by model (e.g., NQR models will have higher GVWR than NLR models). The manual will detail these ratings and payload capacities. 🛡️ Safety Features Ratings Crash Test Data: While specific crash test ratings for this era of commercial vehicles are less common in a public domain sense, the manual will cover safety-related systems like brakes, steering, and occupant restraint systems. Active Features Braking System: Hydraulic disc brakes (front), drum brakes (rear), anti-lock braking system (ABS) may be optional or standard on certain models/years. Passive Features Occupant Safety: Seat belts, reinforced cab structure, potential for airbags (less common on basic configurations of this era). 💡 Technology Features Infotainment Audio System: Basic AM/FM radio and cassette player or CD player were common. Manual will cover wiring and basic troubleshooting. Driver Assistance ABS: Anti-lock Braking System (ABS) availability varied. Manual will detail its operation and troubleshooting if equipped. Connectivity Electrical Systems: The manual will provide detailed wiring diagrams for all electrical systems, crucial for diagnosing any issues with sensors, actuators, or control modules. 🔧 Maintenance Service Intervals Recommended Intervals: The manual will provide detailed service interval recommendations for oil changes, filter replacements, coolant flushes, brake inspections, and other critical maintenance tasks, typically based on mileage or time. Fluid Specifications Engine Oil: Specific viscosity grades (e.g., 15W-40, 10W-30) and API service classifications for diesel engines will be detailed. Manual will also specify for transmission fluid, brake fluid, power steering fluid, and coolant.
