Overdrive gear for fuel efficiency. 📐 Dimensions Exterior Length: Approx. 4.9m (early models) to 4.7m (facelift) Width: Approx. 1.8m Height: Approx. 1.4m (adjustable with Hydractive suspension) Weights Curb Weight: Approx. 1500-1700 kg depending on engine and equipment. 🛡️ Safety Features Ratings Euro Ncap Rating: Not available for this era of vehicle, as Euro NCAP began testing in 1997. Early testing was less standardized. Active Features Active Safety Systems: Anti-lock Braking System (ABS) on many models, early traction control on some V6 models. Passive Features Passive Safety Features: Front airbags (standard on later models), seatbelt pre-tensioners, reinforced safety cell, side impact beams. 💡 Technology Features Infotainment Radio System: Factory fitted radios with cassette players, often with steering wheel mounted controls on later models. Climate Control: Automatic climate control (Thermotronic) available on higher trim levels, offering digital temperature and fan speed control. Driver Assistance Cruise Control: Available as an option on many models, particularly higher engine variants. Parking Sensors: Not typically fitted to pre-facelift models. Later models may have had aftermarket or dealer-fitted options. Connectivity Bluetooth: Not a standard feature for the era. Bluetooth connectivity would be an aftermarket addition. 🔧 Maintenance Service Intervals Oil Change Interval: Typically every 10,000 km or 12 months, whichever comes first (varies by engine oil type and driving conditions). Timing Belt Replacement: For V6 engines, typically every 80,000 - 100,000 km or 5-6 years. For 4-cylinder engines, consult manual as some had timing chains. Suspension Fluid Change: Hydropneumatic fluid (LHM - Liquide Hydraulique Minéral) should be checked regularly and changed according to manufacturer recommendations, often around 60,000 km. Fluid Specifications Engine Oil Grade: Varies by engine: e.g., 10W-40, 5W-40 (synthetic for V6). Consult specific engine requirements in manual. Coolant Type: Ethylene glycol based antifreeze, typically a 50/50 mix with distilled water. Brake Fluid Type: DOT 4 Hydropneumatic Fluid: LHM Plus (Green) is crucial for the Hydractive system. Using incorrect fluid can cause severe damage. Known Issues Suspension Reliability: Hydropneumatic system can be complex; leaks from spheres, pumps, or lines are possible. Requires specialized knowledge and tools. Electrical Gremlins: Can suffer...
