Engine Type:
Likely V8 gasoline or inline-6 gasoline/diesel, depending on specific W463 sub-model in 1997. Specific engine codes (e.g., M112, M119, OM602, OM603) would be detailed in the manual.
Typical Power Output:
Varies significantly by engine. For example, the G500 (W463) likely featured a 5.0L V8 producing around 237-296 hp, while diesel variants would have lower output.
Fuel Delivery:
Fuel injection systems (e.g., Bosch KE-Jetronic or later EIS/ME systems for gasoline, mechanical injection for diesel), detailed in the manual.
Cooling Type:
Liquid-cooled, pressurized system. Manual will detail radiator, coolant types, thermostat, and pump specifications.
Oil Type And Capacity:
Manual will specify required engine oil viscosity grade (e.g., 10W-40, 15W-40 for diesel) and API service classification, along with oil filter part numbers and capacity. Example: MB 229.1 or MB 228.3 for diesel.
Type:
Likely a 4-speed automatic (e.g., 722.6 '5G-TRONIC' for some petrol models) or 4/5-speed manual transmission for diesel variants. The manual covers all variants.
Optional Transmission:
Depending on engine and market, both automatic and manual transmissions were available. Specific gear ratios and transfer case details are covered.
Transfer Case:
Permanent all-wheel drive with a lockable center differential and often lockable front and rear differentials, all operationally detailed in the manual.
Automatic Transmission Fluid:
Manual will specify the correct ATF type, likely a Dexron-III equivalent or specific MB approval fluid for the 722.6 transmission (e.g., MB 236.10).
Manual Transmission Fluid:
Manual will specify the appropriate gear oil viscosity and API rating (e.g., SAE 75W-90 GL-4/GL-5).
Wheelbase:
Typically around 2850 mm (112.2 inches) for standard wheelbase variants in the W463 generation. Long-wheelbase versions also existed.
Length:
Approximately 4605 mm (181.3 inches) for standard wheelbase.
Curb Weight:
Ranges from approximately 2000 kg (4400 lbs) to over 2300 kg (5070 lbs) depending on engine and equipment.
Towing Capacity:
Generally rated for up to 3500 kg (7716 lbs), but specific limits are detailed in the vehicle's documentation.
Crash Test Information:
While formal NHTSA/Euro NCAP ratings for this era are less common, the robust body-on-frame construction and advanced for its time safety features provided significant passive safety. The manual covers SRS system diagnostics.
Braking System:
Four-wheel disc brakes. Anti-lock Braking System (ABS) was standard. Manual covers ABS system components, testing, and repair.
Traction Control:
Some models may have featured ASR (Acceleration Slip Regulation) as an early form of traction control. Manual will detail its operation and diagnostics.
Supplemental Restraint System:
Driver and front passenger airbags (SRS). Manual details airbag module replacement, sensor diagnostics, and fault finding.
Seat Belts:
Pre-tensioning seat belts were likely standard. Manual covers seat belt system inspection and repair.
Audio System:
Likely featured an aftermarket-style or basic factory radio with cassette and possibly a CD player. Manual will detail speaker replacement and wiring, head unit removal/installation.
Cruise Control:
Standard on many models. Manual covers diagnosis and repair of the cruise control system components (actuator, module, switches).
Multiplex Communication:
The W463 began incorporating multiplex wiring and CAN communication systems for various control modules. The manual provides schematics and diagnostic procedures for these networks.
Oil Change Interval:
Typically every 7,500 to 15,000 miles (12,000 to 24,000 km) or 12 months, depending on engine oil type and driving conditions. Manual will provide specific factory recommendations.
Transmission Fluid Change:
Automatic transmissions often recommended fluid changes every 30,000-60,000 miles. Manual will specify exact intervals and procedures.
Other Maintenance:
Includes spark plug replacement, air filter replacement, coolant flush, brake fluid replacement, differential fluid changes, and transfer case fluid changes at specified intervals detailed in the manual.
Coolant Type:
Typically a G48 or similar ethylene glycol-based coolant with MB approval (e.g., MB 325.0). Manual will specify.
Brake Fluid Type:
DOT 4 or DOT 5.1 brake fluid. Manual will confirm the specific requirement.
Common G Class Issues:
While known for durability, common issues can include rust on body panels (especially around wheel wells and tailgate), aging rubber seals and hoses, potential for HVAC blower motor failure, and occasional issues with the electronically controlled differentials/transfer case if not maintained. The manual provides troubleshooting for all these systems.
Mercedes-Benz Legacy:
Mercedes-Benz has a long history of engineering robust and durable vehicles, including military applications and luxury SUVs. The G-Class builds on this reputation for ruggedness and engineering excellence.
W463 Development:
The W463, introduced in 1989, marked a significant shift from the more utilitarian military-focused W460/461 G-Wagens. It introduced more creature comforts, independent front suspension (on some variants), and a more refined interior while retaining its core off-road prowess. The 1997 model year falls within the early-to-mid W463 production run.
Manufacturing Location:
Graz, Austria (by Magna Steyr under contract for Mercedes-Benz).
